The motion of a relativistic charged particle in an external specified field planer single- and multifrequency circularly polarized electromagnetic wave large amplitude the presence constant uniform magnetic (the Redmond field) when consideration is required has been analyzed detail. It shown that kinetic energy multi-frequency depends not only on intensity wave, frequencies carrier but also di...

This paper presents a novel approach for navigating in a Panorama-Based Virtual Environment (PBVE). A PBVE was constructed for the arbitrary view synthesis when navigating. Uses can interact with PBVE through augmented 3D graphic objects. Unlike traditional imagebased virtual environment (VE) systems in which the functions of presenting 3D geometry and human-system interaction are very limited,...

Room-temperature thermoelectric power S has been systematically studied in a chain-free double-layer Y1-xCaxBa2Cu3O6. As a function of hole concentration per planer Cu atom (Ppl), S(Ppl) of Y1-xCaxBa2Cu3O6 (Ppl=x/2) behaves identically to that of single-layer La2-xSrxCuO4 (Ppl = x). We demonstrate the phase diagram for the double CuO2 layer YBa2Cu3Oy and Bi2Sr2CaCu2Oy system as a function of th...

This paper describes an easily manufactured, reducedsize, active receiving antenna for automotive applications, which increases short-range wireless detection in the 315-MHz band. This compact antenna has an advantage over currently available antennas because can be hidden in a vehicle’s interior. The active antenna consists of a low-noise amplifier coupled to a low-profile planer meanderline p...

There has been always a workspace problem with parallel mechanisms. We have proposed a parallel mechanism with linear passive joints to adjust link length. This parallel mechanism can have different workspaces by adjusting link length. When these workspaces are combined, it has larger workspace. We have tried to control the link lengths of this parallel mechanism not actively but passively usin...
