Electroluminescent (El) Wire Soldering Solution, Sean Mitchell

Industrial and Manufacturing Engineering

Electroluminescent (EL) wire is a unique kind of wire because it glows when attached to a power source. EL wire has many applications, both creative and practical. For example: Burning Man enthusiasts like to adorn their clothing with the flexible wire, and emergency responders use it to mark off accidents on the road at night. What makes EL wire glow is the electrical reactions between its copper wires and phosphor coating. The problem with this wire, however, is that it is very difficult to connect it to a battery. This is due to the wire’s structure. Beneath its protective plastic …

Determining A Method For Rendering Low Cost Cdse(Zns) Core(Shell) Quantum Dots Aqueous Soluble Via Amphiphilic Polymer Wrapping, Patrick Mcbride

Materials Engineering

Herein is described the procedure of two amphiphilic polymer wrapping techniques that may be employed for obtaining aqueous soluble quantum dots (QDs) for use in biological fluorescent imaging applications. The advent of QDs has led to new nanoscale fluorescent materials that exhibit unparalleled quantum yields (QYs), high resistance to photobleaching, tunable emissions, and
absorption over a large optical range. However, the QD synthesis employed here at Cal Poly to obtain bright, photostable CdSe(ZnS) core(shell) QDs involves the use of organic solvents and surfactants, leading to hydrophobic QDs. Since all of biology relies on aqueous solubility, this hydrophobicity creates a major …

Imu Integration To The Cal Poly Spacecraft Attitude Dynamics Simulator Power System, Wayland Chan

Electrical Engineering

The Cal Poly Spacecraft Attitude Dynamics Simulator mimics the rotation dynamics of a spacecraft in orbit and acts as a test bed for spacecraft attitude control system development and demonstration. Prior to this project, the simulator measured its attitude dynamics from a total of seven sensors mounted on to the platform, including three micro-electromechanical system (MEMs) gyroscopes, and four motor encoders. This project entails the installation of an LN-200 high performance gyroscope, which will provide a greater measure of accuracy. The goal of this project is to design a power circuit that will integrate the LN-200 inertial measurement unit onto …

Mp3 Player System Design, Eric Wu

Electrical Engineering

The purpose of this project is to design and build a portable audio player that reads music files off an SD card, decodes the music file and outputs the music through a headphone jack.  A microcontroller running FreeRTOS will facilitate the data transfer between an SD card and the decoding chip.  The decoded audio will then be sent to a high-end DAC chip that outputs the sound.

Wireless Sensor Network For Energy And Environmental Monitoring: Helping Old Buildings Go Green, Jacob Power

Electrical Engineering

Today, the rising cost of energy and social trend of “going green” has put increasing pressure on commercial property owners to improve the efficiency of their investments.  There is good reason for this, too.  In the State of California, office buildings represent the single largest user of energy in the commercial sector.  This project consisted of the design, implementation, construction, testing, and deployment of a wireless sensor network for energy and environmental monitoring in retrofit commercial office installations.  The analyzed data generated by this system can be used by building management and owners to identify areas of inefficiency within the …

A Speech Of Defense: Obama's Apologia For Himself And The Reverend Jeremiah Wright, Trevor Adams Hogan

Communication Studies

During the 2008 Presidential Election, Democratic candidate Barack Obama faced political controversy surrounding his pastor, the Reverend Jeremiah Wright. Videos surfaced on ABC News of Wright making racist and anti-American statements during his sermons. Obama who had strong ties to Wright over many years was criticized for his relationship with Wright. Because of their connection, Obama's political success was tied to his association with Wright. In a speech titled "A More Perfect Union", Obama makes an Apologia or defense for himself, and the Reverend Jeremiah Wright. Addressing the Kategoria or attacks made against himself and Wright, Obama uses the speech …

The Effects Of Message Framing And Denotative Specificity On Students' Opinions Of The Hpv Vaccination, Arielle Tenaya Marie Gout, Katherine Marie Kays

Communication Studies

The purpose of our project is to use various persuasive techniques in order to determine the most effective method to persuade students about the HPV vaccination and the negative effects of the HPV virus. An important component of public health message design is determining the most effective types of messages for a particular audience. The results of this study are intended to be an aid to the creators of health messages regarding HPV and the HPV vaccination, with the ultimate goal of increasing the effectiveness of public health messages to adolescents in regards to these issues.

The Design And Manufacture Of A Microfluidic Reactor For Synthesis Of Cadmium Selenide Quantum Dots Using Silicon And Glass Substrates, Peter Gonsalves

Materials Engineering

A microfluidic reactor for synthesizing cadmium selenide (CdSe) quantum dots (QDs) was synthesized out of silicon and Pyrex glass. Microfabrication techniques were used to etch the channels into the silicon wafer. Holes were wet-drilled into Pyrex glass using a diamond-tip drill bit. The Pyrex wafer was aligned to the etched silicon wafer and both were anodically bonded to complete the microfluidic reactor. Conditions for anodic bonding were created by exposing the stacked substrates to 300V at ~350^oC under 5.46N of force.  Bulk CdSe solution was mixed at room temperature and treated as a single injection. The syringe containing …

Faking Altruism: The True Nature Of Giving, Kristina L. Barker

Communication Studies

I want to see if students are capable of donating to charities. I have picked the American Red Cross to donate to and in support of helping the disaster in Japan. This is a huge effort publicly and students have seen the destruction on a daily basis. I want to see how much students are willing to donate and if different selling strategies make a difference on donations. I will be promoting sunglasses as a gift incentive for donations, with each pair raising $3.60 towards relief efforts. I will be selling the incentives in-group settings and to individual students on …

The Effect Of Processing Parameters And Methylcellulose On Texture And Consumer Acceptability Of A Non-Melting Dairy Protein Gel, Joshua Goldman

Master's Theses

The overall goal was to understand the capabilities of a dairy based meat alternative.  This was done in three phases: 1) the production of a dairy protein gel as a base for a dairy based meat alternative, 2) texturization of the dairy protein gel base to produce a nugget like texture, and 3) a consumer test to determine the acceptability of the dairy based nugget compared to meat and meat alternatives on the market.

For phase I, a dairy protein gel base was tested to understand the textural attributes.  Milk to whey percentages and level of acidification were examined to …
