The idea behind a Sensory Rooms is to create a place to calm the students and to expose ...
Experimental Building Demonstration Model With Viscous Fluid Dampers, 2016 California Polytechnic State University, San Luis Obispo
Experimental Building Demonstration Model With Viscous Fluid Dampers, Blake Thomas Reeve, Brianna Jean Kufa, Aden Malek Stepanians, Sophie Carmion Ratkovich
The Architectural Engineering major places a heavy emphasis on structural dynamics and the role of wind and seismic loading in building analysis and design. Buildings of high importance that are critical to community function, such as hospitals, often utilize supplemental damping devices like supplemental viscous fluid dampers or base isolators to reduce the overall demands on the structural system. The design and analysis of these dampers are typically not taught at the undergraduate level, and is frequently performed by mechanical engineers, in lieu of structural engineers.
To better understand and research building behavior with supplemental damping devices, our multi-disciplinary team ...
Inclusive Lectern, 2016 California Polytechnic State University, San Luis Obispo
Inclusive Lectern, Trent Canales, Sean Day, Dylan Sigley, Stephen Sippel
A lectern is an essential piece of equipment for almost all speeches and presentations. They come in many forms and range in degree of professionalism depending on the occasion. Lecterns not only hold a presenter’s notes, a microphone, or other presentation aids, they provide a structure for a presenter that can bolster their confidence during a presentation. As such, it is important that all presenters have a lectern available to them. Unfortunately this is not always the case due to lectern accessibility limitations. This problem inspired the Cal Poly Disability Resource Center to request a lectern that satisfies the ...
Efficiency Testing Of An Electronic Speed Controller, 2016 California Polytechnic State University, San Luis Obispo
Efficiency Testing Of An Electronic Speed Controller, Grace Cowell, Matthew Hudson, Marcus Pereira
This project required the development of a rig that could experimentally determine the efficiency of an Electronic Speed Controller (ESC). The selected design focuses on measuring the losses due to heat from the device and comparing this to its input power. The selected design is a flow rig that utilizes the heat equation q=ṁcpΔT. The rig provides a steady state measurement of the ESC heat output by passing a known mass flow rate of air across the ESC and measuring the temperature difference. It uses a flowmeter to determine ṁ, thermocouples to determine ΔT, and a table lookup to ...
Compliant Air Skates, An Experiment, 2016 California Polytechnic State University, San Luis Obispo
Compliant Air Skates, An Experiment, Samuel Feldtkeller, Cody Anderson, Kevin Daily, Eliana Stefani
There is currently a gap in the market of train levitation systems: wheeled trains and MagLev trains exist, but none utilize the low friction and high efficiency aspect of trains levitated by air skates. An air skate, is an air bearing that uses a pressure difference along its annular body to create a thin flow of air which is strong enough to "levitate" the weight of the skate. We have designed a compliant air skate that can glide over 0.04[in] defects in surfaces without touching down. After having made compliant skirts out of fiberglass and silicone, our setup ...

Walker Tray, Marlene Troncoso, Judy Lantaca, Miriam Krage, Claire Francis
Sean is an individual with Cerebral Palsy, a disability that affects one's balance, muscle tone, muscular coordination, posture and control. Sean utilizes a walker to aid in maintaining his balance and muscular coordination when ambulating. This enables him to walk independently and leads to improved muscle strength and coordination. When walking, Sean places both hands on the walker to maintain balance and thus the ability to walk and carry items at the same time is compromised. Sean would like to be able to transport items while in use of his walker. The goals of this senior project design are ...

Numerical Investigation Of Full Scale Thunderstorm Downbursts: A Parametric Study And Comparison To Meteorological Model, 2016 The University of Western Ontario
Numerical Investigation Of Full Scale Thunderstorm Downbursts: A Parametric Study And Comparison To Meteorological Model, Christopher Oreskovic
Electronic Thesis and Dissertation Repository
A series of Large Eddy Simulations using an atmospheric meteorological cloud model have been used to investigate the important geometric and thermal parameters that influence a thunderstorm downburst outflow, as it pertains specifically to the idealized cooling source model. A separate set of Large Eddy Simulations make use of the same idealized cooling source model, in a realistic atmospheric base state using real field sounding data, in an attempt to make a quantifiable comparison to a downburst from a full cloud simulation. Randomness has been added to the cooling source forcing function to mimic the thermal variation in a real ...
