<p>This paper will review the findings from a research project concluded in 2004, which had the primary goal of learning more about the natural behaviors of people choosing materials for inclusion in a digital archive. Project participants, retiring faculty at the University of North Carolina at Chapel Hill had a number of tasks to perform. They had to 1) survey and choose the materials to include in the archive; 2) develop a “collection development plan” defining the nature of their materials, their intended audience, and the organizational scheme of their collection; 3) provide materials for digitization; 4) supply metadata for the digitized materials; and 5) write a “finding aid” for their collection. The research team digitized the materials and developed a demonstration repository website for the participants. This paper will focus on the disconnect between traditional archival theory and the users’ natural behavior; and the challenges of developing an archival collection given current digital repository software.</p>

archives
licensing
intellectual property rights
The need to negotiate licenses protecting the rights to intellectual property in archives is an emerging and complex area. This article provides archivists with a better understanding of the legal and economic issues arising from commercial requests for archival materials, examining five key areas relating to licensing: the technology, the players, the economics, the rights and the consequences. The article presents guidelines, strategies, and a sample licensing agreement to help archivists make informed decisions about whether and on what terms to license materials from their collections for commercial use.

Corporate Training Assessment Technique: Risk Factors Associated with Misappropriation of Assets
Strand, Carolyn A.
Lancaster, Kathryn A.S.
Thorne, Jerry
2002-01-01T08:00:00Z
Journal of Forensic Accounting
Article
<p>Due to rapid advances in technology, companies are spending record amounts of money on training as they seek to increase employee skills (Armour 1999). Because managers believe that corporate fraud is a growing problem, an important skill for all employees should be the ability to recognize the risk factors that are frequently associated with fraud. A number of instructional cases have been developed that focus on the problems of employee fraud and unethical management practices. Training materials and professional standards now include more detailed information on the subject of fraud and the auditor's responsibility, as well as management's responsibility, with respect to the detection of fraud. The next logical step is to assess employee training on this topic. In particular, can employees recognize risk factors when they are embedded in an actual instance of misappropriation of assets? We offer a case, based on an actual instance of misappropriation of assets, that may be used as a corporate training assessment technique (CTAT). Since training dollars are an important resource allocation decision, assessment of the training that is provided to employees is essential. Further, since effective teaching produces learning, then evaluation of learning is critical to assessing teaching effectiveness. We also include instructions for using the CTAT, teaching notes, and suggestions for developing additional instructional cases.</p>

Creating Effective Teams in a Classroom Environment
Lancaster, Kathryn A.S.
Crother, Cyndi A.
2003-10-01T07:00:00Z
Journal of Business and Behavioral Sciences
Article
<p>For over a decade, companies have been concerned that new graduates are often not prepared to work in jobs where there they are required to contribute as a member of a team. In response, many educators have adopted team-based learning pedagogies, often referred to as cooperative learning. The use of teams has created additional class management issues and added to the complexity of class dynamics. While most students find team activities helpful, the authors have experienced a variety of problems encountered by various teams. For example, some class teams never function as a team, and the members end up working in subgroups or individually. There is also the risk that one member dominates the other team members or shirks his/her responsibilities. It is important to give students time to develop their interaction skills. To help students get the most out of the team-learning experience and help them develop habits that promote positive team interactions, we present ten in-class team development activities. Because enhancing team skills is of secondary concern (first being mastery of course content), each activity is designed to take at most 15 minutes. The exercises may be used throughout a semester, or the professor may elect to implement one or a few of the activities. Regardless, these activities will help even the best performing teams become more functional, will reduce the likelihood of team conflicts, and help students develop team skills. These activities were modeled after those in Lencioni's Five Dysfunctions of a Team: A Leadership Fable (2002).</p>

Article
<p>Preventing fraud is a big responsibility for all levels of financial management— manager, controller, and CFO. Since managers are responsible for preventing and detecting fraud, they must constantly ask themselves,“What more can we do?” Most fraud is discovered through internal controls, auditors, and employees who notice suspicious activities. Therefore, you may want to consider training fiscal employees and managers to detect fraud.</p>

Making Better Use of Information: Aiming Towards "True North"

<p>'If I only had the right information, I could make an informed decision'. How often have you heard that comment? With the information technology currently at our disposal, one would think that the right information would be available and that all decisions would be sound. However, users must still determine what data provides valuable information and what are the limitations of the soundness of a decision. What has been missing from most decision models is prediction awareness, as well as a 'true north' compass reading for the organization, based on goals that reflect the system within the organization and that within which the organization operates. We propose that it is easier to identify what information is needed to stay on course (true north) then make that information available to all decision makers, who can then make more holistic informed decisions when such a compass reading exists.</p>

An Evaluation of the Usefulness of Web-based Financial and Environmental Performance Information Provided by Oil and Gas Companies
Lancaster, Kathryn A.S.
Strand, Carolyn A.
Carr, Janice
2002-03-01T08:00:00Z
Oil, Gas and Energy Quarterly
Article
<p>Environmentally conscious investors require financial information in addition to environmental information to evaluate a company's performance. Sources of such information include organizations that specialize in providing environmental performance data, such as the Council on Economic Priorities (CEP) or the Investor Responsibility Research Center (IRRC). Both of these organizations research, evaluate, and rank companies based on a variety of metrics, and both charge for their service. Through company websites, the Internet offers another potential source of information, since most companies have a "web presence." However, information supplied on a company website has the risk of bias (i.e. the website may be a marketing tool for the company). This potential bias leads to the question of whether information provided by firms is sufficient for an environmentally conscious investor to make an informed decision.</p>

Evidence on the Effectiveness of Using Tax Credits to Promote Energy Conservation
Lancaster, Kathryn A.S.
Kinney, Michael R.
Robison, Jack
2001-12-01T08:00:00Z
Oil, Gas and Energy Quarterly
Article
<p>The country seems to have quickly embarked on a new energy crisis. "From Manhattan to Montana, worries are mounting that skyrocketing power prices and rolling blackouts will soon spread from their epicenter in California.... Concern about the power picture extends to the top levels of the Bush Administration as it attempts to hammer out a new energy policy." As politicians search for possible solutions to the current crisis, incentives for energy conservation are often mentioned as a possible remedy. A recent Congressional Research Service Issue Brief describes several potential bills. Two create a refundable tax credit for up to 50% of increased residential energy costs, a third establishes a 15% residential tax credit for homeowners who purchase photovoltaics and solar thermal equipment. Because tax incentives have been used in past crises, a logical step should be to examine the policies used to determine if they were effective and should be utilized in the future. This paper reports the results of a study of the Energy Tax Act of 1978's provisions relating to residential energy credits.</p>

Lipschitz Spaces on the Surface of Unit Sphere in Euclidean n-Space
Greenwald, Harvey
1974-01-01T08:00:00Z
Pacific Journal of Mathematics
Article
<p>This paper is concerned with defining Lipschitz spaces on Σn-1 the surface of the unit sphere in Rn. The importance of this example is that Σn-1 is not a group but a symmetric space. One begins with functions in Lp(Σn-1),1≤p≤∞. Σn-1 is a symmetric space and is related in a natural way to the rotation group SO(n). One can then use the group SO(n) to define first and second differences for functions in Lp(Σn-1). Such a function is the boundary value of its Poisson integral. This enables one to work with functions which are harmonic. Differences can then be replaced by derivatives.</p>

Undergraduate Program
Projects
The WP/IGSFC (Goddard Space Flight Center)
Projects Program is an off-campus, multi-disciplinary
opportunity for students to complete their capstone design
project requirement during 10 weeks of on-site project work.
Students accepted into this program are required to spend
one term in a project preparation course where they carry
out background research, interact with their project
mentor(s) at the space center, and write a detailed project
proposal. At the completion of the preparation course and
several weeks before the start of the following academic
year, the students relocate to the Washington area and work
full time for ten weeks on their projects at the Goddard
Space Flight Center. This project center is at the forefront
of the WPI emphasis on "real world" project experience as
a cornerstone of its undergraduate educational plan.
Among other benefits, this off-campus program clearly
demonstrates that significant contributions can be expected
from WPI student teams working on complex engineering
and science projects.

