The usefulness of a virtual character depends on its ability to fulfill the user’s expectations: among other aspects, the character’s appearance should match her/his personality as well as her/his behavior [11]. It has indeed been shown that the better a character looks the part, the more believable and effective she/he will be in the narrative [13, 8]. This paper presents a system which genera...

We present a noncircularity measure for 2D (two-dimensional) shapes and an approach to the computation of the Euler number based on the Slope Chain Code (SCC). The SCC was developed for representing and analyzing open and closed curves in the 2D domain. Now, in this paper we describe more properties of the SCC, such as: the independence of scaling and starting point for simple closed curves, ar...

This paper focuses on the buckle propagation pressure of a pipe-in-pipe system under uniform external pressure. After validation finite element model used in this research, several effects were studied. At first, initial imperfection inner pipe, including ovality and eccentricity, checked out. Second, influence scantling outer pipes was tested. It found that dominant factor which affects mode i...

In analogy to the Eisenfeld-Lakshmikanthammeasure of nonconvexity and theHausdorffmeasure of noncompactness, we introduce two mutually equivalent measures of noncircularity for Banach spaces satisfying a Cantor type property, and apply them to establish a fixed point theorem of Darbo type for multifunctions. Namely, we prove that every multifunction with closed values, defined on a closed set a...

In this paper, we develop widely linear transmit strategies for two-way relaying networks with single or multiple pairs of users and a MIMO amplify and forward relay. By taking advantage of the noncircularity of the complex-valued transmitted signals, a significant performance gain is obtained over linear transmit strategies when SNR balancing or relay transmit power minimization is chosen as t...
