In this paper, on-body propagation modelling has been investigated applying various numerical computational techniques. Propagation measurements with body-worn antennas have been carried out at 2.4GHz inside and outside an anechoic chamber respectively for narrowband communication channel characterisation. Both simulation and measurement results have been(More)
Rho-family GTPases regulate cytoskeletal dynamics in various cell types. p21-activated kinase 1 (PAK1) is one of the downstream effectors of Rac and Cdc42 which has been implicated as a mediator of polarized cytoskeletal changes in fibroblasts. We show here that the extension of neurites induced by nerve growth factor (NGF) in the neuronal cell line PC12 is(More)
Millimeter-wave automotive radars are currently being used for adaptive cruise control. To extend their application to collision warning and collision avoidance, increased capability is required in the assessment of hazards and the environment. A signal processing scheme called the advance path measurement (APM) algorithm, which extracts the trajectory of(More)
In this paper a review of recent research in characterizing on-body wireless channels is presented. Path gain random variations caused by body movements in various environments have been investigated at several frequencies, including 2.45 GHz and 5.8 GHz. In a scattering environment, such as an office, the fading of on-body channels was found to undergo a(More)
Low-profile, compact and easily integrated body worn antennas are the essence of efficient, reliable and user-friendly body-centric networks. The paper presents different planar printed ultra wideband (UWB) antennas and their applications as part of on-body communication systems. Both frequency and time domain characteristics of the proposed antennas are(More)
This paper combines artificial neural network (ANN) technique with the finite difference time domain (FDTD) technique. A detailed illustration of the concept, in this paper, uses a 3-8-1 feedforward artificial neural network (FF-ANN) for approximating the Z-component of the electric field in a rectangular waveguide in TM mode. The FDTD equation (i.e., the(More)
