Planetary gearbox torsional vibration effects on wound rotor induction generator electrical signatures

Recently, alternative non-invasive methods based on electrical signature analysis have been proposed as an effective, easy and cheap way for electrical and mechanical faults detection in complex electromechanical systems such as wind turbines and traction systems. This paper aims to study the torsional vibration effects of a planetary gearbox which is a vital component of wind turbines on the electrical signatures of a wound rotor induction generator through both numerical simulations and experiments. A lumped model of planetary gearbox which needs minimum number of mechanical parameters is linked to the classical model of wound rotor induction generator in abc reference frame. The numerical simulation results show that some of mechanical characteristic frequencies of the planetary gearbox can be identified in the electromagnetic torque and stator current signatures of wound rotor induction generator. A reduced scale wind turbine simulator based on a 5.5 kW wound rotor induction generator is used for experimental verification of the proposed model at different working conditions.
Patterns Linking Interpreting and Deciding How to Respond during the Launch of a Lesson: Noticing from an Integrated Perspective.

Researchers have generated a powerful framework that identifies three aspects of noticing students’ mathematical thinking: attending to, interpreting, and deciding how to respond to student thinking. Previous research has tended to focus on evaluating how well teachers engaged in noticing, and how well they connected the different aspects of noticing. We describe a complementary way of studying the connections between different aspects of noticing, one that stresses the content of teachers noticing. We report on a study in which participants were shown depictions of students reacting to the launch of a complex task. Participants then chose among a variety of possible interpretations and teacher responses. We found that participants displayed patterns in how they decided to respond to specific interpretations. We describe some of these patterns, as well as similarities and differences between secondary and elementary mathematics teachers. We argue that developing non-hierarchical categories for interpreting and deciding how to respond to student thinking, and describing patterns linking them, reflects how teachers engage in noticing and support teachers in learning how to notice more effectively.
The role of goal concordance on happiness and college students’ academic performance

For decades, studies on goal concordance had documented its significant role in individuals’ performance and success in many aspects of life. Previous researchers claimed that goal concordance buffers happiness (Sheldon & Elliot, 1999) and task performance (Deci & Ryan, 2000). But studies on the possible influence of goal concordance and happiness in academic context remained unclear, especially in the Philippine academic setting. To shed light on the remaining question in the literature, this study focused on determining the possible association between goal concordance and happiness with college students’ academic performance. The study was conducted at the Central Luzon State University in the Philippines. 300 college students participated in the current investigation. Using the correlational and test of difference analyses, this study had come up with several important findings. A significant relationship between goal concordance and academic performance was found. In addition, the significant association between happiness and academic performance was also noted. However, goal concordance and happiness had no significant relationship. Moreover, the finding shows a significant difference between the two groups of students: college students with self-concordant goals had higher academic performance than those with nonconcordant goals. Lastly, there is no significant difference in happiness between students with self-concordant and nonconcordant goals. Both practical and theoretical implications are discussed.
Evaluation of Candida Albicans Attachment with Two Types of Denture Base (Heat Cured Acrylic & Flexible Resin) Polished By Different Polishing Materials

Aims: This study aims to measure the effect of three different types of polishing materials (pumice, pumice with soap solution and universal polisher paste) on the surface roughness and the growth of Candida Alicans (C.A) on two types of denture base materials (heat cured acrylic and flexible thermoplastic resin). Materials and Methods: Ninety (90) samples with dimensions (3cm length, 3cm width & 1cm thickness) were prepared & divided into two main groups (45 samples in each) according to the type of base material, heat cured & flexible. Each group was subdivided into three subgroups (15 samples in each) according to the type of polishing materials used in this study: Group1: Polished with pumice (control group), Group 2: Polished with (pumice with soap solution), Group 3: Polished with universal polisher paste. Roughness was measured to all samples by Profilometer Tester. After that the samples were incubated in media containing C.A. for 72 hr. at 300 C to count and compare the value of C.A. growth & adhesion.Results: the statistical analysis of roughness test between the heat cured & flexible showed a highly significant differences between samples polished with pumice, t-test=10.594, p<0.01, and significant differences for both groups polished by (pumice + soap solution) & (polishing paste), t-test= 4.651 & 3.173 with p<0.05 respectively. And for both types (Heat cured & Flexible), samples polished with pumice have the lowest number of viable cells count of C.A. (54, 67 respectively) Conclusions: The heat cured acrylic resin samples had a smoother surface than flexible samples. (Pumice) produced smoother surface than (universal polishing paste) and (pumice +soap solution), therefore, C.A. adhesion were higher than samples polished with pumice.
Effect of Asparagus saponins on HepG2 Apoptosis and Mitochondrial Membrane Potential and ROS Level

