Rapid And Accurate C-V Measurements, Ji-Hong Kim, Pragya R. Shrestha, Jason P. Campbell, Jason T. Ryan, David Nminibapiel, Joseph J. Kopanski

Electrical & Computer Engineering Faculty Publications

We report a new technique for the rapid measurement of full capacitance-voltage (C-V) characteristic curves. The displacement current from a 100-MHz applied sine wave, which swings from accumulation to strong inversion, is digitized directly using an oscilloscope from the MOS capacitor under test. A C-V curve can be constructed directly from this data but is severely distorted due to nonideal behavior of real measurement systems. The key advance of this paper is to extract the system response function using the same measurement setup and a known MOS capacitor. The system response correction to the measured C-V curve of the unknown …

Seebeck Coefficient Enhancement Of Ald Pbte/Pbse Nanolaminate Structures Deposited Inside Porous Silicon Templates, Xin Chen, Pengtao Lin, Kai Zhang, Helmut Baumgart, Brian Geist, Vladimir Kochergin

Electrical & Computer Engineering Faculty Publications

In this paper, lead chalcogenide based thermoelectric nanolaminate structures were fabricated by alternately depositing PbTe and PbSe ALD layers on regular planar silicon wafers and on microporous silicon templates. Lead bis(2,2,6,6-tetramethyl-3,5-heptanedionato) (Pb(C₁₁H₁₉O₂) ₂), plus (trimethylsilyl) telluride ((Me₃Si)₂Te) and (trimethylsilyl) selenide ((Me₃Si)₂Se) were used as the chemical ALD precursors for lead, tellurium and selenium, respectively. The Seebeck coefficient in horizontal direction (parallel direction to the surface) to the multiple layered PbTe/PbSe nanolaminate structures was measured by an MMR Seebeck system, and benchmarked against the Seebeck coefficient …

Evidence Of The Excitation Of A Ring-Like Gravity Wave In The Mesosphere Over The Andes Lidar Observatory, Fabio Vargas, Gary Swenson,, Alan Liu, Dominique Pautet

Publications

On 23 March 2012, our all-sky imager recorded a concentric, ring-like gravity wave pattern. The wave arose within the area covered by images of both OH and O(1S) nightglow emissions taken at the Andes Lidar Observatory (ALO), Chile (30.3°S, 70.7°W). We have estimated the observed and intrinsic parameters of the event and located the wave source within the lower mesosphere altitude range using a reverse ray tracing method. By the analysis of GOES and LIS satellite images, we have not found evidence of neither convective nor lightning activity nearby ALO, indicating that the source of the ring-like wave …

Project Execution: A Research Agenda To Explore The Phenomenon, James Walter Marion, Tracey Richardson, Matthew Earnhardt

Publications

It is observed in the literature that although project management is considered to be an execution-oriented discipline, the Project Management Body of Knowledge developed by the Project Management Institute provides relatively little detail in the Executing process group compared with other process groups such as the Planning and Monitoring and Controlling process groups. It is further observed that project elements considered essential to the success of the project including project Scope, Cost, Schedule, and Risk are not included within the Executing process group. Likewise, the coverage of project execution in the Project Manager Competency Development Framework authored by the Project …

From Enrollment To Employment: A Dacum Approach To Information Systems And Information Security And Assurance Curriculum Design, Leila Halawi, Wendi M. Kappers, Aaron Glassman

Publications

Issues associated with information security are numerous and diverse. Since the majority of organizational actions rely greatly on information and communication technologies, Information Systems (IS) security is now a main concern for firms, governments, institutes, and society as a whole. As a result, a plethora of graduate programs have been created, covering nearly every aspect of IS security. The authors review the current state of the IS industry presented in the literature, and identify a panel of IS experts in which to explore current job skill needs using a “Developing a Curriculum,” DACUM, process to support curriculum design for two …

Students' Perception Of The Flipped Classroom In Graphical Communications, Lulu Sun

