In this article, we investigate the movement and vibrations of a blade due to presence mast. When passes in front mast, sudden pressure spike induces blade. To study influence stiffness, two different structures were studied. We present our numerical schemes concerning resolution flow, behavior structure coupling systems. Then, validate methods against an experiment (Bahaj et al., 2007). third ...

Multiple choice questions (MCQs) are commonly used for assessment in higher education. With increased use of on-line examination it is likely that the usage MCQs will be even more years to come. It therefore interest examine some characteristics these type such as effect number distractors and "None above" (NOTA) or "All (AOTA) options. The tutor-web an open-source, drilling system freely avail...

Rob Kling’s editorship of The Information Society (TIS) from 1995 to his sudden passing on May 15, 2003 was a unique moment in the life of TIS or for that matter any research journal. He operated above paradigms and methodologies, and his editorial instincts were receptive to research from all traditions. Our tendency is to ease into intellectual cubbyholes where fellow researchers conveniently...

The purpose of this study was to assess the speed differential threshold—if there is one—at which drivers decide to pass a lead vehicle. Drivers in a simulator encountered vehicles in front that were programmed to travel at speeds that were similar, slightly below, or even slightly above the drivers own speed. The study involved a total of 152 such passing opportunities. In almost all of the en...

Now a day’s multi-core architecture introduces new challenges for effective implementation of inter-core communication, as Inter-core communication plays an important role to balance the delay in a multicore processor. The two mechanisms used for inter-core communication are sharedmemory and message-passing communications. Shared-memory communication fails to provide sufficient scalability with...

Even for electrical appliances, testing for illegal behaviors becomes difficult since the software system in an electrical appliance has already become large in size. Actually, the conventional method cannot generate sufficient test items for illegal behaviors. But testing illegal behaviors becomes more and more important, since the failure of electrical appliances would cause fatal effects on ...

Abstract Background and purpose: Priority health-risk behaviors, often are established during childhood and adolescence, extend into adulthood, and are interrelated and preventable. This study was conducted to determine and compare the prevalence of risky behaviors on both sexes of freshman students enrolled in Tehran University, Iran. Materials and Methods: This study was a descriptive-analyti...
