- Description:
- Biomass is currently being researched as an alternative to fossil fuels because it does not have a finite supply. Biomass refers to organic matter such as wood, agricultural products, solid waste and natural gas that all contain precursors to high energy molecules. A challenge in using biomass as a fuel is that large numbers of oxygen atoms must be removed to increase the overall energy density. Deoxydehydration (DODH) is the name of the process that converts vicinal diols into alkenes. When DODH reactions are catalyzed, the reactions may be carried out in the presence of a metal oxide catalyst and reductant. In the current work, a vanadium complex was synthesized and adsorbed onto a silica support in order to form a heterogeneous catalyst. Several vanadium to silica ratios were synthesized and tested for DODH catalysis. Initial studies investigated conversion of styrene glycol into styrene. Catalysts synthesized at higher temperatures with higher vanadium:silica ratios were more effective for converting styrene glycol into styrene. Properties of supported catalysts are not fully understood and supported catalysts have not been widely studied for DODH reactions. This experiment demonstrates that supported catalysts are effective catalysts for DODH reactions. Extensions of the work will tailor catalysts for higher product yields and direct biomass conversion.

- Description:
- Unmanned Aerial Vehicles (UAVs) are aircrafts that are either controlled remotely by a human from a ground station or by an on board computer. There are various types of UAVs such as fixed wing drones as well as quadcopters and hexacopters, all of which use rotating blades. Originally, drones were used in areas deemed too dangerous for humans with exclusive applications in the military sector, but recent enthusiasm has led to an expansion into commercial, scientific and recreational areas. The goal is to embellish a drone with a Collision Avoidance System (CAS). Such a system uses ultrasonic sensors to detect potential objects that are in the flight path of the aircraft. It then measures and displays the distance between hazards and the UAV. The drone also records live video footage, with its camera, which is sent to goggles or a display. The skills applied to the project include learning how to solder, wire, read blueprints, use mechanical tools as well as the methodology of assembling, building, and programming drones. To accomplish this, three sensors are placed strategically on the front, rear and bottom of the UAV. These sensors are connected to an Arduino (a single-board microcomputer) that is coded to send the data to the ground station. At the station, another microcomputer is connected to a radio receiver. This receiver collects specific information and displays them on an LCD screen.

- Description:
- Modern day technology's consistently fast development is no longer a surprise to the users and consumers of it. The sheer speed at which technology develops has numbed citizens' to its continued improvements, creating an environment where society only feels awe when its development becomes gradual. Most users often overlook a crucial aspect of the technology they make use of: its ability to manipulate data in some manner. Regardless of the industry in which technology is being used, data is almost always a key factor and is much more precious than everyday users believe it to be. Data hiding and encryption is a key function enveloped within any technology used to process data. My design project is aimed to provide a live simulation of how specific data that is useful to a party would need to be transferred to ensure security and integrity. It utilizes a sonar to acquire the distance of an object in its perimeter, a microcontroller unit (MCU) to process this data anonymously, and a Field Programmable Gate Array (FPGA) unit with an embedded microprocessor to retrieve this data and encrypt it so that it is not easily accessible to anyone. The only way to access this data is to have a specific key in one's possession. This simulation offers users a hands-on understanding of how precious data is processed during communication of interested parties.

- Description:
- As the demand for computational power increases, the need to develop cost efficient methods for computing is constantly rising. To help solve this issue, our research is dedicated towards developing low power computational technology while being a cost-efficient solution compared to other resources. The project is aimed towards using Field Programmable Gate Array (FPGA) platforms that can be reconfigured and applied for use in image processing, data mining, and medical applications. The objective is to implement the maximum units of soft-core processors (Micro-Blaze) efficiently on a single FPGA chip while using the minimum amount of resources. The process for testing was performed using Discrete Fourier Transform (DFT). The next objective is to design communication interfaces to connect the multiple low-power FPGA platforms for rapid scalability. This allows the FPGA boards to be used in large scale projects and support the high computational demand for the power-hungry applications.

- Description:
- Advancements in machine learning over the past several decades have provoked a sharp increase in humanity's ability to gather and analyze bulk data at a deep level of understanding - and use that data to make informed decisions and solve critical issues. Artificial Neural Networks (ANN's) have been used to handle analysis of various high-dimensional data types - including audio, video, visual, and numerical data. Medical Infrared Thermography (IT) utilizes infrared light to produce surface-temperature measurements of thermal images which may be used for medical diagnosis and analysis. Surface temperature thermograms give insight into the subsurface blood flow and tissue properties in a medically non-invasive and cost-effective manner. Image analysis of thermograms with ANN's have already been used to diagnose conditions and identify patterns in medical imagery for humans and many other species - but in particular - there are not many examples in the literature of its use in dogs (Canis lupus familiaris). Dogs have varying thermal surface temperature patterns based on breed/mix, coat type, relative size, and other characteristics. Our research seeks to identify a normal thermal pattern/range of dogs and determine how machine learning technologies may be applied to diagnose medical phenomena therein. We are developing a Convolutional Neural Network that seeks to analyze paired thermal/visual images of dogs alongside numerical data and determine if the dog has a normal or abnormal thermal pattern. Further classification, training, and network optimization may lead to increased diagnostic capability.

