One of the main problems in wind energy conversion system (WECS) is how to achieve maxim­u­m output power in different wind speeds. Maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. So, using these methods practically will follow with high price and an abundant difficulties. In this pape...

CONTEXT Medicine is a highly visual discipline. Physicians from many specialties constantly use visual information in diagnosis and treatment. However, they are often unable to explain how they use this information. Consequently, it is unclear how to train medical students in this visual processing. Eye tracking is a research technique that may offer answers to these open questions, as it enabl...

n engl j med 369;12 nejm.org september 19, 2013 1085 Over the past several decades, major changes have caused the medical community to reconsider current educational models. These changes include increasing education costs, shifts in health care needs, the demographics of the applicant pool, and many scientific, pharmacologic, and technological advances resulting in increased specialization of ...

AFFECTIVE computing has come a longway from its humble beginnings. Starting with a seminal paper by Rosalind Picard [1], it has evolved into an interdisciplinary field with its own IEEE Transactions and numerous special issues in other journals. One of the main goals of affective computing is to create machines which can adapt to users’ emotions in order to produce more natural and efficient in...

The hospitality industry, and as a consequence hospitality education, are extremely sensitive to global events such as the 2003 SARS epidemic or the 2004 South East Asian Tsunami disaster. This paper presents a case study of Swiss Hotel Schools, where a student survey has been used to monitor fluctuations in attitudes and satisfaction on a longitudinal basis. The survey began in 2000 on one cam...

This paper investigates the problem of coordinated tracking of a linear multi-agent system subject to actuator magnitude saturation and dead zone characteristic with input additive uncertainties and disturbances. Distributed consensus and swarm tracking protocols are developed from a low-and-high gain feedback approach. Under the assumption that each agent is asymptotically null controllable wi...

Patient education objectives are included as a strategy in every health promotion area addressed in Healthy People 2000. The likelihood of accomplishing these objectives is linked to the accuracy of the baseline estimates of practice. These estimates have most usually relied upon patient and physician reports. However, the accuracy of these reports has been infrequently studied. We analyzed aud...

index tracking is the process of developing a portfolio that reproduces the performance of an index. the tracker portfolio has relatively good diversity and low turnover and low transaction costs. in this paper we applied a binary programming model for index tracking problem. in this model the number of assets for portfolio construction is defined by portfolio manager. the robust optimization f...