The Evolution of the WPI Advanced Space Design Program - An Evolving Program of Technical and Social Analysis Using the NASA Space Shuttle for Engineering Education
Looft, Fred J.

1991-02-01T08:00:00Z
IEEE Transactions on Education
Article
In December of 1982, Worcester Polytechnic Institute, with
the cooperation and support of the MITRE Corporation, initiated a
primarily undergraduate educational program to develop experiments
to be flown onboard a NASA Space Shuttle. Christened the MITRE
WPI Space Shuttle Program, it sponsored the development of five educationally
meritorious experiments over a period of four years. Although
the experiments were ready to fly in early 1986, the Challenger
disaster delayed their flight until the Spring of 1991. The delay notwithstanding,
the benefits of the first program were sufficient to justify
the development of a second set of experiments. More comprehensive
in scope, this new venture, named the Advanced Space Design Program,
addresses both technical and social areas of interested related
to space flight. This paper presents a general historical overview and
self-assessment of WPI's space design programs. Although some of the
material presented has been published elsewhere, most of the material
presented is new in that it represents an analysis of the problems and
pitfalls we have encountered over the past nine years.

On the phenomenon of vortex street breakdown
Durgin, William W.
Karlsson, Sture K.F.
1971-01-01T08:00:00Z
Journal of Fluid Mechanics
Article
A von Kármán vortex street generated in the usual way was subjected to a
deceleration, thereby changing the ratio of longitudinal to lateral spacing between
the vortices. Distortion of the individual vortices followed which resulted
in annihilation of concentrated vortex regions and creation of a stationary wake
flow. This wake flow was itself dynamically unstable and developed into a
new vortex street of a different frequency from the initial one. The breakdown
of the initial vortex street is qualitatively explained by considering the convection
of a concentrated vortex region due to the motion imposed by all the other
vortices.

Educating Engineering Students in Entrepreneurship
Durgin, William W.
Zwiep, Donald N.

ASEE/SEFI/TUB International Colloquium
Article
<p>Since it’s founding in 1865, the faculty, students, and alumni of Worcester Polytechnic Institute have been responsible for the establishment of nearly all the manufacturing industry in the region. Beginning with the Norton Company, a world-wide abrasives manufacturer now owned by Saint Gobain, to recent biotechnology companies, they have combined confidence, innovation, and resourcefulness to continuously accomplish what is now referred to as technology transfer to form start-up companies. By following the historical development of these firms, we seek to determine some of the traits and environmental factors that have fostered the continual entrepreneurial success of the founders.</p>
<p>Worcester Polytechnic Institute was founded by leading industrialists to provide graduates trained in the mechanical arts in order to support the burgeoning manufacturing community of the North American industrial revolution. The educational philosophies of the two principal financial contributors were substantially at odds: one believed that the traditional “book-learning” as practiced in many of the early American universities would be the appropriate curriculum while the other believed that a hands-on apprenticeship in a workshop environment would be more suitable. As it turned out, each financed the construction of a major building; one to provide classroom instruction and the other mechanical shops and laboratories. This theory and practice philosophy still prevails today and was also adopted by such colleges as Rose-Hulman, Illinois Institute of Technology (formerly Armour Institute) and Georgia Tech.</p>
<p>From the beginning, WPI students conducted independent research and development projects embodied in a senior thesis requirement until 1970 and in the Major Qualifying Project, one of the primary degree requirements, subsequently. Students and faculty work together to solve open-ended projects derived from real problems of industry. It will be argued that the technological self-reliance, active learning, and discovery embodied in such projects promote entrepreneurship. Examples will include: Wyman Gordon, automotive and aircraft forging; Morgan Construction, steel mills; Alden Research Laboratory, hydraulic research; Jamesbury Corporation, ball valves; Viva Scan, biomedical sensors; NASA, the area/drag rule development and DEKA, the stair climbing wheelchair.</p>

Article
The WPl PLAN, adopted by the WPl faculty in
1970, strongly anticipates current thinking about student outcomes assessments by structuring degree requirements that mandate that students demonstrate their ability to perform professional functions embodied
in ABET Criteria 2000, especially Criteria 3 and 4. The WPI faculty has also practiced both student and self evaluations of these outcomes through respectively grades and peer review (both departmental and campus-wide) of student performance.

Article
Six WPI engineering programs were evaluated
under Criteria 2000 during a pilot accreditation visit in 1996. The WPI PLAN consists of degree requirements focused on the achievement of outcomes related to those of Criteria 2000. The mapping of degree requirement outcomes to the elements of the Criteria hinged on the translation of student performance metrics and their interpretation. Not surprisingly, substantial effort was necessary to ensure the identification of all elements of Criteria 2000, including the applicable Program Criteria in
the academic program outcomes.

A joint undergraduate research project
between University of Puerto Rico at Mayagüez (UPRM) and Worcester Polytechnic Institute (WPI) started four years ago. Each year a group of students, varying between six and ten, from WPI will come to Puerto Rico to work with a group of students, varying from six to ten, from UPRM on a well defined research
project. Although the topics of the projects have been different but all follow the same goal, Vibration Control of Structures by Utilizing Shape Memory Alloys. Each year the project starts on January and ends on May. Both groups of the students will start
the project simultaneously on their respective
university. Seven weeks after the start of project, WPI students come to Puerto Rico and joint the UPRM group and continue their research as "one group." The requirements for completion of these projects are two major presentations, one at each university, and
one written report. The presentations are all open to public, and students, faculty members, the local industry, and parents are all being invited. The projects have been sponsored by United Technology Center for Loss Prevention and Structural Integrity (CLPSI) at WPI, WPI and UPRM. The results of these projects have been presented at CANAM 97 and 12th
ASCE Conference. There have been also numerous published articles and interview related to these projects in engineering journals and televisions.
Worcester Polytechnic Institute (WPJ) and the
University of Puerto Rico (UPR) entered into a
cooperative agreement in 1995. That agreement enabled broad areas of exchange, collaboration, and joint research.

