Bat Algorithm a nd Firefly Algorithm f or Improving Dynamic Stability o f Power Systems Using UPFC

In this paper a hybrid method for improving the dynamic stability of the power system using UPFC is proposed. The novelty of the proposed method is combined performance of the Bat-inspired algorithm and Firefly Algorithm (FA), which provides improved searching ability, automatic subdivision and random reduction. Here, the bat-inspired algorithm optimizes the maximum power loss bus while the generator fault occurs, which inturn affects the power flow constraints like voltage, power loss, real and reactive power. For improving the dynamic performance, the optimum capacity of UPFC has been determined with minimum cost by using the FA algorithm. The attained capacity UPFC has been located in the affected location and analyzes the power flow of the system. The proposed method is implemented in the MATLAB/simulink platform with IEEE 30 and IEEE 14 standard bench mark system. The proposed method performance is evaluated by comparison with different techniques like hybridized Gravitational Search Algorithm (GSA) and Bat algorithm. The comparison results proved the effectiveness of the proposed method and confirm its potential to solve the problem.
A study of electromagnetic field generated by high voltage lines using COMSOL MULTIPHYSICS

Possible harmful effect of the low frequency electric and magnetic field on human health. This paper investigates using the COMSOL MULTIPHYSICS software modules in calculating the electromagnetic fields generated in the vicinity of High Voltage (HV) power transmission lines. The presented results in this paper demonstrate the effectiveness of using the electrostatic and magneto static modules of the COMSOL MULTIPHYSICS in electromagnetic fields calculation at many levels near power transmission lines. The resulting fields are compared with the International Commission on Non Ionizing Radiation Protection (ICNIRP) field guidelines.
Joint Uplink Base Station Association and Power Control for Small-Cell Networks With Non-Orthogonal Multiple Access

Since non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC) can achieve superior spectral-efficiency and energy-efficiency, the concept of SCN using NOMA with SIC is proposed in this paper. Due to the difference in small-cell base stations’ locations, each mobile user perceives different channel gains to different small-cell base stations. Therefore, it is important to associate a mobile user with the right base station and control its transmit power for the uplink SCN using NOMA with SIC. However, the already-challenging base station association problem is further complicated by the need of transmit power control, which is an essential component to manage co-channel interference. Despite its importance, the joint base station association and power control optimization problem that maximizes the system-wide utility and at the same time minimizes the total transmit power consumption for the maximum utility has remained largely unsolved for the uplink SCN using NOMA with SIC, mainly due to its non-convex and combinatorial nature. To solve this problem, we first present a formulation transformation that captures two interactive objectives simultaneously. Then, we propose a novel algorithm to solve the equivalently transformed optimization problem based on the coalition formation game theory and the primal decomposition theory in the framework of simulated annealing. Finally, theoretical analysis and simulation results are provided to demonstrate that the proposed algorithm is guaranteed to converge to the global optimal solution in polynomial time.
HEALTH LOCUS OF CONTROL AND CHRONIC DISEASE: AN EXTERNAL ORIENTATION MAY BE ADVANTAGEOUS

A total of 62 cancer chemotherapy patients completed the Multidimensional Health Locus of Control (MHLC) scale prior to receiving training in progressive muscle relaxation and/or biofeedback for the reduction of the side effects of their treatment. Physiological measures of arousal and patient-reported indices of negative affect and nausea were collected during baseline, training, and follow-up chemotherapy sessions. Results indicated that following relaxation training and/or biofeedback, chemotherapy patients with a high external health locus of control orientation, as compared to patients without such an orientation, had lower levels of physiological arousal and reported less negative affect. These findings suggest that in medical situations in which little personal control is possible, an external health locus of control may be advantageous.
Ripley: automatically securing web 2.0 applications through replicated execution

Rich Internet applications are becoming increasingly distributed, as demonstrated by the popularity of AJAX or Web 2.0 applications such as Facebook, Google Maps, Hotmail and many others. A typical multi-tier AJAX application consists, at least, of a server-side component implemented in Java J2EE, PHP or ASP.NET and a client-side component running JavaScript. The resulting application is more responsive because computation has moved closer to the client, avoiding unnecessary network round trips for frequent user actions. However, once a portion of the code has moved to the client, a malicious user can subvert the client side of the computation, jeopardizing the integrity of the server-side state. In this paper we propose Ripley, a system that uses replicated execution to automatically preserve the integrity of a distributed computation. Ripley replicates a copy of the client-side computation on the trusted server tier. Every client-side event is transferred to the replica of the client for execution. Ripley observes results of the computation, both as computed on the client-side and on the server side using the replica of the client-side code. Any discrepancy is flagged as a potential violation of computational integrity. We built Ripley on top of Volta, a distributing compiler that translates . NET applications into JavaScript, effectively providing a measure of security by construction for Volta applications. We have evaluated the Ripley approach on 5 representative AJAX applications built in Volta and also Hotmail, a large widely-used AJAX application. Our results so far suggest that Ripley provides a promising strategy for building secure distributed web applications, which places minimal burden on the application developer at the cost of a low performance overhead.
Goal Modification, Learning Styles, and Achievement in Mathematics

