Virtually all fibers exhibit some dimensional and structural irregularities. These include the conventional textile fibers, the high-performance brittle fibers and even the newly developed nano-fibers. In recent years, we have systematically examined the effect of fiber dimensional irregularities on the mechanical behavior of the irregular fibers. This paper extends our research to include the ...

In this study we perform precise geometrical 3D reconstructions of high complex neuronal architectures. First, confocal microscopy was used to scan neurons with submicron resolution. Second, we extracted the center-lines and diameters of the neuron by means of our reconstruction method, and third we used these metric data to generate compartment models that were transported into the proprietary...

The source resistance of a heterojunction field-effect transistor ~HFET!, whose reduction is mandatory for high-performance devices, consists of an ohmic contact resistance and an access resistance. The access region is located between the geometrical source and the geometrical source side of the gate contact. By means of a quantum-mechanical modeling program, the effect of changes in layer str...

Introduction: Today, facial bio-potential signals are employed in many human-machine interface applications for enhancing and empowering the rehabilitation process. The main point to achieve that goal is to record appropriate bioelectric signals from the human face by placing and configuring electrodes over it in the right way. In this paper, heuristic geometrical position and configuration of ...
