Neutrosophic Principle Of Interconvertibility Matter-Energy Information, Florentin Smarandache, Stefan Vladutescu

Branch Mathematics and Statistics Faculty and Staff Publications

The research aims to reveal and prove the thesis of the neutral and convertibility relationship between constituent constructive elements of the universe: matter, energy and information. The approach perspective is a computationally-communicative neutrosophic one. We configure a coherent and cohesive ideation line. Matter, energy and information are fundamental elements of the world. Among them, there is an inextricable multiple, elastic and evolutionary connection. The elements are defined by the connections between them. Our hypothesis is that the relationship between matter, energy and information is a neutral one. This relationship is not required by the evidence. At this level, it does …

Impact Of Intelligent Transportation Systems On Parallel Hybrid Electric Heavy Duty Vehicles, Ahmed Shihab Ahmed Al-Samari

Graduate Theses, Dissertations, and Problem Reports (ETD)

A hybrid electric vehicle uses multiple sources of energy that can be independently or all together used to propel the wheels. In the presented work, the vehicle propulsion controller (VPC) for a parallel heavy duty hybrid electric vehicle (HEV) model has been modified to manage the alternative power source in advance based on the forthcoming traffic information. The goal is to prepare the powertrain for the next power event by making more energy storage capacity to capture free energy via regenerative braking or store more energy for expected need. The method of preparation will be by managing the battery state …

Energy-Efficient Wireless Interconnect Design For Non-Destructive Testing (Ndt) Applications, Lokesh Avala

Graduate Theses, Dissertations, and Problem Reports (ETD)

A method for non-destructive, wireless testing of integrated circuits(ICs) is presented in this thesis. This system is suitable for applications which require testing after the manufacturing of ICs. According to Moore's Law the number of transistors in an IC doubles every two years, the current probing equipment will also have to reduce its size accordingly which will be difficult after a certain point. The proposed system relies on near field communication in order to transfer data between probe and device under test. The probe and IC will include small antenna and a transceiver circuit. The antenna and the transceiver circuit …

Statistical Methods For Detection And Mitigation Of The Effect Of Different Types Of Cyber-Attacks And Inconsistencies In Electrical Design Parameters In A Real World Distribution System, Vivek Joshi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the present grid real time control systems are the energy management systems and distribution management systems that utilize measurements from real-time units (RTUs) and Supervisory Control and Data Acquisition (SCADA). The SCADA systems are designed to operate on isolated, private networks without even basic security features which are now being migrated to modern IP-based communications providing near real time information from measuring and controlling units. To function "brain" (SCADA) properly "heart" (RTUs) should provide necessary response thereby creating a coupling which makes SCADA systems as targets for cyber-attacks to cripple either part of the electric transmission grid or fully …

Introduction To Animal- And Nature-Assisted Therapies: A Service-Learning Model For Rural Social Work, Laura J. Praglin, Linda L. Nebbe

Contemporary Rural Social Work Journal

This teaching note details the teaching philosophy and practices of an innovative university service-learning course in nature- and animal-assisted therapies. The course took place at a wildlife rehabilitation center, and students engaged as counselors, putting academic theories into action by facilitating an “animal camp” for 25 at-risk children. The course represented a “best practice” in rural social work given its intensive focus upon social work’s ecological and person-in-environment perspectives; multidisciplinary, collaborative community-based partnerships; and evocation of a rural schoolhouse model.

Performance Of Reformed Low-Sulfur Liquid Fuels In A Solid Oxide Fuel Cell, Tristan Jordan Mcquain

Graduate Theses, Dissertations, and Problem Reports (ETD)

A solid oxide fuel cell (SOFC) is a device capable of converting chemical energy from gaseous fuels into useable electrical energy at high efficiencies. Since the United States transportation sector infrastructure is currently based on liquid fuels, this opens up a large market for alternative power units utilizing SOFC technology for liquid fuels. In this work, a novel rhodium and strontium-substituted lanthanum zirconate pyrochlore (LSRZ) catalyst developed by the U.S. Department of Energy's National Energy Technology Laboratory (NETL) was utilized in a reforming reactor to convert low-sulfur liquid hydrocarbon fuels to syngas for direct use in a SOFC. The SOFC …