Publications

The flipped classroom requires students to study concepts before the class, apply what they learn in the classroom, and work with other students, which then makes it possible to get immediate feedback from the instructor. However, the student’s perception of the flipped classroom is not widely investigated in the area of engineering graphics. This paper presents a study of the flipped classroom in a Graphical Communications course. Students are required to study course material online before the face-to-face classroom experience. The online course study includes multimedia materials and an online quiz that they are required to take. The results of …

The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder

Theses and Dissertations

The aim of this study was to compare the incidence of root canal dentinal micro-cracks after canal instrumentation using reciprocating files (WaveOne Gold® and Twisted Adaptive®) and continuous rotation files (Edge Evolve® and EndoSequence®) in an ex-vivo benchtop study. This project used a novel methodology of finding dentinal defects using the “K-cube”, which allows evaluators to visualize sectioned root surfaces before instrumentation and after instrumentation. Mesial roots from 40 human mandibular first molars were divided into 4 groups of 10 for each file type. Root section pictures were taken with a Zeiss Discovery V20 stereomicroscope before and after canal instrumentation. …

Chemometric Curve Resolution For Quantitative Liquid Chromatographic Analysis, Daniel W. Cook

Theses and Dissertations

In chemical analyses, it is crucial to distinguish between chemical species. This is often accomplished via chromatographic separations. These separations are often pushed to their limits in terms of the number of analytes that can be sufficiently resolved from one another, particularly when a quantitative analysis of these compounds is needed. Very often, complicated methods or new technology is required to provide adequate separation of samples arising from a variety of fields such as metabolomics, environmental science, food analysis, etc.

An often overlooked means for improving analysis is the use of chemometric data analysis techniques. Particularly, the use of chemometric …

The Consequences Of Alcohol Mixed With Energy Drink (Amed) Use In College Students With Attention-Deficit/Hyperactivity Disorder (Adhd), Brooke A. Green

Theses and Dissertations

College students with ADHD, but especially those who consume alcohol, may be at jeopardy for experiencing negative educational and occupational outcomes, problematic substance use, criminal offending, and sexual victimization. Alcohol mixed with energy drink (AmED) use is widespread across college campuses and associated with many of these same problematic outcomes. The risk of experiencing these consequences for college students with ADHD may be exacerbated by AmED use given its unique relationship, above and beyond alcohol use, with these variables. This study sought to examine relationships among GPA, lost work performance, hazardous alcohol use, illicit substance use, criminal offending, and sexual …

Evaluation Of Redox Potential As A Novel Biomarker Of Oxidative Stress, Inflammatory Response, And Shock Using Nanoporous Gold Electrodes, Matthew C. Ellenberg

Theses and Dissertations

EVALUATION OF REDOX POTENTIAL AS A NOVEL BIOMARKER OF OXIDATIVE STRESS, INFLAMMATORY RESPONSE, AND SHOCK USING NANOPOROUS GOLD ELECTRODES

Background: Redox potential is a chemical species’ affinity for electrons. Increased oxidant concentration is associated with disease1,2, yet there is not a way to measure systemic redox status.3 Redox potentiometry uses metal electrodes that do not work in blood because protein molecules adhere on the metal surface, blocking electron exchange.

Methods: Nanoporous gold electrodes have large surface areas that allowed electron exchange to continue in blood.4 Redox potential was measured in blood with ascorbic acid, in cardiac bypass patients and pigs …

From Seed To Sky: Impacts Of Explosive Compounds On Vegetation Across Spatial And Developmental Scales, Stephen M. Via

Theses and Dissertations

Explosive compounds are broadly distributed across the globe as a result of nearly two centuries of munitions use in warfare and military activities. Two explosive compounds have seen disproportionate use; RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) and TNT (2-methyl- 1,3,5-trinitrobenzene), being the most commonly found explosives in the environment. The effects of explosives on biota have been studied in great detail; however, there is a general lack of understanding with regard to broader ecological impacts of these contaminants. My dissertation objective was to follow the impacts of explosive compounds on vegetation across scales. Impacts on vegetation at the species scale alter community composition via …

