The research was carried out to optimize parameters for evaluating an improved motorize maize sheller. Statistical analysis performed using response surface methodology (RSM) with 3 by factorial experiment replicates. three are speed (850 rpm, 950 rpm and 1100 rpm), moisture content (12, 15, 17%) feed rate (120 kg h-1, 130 h-1 140 h-1) used illustrate the ability of machine shell (throughput ca...

This study investigated the performance of symmetric airfoils type NACA0012 numerically under different operating conditions. It has been assumed that involves steady state, non-compressive, and turbulent flows. The fluid was air. effect Reynolds number angle attack on lift drag coefficients, pressure distribution, velocity distribution investigated. ANSYS FLUENT used to solve numerical model b...

A simple calculus based on generative communication is introduced; among its primitives, it contains a conditional input operation that tests for presence (or absence) of an output, reminiscent of the inp predicate of Linda. We study three different operational semantics for the output operation, called instantaneous, ordered and unordered. The associated behavioural semantics are obtained as t...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

in this paper, the effect of transmembarne pressure (tmp) at levels of 1, 1.75 & 2.5 bar, process temperature (t) at levels of 30 & 60oc and operation time (t) at levels of 15, 30, 45 & 60 minute on the permeate flux, sugar rejection, non-sugar rejection and fouling as membrane performance indexes investigated. membrane system used in this research was ceramic tubular module and it had effectiv...
