On The Effects Of Small-Scale Fading And Mobility In Mobile Wireless Communication Network, Bandana Paudel

Masters Theses

"In this study, a comprehensive analysis of the impact of mobility on end-to-end performance measures of Mobile Ad Hoc Network is performed by using small-scale fading models. Network simulation is performed in order to study a wide range of phenomena occurring during MANET communication. The effectiveness of three reactive routing protocols against different level of mobility is observed under varying network parameter like the network size, number of nodes and network connectivity. The study reveals that the network sparseness or density favors one or the other routing mechanism under varying mobility. Outcome of the simulation also provides a great deal …

Localization Of Nodes In Wired And Wireless Networks, Hindu Kothapalli

Masters Theses

"This thesis focuses on the implementation of algorithms for localization of nodes in wired and wireless networks. The thesis is organized into two papers. The first paper presents the localization algorithms based on time of arrival (TOA) and time difference of arrival (TDOA) techniques for computer networks such as the Internet by using round-trip-time (RTT) measurements obtained from known positions of the gateway nodes. The RTT values provide an approximate measure of distance between the gateway nodes and an unknown node. The least squares technique is then used to obtain an estimated position of the unknown node. The second paper …

Stressed-Eye Analysis And Jitter Separation For High-Speed Serial Links, Nitin Radhakrishnan

Masters Theses

"As the computer and electronics industry moves towards higher data rates, the most important concern in the field of signal integrity is jitter. A data communication link path often consists of a transmitter, a channel, and a receiver. Many mechanisms can contribute to jitter, a timing uncertainty in the received signal. For example, transmitters have intrinsic noise sources that contribute to random jitter and to certain types of deterministic jitter. In addition, external coupling may cause periodic jitter. The bandwidth limitation of the channel also contributes to a fourth type of jitter, inter-symbol interference. This thesis studies the various components …

Fault Detection And Prediction With Application To Rotating Machinery, Gary R. Halligan

Masters Theses

"In this thesis, the detection and prediction of faults in rotating machinery is undertaken and presented in two papers. In the first paper, Principal Component Analysis (PCA), a well known data-driven dimension reduction technique, is applied to data for normal operation and four fault conditions from a one-half horsepower centrifugal water pump. Fault isolation in this scheme is done by observing the location of the data points in the Principal Component domain, and the time to failure (TTF) is calculated by applying statistical regression on the resulting PC scores. The application of the proposed scheme demonstrated that PCA was able …

Feasibility Of A Human Performance Model In Consequence Management, Kashmeera Ghosh

Masters Theses

"Human civilization has always encountered unpredictable disasters as a result of natural events. Now it also faces the disasters caused by terrorist attacks. Governments must have consequence management plans in place to protect public health and safety, restore essential services, and provide emergency relief to affected businesses and individuals. Human performance models predict outcomes in complex dynamic situations. Such models can simulate disaster management procedures under varying circumstances. This work applies human performance modeling in a terrorist situation and evaluates possible uses of such models by first responders in practical consequence management applications. It includes a case study of an …

Real-Time Reconfiguration Of Programmable Logic Controller Communication Paths, Curtis Alan Parrott

Masters Theses

"This thesis explores the topics related to reconfiguration of Programmable Logic Controller's (PLC's) communications paths as it relates to network security and reliability. These paths are normally fixed, which creates a single fault point which can easily be disrupted by network failure or network based attack. With the ability for autonomous communications path reconfiguration these disruptions in communications can be avoided or bypassed. This work builds on these principles and a series of PLC programs are developed to facilitate several things: Scanning of the three different network types most common in PLC to PLC communications; a comprehensive network scan routine …

Filtering, Modeling, And Control Of Axial Force Signals In Friction Stir Welding Processes, Thomas Michael Oakes

Masters Theses

"In Friction Stir Welding Processes, good contact between tool and work piece can be accomplished through control of the axial force signals. A method of stochastic modeling is introduced and used in conjunction with a Kalman filter to develop empirical static and dynamic models relating the axial force to input process parameters. The filtering method reduces signal variance by an order of magnitude. The models are experimentally validated and used to design and implement a general tracking controller with disturbance rejection for axial force control. Online control of the axial force is experimentally validated for bead-on-plate welds using a 6061 …

Installing a submersible pump in a groundwater well can provide a source of water that is free of contamination and yields sufficient water throughout the year. Submersible pumps are typically powered from grid-power; however, an alternative energy source may be considered. An evaluation of the renewable energy resources has been conducted in Sacala las Lomas de San Martin Jilotepeque, Chimaltenango, Guatemala (Sacala). The drilling of a deep groundwater well has been proposed in Sacala to supply the community with sufficient, …

Comparison Of Dashboard-Based And Balanced Scorecard-Based Corporate Performance Management System, Lin Zhu

Masters Theses

"Under current hypercompetitive and technology driven economic environment, more companies are using a corporate performance management (CPM) system to gain more accurate understandings of the company goals and strategies and to craft methods of achieving those goals and strategies. While CPM systems are generally implemented in two approaches: dashboard approach and scorecard approach, very few studies examine the effectiveness of each type of CPM systems implementation. Therefore, the main objective of this study is to assess the effectiveness of a dashboard based and a balanced scorecard based corporate performance management system. The effectiveness is examined through management effectiveness, degree of …

