Development of PMSM Drives for Hybrid Electric Car Applications

Permanent synchronous electric machine (PMSM) drives for the FAW hybrid electric car is investigated in this paper. The power system configuration of the FAW is introduced. The influences of the stator winding turn and the permanent magnet width on the torque-speed characteristic are analyzed. The torque-speed characteristic that the specification required is obtained by proper choice of these two parameters. The torque ripple and the harmonic contents of the electromotive force (EMF) are decreased by rotor shape optimizing to improve the traction performance and the supply quality. The rotor shape is optimized by the offset arc method. The analysis is verified by the sample PMSM experimentation
Observer Reactor System Core report probe App 1 App 2 observation difference App 3 System

Cloud scale provides the vast resources necessary to replace failed components, but this is useful only if those failures can be detected. For this reason, the major availability breakdowns and performance anomalies we see in cloud environments tend to be caused by subtle underlying faults, i.e., gray failure rather than fail-stop failure. In this paper, we discuss our experiences with gray failure in production cloud-scale systems to show its broad scope and consequences. We also argue that a key feature of gray failure is differential observability: that the system’s failure detectors may not notice problems even when applications are afflicted by them. This realization leads us to believe that, to best deal with them, we should focus on bridging the gap between different components’ perceptions of what constitutes failure.

Collaborative spectrum sensing based on the ratio between largest eigenvalue and Geometric mean of eigenvalues

In this paper, we introduce a new detector referred to as Geometric mean detector (GEMD) which is based on the ratio of the largest eigenvalue to the Geometric mean of the eigenvalues for collaborative spectrum sensing. The decision threshold has been derived by employing Gaussian approximation approach. In this approach, the two random variables, i.e. the largest eigenvalue and the Geometric mean of the eigenvalues are considered as independent Gaussian random variables such that their cumulative distribution functions (CDFs) are approximated by a univariate Gaussian distribution function for any number of cooperating secondary users and received samples. The approximation approach is based on the calculation of exact analytical moments of the largest eigenvalue and the Geometric mean of the eigenvalues of the received covariance matrix. The decision threshold has been calculated by exploiting the CDF of the ratio of two Gaussian distributed random variables. In this context, we exchange the analytical moments of the two random variables with the moments of the Gaussian distribution function. The performance of the detector is compared with the performance of the energy detector and eigenvalue ratio detector. Analytical and simulation results show that our newly proposed detector yields considerable performance advantage in realistic spectrum sensing scenarios. Moreover, our results based on proposed approximation approach are in perfect agreement with the empirical results.
Role of a Service Corridor in ICU Noise Control, Staff Stress, and Staff Satisfaction: Environmental Research of an Academic Medical Center

OBJECTIVE: To investigate the role of a dedicated service corridor in intensive care unit (ICU) noise control and staff stress and satisfaction. BACKGROUND: Shared corridors immediately adjacent to patient rooms are generally noisy due to a variety of activities, including service deliveries and pickups. The strategy of providing a dedicated service corridor is thought to reduce noise for patient care, but the extent to which it actually contributes to noise reduction in the patient care environment and in turn improves staff performance has not been previously documented. METHODS: A before-and-after comparison was conducted in an adult cardiac ICU. The ICU was relocated from a traditional hospital environment to a new addition with a dedicated service corridor. A total of 118 nursing staff participated in the surveys regarding pre-move and post-move environmental comfort, stress, and satisfaction in the previous and new units. Acoustical measures of noise within the new ICU and a control environment of the previous unit were collected during four work days, along with on-site observations of corridor traffic. RESULTS: Independent and paired sample t-tests of survey data showed that the perceived noise level was lower and staff reported less stress and more satisfaction in the new ICU (p < 0.01). Analyses of acoustical data confirmed that the new ICU was significantly quieter (p < 0.02). Observations revealed how the service corridor impacted patient care services and traffic. CONCLUSIONS: The addition of a dedicated service corridor works in the new unit for improving noise control and staff stress and satisfaction.
Glucose utilization of cerebral gliomas measured by [18F] fluorodeoxyglucose and positron emission tomography