To study the effect of Saponins of asparagus on HepG2 apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential (Δψm) levels. Saponins of asparagus with different concentration was treated with HepG2 at different time, MTT assay was used to detect inhibitory rate, fluorescence staining was used to observe apoptosis morphology, flow cytometry was used to detect apoptosis rate and cell cycle, also ROS and Δψm were measured by flow cytometry. The results showed Saponins of asparagus inhibited cell proliferation, the IC50 on HepG2 was 172.3 mg/L. Apoptosis morphology was observed by fluorescence microscope. The cell cycle of HepG2 was arrested at S phase, G2/M phase percent decreased. After 72h the treated group appeared apoptosis peak, and apoptosis rate with high dose group 30.94 ± 1.74%; After 48h the ROS in treated group increased with high dose group 77.7 ± 4.5%; and Δψm decreased with high dose group 77.8 ± 1.9%. Saponins of asparagus can induce HepG2 cell apoptosis, which is caused by increasing ROS and decreasing Δψm of HepG2.
Study of transformer resonant overvoltages caused by cable-transformer high-frequency interaction

Power transformers can fail from dielectric stresses caused by electromagnetic transients. In this paper we focus on a special phenomenon where excessive overvoltages arise due to resonance. This situation can take place when a transformer on the high-voltage side is connected to a cable and the low-voltage side is unloaded. Very high overvoltages can then result on the low-voltage side from transient events that cause a weakly attenuated overvoltage on the cable with a dominant frequency matching a resonance peak in the transformer voltage ratio. Laboratory tests on a 11 kV/230 V distribution transformer show that a step voltage excitation on a 27-m cable produces a 24 p.u. overvoltage on the open low-voltage side. The voltage waveforms are accurately reproduced by a black-box model obtained from frequency sweep measurements. Simulations show that overvoltages as high as 43 p.u. could occur with the most unfavorable cable length. It is further shown that the following situations can lead to high overvoltages on an unloaded transformer low-voltage side: 1) ground fault initiation at the far cable end, 2) cable energization from a busbar with several other cables connected, and 3) cable energization from another cable of same length.

Effectiveness of self management techniques to reduce truant students in middle school

Truancy is an undisciplined behavior in the form of absence in the learning process. This behavior is one form of student delinquency. It does not deal if truancy with it can have a bad impact and become a habit that led to students. Therefore, we need a technique or method to reduce truancy behavior. The technique of self management is one technique of changing behavior. Through selfmanagement techniques that are implemented, it is hope that individual truant behavior can be reduced. The purpose of this study was to determine the effectiveness of self-management techniques to reduce truant behavior. The research subjects were seven students of class VIII of Muhammadiyah Middle School 4 Singosari Malang. This research is a Quasi Experiment study using the Pretest-Posttest One Group design. The instrument used in this study was the scale of truant behavior, experimental guidelines, and observation guidelines. Data analysis using Wilcoxon (Wilcoxon’s Signed Rank Test). The results showed that the score of truant pre-test behavior was 31.2 (high category), while the post-test results showed a score of 17 (medium category). And based on the results of the Wilcoxon test got a significant of 0.018 <0.05 means that the effective self-management technique to reduce truancy behavior.
Nanoscale characterization of ferroelectric materials by scanning probe microscope under ultrahigh vacuum

The downsizing trend in multilayer ceramic capacitors (MLCCs) will reach a limit as long as a conventional way of materials development continues. Creation of advanced materials and precise control of materials properties will be a key technology to break through the current situation. To address this issue, scanning probe microscopy under ultrahigh vacuum (UHV-SPM) is employed to clarify materials properties from nanoscale perspective. Kelvin probe force microscopy allows us to obtain surface potential mapping on degraded dielectrics with highly spatial resolution, which is promising to consider degradation mechanism of MLCCs. Piezoresponse force microscopy enables not only to evaluate size dependent properties of ferroelectric nanoislands but also to investigate temperature dependence of domain images in Sn doped strontium titanate ceramics. Characterization of ferroelectrics based on UHV-SPM will open a new way to design future MLCCs.
The experiences and feelings of general nurses working at a Maltese psychiatric hospital : a Heigeggerian interpretive phenomenological study

