Der vorliegende Beitrag beschreibt eine Vorgehensweise zur modellbasierten und nutzerzentrierten Entwicklung von Mensch-MaschineSchnittstellen. In aufeinanderfolgenden Phasen der Systementwicklung werden unterschiedliche Modelle angelegt bzw. weiterentwickelt, die jeweils als Ausgangsbasis für die nächste Phase benutzt werden. Die Vorgehensweise stützt sich auf die ISO 9241-210 (Human-centred d...

Nach einer Einleitung und Diskussion tiber die Eingen­schaften der diabetischen Krankheiten wurde ausflihrlich trber die Aetiologie und Pathophysiologie der Zuckeran­kheiten,insbesondere der Altersdiabetis,gesprochen.Nach der symptomalogie der Diabetis haben wir die ncueste Einteilung der Zuckerkrankheiten genannt und die Untc­rsuchungsmethoden,die heute Uhlich sind,erwahnt;dazu wurden unsere M...

As we enter the deep submicron era, the number of transistors integrated on die is exponentially increased. While the additional transistors largely boost the processor performance, a repugnant side effect caused by the evolution is the ever-rising power consumption and chip temperature. It is widely acknowledged that the shortage of power supplied to a processor will be a major hazard to susta...

According to the requirements of concurrent engineering, three interdependency relationships (uncoupled relationship, coupled relationship and decoupled relationship) between design activities are presented in this paper. And the coupled relationship plays an important role in concurrent product design process. To represent the precedence relationships among design activities, a directed graph ...

This paper discusses the trends and developments in intelligent CAD of progressive die. The research efforts reviewed reveal the growing importance and relevancy of particular AI techniques for automation of progressive die design activities. Based on the knowledge base approach of AI, an intelligent CAD framework is developed and presented in this paper. The proposed intelligent CAD framework ...

The effect of geometrical parameters involved in vortex extrusion (VE) die design, on AA1050 aluminium alloy processed by VE were investigated using finite element analysis (FEA) and response surface methodology (RSM). For this, VE die length (L), reduction in area (RA), twist angle , and position of control points in Beziers' formulation (C1) were considered as input parameters and strain inho...

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...

Plastics extrusion is a manufacturing process suitable for continuous profiles such as floor skirtings, window frames, and pipes. In industrial applications, extrusion is a large-scale process, financially attractive only for mass products. This is due to the time consuming and costly regulation of the extrusion process and especially, the design of an extrusion die which relies on running-in e...

Active as well as passive constructional strategies and innovations were realized within a dynamic design process to guarantee sustainability at the Berlin Philological Library.1 Besides a reduction of the enveloping skin area in relation to its volume, the use of special building materials is noteworthy. This and the use of daylight and an innovative heating and ventilation system ensure the i...