Positron emission tomography was used to measure local cerebral glucose utilization by the 2-[18F]fluoro-2-deoxy-D-glucose technique in 23 patients with cerebral gliomas. All 10 high-grade (III and IV) astrocytomas demonstrated a region of high activity with a glucose consumption of 7.4 ± 3.5 (SD) mg/100 gm per minute. The 13 low-grade (I and II) gliomas had a glucose metabolic rate of 4.0 ± 1.8 mg/100 gm per minute, with no distinctly visible hot spot. Thus, we found a correlation between rate of glycolysis and malignancy in primary cerebral tumors. Cerebral cortical glucose utilization was often depressed in areas adjacent to or neurally connected to the tumor site, and there was focal irregular delta wave EEG activity in these areas.
Validity and reliability of a new method for measuring putting stroke kinematics using the TOMI® system

Abstract The purpose of this study was to determine the validity and reliability of a new method for measuring three-dimensional (3D) putting stroke kinematics using the TOMI® device. A putting robot and a high-speed camera were used to simultaneously collect data for the validity evaluation. The TOMI® device, when used in conjunction with standard 3D coordinate data processing techniques, was found to be a valid and reliable method for measuring face angle, stroke path, putter speed, and impact spot at the moment of ball contact. The validity of the TOMI® measurement system was quantified using the 95% limits of agreement method for each aforementioned variable. The practical significance of each validity score was assessed by incorporating the maximum estimated measurement error into the stroke of the putting robot for 10 consecutive putts. All putts were executed from a distance of 4 m on a straight and flat synthetic putting surface. Since all putts were holed successfully, the measurement error for each variable was deemed to be negligible for the purposes of measuring putting stroke kinematics. The influence of key kinematic errors, at impact, on the outcome of a putt was also determined.
« C’est qui TGV ? » Contextualisation de l’enseignement dans le premier degré à La Réunion

L’academie de La Reunion compte en 2009, quarante sept enseignants possedant l’habilitation Langue et Culture Regionale. Outre quelques enseignants itinerants, le seul dispositif present dans l’Academie est celui des classes bilingues et seuls dix professeurs des ecoles exercent en classes bilingues experimentales sur un total de 6434 enseignants du premier degre, soit 0,1% de l’effectif des professeurs des ecoles. Malgre le terme pompeux d’habilitation Langue ET Culture regionale, dans les faits et dans la pedagogie, la culture est absente. A aucun moment, n’est evoquee, dans l’Academie, la question d’une quelconque prise en compte de la culture reunionnaise, la possibilite d’une contextualisation de l’enseignement. Cet article s’appuie sur des observations et des engagements, notamment pedagogiques, vieux de vingt annees. Il tente de montrer que sans contextualisation de l’enseignement, sans reelle prise en compte de la culture reunionnaise, sans formation des enseignants a cette culture, sans operationnalisation des connaissances transmises, les « classes bilingues », au nombre anecdotique, n’ont, au mieux, qu’un role de vitrine, de bonne conscience institutionnelle dans un departement dont, faute de formation, beaucoup, enseignants, comme membres des corps d’inspection, disent qu’il n’est pas different d’un departement metropolitain.
A measure of treatment response: patient and physician satisfaction with traditional NSAIDs for osteoarthritis control

