Performance Evaluation Of Video Streaming With Background Traffic Over Ieee 802.11 Wlan Networks, Nicola Cranley, Mark Davis

Conference papers

There is an increasing demand for multimedia streaming applications over WLAN networks. MPEG-4 and H.264 are compression standards targeted at high-quality streamed multimedia services over wireless best-effort IP networks. However, the dynamic nature of wireless networks in terms of fluctuating bandwidth and time-varying delays makes it difficult to provide good quality streaming under such constraints. Multimedia streaming applications are a demanding and challenging service to deliver over wireless networks. There is a trade-off between the capacity of the wireless network and the quality of the multimedia streaming application. In this paper we investigate the effect the background traffic load has …

Economic Costs Of Low Safety Belt Usage In Motor Vehicle Crashes In Kentucky, Michael Singleton, Qing Xiao, Kenneth R. Agent

Kentucky Transportation Center Research Report

By passing legislation in 2006 to mandate primary enforcement of the Kentucky state law requiring safety belt use for motor vehicle occupants, the state could expect to realize an overall savings of at least $118 million in direct medical costs over the ten-year period from 2006 to 2015. Charges to Medicaid over that period would be about $34 million less than under the current secondary enforcement model. In addition, there would be at least $67 million saved in medical costs to commercial insurers, $2.3 million to Medicare, $3.3 million to Worker’s Compensation, and $11.2 million to other sources.

These savings …

Phase Stability Analysis Using Interval Newton Method With Nrtl Model, Hatice Gecegormez, Yaşar Demirel

Papers in Fluid Mechanics

The Gibbs energy minimization using activity coefficient models and nonlinear equation solution techniques are commonly applied for phase stability problems. However, dependence on the initial estimates and multiple solutions for these highly nonlinear equations are common drawbacks for some of the conventional approaches. We have used interval Newton method with the local composition model of NRTL for the phase stability analysis of 10 binary systems and 2 ternary systems at various feed compositions to locate all the stationary points. Results indicate that the interval Newton method is reliable and efficient.

Repeatable Nanostructures In Dielectrics By Femtosecond Laser Pulse Trains, Lan Jiang, Hai-Lung Tsai

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Using the plasma model recent developed by the authors, this study predicts the existence of a constant ablation-depth zone with respect to fluence in femtosecond laser ablation of dielectrics, which has also been observed experimentally. It is found that the value of the constant ablation depth is significantly decreased by the pulse train technology. Repeatable nanostructures can be achieved with the parameters in the constant ablation-depth zone of a femtosecond pulse train, even when the laser system is subject to fluctuations in fluences.

Upfc Control Employing Gradient Descent Search, William M. Siever, Radha P. Kalyani, Mariesa Crow, Daniel R. Tauritz

Electrical and Computer Engineering Faculty Research & Creative Works

Increasing demand coupled with limitations on new construction indicate that existing power transmission must be better controlled in order to continue reliable operation. Recent advances in FACTS devices provide a mechanism to better control power flow on the transmission network. One particular device, the unified power flow controller (UPFC), holds the most promise for maintaining operation even when the system has suffered partial failure (either naturally occurring, due to human error, or a malicious attack). In addition to the capital cost, the primary obstacles to widespread UPFC use are the combined problems of selecting the most cost effective locations for …

Application Of Transmission Line Models To Backpanel Plated Through-Hole Via Design, Shaowei Deng, Todd H. Hubing, James L. Drewniak, Jun Fan, James L. Knighten, Norman W. Smith

Electrical and Computer Engineering Faculty Research & Creative Works

This paper introduces an approach of using a plated through-hole (PTH) via transmission-line model in the design of a thick printed circuit board, such as a backpanel. Full wave FEM modeling of a section of backpanel containing a differential via pair was compared with a transmission model. Computed values of the differential transmission loss agreed within an acceptable range for engineering studies, yet the transmission line model results required less than 2% of the computation time that the full wave model required. Effects of via spacing, via diameter and trace thickness were also examined.

Voltage Regulator Module Noise Analysis For High-Volume Server Applications, Erdem Matoglu, N. Pham, Giuseppe Selli, Mauro Lai, Samuel R. Connor, James L. Drewniak, Bruce Archambeault, D. Wang, D. Kuhn, R. Hashemi, Daniel N. De Araujo, M. Cases, B. Wilkie, B. Herrman, P. Patel

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a methodology to analyze voltage regulator module (VRM) noise coupling problems in high-volume server applications. The technique is applied on a real engineering design. The comprehensive model includes irregular power shapes, decoupling capacitors, and dielectric and conductive loss. Irregular shaped power plane modeling is cross-checked with four separate methods to demonstrate accuracy.

Complex Power Distribution Network Investigation Using Spice Based Extraction From First Principle Formulations, Giuseppe Selli, James L. Drewniak, Richard E. Dubroff, Jun Fan, James L. Knighten, Norman W. Smith, Dean Mccoy, Bruce Archambeault, Stefano Grivet-Talocia, Flavio G. Canavero

Electrical and Computer Engineering Faculty Research & Creative Works

The modeling and the analysis of the power distribution networks (PDN) within multi-layer printed circuit board is crucial for the investigation of the performance of PCB systems. Carrying out such analyses in SPICE based tools has the advantage of being faster than the corresponding full-wave modeling and it allows obtaining both frequency and time domain results.

Control Interaction Mitigation For The Unified Power Flow Controller, Liangying Dong, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

This paper establishes that dynamic interactions can occur between multiple UPFCs installed in power systems. The existence of the dynamic interactions can adversely affect the overall system performance and lead to system instability. This paper identifies two types of interactions among FACTS controllers: low frequency inter-area interaction and high frequency controller interactions. Several control approaches are proposed to mitigate these interactions. The IEEE New England 10-machine 39-bus system is used to demonstrate the existence of the control interactions and illustrate the effectiveness of the proposed interaction mitigation controls.

Association Between Lower Extremity Posture At Contact And Peak Knee Valgus Moment During Sidestepping: Implications For Acl Injury, Scott G. Mclean, Xuemei M. Huang, Antonie J. Van Den Bogert

Mechanical Engineering Faculty Publications

Background. Knee valgus load during sports movement is viewed as an important predictor of non-contact anterior cruciate ligament injury risk, particularly in females. Formulating movement strategies that can reduce valgus loading during these movements therefore appears pertinent to reducing anterior cruciate ligament injury rates. With this in mind, the current study examined the relationship between peak valgus moment and lower extremity postures at impact during a sidestep cutting task.

Methods. Ten male and ten female NCAA athletes had initial contact three-dimensional hip, knee and ankle angles and subsequent knee valgus moment quantified during the execution of (n=10 trials) …

Cs 410/610: Theoretical Foundations Of Computing, Thomas Sudkamp

Computer Science & Engineering Syllabi

This course is an introduction to one of the fundamental topics in the theory of computer science: computability theory. Computability theory is concerned with determining whether there is an algorithmic solution to a problem. The study of computability uses the Turing machine as the basic computational model. A Turing machine is a random access, read-write, finite state automaton. The Church-Turing thesis asserts that any problem that can be solved in any algorithmic manner can be solved by a Turing machine.
