In this paper, an inhomogeneous human body model was proposed to study the in-body radio channels (I-BRCs) for wireless implants, and numerical simulations were carried out with finite-difference time-domain (FDTD) method. Specifically, parameters such as channel gain and group delay were studied for different links according to implant locations, namely, from intra-brain to the surface of chest,...
Body-centric wireless communication, which is accepted as an important part of the fourth generation mobile communications systems, provides a prospective communication solution for implantable devices in personal health care. In this paper, an inhomogeneous human body model was proposed to study the in-body radio channels for wireless implants, and numerical simulations were carried out with the...
Przedstawiono tendencje w konstrukcji układów chłodzenia i dostępne komercyjne metody modelowania pracy układu chłodzenia. Przeprowadzono obliczenia symulacyjne temperatury cieczy komercyjnym programem komputerowym AmeSIM i porównano wyniki z pomiarami wykonanymi na hamowni podwoziowej. Opisano wybrane procesy wymiany ciepła występujące w układach chłodzenia. Przedstawiono ogólny model elementu cieplnego...
