Power System Fault Detection Using the Discrete Wavelet Transform and Artificial Neural Networks

This project focuses on detecting various phase to ground faults in three phase power systems. In this research, the faults are generated using a power distribution system simulator; and the three phase voltage waveforms are analyzed using the discrete wavelet transform. Multi-layer feed forward neural networks are employed for fault detection and classification. The effectiveness of this approach is demonstrated by computer simulation results

Form in the Manner of Landscape: Distillation of a Concept through Language and Literature

Past work on the concept of landscape developed the idea that landscape should be viewed less as a noun than as a verb. This develops the idea that ―landscape‖ can be explored as a concept through the fabric of the word itself. This thesis explores through the ambiguity of language, the potential of a landscape idea that considers landscape a verbal action and practice, but also something that retains the objective sense of a noun in abstract representational terms. The potential in landscape to embody paradoxical ideas of movement and substance brings about the consideration of landscape as a relationship of tensions. The visibly apparent expression of a landscape product is the result of their negotiation. There is no correct ―way‖ of doing landscape but the ways in which it is done may be read as apparent propositions towards an unapparent abstract ideal. Through circumstances in time and experience the proposition is renewed and transformed to express a new proposition. This cycle is at the core of a relationship between human and land. The coherence of diversity is its self-preservation. The idea of diversity ordinarily indicates an idea of landscape framed by deductive thought processes in the sense that disparate branches and off-shoots spread the concept so thinly that it can struggle to find conceptual significance. Considering an inductive approach that draws these disparate branches back into one idea of landscape prompts a renewal in focus, outlining a basic idea or form to which circumstantial performance relates. The thesis moves from the observation of a theoretical outline to the interpretation of that theory in lived experience and finally to its articulation in a particular way through personal reflection. This study seeks a form of landscape, finds meanings in its use, and then lives the form in a meaningful manner

AbstractLanguage always has a connection with the times. This is what causes the appearance of "AidoruKooru". The emergence of "Aidoru Kooru" began with the existence of Idol Group culture in the 1990s atan idol group concert, when the song was in the intro position, a group of fans cheered their idol as anappreciation for their performance and gave encouragement while on stage. Currently the development ofAidoru Kooru has spread throughout the world, this is what made Yoshiko Morishita write a Doramaentitled "Dakara Watashi wa Oshimashita". In this Dorama there is how Aidoru Kooru is made by fans andcan be accepted by groups of fans of different ages, occupations, and genders.Keyword: Sociolinguistic, Language Variation, Aidoru Kooru, Idol, Dorama, Fans.要旨言葉は時代にいつも繋がります。繋がるから“アイドルコール”があります。1990 年頃にアイドルグループのコンサートで歌がイントロに入る時にファン達がアイドルを応援を捧ぎます。そしてアイドルに褒めることを上げます。それがアイドルコールに呼んでいますが、あの時にアイドルコールはミックスと呼ばれます。今頃にはこのアイドルコールは世界中に広がっていますから、森下佳子さんがだから私は押しましたのドラマを書きます。このドラマにはファンからのアイドルコールの使い方とそして違う年齢や仕事や性別などのファン達受けられます。キーワード：社会言語学、言語変異、アイドルコール、アイドル、ドラマ、ファン

Meta-Analysis of Drosophila Circadian Microarray Studies Identifies a Novel Set of Rhythmically Expressed Genes

Five independent groups have reported microarray studies that identify dozens of rhythmically expressed genes in the fruit fly Drosophila melanogaster. Limited overlap among the lists of discovered genes makes it difficult to determine which, if any, exhibit truly rhythmic patterns of expression. We reanalyzed data from all five reports and found two sources for the observed discrepancies, the use of different expression pattern detection algorithms and underlying variation among the datasets. To improve upon the methods originally employed, we developed a new analysis that involves compilation of all existing data, application of identical transformation and standardization procedures followed by ANOVA-based statistical prescreening, and three separate classes of post hoc analysis: cross-correlation to various cycling waveforms, autocorrelation, and a previously described fast Fourier transform–based technique [1–3]. Permutation-based statistical tests were used to derive significance measures for all post hoc tests. We find application of our method, most significantly the ANOVA prescreening procedure, significantly reduces the false discovery rate relative to that observed among the results of the original five reports while maintaining desirable statistical power. We identify a set of 81 cycling transcripts previously found in one or more of the original reports as well as a novel set of 133 transcripts not found in any of the original studies. We introduce a novel analysis method that compensates for variability observed among the original five Drosophila circadian array reports. Based on the statistical fidelity of our meta-analysis results, and the results of our initial validation experiments (quantitative RT-PCR), we predict many of our newly found genes to be bona fide cyclers, and suggest that they may lead to new insights into the pathways through which clock mechanisms regulate behavioral rhythms

A professional development programme to enhance primary school teachers’ knowledge and operationalisation of physical literacy

