An Architectural Framework For Performance Analysis: Supporting The Design, Configuration, And Control Of Dis /Hla Simulations, David B. Cavitt

Computer Science Theses & Dissertations

Technology advances are providing greater capabilities for most distributed computing environments. However, the advances in capabilities are paralleled by progressively increasing amounts of system complexity. In many instances, this complexity can lead to a lack of understanding regarding bottlenecks in run-time performance of distributed applications. This is especially true in the domain of distributed simulations where a myriad of enabling technologies are used as building blocks to provide large-scale, geographically disperse, dynamic virtual worlds. Persons responsible for the design, configuration, and control of distributed simulations need to understand the impact of decisions made regarding the allocation and use of the …

The purpose of this research was to develop a parametric cost model for predicting operating costs of Army ground combat weapon systems. The model is intended to be used during the first two phases of the Army's acquisition process. The research necessary to develop the model was guided by two questions: what weapon system characteristics (such as weight, horsepower, fuel consumption, primary mission, NBC protection, fire control and night fighting capability) impact directly on operating ground combat systems; and what is the form of the parametric model for operating costs for ground combat systems? The study extends the bounds of …

Piezoceramic Actuator Placement For Acoustic Control Of Panels, Jeffrey S. Bevan

Mechanical & Aerospace Engineering Theses & Dissertations

Optimum placement of multiple traditional piezoceramic actuators is determined for active structural acoustic control of flat panels. The structural acoustic response is determined using acoustic radiation filters and structural surface vibration characteristics. Linear Quadratic Regulator (LQR) control is utilized to determine the optimum state feedback gain for active structural acoustic control. The optimum actuator location is determined by minimizing the structural acoustic radiated noise using a modified genetic algorithm. Experimental tests are conducted and compared to analytical results.

Anisotropic piezoceramic actuators exhibit enhanced performance when compared to traditional isotropic piezoceramic actuators. As a result of the inherent isotropy, these advanced …

Tuning Parameter Tolerance Design: Foundations, Methods, And Measures, Daniel A. Mcadams, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper, a novel technique is presented to solve tolerance design problems. To achieve the desired performance tolerance, the technique uses a subtle, but significant, change in the design: the addition of a tuning parameter in place of an increase in component precision. Statistical models are used to develop a framework for the tuning parameter design method. Also developed is a new, dimensionless design metric which ranks candidate tuning parameters. A step-by-step method is developed for the application of tuning parameters using this metric. The step-by-step tuning parameter design method is applied to a heavy-duty manual stapler as a …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background quantities of trace elements were surveyed in Major Land Resource Area 126, the Central Appalachian Plateau in northwestern West Virginia. Three pedons each of Upshur, Vandalia, (both Typic Hapludalfs) and Gilpin (Typic Hapludult) soils were described and sampled in Doddridge, Mason and Clay counties. Twelve trace elements were extracted from soil samples by the EPA 3051 and hydrofluoric acid methods. The data from both procedures showed that except for Ca and Mg, the HF method extracted greater quantities of trace elements than EPA Method 3051. Significant differences were found for all trace elements except Cd, Cr, and Pb. Calcium, …

A Model To Predict The Long-Term Strength Of E-Glass Fiber Composites Subjected To Environmental Exposure., Thomas Miles Damiani

Graduate Theses, Dissertations, and Problem Reports (ETD)

Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degrade the strength of an FRP composite, potentially negating the advantages of their use. This research sought to develop a theoretical model to predict the long-term strength of an FRP composite subjected to environmental exposure. Degradation models for the reinforcement fibers and the interphase region were developed and verified using existing data. The two constituent models were combined through the modification …

A Droplet Formation And Entrainment Model For Stratified Liquid-Liquid Flows., Allen Elton Badeau Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Droplet formation is a common phenomenon that occurs in liquid-liquid or liquid-gas two-phase flows where turbulent mixing is present. This study considers only liquid-liquid systems and presents the theoretical background and validation of a droplet formation and entrainment (DFE) model with application to stratified shear layer flows of diesel fuel and water. A parallel experimental study by Wu and Katz (1999) of the same flow is used as a guide in our analysis. The new Droplet Formation and Entrainment Model, DFE, is based on a previous DFE model [Wilson, W. (1999)] which used the gradient Richardson number, Rig, as the …

