In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...

In Section 1 we describe the Sorites paradox and lay out options for a solution. In Section 2 we consider approaches which deny that all premises are true, and note that these solutions all seem open to a certain serious objection. In Section 3 we note a problem for the principle of transitivity of the conditional and present a contextualist resolution of the problem, according to which the “co...

Minkowski in 1908 used space-like binary velocity-field of a medium, relative to an observer. Hestenes in 1974 introduced, within a Clifford algebra, an axiomatic binary relative velocity as a Minkowski bivector. We propose consider binary relative velocity as a traceless nilpotent endomorphism in an operator algebra. Any concept of a binary axiomatic relative velocity made possible the replace...

In the most of speaker recognition system, speaker's characteristics is extracted from acoustic parameter by speech analysis and we make speaker's reference pattern. we obtain more exact performance by using dynamic characteristic and constant characteristic by speaking habit. Therefore we suggest following to solve this problem. First thing is using prosodic information by characteristic vecto...

INTRODUCTION The current method in dealing with pediatric hip pathologies is to avoid joint replacement unless absolutely necessary. This decision is typically made on a scientific basis. However, this is not necessarily the correct approach in all cases as demonstrated in the following case report where social issues is an extremely important variable to be considered when deciding on surgical...
