Many clinical examinations involve palpation and part of the diagnostic process depends on the application of pressure. Teaching and learning such skills is difficult especially for internal examinations. A modification to a veterinary virtual reality (VR) simulator, the Haptic Cow, was planned to teach safe and effective use of pressure for bovine pregnancy diagnosis. Expert technique was capt...

The effectiveness of virtual environment systems depends critically on the end-to-end delay between the user's motion and the update of the display. When the user moves, the graphics system must update the images on the display to reflect the proper projection of the virtual world on their field of vision. Significant delay in this update is perceived as swimming of the virtual world; objects i...

in islamic civilization, rhetoric is the product of a great attempt to find out the secrets of quranic language; nevertheless, the achievements of such studies have been mechanically applied to persian which, compared to arabic, has a different linguistic system and literary conventions. this approach has brought about problems in defining literary terms, internal rhythm being one of them. this...

virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...

An energy model that correlates fan airflow, head, speed, and system power input is essential to detect device faults optimize control strategies in systems. Since the application of variable-frequency drives (VFDs) makes motor-efficiency data published by manufacturers inapplicable for VFD–motor–fan systems, efficiency drive (belt–motor–VFD) must be identified each individual obtain accurate m...
