Fpga-Based Implementation Of Dual-Frequency Pattern Scheme For 3-D Shape Measurement, Brent Bondehagen

Theses and Dissertations--Electrical and Computer Engineering

Structured Light Illumination (SLI) is the process where spatially varied patterns are projected onto a 3-D surface and based on the distortion by the surface topology, phase information can be calculated and a 3D model constructed. Phase Measuring Profilometry (PMP) is a particular type of SLI that requires three or more patterns temporarily multiplexed. High speed PMP attempts to scan moving objects whose motion is small so as to have little impact on the 3-D model. Given that practically all machine vision cameras and high speed cameras employ a Field Programmable Gate Array (FPGA) interface directly to the image sensors, …

A Comprehensive Hdl Model Of A Line Associative Register Based Architecture, Matthew A. Sparks

Theses and Dissertations--Electrical and Computer Engineering

Modern processor architectures suffer from an ever increasing gap between processor and memory performance. The current memory-register model attempts to hide this gap by a system of cache memory. Line Associative Registers(LARs) are proposed as a new system to avoid the memory gap by pre-fetching and associative updating of both instructions and data. This thesis presents a fully LAR-based architecture, targeting a previously developed instruction set architecture. This architecture features an execution pipeline supporting SWAR operations, and a memory system supporting the associative behavior of LARs and lazy writeback to memory.

Power-Efficient And Low-Latency Memory Access For Cmp Systems With Heterogeneous Scratchpad On-Chip Memory, Zhi Chen

Theses and Dissertations--Electrical and Computer Engineering

The gradually widening speed disparity of between CPU and memory has become an overwhelming bottleneck for the development of Chip Multiprocessor (CMP) systems. In addition, increasing penalties caused by frequent on-chip memory accesses have raised critical challenges in delivering high memory access performance with tight power and latency budgets. To overcome the daunting memory wall and energy wall issues, this thesis focuses on proposing a new heterogeneous scratchpad memory architecture which is configured from SRAM, MRAM, and Z-RAM. Based on this architecture, we propose two algorithms, a dynamic programming and a genetic algorithm, to perform data allocation to different memory …

An Attitude Determination System With Mems Gyroscope Drift Compensation For Small Satellites, Maxwell Bezold

Theses and Dissertations--Electrical and Computer Engineering

This thesis presents the design of an attitude determination system for small satellites that automatically corrects for attitude drift. Existing attitude determination systems suffer from attitude drift due to the integration of noisy rate gyro sensors used to measure the change in attitude. This attitude drift leads to a gradual loss in attitude knowledge, as error between the estimated attitude and the actual attitude increases.

In this thesis a Kalman filter is used to complete sensor fusion which combines sensor observations with a projected attitude based on the dynamics of the satellite. The system proposed in this thesis also utilizes …

Visual Attitude Propagation For Small Satellites, Samir Ahmed Rawashdeh

Theses and Dissertations--Electrical and Computer Engineering

As electronics become smaller and more capable, it has become possible to conduct meaningful and sophisticated satellite missions in a small form factor. However, the capability of small satellites and the range of possible applications are limited by the capabilities of several technologies, including attitude determination and control systems. This dissertation evaluates the use of image-based visual attitude propagation as a compliment or alternative to other attitude determination technologies that are suitable for miniature satellites. The concept lies in using miniature cameras to track image features across frames and extracting the underlying rotation.

The problem of visual attitude propagation as …

Power System State Estimation Using Phasor Measurement Units, Jiaxiong Chen

Theses and Dissertations--Electrical and Computer Engineering

State estimation is widely used as a tool to evaluate the real time power system prevailing conditions. State estimation algorithms could suffer divergence under stressed system conditions. This dissertation first investigates impacts of variations of load levels and topology errors on the convergence property of the commonly used weighted least square (WLS) state estimator. The influence of topology errors on the condition number of the gain matrix in the state estimator is also analyzed. The minimum singular value of gain matrix is proposed to measure the distance between the operating point and state estimation divergence.

To study the impact of …

Power Control Of Single-Stage Pv Inverter For Distribution System Volt-Var Optimization, Xiao Liu

Theses and Dissertations--Electrical and Computer Engineering

The output power variability of intermittent renewable sources can cause significant fluctuations in distribution system voltages. A local linear controller that exploits the capability of a photovoltaic inverter to provide both real and reactive power is described. This controller substitutes reactive power for real power when fluctuations in the output of the photovoltaic source are experienced. In this way, the inverter can help mitigate distribution system voltage fluctuations. In order to provide real and reactive to the grid, a three-phase grid-connected single-stage photovoltaic system with maximum power point tracking and power control is described. A method of reducing the current …

GIC is treated at a micro level considering its effects on the power system assets like Transformers and also at a macro level with respect to issues like Voltage instability. In illustration, several simulations are made on a transformer & the …

The Point Of A Points System: Attracting Highly Skilled Immigrants The United States Needs And Ensuring Their Success, Carla Tabag

