In this paper a semi cylindrical fluid filled hyperelastic finger model for soft contact has been developed from the basic principles of mechanics. The deformation parameters namely contact width and radial deflection were calculated for different applied forces. To validate this analytical model, compression tests were conducted on silicone rubber finger specimens . Contact width and radial de...

The tentative of reproducing a biological eye with artificial electronic devices has always had a major drawback. In fact there is an important difference between how a human eye sees the world and how a standard video camera does: while the common visual sensors generally have constant resolution on each part of the image, in their biological counterparts the picture elements are arranged in o...

Dynamical bipedal walking has been a key objective in robotics since its origins, due to the human curiosity about artificial anthropomorphic beings which gave rise to the robot concept itself [Capek 1973]. As could be seen in most industrialized countries, the industrial manipulators have found a wide adoption, and there is little space to a major boost in the area [Yonemoto et al. 1985]. Alth...

Specific absorption rate (SAR) induced inside human head in the near-field of a mobile phone antenna has been investigated for three different SAR resolutions using Finite Difference in Time Domain (FDTD) method at GSM 900 band. Voxel based anthropomorphic human head model, consisting of different anatomical tissues, is used to calculate the peak SAR values averaged over 10-g, 1-g and 0.1-g mas...

Humans communicate affect through a variety of channels, such as facial expressions, voice and body movement, and are adept at estimating the affective states of others. Body movements are important observable features of underlying affective states. The psychology literature reports on the critical role of movement cues in conveying life-like affective expressions for both anthropomorphic and ...

Amorphous silicon (a-Si) electronic portal imaging devices (EPIDs) are x-ray detectors frequently used in radiotherapy imaging and dosimetry applications. EPIDs employ a copper plate and gadolinium oxysulfide phosphor screen with an array of a-Si photodiodes to indirectly detect incident radiation. In this study, a previously developed Monte Carlo (MC) model of an aSi EPID has been extended for...
