The Progressive Development Of Turbulence Statistics And Its Impact On Wind Power Predictability, Thomas Woolmington, Keith Sunderland, Jonathan Blackledge, Michael Conlon

Articles

Wind resource assessment is a critical parameter in a diverse range of considerations within the built environment. Engineers and scientists, engaging in building design, energy conservation/application and air-quality/air-pollution control measures, need to be cognisant of how the associated wind resource imposes increased complexities in their design and modelling processes. In this regard, the morphological heterogeneities within these environments, present significant challenges to quantifying the resource and its turbulent characteristics.

This paper presents three aspects of turbulence assessment within the built environment. Firstly, an analysis of how turbulence is currently quantified is considered. The industry standard, Turbulent Intensity (TI) is compared …

It will report a novel method for the determination …

"This Masterpiece Of Nature:" An Ecocritical Study Of Joseph Conrad's Fiction, Sonja Luther

Dissertations

This dissertation employs an ecocritical approach to explore the relationship between humans and nature in the works of Joseph Conrad. In his fiction, Conrad draws an impression of nature that was unusual for its time because of its complexity. Nature is not just simple scenery or a stage set in Conrad’s fiction; it plays a major role in his characters’ regression, which develops parallel to their alienation from nature. This dissertation explores the origins of man’s alienation from nature in Conrad’s work, particularly his early fiction, and the implications for society if such alienation continues.

Chapter I serves as an …

Dysphoria And Dysregulation: Exploration Of Affect And Dissociation In The Pain Response To Non-Suicidal Self-Injury, Rita Eileen Todd

Dissertations

Research on non-suicidal self-injury (NSSI) has largely demonstrated increases in pain threshold and pain tolerance in those individuals who have engaged in NSSI, even if they no longer engage in these behaviors (Hooley, Ho, Slater, & Lockshin, 2010). However, little research has been conducted on the mechanisms for these alterations in pain response. Moreover, explorations of these factors often focused on clinical samples despite the growing prevalence of NSSI in adolescents and young adults who are not in treatment. To address these concerns, college students with and without a history of NSSI (N = 69) aged 18 to 53 …

Molecular Probes For The Detection Of Zn2+ And Fe3+ Ions, Erendra Manandhar

Dissertations

A number of molecular probes have been designed and synthesized for the detection of Zn²⁺ and Fe³⁺ ions. Two types of functional groups have been incorporated into the molecular scaffolds to utilize different fluorescent mechanisms. The first class of receptors contains a pyrene moiety. These molecular probes use the excimer mechanism for the detection of Zn²⁺ ion. The probes work well in an organic solvent with a detection limit of 20 nM (one ppb). Alternatives are made to make them water soluble, but this proved to be difficult. An interesting ion-induced self-assembly system will also be discussed. …

Language Use In Mathematics Textbooks Written In English And Spanish, Kailie Ann Bertoch

Theses and Dissertations

Research has suggested that although mathematics is a universal language, the notation, algorithms, and language in which it is taught varies from country to country. The literature has addressed the challenges associated with understanding the language of mathematics in English. Variable is a topic of mathematics where the literature has documented students' difficulty understanding the language of mathematics. Part of that difficulty is attributed to the fact that mathematics and English each have their own register and at times the differences in these registers conflict. This study examined the introduction and use of variable in the middle school textbooks of …

Classifying And Cataloging Cyber-Security Incidents Within Cyber-Physical Systems, William B. Miller

Theses and Dissertations

In the past, there were perceived delineations between the cyber world and the physical world. We are becoming increasingly aware of the overlap between these two worlds, and the overlap itself is increasing. The overlap between these two worlds is known as cyber-physical systems. There have been several incidents involving cyber-physical systems and the number of these incidents is increasing dramatically. In the past there has been no effort to identify methods for describing these incidents in the unique context of cyber-physical systems. This research provides a taxonomy for classifying these incidents that focuses on cross domain, impact oriented analysis. …

Targeted Sequencing Of Plant Genomes , Mark D. Huynh

Theses and Dissertations

Next-generation sequencing (NGS) has revolutionized the field of genetics by providing a means for fast and relatively affordable sequencing. With the advancement of NGS, whole- genome sequencing (WGS) has become more commonplace. However, sequencing an entire genome is still not cost effective or even beneficial in all cases. In studies that do not require a whole-genome survey, WGS yields lower sequencing depth and sequencing of uninformative loci. Targeted sequencing utilizes the speed and low cost of NGS while providing deeper coverage for desired loci. This thesis applies targeted sequencing to the genomes of two different, non-model plants, Artemisia tridentate (sagebrush) …

Extent Of Cysteine Modification Of Snap-25 In Vitro, Alex Mcgregor Dabell

Theses and Dissertations

Exocytosis, the fusion of a vesicle to a cellular membrane, involves a protein named SNAP-25. This protein, containing two alpha helices connected with a linker region, is localized to the cell membrane via palmitic acids attached to the cysteine residues of its linker region in a process called palmitoylation. Are cysteine residues of the SNAP-25 linker region palmitoylated in an ordered manner and to a particular extent? The answer to this question may give insight into the regulated nature of exocytosis. While it is generally accepted that SNAP-25 must be palmitoylated in order to perform its exocytotic functions, the details …

