Fork-Connected Autotransformer Based 30-Pulse AC-DC Converter for Power Quality Improvement

This paper presents the design and analysis of a novel T-connected autotransformer based 30-phase ac-dc converter which supplies direct torque controlled induction motor drives (DTCIMD's) in order to have better power quality conditions at the point of common coupling. The proposed converter output voltage is accomplished via three paralleled 10-pulse ac-dc converters each of them consisting of 5-phase diode bridge rectifier. A T-connected autotransformer is designed to supply the rectifiers. This autotransformer makes use of only two single-phase transformers, resulting in reduced volume, weight, and the cost of the drive as compared with polygon structure. The design procedure of magnetics is in a way such that makes it suitable for retrofit applications where a six-pulse diode bridge rectifier is being utilized. The proposed converter requires only three inter-phase transformers in the dc link that yields in the reduced kilovolt ampere rating, size, weight, and cost of the proposed rectifier. The aforementioned structure improves power quality criteria at ac mains and makes them consistent with the IEEE-519 standard requirements for varying loads. Furthermore, near unity power factor is obtained for a wide range of DTCIMD operation. A comparison is made between 6-pulse and proposed converters from view point of power quality indices. Results show that input current total harmonic distortion (THD) is less than 3% for the proposed topology at variable loads.
Prosocial Orientation of an Organisation: The Preliminary Identification of Evaluation Criteria

Prosocial orientation of an organisation consists in such organising of an activity, in which universal social values aretaken on as valuation criteria and evaluations of economic activities. In this case, a social dimension of economicactivities constitutes an important aspect of implementation of a strategy and improving competitiveness of anorganisation. Practical solutions including social aspects in an organisation’s activity are not satisfactory enough.Organisations do not have sufficient determinants for developing prosocial orientation facilitating economicrationality. The aim of the article is to present major signs of prosocial activity of an organisation and exemplificationresearch verifying those activities as determining and evaluating factors of a degree of prosocial orientation in anorganisation’s activity. On the basis of a review of the literature from the field of taking socially responsible actionsby an organisation, an author’s classification of prosocial actions has been formulated. Four areas of such actionshave been distinguished i.e.: 1. reliable implementation of qualitative requirements, 2. improvement of activitiesthrough elimination of losses, 3. axiological orientation of managers’ attitudes, 4. subjective treatment ofemployees.The method and results of research verifying presence of indicated activities in functioning of anexemplary organisation with market leadership in its sector have been presented. A high degree of prosocialinvolvement in the examined organisation and the relation between presented types of activities and general state ofprosocial engagement have been stated. “A participation” of the areas selected to examination has been initiallyconfirmed as really examining the prosocial orientation of an organisation. Thus, an initial justification forformulating overall evaluation of prosocial involvement on their basis has been obtained. A dominant role ofsubjective treatment of employees in development of analysed phenomenon and in taking all kinds of sociallyresponsible actions has also been confirmed.
Modeling Market Downside Volatility

We propose a new methodology for modeling and estimating time-varying downside risk and upside uncertainty in equity returns and for assessment of risk--return trade-off in financial markets. Using the salient features of the binormal distribution, we explicitly relate downside risk and upside uncertainty to conditional heteroskedasticity and asymmetry through binormal GARCH (BiN-GARCH) model. Based on S&P 500 and international index returns, we find strong empirical support for existence of significant relative downside risk, and robust positive relationship between relative downside risk and conditional mode.

Genre and discourse community

Over the last decade, increasing attention has been given to the notion of genre in scientific/academic discourse and its applications in language teaching and learning. This interest has been mainly driven by the desire to understand how individuals use language to interpret and respond to communicative situations and the ways these uses change over time. However, the concept of genre and its relationship to discourse community has been viewed in distinct ways by researchers in different scholarly traditions. The aim of this paper is to provide a review of the current genre-based approaches and pedagogical applications in the main research traditions where genre studies have been developed, i.e. Systemic Functional Linguistics, North American New Rhetoric studies, and the English for Specific Purposes tradition.
Taste or reputation: what drives market prices in the wine industry? Estimation of a hedonic model for Italian premium wines

The aim of this article is to provide new evidence on the factors affecting wine prices on both methodological and factual grounds. On the methodological ground, this study is the first to apply a general Box–Cox transformation within the context of hedonic models which exploit all the variables (objective and sensorial characteristics, reputation) pointed out by previous literature as relevant in driving market prices. On the factual ground, the article fills the lack of empirical evidence on the issue for Italy, one of the leading wine producers, by using a large data set on two premium quality wines (Barolo and Barbaresco) covering the 1995–1998 vintages. Our results support the evidence obtained using data from other countries, showing that sensorial traits, the reputation of wines and producers, as well as objective variables are all important factors influencing the consumers' willingness to pay. More importantly, by resorting to a nonnested statistical test (Vuong, 1989) we compare two alternative specifications (taste vs. reputation) and find that the reputation model significantly outperforms the taste one, whereby suggesting that a greater amount of information on how the wine price is formed is contained in the reputation specification.
The relationship between electronic readiness and corruption reduction: Countrywide data analysis

