Determining losses of motors designed for converter operation

There exist no generally accepted methods to determine the losses and efficiency of motors designed for converter operation. There exist two alternative methods that are applicable to all motor technologies - the input-output method and the calorimetric method. In this paper, the both methods are used to determinate the losses of the standard 37 kW squirrel cage induction motor. The results obtained with these methods are further analyzed and the uncertainty of the methods are discussed.
Influencing household location decision making: Potential in transportation management?

Housing location decision is basic information for transportation modeling. As the basis of trip generation its modelling is quite well-studied. These models are based on economic theories and assume the knowledge of a broad range of decisive information. At the same time people tend to make decision knowing far less information using heuristics. Utilizing this decision making process the question arises: providing more detailed, easily accessible information do people make more rational decision? And further considering: providing these information could we influence decision making to match with the objectives of regional development and transportation management?
A Functional Magnetic Resonance Imaging Study of the Effects of Low Frequency Right Prefrontal Transcranial Magnetic Stimulation in Depression

The study aimed to explore the biological effects of low-frequency repetitive transcranial magnetic stimulation (LFR-TMS) treatment applied to the right prefrontal cortex, comparing this with the effects of high-frequency left-sided (HFL-TMS) in patients with treatment-resistant depression. Twenty-six patients with treatment-resistant depression were randomized to receive either daily LFR-TMS or HFL-TMS treatment for 3 weeks and underwent functional magnetic resonance imaging during a planning task before and after treatment. Patients responded clinically to both forms of treatment with no difference in the degree of response (F1,24 = 0.65;P > 0.05). Low-frequency repetitive transcranial magnetic stimulation resulted in no overall change in task-related activation. However, responders to LFR-TMS demonstrated a bilateral decrease in activity in middle frontal gyrus. In contrast, HFL-TMS produced an increase in activation in left precuneus with responders showing increased activation in several additional regions. Response to LFR-TMS is associated with a bilateral reduction in frontal activation that does not seem to be a nonspecific effect of treatment and differs from the response to HFL-TMS.
Multidimensional Commitment of Intercollegiate Student-Athletes: Its Effects on Intention to Leave and Satisfaction

Abstract Given the importance and relative financial investments institutions formulate regarding student-athletes, intercollegiate coaches and administrators must make strategic decisions in recruiting and retaining them. A lack of student-athlete persistence is detrimental to individual teams and athletic departments as a whole; thus, every effort needs to be made to retain these individuals. Furthermore, Riemer and Chelladurai (1998) argue that the success of an intercollegiate athletic department should be, at least to some degree, based on the satisfaction of its student-athletes. An important first step in this regard is to understand the dynamics of student-athletes' continued participation with (or intention to leave) their institution and their satisfaction. Based on Meyer and Allen's (1991) multidimensional conceptualization of commitment (i.e., affective, normative, and continuance commitment), the purpose of this study was to (a) assess student-athlete commitment, (b) apply the multidimensional conceptualization of commitment to three relevant foci (i.e., coach, institution, and team), and (c) relate these components of student-athlete commitment to the student-athletes' intention to leave their current university and satisfaction (with their coach, with their university, and with their team). In addition, differences in levels of commitment were examined based on gender, rank (i.e., upper- vs. under-classmen), and playing status on the team (i.e., starter vs. non-starter). Student-athletes from 11 team sports from a large, Division I-A, Midwestern university were selected to participate in this study (n = 190). Results of the study showed female student-athletes were significantly higher in their levels of commitment to their university and team, while male student-athletes were significantly higher in their affective commitment to their head coach. With regard to playing status, starters were significantly higher in their commitment to their coach.Commitment was significantly related to intention to leave for all three foci examined. Of the three, commitment to team explained the most variance (17.5%) in intention to leave. All three foci of commitment were also significantly related to satisfaction, with commitment to coach explaining the most variance (68.6%). Possible explanations for these findings, along with directions for future research on student-athlete commitment will be discussed.
A fast online full parameter estimation of a PMSM with sinusoidal signal injection

In this paper, a fast online parameter estimation scheme with sinusoidal d-axis current injection is introduced. Compared to the existing parameter estimation strategies, the proposed estimation scheme has relative faster convergence time and is feasible in the transient operation. This estimation scheme is realized by the recursive least square algorithm based on different operating points of the Permanent Magnet Synchronous Machine (PMSM). With the proposed estimation scheme, the four parameters of the PMSM can be simultaneously estimated online. The derivatives of the d- and q-axis currents are considered in the proposed estimation scheme so that it is feasible in both steady state and transient state operation. The sampling principle is discussed to avoid the rank deficient problem for the estimation. An averaged sliding window is introduced for the estimation to minimize the estimation error from the A/D conversion and to reduce the influence of the measurement noise. The proposed estimation scheme is validated by the experimental results and compared with the parameter estimation with square wave current injection.
Prevention of Pediatric Medication Errors by Hospital Pharmacists and the Potential Benefit of Computerized Physician Order Entry