Ultrasonic Monitoring Method and System for Wake Turbulence Useful at Runways
Johari, Hamid
Durgin, William W.
2000-05-16T07:00:00Z
United States Patent Number: 6,062,076
Article
Two techniques for detecting vortices and their associated circulation are disclosed. The first is termed a closed path configuration, and the second is termed the dual path configuration.
These techniques are useable for the detection of wake turbulence especially in the vicinity of airport runways, which results from wing tip vortices generated by aircraft during take-off and landing. The systems are similar
in that they use ultrasonic measurement techniques to determine the circulation about defined areas. The circulation is reflective of the vorticity associated with trailing vortices,
which are manifest within the area.

Sustainability
<p>In 2000, the Governor of the State of California issued an executive order (D-16-00) that seeks to reduce costs and improve environmental performance of state buildings in all phases of construction, operations and maintenance. The California Integrated Waste Management Board (CIWMB) has provided leadership in implementing this order through initiatives such as the Sustainable Building Task Force. In the realm of post-secondary education, CIWMB also sponsored the Sustainable Environmental Design Education (SEDE) program in collaboration with Cal Poly-SLO. The project will be used to survey and assess existing sustainable environmental design programs, generate a framework for sustainable design education of current and future building and landscape professionals, and assist the Board with dissemination of the resulting sustainable design curriculum. This project seeks to fundamentally change the existing paradigm for environmental design education that has limited the imagination and understanding of designers for the natural processes underlying environmental design. The benefits of this project will ultimately contribute to designers, owners, and operators who achieve higher efficiencies and reduced waste in energy, materials, and water cycles in their buildings and landscapes.</p>

Post-Occupancy Presidio: How lighting and energy design goals compare to performance for the Thoreau Center for Sustainability
McDonald, Margot
1998-06-01T07:00:00Z
23rd Annual American Solar Energy Society Conference Proceedings: Albuquerque, N.M.
Article
<p>The National Park Service was intent on creating a model "green" development at the decommissioned Presidio military base in San Francisco. Two local firms, Community Equity Builders and Tanner Leddy Maytum Stacy (TLMS) Architects forged a partnership which led to one of the first successful historic rehabilitation since the base conversion. Their efforts transformed the turn-of- the-century Letterman Hospital into the Thoreau Center for Sustainability where energy and resource conservation are at the forefront of the building design and operation. The building complex, now occupied for over two years, has been well-documented as a green building and historic rehabilitation project but without the benefits of a post-occupancy evaluation. This study examines the occupied building in three important areas -- daylighting, electric lighting, and thermal comfort -- in order to assess the actual building environmental performance. Results of the first phase of the post-occupancy study, a lighting and thermal comfort user survey, are presented in this paper.</p>

The Design of a Constructivist Learning Experience that uses GPS Technology
Rosenberg, Louis
2004-06-21T07:00:00Z
ED-MEDIA Worldwide Conference on Educational Multimedia, Hypermedia and Telecommunications Proceedings: Lugano, Switzerland
Article
A constructivist learning experience using Global Positioning System (GPS) technology
was conducted with second and third grade students in a public elementary school in Cupertino, California. The students made a map of their school by recording location information with
handheld GPS devices and then graphing the data. The effort, performed by three classes of 20
pupils each, seemed to help students gain intuition about the abstract relationship between maps
and the physical spaces that maps represent. The experience also seemed to help students grasp
complex concepts such as the accuracy of their data, the scale of their maps, as well as the utility of
using technology to perform data collection and analysis.

A Transient Electromagnetic Flowmeter and Calibration Facility
Lefebvre, Paul J.
Durgin, William W.
1990-03-01T08:00:00Z
Journal of Fluids Engineering
Article
An electromagnetic flowmeter was developed to measure transient flows at a data rate of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics of a commercially available electromagnetic flowmeter normally used for steady-state operation. Use of the commercially available flowmeter body, which includes the magnetic coils, core, and signal electrodes, provided a relatively economical means of fabricating the transient flowmeter. A transient flow calibration facility consisting of a free-falling water column was also designed and built. Results of the calibrations are presented and show that the flowmeter can accurately measure transient flows up to the maximum observed acceleration of approximately 1 g.

Lower Mode Response of Circular Cylinders in Cross-Flow
Durgin, William W.
March, P. A.
Lefebvre, Paul J.
1980-06-01T07:00:00Z
Journal of Fluids Engineering
Article
Transverse amplitude responses of a circular cylinder in cross-flow were determined as a function of reduced velocities for a variety of spring constants and damping coefficients. Maxima were found at reduced velocities of 5 and 16, and were of comparable amplitude. The first resonance, designated the "fundamental mode, " was due to normal vortex street excitation of the spring-mass system. The second resonance, designated the "lower mode," occurred when the natural frequency was approximately one-third of the normal vortex shedding frequency. By assuming that the driving force was sinusoidal, it was possible to evaluate the lift coefficients at resonance. Lift coefficients for the lower mode behaved similarly with amplitude ratio but were an order of magnitude lower than lift coefficients for the fundamental
mode. A mechanism was used to oscillate the cylinder transversely at prescribed frequencies and amplitudes. Dominant wake frequencies were determined
from a frequency analysis of the hot-wire signal for a range of velocities and a fixed frequency of oscillation. It was found that synchronization of the shedding
frequency to the forcing frequency did not take place for the lower mode. The familiar "lock-in" region, or frequency synchronization over finite bandwidth, was observed for the fundamental mode only. Since the frequency associated with normal vortex shedding was not suppressed when oscillations took place in the lower mode, it would seem that a low frequency vortex street had not replaced the normal one. It is likely, then, that the spring-mounted cylinder responded subharmonically to the exciting force resulting from vortex shedding. In this regard, however, it was curious that subharmonic response was not found at a frequency ratio of 0.5 as it was at 0.33. A conceptual model, which incorporated features of both the low frequency vortex street and subharmonic response, was developed which accounted for lower mode response at a frequency ratio of 0.33 as well as the lack of response at 0.5.

Ultrasound Technique for Prediction of Statistical Characteristics of Grid-Generated Turbulence
Andreeva, Tatiana A.
Durgin, William W.
2003-08-01T07:00:00Z
AIAA Journal
Article
Ultrasonic measurement techniques can be used to determine some characteristics of turbulent flows. In this work measurements of the difference in propagation times of ultrasonic waves along two paths are combined with the Kolmogorov (<sup>2</sup>/<sub>3</sub>)-power law to study characteristics of grid-generated turbulence. The paper focuses on ultrasonic measurements of turbulent flow using the travel-time technique. The present research is of interest from two points of view. First, it demonstrates an ultrasonic method of investigation of turbulence, and second, it furthers understanding of the effect of turbulence on sound propagation.

Article
An experimental technique for investigation of the behavior of acoustic wave propagation through a turbulent medium is discussed. The present study utilizes the ultrasonic travel-time technique to diagnose a grid-generated turbulence. The statistics of the travel-time variations of ultrasonic wave propagation along a path are used to determine some metrics of the turbulence. Experimental data obtained using ultrasonic technique confirms numerical and theoretical predictions of nonlinear increase of the first-order travel time variance with propagation distance.