Identifying Parameters For Robust Network Growth Using Attachment Kernels: A Case Study On Directed And Undirected Networks, Ahmed F. Abdelzaher

Theses and Dissertations

Network growing mechanisms are used to construct random networks that have structural behaviors similar to existing networks such as genetic networks, in efforts of understanding the evolution of complex topologies. Popular mechanisms, such as preferential attachment, are capable of preserving network features such as the degree distribution. However, little is known about such randomly grown structures regarding robustness to disturbances (e.g., edge deletions). Moreover, preferential attachment does not target optimizing the network's functionality, such as information flow. Here, we consider a network to be optimal if it's natural functionality is relatively high in addition to possessing some degree of robustness …

The Painful Long Head Of The Biceps Brachii: Nonoperative Treatment Approaches, Kevin E. Wilk, Todd R. Hooks

Physical Therapy Faculty Research and Publications

Pain associated with the long head of the biceps (LHB) brachii seems to be increasingly recognized in the past 4 to 5 years. The LHB has long been considered a troublesome pain generator in the shoulder. Abnormality involving the LHB brachii has long been an area of debate, with Codman in 1934 even questioning the specificity of the diagnosis of biceps tendinitis. Biceps tendon abnormality is often associated with rotator cuff impingement. Shoulder pain originating from the biceps tendon can be debilitating, causing a severe decrease in shoulder function. As a result of the frequent clinical presentation of biceps pain, …

From Patient Rights To Health Justice, Lindsay Wiley

Scholarly Articles in Law Reviews & Journals

Models emphasizing professional autonomy, patient rights, market power, and health consumerism are no longer adequate to address the increasingly social, collective nature of health law institutions, instruments, and norms. What is needed is a new model that expressly recognizes the public-alongside the patient, the provider, and the payer-as an important stakeholder and active participant in decisions about medical treatment, health care coverage, and allocation of scarce resources. In a previous article, the author looked to the environmental justice, reproductive justice, and food justice movements for inspiration in developing a "health justice" approach to eliminating social disparities in health. This Article …

Layers, Michelle J. Mcgrath

Theses and Dissertations

In my paintings and mixed media works, I incorporate rough textures and vibrant, high contrast colors. I find beauty and intrigue in the gnarled roots of a tree; the crumbling plaster on a wall; and the wrinkled, roughened hands of my grandmother. To explore these types of surfaces, the materials are distorted by twisting, ripping, and pulling the pieces apart. For instance, canvas is layered and stitched together in an uneven manner with knots and lumps added to the distressed surface. I view these distorted, strained surfaces as different forces in my life that push or pull me in varied …

Shifting Focus, Dawn R. Gillis

Theses and Dissertations

My photographic and craft works focus on the flowing forms of flowers; the delicate, ruffled edges of feathers; and the complex veining patterns of leaves. To highlight these natural elements I use a limited palette, often no more than two close value colors. My photographs are extreme close-ups and are referred to as macrophotography. The images are abstracted yet still hint at the organic original. In my crafts, which include jewelry, textiles, and books, I also use a reduced palette when presenting abstracted natural structures.

I use a process-oriented approach to allow for repetitive tasks. The repetition is rewarding in …

From Intra- To Inter-Personal: Effects Of Mindfulness Training On Emotion Regulation In Social Contexts, Jordan T. Quaglia

Theses and Dissertations

The social and emotional lives of people are highly interdependent. Incipient evidence suggests that attention may also play an essential role in determining one’s social and emotional well-being. Mindfulness, as a manner of attending, entails greater moment-to-moment awareness to internal and external events, and is thought to have both intra- and inter-personal benefits. Here a study of mindfulness training (MT) examined whether training mindful attention would improve emotion regulation in social contexts as indexed by neural, behavioral, and experience sampling measures. More specifically, 60 participants in romantic relationships were randomly assigned to either four brief (20 min.) MT sessions or …

In Vitro Visualization Of Pediatric Sized Mechanical Heart Valve Performance Using Aortic Root Model In Mock Circulatory Loop, Sarah Lederer