Abstract This study analyzed whether or not there is any correlation between the level of electronic readiness (e-readiness) and corruption in countries. The study was guided by the theory of network society, the Unified Theory of Acceptance and Use of Technology (UTAUT) as well as Technology Acceptance Model (TAM). The study opted for secondary data from 147 countries of the world for both measures of e-readiness (Global Information Technology) and corruption perception index (from Transparency International) for 2014. Statistical analysis was done using correlation and regression analyses. Four sub measures for e-readiness included networked readiness index, environment readiness index, society readiness index, and usage readiness index (independent variables). Results from the study showed there is correlation between the two variables. Based on the objective of this study, it is concluded that the higher the e-readiness, the low the corruption. This implies that one way of combating corruption is to attain good e-readiness index.
Morphological and molecular data to describe a hybrid population of the Common toad ( Bufo bufo ) and the Spined toad ( Bufo spinosus ) in western France

The use of hyper-variable markers across species is often hin- dered by low cross-species amplification success, a reduced level of polymorphism or a high frequency of null alleles. How- ever, optimizing sets of reliable and informative markers that can be consistently amplified and scored across taxa is key to address questions about patterns of genetic diversity and structure, hybridization and speciation. Here we present 14 newly developed microsatellite markers in the Spined toad ( Bufo spinosus ), assess their polymorphism in two Iberian populations and test for cross-species amplification in the closely related Common toad ( Bufo bufo ). We then use the 12 loci co-amplify-ing in both species to the study of a morphologically intermedi- ate population (Moyaux) from the contact zone in northwest France as well as reference populations of the two species from both sides of the contact zone. Individuals from Moyaux had mtDNA haplotypes of the two species and were identified as hybrids in analyses with software NewHybrids. These results provide solid evidence for ongoing hybridization between B. bufo and B. spinosus , with no apparent restrictions to gene flow.
Numerical simulation of tower rotor interaction for downwind wind turbine

Downwind wind turbines have lower upwind rotormisalignment, and thus lower turning moment and self-steered advantage over the upwind configuration. In this paper, numerical simulation to the downwind turbine is conducted to investigate the interaction between the tower and the blade during the intrinsic passage of the rotor in the wake of the tower. The moving rotor has been accounted for via ALE formulation of the incompressible, unsteady, turbulent Navier-Stokes equations. The localized Cp, CL, and CD are computed and compared to undisturbed flow evaluated by Panel method. The time history of the Cp, aerodynamic forces (CL and CD), as well as moments were evaluated for three cross-sectional tower; asymmetrical airfoil (NACA0012) having four times the rotor's chord length, and two circular cross-sections having four and two chords lengths of the rotor's chord. 5%, 17%, and 57% reductions of the aerodynamic lift forces during the blade passage in the wake of the symmetrical airfoil tower, small circular cross-section tower and large circular cross-section tower were observed, respectively. The pronounced reduction, however, is confined to a short time/distance of three rotor chords. A net forward impulsive force is also observed on the tower due to the high speed rotor motion.
A Method of Deduplication based on Inconsistency

Reducing the number of comparisons is the most common way to improve the effectiveness of data cleaning. We investigate the problem by using inconsistency. We split redundant data into three categories. For each category, we give an algorithm and analyze its complexity, and combine them together finally. In particular, we address the chasing problem for the method under functional dependency. At the last, we experimentally verify that these algorithms effective and scale well, and that the method helps us more efficiently detecting duplications.
Interictal to ictal transition in human TLE: insights from a computational model of intracerebral EEG Abbreviated title: Model-based study of interictal to ictal transition in TLE

