Contingency Constrained Economic Dispatch In Smart Grids With Correlated Demands, Yiyu Shi, Jinjun Xiong

Electrical and Computer Engineering Faculty Research & Creative Works

Contingency constrained economic dispatch has been an extensively studied research topic. However, most existing works assume that the load demands at all buses are given. Such an assumption works well for conventional power grids, where the load demands are relatively easy to predict. We can select a few representative demand profiles and perform economic dispatch over them. However, such a practice will no longer work in smart grids, where the load demands fluctuate dramatically. We will need a huge number of demand profiles to cover all possible scenarios, which is computationally expensive. to address the problem, we propose a parameterized …

Soft-Decision Feedback Turbo Equalization For Multilevel Modulations, Huang Lou, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

Error propagation phenomena is the major drawback for existing hard-decision feedback turbo equalizers. in this paper, we propose a new soft-decision feedback equalizer (SDFE) suitable for multilevel modulation systems employing turbo equalization. the proposed SDFE offers a low computational complexity growing only linearly with the number of equalizer coefficients, as opposed to the quadratic complexity of MMSE-Based linear turbo equalizer with time-varying coefficients (Exact-MMSE-LE). the performance and convergence property of the proposed SDFE are analyzed using extrinsic information transfer (EXIT) chart and verified by simulations in a severe InterSymbol interference channel set by Proakis. Results show that our approach performs …

3d Image Reconstruction From Sparse Measurement Of Wideband Millimeter Wave Sar Experiments, Hamed Kajbaf, Joseph T. Case, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

Nonuniform random sampling is applied to a wideband 3D synthetic aperture radar (SAR) imaging system to reduce the number of measurement points in both frequency and space domains. Experimental tests were performed on a construction foam specimen using uniformly sampled Q-band frequencies in 35.04 GHz to 44.96 GHz and at a grid of two-millimeter step sizes. using discrete Fourier transform (DFT) or discrete cosine transform (DCT) sparse representations, the 3D images can be reconstructed from 7% random samples of the experimental data achieving comparable quality as the one from original full-set data. This can translate to significant time reduction of …

Mahalanobis-Taguchi System As A Multi-Sensor Based Decision Making Prognostics Tool For Centrifugal Pump Failures, Ahmet Soylemezoglu, Sarangapani Jagannathan, Can Saygin

Electrical and Computer Engineering Faculty Research & Creative Works

A novel Mahalanobis Taguchi System (MTS) based fault detection, isolation, and prognostics scheme is presented. the proposed scheme fuses data from multiple sensors into a single system level performance metric using Mahalanobis Distance (MD) and generates fault clusters based on MD values. MD thresholds derived from the clustering analysis are used for fault detection and isolation. When a fault is detected, the prognostics scheme, which monitors the progression of the MD values over time, is initiated. Then, using a linear approximation, time to failure is estimated. the performance of the scheme has been validated via experiments performed on a mono-block …

Electrical and Computer Engineering Faculty Research & Creative Works

Computer programming education helps to prepare pre-college students to function in a technology-based society and to promote technical careers. However, opportunities are limited for pre-college students to learn computer programming and effective programming instruction can be difficult. A set of introductory, self-paced tutorials in Squeak Smalltalk has been developed for students in high school and middle school. This work describes two supplementary exercises that address the needs of new learners, especially those at younger ages. Students are given tools for drawing and image manipulation. The optional exercises integrate basic concepts while allowing more interactivity and customization through creative "play." © …

Sufficient Conditions For Uniqueness Of The Weak Value, Justin Dressel, Andrew N. Jordan

Mathematics, Physics, and Computer Science Faculty Articles and Research

We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned average using the contextual values formalism introduced in Dressel, Agarwal and Jordan (2010 Phys. Rev. Lett. 104 240401). We also respond to criticism of our work by Parrott (arXiv:1105.4188v1) concerning a proposed counter-example to the uniqueness of the definition of the generalized weak value. The counter-example does not satisfy our prescription in the case of an underspecified measurement context. We show that when the contextual values formalism is properly applied to this example, a natural interpretation of the …