Theses and Dissertations

Congenital heart valve disease is one of the most common abnormalities in children, with common valve defects being aortic stenosis, mitral stenosis, and valvular regurgitation. Although adult sized mechanical heart valve (MHV) replacements are widely studied and utilized, there are currently no FDA approved prosthetic heart valves available for the pediatric population. This is due to a variety of reasons such as a limited patient pool for clinical trials, limited valve sizes, and complex health histories in children. Much like adult sized mechanical heart valves, potential complications with pediatric heart valve replacements include thrombosis, blood damage due to high shear …

Perception Of Profile Appearance As Judged By Peers Using 3d Video Imaging, Megan G. Schuler

Theses and Dissertations

The purpose of this study was to investigate the social perceptions of subjects with differing lip position and facial convexity in three dimensions. A 3dMD camera (3dMD, Atlanta, GA) was used to capture 3D images of 9 subjects’ faces. The images were altered to have ideal lip position and ideal convexity, ideal lip position and Class II convexity, Class II lip position and ideal convexity, and Class II lip position and Class II convexity. 400 laypersons rated their perceptions of the subjects’ athletic ability, popularity, leadership, and intelligence on a VAS scale. Subjects with ideal lip position relative to the …

Design & Analysis Of A Computer Experiment For An Aerospace Conformance Simulation Study, Ryan W. Gryder

Theses and Dissertations

Within NASA's Air Traffic Management Technology Demonstration # 1 (ATD-1), Interval Management (IM) is a flight deck tool that enables pilots to achieve or maintain a precise in-trail spacing behind a target aircraft. Previous research has shown that violations of aircraft spacing requirements can occur between an IM aircraft and its surrounding non-IM aircraft when it is following a target on a separate route. This research focused on the experimental design and analysis of a deterministic computer simulation which models our airspace configuration of interest. Using an original space-filling design and Gaussian process modeling, we found that aircraft delay assignments …

Narrative And The Reconfiguration Of The Humanist Subject In Robbe-Grillet, Ballard, And Ligotti, Zachary L. Acosta-Lewis

Theses and Dissertations

This thesis examines the utility of the novels, short stories, critical writing, and generically indistinct work of Alain Robbe-Grillet, J.G. Ballard, and Thomas Ligotti in developing a critique of the contemporary manifestations of liberal humanist social, economic, and political subjectivities. To this end, the concurrence of formal fragmentation and sublime aesthetics in early Gothic fiction models the manner in which narrative structures can appropriate structural tropes of dominant institutions, critically reflecting ideological fracture. Read according to the assemblative approach outlined by Deleuze and Guattari, these authors serve as a productive and incisive response to the hegemony of capitalist territorialization with …

Identifying As Author: Exploring The Pedagogical Basis For Assisting Diverse Students To Discover Their Identities Through Creatively Defined Literacy Narratives, Amber D. Pullen

EWU Masters Thesis Collection

This thesis explores the current discourse surrounding the redefinition of concepts such as text and authorship in the field of composition studies. Drawing from scholarship on topics ranging from multi-modal composition to feminist historical-appropriation, the author builds a case for redefining these concepts to include a broader range of texts and author-voices from which instructors can draw for course readings. By focusing on the particular instance of selecting readings to teach a literacy narrative unit in a first year college composition course, the author shows how redefining and broadening concepts of text and authorship may allow for students to more …

Near Real-Time Early Cancer Detection Using A Graphics Processing Unit, Jason Helms

EWU Masters Thesis Collection

"Automatically detecting early cancer using medical images is challenging, yet very crucial to help save millions of lives in the early stages of cancer. In this work, we improved a method that was originally developed by Yamaguchi et al. from the Saga University in Saga Japan. The original method would first decompose the endoscopic image into four color elements: red, green, blue and luminance (RGBL). Next each component is again decomposed to non-overlapping blocks of smaller images. Each smaller image undergoes two phases of DWT(s) and finally the Fractal Dimension (FD) is calculated per smaller image and abnormal regions are …
