Distribution network reconfiguration using genetic algorithm and load flow

There are various ways of reducing active power losses in distribution networks. Network reconfiguration is one of the most important methods. However, it can be a very difficult optimisation problem. The proposed Genetic Algorithm with Rank Weight selection is used to search the population for the optimum solution in the network. The chromosome is represented by a string of binary numbers (zeroes, 0s and ones, 1s). By opening one switch in each loop (fundamental loop approach), almost all the solutions will be feasible (radial networks). By doing this the chromosome will only consist of the open switches (Genotype); thus reducing the computation time. Constraints are used to filter the search by means of penalty factors, which guarantees the solution found by the Genetic Algorithm to be feasible.
Theoretical Study of Induction Pump for Molten Metal Using Rotating Twisted Magnetic Field

In this paper, the electromagnetic field in an induction pump for molten metal using rotating twisted magnetic field is theoretically analyzed. Asymptotic analysis for small magnetic Reynolds number clarifies that temporal mean value of the axial driving force f̅z is almost uniform but rather small when the twist ratio ka2 is considerably smaller than 1. On the other hand, when ka2 is larger than 1, f̅z near the outer boundary of the secondary conductor is large, whereas f̅z around the central axis is very small. Such a nonuniform force is not suitable for driving fluids in the pump. Performance of the pump is estimated when the magnetic Reynolds number is always adjusted to a desired value by automatic control of frequency of power supply. The optimal value of the twist ratio ka2 for the developed pressure is obtained. The ratio of the stator radius a1 to the secondary-conductor radius a2 has to be reduced to a value as small as possible in the hostile thermal environment by the molten metal. When the system is scaled up, the developed pressure is proportional to both a2 and the axial length h of the stator. The estimation results give bases for designing the pump system and required specification of the power supply.
Ethics in the supervisory relationship: supervisors' and doctoral students' dilemmas in the natural and behavioural sciences

This study explored the perceptions of ethical issues in supervision among doctoral students and supervisors. The nature of ethical issues identified by doctoral students (n = 28) and their supervisors (n = 14) is explored and the degree of fit and misfit between their perceptions in two cases representing the natural and behavioural sciences is analysed. Supervisors and students identified different ethical issues, which suggest that there are aspects in the supervisory relationship about which there is no shared understanding. There were also differences between the ethical issues emphasised in the natural sciences from those emphasised in the behavioural sciences, suggesting differences between the domains.
Six-Plate Capacitive Coupler to Reduce Electric Field Emission in Large Air-Gap Capacitive Power Transfer

This paper proposes a six-plate capacitive coupler for large air-gap capacitive power transfer to reduce electric field emissions to the surrounding environment. Compared to the conventional four-plate horizontal structure, the six-plate coupler contains two additional plates above and below the inner four-plate coupler to provide a shielding effect. Since there is a capacitive coupling between every two plates, the six-plate coupler results in a circuit model consisting of 15 coupling capacitors. This complex model is first simplified to an equivalent three-port circuit model, and then to a two-port circuit model which is used in circuit analysis and parameter design. This six-plate coupler can eliminate the external parallel capacitor in the previous LCLC topology, which results in the LCL compensation and reduces the system cost. Due to the symmetry of the coupler structure, the voltage between shielding plates is limited, which reduces electric field emissions. Finite element analysis by Maxwell is used to simulate the coupling capacitors and electric field distribution. Compared to the four-plate horizontal and vertical structures, the six-plate coupler can significantly reduce electric field emissions and expand the safety area from 0.9 to 0.1 m away from the coupler in the well-aligned case. A 1.97 kW prototype is implemented to validate the six-plate coupler, which achieves a power density of 1.95 kW/m2 and a dc–dc efficiency of 91.6% at an air-gap of 150 mm. Experiments also show that the output power maintains 65% of the well-aligned value at 300 mm X misalignment, and 49% at 300 mm Y misalignment.
The private-public divide: impact of conflicting perceptions between the private and public health care sectors in India.