Intraoperative Pain Management: Attenuating Postoperative Pain In Pediatric Patients, Alicia M. Wolfgram

Theses and Dissertations

More than 5 million children undergo surgery in the United States each year, and it is estimated that up to 75% (3.75 million) of them experience significant postoperative pain (Fortier, MacLaren, Martink, Perret-Karimi, & Kain, 2009). While we have come a long way in our knowledge of pain in children, it is often found that pain is inadequately assessed and treated. Aside from the cost associated with increased utilization of medical visits, psychological implications (anxiety, avoidance, sleep disturbances), and increased parental distress related to pediatric pain, there are many physiologic changes associated with pain that may delay or prevent wound …

"The Course Fit Us": Differentiated Instruction In The College Classroom, Mary Volesky Dosch

Theses and Dissertations

Differentiated instruction is a learner-centered philosophy of teaching based on Tomlinson’s research, but stems from a constructivist belief espoused by Dewey, Piaget, and Vygotsky. Through consideration of three diagnostic areas: readiness, interests, and learning profiles, a teacher differentiates how diverse students access the material (content), how students make sense of the material (process), and how students demonstrate their learning (product).

Differentiated instruction has been used successfully at the elementary, middle, and high school levels showing quantitative improvements for diverse students. A limited number of qualitative studies on differentiated instruction exist at the college level, with even fewer quantitative studies.

Implications Of Fatigue And Sleep Loss On Medical Professionals And Countermeasures To Prevent Fatigue, Tracie J. Christensen

Theses and Dissertations

The number of hours worked per individual has long been limited by the law in many professional industries. Recent increases in the incidence of medical and diagnostic errors related to fatigue has led to an increased interest in health care worker fatigue. For human beings, functioning on a 24-hour basis poses unique physiological challenges. Acknowledging and managing these challenges can promote performance, productivity, and safety in 24-hour operations. Ignoring these factors can lead to decrements in human capability and to the potential for incidents and accidents that can result in tremendous societal and individual costs. Long duty hours, reduced sleep …

Lumbar Facet Joint Pain: Pathology And Treatment Via Facet Joint Injection And Medial Branch Neurology, Andrew L. Schott

Theses and Dissertations

Clinic spinal pain or "back pain" as it is sometimes referred is a serious medical problem with se1ious financial and social consequences (Manchikanti, 1999). Back and neck pain are the most common cause of chronic pain and disability (Raso, 2010). Certified Registered Nurse Anesthetists are advanced practitioners with the ability to treat lower back pain using advanced interventional procedures; however, they currently are not pardoning these interventions in North Dakota. A comprehensive literature review was utilized to gather current data and group trends in the treatment of lumbar facet joint pain. History and physicals, while helpful, do not accurately diagnose …

Treatment Of Opiate Abuse: Increasing Patient Self-Efficacy And Engagement In Treatment Through Education Of Providers, Kimberly Wight

Theses and Dissertations

Opiate abuse is one of the fastest growing public health concerns in the United States and has far reaching ramifications that effect individual patients and their families, communities, and the healthcare system (U.S. Department of Justice National Drug Intelligence Center, 2010). It has been shown that there is significant gap in knowledge among healthcare providers surrounding the topic of opiate abuse and dependence as well as the available pharmacologic treatments that are available to help relieve withdrawal as well as help maintain heal truer lifestyles. In addition to this lack in knowledge there appears to be a gap in recognizing …

The Role Of The School Nurse In Advocating For Comprehensive Sex Education In Schools, Heather Weaver

Theses and Dissertations

Despite recent decreases in teen pregnancy rates, teen pregnancy remains a significant public health problem. In the past two decades, funding has been available supporting sex education; however, many of these programs have not been effective in reducing teen pregnancy rates. Research supports the use of comprehensive sex education as effective tools in delaying sexual initiation and preventing teen pregnancy. School nurses are essential in the advocacy of policy change at the federal, state, and local levels. School nurses serve in leadership roles for health policies and programs. This article aims at describing research based advocacy programs that may assist …