Synchronization Behavior In Coupled Chemical Oscillators, Simbarashe Nkomo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Synchronization is a collective phenomenon emerging from the interactions of different dynamical systems. Systems with different characteristics adjust their behavior to a common behavior of the group. This collective behavior is observed in many biological, chemical, and physical systems. Examples from different fields include pacemaker heart cells, synchronization of neurons during epilepsy seizures, arrays of microwave oscillators, and robot manipulators. Studies of coupled oscillators have revealed different mechanisms by which discrete oscillators interact and organize to a uniform synchronized state from an incoherent state. The discovery of a new type of synchronization state, called the chimera state has further broadened …

Monitoring The Integrity Of Co2 Storage Sites Using Smart Field Technology, Seyed Alireza Haghighat

Graduate Theses, Dissertations, and Problem Reports (ETD)

Capability of underground carbon dioxide storage to confine and sustain injected CO2 for a very long time is the main concern for geologic CO2 sequestration. If a leakage from a geological sink occurs, it is crucial to find the approximate amount and location of the leak in order to implement proper remediation activity.;An overwhelming majority of research and development for storage site monitoring has been concentrated on atmospheric, surface or near surface monitoring of the sequestered CO2. This study is different it aims to monitor the integrity of CO2 storage at the reservoir level. This work proposes developing in-situ CO2 …

Cross Trees: Visualizing Estimations Using Decision Trees, Naveen Kumar Lekkalapudi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Optimization has been the goal of almost every human thought and action. With the growing computational capabilities, solutions to problems are also exponentially increasing. With rising demand for data and analytics on this big data, solutions to problems are also multiplied. Although, strong statistical and analytical reasoning has helped narrow down many solutions into set of feasible applicable solutions; Experts also seek knowledge of how these solutions have improved and what decisions are needed to be taken for remaining solutions to improve. This problem persists in software engineering with managers and domain experts taking decisions deciding future course of the …

Analyses Of Crime Patterns In Nibrs Data Based On A Novel Graph Theory Clustering Method: Virginia As A Case Study, Peixin Zhao, Majorie Darrah, Jim Nolan, Cun-Quan Zhang

Faculty & Staff Scholarship

This paper suggests a novel clustering method for analyzing the National Incident-Based Reporting System (NIBRS) data, which include the determination of correlation of different crime types, the development of a likelihood index for crimes to occur in a jurisdiction, and the clustering of jurisdictions based on crime type. The method was tested by using the 2005 assault data from 121 jurisdictions in Virginia as a test case. The analyses of these data show that some different crime types are correlated and some different crime parameters are correlated with different crime types. The analyses also show that certain jurisdictions within Virginia …

* The Use Of Tree Crown Variables In Over-Bark Diameter And Volume Prediction Models, Ramazan Ozcelik, Maria J. Diamantopoulou, John R. Brooks

Faculty & Staff Scholarship

Linear and nonlinear crown variable functions for 173 Brutian pine (Pinus brutia Ten.) trees were incorporated into a well-known compatible volume and taper equation to evaluate their effect in model prediction accuracy. In addition, the same crown variables were also incorporated into three neural network (NN) types (Back-Propagation, Levenberg-Marquardt and Generalized Regression Neural Networks) to investigate their applicability in over-bark diameter and stem volume predictions. The inclusion of crown ratio and crown ratio with crown length variables resulted in a significant reduction of model sum of squared error, for all models. The incorporation of the crown variables to these …

A Decision Framework For Optimal Pairing Of Wind And Demand Response Resources, C. Lindsay Anderson, Judith Cardell