<p>This book is about the “community to which we belong”–we, the students, faculty and staff of Cal Poly University and our neighbors. Cal Poly Land encompasses nearly 10,000 acres in four large parcels--two in San Luis Obispo county, and two in Santa Cruz county--making us the second largest university landholder in California and one of the largest in the nation. This land comprises one of Poly's most valuable assets. Its “outdoor teaching and learning facilities” provide laboratories for education and research, house ecosystems and lifeforms, grow food and fiber, inspire recreation and renewal, and remain our legacy from past to future generations. Cal Poly's land has been central to its evolving identity. Enjoying, knowing, using, and taking care of this land are our common concerns. These particular 10,000 acres sustain our work and define our institution. This book aims to increase appreciation and understanding of the land, to enhance our sense of place.</p>

A Problem in Rhetoric: Teaching Writing with Western Culture
Marx, Steven
1993-09-01T07:00:00Z
The Core and the Canon : a national debate
Article
But rather than the large theoretical questions of canon revision that grabbed national headlines last year, I want to talk about a more mundane and limited question that I tried to deal with while teaching at Stanford between 1984 and June 1988. That question addresses one of the practical concerns of this conference on core curriculum: how does one effectively combine a course in English Composition with a course in Western Culture? The problem
delegated to me was to work out a curriculum that would adapt the topics of English Comp to the readings and lectures-a curriculum for a course called Writing With Western Culture.

Article
<p>Peter Greenaway's adaptation of <em>The Tempest</em> is titled <em>Prospero's Books</em>, renaming and representing Shakespeare's play as a work made of books. Prospero begins imagining, speaking and writing <em>The Tempest</em> in his bath while turning the pages of "The Book of Water." It and the other 23 books which inspire and empower him appear in Greenaway's version both as props in the narrative and as "real" documents located in a separate picture plane, where they are described by a donnish voice distinct from that of the protagonist-author.</p>

Ultrasonic flowmeters in determination of correlation functions of velocity and ultrasound wave fluctuations in grid-generated turbulence
Andreeva, Tatiana A.
Durgin, William W.
2003-05-12T07:00:00Z
9th AIAA/CEAS Aeroacoustics Conference and Exhibit: Hilton Head, S.C.
Article
The paper is devoted to the experimental investigation of the statistical characteristics of the grid-generated turbulence produced in a wind tunnel. Ultrasonic time-of-flight method using dual transducers is utilized to develop a methodology for determination of the correlation functions of turbulent velocity and sound speed fluctuations. The ultrasonic flowmeter equation is considered in the form that includes effects of turbulent velocity and sound speed fluctuations. The influence of temperature inhomogeneities on ultrasonic wave propagation is investigated using a set of experiments with a heated grid. Utilization of high-speed digital data acquisition cards and LabView software for the experiments allows collecting a significant amount of statistical data.

44th AIAA Aerospace Sciences Meeting and Exhibit: Reno, NV
Article
This paper describes the experimental proof of concept study for an ultrasonic method of wake vortex detection for airport use. This new acoustic method utilizes travel time of acoustic pulses around a closed path to measure the net circulation within the acoustic path. In this application the closed path encloses the vorticity shed from one side of a Piper PA28
aircraft wing. Magnitude and sign of circulation detected is comparable to the expected circulation generated by the Piper PA28
test aircraft. This study demonstrates the validity of the acoustic method in detecting aircraft wake vortices. Further investigations and applications utilizing this technique are discussed.

The Prophet Disarmed: Milton and the Quakers

Studies in English Literature, 1500-1900
Article
<p>The question of war or peace troubled sixteenth and seventeenth century Europe as much as it troubles our own time. Organized violence-the systematic infliction of irrevocable harm upon one group of human beings by another-was the activity by which the modern nation-state originated, defined itself, rose and fell. During those centuries, most Europeans affirmed, or at least accepted war as the final arbiter of what happened in history. But a significant minority, whether because of inner illumination, abstract reasoning, or the outcome of experience, disputed the primacy of war, maintaining that organized violence was intrinsically evil and that its purposed benefits rarely outweighed its costs. This debate between war and peace influenced the policies of princes, the exhortations of divines, and the speculations of philosophers as well as the daily thoughts of citizens. It also shaped the imaginative productions of artists and writers throughout the early modern period.</p>

Cal Poly Lands located in San Luis Obispo County experience a collection of idyllic microclimates due to their geographical position relative to the Irish Hills and San Luis Range to the south and west, and the Santa Lucia Range to the east. These ridges create sheltered valleys that retard the persistent summer coastal fog common to neighboring communities to the west and the wide seasonal temperature variations of the Salinas and San Joaquin Valley north of the Cuesta Grade.

Cal Poly Land: A Field Guide
Article
<p>Previous chapters have described the vast array of resources that Cal Poly’s officials oversee. As students, educators and others in the surrounding community continue to use Cal Poly Land and surrounding areas, the ecological system and its capacity to recover become strained. In order to ensure that in 100 years students (and other Cal Poly stakeholders) will be able to have the same opportunities to benefit from the land resources, Cal Poly’s stakeholders need to develop the mind-set and tools to help us maintain and enhance these resources. This section describes several approaches available to help us.</p>

New Zealand's Search for Sustainability: Ideas for California Planning
Wack, Paul
2004-04-01T08:00:00Z
FOCUS: Journal of the City and Regional Planning Department (Cal Poly)
Article
New Zealand, or Aotearoa to the native Maori, is a small island nation of 4 million people and 47 million sheep, located across the Tasman Sea from Australia. The home of the Kiwi (an endangered bird, a popular fruit, and the friendly people) is about the size of Colorado, although the shape of the north and south islands would approximate the elongated length of California.
Much of New Zealand would remind us of Oregon and the Sierras with their majestic Southern Alps. Overall, New Zealand reminds me of California during the 1950’s, before urban sprawl kicked in with a vengeance. As a former British colony, New Zealand had followed the traditional Town and Country Planning model, until the early 1990’s when sustainability became a major interest to a wide range of national politicians and officials, planners, and citizens. Unlike the U.S., New Zealand has been very active in attempting to address global issues at both the national and local level, especially since the 1992 Earth Summit in Rio de Janeiro, Brazil.

FOCUS: Journal of the City and Regional Planning Department (Cal Poly)
Article
In this article Paul Wack offers us a reflection on two of the most important issues for the planning profession: climate change and the public’s short attention span. He starts by addressing a 1895 poem depicting an optimistic view of the future which the late musician John Denver used to recite during his concerts, and in which Paul finds much inspiration for his classes. The article also ties into the next one, titled “Hot Topic”, dealing with the same theme and originally published in the APA’s Planning magazine.

Sustainable Technology Park at California Polytechnic State University, San Luis Obispo: Handbook of Guidelines: Ecology meets Technology
Article
As with any building project, climate has an enormous impact on building and site energy and water consumption, the potential for on-site electrical power generation, indoor environmental quality in terms of thermal comfort and daylighting opportunities, and the creation of protected outdoor environments as extensions of interior spaces. In order to assess the site-climate design potential designers, users, and building owners need to consider issues revealed by quantitative, scientific data of existing conditions, qualitative regional or microclimatic principles that optimize building form, organization, and materials based on this understanding, and simulations of future design alternatives. This paper discusses the relevant questions and requisite data in considering the role of regional and local climate in the design of the research office buildings for the Technology Park on the Cal Poly campus in San Luis Obispo, California.

