Connected Vehicles At Signalized Intersections: Traffic Signal Timing Estimation And Optimization, S. Alireza Fayazi

All Dissertations

Summary: While traffic signals ensure safety of conflicting movements at intersections, they also cause much delay, wasted fuel, and tailpipe emissions. Frequent stops and goes induced by a series of traffic lights often frustrates passengers. However, the connectivity provided by connected vehicles applications can improve this situation. A uni-directional traffic signal to vehicle communication can be used to guide the connected vehicles to arrive at green which increases their energy efficiency; and in the first part of the dissertation, we propose a traffic signal phase and timing estimator as a complementary solution in situations where timing information is not available …

Experimental Characterization And Simulation Of Carbon Nanotube Strain Sensing Films, Nagendra Krishna Chaitanya Tummalapalli

Masters Theses

Carbon Nanotubes (CNTs) have excellent mechanical, electrical and electromechanical properties. These properties led to a lot of novel applications. Due to change in electrical properties under mechanical loading, these composites have potential applications in strain sensors, when these are fabricated as films. CNT-based films are commonly fabricated using different physical and chemical techniques based on the property requirements governing those applications. In this work, CNT films were prepared using wet chemical based methods and chemical vapor deposition techniques.

Plasma chemical vapor deposition using microwave power is used in the first method to deposit films on silicon substrates, using Nickel film …

The Impact Of A Student Device Technology Integration Professional Development Program On K-6 Performance Data, Peter Grostic

Masters Theses

When schools choose to secure devices for their students to integrate into class, they are engaging in a student device technology integration initiative. Results of such initiatives so far have been inconsistent (Bebell & Kay, 2010, Gulek & Demirtas, 2005). These inconsistencies may be, in part, due to poor professional development and/or incomplete data collection. The purpose of this study is to examine the impact of a professional development program for teachers on the effectiveness of a student device technology integration initiative. “Effectiveness” will be defined by standardized test data as well as student attendance data and student behavior referral …

Analytical Modeling And Numerical Simulation Of A Thermoelectric Generator Including Contact Resistances, Shripad Dhoopagunta

Masters Theses

With increasing demand for energy harvesting systems, research has been conducted in different areas in which Thermoelectric Generators (TEG) find their way into the top of many available resources. Out of many energy harvesting systems available, TEGs are comparatively easier to study, to manufacture and also to comprehend while producing enough energy for applications they find use in. They are solid state devices, meaning; they do not have any moving parts and hence makes them durable. Most of the energy that goes out of the automobile as exhaust is reused to power the TEGs. In most of the works that’s …

This report is focused on the hardware modifications and the firmware used in order to drive the golf cart from a computer.

Electronic Deer Warning System, David Zhuo, Anlang Lu

Computer Engineering

Deer-vehicle collisions (DVCs) are extremely dangerous, often injuring or even killing drivers. Unfortunately, this form of automotive accident is commonplace in the United States. According to the NHTSA, DVCs result in 200 human deaths a year.2

Despite these deadly incidents, there currently are no deployed federal or state systems for preventing DVCs. There are many consumer electronic deer deterrent products, but their long-term effectiveness is questionable.3 In fact, there does not appear to be much research into electronic deer deterrent systems. Aside from constant audio output and electric shock, no other means of electronic deterrent exist. Even if fixed deterrents …

Power Distribution:Protection Analysis, Avneet S. Samra

Electrical Engineering

The objective of this project is to build a radial distribution system that operates on a lower voltage. The system consists of a transmission line protected by a SEL-351 Relay, a three- phase transformer protected by a SEL-587 Relay, and a three-phase induction motor protected by a Cooper Form 6 Controller. The SEL-351, SEL-587, and the Cooper Form 6 Controller are microprocessor-based relays that are used to provide protection under faulted conditions. When a fault is detected in the system, the closest upstream relay sends a trip signal to its assigned local breaker. The SEL-351 provides overcurrent protection for the …

Active Contact Lens - Low Power Backscattering Sensor-To-Antenna Integration Circuitry, Caleb B. Porter

Electrical Engineering

The Active Contact Lens measures the cornea-scleral radius of the wearer’s eye, which correlates to intraocular pressure (IOP), Glaucoma’s primary indicator. IOP varies throughout the day, and is drastically different from person to person, so constantly measuring it over a period of a few days can provide individualized tracking of the disease’s development and will help doctors develop personalized treatment schedules to treat the disease more precisely.

The Active Contact Lens sensor measures strain, based on the cornea-scleral radius, and reports the results wirelessly, to allow monitoring of an individual’s IOP over time. The lens is powered similarly to a …

Designing A Power Distribution System For The Arce 257 Revit Structural Model, Reid Wilhelm

Electrical Engineering

The construction industry needs engineers. Mechanical, electrical, and plumbing engineers, better known as MEPs, comprise a large number of employees who design and assist in the building of commercial structures. In particular, electrical engineers design power distribution systems for these buildings, including the power, lighting, low voltage, and fire protection subsystems.

