The study investigates the impact of white matter directional conductivity on brain current density under the influence of Transcranial direct current stimulation (tDCS). The study employed different conductivity estimation algorithms to represent conductivity distribution in the white matter (WM) of the brain. Two procedures, one mathematically driven and(More)
Multi Agent Systems (MAS) are expected to be involved in futuristic technologies. Agents require some execution environment in which they can publish their service interfaces and can provide services to other agent. Such execution environment is called Agent Platform (AP). From a technical point of view any abnormal behavior of platform can distress agents(More)
The focus of this study is to estimate the contribution of regional anisotropic conductivity on the spatial distribution of an induced electric field across gray matter (GM), white matter (WM), and subcortical regions under transcranial direct current stimulation (tDCS). The assessment was conducted using a passive high-resolution finite element head model(More)
In recent years there has been significant use of regular cross-polytopes (regular octahedrons or hyper-diamonds) as constructs to simplify problem solving in high-dimensional database queries, collision detection algorithms and graphic rendering techniques. Many of the algorithms for these applications use minimum volume bounding boxes as approximations of(More)
This paper presents a novel approach that transforms the feature space into a new feature space such that a range query in the original space is mapped into an equivalent box query in the transformed space. Since box queries are axis aligned, there are several implementational advantages that can be exploited to speed up the retrieval of query results using(More)