Language Pathways Defined In A Patient With Left Temporal Lobe Damagesecondary To Traumatic Brain Injury: A Qeeg & Mri Study, Janelle Lee Bailey

Theses and Dissertations

Though the current understanding of language processing is incomplete, it has been established that the left hemisphere is dominant for language in the majority of the population. Damage to language centers of the brain and to white matter tracts connecting these language centers results in a language deficit known as aphasia. Neuroplasticity in the brain can often compensate for these language deficits by strengthening neuronal connections between the right and left hemisphere, or by enhancing the neuronal connectivity of undamaged areas in the left hemisphere. Thus the brain can compensate for damaged language centers by using alternative cortical areas. These …

Pmsm Sensorless Speed Control Drive, Youakim Kalaani, Rami J. Haddad, Adel El-Shahat

Electrical & Computer Engineering: Faculty Publications

Permanent magnet synchronous machines (PMSM) are very popular in many industrial applications such as in mechatronics, automotive, energy storage flywheels, centrifugal compressors, vacuum pumps, and robotics. This paper proposes Sensorless control for a PMSM speed drive which is based on a closed loop control system using a proportional and integral (PI) controller that is designed to operate in flux weakening regions under a constant torque angle. This Sensorless element was adopted for best estimating the PMSM rotor position based on its performance characteristics eliminating the need for speed sensors which are usually required in such control applications. To achieve this …

In The Wake Of A Merger: Consumer Reactions To Service Failures, Melinda A. Mclelland, Ronald E. Goldsmith

Journal of Applied Marketing Theory

Customers are often overlooked during the merger process in both reality and the marketing literature. This research features an experiment with 431 U.S. consumers that assesses the impact of a service failure following a merger on a variety of consumer behaviors. Key results indicate that consumers are more likely to switch service providers if they experience a failure of any magnitude (major/minor) following a merger than if they experience the same failure in the absence of a merger. This finding emphasizes that firms involved in service mergers have to be extremely diligent about preventing customer defection and implement focused marketing …

The Influences Of Brand-Consumer And Cause-Congruence On Consumer Responses To Cause Related Marketing, Ronald E. Goldsmith, Zhu Yimin

Journal of Applied Marketing Theory

Cause Related Marketing (CRM) is a widely used type of brand alliance in which companies donate a portion of their sales to social causes with whom they ally. Researchers have studied many aspects of CRM to learn why these programs are effective and how to enhance their success. An overlooked component in CRM research is the extent to which consumers identify with the brand and with the cause. The present study presented 604 U.S. college students with CRM campaigns for two brands (M&Ms and Crest) partnered with the World Wildlife Fund to assess whether brand-cause congruence, brand-consumer congruence, cause-consumer congruence, …

Physical Fitness And Body Mass Index As Predictors Of Academic Achievement, Kristin V. Sumrall

Honors Theses

In the United States, a significant portion of the population is overweight or obese. In addition to this, there are very low levels of physical fitness amongst the general population. However, in numerous studies healthy body weight and moderate to high levels of physical fitness have been linked with many benefits, including improved academic performance. This study focused on the relationship between physical fitness, body mass index, and academic achievement in college students at the University of Southern Mississippi. The aim of this study was to conduct a quantitative correlational analysis of these three factors in order to determine if …

Structure’S Impact On Homiletic Rhetoric: A Case Study Of Melissa Scott’S Preaching, Erik S. Nelson

Honors Theses

Though the connection between the study of rhetorical processes and the practice of expository preaching is obvious, academic cooperation between the two fields is lacking. This case study presents an example of the harmony achievable between the disciplines through the production of constructive criticism, a process known to communication scholars as rhetorical analysis, for a sample of sermons given by Pastor Melissa Scott in recent years. Scott, whose preaching style is uniquely centered on translation-based exposition, represents the modern pastor whose skill and technique might be improved upon with the implementation of recent and emerging communication theory. Specifically, this study …

Molecular Mapping Of Qtls For Domestication-Related Traits In Cowpea (V. Unguiculata (L.) Walp.), Mebeaselassie Andargie, Remy S. Pasquet, Bhavani S. Gowda, Geoffrey M. Muluvi, Michael P. Timko

All Peer-Reviewed Publications

Understanding the genetic basis underlying domestication-related traits (DRTs) of cowpea (Vigna unguiculata (L.) Walp.) is important since the genome has experienced divergent domestication and in addition it is also useful to utilize the wild germplasm efficiently for improving different traits of the cultivated cowpea. Quantitative trait loci (QTLs) for DRTs were identified in a population of 159 F7 recombinant inbred lines derived from a cross between a domesticated cowpea (V. unguiculata (L.) Walp.) variety, 524B, and a wild accession, 219. Using the constructed linkage map, QTLs for 10 DRTs were analysed and mapped. QTLs for seed, pod and flower related …