The purpose of this study was to gain an understanding of the feelings and experiences of general nurses working at a Maltese psychiatric hospital, which had not been addressed in published literature to date. A Heideggerian interpretive approach was adopted for this study. A purposive sample of six nurses was chosen and data was collected through semi-structured interviews. The data was analysed in accordance to Colaizzi's (1978 cited in Knaack, 1984 and quoted by Smith, 1996: 77). Three broad interrelated themes emerged from the data. These were related to psychiatric nursing practice, hospital culture and the meaning of nursing to nurses. Findings were discussed in relation to them and their related concepts. The study's findings suggested how general nurses providing care to patients at this hospital, viewed their world. They are considered to contribute to a greater understanding of feelings and experiences of general nurses working at this hospital. Recommendations were made to ensure that the needs of these nurses are addressed, thus enhancing their ability to care for their patients and influence the latter's health outcomes favourably.
Effect of nitrobenzene on growth and yield of boro rice

The present experiment was conducted at the research field of Patuakhali Science and Technology University (PSTU), Patuakhali during the period from December 2013 to March 2014 to evaluate the effect of Nitrobenzene as plant growth regulators on growth and yield parameters of Boro Rice. It also observed the comparative growth and yield performance of foliar application Nitrobenzene ( 0, 1.0, 3.0 and 5.0 ml L–1). Data were collected on Plant height; number of leaves plant–1; number of total, effective and non–effective tillers hill–1; leaf area (LA); leaf area index (LAI); total dry matter (TDM); Crop and relative growth rate (CGR and RGR); and Yield and yield contributing characters such as length of root; length of panicle; number of total, sterile and non–sterile spikelets panicle–1; 1000–grain weight; grain, straw and biological yield and harvest index (HI). The experiment was laid out in a completely randomized block design (RCBD) with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. The treatments Nitrobenzene @ 3.0 ml L–1 as foliar application gave the highest performance in respect of plant height (90.39 cm), LAI (3.514), TDM (19.17 g plant–1), effective tiller (20.33 hill–1), total tillers (22.73 hill–1), panicle length (26.01 cm),non sterile spikelets (134.70 panicle–1), total spikelets (155.80 panicle–1), 1000–grain weight (28.21 g), grain yield (5.86 t ha–1), straw yield (8.44 t ha–1), biological yield (14.29 t ha–1) and HI (41.00%) of boro rice.

WEIGHT DISTRIBUTION AND DECODING OF CODES ON HYPERGRAPHS

Codes on hypergraphs are an extension of the well-studied family of codes on bipartite graphs. Bilu and Hoory (2004) constructed an explicit family of codes on regular t-partite hyper-graphs whose minimum distance improves earlier estimates of the distance of bipartite-graph codes. They also suggested a decoding algorithm for such codes and estimated its error-correcting capability. In this paper we study two aspects of hypergraph codes. First, we compute the weight enu-merators of several ensembles of such codes, establishing conditions under which they attain the Gilbert-Varshamov bound and deriving estimates of their distance. In particular, we show that this bound is attained by codes constructed on a fixed bipartite graph with a large spectral gap. We also suggest a new decoding algorithm of hypergraph codes that corrects a constant fraction of errors, improving upon the algorithm of Bilu and Hoory.
Generating Image Captions in Arabic using Root-Word Based Recurrent Neural Networks and Deep Neural Networks

Image caption generation has gathered widespread interest in the artificial intelligence community. Automatic generation of an image description requires both computer vision and natural language processing techniques. While, there has been advanced research in the English caption generation, research on generating Arabic descriptions of an image is extremely limited. Semitic languages like Arabic are heavily influenced by root-words. We leverage this critical dependency of Arabic to generate captions of an image directly in Arabic using root-word based Recurrent Neural Network and Deep Neural Networks. Experimental results on dataset from various Middle Eastern newspaper websites allow us to report the first BLEU score for direct Arabic caption generation. We also compare the results of our approach with BLEU score captions generated in English and translated in Arabic. Experimental results confirm that generating image captions using root-words directly in Arabic significantly outperforms the English-Arabic translated captions using state-of-the-art methods.
Examining the Role of Race and Gender as Moderators of the Relationship Between Depressive Symptoms and Hazardous Alcohol Consumption among DUI Offenders