Augmentation of Free Surface Heat and Mass Transfer Due to Electrostatic Fields

Article
Experiments were conducted to measure heat transfer rates and mass transfer rates from a water surface in the presence of electrostatic fields of various strengths generated between the water surface and a wire grid above the surface.
Heat transfer rates were determined by the temperature decay after heating the test and control basins. Mass transfer rates were determined by measuring the water loss while holding the basins at fixed temperatures.
It was found that very little increase in transfer coefficients took place for voltages below an onset voltage which depended on atmospheric conditions and test geometry. The heat transfer coefficient increased for voltages above the onset voltage reaching factors of three to four times the natural rate. The mass transfer coefficient also increased similar amounts for voltages above the onset voltage. The functional dependence of the increased heat and mass transfer rates on grid voltage agreed with theory developed for heat transfer from plates without mass transfer. Mass transfer could be predicted using the analogy of heat and mass transfer, but heat transfer could not because of the unknown contribution of radiative transfer which was not independently monitored.

Article
Ultrasonic flow measurement technology has the potential to significantly improve flow measurement accuracy beyond that presently achieved. However, current applications fail to achieve theoretical accuracies because of turbulence effects on ultrasonic wave transit time. Herein, the ultrasonic flowmeter equation is reconsidered, where the effects of turbulent velocity and sound speed fluctuations are included. The result is an integral equation for the corresponding correlation functions. In this paper experimental velocity data are used to solve this integral equation analytically. As a result, some statistical characteristics of the turbulent flow are developed and can explain the limitations of measurement accuracy observed in applications.

Flow Excited Acoustic Resonance in a Deep Cavity: An Analytical Model
Durgin, William W.
Graf, Hans R.
1992-11-08T08:00:00Z
Proceedings of the Third International Symposium on Flow-Induced Vibrations and Noise: Anaheim, CA
Article
Flow past the opening of a deep cavity can excite and sustain longitudinal acoustic modes resulting in large pressure fluctuations and loud tone generation. An analytic model of the interaction of the free stream with the acoustic flow field using concentrated vortices in the shear layer is proposed. The model includes a computation of the power transferred by the traveling vortices to the acoustic oscillation in the cavity. Experimentally measured values for the vortex convection velocity and phase are used to enable calculation of the ensuing oscillation amplititude and frequency ratio. The radiated acoustic power is calculated using the model and compared to that found from the measured velocity field.
Agreement between the model and experiments is found to be good for both the single and double vortex modes near resonance and for values of Ur above the single vortex mode. The single vortex mode resonance, the greatest oscillation amplititude, occurs at Ur = 3.2 with only a single vortex in the cavity opening. The double vortex mode resonance occurs at Ur = 1.5 with two vortices in the cavity opening simultaneously. In between the modes, the predicted power is too small probably resulting from difficulties in computing the generated acoustic power from the measured velocity field in this region.

An analytical model was developed to simulate human arterial pulse wave propagation in major arteries. It was verified with an experimental model. The models investigated the effects of the peripheral vascular bed on pressure pulse morphology. The models revealed that the capillary bed in normal humans acts as a high resistance, low reflectance, boundary condition.

Article
High velocity flow past the junction of a side branch with a pipe can result in the excitation of depth-mode standing waves in the branch. The shear layer separating the main stream flow and the cavity provides coupling between the driving and the driven flow. Photographic evidence indicates that large scale vortex structures develop at the shear layer. The vortex formation process involves strongly non-linear instability of the shear layer and may be characterized as a non-linear fluid mechanical oscillator. The standing wave system formed in the cavity is essentially an acoustic wave system of nearly linear character. The principle interaction takes place through the excitation of a quarter wavelength standing wave in the cavity. Apparently, the shear layer oscillator drives the acoustic oscillator which, in turn, has the ability to drive the shear layer through a presently unknown feedback mechanism. The system exhibits bandwidth synchronization in that the shear layer frequency is captured by the depth-mode resonance of the cavity.

Vortex Flows: Presented at ASME Winter Annual Meeting: Chicago, IL
Article
Vortimeters consisting of vanes rotating about pipe axes are frequently used to indicate the swirl present in pump columns and feedlines from sumps and in piping networks. Since the design of such devices varies widely, the study described herein was undertaken to identify salient design parameters and to evaluate a device designed according to information available in the literature.
An apparatus which could produce known amounts of angular momentum in a pipeline was verified by direct measurement of axial and tangential velocity profiles. By using the assumption that a vortimeter, with vanes spanning only the rotational core, responded to an equivalent solid rotational core, an expression was developed relating the angular velocity to the angular momentum. Comparison of the angular velocity which the swirl generator should produce if angular momentum were conserved to that measured by the vortimeter showed excellent agreement.

Ultrasonic Beam Propagation in Turbulent Flow

Proceedings of the 2001 ASME Fluids Engineering Division Summer Meeting: New Orleans, LA
Article
A study was conducted to examine how a coherent sound burst, such as those used in an ultrasonic flowmeter, crosses a turbulent flow field. Many ultrasonic flowmeters use a time of flight method to determine the mean flow. This measurement method sends sound waves at some angle across a velocity field between two transducers, and the time required for the sound burst to cross this distance is measured on the order of nanoseconds. The system then reverses so that the sound wave burst is sent in the opposite direction. Knowing the distance traveled, the local average sound speed, and the back and forth travel times, the integrated velocity along the sound path can be computed. By using average values for distance and time, an average flowrate may be determined. To perform this analysis, data from several velocity fields were used to determine how a coherent sound burst would travel across the field. Comparisons of the infinitely thin case and the finite thickness case are performed. The study focused on using a modified ray trace method on a velocity field data set obtained using PIV.

Unsteady Flow in Vertical, Converging Tubes

Fluid Transients and Fluid-Structure Interaction: Presented at ASME Winter Annual Meeting: Atlanta, GA
Article
The discharge of liquids from vertical tubes with various contraction geometries was studied via the unsteady Bernoulli equation.
The temporal variations of the exit velocity and fluid level in the tube were found from the numerical integration of nonlinear
differential equations. Sudden, quadratic, and exponential contraction geometries were considered. For inlet to exit area ratios
greater than two, the flow initially accelerates to a maximum speed and then it decelerates for the geometries studied. The exponential contraction has the shortest discharge time. The solutions also reveal that the largest possible velocity and the shortest discharge time are achieved in a non-converging tube.