SETTING India's private health care sector manages half the nation's tuberculosis (TB) patients, accounting for an estimated sixth of global TB cases. While several studies have demonstrated private physicians' dubious diagnosis and treatment styles and lack of cooperation with public physicians, very little is still known about the private sector. OBJECTIVES Using a detailed questionnaire to randomly survey private and public practitioners in Ahmedebad, Gujarat, India, we quantified perceptions held by each sector. STUDY DESIGN Cross-sectional survey of private and public physicians. RESULTS Significant conflicts in perception were found regarding interpretation of general facts, attitudes towards each sector, and effectiveness and social implications of DOTS. We also found that such differences in perception were likely to result in mistrust, differing views on reform propositions, conflicting mindsets about social agendas, and unwillingness to cooperate. CONCLUSION Our data suggest that reconciliation is attainable by obtaining and distributing unbiased, evidence-based information and exposing physicians to both private and public health care sectors in a professional setting.
The Paradox of Nationalism: The Common Denominator of Radical Left and Radical Right Euroscepticism

This paper asks what explains similar Eurosceptic positions between radical right and radical left parties. In answering this question, it focuses on the paradoxical role of nationalism as an integral part of the discourse of both radical right and radical left wing parties. Although these two party families differ in terms of origins, transnational links and policy and although nationalism is usually associated with parties of the right in the literature, this paper argues that in fact nationalism cuts across party lines and is associated with both party families’ opposition to European integration. In order to test our argument, we employ a mixed methods approach. First, we use a new dataset from the 2009 Euromanifestos Project (EMP), which coded party manifestos. We have isolated questions that refer to nationalism and European integration and examine broad policy parallels between the two party families across Europe. Second, we apply the findings from the quantitative analysis on Greece and France as two countries with a strong presence of both radical right and radical left small parties.

Induction machine stray loss from inter-bar currents

Stray load loss refers generally to the sources of induction machine loss not accounted for by typical calculations of primary or secondary copper loss, no load core loss, or friction and windage loss. Harmonic rotor bar currents from the non-sinusoidal distribution of the slotted stator winding contribute significant stray load loss. Rotor bars, especially on cast rotors for machines under fifty horsepower (37.3 kW), can be skewed, helically twisted from one end to the other, to reduce loss, torque, and noise from alignment of rotor and stator slots and from harmonic rotor currents. Interbar currents flowing circumferentially through the laminations between skewed and non-insulated rotor bars can significantly increase stray load loss. Presented equations adjust the effective rotor resistance and skew factor of the extended per-phase induction machine equivalent circuit model in order to account for the impact of inter-bar currents. The average value of resistance between neighboring rotor bars significantly impacts calculations of rotor bar and inter-bar current and loss and has been determined for a number of measured rotors. Rotors fit into one of two distinct categories where either the bar-to-lamination contact resistance dominates the inter-bar resistance or the total resistance divides more equally between values of bar, lamination, and contact resistance. Performance calculations using the adjusted equivalent circuit model are verified theoretically against previous calculation methods and experimentally by comparison to measured test results including variations in rotor skew, conductor conductivity, and inter-bar resistance. A number of different cast copper and aluminum five and ten horsepower test induction motors performed differently than originally predicted and variably between nominally identical machines. Inter-bar currents are part of the cause of both the variation and additional losses measured on these machines. The adjusted equivalent circuit equations improve estimations of motor performance and allow identification of means to increase machine efficiency by minimizing the stray load loss due to inter-bar currents.

Improving quality of training data for learning to rank using click-through data

In information retrieval, relevance of documents with respect to queries is usually judged by humans, and used in evaluation and/or learning of ranking functions. Previous work has shown that certain level of noise in relevance judgments has little effect on evaluation, especially for comparison purposes. Recently learning to rank has become one of the major means to create ranking models in which the models are automatically learned from the data derived from a large number of relevance judgments. As far as we know, there was no previous work about quality of training data for learning to rank, and this paper tries to study the issue. Specifically, we address three problems. Firstly, we show that the quality of training data labeled by humans has critical impact on the performance of learning to rank algorithms. Secondly, we propose detecting relevance judgment errors using click-through data accumulated at a search engine. Two discriminative models, referred to as sequential dependency model and full dependency model, are proposed to make the detection. Both models consider the conditional dependency of relevance labels and thus are more powerful than the conditionally independent model previously proposed for other tasks. Finally, we verify that using training data in which the errors are detected and corrected by our method, we can improve the performance of learning to rank algorithms.
Dynamic bacterial genome organization