Psychometric Properties Of The Arabic Version Of The Perceived Physical Ability  Scale For Children In Oman, Sabry M. Abd-El-Fattah

Journal of Educational and Psychological Studies

This study aimed at examining the psychometric properties of the Perceived Physical Ability Scale for Children (PPASC) within an Omani context. A sample of 250 fourth graders (130 males and 120 females) from six public primary schools in four governorates in Oman responded to Arabic translated version of the PPASC. Data on students' in-class physical activity, social desirability, and teachers' nominations of students' physical ability were also collected. Confirmatory factor analysis revealed that the unidimensional model of the PPASC had adequate fit to the data. Multigroup CFA revealed gender invariance for PPASC unidimensional model when it was compared across male …

The Effect Of A Group Counseling Program Based On A Cognitive – Behavioral  Therapy On The Treatment Of Type A Behavior, Bakkar S. Bakkar, Mohammad T. Abuel-Ealeh

Journal of Educational and Psychological Studies

The purpose of this study was to examine the effect of a group counseling program based on cognitive – behavioral therapy on reducing the Type A behavior pattern. The study attempted to test the following hypothesis: participants who receive group counseling based on cognitive – behavioral therapy will report significant reduction in the Type A behavior pattern compared to participants in the control group who don't receive any kind of treatment. A Type A Behavior Scale (TABS) was constructed to assess the extent to which the subjects have Type A behavior. The sample consisted of 24 students selected based on …

Understanding Higher-Order Nonlocal Halo Bias At Large Scales By Combining The Power Spectrum With The Bispectrum, Shun Saito, Tobias Baldauf, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

Understanding the relation between underlying matter distribution and biased tracers such as galaxies or dark matter halos is essential to extract cosmological information from ongoing or future galaxy redshift surveys. At sufficiently large scales such as the baryon acoustic oscillation (BAO) scale, a standard approach for the bias problem on the basis of the perturbation theory (PT) is to assume the "local bias" model in which the density field of biased tracers is deterministically expanded in terms of matter density field at the same position. The higher-order bias parameters are then determined by combining the power spectrum with higher-order statistics …

Multiple Osteochondromas In A 16th–19th Century Individual From Setúbal (Portugal), Nathalie Antunes-Ferreira, Eugénia Cunha, Carina Marques

Anthropology Faculty Publications

An archaeological survey at the church of Nossa Senhora da Anunciada (Setúbal, Portugal) uncovered the remains of 92 individuals. Historical and archaeological data suggest that the inhumations occurred between 1531 and 1839. The present work reports the pathological features of a mature male individual exhibiting multiple osseous bony projections and bone deformity, mainly affecting the metaphyseal and adjacent diaphyseal regions of the long bones. The macroscopic and the radiological analyses of the lesions suggest multiple osteochondromas as the most probable diagnosis. This is the first archaeological case of this disease known on the Portuguese territory and in southern Europe.

Gradient-Based Compressive Sensing For Noise Image And Video Reconstruction, Huihuang Zhao, Yaonan Wang, Xiaojiang Peng, Zhijun Qiao

School of Mathematical & Statistical Sciences Faculty Publications

In this study, a fast gradient-based compressive sensing (FGB-CS) for noise image and video is proposed. Given a noise image or video, the authors first make it sparse by orthogonal transformation, and then reconstruct it by solving a convex optimisation problem with a novel gradient-based method. The main contribution is twofold. Firstly, they deal with the noise signal reconstruction as a convex minimisation problem, and propose a new compressive sensing based on gradient-based method for noise image and video. Secondly, to improve the computational efficiency of gradient-based compressive sensing, they formulate the convex optimisation of noise signal reconstruction under Lipschitz …

Connections Of Zero Curvature And Applications To Nonlinear Partial Differential Equations, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

A general formulation of zero curvature connections in a principle bundle is presented and some applications are discussed. It is proved that a related connection based on a prolongation in an associated bundle remains zero curvature as well. It is also shown that the connection coefficients can be defined so that the partial differential equation to be studied appears as the curvature term in the structure equations. It is discussed how Lax pairs and Bäcklund tranformations can be formulated for such equations that occur as zero curvature terms.

Prof. Akhtar Ahmed – A Memoir Of Love, Respect, Admiration, And..., Ismail A. Khatri

Pakistan Journal of Neurological Sciences (PJNS)

Prof. Akhtar Ahmed – a majzoob, how can it be. What an unusual analogy! I was kind of surprised when I heard this from one of my revered teachers Prof. Iftekhar Ahmed who happen to be one of the students of Prof. Akhtar Ahmed like me. However, when he explained this analogy it made complete sense. He explained that a majzoob throws stones on the salik and treats the salik harshly until he is confident that the salik can go through and endure the hardships on the path. Once satisfied, the majzoob opens up for the salik and the knowledge …
