On Discrete-Time Modeling Of Time-Varying Wssus Fading Channels, Christian Sgraja, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we consider the serial concatenation of linear time-varying (LTV) systems and its impact on the discrete-time modeling of wide-sense stationary uncorrelated scattering (WSSUS) fading channels. By deriving an expression for the composite impulse response of the overall concatenated system, we find that unlike the time-invariant case, the concatenation of LTV systems is not commutative, i. e., the order of arrangement affects the overall impulse response. This has significant impact when a digital transmission over a time-varying fading channel, which is an LTV channel, is represented by an equivalent discrete-time model that incorporates both transmitter and receiver filters. …

Decentralized Power Control With Implementation For Rfid Networks, Kainan Cha, Anil Ramachandran, David Pommerenke, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In radio frequency identification (RFID) systems, the detection range and read rates will suffer from interference among high power reading devices. This problem grows severely and degrades system performance in dense RFID networks. In this paper, we investigate a suite of feasible power control schemes to ensure overall coverage area of the system while maintaining a desired read rate. The power control scheme and MAC protocol dynamically adjusts the RFID reader power output in response to the interference level seen locally during tag reading for an acceptable signal-to-noise ratio (SNR). We present novel distributed adaptive power control (DAPC) and probabilistic …

Electrical and Computer Engineering Faculty Research & Creative Works

The SMART system is a special purpose server developed by ETRI and designed for efficient streaming services over high speed networks. The SMART server has one or more special purpose NS (Network-Storage) card. The NS card has several disks that store multimedia contents. However all of the multimedia contents to be serviced cannot be stored at the server. In this paper, we will describe the storage management mechanism in design and implementation aspects. With this storage management mechanism, the SMART server can provide effectiveness in managing storage and distributing some contents from a source station to streaming service servers.

Critical systems are aptly named - from electric power to water and gas to the telephone system and the Internet, they're all critical to some aspect of our daily lives. We''re a networked society and as such, it's important to both know whether critical systems are trustworthy and be able to communicate, review, and debate the level of trust achieved in them. In the safety domain, explicit safety cases are increasingly required by law, regulations, and standards. In this article, we outline what a small, international group of experts, spanning various disciplines in safety, security, reliability, and critical infrastructure, been …

Adaptive And Probabilistic Power Control Algorithms For Dense Rfid Reader Network, Kainan Cha, Anil Ramachandran, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In radio frequency identification (RFID) systems, the detection range and read rates may suffer from interferences between high power devices such as readers. In dense networks, this problem grows severely and degrades system performance. In this paper, we investigate feasible power control schemes to ensure overall coverage area of the system while maintaining a desired data rate. The power control should dynamically adjust the output power of a RFID reader by adapting to the noise level seen during tag reading and acceptable signal-to-noise ratio (SNR). We present a novel distributed adaptive power control (DAPC) and probabilistic power control (PPC) as …

Comparison Of Two Optimal Control Strategies For A Grid Independent Photovoltaic System, Richard L. Welch, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents two optimal control strategies for a grid independent photovoltaic system consisting of a PV collector array, a storage battery, and loads (critical and non-critical loads). The first strategy is based on Action Dependent Heuristic Dynamic Programming (ADHDP), a model-free adaptive critic design (ACD) technique which optimizes the control performance based on a utility function. ADHDP critic network is used in a PV system simulation study to train an action neural network (optimal neurocontroller) to provide optimal control for varying PV system output energy and loadings. The second optimal control strategy is based on a fuzzy logic controller …

Iep Meetings: What Are The Strategies That Make An Iep Meeting Successful?, Maria T. Cashman

Dissertations and Theses @ UNI

All students who receive special education services have one thing in common. They each have an Individualized Education Plan (IEP) designed specifically for him/her. The IEP is a valuable document that guides the special education services for a student. It is imperative that parents have a significant role in the development, implementation, and review of the IEP.

For this study, interviews were used to understand the strategies that assist parents in achieving active participation during their child's IEP conference. Six parents of sophomore, junior, and senior high students were interviewed. Three parents were identified as "involved", which means they were …

Robustness And Distance Discrimination Of Adaptive Near Field Beamformers, Y. Rosa Zheng, Peng Xie, Steven L. Grant

Electrical and Computer Engineering Faculty Research & Creative Works

A robust adaptive beamformer is proposed using the near field regionally constrained adaptive approach that designs a set of linear constraints by filtering on a low rank subspace of the near field signal over a spatial region and a wide frequency band. This method can accurately control the beam-former response over the designed spatial-temporal region using a small number of linear constraint vectors and improve the robustness against target location errors. Meanwhile, this method enhances the capability of the near field beamformer in distance discrimination without additional constraints so that interference impinging at the same direction as the desired signal …

Children Experiencing Parental Incarceration: An Examination Of Literature And Supportive Programming, Telisa A. Burt

Graduate Research Papers

Parental incarceration is becoming an increasing relevant topic as American society continues in its tendency toward mass incarceration. As mandatory minimums send away criminals for longer periods of time, it also serves as a major cause behind parent-child separation. In the United States, it is estimated that there are over 1.5 million children with at least one incarcerated parent and about 7 million children with a parent under some form of correctional supervision. According to research, these children are more likely to become incarcerated and many are expected to experience either juvenile or adult incarceration in their lifetime. This study …

Effects Of Trait Anxiety And Cognitive Appraisals On Emotional Reactions To Psychological And Physical Stressors, Qutayba Abdullatif