Recently completed projects of sequencing chromosomal fragments and entire chromosomes, as well as physical mapping of genomes, have opened novel inroads to the understanding of the biology of bacterial genomes. From these studies one may draw some conclusions. (i) The organization of orthologous genes on the bacterial chromosome is not conserved during evolution. (ii) The bacterial genome is more complex and also more flexible than hitherto thought. Genetic elements are sometimes part of the chromosome, while at other times they are independent elements or parts of alternative replicons (e.g. large plasmids). Such replicons, carrying essential genes, now seem to deserve the designation ‘secondary chromosomes’. A study of the regulation of replication and segregation of these essential genetic elements will be of great interest.
Disciplinary Power, the Oligopticon and Rhizomatic Surveillance in Elite Sports Academies

This article aims to apply a post-panoptic view of surveillance within the context of elite sport. Latour’s (2005) ‘oligopticon’ and Deleuze and Guttari’s (2003) ‘rhizomatic’ notion of surveillance networks are adopted to question the relevance and significance of Foucault’s (1979) conceptualisation of surveillance within an elite sports academy setting. A contemporary representation of bio-politics (Rose 1999, 2001) is further utilised to discern the mode of governance and control effective within such institutions. In so doing, this article seeks to understand the evolving methods of surveillance technology and governance and how they are situated within the setting of a contemporary institution. Such considerations aim to provoke a line of questioning surrounding the normalisation of intrusive surveillance practices and their impact upon identity construction and an authentic sense of self.

Caveat Lector: Sample Selection in Historical Heights and the Interpretation of Early Industrializing Economies

Much of the research on height in historical populations relies on convenience samples. A crucial question with convenience samples is whether the sample accurately reflects the characteristics of the population; if not, then estimated parameters will be affected by sample selection bias. This paper applies a simple test for selection biased developed in Bodenhorn, Guinnane, and Mroz (2013) to several historical samples of prisoners, freed slaves, and college students. We reject the hypothesis of no selection bias in all cases. Using Roy's (1951) model of occupational choice, we interpret these findings as reflecting the economic forces that lead individuals to take the actions the led to inclusion in the sample. Our findings suggest that much of the evidence on the "industrialization puzzle" during the nineteenth century could reflect changing selection into the samples rather than changes in population heights.
Education Model "Bandongan" for Farmers Society of Agricultural Skills Training in the Background of Sosioculture "Pesantren" in East Java *

This study aims to describe and understand the implementation of skills training Model "Bandongan" for the peasant society in the background of sociocultural "pesantren" in East Java. "Bandongan" is a pattern of skills training with a group approach typical "pesantren" which resulted in humans as a whole. "Pesantren" is "Islamic boarding school". Thus, social change in rural farming communities sociocultural background "pesantren" always nuanced relegius. The study used qualitative research methods with a knife phenomenological analysis, to understand the actions of individuals based "because motives" and "in order to motives". The results showed that the actions of individual actors indigeniuos education model "bandongan" in a social change in the village-based "pesantren" is different. Meaning the actions of coaches influenced by the understanding of the Holy Quran, Al-Hadith, and the "yellow book", idol, the character of institutions, and traditions. Meaning action peasant society based on: (1) religious social rationality of the economic rationality, (2) the rationality of faith and piety to God almighty one, (3) the rationality of justice for society and religious life. The findings are in contrast to the thesis Geertz. Geertz view ignores the existence of the influence of the holy book, idol, character and local tradition. In these research findings, it has proven to give "orders" against one's actions. DOI: 10.5901/mjss.2015. v6n5p515
The Impact of Noise on Switching Rate of L-Fold Selection Diversity

