An Investigation Of The Effect Of Chassis Connections On Radiated Emi From Pcbs, N. Kobayashi, T. Harada, A. Shaik, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

This paper investigates the effect of grounding posts when printed circuit boards are mounted near and parallel to a metal plate or chassis. Specifically, experimental data showing changes in radiated emission levels are explained by means of coupling phenomena between a power bus, a chassis cavity including grounding posts, and a cable connected to the power bus. This coupling is modeled using SPICE and the results are combined with an equivalent magnetic current source model to estimate the radiated emissions from various printed circuit board configurations. the calculated results are shown to be consistent with the corresponding experimental data. © …

Emc Expert Systems For Evaluating Automotive Designs, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

The automobiles of the future are being designed on computers and a significant amount of performance and safety testing is done using computer models. by the time the first hardware prototype is built, many critical design decisions affecting intersystem and intra-system electromagnetic compatibility (EMC) have been made. Therefore, it is becoming increasingly important to perform the first EMC design review well before any hardware is available to test. Automotive EMC expert systems examine the relevant aspects of an automotive design while it is still on the computer to spot design features that are likely to cause EMC problems. © 2006 …

This paper describes a two-step technique for modeling the radiated electromagnetic emissions from a printed circuit board with attached cables when the source of the emissions is noise between the board's power and ground planes. the first step calculates the electric fields at the edges of the power-ground plane pair. the second step replaces the power plane with equivalent sources embedded within the ground plane structure. Examples are provided that demonstrate the accuracy of this approach. © 2006 IEEE.

Power System Control With An Embedded Neural Network In Hybrid System Modeling, Seung-Mook Baek, Jung-Wook Park, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

The output limits of the power system stabilizer (PSS) can improve the system damping performance immediately following a large disturbance. Due to non-smooth nonlinearities from the saturation limits, these values cannot be determined by the conventional tuning methods based on linear analysis. Only ad hoc tuning procedures can been used. A feedforward neural network (FFNN) (with a structure of multilayer perceptron neural network) is applied to identify the dynamics of an objective function formed by the states, and thereafter to compute the gradients required in the nonlinear parameter optimization. Moreover, its derivative information is used to replace that obtained from …

Predicting Load Harmonics In Three Phase Systems Using Neural Networks, Joy Mazumdar, Frank C. Lambert, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a artificial neural network (ANN) based method for the problem of measuring the actual harmonic current injected into a power system network by three phase nonlinear loads without disconnecting any loads from the network. The ANN directly estimates or identifies the nonlinear admittance (or impedance) of the load by using the measured values of voltage and current waveforms. The output of this ANN is a waveform of the current that the load would have injected into the network if the load had been supplied from a sinusoidal voltage source and is therefore a direct measure of load …

A Fault-Tolerant P-Q Decoupled Control Scheme For Static Synchronous Series Compensator, Wei Qiao, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Control of nonlinear devices in power systems relies on the availability and the quality of sensor measurements. Measurements can be corrupted or interrupted due to sensor failure, broken or bad connections, bad communication, or malfunction of some hardware or software (referred to as missing sensor measurements in this paper). This paper proposes a fault-tolerant control scheme (FTCS) for a static synchronous series compensator (SSSC). This FTCS consists of a sensor evaluation and (missing sensor) restoration scheme (SERS) cascaded with a P-Q decoupled control scheme (PQDC). It is able to provide effective control to the SSSC when single or multiple crucial …

Development And Implementation Of Optimized Energy-Delay Sub-Network Routing Protocol For Wireless Sensor Networks, Maciej Jan Zawodniok, Jagannathan Sarangapani, Steve Eugene Watkins, James W. Fonda

