We describe visualization software, Visualizer, that was developed specifically for interactive, visual exploration in immersive virtual reality (VR) environments. Visualizer uses carefully optimized algorithms and data structures to support the high frame rates required for immersion and the real-time feedback required for interactivity. As an application developed for VR from the ground up, V...

Semantic Desktop systems appear to be a promising infrastructure for context-aware applications that acquire and make use of user context information in order to provide more efficient interaction between the user and the system. In a systematic analysis, we have analyzed existing Semantic Desktop systems based on a collection of requirements and deduced from it architectural implications for f...

In this paper, we show how one can leverage a Semantic Web application development environment to define an application that is a Semantic Desktop browser called HyperSD. In addition, special wrappers have been defined to allow importing regular desktop objects, such as files, person records, calendar entries, etc... into the semantic desktop accessed through HyperSD.

BACKGROUND Digital surveillance using internet search queries can improve both the sensitivity and timeliness of the detection of a health event, such as an influenza outbreak. While it has recently been estimated that the mobile search volume surpasses the desktop search volume and mobile search patterns differ from desktop search patterns, the previous digital surveillance systems did not dis...

Desktop grids is an important class of distributed computing infrastructures (DCIs) used for solving complex scientific problems. The inherent complexity of DCIs and used technologies limit the wide adoption of distributed computing in practice. Everest is a web-based distributed computing platform that uses service-oriented approach and cloud computing models to solve this problem. This paper ...

The manifested dominance split-brain monkeys usually show for performing visual tasks through one hemisphere, when perceptual information is equally available to both, was analyzed. Three split-brain monkeys, each being trained similar yet different discriminations to each hemisphere, were allowed the opportunity to choose between the two problems when both were presented simultaneously. Initia...

Accelerometer is one of the prominent sensors which are commonly embedded in new age handheld devices. Accelerometer measures acceleration forces in three orthogonal axes X, Y, Z. The raw acceleration values obtained due to the movement of device in 3D space which is hosting accelerometer can be used to interact and control wide range of applications running on the device and can also be integr...