This study investigated whether mastery and competitive goals could be developed among students, while controlling for the possible effects of student learning styles. A pretest-posttest control group design was used in this 10-week experiment that employed three intact high school mathematics classes. Results showed that mastery and competitive goals could be separately modified among students. However, learning styles did not moderate the effects of these goal modifications. The study further investigated which of the three goals – mastery, competitive, and avoidance – predicts achievement in mathematics. The outcome showed that each of the three goals linearly predicts mathematics achievement. However, when the effects of all three goals were simultaneously considered, only avoidance goals remained as a predictor of achievement. It is recommended that further investigations be made on the possible classification of avoidance goals into projective, compliance, and work-avoidance goals. Moreover, the positive potential of projective goals should be explored.
Gender, age and tenure as moderators of work-related stressors' relationships with job performance: A meta-analysis

We investigated the extent to which three socio-demographic variables, employee gender, age, and tenure, moderated the meta-correlations of role conflict and role ambiguity with job performance. To test these moderating effects, we quantitatively synthesized 30 independent studies (total N = 7700). No moderating effects were found for gender and tenure. Controlling for employee tenure and gender, we found that employee mean age had a moderating effect on the role ambiguity-performance correlation, with negative correlations tending to decrease with increasing age. Moreover, two significant two-way interactions were found between the moderators. As the percentage of women in the studies and the respondents' mean age simultaneously increased, and as the mean sample tenure and age of the respondents in the studies simultaneously increased, there was a reduction in the negative relationship between role ambiguity and performance. The implications of these results for future research are discussed.
Reducing the rates of prescribing high-dose antipsychotics and polypharmacy on psychiatric inpatient and intensive care units: results of a 6-year quality improvement programme

Background: There is no conclusive evidence that either high doses or combinations of antipsychotics are more effective than standard doses or monotherapy alone. Nonetheless, prescription of both remains prevalent in the UK. In 2006 the South London and Maudsley NHS Foundation Trust (SLAM) participated in a national survey of prescription of antipsychotic medications, organized by the Prescribing Observatory for Mental Health. Over half of the patients on SLAM inpatient or psychiatric intensive care units were prescribed a high-dose antipsychotic or a combination of antipsychotics. Prescribing high-dose antipsychotics and polypharmacy in SLAM was found to be among the highest in the UK. Aim: To assess the impact of a 6-year quality improvement programme aimed at reducing the rates of prescribing high-dose antipsychotics and polypharmacy on SLAM inpatients and psychiatric intensive care units. Results: There was a significant reduction between baseline and final survey in the rates of prescription of both high-dose antipsychotics and polypharmacy on SLAM inpatients and intensive care units (58% versus 10% p < 0.0001 and 57% versus 16%, p < 0.0001 respectively). The proportion of patients at final survey prescribed a high-dose antipsychotic and a combination was substantially lower in SLAM than in the national sample (10% versus 28%, p < 0.0001 and 16% versus 38%, p < 0.0001 respectively). Clinical implications: A sustained change in the prescribing culture of an organization can be achieved through a targeted improvement programme.
Distant-talking continuous speech recognition based on a novel reverberation model in the feature domain

A novel approach for automatic speech recognition in highly re-verberant environments, proposed in [1] for isolated word recognition, is extended to continuous speech recognition (CSR) in this paper. The approach is based on a combined acoustic model consisting of a network of clean speech HMMs and a reverberation model. Because the grammatical information and the information about the acoustic environment are strictly separated in the combined model, a high degree of ﬂexibility for adapting the system to new tasks and new environments is attained. We show that virtually all known CSR search algorithms can be used for decoding the proposed combined model if a few extensions are added. In a simulation of a connected digit recognition task, the proposed method achieves more than 40 % reduction of the word error rate compared to a conventional HMM-based system trained on rever-berant speech, at the cost of an increased decoding complexity.
Design techniques for a 1-V operation Bluetooth RF transceiver

This paper describes circuit techniques for a 1-V operation Bluetooth PF transceiver in 0.2-/spl mu/m CMOS/SOI. Folded LC-tuned and folded transistor-current-source circuits achieve 1-V operation of the RF transceiver. Tuning circuits and a bias generation circuit for robust transceiver operation are explained.
A field trial of a collaborative online scenario creation system for emergency management