USF Tampa Graduate Theses and Dissertations

This study investigated the effects of individual differences in trait anxiety on cognitive appraisals and emotional reactions to stressful situations. Specifically, the effects of trait anxiety on the evaluation of psychological and physical threats to well-being were examined in relation to state-anxiety. To accomplish this goal, a proposed model consisting of elements from the Lazarus and Folkman Stress and Coping Model (1984) and Spielberger's State Trait distinctions is presented. To our knowledge, this is the first proposed model to attempt to combine trait anxiety, primary and secondary appraisals, and state anxiety and to utilize path analytic models in assessing empirical …

Another Paradise Lost? : A Case Study Of Nation Building In East Timor, Brendan Paul Mcshanag

Theses : Honours

This thesis examines the form of reconstruction intervention known as 'nation building', through a case study of the United Nations led operation in East Timor that began in 1999. It examines how the idea of the nation and statehood first arose, and how these ideals are still prevalent in modern nation building interventions. The thesis also examines the weaknesses and ambiguities that have become associated with nation building, and how such weaknesses have found a common thread through subsequent interventions The thesis then uses the case study of the intervention in East Timor, dividing the operation in to three stages; …

The Art Of Trash: Evaluating Troma Entertainment As Paracinema, James W. Macdonald

Theses : Honours

The aim of this research is to explore the anti-establishment function of the work of Lloyd Kaufman and his film studio, Troma Entertainment. The research focuses on Troma's capacities as paracinema, and examines how in relishing their derided position in the cultural field, Lloyd Kaufman's films represent an anti-establishment cinematic form, combating an institutionalised idea of cultural value. Through challenging the rules of taste, Lloyd Kaufman's films serve to push the boundaries of what is considered valuable in contemporary culture. Films that revel in their 'bad taste' through extreme themes, poor humour and amateurism, make a stand against the mainstream …

Finding The Watermark: A Filmic Response To Domestic Abuse Within Australian Film From 1970 - 2006, Erin Nichols

Theses : Honours

Due to various social, international and economic encumbrances, Australian film has made a limited foray into the representation of domestic abuse. A limited number of films have been made on this topic since the early 1970's, and even then, the depiction of this social issue has been watered down and sanitised for mainstream consumption. It is the author's belief that the filmmaker has an important and highly influential opportunity to present a social commentary on issues and must not shirk that responsibility. The film project supported by this exegesis responds to the above concerns and the priority has been to …

Taiwan's Wto Membership And Its International Implications, Steve Charnovitz

GW Law Faculty Publications & Other Works

In contrast to other international organizations, the World Trade Organization does not require its members to be states. This constitutional feature has allowed Taiwan to join the WTO alongside China. As a result, the WTO is now the only major international organization in which Taiwan can participate as a full member. This article explores some implications of this unique situation for Taiwan, for the WTO, and for international law. The article contends that Taiwan's membership in the WTO is not itself a bilateral treaty with China and does not itself change the legal relationship between Taiwan and China. What Taiwan's …

The Relevance Of The Nlra And Labor Organizations In The Post-Industrial Global Economy, Charles B. Craver

GW Law Faculty Publications & Other Works

As the United States continues to transition from a manufacturing to a post-industrial service-oriented economy that is directly affected by global competition, the strength of domestic labor organizations has declined and private sector union membership has fallen to below 8 percent. Most unions continue to behave like the craft and industrial organizations of the mid-1900s. They employ appeals that once worked well for blue collar manufacturing workers to appeal to new-age white collar and service personnel who view traditional unionization as working class. If labor organizations hope to appeal to twenty-first century employees, they must devise strategies that will resonate …

Too Big To Fail: Moral Hazard In Auditing And The Need To Restructure The Industry Before It Unravels, Lawrence A. Cunningham

GW Law Faculty Publications & Other Works

Large audit firms may believe that they are too big to fail. Arthur Andersen's 2002 criminal indictment reduced their number from five to four, and the government decided in 2005 to avoid indicting KPMG for crimes it admitted committing. If audit firms interpret the government's reluctance to indict as signaling aversion to tough action against them, moral hazard arises. This offsets auditing improvements mandated by the Sarbanes-Oxley Act of 2002 that are designed to strengthen auditors' reputations with managers for thoroughness and improve financial statement reliability. Neutralizing this moral hazard requires a credible alternative industry structure so that when a …

Language, Deals And Standards: The Future Of Xml Contracts, Lawrence A. Cunningham

GW Law Faculty Publications & Other Works

eXtensible Markup Language (XML) structures information in documentary systems ranging from financial reports to medical records and business contracts. XML standards for specific applications are developed spontaneously by self-appointed technologists or entrepreneurs. XML's social and economic stakes are considerable, especially when developed for the private law of contracts. XML can reduce transaction costs but also limit the range of contractual expression and redefine the nature of law practice. So reliance on spontaneous development may be sub-optimal and identification of a more formal public standard setting model necessary. To exploit XML's advantages while minimizing risks, this Article envisions creating a publicly …

Public Law Values In A Privatized World, Laura T. Dickinson

GW Law Faculty Publications & Other Works

Although domestic administrative law scholars have long debated privatization within the US, this debate has not confronted the growing phenomenon of privatization in the international realm or its impact on the values embodied in public international law. Yet, with both nation-states and international organizations increasingly privatizing foreign affairs functions, privatization is now as significant a phenomenon internationally as it is domestically. For example, states are turning to private actors to perform core military, foreign aid, and diplomatic functions. Military privatization entered the popular consciousness in 2004, when private contractors working for the US government abused detainees at Abu Ghraib prison …