Abstract Research consistently documents a positive association between depressive symptoms and hazardous drinking. Fewer studies have examined this relationship among high-risk populations such as Driving Under the Influence (DUI) offenders and rarely evaluate whether the association between depression and hazardous drinking varies by race and gender. We examined the relationship between depressive symptoms and hazardous drinking in a diverse sample of DUI offenders, extending previous research by examining the moderating effects of race and gender. We analyzed survey data collected from DUI offenders (N = 10,082) enrolled in the 2012 Mississippi Alcohol and Safety Education Program. We estimated a series of nested regression models to assess the relationship between depressive symptoms and hazardous drinking. The analyses also assessed the extent to which the hypothesized association between depression symptomology and hazardous drinking varied by race and gender. We documented a positive association between depressive symptoms and hazardous drinking among DUI offenders. The association between depressive symptoms and hazardous drinking was stronger for black offenders relative to white. We found no significant differences by gender. The incorporation of culturally specific needs of DUI offenders may help intervention efforts more efficiently reduce negative consequences associated with impaired driving.
Big Five Personality Factors Among Men With a Sexual Interest in Children

Abstract Men with a sexual interest in children or adolescents have been described as less extraverted, conscientious, and emotionally stable than controls. Yet, such studies have mostly been conducted in forensic institutions. To test whether such findings generalize to community samples, we assessed personality profiles of 123 German-speaking men with and 89 men without pedohebephilia online, using the Big Five Inventory-25. Our results indicate that men with pedophilia or hebephilia are less emotionally stable and extraverted but more conscientious than controls. We discuss study limitations and potential causes for differences in personality among community samples of men with and without pedohebephilia.
Enhancing antioxidant activity and extractability of bioactive compounds of wheat bran using thermal treatments

Wheat bran contains a diverse collection of macronutrients, micronutrients and bioactive components, including those thought to have an important role in reducing the risk of many chronic diseases. Wheat bran contains very significant levels of dietary fibre, phenolic compounds, phytate and lesser amounts of other micronutrients and phytochemicals such as B vitamins, minerals, lignans, sterols, and alkylresorcinols, all of which can provide health benefits beyond nutrition which is the basis for the characterization of wheat bran as a functional food. In particular, it is the antioxidant activity associated with many of the phytochemicals of wheat bran that has received considerable attention over the past decade with regard to functional properties and health benefits. The complication of wheat bran as a functional food relates to its high insoluble fibre content, typically in the neighbourhood of 50%, which renders bran and its constituent bioactives largely indigestible, and hence with limited bioavailability until passage through the large intestine where the bran can be broken down by bacteria. Presumably, if the solubility of wheat bran could be enhanced by pre-treatment, its biological impact associated with its fibre and resident phytochemicals would also be enhanced. Among the treatments reported in the literature on wheat bran and analogous grain products, such as roasting, boiling, steaming, microwave heating and autoclaving, it is the latter that appears to provide some of the more interesting effects, although there have been very few studies. As well, because all digestive secretions are aqueous in nature, an underlying rationale for this thesis research is the use of aqueous extracts of wheat bran as the starting
The Neurocognition of Translation and Interpreting

This groundbreaking work offers a comprehensive account of brain-based research on translation and interpreting. First, the volume introduces the methodological and conceptual pillars of psychobiological approaches vis-a-vis those of other cognitive frameworks. Next, it systematizes neuropsychological, neuroscientific, and behavioral evidence on key topics, including the lateralization of networks subserving cross-linguistic processes; their relation with other linguistic mechanisms; the functional organization and temporal dynamics of the circuits engaged by different translation directions, processing levels, and source-language units; the system’s susceptibility to training-induced plasticity; and the outward correlates of its main operations. Lastly, the book discusses the field’s accomplishments, strengths, weaknesses, and requirements. Its authoritative yet picturesque, didactic style renders it accessible to researchers in cognitive translatology, bilingualism, and neurolinguistics, as well as teachers and practitioners in related areas. Succinctly, this piece establishes a much-needed platform for translation and interpreting studies to fruitfully interact with cognitive neuroscience.
Antecedents of Audit Quality in MENA Countries: The Effect of Firm- and Country-Level Governance Quality

Abstract This paper investigates the effect of firm- and country-level governance quality on audit quality, as measured by (i) auditor choice and (ii) audit fees. Our findings are three-fold. First, our evidence suggests that board independence is positively related to engaging a Big 4 auditor, while family shareholdings show a negative association with hiring a Big 4 auditor. Second, board size, board independence, and director shareholdings are positively related to audit fees, while government shareholdings and family shareholdings show a negative relationship with audit fees. Third, higher country-level governance quality is positively associated with hiring a Big 4 auditor and paying higher audit fees. Overall, we provide evidence that external audit quality in Middle Eastern and North African (MENA) countries is affected by firm- and country-level governance quality, which suggests that governance quality and external audit quality seem to be complements in protecting stakeholders interests through securing higher audit quality. Our results are robust to controlling for alternative measures and endogeneities.