In human partial epilepsies, as well as in experimental models of chronic and/or acute epilepsy, the role of inhibition and the relationship between the inhibition and excitation and epileptogenesis has long been questioned. Besides experimental methods carried out either in vitro (human or animal tissue) or in vivo (animals), pathophysiological mechanisms can be approached by direct recording of brain electrical activity in human epilepsy. Indeed, in some clinical pre-surgical investigation methods like stereoelectroencephalopraphy (SEEG), intracerebral electrodes are used in patients suffering from drug resistant epilepsy to directly record paroxysmal activities with excellent temporal resolution (in the order of one millisecond). The study of neurophysiological mechanisms underlying such depthEEG activities is crucial to progress in the understanding of the interictal to ictal transition. In this study, we relate electrophysiological patterns typically observed during the transition from interictal to ictal activity in human mesial temporal lobe epilepsy (MTLE) to mechanisms (at a neuronal population level) involved in seizure generation through a computational model of EEG activity. Intracerebral EEG signals recorded from hippocampus in five patients with MTLE during four periods (during interictal activity, just before seizure onset, during seizure onset and during ictal activity) were used to identify the three main parameters of a model of hippocampus EEG activity (related to excitation, slow dendritic inhibition and fast somatic inhibition). The identification procedure used optimization algorithms to minimize a spectral distance between real and simulated signals. Results demonstrated that the model generates very realistic signals for automatically identified parameters. They also showed that the transition from interictal to ictal activity can not be simply explained by an increase in excitation and a decrease in inhibition but rather by time-varying ensemble interactions between pyramidal cells and local interneurons projecting to either their dendritic or perisomatic region (with slow and fast GABAA kinetics). Particularly, during preonset activity, an increasing dendritic GABAergic inhibition compensates a gradually increasing excitation up to a brutal drop at seizure onset when faster oscillations (beta and low gamma band, 15 to 40 Hz) are observed. These faster oscillations are then explained by the model feedback loop between pyramidal cells and interneurons targeting their perisomatic region. These findings obtained from
Intertidal barnacles as indicators of the intensity of scour by sea ice

We investigated the potential utility of intertidal barnacles as ecological indicators of the intensity of ice scour on the Gulf of St. Lawrence coast of Nova Scotia, Canada. This coast is exten- sively covered by sea ice in winter. Shortly after ice melt, between May and June 2007, we quantified the density of adult barnacles Semibalanus balanoides in the high intertidal zone in 8 rocky locations distributed along nearly 25 km of coastline. At each location, we took measurements in 2 types of habitat that differ in ice scour intensity: habitats facing open waters, where ice scour is intense, and habitats facing a rocky land mass between a few meters and 10s of meters away, where ice scour is moderate. Adult barnacle density was significantly higher in sheltered sites than in exposed sites by a factor of 3, on average. Ice scour intensity is likely the main factor determining such a pattern, as we previously found that barnacle recruitment is similar in both types of habitat and that the poten- tial competitors (algae and mussels) and predators (whelks) are virtually absent in the high intertidal zone. Thus, high-intertidal barnacles might serve as indicators of differences in ice scour intensity among coastal sites in our region. Future studies should determine the spatial scales of applicability of this approach.
The Seven Traits of a Learning Environment: A Framework for Evaluating Mobile Learning Engagement

Mobile technology is increasingly used both in and out of school classrooms by students to remain actively engaged in learning and extend their learning. Developments in mobile technology have made it possible to access and interact with learning resources, other learners and teachers in ways not possible just a few years ago. Instructional designers and teachers struggle to maintain understandings of how changes in technology impact student interactions and learning engagement. Instead of focusing on particular tools, instructional designers and teachers should focus on the design of the learning environment to gain understanding of what students are doing while engaged in learning. The Seven-Traits of a Learning Environment framework is introduced here to help educators develop more effective and engaging instructional design for mobile learning environments. The SAMR technology integration model is discussed as a potential tool to help measure student engagement through the lens of the 7-Traits framework.
A Miocene (8-12 Ma) intermediate water benthic stable isotope record from the northeastern Atlantic, ODP Site 982

[1] Oxygen and carbon isotope records are presented for the benthic foraminifer Cibicidoides wuellerstorfi from upper middle through lower upper Miocene (11.6–8.2 Ma) sediments recovered at intermediate water depth (1134 m) at Ocean Drilling Program Site 982 on Rockall Plateau. Oxygen isotopic values generally lighter than those for the Holocene indicate significantly warmer intermediate waters and/or less global ice volume during the late middle to early late Miocene than at the present. The most depleted oxygen isotope values occurred at around 10.5 Ma. After this time a long-term increase in δ18O suggests a gradual increase in global ice volume and/or cooling of intermediate waters during the late Miocene. Comparison of the intermediate depth benthic foraminiferal carbon isotope record from Site 982 and records from various North Atlantic deep sites shows that intermediate waters were generally better ventilated than deep waters between 11.6 and 9.6 Ma. During this time period, increased ventilation of intermediate waters was linked to cooling or the build up of polar ice caps. The Mi events originally proposed by Miller et al. [1991b] and Wright and Miller [1992] are difficult to identify with certainty in sediments sampled at high resolution (<104 year). Comparison of the high-resolution benthic δ18O records from ODP Site 982 with the low-resolution benthic δ18O record from Monte Gibliscemi (Mediterranean) show that Mi events, if real, may not be of importance as a stratigraphic tool in upper Miocene sedimentary sequences.
The effects of bisphosphonates and COX-2 inhibitors on the bone remodelling unit