- Description:
- West Nile virus (WNV) is a neurotropic flavivirus capable of causing irreparable neuronal injury and encephalitis which can potentially result in lethal disease. In order to control WNV replication and any associated neurologic disease, it is vital that anti-viral T cells enter the central nervous system (CNS) and become fully activated. Dendritic cells (DCs) are powerful APCs responsible for activating T cells and regulating their effector immune responses, however, their role within the CNS during WNV encephalitis remains uncertain. Previously, we detected the presence of DEC-205-expressing DCs within the perivascular spaces of the CNS during WNV encephalitis. DEC-205 is an endocytic receptor expressed on a subset of DCs which have been shown to be effective at cross-presentation and initiating anti-viral immunity. We hypothesize that DEC-205 expressing DCs are critical in the immune defense against WNV encephalitis via the activation of anti-viral T cell immunity. In this study, the ability of DEC-205 expressing DCs to limit viral infection, replication, and neuronal injury will be examined utilizing a well-established mouse model of WNV encephalitis in DEC-205 expressing wild-type (WT) mice and DEC-205 gene knockout (KO) mice following WNV infection. In future studies, utilizing the same mouse model, the mechanisms by which DEC-205 expressing DCs are able to induce protection against WNV encephalitis will be determined by investigating the a

- Description:
- Fanfiction allows people from various communities to celebrate their favorite fandoms, characters, and relationships together. Over the past decade, fanfiction has developed into a center for activism through the racebending movement in online communities like Tumblr. The following research focuses on how racebending in fanfiction provides women of color with a space where they can have creative power and a voice for their unique narratives by recasting white female characters with women of color instead. There is primarily a focus on women of color due to how studies show women having lower self-esteem with increased media exposure as opposed to men, and how stereotyped representations of female minorities on screen have a profound effect on girls of color. The research shows why racebending is of importance for women of color by highlighting the lack of central characters played by them in movies and television, as well as the lack of these women in creatives roles such as writers and directors. The deficiency of women of color both onscreen and off screen directly leads to the homogenous nature of mainstream media and the occurrence of whitewashing, which is detrimental because as Dr. Lori Kido Lopez presents in "Fan-Activists and the Politics of Race in The Last Airbender" it supports the idea that whiteness can stand in for all racial difference. Fanfiction counters this idea through racebending, where women of color can see positive representations of themselves by being producers of their own media instead of simply consumers of it.

- Description:
- Butanol is a gasoline substitute and naturally derived, making the production of butanol of increasing importance. Butanol is produced through acetone, butanol, ethanol (ABE) fermentation pathway in some bacteria, including the Clostridium species. Because of the increasing interest in butanol production, understanding the metabolic flux through the ABE pathway is important for optimizing the recovery of the biofuel. Global profiling of the ABE pathway intermediates is difficult due to the volatile nature of the metabolites and their structural similarity. Our goal is to develop a procedure for the quantification of butanol and butyric acid using Nuclear Magnetic Resonance Spectroscopy (NMR). Due to the complexity of the spectra, traditional 1H-NMR is insufficient for quantification, so we developed 2D approaches for quantification that involve J-resolved spectroscopy (JRES) and Total Correlation Spectroscopy (TOCSY) through the application of a calibration curve. We created a calibration curve with standards and then tested the correlation of the expected concentration of an analyte with the known concentration, and found that they were in high agreement (R2 = 0.97). Overall, there were 4 successful reproducible trails. Although the 1H approach was the most accurate, we are working on improving the 2D approaches so that butanol and butyric acid can be quantified in a complex sample. Once these tests work on known sample, they can be moved onto real samples from Dr. Wei-Jen Lin's lab from Biological Sciences.

- Description:
- Human comfort in regards to clothing systems depends upon the ability of the fabrics and their construction to transmit perspiration away from the body. If the clothing system is inefficient in this regard, the wearer will experience a great deal of discomfort and physiological distress. It is critical, therefore, for the clothing to be "breathable" This project was an attempt to quantify the effect of environmental factors on the creation and transport of moisture/moisture vapor through different fabrics. The physics of the phenomenon will be described. The design and construction of a custom-made apparatus will be reported. The apparatus utilizes a controlled water heater, a humidity/temperature sensor, a fan, and a weighing scale. The results will be reported and discussed.

- Description:
- Traffic congestion on the freeways is one of the worst issues in California. During peak hours, traffic can slow down to a stop-and-go crawl. A significant cause of this behavior is driving habits: human beings have a tendency to drive closer as they slow down, which makes merging difficult and exacerbates the slowness. The Tail Gator app uses machine vision to, when placed on the dashboard of a normal car, collect and relay information to the driver in a hands-free manner regarding the vehicle in front of them. It would tell the driver the distance and relative speed of the car in front of them, which the driver can then use to build good, anti-congestion driving habits and stop tailgating in traffic. The technology behind this has further applications: it could be used to recommend to drivers optimal speed and acceleration based on the traffic situation, which would also be useful in guiding the behaviors of self driving cars to better the road for everyone.
