Electrical Engineering
The micro hydropower project strives to meet the needs of a specific village in northern Thailand in partnership with Engineers Without Borders. Specifically, the electrical side of the system must be designed to convert the mechanical power of a flowing river that is turning a turbine into sustainable and dependable power. Currently available hydropower systems will be considered, analyzed, and tailored to suit the specific needs of the community in need. The system to be designed will be flexible enough to demonstrate proof-of-concept with the limited maximum generable power in lab while having the ability to be easily scaled for …

Organic Solar Cells Based On High Dielectric Constant Materials: An Approach To Increase Efficiency,
2013
Western Michigan University
Organic Solar Cells Based On High Dielectric Constant Materials: An Approach To Increase Efficiency, Khalil Jumah Tawfiq Hamam
Dissertations
The efficiency of organic solar cells still lags behind inorganic solar cells due to their low dielectric constant which results in a weakly screened columbic attraction between the photogenerated electron-hole system, therefore the probability of charge separating is low. Having an organic material with a high dielectric constant could be the solution to get separated charges or at least weakly bounded electron-hole pairs. Therefore, high dielectric constant materials have been investigated and studied by measuring modified metal-phthalocyanine (MePc) and polyaniline in pellets and thin films. The dielectric constant was investigated as a function of temperature and frequency in the range …

The Cal Poly Heating Ventilation and Air Conditioning (HVAC) Department was donated a fume hood so that it could be used for educational purposes in the lab. The fume hood was not fully set up and only ran in a constant volume mode; the fan ran at full speed with no feedback to reduce air flow. A fume hood can be opened or closed using the sash; air flowing through the sash opening must always be above a certain speed. As the sash is closed the opening grows smaller and the speed of the air increases. Two additional modes of …

Guidance System, Kayaking For The Visually Impaired, D. Ryan Kirtland, Ryan Phife, William Gardner, Amy Johnson
Biomedical Engineering
Quality Life Plus is working with Team River Runner to develop an assistive guidance system for veterans who want to remain active by kayaking, after sustaining an injury that impairs vision. This system allows these veterans to complete a slalom speed race independent of a personal guide in the water. The system incorporates 3 stations that each contain a speaker connected to a microcontroller system covered by a Pelican Case on a custom made buoy. During the slalom race, a kayaker will travel from shore towards buoy #1 as it omits sound from the speaker. As the kayaker moves around …
Design, Fabrication, And Testing Of An Emr Based Orbital Debris Impact Testing Platform,

Design, Fabrication, And Testing Of An Emr Based Orbital Debris Impact Testing Platform, Jeffrey J. Maniglia Jr.
Master's Theses
This paper describes the changes made from Cal Poly’s initial railgun system, the Mk. 1 railgun, to the Mk. 1.1 system, as well as the design, fabrication, and testing of a newer and larger Mk. 2 railgun system. The Mk. 1.1 system is developed as a more efficient alteration of the original Mk. 1 system, but is found to be defective due to hardware deficiencies and failure, as well as unforeseen efficiency losses. A Mk. 2 system is developed and built around donated hardware from the Naval Postgraduate School. The Mk. 2 system strove to implement an efficient, augmented, electromagnetic …

Training Future Designers: A Study On The Role Of Physical Models, Vimal Viswanathan, Julie Linsey
Faculty Publications, Mechanical Engineering
Physical Models in Engineering Education: Making Tomorrow’s Designers Creative Innovation and creativity are two essential qualities for tomorrow’s designers. In order to nurture these skills in designers, our engineering curricula need to include more hands-on training. In recent times, many engineering educators have recognized the importance of hands-on training in engineering curriculum. Allowing students to build and test their own physical models and learn from their mistakes can be a very effective way of teaching. Recent studies have shown that physical models play a very important role in design innovation and creativity. Building and testing such models can lead designers …

Mechanical Engineering
The Architectural Engineering Department at California Polytechnic State University, San Luis Obispo, owns and operates a single-axis earthquake shake table that previously was only capable of basic wave motion. After implementing a computer based interface to the existing system, Mechanical Engineering student seniors were able to create control algorithms that can take existing or user created acceleration data from earthquakes as well as any user defined position data to be accurately run on the earthquake shake table.

Experimental Assessment Of The Impact Of Asymptomatic Gas Emboli On The Vessel Wall, Linxia Gu, Eric L. Cutler
Department of Mechanical and Materials Engineering: Faculty Publications
Quantitative evaluation of shear stress in the vessel wall due to the presence of asymptomatic gas emboli is lacking. The goal of this work was to assess the impact of chronic asymptomatic gas emboli on the risk of atherosclerosis through a custom-built cardiovascular flow simulator. Gas bubbles were created by forced air from a syringe pump. The influences of embolism injection rate, pulse rate, and time-averaged flow rate on the wall mean shear stress were investigated at resting and elevated heart rate conditions. The recorded pressure and volumetric flow rate from 24 experimental settings with four repetitions each were used …
Thickness-Shear And Thickness-Twist Vibrations Of Circular At-Cut Quartz Resonators,

Thickness-Shear And Thickness-Twist Vibrations Of Circular At-Cut Quartz Resonators, Huijing He, Jiashi Yang, Qing Jiang
Department of Mechanical and Materials Engineering: Faculty Publications
Exact solutions for free vibration frequencies and modes are obtained for thickness-shear and thickness-twist vibrations of unelectroded circular AT-cut quartz plates governed by the two-dimensional scalar differential equation derived by Tiersten and Smythe. Comparisons are made with experimental results and the widely-used perturbation solution by Tiersten and Smythe under the assumption of weak in-plane anisotropy. Our solution is found to be much closer to the experimental results than the perturbation solution . For the frequency of the fundamental thickness- shear mode, the error of the perturbation method is 0.4549%, significant in resonator applications.
