In this paper we present a new functional traversal abstraction for processing OO data structures that decomposes traversal computation into three function objects and a traversal control function. Function objects compute and combine values over a general traversal while the control function allows programmers to limit the extent of a traversal. Our new abstraction is supported by a Java libra...

Common cold is one of the most frequently encountered problem in pediatric practise. Homeopathy offers a wide range medicines absolutley safe, unlike harmful corticosteriods and antiinflammatory medications given allopathy inorder to suffice need an acute phase common cold.

We present a new stackless ray traversal algorithm which makes use of kD-tree augmented with sparsely distributed bounding boxes. The proposed traversal algorithm is not restricted to start the hierarchy traversal at the root node and so it can exploit the knowledge of the ray origin. The algorithm achieves traversal times comparable with the traditional hierarchical traversal as well as recent...