Here at Cal Poly, architectural engineers enrolled in ARCE 257 create authentic structural plans for a fictitious two-story structure. This senior project transforms these structural plans into an architectural model and creates a power distribution system for the entire building. This is done through a building information modeling (BIM) …

Experimental Evaluation Of Structural Steel Coating Systems, Elias Anis Toubia, Sadra Emami

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

Departments of transportation (DOTs) currently use the conventional three-coat system as the predominant choice for the corrosion protection of steel bridge structures. Eliminating one step in the coating process could potentially save time and cost associated with lane closures and traffic control costs. This research paper evaluates several two-coat systems based on the zinc-rich primer and polysiloxane topcoat technology. All samples were conditioned and coated in a state-of-the-art, climate-controlled paint booth, simulating common field ENvironmental CONditions (ENCON) (ENCON 1: 25 °C/50% RH, ENCON 2: 10 °C/40%RH, and ENCON 3: 32°C/80% RH). Accelerated weathering tests were performed on 435 coated samples …

Integration Over Curves And Surfaces Defined By The Closest Point Mapping, Catherine Kublik, Richard Tsai

Mathematics Faculty Publications

We propose a new formulation for integrating over smooth curves and surfaces that are described by their closest point mappings. Our method is designed for curves and surfaces that are not defined by any explicit parameterization and is intended to be used in combination with level set techniques. However, contrary to the common practice with level set methods, the volume integrals derived from our formulation coincide exactly with the surface or line integrals that one wishes to compute. We study various aspects of this formulation and provide a geometric interpretation of this formulation in terms of the singular values of …

The Risk Of Memory, The Cost Of Forgetting, M. Shawn Copeland

Journal of the Black Catholic Theological Symposium

This article, a revision of the Raymund Schwager, S.J., Memorial Lecture, given at the Colloquium on Religion and Violence, July 10, 2015, St. Louis University, focuses on the risk of memory and the cost of forgetting. Memory, and the act of remembering both individually and collectively as a society, involves risk to a society’s present, past, and future. Forgetting comes at a price exacted by the past, but paid in the present for the future, even as nations sometimes choose to forget. This thesis is developed in three parts – common meaning and memory as grounding a community; the cost …

Review: 'The White House Vice Presidency: The Path To Significance, Mondale To Biden', Christopher J. Devine

Political Science Faculty Publications

In his book, Joel K. Goldstein has made an ambitious attempt to explain “the most impressive development in American political institutions during the past four decades” (p. 301): the creation of the “White House vice presidency.” The essential features of this newly invigorated institution—historically hobbled by its limited constitutional role and divided institutional identity—entail serving as a senior adviser to, and troubleshooter for, the president, with the support of necessary resources. Key among those resources are regular access to the president and his staff, access to intelligence briefings and Oval Office paper flow, and the integration of vice presidential staff …

Doppler Temperature Coefficient Calculations Using Adjoint-Weighted Tallies And Continuous-Energy Cross Sections In Mcnp6, Matthew A. Gonzales

Nuclear Engineering ETDs

The calculation of the thermal neutron Doppler temperature reactivity feedback co- efficient, a key parameter in the design and safe operation of advanced reactors, using first order perturbation theory in continuous energy Monte Carlo codes is challenging as the continuous energy adjoint flux is not readily available. Traditional approaches of obtaining the adjoint flux attempt to invert the random walk process as well as require data corresponding to all temperatures and their respective tem- perature derivatives within the system in order to accurately calculate the Doppler temperature feedback.

A new method has been developed using adjoint-weighted tallies and On-The-Fly (OTF) …

Optimal Sensing And Transmission In Energy Harvesting Sensor Networks, Xianwen Wu

Graduate Theses and Dissertations

Sensor networks equipped with energy harvesting (EH) devices have attracted great attentions recently. Compared with conventional sensor networks powered by batteries, the energy harvesting abilities of the sensor nodes make sustainable and environment-friendly sensor networks possible. However, the random, scarce and non-uniform energy supply features also necessitate a completely different approach to energy management.

A typical EH wireless sensor node consists of an EH module that converts ambient energy to electrical energy, which is stored in a rechargeable battery, and will be used to power the sensing and transmission operations of the sensor. Therefore, both sensing and transmission are subject …

A Phenomenological Study Of Practicing Educators’ Personal And Collaborative Experiences Within A Climate Of High Stakes Individual Accountability, Kathy L. Stewart

Dissertations

With the national focus in education turning to increasing student achievement and closing achievement gaps between demographic groups, federal and state policy has extended responsibility and high stakes accountability for student growth and achievement. Overall, student achievement status and elimination of achievement gaps between demographically defined sub-groups of students remain cornerstones of accountability under ESEA and now ESSA. Under the Obama Administration, however, accountability for academic growth was extended to individual classroom teachers and school and district-level administrators through federal policy provisions tying student growth to performance evaluation. As a result, many states, including Michigan, enacted legislation to mandate high …

Three Essays On Financial Constraints And Foreign Direct Investment, Todd Sarnstrom Ii

Dissertations

This three–essay dissertation makes contributions to the literature on foreign direct investment (FDI) and its relationship with collateral and the exchange rate. FDI refers to an investment made by a firm to establish or acquire a long–lasting interest in another firm operating outside its home country. Often, FDI involves substantial fixed costs that require the investing firm to seek external financing. Collateral has been identified as an important factor in the external financing of FDI. Firms lacking collateral are constrained in their ability obtain external financing. Exchange rates have also been identified as a factor in FDI. Exchange rate movements …

The Impact Of Procedural Compliance To The Individualized Education Program Document On Student Achievement And Academic Benchmarks, Christine Robertson

Dissertations

Currently, the practice of special education service delivery is undergoing a transformation. This transformation is largely due to the United State Department of Education Office of Special Education’s current framework of “results driven accountability” for the determination of program effectiveness (USDOE, 2011). Since the inception of the Individuals with Disabilities Education Act (IDEA) more than 40 years ago, students with disabilities have been provided increasing access to general educational programs and curriculum. Academic outcomes for those same students, however, have not improved, and the achievement gap between students with and without disabilities continues to widen when measured on national and …