OBJECTIVES. The purpose of this work was to characterize medication errors and adverse drug events intercepted by a system of pediatric clinical pharmacists and to determine whether the addition of a computerized physician order entry system would improve medication safety. METHODS. The study included 16938 medication orders for 678 admissions to the pediatric units of a large academic community hospital. Pediatric clinical pharmacists reviewed medication orders and monitored subsequent medication use. Medication errors and adverse drug events were identified by daily review of documentation, voluntary reporting, and solicitation. Each potentially harmful medication error was judged whether or not it was intercepted and, if not, whether it would have been captured by a computerized physician order entry system. RESULTS. Overall, 865 medication errors occurred, corresponding with a rate of 5.2 per 100 medication orders. A near-miss rate of 0.96% and a preventable adverse drug event rate of 0.09% were observed. Overall, 78% of potentially harmful prescribing errors were intercepted; however, none of the potentially harmful errors occurring at administration was intercepted and accounted for 50% of preventable adverse drug events. A computerized physician order entry system could capture additional potentially harmful prescribing and transcription errors (54%–73%) but not administration errors (0% vs 6%). CONCLUSIONS. A system of pediatric clinical pharmacists effectively intercepted inpatient prescribing errors but did not capture potentially harmful medication administration errors. The addition of a computerized physician order entry system to pharmacists is unlikely to prevent administration errors, which pose the highest risk of patient injury.
Language-in-Education Policy and Planning

This chapter provides a descriptive review of research on language-ineducation policy and planning. We intend no theoretical generalizations but rather a descriptive summary of present research (1990–1993). With various interpretations of language-in-education policy available in the literature, it is first necessary to establish the perspective which guides this review. Ingram (1990), for example, confines language-in-education to second or foreign language teaching and learning although he mentions literacy and bilingual education as topics in language-in-education.
Upregulated Expression of C-X-C Chemokine Receptor 4 Is an Independent Prognostic Predictor for Patients with Gastric Cancer

Aberrant chemokine (C-X-C motif) receptor CXCR4 expressions in malignant tissues have been reported, but its role in gastric cancer prognosis remains unknown. Our studies were designed to investigate the expression and prognostic significance of CXCR4 in patients with gastric cancer. CXCR4 expression was retrospectively analyzed by immunohistochemistry in 97 patients with gastric adenocarcinoma from China. Results were assessed for association with clinical features and overall survival by using Kaplan-Meier analysis. Prognostic values of CXCR4 expression and clinical outcomes were evaluated by Cox regression analysis. A molecular prognostic stratification scheme incorporating CXCR4 expression was determined by using receiver operating characteristic (ROC) analysis. The results show that CXCR4 predominantly localized in the cell membranes and cytoplasm. The protein level of CXCR4 was upregulation in gastric cancer tissues and upregulated expression of CXCR4 was only significantly associated with Lauren classification (P<0.001). Increased CXCR4 expression in gastric cancer tissues was positively correlated with poor overall survival of gastric cancer patients (P<0.001). Further multivariate Cox regression analysis suggested that intratumoral CXCR4 expression was an independent prognostic indicator for the disease. Applying the prognostic value of intratumoral CXCR4 density to TNM stage system showed a better prognostic value in patients with gastric cancer. In conclusion, intratumoral CXCR4 expression was recognized as an independent prognostic marker for the overall survival of patients with gastric cancer. On the basis of TNM stage, detection of CXCR4 expression will be helpful for predicting prognosis for patients with gastric cancer.
Home From Home? A Mixed-Methods Study of Relocation Within a Purpose-Built Retirement Community

