We present a conceptual framework that introduces key concepts capturing initial trust establishment in on-demand Virtual Organisations (VO). This framework can be used to develop trust formation protocols and policies. The framework can serve as a basis for implementing an automated system that facilitates the establishment of a VO, considerably reduces the effort for setting up a VO and conse...

We proposed a switchable beam steering device with cycloidal diffractive waveplate (CDW) for eye tracking in a virtual reality (VR) or augmented reality (AR) display system. Such a CDW diffracts the incident circularly polarized light to the first order with over 95% efficiency. To convert the input linearly polarized light to right-handed or left-handed circular polarization, we developed a br...

During the present century, a great deal of the earlier work has been confirmed and still further progress made in our knowledge of the problem. The application of iddine therapy in the prophylaxi s and treatment of goitre was commenced. In America in 1910 Marine found that goitre in brook trout could be prevented.by the administration of Iodine, subsequently he found the same, result to apply ...

Awe is a little-studied emotion with a great transformative potential. Therefore, the interest toward the study of awe's underlying mechanisms has been increased. Specifically, researchers have been interested in how to reproduce intense feelings of awe within laboratory conditions. It has been proposed that the use of virtual reality (VR) could be an effective way to induce awe in controlled e...

BACKGROUND Examining changes in brain activation linked with emotion-inducing stimuli is essential to the study of emotions. Due to the ecological potential of techniques such as virtual reality (VR), inspection of whether brain activation in response to emotional stimuli can be modulated by the three-dimensional (3D) properties of the images is important. OBJECTIVE The current study sought t...

Phobia is a type of anxiety disorder characterized by circumscribed, marked fear or anxiety to a specific object or situation which is out of proportion to the actual danger posed by the concerned object or situation. Worldwide, the prevalence of specific phobia has been found to be 16% in 13-17 years olds. In India, specific phobia has been identified as one of the most common disorders in the...

By using cloud computing it is possible to provide on- demand resources for epidemic analysis using computer intensive applications like SaTScan. Using 15 virtual machines (VM) on the Nimbus cloud we were able to reduce the total execution time for the same ensemble run from 8896 seconds in a single machine to 842 seconds in the cloud. Using the caBIG tools and our iterative software developmen...

In their Personal View, Seema Shah and colleagues1 addressed ethical issues to be considered in paediatric HIV cure research.1 The recent rebound of HIV RNA in the so-called Mississippi baby dispelled hopes of a cure, and cautions against use of the term cure.2 In a subsequent Correspondence,3 the same investigators accepted the limits of our knowledge and the complexity of the scientific quest...

Virtual Reality (VR) is successfully employed for a real huge variety of applications because it can furnish major improvement and can be really effective in fields such as engineering, medicine, design, architecture and construction, education and training, arts, entertainment, business, communication, marketing, military, exploration, and so on. Therefore great efforts have been paid over tim...
