Tube hydroforming (THF) process is used to produce the complex components from the initial cylindrical tubes. In this paper, T- shape component was formed using a tube hydroforming machine and the residual stresses of hydroformed tube was determined by hole drilling method. Subsequently, the thickness distribution and residual stresses of final tube were investigated using experimental and fini...
This paper aims to simulate an immiscible two-phase flow in two-dimensional T-shaped, modified cross-shaped, and cross-shaped micromixers numerically. The effects of various parameters, including Capillary number, phase rate ratio, channel width on the generation droplets were studied. Also, modification T-shaped was proposed. results reveal that equidistant tiny are generated compared ordinary...
In this paper, we study a new problem of finding a convex drawing of graphs with a non-convex boundary. It is proved that every triconnected plane graph whose boundary is fixed with a star-shaped polygon admits a drawing in which every inner facial cycle is drawn as a convex polygon. Such a drawing, called an inner-convex drawing, can be obtained in linear time.
A low cost, dual band antenna has been proposed and studied in this paper. The antenna consists of two elementsa T-shaped element and an F-shaped element. A microstrip feed line with a characteristic impedance of 50? has been used to feed the T-element which is responsible for the generation of the higher band of operation. The F-element is placed on the other side of the dielectric and is coup...
Star-shaped conjugated systems with varying oligofluorene arm length and substitution patterns of the central BODIPY core have been synthesised, leading to two families of compounds, T-B1-T-B4 and Y-B1-Y-B4, with T- and Y-shaped motifs, respectively. Thermal stability, cyclic voltammetry, absorption and photoluminescence spectroscopy of each member of these two families were studied in order to...
In oorplanning it is common that a designer wants to have certain modules abutting with one another in the nal pack ing Unfortunately few oorplanning algorithm can han dle abutment constraints although this feature is useful in practice The problem of controlling the relative positions of an arbitrary number of modules is non trivial Slicing oorplans have an advantageous feature that the topolo...
