We show how to efficiently compute 2D polyhedral bounds of the (elliptic) perspective projection of a 3D sphere that has been clipped to the near plane. For the special case of a 2D axis-aligned bounding box, the algorithm is especially efficient. This has applications for bounding the screen-space effect of an emitter under deferred shading, bounding the kernel in density estimation during ima...

Face book is virtual and cybernetic network which causes an effective force and among the youth. It shows that if the usage of the face book network increases at home the rate of the interaction and the bounding social capital decreases as well. It also indicates that the effect of face book usage among the young people has increased already. Through a questionnaire by a survey method, more tha...

This chapter considers interpolation and curve tting using generalized polynomials under bounded measurement uncertainties from the point of view of the solution set (not the parameter set). It characterizes and presents the bounding functions for the solution set using interval arithmetic. Numerical algorithms with result veri cation and corresponding programs for the computation of the boundi...

The communication between an honest prover and an honest verifier can be intercepted by a malicious man-in-the-middle (MiM), without the legitimate interlocutors noticing the intrusion. The attacker can simply relay messages from one party to another, eventually impersonating the prover to the verifier and possibly gaining the privileges of the former. This sort of simple relay attacks are prev...

We present the CEM (Conditional Expectation Maximization) algorithm as an extension of the EM (Expectation Maximization) algorithm to conditional density estimation under missing data. A bounding and maximization process is given to speci cally optimize conditional likelihood instead of the usual joint likelihood. We apply the method to conditioned mixture models and use bounding techniques to ...

A large body of work in both the theoretical and experimental literature suggests that upper bound implications in simple sentences with bare numerals are entailments arising from the semantics of the numeral, rather than scalar implicatures of the sort seen with other scalar terms. However, not all semantic analyses of numerals designed to introduce upper bounding entailments in simple sentenc...
