Evaluation Of Variable Speed Limits Using A Genetic Algorithm Approach To Calibrate A Vissim Model, Brian Joseph Schaefer

Masters Theses

"The variable speed limit (VSL) system has been adopted on more and more roadways across the globe as an engineering tool for controlling traffic flow, particularly during congestion situations. An important and fundamental question raised among traffic engineers is: Are the costs of installing and operating variable speed limits really justified? In order to answer this question, this thesis measures the effectiveness of the VSL system applying the VISSIM microscopic simulation model to a non-recurrent congestion situation. For the analysis, a section of interstate was modeled in VISSIM and calibrated so that the simulated results closely reproduce the observed data …

Target Detection And Feature Evaluation Of Airborne Mine Target Images, Deepika Kamakshi Timmavajjula

Masters Theses

"Target segmentation and detection problem is one of the preliminary approaches in analyzing an image. Many edge, region and texture based techniques have been proposed in literature. These techniques often have limitations based on types of image data, kind of segmentation of interest and the problem domain. Mine detection problem dealt with for this thesis has mine target images which have a center target consisting of false alarm or mine patch which has to be detected and features evaluated to evaluate various parameter performances. Thus, segmenting the mine patch becomes the first step of analyzing these images. This thesis is …

Design And Critical Performance Evaluation Of Horizontal Axis Hydrokinetic Turbines, Suchi Subhra Mukherji

Masters Theses

"The current work discusses the hydrodynamic performance of horizontal axis hydrokinetic turbines (HAHkT) under different turbine geometries and flow conditions. Hydrokinetic turbines are a class of zero-head hydropower systems which utilize kinetic energy of flowing water to drive a generator. However, such turbines often suffer from low-efficiency. A detailed computational fluid dynamics study was performed using a low-order k-[omega] SST (Shear Stress Transport) turbulence model to examine the effect of each of tip-speed ratio, solidity, angle of attack and number of blades on the performance of small HAHkTs with a power capacity of 10 kW. The numerical models (both two-dimensional …

The determination of detention basin effectiveness was based upon these parameters. The NRCS distribution method is widely used; however, many who use it …

Etherannotate: A Transparent Malware Analysis Tool For Integrating Dynamic And Static Examination, Joshua Michael Eads

Masters Theses

"Software security researchers commonly reverse engineer and analyze current malicious software (malware) to determine what the latest techniques malicious attackers are utilizing and how to protect computer systems from attack. The most common analysis methods involve examining how the program behaves during execution and interpreting its machine-level instructions. However, modern malicious applications use advanced anti-debugger, anti-virtualization, and code packing techniques to obfuscate the malware's true activities and divert security analysts. Malware analysts currently do not have a simple method for tracing malicious code activity at the instruction-level in a highly undetectable environment. There also lacks a simple method for combining …

Minimize End-To-End Delay Through Cross-Layer Optimization In Multi-Hop Wireless Sensor Networks, Yibo Xu

Masters Theses

"End-to-end delay plays a very important role in wireless sensor networks. It refers to the total time taken for a single packet to be transmitted across a network from source to destination. There are many factors could affect the end-to-end delay, among them the routing path and the interference level along the path are the two basic elements that could have significant influence on the result of the end-to-end delay. This thesis presents a transmission scheduling scheme that minimizes the end-to-end delay when the node topology is given. The transmission scheduling scheme is designed based on integer linear programming and …

Computational Intelligence Methods In Wireless Sensor Networks, Raghavendra V. Kulkarni

Doctoral Dissertations

"Wireless sensor networks (WSNs) are networks of autonomous nodes that sense, compute and communicate in order to monitor an environment collectively. Ad hoc deployment, dynamic environment and resource constraints in nodes need to be considered while addressing WSN challenges such as deployment, localization, routing and scheduling. Adaptive mechanisms that exhibit intelligent behavior in complex and dynamic environments are desirable to address these challenges. The potential of computational intelligence ( CI) based approaches for addressing WSN challenges is investigated in this study. Contributions of this dissertation are in the following three areas: critical literature analysis, new architectures and approaches, and new …

Prediction Of Soft Error Response Of Integrated Circuits To Electrostatic Discharge Injection Via Simulation Field; Package Interaction For Electrostatic Discharge Soft Error Prediction; Full Wave Model For Simulating Noise Ken Electrostatic Discharge Generator, Argha Nandy

