We examine a “mere newness bias,” a preference for novelty purely due to recentness of release. In a series of studies, we show that, for newer and older products of identical quality, people prefer newly released goods over older goods across a range of domains. This bias translates to a higher willing to pay, greater anticipated excitement, and higher likelihood of purchase for products perce...

In diesem Bericht werden die Ergebnisse der Studienarbeit mit dem Thema: ”Evaluation von UML – Werkzeugen“ präsentiert, die an der Hochschule Bremen im Sommersemester 2006 durchgeführt wurde. Die Arbeit hatte die Evaluation von kostenlos verfügbaren UML – Werkzeugen im Hinblick auf die Brauchbarkeit in hochschulinternen studentischen Ausbildungsprojekten zum Ziel. Es wurden Werkzeuge untersucht...

Twist extrusion process is a rather new route to produce highly strained materials. In this process, severe plastic deformation is applied by large shear strains. In current article, required energy for twist extrusion by use of admissible velocity field together with the upper bound technique is predicted. The proposed model is capable of considering the effect of various parameters such as di...

Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

In this paper, a generalized expression for the flow field in axisymmetric extrusion process is suggested to be valid for any dies and the boundary shapes of the plastic deformation zone. The general power terms are derived and the extrusion force is calculated by applying upper bound technique for a streamlined die shape and exponential functions for shear boundaries. It is shown that assuming...

Guillian Barré-sindroom is die mees algemene polineuritis. Motoriese funksies word tot ’n groter mate as sensoriese funksies aangetal en die diagnose berus gewoonlik op simmetriese, distale en perifere spierswakheid. Sterftes aan die sindroom is gewoonlik die gevolg van respiratoriese arres en dus is vroeë diagnose en respiratoriese ondersteuning noodsaaklik. Terapeutiese sowel as verpleegsorg ...

Onderwys moet altyd ’n doel voor oë hou en die doel van verpleegonderwys is pasiëntsorg van ’n hoë gehalte. Duidelike doelstellings dien as wegwysers vir die onderwyser en student. Die kriteria van ’n hoë peil van versorging ontstaan uit die waardes van die sam elewing. O nderrigdoelstellings berus ook op waardes en moet aan die hand van die waardesisteem van die sam elewing waarin die beroep f...