Switching transients generated by a selection diversity combiner corrupt receiver filters and increase the system outage as well as corrupting channel estimation. In order to produce an accurate (transient-free) channel estimate and reduce the internal outage, one prefers small switching rates. Therefore, knowledge of the switching rate provides useful information for system engineers in the design of selection diversity receivers. Yet, few results regarding the switching rates of select diversity receivers operating in noisy fading channels have been published. The switching rate of L-fold selection diversity combining in a noisy environment is studied. A closed-form expression for the switching rate is derived for independent and identically distributed (i.i.d.) Rayleigh fading channels in the presence of noise using order statistics. Simulation results are also provided to validate the theoretical results. Our results show that in order to produce an accurate channel estimate and reduce the internal outage, one prefers small switching rates, which can be realized by employing adaptive receiver filters to avoid excessive deleterious switching transients.
System-level assessment of volumetric 3D vehicular MIMO antenna based on measurement

This paper presents the evaluation of a volumetric 3D multi-element antenna for vehicular connectivity based on a system-level approach. First, the antenna design to be used in Long Term Evolution (LTE) networks and its realization based on molded interconnect device (MID) technology are shown. During the antenna evaluation, system-level key performance indicators (KPI) like condition number and channel capacity are investigated and are compared to indicators like return loss, inter-element coupling and radiation characteristics. System-level KPI include effects due to vehicular antenna integration or channel conditions, which have an impact on the overall performance. A suitable 2D reference antenna arrangement is developed to evaluate the performance gain of the volumetric antenna design approach by performing test drives in a live LTE network.
Mission, Initiatives, and Obstacles to Research in Agricultural Education: A National Delphi Using External Decision-Makers.

“Progress during the past years in the technological and methodological aspects of research (in agricultural education) has not been accompanied by comparable improvements in another very important aspect of research, namely, the relevance, significance, and importance of problems and issues that we investigate . I propose that our highest priority for continuing progress in research in agricultural education must be that we pay greater attention to the significance and importance of the problems and issues that we research” (Warmbrod, 1986, p. 9). Similar concerns regarding issues, focus, and programmatic efforts have been expressed by Krebs (1976), Mannebach (1980), Moore (1987), Stewart, Shinn, and Richardson (1977), and Vaughn (1983).
Use and Abuse of the Internet: Parental Knowledge of Cyber Bullying in Middle School

The current literature has emphasized the impact of cyber bullying on the lives of children and adolescents. However there are gaps in the literature in terms of when and how, parents and school officials should intervene and prevent future occurrences. The purpose of this study was to provide a foundational basis for research associated with middle school children‘s use and abuse of the Internet, specifically online aggression and violence, termed as cyber bullying. Parental knowledge of student‘s Internet use and the prevalence of cyber bullying were investigated. Caregivers with students enrolled in 6 th , 7 th and 8 th grade in a suburban school of culturally diverse and varied socioeconomic status were studied. This research identified key elements to address the possible need for prevention strategies targeting students, parents and educators. Results demonstrated that parental perceptions of children‘s Internet experience and children‘s actual Internet use are in some cases shown to be different.
Amenable groups with a locally invariant order are locally indicable

We show that every amenable group with a locally invariant partial order has a left-invariant total order (and is therefore locally indicable). We also show that if a group G admits a left-invariant total order, and H is a locally nilpotent subgroup of G, then a left-invariant total order on G can be chosen so that its restriction to H is both left-invariant and right-invariant. Both results follow from recurrence properties of the action of G on its binary relations.
MY JOB IS MY CASTLE: IDENTIFICATION IN ORGANIZATIONAL CONTEXTS

Due to growing globalization, cross-national alliances, (international) organizational mergers, restructuring, delayering, or outsourcing, one could assume that the psychological bond between employee and employing organization has become weaker. Also, new forms of work and enterprises like telecommuting or other types of virtual organizations should psychologically distract employees even more from their organizations. One could also argue, however, that some kind of psychological attachment between organization and organizational member is more important for both the individual’s well-being and the organization’s success because of these rapid changes. The present overview of organizational identification argues in exactly this direction and holds some empirical evidence for this (e.g., Wiesenfeld, Raghuram, & Garud, 2001). The aim of this chapter is to give an overview of the antecedents, elements, and consequences of social identification in organizational contexts and thus the relevance of the concept for the analysis of organizational behavior. This will be done particularly in two domains where change processes are going on steadily and increasingly— organizational mergers and group productivity.
