The effect of squeeze casting process parameters on wear behavior of AC2A aluminium alloy was primarily investigated in this experimental study. Five process parameters, namely squeeze pressure, pouring temperature, die temperature, die material and compression time, each at four levels were chosen and sixteen experimental runs based on L16 orthogonal array were performed. From analysis of vari...

The power dissipation levels in high performance personal computers continue to increase rapidly while the silicon die temperature requirements remain unchanged or have been lowered. Advanced air cooling solutions for the major heat sources such as CPU and GPU modules use heat pipes and high flow rate fans to manage the heat load at the expense of significant increases in the sound power emitte...

SUMMARY  An abnormal increase in serum potassium afte-r administration of suxamethonium is known to occur in the treatment of burns, trauma, teta­nus and neurological disorders. A table shows how long this abnormal reaction lasts approxi­mately in the different categories. A few cases of cardiac arrest following suxamethonium in­jection are described in detail. The pa;thogene­sis of this abnor...

This work introduces an Abaqus CAE simulation model and its validation for freeform bending with movable die, which is extended in the of a weld seam longitudinally welded tube. The superordinate goal development soft sensor, that can derive mechanical properties bent tube as basis closed-loop control. To guarantee close monitoring properties, sensor needs to be able extrapolate spatially. Beca...

Linear control may be favorable over nonlinear control because linear design techniques greatly facilitate the controller design process and because linear controllers impose lower requirements on the implementation and operation as compared to nonlinear controllers. It is therefore a tempting idea to use linear models and linear controller design methods also for nonlinear systems. It is for i...

in this paper, the deep drawing process of tailor welded blanks is simulated using the finite element modelling and verified using the experimental results available in the literature. then the effect of die and material properties on the welding line movement is investigated. it is seen that the most effective material parameters on weld line movement are different between sheet metal thicknes...

James White lehnte 1846 die Lehre von der Dreieinigkeit als „das alte unbiblische trinitarische Dogma“ ab. Ein Jahrhundert später stimmte die Gemeinde, die er neben anderen gegründet hatte, für eine offizielle Erklärung von „Glaubenspunkten“, die den Glauben an eine Dreieinigkeit einschloss. Das eine große theologische Veränderung stattfand, ist kein Diskussionspunkt mehr. Das die meisten der f...

Statement of the Problem: Understanding about impression materials, their properties, uses and manipulation can guide operators towards having more successful restorations. Purpose: The aim of this in vitro study was to compare the accuracy of a condensation silicone impression material, Optosil, and an addition poly siloxane impression material, Elite-HD. Materials and Method: A laboratory mod...