Electrical and Computer Engineering Faculty Research & Creative Works

The development and implementation of the optimized energy-delay sub-network routing (OEDSR) protocol for wireless sensor networks (WSN) is presented. This ondemand routing protocol minimizes a novel link cost factor which is defined using available energy, end-to-end (E2E) delay and distance from a node to the base station (BS), along with clustering, to effectively route information to the BS. Initially, the nodes are either in idle or sleep mode, but once an event is detected, the nodes near the event become active and start forming sub-networks. Formation of the inactive network into a sub-network saves energy because only a portion of …

Distributed Power Control For Cellular Networks In The Presence Of Channel Uncertainties, Maciej Jan Zawodniok, Q. Shang, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel distributed power control (DPC) scheme for cellular network in the presence of radio channel uncertainties such as path loss, shadowing, and Rayleigh fading is presented. Since these uncertainties can attenuate the received signal strength and can cause variations in the received Signal-to-Interference ratio (SIR), a new DPC scheme, which can estimate the slowly varying channel uncertainty, is proposed so that a target SIR at the receiver can be maintained. Further, the standard assumption of a constant interference during a link's power update used in other works in the literature is relaxed. A CDMA-based cellular network …

Gene Expression Data For Dlbcl Cancer Survival Prediction With A Combination Of Machine Learning Technologies, Rui Xu, Xindi Cai, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

Gene expression profiles have become an important and promising way for cancer prognosis and treatment. In addition to their application in cancer class prediction and discovery, gene expression data can be used for the prediction of patient survival. Here, we use particle swarm optimization (PSO) to address one of the major challenges in gene expression data analysis, the curse of dimensionality, in order to discriminate high risk patients from low risk patients. A discrete binary version of PSO is used for gene selection and dimensionality reduction, and a probabilistic neural network (PNN) is implemented as the classifier. The experimental results …

Intelligent Optimal Control Of Excitation And Turbine Systems In Power Networks, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

The increasing complexity of the modern power grid highlights the need for advanced modeling and control techniques for effective control of excitation and turbine systems. The crucial factors affecting the modern power systems today is voltage control and system stabilization during small and large disturbances. Simulation studies and real-time laboratory experimental studies carried out are described and the results show the successful control of the power system excitation and turbine systems with adaptive and optimal neurocontrol approaches. Performances of the neurocontrollers are compared with the conventional PI controllers for damping under different operating conditions for small and large disturbances.

Laser Optical In-Circuit Measurement System For Immunity Applications, Chong Ding, David Pommerenke

Electrical and Computer Engineering Faculty Research & Creative Works

During immunity testing (ESD, EFT) of a digital circuit, the waveforms of critical signal nets need to be measured for analyzing the failure mechanism. However, it is difficult to measure the induced voltage in the circuit under test due to the unwanted coupling by the non-ideal shielding of the probe cable, especially, if large common mode currents are present. Fiber optical connection avoids this problem. Semiconductor lasers have frequently been used for converting the voltage into an optical signal. The paper shows novel implementations of powering the laser, leading to a small, low cost optical probe.

Static Var Compensator (SVC) are employed for providing better voltage regulation and transient stability especially for increased power transfer through the transmission lines. In this paper, two SVC damping controllers with single and dual inputs respectively are designed based on wide area measurements of generator speed deviations. A Small Population based Particle Swarm Optimization algorithm (SPPSO) is applied to determine the optimal parameters of the damping controllers for small and large disturbances. Simulation results are provided to show that the effectiveness of the optimal damping controllers on the Kundur''s two-area benchmark power system. Results show the dual input controller further …

Particle Swarm Optimization Based Defensive Islanding Of Large Scale Power System, Wenxin Liu, Ganesh K. Venayagamoorthy, David A. Cartes

Electrical and Computer Engineering Faculty Research & Creative Works

Defensive islanding is an efficient way to avoid catastrophic failures and wide area blackouts. Power system splitting especially for large scale power systems is a combinatorial explosion problem. Thus, it is very difficult to find an optimal solution (if one exists) for large scale power system in real time. This paper proposes to utilize the computational efficiency property of Binary Particle Swarm Optimization (BPSO) to find some efficient splitting solutions in limited timeframe. The solutions are optimized based on a cost function considering the balance between real power generation and consumption, the relative importance of customers, the capacities of distribution …