Masters Theses

"In the first section, a concept for analyzing soft error response in ICs to ESD via coupling through flex cable structures is presented. Its novelty lies in accounting for the transient electromagnetic fields radiated by the ESD generator that couples to the flex cable PCB thereby causing disturbance on the IC under test. This is accomplished in three stages; first by developing a full wave model of the DUT which includes modeling the PCB and flex cable geometry and validating it in frequency domain with regard to the transfer impedance. This followed by combining the ESD generator with the DUT …

Near Impossible To Enforce At Best, Unconstitutional At Worst: The Consequences Of Maryland’S Text Messaging Ban On Drivers, Alan Lazerow

Richmond Journal of Law & Technology

A local newspaper reports that your state recently passed a law prohibiting citizens from “writ[ing] or send[ing] a text message while operating a motor vehicle.” Armed with the knowledge of the texting ban, you, being a reasonable citizen, are likely to proceed in one of at least three ways, each of which exposes the statute’s fundamental flaws.

Analysis Of Models For Longitudinal And Clustered Binary Data, Weiming Yang

Mathematics & Statistics Theses & Dissertations

This dissertation deals with modeling and statistical analysis of longitudinal and clustered binary data. Such data consists of observations on a dichotomous response variable generated from multiple time or cluster points, that exhibit either decaying correlation or equi-correlated dependence. The current literature addresses modeling the dependence using an appropriate correlation structure, but ignores the feasible bounds on the correlation parameter imposed by the marginal means.

The first part of this dissertation deals with two multivariate probability models, the first order Markov chain model and the multivariate probit model, that adhere to the feasible bounds on the correlation. For both the …

Liberty And The Normative Force Of The Law In Montesquieu's The Spirit Of The Laws, Cory Wimberly

Philosophy Faculty Publications

The aim of this essay is explore what demands living in liberty places on citizens in Montesquieu’s The Spirit of the Laws. In contrast to the ideas of liberty from many of the thinkers that were to follow him, Montesquieu’s notion of liberty requires that citizens subject themselves to the regulative relationships required by his normative conception of the law. For Montesquieu, living in liberty is not just a situation in which one avoids what the law forbids and is otherwise left ’free’ without interference and coercion. For Montesquieu, liberty is a positively elaborated ideal with normative demands and a …

A Sustainable Campus? Students’ Perspectives Of Informal Learning About Sustainability, Debby Cotton, Alan Dyer, Jennie Winter

School of Law, Humanities and Social Sciences

Sustainability is an important issue in Higher Education and is increasingly embedded within the formal curriculum alongside the greening of university campuses and estates. The University of Plymouth has a strong reputation for sustainability, currently holding the top position in the People and Planet Green League. The university aims to embed sustainability throughout the university curriculum, community, culture and campus (University of Plymouth 2006). However, to date there has been little research which explores the student perspective of campus sustainability. Understanding the student perspective is necessary if educators are to establish if and how campus-based learning about sustainability takes place. …

Livelihoods And Family Formation Among Eritrean Refugees In Cairo, Erin A. Ajygin

Theses and Dissertations

This thesis uses data gathered from a survey conducted in November and December of 2009 to provide an overview of the demographic profile and livelihoods strategies of a sample of Eritrean refugees in Cairo. Study results revealed that the Eritreans surveyed were predominantly single, childless and living in Cairo without family. While much of the existing literature on refugee livelihoods has focused on refugees living in camp settings and/or on refugees’ roles as spouses and parents, this study examined the strategies engaged by a group of single, urban refugees. Using a livelihoods framework comprised of capabilities, assets and activities, survey …

Xenophobia: The Consequences Of Being A Zimbabwean In South Africa, Philip Edward Culbertson

Theses and Dissertations

This paper seeks to explain and describe the xenophobia and xenophobic attacks of Zimbabwean refugees and migrants in South Africa. The political and social instability in Zimbabwe has led to mass exodus of Zimbabweans in search of stability and a means to survive. Many of these Zimbabweans have sought opportunity and refuge in South Africa only to be met with hurdles that metastasized into xenophobia. Research was done on the target population of Zimbabweans in Central Methodist Church in Johannesburg, along with interviews conducted through Medicines Sans Frontiers, and active players in the civil society in Cape Town.

Land Use And Water Supply, Susan Kelly, Joanne Hilton

Water Matters!

As New Mexico grows and develops, there is a continuing increase in water demand and the need to provide additional supplies. Recent studies estimate the current population of the State to be about two million people, and the population is expected to grow to approximately 3,400,000 by 2050. Regional water plans project water demands for 16 regions within New Mexico. The total projected new water use associated with population growth—the public water supply and associated commercial sectors, exclusive of agriculture, mining, or other industries—ranges from 280,000 to 380,000 acre-feet per year of new water supply needed in the next 40 …
