Das Ziel der hier vorgestellten Untersuchung war es, zu prüfen, ob Pentaerithrityltetranitrat (PETN) in der Lage ist, funktionelle und morphologische Änderungen im kardiovaskulären System zu beeinflussen, die durch eine Langzeit-NO-Synthase-Hemmung provoziert werden können. Die für die Untersuchung verwendeten 10 Wochen alten Wistar-Ratten wurden in 3 Gruppen geteilt: Die erste Gruppe diente als Kontrolle...
Cooling high-end system processors has become increasingly more challenging due to the increase in both total power and peak power density in processor cores. Junction peak temperature at worst case corner conditions often establish the limits on the maximum supportable circuit speed as well as processor chip yield. While significant progress has been made in cooling technology (e.g., cold plate design...
Among most developed sections of CAM (Computer Aided Manufacturing) utilization in area of technical praxis there is the generation of different kinds of NC programs for various manufacturing devices. Yet these CAM systems do not affect entire production in a satisfactory way. Therefore there is a need for definition of the systems of Computer Aided Manufacturing Engineering - CAME systems. CAME presents...
This article provides perspective into creation of virtual 3D models of machine parts for virtual reality application and optimization of existing machine parts by using an alternative scanning device and freeware software applications (open source elements). This alternative offers scans of components surfaces that are from the viewpoint of precision and quality comparable with much more expensive...
This article presents possibilities of intelligent assembling manufacturing process by using special tools of the augmented reality (AR) and logical procedures from related areas such as a Computer Aided Design and Planning. These possibilities are implemented in the virtual assembling environment of AR, where engineers and constructors can see important information about an exact position and orientation...
In this paper are presented information about common and advanced materials used for manufacturing of products by Fused Deposition Modelling (FDM) rapid prototyping technology. In different rapid prototyping technologies the initial state of material can come in either solid, liquid or powder state. In solid state it can come in various forms such as pellets, wire or laminates. The current range materials...