Vanderbilt Journal of Transnational Law

In a globalizing world, labor is an increasingly mobile and competitive resource. Responding to this changing labor market, countries like Canada, the United Kingdom, and Australia have adopted points systems with the goal of attracting talented, highly skilled immigrants. In the United States, however, much of the national focus on immigration remains on deterring illegal immigration rather than attracting immigrants that the United States needs to remain competitive in a globalized world. But attracting skilled immigrants is only one ingredient to a successful points system; a country must also ensure those immigrants are successful and use their talents to the …

Plain Packaging And The Interpretation Of The Trips Agreement, Susy Frankel, Daniel Gervais

Vanderbilt Journal of Transnational Law

Plain packaging of cigarettes as a way of reducing tobacco consumption and its related health costs and effects raises a number of international trade law issues. The plain packaging measures adopted in Australia impose strict format requirements on word trademarks (such as Marlboro or Camel) and ban the use of figurative marks (colors, logos, etc.). As a result, questions have been raised as to plain packaging's compatibility with the World Trade Organization's (WTO) Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement).

WTO members can validly take measures to protect and promote public health, but in doing so they …

A Three-Dimensional Flow Model For Different Cross-Section High-Velocity Channels, Abdulla Abo

Other Faculty of Science and Engineering Theses

ABSTRACT High velocity channels are typically designed to discharge surplus water during severe flood events, and these types of flow are distinguished by high velocity, usually supercritical. A major challenge in high velocity channel design is to predict the free surface flow. Being able to predict the free surface flow profile beforehand can assist in selecting the best design for the channel as a whole. When the flow encounters a bridge pier, the streamline of the flow is separated and pressure may drop to a minimum; in contrast, velocity rises to its maximum value. As a result, cavitation damage may …

Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Studies of speech sensorimotor learning often manipulate auditory feedback by modifying isolated acoustic parameters such as formant frequency or fundamental frequency using near real-time resynthesis of a participant's speech. An alternative approach is to engage a participant in a total remapping of the sensorimotor working space using a virtual vocal tract. To support this approach for studying speech sensorimotor learning we have developed a system to control an articulatory synthesizer using electromagnetic articulography data. Articulator movement data from the NDI Wave System are streamed to a Maeda articulatory synthesizer. The resulting synthesized speech provides auditory feedback to the participant. This …

Personality's Influence On Burnout: An Unfinished Puzzle, David Andrew Periard

Browse all Theses and Dissertations

This study examines the relationship between emotional exhaustion-the main component of burnout-and several facets of the Big Five Factors of personality. Previous research has found small relationships between the Big Five Factors and emotional exhaustion. I hypothesized that the facets of trust, cooperation, orderliness, and self-discipline will have curvilinear relationships with emotional exhaustion. The facets of vulnerability and depression were also hypothesized to moderate the curvilinear relationships between orderliness and self-discipline and emotional exhaustion. Regression analyses only found a curvilinear relationship between order and personal burnout when vulnerability was controlled for. A significant quadratic-by-linear interaction was found between order and …

Assessing The Effects Of Multi-Modal Communications On Mental Workload During The Supervision Of Multiple Unmanned Aerial Vehicles, Sharon Claxton Bommer

Browse all Theses and Dissertations

Human supervisory control (HSC) systems that require intermittent human input of commands to create actions within the system are helpful in reducing the human's mental workload (MWL). HSC systems are commonly employed in the piloting and control of unmanned aerial vehicles (UAVs). As the ratio of UAVs to operators increases there is a clear need to understand the effort required to complete task requirements. Specifically, this research explored MWL relative to multi-modal communications using subjective and physiological measures. To accomplish this, a cognitive model was developed to understand the relationship between tasks and MWL. MWL was manipulated by measuring three …

The Little Brother Syndrome And Nuclear Proliferation, An Exploratory Analysis Of Pakistan And North Korea's Risk Prone Policies, Richard Ellis Hebblethwaite

Browse all Theses and Dissertations

The successful pursuit of nuclear weapons technology by Pakistani and North Korean leaders has fundamentally shifted the post war nuclear paradigm that established the monopoly of five nuclear powers over nuclear weapons and supplies of fissile materials under the Non-proliferation Treaty (NPT). How does one explain the daring nuclear pursuit of Pakistan and North Korea and their success in achieving this capability? Numerous theories have tried to explain both the rationale and the causal factor(s) for nuclear proliferation and specifically nuclear arms. While realism and neo-realism concentrate on the fear of the unknown; i.e., the international system and military power …

Application Of The Augmented Operator Function Model For Developing Performance Metrics In Persistent Surveillance, Tiffany M. Paul

Browse all Theses and Dissertations

Difficulties with the implementation of persistent Wide Area Motion Imagery (WAMI) sensors to support real-time military missions have risen within Intelligence, Surveillance, and Reconnaissance organizations. In this study, cognitive models were developed of operators performing real-time missions currently supported by narrow field of view Full Motion Video (FMV) and WAMI sensors. These models were used in conjunction with a cognitive task analysis, creating an augmented operator function model (OFM-COG). This thesis describes the OFM-COG and demonstrates how this model-based analysis technique can document the cognitive implications of persistent surveillance with motion imagery. The analytic procedures required to build this model …