Purpose The clinical response to traditional nonsteroidal anti-inflammatory drugs (tNSAIDs) varies substantially. The objective of this study was to describe physicians’ and patients’ perceptions of response to tNSAIDs as measured by satisfaction with control of patients’ osteoarthritis (OA). Patients and methods A cross-sectional survey was undertaken in 2009 in Germany, Spain, and the UK. Linked physician and patient questionnaires collected data on OA management, degree of pain and disability, and satisfaction with OA control. Results The study included 363 treating physicians and 713 patients receiving tNSAIDs. Patient mean (standard deviation) age was 65.5 (11.0) years (range 36–94 years); 60% were women; 86% were white; and one-quarter were obese. Dissatisfaction with control of patients’ OA was expressed by physicians or their patients, or both, for 51% of patients, including 208 patients (31%) with mild OA and 478 patients (60%) with moderate or severe OA. Overall, 37% of patients reported dissatisfaction and 34% had a physician who reported dissatisfaction. Patient and physician assessments were the same in 70% of cases; Cohen’s κ coefficient was 0.34 (95% confidence interval 0.26–0.41), indicating fair agreement. Of those reporting dissatisfaction, most physicians (79%) and patients (64%) believed that the current control was the best that could be achieved. The most common reasons for which physicians reported dissatisfaction were inadequate response (56%), side effects (11.1%), and poor tolerance (7.8%). Conclusion One-half of patients or their treating physicians were dissatisfied with the control of OA provided by tNSAID therapy; moreover, most believed it was the best control that could be achieved.
Stratégies de prise en charge de la polyarthrite rhumatoïde : quelle place pour les médicaments biosimilaires ?

Le cout des biomedicaments impacte lourdement le fardeau financier deja important impose par la polyarthrite rhumatoide (PR) a la societe. Le but de ce travail etait de rechercher les motivations de la prescription des medicaments biosimilaires en rhumatologie, tout particulierement pour prendre en charge les patients atteints de PR. Les travaux effectues ont permis d’estimer les economies annuelles realisables en France avec le medicament biosimilaire de l’infliximab a 13,6 millions d’EUR, pour la seule prise en charge de la PR. Par ailleurs, une enquete menee aupres des rhumatologues et pharmaciens a permis d’identifier les principaux enjeux lies a l’utilisation de ces medicaments. Enfin, le suivi de leur utilisation en region Grand Est entre 2015 et 2016 rend compte de leur utilisation encore modeste. La mise sur le marche reguliere de medicaments biosimilaires, combinee a l’experience croissante des acteurs et aux dispositifs d’incitation mis en place, devraient permettre de faire progresser la part d’utilisation de ces medicaments dans les prochaines annees, et de s’assurer qu’ils tiennent bien leurs engagements sur le plan des economies realisees.
Study of the drug release kinetics in nanoscale micelle to micelle system

A new drug delivery model is proposed in vitro in a micelle to micelle system. Gold nanoparticeles can be encapsulated by micelles of amphiphilic diblock copolymers; it provides an environment to incorporate drug molecules, forming the Au@polymer-drug conjugates. Gold nanoparticles are fluorescent quenchers, allowing the release kinetics of fluorescent probes from nanoparticles to be followed by fluorescence spectroscopy. Herein, we synthesized the Au@PSPAA-dye conjugates, and investigated the release kinetics in pure water and empty polymeric micelle aqueous solution with fluorescence spectroscopy. The results show that the release kinetics is a fast and diffusion-controlled process in the presence of empty micelles; while the water is not the ultimate acceptor in the absence of perfect sedimentation. The homogeneous mixed micelle to micelle release system avoids the material transfer in bulk phase, which may real reflect the release mechanism in vivo.
Facilitating Process Changes in Meal Delivery and Radiological Testing to Improve Inpatient Insulin Timing Using Six Sigma Method

Background The objective of this project was to improve the timing of inpatient insulin administration related to meal delivery and the scheduling of radiology tests by Lean Six Sigma method. Methods A multidisciplinary hospital team and a Six Sigma team from a pharmaceutical manufacturer collaborated to evaluate food delivery and radiology scheduling processes related to the timing of insulin administration. Key factors leading to problems within each system were addressed to improve the efficiency of each process while improving the timeliness of glucose testing and insulin administration. Results Standardizing the food delivery schedule and utilizing scorecards to track on-time meal deliveries to the floor enabled nursing to more accurately administer insulin in coordination with the delivery of meals. Increasing communication and restricting the scheduling of inpatient procedures during mealtimes reduced disruptions to insulin administration. Data at 6 months postimplementation demonstrated that the institution met goals for most primary outcome metrics including increasing on-time meal delivery and the proportion of patients taking insulin scheduled for radiology tests during appropriate times. Conclusion By implementing the recommendations identified via Lean Six Sigma, this collaborative effort improved the timing of inpatient insulin administration related to meal delivery and radiology testing.
Integrated analysis of the inter-arm coordination in aquatic locomotion

