The term “collision detection” refers to the task of determining whether, in a given set of objects, any two intersect. If they do, then common collision detection systems return either one such pair or all such pairs. The term “proximity computation” refers to a more general task where we determine the nearest or the “most overlapping” pairs of objects. In the article, we present a new method ...

Simulations for training and analysis incorporating haptic feedback are becoming more popular and the sophistication of these simulations is increasing. Many systems now allow a range of simulated rigid tools to be used in haptic feedback applications, such as scalpels in surgical simulations. However, very often the rigid property of the simulated tool does not correspond to the flexibility of...

Computer worms are very active and new sophisticated versions continuously appear. Signature-based detection methods work with a low false-positive rate, but previously knowledge about the threat is needed. Anomaly-based intrusion detection methods are able to detect new and unknown threats, but meaningful information for correct results is necessary. We propose an anomaly-based intrusion detec...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

In this paper, the spatial property of the magneto-static field generated by the stable current is discussed and exploited in image analysis. The region-division feature of the magnetic field generated by a current element on 2D plane is investigated experimentally for some simple test images. The virtual edge current in gray-scale images is presented by a magneto-static analogy, which is compo...

The present review paper has several objectives. Its primary aim is to give an idea of the general features virtual element methods (VEMs), which were introduced about a decade ago in field numerical for partial differential equations, order allow decompositions computational domain into polygons or polyhedra very shape. Nonetheless, also addressed readers who have already heard (and possibly r...

Collision detection is the foundation of interaction in virtual reality. In Virtual design workspace, virtual assembly workspace, and virtual training, for example, the motion of virtual objects must be constrained by collisions with other objects to provide the sense of reality. Important human-object interactions such as grasping, hitting, moving, etc., in virtual reality (VR) environments ar...

There are many researches to detect collision between real object and virtual object in 3D space. In general, these techniques are need to huge computing power. So, many research and study are constructed by using cloud computing, network computing, and distribute computing. As a reason of these, this paper proposed a novel fast 3D collision detection algorithm between real and virtual object u...
