Flexible dielectric waveguides have been demonstrated at 10 GHz and 94 GHz using thin-wall polymer tubing filled with low-loss, high-dielectric-constant powders. Absorptive losses of the order of 10 dB/meter were measured at 94 GHz with nickel-aluminum titanate and barium tetratitanate powder in polytetrafluoroethylene (F’TFE) lightweight electrical spaghetti. Bending losses at 94 GHz were negl...

Welcome to this special issue ofWireless Personal Communications. This special issue comprises a selection of best papers from the First International Conference on Mobility for Life: Technology, Telecommunication and Problem Based Learning (TTPBL) Conference. This three days event provided a dynamic platform for experts, scholars, higher education policy makers and private sector parties from ...

A coarse-grained computational model is used to investigate the effect of a fluid membrane on patchy-particle assembly into biologically relevant structures motivated by viral cores and clathrin. For cores, we demonstrate a nonmonotonic dependence of the promotion of assembly on membrane stiffness. If the membrane is significantly deformable, cores are enveloped in buds, although this effect is...

The paper describes a scheme for the implementation of low power cores for hearing aid applications. Power saving features of the scheme are two fold. The first due to the utilisation of a macro-component framework which allows the rapid assembly of the cores on easy-to-verify hierarchical plug-in basis. The second is due to the system-on-chip strategy. The cores are embedded within an ARM-base...

This is the first study on the free vibrational behavior of sandwich panels with flexible core in the presence of smart sheets of oil which is capable of the excitation of magnetic field. In order to model the core, the improved high order theory of sandwich sheets was used by a polynomial with unknown coefficients first degree shear theory was used for the sheets. The derived equations based o...

......VLSI technology’s increased capability is yielding a more powerful, more capable, and more flexible computing system on single processor die. The microprocessor industry is moving from singlecore to multicore and eventually to manycore architectures, containing tens to hundreds of identical cores arranged as chip multiprocessors (CMPs). Another equally important direction is toward system...

The strain field of isolated screw and edge dislocation cores in aluminum are calculated using density-functional theory and a flexible boundary condition method. Nye tensor density contours and differential displacement fields are used to accurately bound Shockley partial separation distances. Our results of 5-7.5 A (screw) and 7.0-9.5 A (edge) eliminate uncertainties resulting from the wide r...