Real-Time Implementation Of A Statcom On A Wind Farm Equipped With Doubly Fed Induction Generators, Wei Qiao, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Voltage stability is a key issue to achieve the uninterrupted operation of wind farms equipped with doubly fed induction generators (DFIGs) during grid faults. A Static Synchronous Compensator (STATCOM) is applied to a power network which includes a DFIG driven by a wind turbine, for steady state voltage regulation and transient voltage stability support. The control schemes of the DFIG rotor-side converter, grid-side converter and the STATCOM are suitably designed and coordinated. The system is implemented in real-time on a Real-Time Digital Simulator (RTDS®). Results show that the STATCOM improves the transient voltage stability and therefore helps the wind turbine …

Edmund Burke, John Whyte And Themes In Canadian Constitutional Culture, David Schneiderman

Georgetown Law Faculty Publications and Other Works

John Whyte, the author observes, is committed to the idea that there are moral foundations to Canada's constitutional order and that these foundations are derived from liberal principles. This paper compares Whyte's liberal and organicist constitutionalism to that of the eighteenth century British political thinker, Edmund Burke. Three themes are predominant in Whyte's work: those of liberty and security, unity and diversity, and constitutional change. Drawing out these themes in both Whyte's and Burke's constitutional thought, the author argues that Whyte has a sound historical basis for deriving Canadian constitutional practices from liberal principles ordinarily associated with Burke. The author …

Defending The Unpopular Down-Under, Abbe Smith

Georgetown Law Faculty Publications and Other Works

The ethics of criminal defence lawyers and others who represent 'unpopular clients' is a largely unexplored area of legal scholarship in Australia. This article seeks to examine, from a comparative perspective, the motivations and ethical practices of these lawyers. Using interviews with Australian lawyers who represent the criminally accused, prisoners and asylum-seekers, as well as relevant ethical rules and commentary, the article identifies why lawyers undertake unpopular cases and, ultimately, what sustains them. Contrasting Australian legal practice with that in the US, the article discusses the sometimes competing professional obligations to court and client, truth and advocacy, public and profession. …

The Story Of Upjohn Co. V. United States: One Man's Journey To Extend Lawyer-Client Confidentiality, And The Social Forces That Affected It, Paul F. Rothstein

Georgetown Law Faculty Publications and Other Works

The attorney-client privilege protects information a client provides an attorney in confidence for the purpose of securing legal advice. But suppose the client is not a person but a corporation and can only speak through its agents and employees. What then are the contours of the privilege? If the corporation's attorney asks an employee for information relating to pending litigation or other legal matters, is the conversation privileged? Some courts said that no communications to a corporate attorney were privileged unless they came from members of the corporate control group, loosely those people who had authority to direct the attorney's …

Masters Theses

"This study represents a contribution to Early Paleogene biostratigraphy in the tropics where published studies are sparse in comparison with mid and high latitude regions. Data were derived from a comprehensive analysis of dinoflagellate cysts (dinocysts) in 45 samples from the Early Paleocene to Early Eocene interval at two localities in West Africa, namely Alo-1 well in the Anambra Basin, southeastern Nigeria, and Ocean Drilling Program Hole 959D (ODP Leg 159) in the Cote d'Ivoire-Ghana Transform Margin. Dinocyst recovery varied from very good to poor, and the specimens were commonly well preserved. The dinocyst data were calibrated with existing calcareous …

Model Checking Control Communication Of A Facts Device, David Andrew Cape

Masters Theses

"This thesis concerns the design and verification of a real-time communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to design and verify the correctness in the presence of these lost data frames under real-time constraints. This thesis describes a temporal verification that if the end processes do not detect that too many frames are lost, defined by comparison of error counters against given threshold values, then there will be a bounded delay between transmission of …
