The objective of this analysis is to outline the code defined requirements and to confirm the minimum level of safety from fire is attained. Analyzed in the report are the design requirements prescribed in the adopted building and life safety codes, and the performance of the prescribed design. The prescriptive review addresses the building construction in regards to fire protection, the means of egress, the water‐based fire suppression system, and the fire alarm system. The performance review incorporates the goals and objectives defined by the Life Safety Code, a performance criteria that establishes tenability limits that must not be exceeded, the selection of three realistic and conservative fire scenarios with the potential to affect a large population of occupants, and an analysis of one fire scenario using engineering empirical calculations and computer‐based models to determine the effectiveness of the building fire protection systems.

The prescriptive design satisfies the code requirements; however, there are special situations, regarding the fire sprinkler system, that are not incorporated in the codes. For instance, the Planetarium dome projection screen’s impact on the fire sprinkler system’s activation time and water delivery to a hazard below the screen. Also, the lack of fire sprinkler protection below the telescopic seating system in the auditorium. Both of these applications require further analysis to better determine an adequate solution. The Lobby fire scenario analyzed estimates the building occupants will be unable to safely evacuate the building prior to being exposed to fire effects, more specifically diminished visibility and untenable temperatures. Possible solutions are recommended, but further analysis is required.

On-Sight Shifting at the Cryogenic Underground Observatory for Rare Events http://digitalcommons.calpoly.edu/physsp/153 http://digitalcommons.calpoly.edu/physsp/153 Thu, 06 Jul 2017 13:33:30 PDT During the summer of 2016, four Cal Poly students traveled to Assergi, Italy to contribute to the CUORE collaboration which is in search of a rare process called neutrinoless double beta decay. If detected, neutrinoless double beta decay will make break throughs in particle and nuclear physics, and will be the first observation of lepton number violation. The Cal Poly students provided on-sight shifting support during the installation phase of the project. This is a breakdown of the physics behind CUORE and Cal Poly's contribution.

Wong Taft Community College- New Student Center- Fire and Life Safety Analysis http://digitalcommons.calpoly.edu/fpe_rpt/85 http://digitalcommons.calpoly.edu/fpe_rpt/85 Fri, 30 Jun 2017 12:33:21 PDT The following report is a fire and life safety investigation into a new facility. The planned facility is a new Student Center at Taft Community College. The prescriptive requirements as set forth by the most up to date codes and standards chosen for the project are met. The building has been properly classified with respect to occupancy and construction type. Appropriate design for interior partitions and exterior walls have been identified. Interior finish requirements are elaborated so that adherence to these guidelines is made clear. The fire sprinkler system has an adequate supply of water from the municipal water supply alone to meet the calculated demand of the design area. A fire alarm system is proposed, but the proposed design does not make full use of the benefits of such a system due to reliance on fire sprinklers as a primary means of automatic detection. A third fire system proposed is a kitchen fire suppression system which will be dependent upon the competencies of the installing contractor in meeting the system manufacturer guidelines. Egress components are adequately sized and arranged, and occupant densities throughout the proposed floor plan allow for the fastest occupant movement based on the referenced literature. A performance based analysis has been conducted. Tenability was addressed with regards to visibility, exposure to carbon monoxide, temperature, and flashover conditions. Two design fire scenarios from the 2015 NFPA 101: Life Safety Code were chosen. The first involved Design Fire Scenario 1, which was modeled as a trash bag fire in an office. Results of this study found that the ASET exceeded RSET. ASET was set by tenability criteria for visibility while RSET was found using hydraulic calculation methods for the compartment where the fire was located. The second fire scenario involved Design Fire Scenario 6, which was modeled by burning bookcases located in a bookstore. ASET exceeded RSET for this study as well. ASET was set by visibility criteria while RSET was set by a full building egress time calculation based on hydraulic calculation methods. Recommendations for improving life safety at the Student Center include: (1) monitoring special events to ensure that neither decorations nor implements impede the means of egress or introduce materials which present a severe fire hazard; (2) resizing an exit within the Bookstore to match a second exit so that occupants can clearly identify this exit as an alternate means of egress; (3) monitoring for any changes in how areas in the Student Center are used to ensure adequacy of exits and egress components; (4) Adding redundancy for the fire sprinkler water flow switch to fire alarm monitor module connection.