Bone remodelling occurs in humans throughout life, therefore bone is continuously renewed to better respond to changes in weightbearing circumstances. Bone remodelling is extremely vulnerable during fracture healing and integration of prostheses into the surrounding bone. Bone remodelling is a complex system in which many growth factors, cytokines and enzymes, which are essential for the differentiation of osteoblasts and osteoclasts, are involved. Some widely used drugs can affect this sensitive system of remodellation in unexpected manner. Painkillers such as cyclooxygenase (COX) inhibitors have been demonstrated in animal studies to interfere with fracture healing and a few retrospective clinical studies confirm these observations. Bisphosphonates (BP), main target of which is the bone resorbing osteoclast, have been suggested to be the drug of choice to improve periprosthetic bone density and thus prevent aseptic loosening of implants. The exact mechanism of action of clodronate (CLO), a non-amino-BP, which was selected for the study, has not been clarified thus far. In order to gain a deeper understanding of the role of the COX enzyme in the differentiation of osteoblasts we studied human mesenchymal stem cell (hMSC) cultures in the presence of different COX-inhibitors; indomethacine, parecoxib and NS398, a specific COX-2 inhibitor. We used the liposome encapsulated CLO metabolite (AppCCl2p) to study in detail the mechanism of BP induced apoptosis in osteoclast. The effects of different BPs CLO, pamidronate (PAM) and zoledronic acid (ZOL), on the differentiation of osteoblasts and osteoclasts were tested in vitro. The optimal concentration for in situ CLO rinsing in clinical study was found. Finally, the effects of in situ and per oral CLO on the periimplant bone density and integration of prostheses were studied in vivo. All tested COX-inhibitors significantly inhibited osteoblast differentiation from hMSCs and stimulated the differentiation of adipocytes. It was also demonstrated that AppCCl2p inhibits mitochondrial function by a mechanism that involves competitive inhibition of ADP/ATP translocase. In the comparison of BPs, ZOL seemed to posses the properties of both non-aminoand amino-BPs and it thus belongs to a new class of BPs. Peroral and in situ CLO seemed to have different mechanisms of action. Peroral CLO delayed the integration of prosthesis to the bone and increased peri-implant osteolysis while is situ CLO accelerated integration. In conclusion, we can alter normal bone remodellation during fracture healing and prosthesis integration. On the other hand, we can also improve the circumstances for the integration of implant to the surrounding bone by in situ BP rinsing, thus creating a better environment for bone ingrowth.
Educational attainment: a French-German comparison

This documentation analyses the structure of educational attainment in France and Germany. While France and Germany share in many respects similar socioeconomic structures, they sharply differ with respect to their educational system. First, the three-tiered secondary school system in Germany, where pupils are streamed after primary schooling according to their learning ability into different secondary schools, contrasts with the situation in France, where all pupils attend a single structure up to upper secondary level. Moreover, in France, general education is more prized than vocational education. The French maturity certificate, has a key position in the educational system, while vocational education tends to be reserved to those pupils who have failed on the way to maturity completion. By contrast, the German education system is strongly oriented towards vocational training and the apprenticeship has a central position. At the higher education level, a relatively homogenous system in Germany can be opposed to a much more differentiated landscape in France, both in terms of types of institutions and of gradation of educational credentials.
The supernova remnant W49B as seen with H.E.S.S. and Fermi-LAT

The supernova remnant (SNR) W49B originated from a core-collapse supernova that occurred between one and four thousand years ago, and subsequently evolved into a mixed-morphology remnant, which is interacting with molecular clouds (MC). γ-ray observations of SNR/MC associations are a powerful tool to constrain the origin of Galactic cosmic-rays, as they can probe the acceleration of hadrons through their interaction with the surrounding medium and subsequent emission of non-thermal photons. The detection of a γ-ray source coincident with W49B at very high energies (VHE; E > 100 GeV) with the H.E. S.S. Cherenkov telescopes is reported together with a study of the source with 5 years of Fermi-LAT high energy γ-ray (0.06 - 300 GeV) data. The smoothly-connected combined source spectrum, measured from 60 MeV to multi-TeV energies, shows two significant spectral breaks at 304±20 MeV and 8.4+2.2−2.5 GeV, the latter being constrained by the joint fit from the two instruments. The detected spectral features are similar to those observed in several other SNR/MC associations and are found to be indicative of γ-ray emission produced through neutral-pion decay.
COMPARATIVE STUDY OF STATISTICAL TOOLS FOR SPATIAL DATA MINING

The main objective of this study is to discuss about various statistical techniques for spatial data and various analysis are conducted by using the tools GeoDa and SaTScan. The various spatial statistical methodologies are obtained from the Indian sub districts administrative data sets by using Geoda as well as SaTScan tools. Several interesting results and comparisons are attained from the results. From the results it is found that GeoDa happens to be the best among the tools in predicting effective and efficient statistical results. It is amazing to note the drawbacks of SaTScan clearly through our results which will certainly help the upcoming researchers too.