Moving from a location where one has intimate knowledge of the physical and social aspects of space, with established daily routines, social networks, and attachment to place, can present challenges in later life. The literature supports the optimality of aging in place, and several studies point to the potentially detrimental effects of disruption, particularly in cases of involuntary relocation. Using both qualitative and quantitative data, this exploratory study aimed to examine the experiences and effects of relocation as part of a redevelopment of a community housing older people. Thirty-five interviews were completed with 17 participants across stages of the relocation process. Quantitative indicators of well-being were also compared between residents who had moved and those who had not over this period. No significant differences were found between movers and non-movers in the quantitative data. However, the qualitative data suggested that the relationship with the environment is more nuanced than the duality of optimal and detrimental. Individuals’ agency in relation to their environment was found to be mediated by such factors as lifestyle and daily routine, bereavement, sociospatial factors, and access to nature. The effects of relocation appear to be complex and mediated by a variety of individual and social factors.
What’s Next: Recruitment of a Grounded Predictive Body Model for Planning a Robot’s Actions

Even comparatively simple, reactive systems are able to control complex motor tasks, such as hexapod walking on unpredictable substrate. The capability of such a controller can be improved by introducing internal models of the body and of parts of the environment. Such internal models can be applied as inverse models, as forward models or to solve the problem of sensor fusion. Usually, separate models are used for these functions. Furthermore, separate models are used to solve different tasks. Here we concentrate on internal models of the body as the brain considers its own body the most important part of the world. The model proposed is formed by a recurrent neural network with the property of pattern completion. The model shows a hierarchical structure but nonetheless comprises a holistic system. One and the same model can be used as a forward model, as an inverse model, for sensor fusion, and, with a simple expansion, as a model to internally simulate (new) behaviors to be used for prediction. The model embraces the geometrical constraints of a complex body with many redundant degrees of freedom, and allows finding geometrically possible solutions. To control behavior such as walking, climbing, or reaching, this body model is complemented by a number of simple reactive procedures together forming a procedural memory. In this article, we illustrate the functioning of this network. To this end we present examples for solutions of the forward function and the inverse function, and explain how the complete network might be used for predictive purposes. The model is assumed to be “innate,” so learning the parameters of the model is not (yet) considered.
Forced-Choice Applied to College Faculty Rating

THIs article is concerned with a rating scale devised to measure student opinion of faculty members as teachers. No argument will be presented for or against student ratings as means of evaluation of faculty. Implicit, of course, in the fact that time and energy were expended to construct a scale, is the assumption that student opinion, as accurately measured as possible, is one variable that might be considered either in the evaluation of faculty or by a faculty member in evaluating himself
Comparing appearance-based controllers for nonholonomic navigation from a visual memory

In recent research, autonomous vehicle navigation has been often done by processing visual information. This approach is useful in urban environments, where tall buildings can disturb satellite receiving and GPS localization, while offering numerous and useful visual features. Our vehicle uses a monocular camera, and the path is represented as a series of reference images. Since the robot is equipped with only one camera, it is difficult to guarantee vehicle pose accuracy during navigation. The main contribution of this article is the evaluation and comparison (both in the image and in the 3D pose state space) of six appearance-based controllers (one posebased controller, and five image-based) for replaying the reference path. Experimental results, in a simulated environment, as well as on a real robot, are presented. The experiments show that the two image jacobian controllers, that exploit the epipolar geometry to estimate feature depth, outperform the four other controllers, both in the pose and in the image space. We also show that image jacobian controllers, that use uniform feature depths, prove to be effective alternatives, whenever sensor calibration or depth estimation are inaccurate.
THE BEATING EQUALIZER AND ITS APPLICATION TO THE SYNTHESIS AND MODIFICATION OF PIANO TONES

This paper presents an improved method for simulating and modifying the beating effect in piano tones. The beating effect is an audible phenomenon, which is characteristic to the piano, and, hence, it should be accounted for in realistic piano synthesis. The proposed method, which is independent of the synthesis technique, contains a cascade of second-order equalizing filters, where each filter produces the beating effect for a single partial by modulating the peak gain. Moreover, the method offers a way to control the beating frequency and the beating depth, and it can be used to modify the beating envelope in existing tones. The results show that the proposed method is able to simulate the desired beating effect.
When winning is not enough: learning through reflections on the ‘best‐self’

This paper explores the view that, for some, it is not enough simply to win, but to win with integrity and care. This is linked with the idea of the reflected best‐self (RBS) and RBS portraits are illustrated with short narratives from football, netball and equine sport. It is suggested that the notion of the RBS and its (re)construction adds something new and different to the principles and processes of reflective learning. The point is made that any use of narratives requires those involved to develop their narrative intelligence. The dynamic nature of RBS portraits, and in particular their (re)construction, is explained with reference to ‘thin‐slicing’ and to the impact of four types of ‘jolt’. Latterly, it is suggested that, at the coach‐athlete level, there is a clear need to place high quality connections (HQC’s) at the heart of improving performance. Supportive of this is a commitment to accentuate the positive in any process of learning through reflection. One implication of the issues raised in this paper is that coach education may have to let go of some of its silo practices and build new and creative bridges across different arenas of scholarship.
Comparison of the over-the-head, lateral and alternating positions during cardiopulmonary resuscitation performed by a single rescuer with a bag–valve–mask device