Supporting Family Strength: The Use Of Transformative Mediation In A Pins Mediation Clinic, Robert A. Baruch Bush, Lisa Hershman, Robert Thaler, Christena Vitkovich

Hofstra Law Faculty Scholarship

This article describes, and explains the rationales for, the establishment of an innovative program in which a law school and two social services agencies are collaborating in a mediation clinic that uses the transformative model of mediation to serve clients in cases that seem ideally suited to benefit from this approach to practice—so-called “PINS” (persons in need of supervision) cases involving conflict within families, between parents and their adolescent children. The article first describes the evolution of the PINS system and the changing views of its purpose, especially in New York State. It then offers a brief introduction to the …

Whatever Happened To The Search For Truth, Monroe H. Freedman

Hofstra Law Faculty Scholarship

In a recent case,Gutman v. Klein, the court ordered the defendant to turn over his laptop so that it could be copied by the plaintiff’s lawyer and an expert. When the lawyer and the expert arrived at the appointed time, there was a two-hour delay. When they finally got the laptop, they found that it was hot to the touch and was missing a screw from the hard-drive plate, which made them suspicious.

As a result, the court ordered its own expert to examine the laptop.The court’s expert found that numerous files had been deleted and were unrecoverable, …

Sampling Edge Covers, William August Rummler

Theses

The random generation or sampling of combinatorial objects has important applications to statistical analyses in various domains, including physics and evolutionary biology. Some objects whose sampling has been well-studied are contingency tables, matchings, and independent sets. Edge covers are related to matchings in graph theory; however, their association does not appear to be of the sort where results for sampling matchings imply results for sampling edge covers. Consequently, we investigate the sampling of edge covers and prove that efficiently sampling so-called (1,2)-edge covers is possible under reasonable restrictions.

Towards Virtual Machine Integrity Using Introspection, Sammy Lin

Theses

The Integrity Measurements Architecture (IMA) provides attestation and integrity for Linux hosts. But what if an administrator wants to provide IMA functionality to an older (non-IMA capable) or a non Linux-based OS? If the system is deployed on top of a hypervisor, IMA functionality can be provided at the hypervisor level. This paper applies Virtual Machine Introspection (VMI) to provide IMA functionality to virtualized guest OSes. We implement a proof of concept library (using a shallow shadow filesystem) and integrate it with the Kernel-based Virtual Machine (KVM) hypervisor. The modifications provide the Linux host OS the ability to see when …

Data Center Design & Enterprise Networking, Christian Mahood

Theses

Today’s enterprise networks and data centers have become very complex and have completely integrated themselves into every facet of their represented organization. Organizations require Internet facing services and applications to be available at any part of the day or night. These organizations have realized that with centralized computing and highly available components, their technological presence with customers can be greatly enhanced. The creation of an infrastructure supporting such high availability takes numerous components and resources to function optimally. When an organization makes the decision to design a data center, they utilize resources to provide insight into what components to deploy. …

Reactive Exploration With Self-Reconfigurable Systems, Eric Fabricant

Theses

Modular self-reconfigurable robots (MSR) are robots composed of modules that translate over one another to permit reconfiguration and locomotion. This construction allows them to traverse a broader range of environments than legged or wheeled robots. MSR also posses the ability to split apart to parallelize their efforts or combine with each other to produce a larger robot capable of navigating more diverse terrain. In this paper we discuss a state-based reactive architecture for the distributed control of cooperative MSR teams in unknown environments. The MSR use local sensory data from the environment and a model of the team to select …

A Tale Of Two Debtors: Bankruptcy Disparities By Race, Rory Van Loo

Faculty Scholarship

This article offers the first quantitative evidence on race and bankruptcy. Minority debtors fare worse overall in bankruptcy — blacks are 40% and Hispanics 43% less likely than whites to receive a discharge in Chapter 13 after controlling for variables such as education, income, and employment. While the data do not allow for causal inference, Chapter 13 trustees were twice as likely to have made a motion to dismiss even against black debtors who ultimately completed their multi-year bankruptcy plans than against similar white debtors. The paper also indicates that a lack of attorney representation by minority debtors may make …

Judicial Control Of The National Labor Relations Board's Lawmaking In The Age Of Chevron And Brand X, Michael C. Harper

Faculty Scholarship

This article analyzes and applies to Labor Board decision making the Court’s oft-cited 1984 decision in Chevron U.S.A. v. Natural Resources Defense Council. The article argues that judicial review of Board decision making under Chevron, though limited, can still be sufficiently meaningful to control excessive shifts in Board lawmaking criticized by many commentators. The article explains why recent Supreme Court decisions reject any distinction between two theoretically distinct forms of agency discretionary lawmaking – (1) lawmaking through construction of the direct force of an ambiguous statute: and (2) lawmaking through the elaboration of law beyond that which is embodied in …

Building Intellectual Property Coalitions For Development, Peter K. Yu

Faculty Scholarship

The adoption of the WIPO Development Agenda in October 2007 has provided less developed countries with a rare and unprecedented opportunity to reshape the international intellectual property system in a way that would better advance their interests. However, if these countries are to succeed, they need to take advantage of the current momentum, coordinate better with other countries and nongovernmental organizations, and more actively share with others their experience, knowledge, and best practices.

Commissioned by the EDGE (Emerging Dynamic Global Economies) Network of the University of Ottawa, this paper begins by explaining how building intellectual property coalitions for development (IPC4D) …