Segundo a teoria da abordagem ecologica, a capacidade de adaptar os movimentos as restricoes de interaccao dinâmica de um ambiente de prova, para atingir intencoes especificas e de tomar decisoes, define amplamente a expertise. Os objetivos desta tese foram: (i) investigar quais sao as variaveis que mais influenciam a coordenacao em natacao na tecnica de crol e compreender os seus efeitos sobre a flexibilidade, durant a manipulacao de constrangimentos da tarefa; e (ii) analisar oefeito de diferentes treinos especificos de coordenacao e forca na coordenacaode nado e rendimento na tecnica de crol em jovens nadadores. O protocolo foi composto por dois protocolos distintos: (i) 15 x 50 m na tecnica de crol (com intervalo de 5 min) com cinco repeticoes em cada 100, 90 e 70% da sua velocidade maxima aos 50 m, aleatoriamente a 90, 95, 100, 105 e 110% da sua frequencia de nado preferida; e (ii) os nadadores foram avaliados quanto a sua antropometria e flexibilidade e realizaram 30 s maximos em nado amarrado, 12 x 25 m no MAD-system e 50 m maximos na tecnica de crol. Foram utilizadas sete câmeras aereas e seis sub-aquaticas para avaliar a cinematica, com coordenacao dos membros superiores calculada atraves de duas metodologias: a fase relativa continua (permitindo extrair os tempos relativos dispendido em em-fase, anti-fase e fora-de-fase) e o indice de coordenacao. Os resultados indicaram que a velocidade e a frequencia de ciclo foram os principais parametros de controlo, com a velocidade a exercer uma maior influencia. Atraves da manipulacao destes parâmetros verificou-se que nem toda a variabilidade e funcional, isto e, a natureza dos padroes e uma apropriada alteracao entre padroes parecem ser mais importantes do que atingir o maior numero de mudancas de padroes motores. O rendimento nos 50 m parece variar mais com o genero do nadador do que com o nivel de habilidade nestas idades, onde os treinos especificos (o mesmo meio ambiente: o treino de coordenacao e de forca na agua) exercendo mais alteracoes nas variaveis coordenativas e o treino de forca no ginasio a exer maior influencia no rendimento.
ZigBee based effective multihop communication in wireless sensor networks using sleep / wakeup scheduling protocols

Wireless sensor Networks (WSNs) are a really appealing solution for several sensible applications. Recently, WSNs have conjointly been deployed in industrial eventualities, even for vital applications. Two major needs are required for a good deployment of WSNs in such eventualities. The first is energy efficiency, as a network lifetime within the order of months or years is typically needed. The other is reliability, since a good moderate message loss can't be tolerated in vital applications. In this paper we tend to assess the performance of the IEEE 802.15. 4 standard in multi-hop WSNs wherever sleep/wakeup scheduling protocols are used for energy conservation. We tend to show through extensive simulation results that the MAC parameter settings considerably impact on the performance. we tend to demonstrate however an applicable tuning of the MAC parameters can improve the reliability of communications, resulting in a really high delivery ratio. In addition, our solution additionally obtains low energy
Endodontic regeneration and tooth revitalization in immature infected sheep teeth

