In this work it is reviewed the most novel advances in the multipactor RF breakdown risk assessment devoted to RF satellite microwave passive devices employed in space telecommunication systems. On one side, it is studied the effect of transmitting a single-carrier digital modulated signal in the multipactor RF voltage threshold in a coaxial line. On the other hand, an analysis of the multipactor...
This paper presents a 2D flow visualization user study that we conducted using new methodologies to increase the objectiveness. We evaluated grid-based variable-size arrows, evenly spaced streamlines, and line integral convolution (LIC) variants (basic, oriented, and enhanced versions) coupled with a colorwheel and/or rainbow color map, which are representative of many geometry-based and texture-based...
Virtual Reality (VR) systems cannot be promoted for complex applications (involving the interpretation of massive and intricate databases) without creating natural and ”transparent” user interfaces: intuitive interfaces are required to bring non-expert users to use VR technologies. Many studies have been carried out on multimodal and collaborative systems in VR. Although these two aspects are usually...
