Abstract Given the high proportion of wind power frequency/voltage stability problems, system based on synchronized coordinates (DFIG) mathematical model doubly-fed motor, studies a current source containing inertial link type turbine virtual synchronous control strategy, and loop design inner ring. Established in Matlab/Simulink simulation generator, generator realized inertia. Simulation resu...

New York City faces the challenge of an ever-increasing homeless population with almost 60,000 people currently living in city shelters. In 2015, approximately 25% of families stayed longer than 9 months in a shelter, and 17% of families with children that exited a homeless shelter returned to the shelter system within 30 days of leaving. This suggests that ”long-term” shelter residents and tho...

Nowadays, where public projects are more and more committed to sustainable development, the user perception become a determinant factor for the decision-making process. This paper targets to evaluate the use of an immersive, multisensory and interactive method based on virtual reality (VR) system in order to study human behaviour and perception. Today, non-immersive, non-interactive and mono-se...

OBJECTIVE We aimed to evaluate the relationship between establishing an animal shelter in Erzurum and the number of suspected rabies bites between the years 2005 and 2012. MATERIALS AND METHODS A retrospective, repeated cross-sectional study was planned in Erzurum in the year 2013. Records between the years 2005 and 2012 were obtained from the Communicable Diseases Department of the Erzurum H...

Accurate speed estimation is essential for dynamic analysis of rotating machinery; particularly for condition monitoring and operational modal analysis of applications with significant load and speed variation. The wind turbine is such an application. However, a sufficiently accurate tachometer, to keep track of the instantaneous speed, is not always available in field conditions. This opens th...

Wind and warmth sensations proved to be able to enhance users’ state of presence in Virtual Reality applications. Still, only few projects deal with their detailed effect on the user and general ways of implementing such stimuli. This work tries to fill this gap: After analyzing requirements for hardware and software concerning wind and warmth simulations, a hardware and also a software setup f...