Investigation Of A Novel Method For Polonium-210 Determination In Groundwater, Tara Matheny

All Theses

A novel method was investigated for the quantification of 210Po in water as an alternative to the standard method of spontaneous plating onto Ag disks followed by quantification with an alpha spectrometer. The novel method concentrated a 0.5L sample by MnO2 co-precipitation followed by dissolution of the precipitate into a solution. Polonium-210 was separated from the solution and quantified in a column containing a 50:50 by volume mixture of Pb resin (Eichrom Technologies, Inc.) mixed with granulated CaF2:Eu scintillator. The column containing 210Po is quantified on a liquid scintillation counter without the introduction of liquid cocktail. The minimum detectable concentration …

Fabrication Of All-Inorganic Nanocrystal Solids Through Matrix Encapsulation Of Nanocrystal Arrays, Erich Kinder, Pavel Moroz, Geoffrey Diederich, Alexa Johnson, Maria Kirsanova, Alexander Nemchinov, Timothy O’Connor, Dan Roth, Mikhail Zamkov

Physics and Astronomy Faculty Publications

A general strategy for low-temperature processing of colloidal nanocrystals into all-inorganic films is reported. The present methodology goes beyond the traditional ligand-interlinking scheme and relies on encapsulation of morphologically defined nanocrystal arrays into a matrix of a wide-band gap semiconductor, which preserves optoelectronic properties of individual nanoparticles while rendering the nanocrystal film photoconductive. Fabricated solids exhibit excellent thermal stability, which is attributed to the heteroepitaxial structure of nanocrystal matrix interfaces, and show compelling light-harvesting performance in prototype solar cells.

Local Television Coverage Of A Mall Shooting: Separating Facts From Fiction In Breaking News, Jeremy Harris Lipschultz, Michael L. Hilt

Communication Faculty Publications

Local TV news emphasizes the earliest stage of crimes because ‘‘breaking news’’ is fresh, dramatic and visual. A qualitative analysis was conducted using a comprehensive set of recordings of the first three-and-a-half hours of local television news coverage in Omaha, Nebraska. This study identified a series of ongoing issues that have important implications for newsroom decision-makers. Local television news used charged and dramatic language, such as that shooting victims were ‘‘fighting for their lives.’’ Reporters and news managers find themselves in the middle of a struggle between two options: remaining a distant and objective observer of events, or connecting with …

Brief Assessment Of Schizotypy: Developing Short Forms Of The Wisconsin Schizotypy Scales, Beate P. Winterstein, Paul J. Silvia, Thomas R. Kwapil, James C. Kaufman, Roni Reiter-Palmon, Benjamin Wigert

Psychology Faculty Publications

The Wisconsin Schizotypy Scales—the Perceptual Aberration, Magical Ideation, Physical Anhedonia, and Revised Social Anhedonia Scales—have been used extensively since their development in the 1970s and 1980s. Based on psychometric analyses using item response theory, the present work presents 15-item short forms of each scale. In addition to being briefer, the short forms omit items with high differential item functioning. Based on data from a sample of young adults (n = 1144), the short forms have strong internal consistency, and they mirror effects found for the longer scales. They thus appear to be a good option for researchers interested in …

Extrapolating Strategies For The Scientific And Technological Development Of Underdeveloped Societies From The Examples Of South Korea, Slovenia And Serbia, Vuk Uskoković, Dragan Uskoković

Pharmacy Faculty Articles and Research

The recent history of scientific excellence of a society could be used as an indicator of its economic, cultural and communal prosperity. In this work, two examples of countries that successfully arose from the remnants of comparative poverty and established themselves as scientifically thriving societies, South Korea and Slovenia, are compared with the case of Serbia, a country that is presumably on the doorsteps of a similarly explosive developmental path. Guidelines for social progress in the direction of greater scientific and social prominence are outlined in the course of the discourse. It is concluded that the ideal model of growth …