Background The 2005 guidelines for cardiopulmonary resuscitation (CPR) do not include a statement on performance of basic life support by a single healthcare professional using a bag–valve–mask device. Three positions are possible: chest compressions and ventilations from over the head of the casualty (over-the-head CPR), from the side of the casualty (lateral CPR), and chest compressions from the side and ventilations from over the head of the casualty (alternating CPR). The aim of this study was to compare CPR quality of these three positions. Methods 102 healthcare professionals were randomised to a crossover design and performed a 2-min CPR test on a manikin for each position. Results The hands-off time over a 2-min interval was not significantly different between over-the-head (median 31 s) and lateral (31 s) CPR, but these compared favourably with alternating CPR (36 s). Over-the-head CPR resulted in significantly more chest compressions (155) compared with lateral (152) and alternating CPR (149); the number of correct chest compressions did not differ significantly (119 vs 122 vs 109). Alternating CPR resulted in significantly less inflations (eight) compared with over-the-head (ten) and lateral CPR (ten). Lateral CPR led to significantly less correct inflations (three) compared with over-the-head (five) and alternating CPR (four). Conclusions In the case of a single healthcare professional using a bag–valve–mask device, the quality of over-the-head CPR is at least equivalent to lateral, and superior to alternating CPR. Because of the potential difficulties in bag–valve–mask ventilation in the lateral position, the authors recommend over-the-head CPR.
Extinction procedure induces pruning of dendritic spines in CA1 hippocampal field depending on strength of training in rats

Numerous reports indicate that learning and memory of conditioned responses are accompanied by genesis of dendritic spines in the hippocampus, although there is a conspicuous lack of information regarding spine modifications after behavioral extinction. There is ample evidence that treatments that typically produce amnesia become innocuous when animals are submitted to a procedure of enhanced training. We now report that extinction of inhibitory avoidance (IA), trained with relatively low foot-shock intensities, induces pruning of dendritic spines along the length of the apical dendrites of hippocampal CA1 neurons. When animals are trained with a relatively high foot-shock there is a high resistance to extinction, and pruning in the proximal and medial segments of the apical dendrite are seen, while spine count in the distal dendrite remains normal. These results indicate that pruning is involved in behavioral extinction, while maintenance of spines is a probable mechanism that mediates the protecting effect against amnesic treatments produced by enhanced training.
Area- and Power-Efficient Design of Daubechies Wavelet Transforms Using Folded AIQ Mapping

In this brief, we present an efficient design of a shared architecture to compute two 8-point Daubechies wavelet transforms. The architecture is based on a two-level folded mapping technique that is developed on the factorization and decomposition of transform matrices exploiting the symmetrical structure. The chip occupies a 2.08-mm2 silicon area, runs at 100 MHz, and consumes 4.51 mW of power in 0.18-m CMOS technology.
Independent component analysis and (simultaneous) third-order tensor diagonalization

Comon's (1994) well-known scheme for independent component analysis (ICA) is based on the maximal diagonalization, in a least-squares sense, of a higher-order cumulant tensor. In a previous paper, we proved that for fourth-order cumulants, the computation of an elementary Jacobi rotation is equivalent to the computation of the best rank-1 approximation of a fourth-order tensor. In this paper, we show that for third-order tensors, the computation of an elementary Jacobi rotation is again equivalent to a best rank-1 approximation; however, here, it is a matrix that has to be approximated. This favorable computational load makes it attractive to do "something third-order-like" for fourth-order cumulant tensors as well. We show that simultaneous optimal diagonalization of "third-order tensor slices" of the fourth-order cumulant is a suitable strategy. This "simultaneous third-order tensor diagonalization" approach (STOTD) is similar in spirit to the efficient JADE-algorithm.
A tri-band compact metamaterial-loaded monopole antenna for WiFi and WiMAX applications

A tri-band monopole antenna is presented, which employs metamaterial loading on a defected ground plane in order to create an antenna covering the WiFi and WiMAX bands. The measurements show monopolar-like radiation patterns at 3.50 GHz and 5.50 GHz and orthogonal dipolar-like patterns at 2.44 GHz. High radiation efficiencies are obtained in all three bands, despite the small size of the antenna, which makes it a good candidate for the wireless LAN applications.