Measurement of the Nonsteady Flow Field in the Opening of a Resonating Cavity Excited by Grazing Flow
Graf, Hans R.
Durgin, William W.
1993-05-01T07:00:00Z
Journal of Fluids and Structures
Article
<p>Flow past the opening of a cavity can excite acoustic resonance. The periodic velocity field in the region of the cavity opening has been measured for various flow conditions and the vorticity distribution has been computed from the measured data using numerical differentiation. The results indicate that the shear layer rolls up into discreet vortices, which travel across the cavity opening. Two resonances were found. The first is characterized by a single vortex being present and results in the greatest amplitude. The second is characterized by the presence of two vortices which excite a distinct but lesser amplitude resonance. As the flow velocity changes, the position of these vortices shifts relative to the phase of the acoustic cycle. The timing of the interaction between the moving vortices and the acoustic particle velocity determines, to a large extent, the intensity of the excitation, and therefore also the oscillation amplitude. The measurements also indicate that the boundary layer upstream of the leading edge pulsates considerably.</p>

The Deconstruction of a Study: Toward More Effective Evaluation of Research Studies in Cognitive Social Psychology
Montelongo, Jose A.
2008-02-26T08:00:00Z
Article
Information literacy modules produced by academic libraries to facilitate the research process typically use the criteria of relevance, timeliness, reliability, coverage and accuracy to assess the various information resources undergraduate students use to write research reports. These same criteria are applied to the wide spectrum of research sources that may range from popular magazines to research journal articles.
In the field of Cognitive Social Psychology, many research questions necessitate the use of psycholinguistic stimuli (word lists, paired-associates, sentences, stories, etc.) as their treatments. This paper investigates the ability of information literacy modules based on the standards set forth by the Association of College and Research Libraries (ACRL) to assist students in evaluating empirical studies investigating social cognitive behavior.
A study of social balance schemas was deconstructed and analyzed. Using the evaluation module based on ACRL standards, this study was evaluated as relevant, reliable, authoritative, and accurate. Similarly positive assessments of the study have been reached by experts in the field of social cognitive psychology. However, the evaluation of the study using questions grounded in experimental methodology and a basic understanding of psychological theory and statistical methods proved to be contradictory. A new set of analytical questions for evaluating research studies using psycholinguistic materials was generated from the errors in the experimental study.

Change situations tell a story in which there is a change in a measurable quantity of a particular thing. Group word problems ask the solver to use combine members of the same classification before performing a mathematical calculation upon these. Compare situations require a student to complete mathematical calculations upon two or more things and to contrast their quantities for a conclusion. Restate word problems include both a relational statement between two or more things and a numerical value for expressing the relational statement in measurable terms. Vary situations are those where the relationship between two things is generalizable across other values of these things.
The basic premise of this article is that educators in the middle and upper elementary grades can use a modified version of the sentence completion task (fill-in-the blanks) to familiarize students with the various structures of word problems. By embedding the sentences comprising a word problem among unrelated sentences, teachers can challenge their students to a) find the sentences pertaining to the word problem; b) order these related sentences into a logical order with or without the aid of a graphic organizer; and c) solve the problem. With frequent exposure to this activity, students may learn the various word problem structures.

Article
Against a backdrop of compelling societal needs, graduates in science and engineering
now must master their disciplines <em>and</em> demonstrate a sophisticated level of cognitive, affective and social development. This has lead a number of national and international commissions on science and engineering to urge educators to re-think the way in which STEM disciplines are
taught. We have chosen to "repackage" a traditional undergraduate materials engineering curriculum in a form designed to promote the development of higher-order cognitive skills like self-directed learning and design. Classic metallurgy experiments have been converted to project-based learning experiences where students are put in the role of "designers" of problem solutions and faculty play the role of coaches. These include: designing, prototyping and marketing of a cast metal object; systems designing, building and testing of a fiber optic spectrometer; product improvement of a prosthetic device; evaluation of oxidation process for production; design and evaluation of a heat treatment process for roller bearings; and materials characterization of an everyday product. Projects were designed to leverage known relationships
within the educational psychology literature that enable deeper learning. Evaluation of 36
juniors in a project-based learning course (i.e., the test cohort) against a quasi-control group in
traditional engineering courses showed that the test cohort scored significantly higher on two motivation scales shown to be critical components in self-directed learning (p<0.001). The test cohort also reported a significantly higher use of peers as learning resources than the quasi-control group. Their motivation scores also correlate highly with self-reported comfort with several aspects of design, implying that their motivation contributes significantly to students' ability to effectively engage in the design process. In this paper, we present examples of the materials engineering projects that were designed and implemented, and the design features that enable them to promote the development of sophisticated cognitive functioning.

<p>Equipping engineering students with the skills and knowledge required to be successful global engineers in the 21st century is one of the primary objectives of undergraduate educators. Enabling students to practice self-directed learning, to find solutions to design problems that are sustainable and to recognize that they are part of a global community are just of few of our educational goals. Self-directed learning can define an individual’s ability to practice life-long learning. It places the responsibility on the individual to initiate and direct the learning process and can enable an individual to adapt to change. Project-based learning provides the contextual environment that makes learning exciting and relevant. It provides an opportunity for students to explore technical problems from a systems-level perspective and to develop an appreciation for the inter-connectedness of science and engineering principles. In Materials Engineering, the model of a tetrahedron is often invoked to illustrate the bottoms-up connectivity of the fundamental principles associated with a material’s processing, structure and properties, which must be optimized to reach a desired performance. In addition, a top-down tetrahedron can be envisioned with the need for sustainability guiding the balance between economic, societal and environmental factors, which also influence the choice of the optimum design solution for a project. For students to fully explore this paradigm, it is imperative that project-based learning experiences be integrated throughout their undergraduate education. This article will explore methodologies that we have adopted to implement project-based learning through our four year undergraduate curriculum. Significantly, our course evaluations indicate that students strongly feel that this is a better method for “learning” and believe that the projects provide a more realistic environment for applying the principles of engineering, science and mathematics towards solving practical problems.</p>

<p>Publishing online is an increasingly prevalent means for scholars to test their ideas. But what of its challenges? Focusing on an ill-fated Web site dedicated to the polemic French writer Louis-Ferdinand Céline, and on a proposed hypertextual edition of his most multilinear and multisequential work, this paper asks how to reconcile the need of academics with the bullheadedness of publishers who resist the renegotiation of copyright and the marketplace it (once) enabled.</p>

<p>How to engage students to reread Arthur Rimbaud’s 1886 poem “Mouvement” differently? What can they learn about the poem and in the process about themselves as readers of literature through its various versions and English language translations? Might rereading for difference hold pedagogical promise? How might a comparative study of the poem’s various versions in French and in English translation favor active reading and help students embrace the poem as differently meaningful because of its modernity?</p>

<p>Throughout the twentieth century activists in South Africa for the Afrikaans language struggled with, yet never resolved, the language/people, Afrikaans/Afrikaner issue, as Hermann Giliomee points out in his recent ‘biography’ of the Afrikaners (2003, 389). Was the Afrikaner community a racial or linguistic one? Was the push to promote Afrikaans subordinate to the entrenchment of a white supremacist government and ruling party? Was there a hegemonic or counter-hegemonic relationship between language and ethnicity? If the social identity of the Afrikaner was to be shaped by the acceptance of Afrikaans as a public language on equal footing with English, the creed that the language constitutes the entire people <em>(‘die taal is gans die volk’)</em> had to be race-blind.</p>

Urban Design and Conflicting City Images of Brazil: Rio de Janeiro and Curitiba
del Rio, Vicente

Cities
Article
<p>Imageability of places, cities and countries is strongly influenced by tourist and political portraits in the media. As human cognition relies on inferential perception and contrasting categories, marketing strategies exploit partial truths and conflicting city images to direct public perceptions. This article addresses the relationship between international perception, image building and urban design in the case of Brazil and the cities of Rio de Janeiro and Curitiba. Their contrasting images as exploited by the international media expose only partial truths. In fact, these images represent complementary development contradictions that co-exist in any major city today.</p>