Introduction: Despite increases in research and implementation, physical literacy continues to be largely misinterpreted by practitioners. The purpose of this study was to devise, implement, and evaluate a professional development programme that works in a primary school environment to enhance their knowledge and operationalisation of physical literacy. Methods: Following a three-month needs assessment phase, data were collected from structured observations, reflections, and semi-structured interviews with the teachers, before, during and after an introductory workshop and six-month physical literacy intervention. Thematic analysis was used to evaluate perceptions of programme effectiveness. Results: The needs assessment phase identified notable differences between teachers’ classroom and physical education practice. Results of the physical literacy workshop and intervention detailed an increase in teachers’ knowledge of, and operationalisation of, physical literacy. Discussion/Conclusions: Applying established principles of effective professional development in a contextually sensitive manner was viewed as effective in enhancing primary school teachers’ knowledge and practice regarding physical literacy

A monetary reward alters pacing but not performance in competitive cyclists

Money has frequently been used as an extrinsic motivator since it is assumed that humans are willing to invest more effort for financial reward. However, the influence of a monetary reward on pacing and performance in trained athletes is not well-understood. Therefore, the aim of this study was to analyse the influence of a monetary reward in well-trained cyclists on their pacing and performance during short and long cycling time trials (TT). Twentythree cyclists (6 ♀, 17 ♂) completed 4 self-paced time trials (TTs, 2 short: 4 km and 6 min; 2 long: 20 km and 30 min); in a randomized order. Participants were separated into parallel, non-randomized “rewarded” and “non-rewarded” groups. Cyclists in the rewarded group received a monetary reward based on highest mean power output across all TTs. Cyclists in the non-rewarded group did not receive a monetary reward. Overall performance was not significantly different between groups in short or long TTs (p \u3e 0.48). Power output showed moderatly lower effect sizes at comencement of the short TTs (Pmeandiff = 36.6 W; d \u3e 0.44) and the 20 km TT (Pmeandiff = 22.6 W; d = 0.44) in the rewarded group. No difference was observed in pacing during the 30 min TT (p = 0.95). An external reward seems to have influenced pacing at the commencement of time trials. Participants in the non-rewarded group adopted a typical parabolic shaped pattern, whereas participants in the rewarded group started trials more conservatively. Results raise the possibility that using money as an extrinsic reward may interfere with regulatory processes required for effective pacing

A Platform-Independent Method for Detecting Errors in Metagenomic Sequencing Data: DRISEE

We provide a novel method, DRISEE (duplicate read inferred sequencing error estimation), to assess sequencing quality (alternatively referred to as “noise” or “error”) within and/or between sequencing samples. DRISEE provides positional error estimates that can be used to inform read trimming within a sample. It also provides global (whole sample) error estimates that can be used to identify samples with high or varying levels of sequencing error that may confound downstream analyses, particularly in the case of studies that utilize data from multiple sequencing samples. For shotgun metagenomic data, we believe that DRISEE provides estimates of sequencing error that are more accurate and less constrained by technical limitations than existing methods that rely on reference genomes or the use of scores (e.g. Phred). Here, DRISEE is applied to (non amplicon) data sets from both the 454 and Illumina platforms. The DRISEE error estimate is obtained by analyzing sets of artifactual duplicate reads (ADRs), a known by-product of both sequencing platforms. We present DRISEE as an open-source, platform-independent method to assess sequencing error in shotgun metagenomic data, and utilize it to discover previously uncharacterized error in de novo sequence data from the 454 and Illumina sequencing platforms.</p

Validating an inertial measurement unit for cricket fast bowling: a first step in assessing the feasibility of diagnosing back injury risk in cricket fast bowlers during a tele-sport-and-exercise medicine consultation

This study aimed to validate an array-based inertial measurement unit to measure cricket fast bowling kinematics as a first step in assessing feasibility for tele-sport-and-exercise medicine. We concurrently captured shoulder girdle relative to the pelvis, trunk lateral flexion, and knee flexion angles at front foot contact of eight cricket medium-fast bowlers using inertial measurement unit and optical motion capture. We used one sample t-tests and 95% limits of agreement (LOA) to determine the mean difference between the two systems and Smallest Worth-while Change statistic to determine whether any differences were meaningful. A statistically significant (p < 0.001) but small mean difference of −4.7° ± 8.6° (95% Confidence Interval (CI) [−3.1° to −6.4°], LOA [−22.2 to 12.7], SWC 3.9°) in shoulder girdle relative to the pelvis angle was found between the systems. There were no statistically significant differences between the two systems in trunk lateral flexion and knee flexion with the mean differences being 0.1° ± 10.8° (95% CI [−1.9° to 2.2°], LOA [−22.5 to 22.7], SWC 1.2°) and 1.6° ± 10.1° (95% CI [−0.2° to 3.3°], LOA [−19.2 to 22.3], SWC 1.9°) respectively. The inertial measurement unit-based system tested allows for accurate measurement of specific cricket fast bowling kinematics and could be used in determining injury risk in the context of tele-sport-and-exercise-medicine