The Fracture Analysis And Remaining Life Estimation Of The Avlb Sub-Components., Jeong-Hoon Choi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Armored Vehicle Launch Bridge (AVLB) is subjected to cyclic loading during its launching as well as tank crossing. The cyclic loading causes crack to initiate in critical bridge components, and to propagate. Unless these cracks are detected and repaired before they rapidly grow to reach their critical stage of propagation, the failure of bridge components can occur. According to the Preventive Maintenance Checks and Services (PMCS) from the U.S. Army, three AVLB components, the splice doubler angle, the splice plate, and the bottom chord, are susceptible to fatigue damage. In the present study, the laboratory fatigue tests on the …

Whole-Body Vibration And The Lower Back: The Effect Of Whole-Body Vibration On Pain In The Lower Back., Erik W. Gregory

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study utilized six subjects from the West Virginia University Motor pool, whose exposure to whole-body vibrations were measured and reported as root mean squared (r.m.s.) values in accordance with ISO standard 2631. Each subject completed a questionnaire regarding their general health, and specifically whether they experienced low back pain, and if so, the extent and severity of this pain. It was expected that the individuals subjected to the highest vibration levels would tend to report LBP, with severity of pain increasing with the intensity of exposure. This study did not support that belief. However, it may be that chronic …

Modelling And Control Of The Unified Power Flow Controller (Upfc)., Azra Hasanovic

Graduate Theses, Dissertations, and Problem Reports (ETD)

The focus of this thesis is a FACTS device known as the Unified Power Flow Controller (UPFC). With its unique capability to control simultaneously real and reactive power flows on a transmission line as well as to regulate voltage at the bus where it is connected, this device creates a tremendous quality impact on power system stability. These features become even more significant knowing that the UPFC can allow loading of the transmission lines close to their thermal limits, forcing the power to flow through the desired paths. This will give the power system operators much needed flexibility in order …

Use Of Track-Etched Polycarbonate Filters In Series To Mimic The Total Human Lung Deposition In The Ultrafine And Fine Particle Range From 0.03 To 0.40 Microns., Jennifer Lynn Hornsby-Myers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three 3.0m polycarbonate track-etched filters were used in series in a 37 mm cassette and tested at 2.2 L/min using an automated filter tester to determine the filter assembly’s deposition curve as a function of particle size from 0.03 to 0.4 m. The filter assembly’s efficiency curve was compared to Stahlhofen’s resting with nose breathing and working with mouth breathing human total lung deposition curves used by the ICRP. Bias maps show that the shape of the filter assembly’s deposition curve matches the two lung deposition curves in the ultrafine range under these specific test conditions. The efficiency curve of …

The Role Of Lois Marie Gibbs In The Love Canal Crisis And Its Effect On Federal "Superfund" Legislation, 1973-1981., Daniel Victor Kahler

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the spring of 1978, a young homemaker named Lois Marie Gibbs discovered that her child was attending an elementary school built on top of a 20,000 ton, toxic chemical dump in Niagara Falls, New York. Out of desperation, she organized her neighbors into the Love Canal Homeowners Association and struggled more than two years for relocation. Opposing the group’s efforts were the chemical manufacturer, Hooker Chemical Corporation, and local, state, and federal government officials who insisted that the leaking toxic chemicals, including dioxin the most toxic chemical known to man, was not the cause of high rates of birth …

Data Points Or Cultural Entities: A Gis-Based Archaeological Predictive Model In A Post-Positivist Framework., Linwood Jesse Rouse

Graduate Theses, Dissertations, and Problem Reports (ETD)

Archaeological predictive models have been used in conjunction with sampling strategies, in large scale archaeological surveys, for over thirty years. During this time, these models have undergone many conceptual and theoretical changes. Archaeological predictive models stemmed from the positivist Processual Archaeology, but the shift from positivism has precipitated the need to reconsider the ideas from which they are based. There is a general trend within the current spectrum of ideologies to support the importance of cultural information in archaeological research. The following research contends that cultural information has not been utilized to its full extent in archaeological models and that …
