Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey

Theses and Dissertations

It is an undisputable fact that most systems, upon consistence usage are bound to fail in the performance of their intended functions at a point in time. When this occurs, various strategies are set in place to restore them back to a satisfactory performance. This may include replacing the failed component with a new one, swapping parts, resetting adjustable parts to mention but a few. Any such system is referred to as a repairable system. There is the need to study these systems and use statistical models to predict their failing time and be able to set modalities in place …

Controlling Steam Flood Migration With Air Injection Wells, Rex Hodges

All Dissertations

Steam flooding is an aggressive remediation technology for removing volatile organic chemical (VOC) sources that slowly dissolve into passing groundwater. Plume concentrations can be reduced, accelerating cleanup, and decreasing plume management costs. Steam injected in wells surrounding the source spreads outward and develops into a front that drives contamination to a system of groundwater pumping wells in the saturated zone and soil vapor extraction wells in the vadose zone. The process can be modeled with the non-isothermal multi-phase flow simulator T2VOC to include operation designs and factors at individual sites.

Visualization Of Polymer Processing At The Continuum Level, Jeremy Hicks

All Theses

Computer animation, coupled with scientific experimentation and modeling, allows scientists to produce detailed visualizations that potentially enable more comprehensive perception of physical phenomena and ultimately, new discoveries. With the use of Maya, an animation and modeling program that incorporates the natural laws of physics to control the behavior of virtual objects in computer animation, data from the modeling of physical processes such as polymer fibers and films can be explored in the visual realm. Currently, few attempts have been made at the continuum level to represent polymer properties via computer animation using advanced graphics. As a result, scientists may be …

A Bayesian Perspective On Estimating Mean, Variance, And Standard-Deviation From Data, Travis E. Oliphant

Faculty Publications

This article shows how to compute confidence intervals for mean, standard-deviation, and variance using Bayesian methods. The method is implemented in SciPy as scipy.stats.bayes_mvs After reviewing some classical estimators for mean, variance, and standard-deviation and showing that un-biased estimates are not usually desirable, a Bayesian perspective is employed to determine what is known about mean, variance, and standard deviation given only that a data set in-fact has a common mean and variance. Maximum-entropy is used to argue that the likelihood function in this situation should be the same as if the data were independent and identically distributed Gaussian. A non-informative …

Suboptimal Feedback Control Design Of Constrained Parabolic Systems In Uncertainty Conditions, Boris S. Mordukhovich

Mathematics Research Reports

The paper concerns minimax control problems forlinear multidimensional parabolic systems with distributed uncertain perturbations and control functions acting in the Dirichlet boundary conditions. The underlying parabolic control system is functioning under hard/pointwise constraints on control and state variables. The main goal is to design a feedback control regulator that ensures the required state performance and robust stability under any feasible perturbations and minimize an energy-type functional under the worst perturbations from the given area. We develop an efficient approach to the minimax control design of constrained parabolic systems that is based on certain characteristic features of the parabolic dynamics including …

Mapping The Consensual Knowledge Of Security Risk Management Experts, David J. Brooks

Australian Information Warfare and Security Conference

The security industry comprises of diverse and multidisciplined practitioners, originating from many disciplines. It has been suggested that the industry has an undefined knowledge structure, although security experts contain a rich knowledge structure. There has also been limited research mapping security expert knowledge structure, reducing the ability of tertiary educators to provide industry focused teaching and learning. The study utilized multidimensional scaling (MDS) and expert interviews to map the consensual knowledge structure of security experts in their understanding of security risk. Security risk concepts were extracted and critiqued from West Australian university courses. Linguistic analysis categorised the more utilized security …

Clicking Away The Competition: The Legal Ramifications Of Click Fraud For Companies That Offer Pay Per Click Advertising Services, Daniel L. Hadjinian

Washington Journal of Law, Technology & Arts

Two businesses that advertise online, Lane's Gifts and Collectibles and Advanced Internet Technologies, recently filed lawsuits against Google, and other intermediaries that offer sponsored advertising services. The companies allege that these intermediaries failed to adequately protect them against "click fraud." Click fraud refers to the practice whereby competitors and other persons may click to view an online ad with no intention of buying, learning about the advertiser's services, or engaging in any other action that the ad aims to achieve. Plaintiffs allege that the intermediaries breached their contractual duties by charging the companies whose ads they hosted for fraudulent clicks, …