This system will run off of DC power supplied by the solar panels connected to the DC House. This project tested and explored the group’s abilities to design and implement a full system run off of 48V DC. By installing this system it will greatly improve the ease for students to work at the SEF beyond daylight hours. The system will allow continuous dull lighting and will switch to full brightness once a person is detected. This feature goes along with the ideals of the DC House, saving energy. This project helped to show the capabilities of a DC system and can impact the lives of those in communities with no access to an AC grid. The results of this system were not as successful as planned. The wiring within the junction boxes proved to be quite tricky so the system does not work at its full potential, however this does lead to further improvements by students to come.

Light Sensing Automated Blinds http://digitalcommons.calpoly.edu/eesp/398 http://digitalcommons.calpoly.edu/eesp/398 Thu, 29 Jun 2017 16:51:14 PDT This project is solving the problem of wasted energy within buildings and homes, because currently the lights turned on inside building do not utilize natural, ambient light from the sun. Rather than having unnecessary light from a light source, the automated light sensing smart blinds can sense the amount of light outside the window and in the room, and then adjust the angle of the blinds to save energy by utilizing the available outdoor light. This way, the light source will not be running at maximum power output while there is excess light coming through the window. This project aims to design and construct the light sensing blinds to achieve the aforementioned goals. Hardware test results from this project demonstrate the capabilities of the smart blind system to measure ambient light inside the room and outside the window, to adjust the angle of each of the blinds on the window, and to change the desired brightness of the room.

Auxiliary Power System http://digitalcommons.calpoly.edu/eesp/397 http://digitalcommons.calpoly.edu/eesp/397 Thu, 29 Jun 2017 16:51:09 PDT The main objective for this project is to design and build a prototype for an all-electric SUV for the start-up company, Sharpell Technologies. This vehicle will comprise of the following configurations: auxiliary power system (APS), battery management system, battery pack wiring, CAN bus system, DC-DC charging converter, DC/DC auxiliary converter, instrument cluster, and motor controller/inverter. Each car configuration is a project assigned to a 2-4 student team; in total, eight EE senior projects and one ME project is produced. New lightweight batteries are also in the process of being developed to provide a viable electric source for the car. A mobile application, used by Internet of Things, will allow the user to check one’s vehicle at any time of the day. The complete prototype is expected in 2020. Our section of this project is to design and implement the Auxiliary Power System (APS) for this vehicle. To complete this project the group will follow a provided structure to finish within the three allotted quarters. These steps include receiving the project requirements for Sharpell Technologies, creating a test plan, implementing a project design, ordering the parts and developing the product, integrating and testing the components and then discussing our results and possible shortcomings.

Wax Bee Gone: A Safe, Effective Solution to Ear Wax Removal http://digitalcommons.calpoly.edu/eesp/396 http://digitalcommons.calpoly.edu/eesp/396 Thu, 29 Jun 2017 16:51:06 PDT This project sought to combine conventional methods such as scraping and water pressure to removal ear wax, but with electronic automation to removal the potential for human error as much as possible. Through the use of a 9V battery, and Arduino microcontroller, DC motors, and other circuitry, this project has developed a prototype for a device that can properly remove ear wax without any discomfort or risk to the user. Much of this project involved learning how to properly manipulate and provide the necessary power requirements DC motors from an Arduino and a 9V battery. Additionally, creating a 3D printed shell to house all the components in a watertight case was one of the more difficult parts of the project. This device can be used by any age group or level of experience. From our empirical data this product satisfies the need that was not fulfilled when the project began.