In Emergency Management and Business Continuity Planning, scenarios are a widely used tool. Existing scenario creation systems allow distributed groups to create scenarios together but have limited collaboration support. This study developed and evaluated a solution to provide various types of collaboration support around a knowledge structure at the core of a collaborative scenario creation system called Collario. Following the Design Science paradigm, it evolved through four iterations into a working prototype. Several evaluation methods, including protocol analysis and field study, were employed to evaluate the design effects and obtain user feedback. The results of the first field trial are described in this paper. They indicate that the system is useful to support creation and discussion of emergency scenarios in virtual teams and to share knowledge and experiences among geographically distributed emergency professionals and researchers. It was also found that the system is not hard to learn and use.
Beyond the Gatekeepers

This study used intensive interview and survey data from 62 municipal court professionals (judges, prosecutors, and public defenders) to expand on the limited research on the court processing of domestic violence cases. The participants reported legal variables as both what should be and what were actually most commonly used in domestic violence court decisions. Victim testimony was also reported as important, and these data suggest that domestic violence victims cooperate with the courts more often than is believed. Victim advocate and batterer intervention workers' opinions were reported as both what should be and were least influential in the case outcome. Finally, the respondents rated the case sentences as having very little impact on domestic violence recidivism.
The influence of central administration of dopaminergic and cholinergic agents on morphine-induced amnesia in morphine-sensitized mice

In the present study, effects of intracerebroventricular (i.c.v.) injections of dopaminergic and cholinergic agents on morphine-induced amnesia in morphine-sensitized mice were investigated by using a one-trial passive avoidance task. Amnesia induced by pre-training morphine was significantly reversed in morphine-sensitized mice, which had previously received once daily injections of morphine (20 and 30mg/kg, s.c.) for 3 days. Three daily injections of SKF 38393 (1, 2 and 4 g/mouse, i.c.v.) or SCH 23390 (0.25, 0.5, 0.75 and 1 g/mouse, i.c.v.) before morphine, and during morphine-sensitization, decreased and increased the amnesia induced by pre-training morphine respectively. Three daily injections of quinpirole (0.3, 1 and 3 g/mouse, i.c.v.) or sulpiride (0.03, 0.1, 0.3 and 1 g/mouse, i.c.v.) before morphine, also decreased and increased the amnesia induced by pre-training morphine respectively. Morphine-sensitized mice received similar injections of cholinergic agents. Three daily injections of physostigmine (1, 3 and 5 g/mouse, i.c.v.) or atropine (1, 4 and 7 g/mouse, i.c.v.) before morphine, and during morphine-sensitization, decreased and increased the amnesia induced by pre-training morphine respectively. Three daily injections of nicotine (0.75, 1 and 2 g/mouse, i.c.v.) or mecamylamine (1, 3 and 6 g/mouse, i.c.v.) before morphine, also decreased and increased the amnesia induced by pre-training morphine respectively. The results suggest that morphine sensitization affects the impairment of memory formation and thus it is postulated that central dopaminergic and cholinergic systems may play an important role in this effect.
Characterization of the 9.5-kDa ubiquinone-binding protein of NADH:ubiquinone oxidoreductase (complex I) from Neurospora crassa.

A small polypeptide subunit of the NADH:ubiquinone reductase (complex I) from Neurospora crassa has been identified by photoaffinity labeling to participate in the binding of ubiquinone [Heinrich, H. , & Werner, S. (1992) Biochemistry (preceding paper in this issue)]. This polypeptide is further characterized by its primary structure and by an assessment of its localization within complex I. A lambda gt11 cDNA expression library was screened using a specific antibody directed against this individual subunit of complex I. Two groups of clones, coding for polypeptide subunits of the appropriate apparent molecular weight, were isolated. One group was shown to contain the relevant recombinants. The derived amino acid sequence for the 9.5-kDa ubiquinone-binding polypeptide shows a similarity with a putative ubiquinol-binding subunit (also a 9.5-kDa polypeptide) from complex III of bovine heart [Usui, S. , Yu, L. , & Tu, C. -A. (1990) Biochemistry 29, 4618-4626]. The polypeptide has a hydrophobic stretch of a sufficient length to span the membrane. It resists against extraction with NaBr or Na2CO3, and therefore probably is buried in the so-called hydrophobic membrane portion of complex I. This nuclearly-encoded subunit lacks a typical cleavable presequence and is imported into isolated mitochondria by a membrane potential-dependent process.
Efficient computation of the discrete Wigner distribution function through a new iterative algorithm

