The Virtual Space Robotics Testbed serves as a decision support system in various space mission scenarios mostly rendezvous and docking (RvD), planetary landing and exploration. Therefore, various tests with real and virtual hardware were made in the testbed for rendezvous and capture (INVERITAS). Our simulation system allows the generation of virtual images and the test of virtual camera syste...

This paper initially examines theories proposed by Feenberg abouttechnical systems and alternative modernity, analyzes his thoughts, andconcludes that a framework of values needs to be provided in shapingtechnical systems. In a society like Iran, where policy makers are looking forthe realization of Islamic values, this framework of values is derived fromIslam. To explain the relationship betwe...

If one is interested solely in processor speed, one must use virtually-indexed caches. The traditional purported weakness of virtual caches is their inability to support shared memory. Many implementations of shared memory are at odds with virtual caches—ASID aliasing and virtual-address aliasing (techniques used to provide shared memory) can cause false cache misses and/or give rise to data in...

Recent experiments investigating the acoustic cues that underlie distance perception for nearby sources provide important insights into how distance cues can be incorporated into virtual auditory displays. Potential distance cues considered include overall level, reverberation, and interaural level differences. Perceptual research shows that the relative utility of these cues depends on the typ...

Introduction: Nowadays, use of virtual socail networks is increasing . However, few studies have been conducted  about  factors influencing the use of social networks by using theories of health education  among students.  The present study was to determine predictive factors of virtual social networks among students of Yazd university of medical sciences based on the constr...

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...
