The traditional line-of-sight ultraviolet model cannot serve better for link performance study for the reason that the scattering characteristic is often ignored in the modelling process. Therefore, a line-of-sight ultraviolet bipyramid model in combination with transceiver full beam angles and geometrical relationship of the transceiver field of view intersection is established. The theoretica...

Recent models which describe our world as a brane embedded in a higher dimensional space introduce new geometrical degrees of freedom, associated with spatial variations in the position of the brane and the size of the extra dimensions, that can be coherently excited by symmetry breaking in the early universe even on "mesoscopic" scales as large as 1 mm. The characteristic frequency and intensi...

The stability of linear time-delay systems whose characteristic equations include three delays is investigated. Using geometrical relations in the polynomial plane, a graphical method is presented to visualize the stability domains in the three-dimensional space of time delays. Also, in this space, the surfaces on which the number of unstable poles of the system changes, are identified and an a...

One of the key biological materials that can be used for disease diagnosis is the blood. The first step to examine the blood is separation of molecules in blood. In this work, the meander structure based microfluidic channel with different dimensions is designed for filtering applications. The performance characteristic of microchannel is analysed for symmetric and asymmetric geometries. The ge...

With exponentially increasing integration densities and shrinking characteristic geometries on a chip, the wires, rather than devices, become the dominant factor in deciding the performance, power consumption, and reliabilities of a VLSI system. Previous researches on the interconnectcentric design methodologies mainly concentrate on optimizing individual nets. Instead of searching for the best...

Spin structures of nanoscale magnetic dots are the subject of increasing scientific effort, as the confinement of spins imposed by the geometrical restrictions makes these structures comparable to some internal characteristic length scales of the magnet. For a vortex (a ferromagnetic dot with a curling magnetic structure), a spot of perpendicular magnetization has been theoretically predicted t...

This paper describes a color classification technique for the color subspaces definition based in 3D reconstruction approaches. These color subspaces use implicit functions to create a bounding surface that will fit a set of characteristic color samples to define a particular color. The implicit subspace reconstruction allow to define clusters of arbitrary shape for a better approximation of th...

We study the problem of characterizing quasiconvex hulls for three “solenoidal” (divergence free) wells in dimension three when the wells are pairwise incompatible. A full characterization for a generic regime is achieved by translating the problem into the language of H-measures, following recipes of Kohn and Smyshlyaev & Willis, in combination with certain ideas based on Šverák’s example of a...

In this paper, a three dimensional spiral cochlear finite element model is established based on the experimental data of the actual right human ear to study the curvature effect on the amplitude of the spiral basilar membrane (BM). Harmonic response analysis is then carried out. The simulation results are in good agreement with the published experimental results, which confirm the validity of t...