AIM To examine the response of immature sheep teeth with infected root canal systems to a commonly used pulp regeneration/revitalization protocol. METHODOLOGY Immature mandibular right first incisors in four sheep were mechanically exposed and the pulps infected. The mandibular left first incisors remained intact as controls. Five weeks later, the experimental root canals were chemo-mechanically cleaned and dressed with a triple-antibiotic paste for 4 weeks, before bleeding was induced inside the canal by mechanically irritating the periapical tissues. A collagen dressing was packed coronally onto the blood clot and the canal orifice sealed with mineral trioxide aggregate and glass ionomer cement. Six months later, the mandibles were collected and the teeth with associated periapical tissues were analysed radiographically, with CT scanning, and by histology. The changes in root length, dentine thickness in the apical third (mesially and distally), and apical diameter were analysed using Student's t-test. RESULTS Radiographs revealed significant increases in root length, root wall thickness and narrowing of the apical diameter of the canals after treatment (P < 0.05), with no significant differences in root diameters found between the experimental and the control teeth (P > 0.05) on both radiographic and CT results. Root maturation and thickening of the walls due to hard tissue deposition was confirmed by histology in all experimental teeth. Hard tissues in the apical portion of the root were more developed than in the coronal portion. CONCLUSION Endodontic regeneration and tooth revitalization procedures in immature infected sheep teeth showed positive outcomes with similar increases in root length and development to the control teeth.
Ab initio experimental analysis of realistic resonant ring metamaterial lenses

Metamaterials — artificial composites having emergent properties not available in Nature — became a subject of interest for the scientific community after the first experimental demonstration of an artificial medium with simultaneously negative ε and μ [1]. Among their most important novel applications was the possibility of fabricating a super-lens with sub-wavelenght resolution [2]. Actually, it was soon recognized that this effect is severely restricted by the losses and the discrete nature. Analysis of losses leads to a well known formula for the minimum resolution of the lens (see, for instance, [3] and references therein)
Alterations in the protein synthetic apparatus of Friend erythroleukemia cells infected with vesicular stomatitis virus or herpes simplex virus

We have compared the effects of infection with herpes simplex virus (HSV) and vesicular stomatitis virus (VSV) on the protein synthetic apparatus of Friend erythroleukemia cells. Previous studies demonstrated that infection with HSV rapidly shuts off the synthesis of globin and other cellular polypeptides (Y. Nischioka and S. Silverstein, 1977, Proc. Natl. Acad. Sci. U.S.A. 74: 2370-2374). In contrast to these findings, globin synthesis persists in Friend erythroleukemia cells infected with VSV. Physical measurements of the size of bulk-infected cell mRNA, using hybridization with polyuridylic acid, demonstrated that there was no detectable change in the size of mRNA's after infection with VSV. A comparison of the kinetics of hybridization of cytoplasmic RNA extracted from cells infected with either HSV or VSV with globin complementary DNA revealed that by 4 h postinfection with HSV only about 15% of the globin mRNA sequences remained, whereas there was no discernible change in the sequence abundance of globin mRNA in VSV-infected cells.
Learning Software Behavior for Automated Diagnosis

Software diagnosis algorithms aim to identify the faulty software components that caused a failure. A key challenges of existing software diagnosis algorithms is how to prioritize the outputted diagnoses. To do so, previous work proposed a method for estimating the likelihood that each diagnosis is correct. Computing these diagnosis likelihoods is nontrivial. We propose to do this by learning a behavior model of the software components and use it to identify abnormally behaving components. In this work we show the potential of such an approach by performing an empirical evaluation on a synthetic behavior model of the components. The results show that even an imperfect behavior model is useful in improving diagnosis accuracy and minimizing wasted troubleshooting efforts.
Modeling the Region Patent Applications Based on P-SVM and SA

The domestic patent applications by region (DPAR) are complex to conduct due to its nonlinearity of influenced factors. It is necessary to make a trade off among these factors when some of them conflict. A novel way about nonlinear regression modeling of DPAR with the potential support vector machines (P-SVM) is presented in this paper. In the model development, a simulated annealing (SA) algorithm is employed to optimize P-SVM parameters selection. Using a set of real data from China, simulation results show that the SA optimization algorithm is robust. The results also indicate that methods based on the P-SVM perform are better than the ones based on the standard SVM in both model generalization and DPAR forecasting accuracy.
