The cross sections for charm and bottom quark production in the threshold region are discussed. We consider the effects of an all order resummation of initial state soft-plus-virtual gluon radiation on the total cross sections compared to the order αs results. This work was supported in part by the Director, Office of Energy Research, Division of Nuclear Physics of the Office of High Energy and...

Touch-screen tablets are becoming increasingly popular as office work tools. However, as current health and safety regulations applied to office equipment do not cover tablets, the importance of understanding their impact on the posture of office workers increases. As the research on ergonomic issues related to tablet use is scarce, especially in the context of office work, we explore, through ...

We present the OCTAVIS system, a novel virtual reality platform developed for rehabilitation and training of patients with brain function disorders. To meet the special requirements of clinical studies, our system has been designed with ease of use, patient safety, ease of maintenance, space and cost efficiency in mind. Patients are sitting on a rotating office chair in the center of eight touc...

The Grid technologies have brought us a set of new concepts such as utility computing, service ondemand, and resource sharing in the business scene as well as many examples of new modes of science. Although for limited applications grids are able to provide production quality of services today, we are still looking for enablers to apply them to a much broader area of use cases. Populating the I...

In this paper we evaluate spatial presence and orientation in the OCTAVIS system, a novel virtual reality platform aimed at training and rehabilitation of visual-spatial cognitive abilities. It consists of eight touch-screen displays surrounding the user, thereby providing a 360 horizontal panorama view. A rotating office chair and a joystick in the armrest serve as input devices to easily navi...

In this position paper we briefly present our application of location modeling onto office environments, in the context of our general goal of designing physical-virtual knowledge work environments.