Engineering: Faculty Publications

Day-ahead electricity markets do not readily accommodate power from intermittent resources such as wind because of the scheduling difficulties presented by the uncertainty and variability in these resources. Numerous entities have developed methods to improve wind forecasting and thereby reduce the uncertainty in a day-ahead schedule for wind power generation. This paper introduces a decision framework for addressing the inevitable remaining variability resulting from imperfect forecasts. The framework uses a paired resource, such as demand response, gas turbine, or storage, to mitigate the generation scheduling errors due to wind forecast error. The methodology determines the cost-effective percentage, or adjustment factor, …

Intrasubject Variability In Power Reflectance, Defne Abur, Susan E. Voss, Nicholas J. Horton

Engineering: Faculty Publications

Background: Power reflectance measurements are an active area of research related to the development of noninvasive middle-ear assessment methods. There are limited data related to test-retest measures of power reflectance.

Purpose: This study investigates test-retest features of power reflectance, including comparisons of intrasubject versus intersubject variability and how ear-canal measurement location affects measurements.

Research Design: Repeated measurements of power reflectance were made at about weekly intervals. The subjects returned for four to eight sessions. Measurements were made at three ear-canal locations: a deep insertion depth (with a foam plug flush at the entrance to the ear canal) and both …

Understanding The Times: A Causal/Comparative Study Of The Effectiveness Of A Christian Worldview Curriculum In Helping Students Develop A Christian Worldview, Donald Barrows

Doctoral Dissertations and Projects

Christian educators are concerned about the development of a Christian worldview in their students. They also desire that their students maintain that worldview after graduation. In this study, the author attempts to determine the effectiveness of the Understanding the Times Christian worldview curriculum in helping students develop a Christian worldview. To do this, a causal/comparative research design was used as participants took a worldview test to determine the extent to which their worldviews compared with biblical teachings. The researcher sampled a random sample of Christian high school graduates who have taken the yearlong Understanding the Times Christian worldview course at …

Separated Response Function Ratios In Exclusive, Forward Π± Electroproduction, G. M. Huber, H. P. Blok, C. Butuceanu, D. Gaskell, T. Horn, D. J. Mack, D. Abbott, A. Klein, L. M. Qin, K. Vansyoc

Physics Faculty Publications

The study of exclusive π^± electroproduction on the nucleon, including separation of the various structure functions, is of interest for a number of reasons. The ratio R-L=sigma(pi-)(L) / sigma(pi+)(L) is sensitive to isoscalar contamination to the dominant isovector pion exchange amplitude, which is the basis for the determination of the charged pion form factor from electroproduction data. A change in the value of R-T=sigma(pi-)(L) / sigma(pi+)(L) from unity at small -t, to 1/4 at large -t, would suggest a transition from coupling to a (virtual) pion to coupling to individual quarks. Furthermore, the mentioned ratios may show an earlier …

A Study Of Personal Cloud Computing: Compatibility, Social Influence, And Moderating Role Of Perceived Familiarity, Murad Moqbel, Valerie L. Bartelt, Mohammed Al-Suqri

Information Systems Faculty Publications

Building on a research framework based on the Theory of Reasoned Action (TRA), Innovation Diffusion Technology (IDT), and the Technology Adoption Model (TAM), we propose a model integrating compatibility, social influence, and perceived familiarity given the implicit uncertainty of personal cloud. Our model emphasizes the moderating effect of perceived familiarity on the relationships between both perceived compatibility and social influence on behavioral intention. PLS-based structural equation modeling is employed to test the related propositions empirically. Results from a survey, involving 265 university students, reveal that perceived compatibility explains a larger proportion of the variance in behavioral intention; perceived familiarity plays …

Smooth Peano Functions For Perfect Subsets Of The Real Line, Krzysztof Ciesielski

Faculty & Staff Scholarship

In this paper we investigate for which closed subsets P of the real line R there exists a continuous map from P onto P 2 and, if such a function exists, how smooth can it be. We show that there exists an infinitely many times differentiable function f : R → R 2 which maps an unbounded perfect set P onto P 2 . At the same time, no continuously differentiable function f : R → R 2 can map a compact perfect set onto its square. Finally, we show that a disconnected compact perfect set P admits a continuous …
