BACKGROUND Collision detection and response are two crucial aspects in a virtual surgery simulator, which significantly affect the output in real-time response and simulation realism. METHODS We propose a collision detection algorithm which employs a novel hierarchical spatial hashing to effectively achieve appropriate parameters. Thereafter we present a hybrid collision response scheme which...

The aim of the present research is to analyse how some Roma in Romania become educationally mobile. Based on cultural wealth model and constructivist approaches ethnicity scholarship relation racism, I intended take stock forms capital persons make use when ascending. considered that narrative type interviews could be a successful means generating better understanding meaning functioning capita...

Mixed Reality applications put very high demands on both the visual realism and the rendering times of computer graphics elements that are to be perceived as part of the physical scene. This paper presents novel techniques to render photorealistic trees in real-time Mixed Reality. Animation of the tree branches leads to a realistic effect of the tree swaying in the wind. To enhance the effect o...

In this paper it will be addressed the possibility of an account of novel predictions of unexpected phenomena by physical theories within van Fraassen's anti-realism. In particular it will be considered two important cases in modern physics, the prediction of the bending of light in Einstein's theory of gravity, and the prediction of antimatter in quantum electrodynamics. It will be defended th...