This paper presents a new iterative method to speed up the DWDF computation. At present it has been considered from a computational point of view as a 1-D section of the Wigner kernel (WK)N point FTs. We purpose a new way to compute the DWDF based on the symmetry properties of the WK and the cosine function. The proposed algorithm is based on a subdivision procedure: on the one hand we have subdivided for each m-value the sum over the k variable into log/sub 2/N/4-PL partial sums, where PL is the k parity level; and on the other hand for each n-value the algorithm computes the DWDF elements by grouping it depending on the m PL. The algorithm has been optimized to reduce the accesses of memory, and it improves the FFT algorithms when the number of samples is less than 256 and for this number the algorithm matches the FFT algorithms.
Assessing elementary school children's Social skills : Evaluation of the parent Version of the Matson evaluation of Social Skills with Youngsters

This study examined J. L. Matson's (1990) assertion that the Teacher Version of the Matson Evaluation of Social Skills with Youngsters (MESSY) can also be used with parents. Parents and teachers of 179 children completed the MESSY. Parent- and teacher-completed MESSYs were compared on factor structure, score convergence, and relationship to conceptually relevant cognitive and behavioral variables. Additionally, the factor structure and correlates of the parent-teacher composite scores were examined. Results suggested that the parent-reported MESSY does not show a particularly stable factor structure and is not highly related to teacher reports. However, the composite score, which integrated parent and teacher reports, may be a reasonable means of involving parents in reports of children's social skills.
Protease-activated Receptor-2 Increases Exocytosis via Multiple Signal Transduction Pathways in Pancreatic Duct Epithelial Cells*

Protease-activated receptor-2 (PAR-2) is activated when trypsin cleaves its NH2 terminus to expose a tethered ligand. We previously demonstrated that PAR-2 activates ion channels in pancreatic duct epithelial cells (PDEC). Using real-time optical fluorescent probes, cyan fluorescence protein-Epac1-yellow fluorescence protein for cAMP, PHPLC-δ1-enhanced green fluorescent protein for phosphatidylinositol 4,5-bisphosphate, and protein kinase Cγ (PKCγ)-C1-yellow fluorescence protein for diacylglycerol, we now define the signaling pathways mediating PAR-2 effect in dog PDEC. Although PAR-2 activation does not stimulate a cAMP increase, it induces phospholipase C to hydrolyze phosphatidylinositol 4,5-bisphosphate into inositol 1,4,5-trisphosphate and diacylglycerol. Intracellular Ca2+ mobilization from inositol 1,4,5-trisphosphate-sensitive Ca2+ stores and a subsequent Ca2+ influx through store-operated Ca2+ channels cause a biphasic increase in intracellular Ca2+ concentration ([Ca2+]i), measured with Indo-1 dye. Single-cell amperometry demonstrated that this increase in [Ca2+]i in turn causes a biphasic increase in exocytosis. A protein kinase assay revealed that trypsin also activates PKC isozymes to stimulate additional exocytosis. Paralleling the increased exocytosis, mucin secretion from PDEC was also induced by trypsin or the PAR-2 activating peptide. Consistent with the serosal localization of PAR-2, 1 μm luminal trypsin did not induce exocytosis in polarized PDEC monolayers; on the other hand, 10 μm trypsin at 37 °C damaged the epithelial barrier sufficiently so that it could reach and activate the serosal PAR-2 to stimulate exocytosis. Thus, in PDEC, PAR-2 activation increases [Ca2+]i and activates PKC to stimulate exocytosis and mucin secretion. These functions may mediate the reported protective role of PAR-2 in different models of pancreatitis.
Understanding the Developing Role of Global Health Partnerships on Access to Medication: An STS Perspective

A conceptual framework for studying the role of global health partnerships (GHPs) in determining policy practices on access to medication is presented. Although GHPs are of a practical nature, they are implicitly theory informed. The narratives used by GHP partners in relating to access to medication have theoretical origins. Building on the theoretical literature on models and the notion of embodied knowledge found in science and technology studies, GHPs are conceptualized as models that mediate between theory and practice. The proposed framework can be used to investigate the role of theory in the creation of GHP models and how the models shape global and national policy practices. A social constructivist approach is suggested as a suitable method for empirical analysis.
The Hand Performance Test with a Modified Time Limit Instruction Enables the Examination of Hand Performance Asymmetries in Adults

Asymmetry of hand performance was investigated with the paper-and-pencil test of hand dominance originally developed by Steingruber in 1971. This test, originally constructed to measure asymmetry of hand performance in children, gave appropriate scores on asymmetry of hand performance in adults if a shorter time limit than originally proposed was applied. Asymmetry of hand performance in adults as measured with the new instruction showed reliable asymmetries in performance which are similar to those obtained on different widely accepted tests measuring asymmetries of hand performance.
