?? A steering arm, made from a three piece weldment was creating problems in manufacturing. It was converted to a one piece impression die hot forging at a 13% reduction in weight and reduced manufacturing cost. ?? A cast hub for a large power shovel in a coal field failed, causing an estimated downtime of four to six weeks at a cost of $4000 per hour. The hub was slightly redesigned as an open...

die erlebnislyrik umfasst die gedichte, in denen es um die erinnerung eines lyrischen ichs an ein geschehen geht, wobei mit dem gedichtschreiben ein erinnerungsvorgang in gang gesetzt wird, der einen bezug zwischen dem erlebenden ich und dem geschehen schafft und damit ein unmittelbares erleben erzeugt. die speziellen mittel der lyrik wie reim, rhythmik, klang, melodie, wiederholung, bildsprach...

This paper provides an overview of the thermal and power challenges in emerging high performance computing platforms. The advent of new sophisticated applications in highly diverse areas such as health, education, finance, entertainment etc. is driving the platform and device requirements for future systems. The key ingredients of future platforms are vertically integrated (3D) die-stacked devi...

Hot–press forming steels are formed in a fully austenitic state followed by die– quenching in order to generate martensite and achieve a strong steel. The ductility however, tends to be limited. We explore in this work a novel steel design in which the forming operation is in the two–phase austenite and ferrite field, so that the quenching results in a dual–phase ferrite and martensite microstr...

We point out the priority of our paper (Mahajan et al. 2001) over (Aschwanden et al. 2007) in introducing the term ”Formation and primary heating of the solar corona” working out explicit models (theory as well as simulation) for coronal structure formation and heating. On analyzing the (Aschwanden et al. 2007) scenario of coronal heating process (shifted to the chromospheric heating) we stress...

es wird gezeigt, dass bei der standiger zunahme der production von roheisen ,die fast ausschliesslich in hochofen erfolgt, der gestelldurchmesser und die ofeneinheit zunimmt demgegenuber der spezifische brennstoffverbrauch abnimmt. weiterhin wird die entwicklungsrichtung der stahlerzeungsverfanren wegen der wirtschaftlichen und technischen hinsicht untersucht und festgestellt, dass nuter versch...

This paper reviews the advantages of substituting die-cast copper for aluminum in the motor rotor. This advance in motor technology has been long sought by the motor industry but short die life due to the high melting point of copper frustrated attempts to manufacture by pressure die casting. The nickel-base alloy hot die technology developed to solve the manufacturing problem is briefly review...

We find a closed-form for the distribution function (defined in terms of a Wigner operator) for hot coloured particles in a background gluon field, in the hard thermal loop approximation. We verify that the current is the same as that derived from the known effective action.