Association of Collegiate Schools of Planning Conference Proceedings: Baltimore, MD
Article
<p>Through this paper we intend to raise some fundamental questions regarding urban design education at the undergraduate level, and to discuss possible pedagogical strategies. The discussion is fostered by the brief description of a recently developed and still evolving proposal to provide an area of concentration in urban design education at the undergraduate level within the College of Architecture and Environmental Design at the California Polytechnic University, San Luis Obispo, California. One of the starting points for our Cal Poly program development team - composed of faculty from the departments of Architecture, Landscape Architecture and City and Regional Planning - was to explore the ideal nature of an urban design education, to examine established urban design programs in the US to examine their theoretical and pedagogical underpinnings, and to some extent discuss and advance to a shared general definition of urban design. By facilitating this debate we will be obtaining specific critique and feedback regarding our program proposal, and will be contributing to the advance of urban design education in general. Awkwardly enough, while there seems to be an agreement on the growing importance of urban design to cities and daily life, we still have to reach for a common definition, a common body of theories, knowledge, and methods, and a common set of expectations.</p>

Advances in Accounting Behavioral Research
Article
<p>This paper reports the results of a study that was conducted to investigate the performance of senior-level business students as it pertains to recognizing certain clues or risk factors that are frequently associated with the misappropriation of entity assets. Based on three of the risk factors identified in SAS No. 82, an experiment was used to examine differences in performance based on academic major, fraud-specific knowledge, and certain experiences of the students. The primary contributions of this study are the discovery that: (1) an increasing number of risk factors; (2) knowledge accumulated in an accounting curriculum; (3) reading additional articles on the topic of employee theft; and (4) direct encounters with employee theft in the workplace were positively and significantly associated with recognizing an increased possibility that employee theft may be occurring. The results also indicate that neither employer-provided fraud training, nor part-time work experience, helped the subjects recognize an increased level of vulnerability of an organization to employee theft.</p>

Postmodernity and economic globalization
incite countries, regions, and cities to compete for investments, consumers, and resources. In aspiring for a new position in this global market, cities utilize new urban practices that lead them to rediscover and reinvent identities and traditions. In Rio de Janeiro, the mythical dimension of the South Zone is inseparably incorporated to its identity. In evaluating the history of the imagery linked to the beaches and the projects for the waterfront, one may observe a social construction of a reality that is marked by a continuous redesigning of symbols but also by a discontinuity in the history of urban interventions. Although tourism and marketing continually praise the waterfront as a fundamental factor in the image of the city, a continuous public management process never really existed. The city managers must understand the beaches, the waterfront, and development along the shoreline as important resources in a continuous process of social construction of a reality that should not only address their images as commodities but should treat them as inseparable from the city's daily public and social lives.

Article
How much of the original urban design of an area leads to its perceived qualities, to its public image, and to its recognition as a special place by its users? In this paper we present the preliminary results of a comparative study of residential areas in the city of Rio de Janeiro - Brazil that are highly regarded as special places by both their communities and the population at large. Our research tries to understand which aspects of the original design of these places still remain today and may be held responsible for their popular success, and which design fundamentals are common to all of them. We will comment on the first case-study in our research, the area called General Glicerio, a residential development of the late thirties.

Beyond Brasilia - Contemporary Urban Design in Brazil
del Rio, Vicente
2005-10-17T07:00:00Z
Proceedings of the 41st ISOCARP Congress: Bilbao, Spain
Article
<p>This paper is a brief discussion of a recent research on how Brazilian cities have been shaped from the late 1980s to the early 2000s through several case studies in different cities. After the disruption of the modernist paradigm, the demythification of Brasilia, and the redemocratization of the country in the 1980s, architecture and urbanism in Brazil were eager for new models with which to face urban development. On one side globalization and market forces dragged society towards an “entrepreneurial” and fragmented city of shopping centers, gated communities, private enclaves, and trendy and irrelevant architectural imagery. On the other side academia, intellectuals, community and social movements, and conscientious political leaders pushed toward another social order and to solutions that are more appropriate to the Brazilian social and cultural heritage. This duality is clearly reflected in urban landscapes throughout the country and reflects a constant tension between opposite realms: global-local, private-public, and the individual-collective. Urban design reflects this duality and the tensions that it generates in Brazilian cities, and it always results from public actions, either directly –through programs and projects by institutional agencies– or indirectly –through legislation, incentives, and other instruments set to control the market. Even illegal settlements and substandard housing result from political, economic, and social options at the governmental sphere, or simply from the lack of satisfactory institutional actions at national, regional, and local levels. Urban design seeks to shape the public realm, ensures its quality, and sets the stage for cultural, social and economic development. Findings of my research show how urban design can be regarded as a fundamental tool towards a pluralist and democratic city in Brazil, where three major trends in its practice were identified: a) late-modernism, b) re-utilization of the built environment, and c) social inclusion. This paper will briefly discuss some of the research findings in the hopes that it will be relevant to a better understanding of the role of urban design from an international perspective.</p>

Laser Doppler Anemometry for Flow Measurement
Durgin, William W.
Neale, Lawrence C.
1977-02-23T08:00:00Z
Proceedings of the Symposium on Flow Measurement in Open Channels and Closed Conduits: Gaithersburg, MD
Article
Laser doppler anemometers are non-invasive, linear, and inherently precise. Calibration, in the usual sense, is not necessary; length and frequency measurements suffice to establish velocity at a spatial point. Measurements were
made at points in the cross-sections of two square ducts containing water flow. The points were selected in conformance with a numerical integration scheme to be used for volumetric flow rate determination from the velocity measurements. The experiments were performed in a primary calibration facility at flows up to 1.25 m<sup>3</sup>/sec using ducts with sides 46 and 92 cm. The anemometer, operating in forward scatter differential mode with a 15 mw He Ne laser, was positioned with a special traversing frame. Windows in the ducts allowed transmission of the beams into the flow and reception of scattered light. Two grid patterns, 4 x 11 and 11 x 11, were used so that 44 and 121 velocities were measured for each test. A total of eight tests were conducted covering a Reynolds number range from 1.1 to 3.9 X 10<sup>8</sup>. After accounting for errors due to the discreet integration scheme of 0.61% and 0.13% for the 4 x 11 and 11 x 11 schemes, respectively, comparison with the calibration facility indicated extreme errors of +0.81/-0.16 and +0.84/-0.61. The major limitation of the set-up used was the time required to move the anemometer and obtain a new velocity value. It was pointed out that either better mechanical positioning or optical scanning could be employed to reduce the time required for a flow determination.

Crystals grown from special liquid solutions find important industrial applications. Most often the physics and chemistry of the growth processes are not well understood due to complex microscopic chemical and thermo-fluid phenomena. Microgravity could help elucidate these phenomena and allow the control of defect concentration and crystal size. We are proposing to study zeolites grown in silica solutions as a typical crystal growth system. By using macroscopic fluid dynamics, coupled with first-principle microscopic fluid physics and advanced particle simulations, we will study: (a) the effect of transport phenomena and nutrient flow under microgravity conditions along with (b) the nucleation process and (c) the microscopic crystal growth dynamics. The macroscopic model will account for the bulk fluid-crystal motions. The microscopic model will include multiple nutrient species and growth sites, and microscopic interactions during the nucleation and crystallization processes. The numerical results will be compared with data we obtained from terrestrial and space experiments.

