In humans, facial symmetry has been linked to an individual's genetic quality, and facial symmetry has a small yet significant effect on ratings of facial attractiveness. The same evolutionary processes underlying these phenomena may also convey a selective advantage to symmetrical individuals of other primate species, yet to date, few studies have examined sensitivity to facial symmetry in non...

With the development of the theory of wavelet transform, biorthogonal wavelet filter banks with linear phase and compact support characteristics are widely used in signal and image processing. We study the multiscale edge detection using anti-symmetrical biorthogonal wavelet filter banks with the same even length based on the analysis of the properties of this wavelet filter banks. The steps of...

in this paper we enumerate fuzzy subgroups, up to a natural equivalence, of some finite abelian p-groups of rank two where p is any prime number. after obtaining the number of maximal chains of subgroups, we count fuzzy subgroups using inductive arguments. the number of such fuzzy subgroups forms a polynomial in p with pleasing combinatorial coefficients. by exploiting the order, we label the s...

This paper studies the effects of symmetrical voltage sags on the operational characteristics of a Permanent Magnet Synchronous Motor (PMSM) by Finite Element Method (FEM). Voltage sags may cause high torque pulsations which can damage the shaft or equipment connected to the motor. By recognizing the critical voltage sags, sags that produce hazardous torque variations could be prevented. Simula...

Symmetrical peripheral gangrene is an ischemic necrosis simultaneously involving the distal portions of two or more extremities without any proximal arterial obstruction or vasculitis. It may occur as a result of a large number of infectious and non-infectious causes. A few cases of symmetrical peripheral gangrene associated with cardiac disease have been described in the literature. We describ...

Non-Symmetrical Plastic Collapse Modes of a Symmetrically Loaded Circular Cylinder. P18stic collapse modes of a thick-walled homogeneous cylinder under circularly-symmetrical loading (internal and external normal pressures) are analyzed. Ideal plasticity, I-IUBEIt-~ISES-HENC]~Y yield condition, incompressibility and plane strain conditions are assumed. The possibility of existence of non-syrm~e...
