For little q-Jacobi polynomials, q-Hahn polynomials and big q-Jacobi polynomials we give particular q-hypergeometric series representations in which the termwise q = 0 limit can be taken. When rewritten in matrix form, these series representations can be viewed as decompositions into a lower triangular matrix times upper triangular matrix. We develop a general theory of such decompositions rela...

Various species of high intensity highly charged state heavy ion beams with small emittance are required in many fields including particle physics, medical uses, inertial fusion, and simulator of space radiations. Direct Plasma Injection Scheme (DPIS), we have developed for several years, is a unique scheme to provide heavy ion beams to meet the above requirements. A high-density plasma created...

The paper presents the results of an experimental study a vertical wind turbine type Darrieus with frontal cylindrical guide vane unit. main goal research is to analyze influence geometry classical unit on active and passive zone turbine. aerodynamic scheme synthesized by classic runner vanes. Three different guiding devices model frontally located vanes have been studied. Their characteristics...

Droplet breakage is a common phenomenon in converting pipe flow to swirl vane-type separator (VTPS)’ inlet. The evaluation of the dispersed droplet sizes after crucial optimum design inlet structure and estimation oil-water separation performance. This paper studies behavior produced by guiding vanes. Experiments are performed with two different vanes at VTPS. oil droplets downstream measured s...

Triangular norms in the study of probabilistic metric spaces as a special kind of associative functions defined on the unit interval. These functions have found applications in many areas since then. In this study, we present new methods for constructing triangular norms and triangular conorms on an arbitrary bounded lattice under some constraints. Also, we give some illustrative examples for t...

Abstract This paper takes the guiding blade of a type aero-engine needle as research object for icing problem and uses numerical simulation method to simulate airflow field, supercooled water droplet impact situation on surface under different flight conditions, analyze influence speed blade. It is found that incoming flow velocity has significant effect guide vanes, with increasing from 34m/s ...