This research effort is directed toward two primary scientific objectives: (1) to determine the gravitational effect on the measurement of nucleation and growth rates near a critical point and (2) to investigate the nucleation process in supercritical fluids to aid in the evaluation and development of existing theoretical models and practical applications. A nucleation pulse method will be employed for this investigation using a rapid expansion to a supersaturated state that is maintained for ≈ 1 ms followed by a rapid recompression to a less supersaturated state that effectively terminates nucleation while permitting growth to continue. Nucleation, which occurs during the initial supersaturated state, is decoupled from growth by producing rapid pressure changes. Thermodynamic analysis, condensation modeling, apparatus design, and optical diagnostic design necessary for the initiation of a theoretical and experimental investigation of naphthalene nucleation from supercritical C0<sub>2</sub> have been completed.

The focus of this ground-based program is the study of film condensation phenomena under variable, reduced-gravity conditions. Experimental tests, combined with numerical modeling, are employed to gain an improved understanding of the fundamental fluid physics responsible for condensate film growth, film instability and the resulting interfacial motion under variable gravity, and the corresponding implications for heat transfer. There has been relatively little research on the mechanisms operative at the film interface between condensed liquid and its vapor under reduced gravity conditions. Of particular interest are the stability characteristics of the condensate layer, and how they differ from those of films of comparable scale in the absence of condensation.

Worcester Polytechnic Institute's first payload of spaceflight experiments flew aboard Columbia, STS-40, during June of 1991 and culminated eight years of work by students and faculty. The Get Away Special (GAS) payload was installed on the GAS bridge assembly at the aft end of the cargo bay behind the Spacelab Life Sciences (SLS-l) laboratory. The experiments were turned on by astronaut signal after reaching orbit and then functioned for 72 hours. Environmental and experimental measurements were recorded on three cassette tapes which, together with zeolite crystals grown on orbit, formed the basis of subsequent analyses.
The experiments were developed over a number of years by undergraduate students meeting their project requirements for graduation. The experiments included zeolite crystal growth, fluid behavior, and microgravity acceleration measurement in addition to environmental data acquisition. Preparation also included structural design, thermal design, payload integration, and experiment control.
All of the experiments functioned on orbit and the payload system performed within design estimates.

Direct Measurement of Circulation Using Ultrasound

Experiments in Fluids
Article
<p>Ultrasound time-of-flight methods employing counter-propagating ultrasonic pulses are utilized for the direct measurement of circulation in vortical flows. Two schemes are described here which involve either a single straight path or a closed path. Both techniques are shown to result in time differences, between the counter-propagating pulses around the path, linearly proportional to the circulation enclosed by the ultrasound path. The ultrasound methods of circulation measurement do not require calibration constants and can be non-invasive. The reliability of the closed path ultrasound method was assessed by comparing the measured circulation values with those calculated from the lift measurements of a NACA 0012 airfoil. Two examples are also presented where the closed path ultrasound method has been applied to the flow over a delta wing and a free-surface vortex in a cylindrical tank.</p>

Experimental Investigation of the Travel-time Variance of an Acoustic Wave Propagating Through The Grid-generated Turbulence

An experimental technique for the investigation of the behaviour of acoustic wave propagation through a turbulent medium is discussed. The present study utilizes the ultrasonic travel-time technique to diagnose a grid-generated turbulence. Travel-time variance is studied versus mean flow velocity, travel distance and outer turbulence scale. The effect of thermal fluctuations, which result in fluctuations of sound speed, is studied using a heated-grid experiment. Experimental data obtained using ultrasonic technique confirm numerical and theoretical predictions of nonlinear increase of the travel-time variance with propagation distance, which could be connected to the occurrence of caustics. The effect of turbulent intensity on the travel-time variance and appearance of caustics is studied. It is demonstrated experimentally that the higher turbulence intensity leads to the shorter distance, at which the first caustic occurs. The probability density for caustics appearance is analyzed against the measured wave amplitude fluctuations. The analysis reveals that the region of high-amplitude fluctuations corresponds to the region where the probability of formation of random caustics differs from zero. Experimental results are in very good agreement with theoretical and numerical predictions.

Article
In 1970 WPI completely revised its traditional approach to engineering education. The resulting program, the WPI Plan, emphasized the use of projects as a distinctive process for achieving educational goals. Every student, as a degree requirement, had to successfully complete two major projects: one in a student's major field, the Major Qualifying Project (MQP) and the second, the Interactive Qualifying Project (IQP), which related science and technology to societal issues.
The IQP's related to the restoration of the WWII Avenger at Mayocraft, Inc. for the Collings Foundation in Stow, Massachusetts enabled the students working with the authors as advisors to apply classroom learning to real world problems including the effects of WWII technology on society over the last half century. Issues ranging from the location of an aircraft for restoration, costs, location or manufacture of parts, collection and verification of data, and whether the final project should be a flying or static display were among the many factors evaluated by the student project teams and incorporated into their final oral and written reports. Although not a part of the projects of the students it is of interest that the Avenger is flying and its restoration project has been made known to the public via the Discovery Channel.
Post project analysis includes student evaluation of the program and faculty as well as periodic reviews of the IQP's by faculty committees. Abstracts of the projects are published. Continuous evaluation of all IQP's makes sure they integrate into a physical reality the social, political, and humanistic dimensions of a technical world.

Proceedings of the 1986 Symposium on Measuring and Metering of Unsteady Flows: Anaheim, CA
Article
An electromagnetic flowmeter was developed to measure transient flows with a frequency response of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics of a commercially available electromagnetic flowmeter normally used for steady-state operation. Use of the commercially available flowmeter body, which includes the magnetic coils, core, and signal electrodes, provided a relatively economical means of fabricating the transient flowmeter. A transient flow calibration facility consisting of a free-falling water column was also designed and built. Results of the calibrations are presented and show that the flowmeter can accurately measure transient flows up to the maximum observed acceleration of approximately 1 g.

AIS curriculum
<p>The ability to understand, document, and suggest improvements for a business process is an important skill for an accounting student for the following reasons: (1) efficient business processes give businesses a competitive advantage; (2) business process analysis provides auditors with an assessment of business risk; and (3) successful enterprise resource planning implementation depends on understanding and improving existing business processes. It is suggested that students be introduced to process mapping and scripting in an accounting information systems (AIS) course to facilitate their understanding of business processes and help them visualize the interaction between functional areas. The specifics of process mapping are covered and advantages of incorporating process mapping into the AIS curriculum discussed. It is also proposed that scripting, which is used to facilitate configuration, testing of ERP software and communication between the accountant and the programmer, be included in the AIS course. Finally, suggestions for classroom activities are included.</p>

Review of Irving Gill and the Architecture of Reform by Thomas S. Hines
Giberti, Bruno
2003-03-01T08:00:00Z
Journal of the Society of Architectural Historians
Article
<p>In a 1916 essay that was probably his most important written statement, Irving Gill railed against contemporary historicism and argued for a return to origins: "the straight line, the arch, the cube and the circle." His ideal was not the primitive hut but an equally convincing trope that he called "the stone in the meadow." This phrase implied a method by which the rational was to be brought into an intimate relationship with the organic: "We should build our house simple, plain and substantial as a boulder, then leave the ornamentation of it to Nature."</p>