Unsupervised Neural Pattern Classifiers For Oral Vowel Pronunciation Of Foreign-Accented Speech, Joseph Hecker

All Theses

This thesis describes the development of unsupervised neural-based pattern classifiers for the training of vowel pronunciations for students learning a foreign language. This paper examines American learners of the French language. A corpus of single word utterances is compiled from a group of native French speakers. Cepstral features are used to train two unsupervised neural pattern classifiers: a self-organizing map and a growing neural gas. The development and justification for the use of these classifiers is presented. The output from the classifier is translated to a bar graph for visual assessment. The degree to which the utterance sounds native is …

The research completed at NIST was done using a technique known as X-ray Mapping. The X-ray techniques were employed to determine the exact nature of the damage caused by CMA. The thesis is a combination of two papers, on the physical effects of CMA and …

Process Modelling Support For The Conceptual Modelling Phase Of A Simulation Project, Cathal Heavey, John Ryan

Conference papers

While many developments have taken place around supporting the model coding task of simulation, there are few tools available to assist in the conceptual modelling phase. Several authors have reported the advantages of using process modelling tools in the early phases of a simulation project.

This paper provides an overview of process modelling tools in relation to their support for simulation, categorizing the tools into formal method and descriptive methods. A conclusion from this review is that none of the tools available adequately support the requirements gathering phase of simulation. This is not surprising as none of the process modelling …

The Role Of Global Land Use In Determining Greenhouse Gases Mitigation Costs, Thomas Hertel, Huey-Lin Lee, Steven Rose, Brent Sohngen

GTAP Working Papers Archive

This paper develops a CGE model with unique regional land types and detailed non-CO2 GHG emissions which it uses to analyze the potential for reductions in land-based greenhouse gas emissions as well as forest sequestration. In our global, general equilibrium analysis of carbon taxation, we find that forest carbon sequestration is the dominant means for global GHG emissions reduction in the land using sectors. However, when compared to the rest of the world, emissions abatement in the US comes disproportionately from agriculture, and, within agriculture, disproportionately from reductions in fertilizer-related emissions (primarily in maize production). In the world as a …

Privilege Through Prayer: Examining Bible-Based Prison Rehabilitation Programs Under The Establishment Clause, Nathaniel J. Odle

ExpressO

In early June of 2006, an Iowa federal judge found a publicly-funded prison ministry to be in violation of the Establishment Clause and ordered it stopped. The program in question, the InnerChange Freedom Initiative, conceived and maintained by Prison Fellowship Ministries, utilized an overtly Christian model to rehabilitate inmates through spiritual and moral regeneration. In the eyes of the court, the failure of the state of Iowa to provide a reasonable secular alternative had the primary effect of advancing religion and fostered excessive governmental entanglement under a traditional Lemon analysis. Equally important in the court’s decision was the lack of …

Void Agreements, Knocked-Out Terms, And Blue Pencils: Judicial And Legislative Handling Of Unreasonable Terms In Noncompete Agreements, Kenneth R. Swift

ExpressO

This article adresses the divergent approaches currently taken by courts after finding an unreasonable term in an employer-employee noncompete agreement. The article begins by reviewing basic standards used to determine if the terms of a noncompete agreement are reasonable. The article then addresses and analyzes the three approaches used by courts after finding an unreasonable term: finding the agreement void in its entirety, using the "Blue Pencil" doctrine to eliminate unreasonable terms and enforce the remaining terms, and using the court's equitable powers to not only remove unreasonable terms, but to rewrite those terms to make them reasonable. The article …

Tightening The Bounds On Feasible Preemption Points, Harini Ramaprasad

Conference Proceedings

Caches have become invaluable for higher-end architectures to hide, in part, the increasing gap between processor speed and memory access times. While the effect of caches on timing predictability of single real-time tasks has been the focus of much research, bounding the overhead of cache warm-ups after preemptions remains a challenging problem, particularly for data caches. This paper makes multiple contributions. 1) We bound the penalty of cache interference for real-time tasks by providing accurate predictions of data cache behavior across preemptions, including instruction cache and pipeline effects. We show that, when considering cache preemption, the critical instant does not …
