Die Analyse des Zugriffsverhaltens auf Web-Seiten ist von großer Wichtigkeit, um die Attraktivität und Nützlichkeit von Internet-Angeboten zu bewerten und Rückschlüsse auf eine Verbesserung der WebPräsentation zu erhalten. Im kommerziellen Umfeld (E-Commerce-Angebote wie Online-Buchhandel, -Reisebuchung, etc.) soll die sogenannte “Click Stream”-Analyse wertvolle Informationen über das Zugriffsv...

A large amount of packaging used mainly in the food industry is obtained by technologies that involve use machines such as those cut with flexible die. The durability die a very important aspect and this regard purpose research was to identify for its development. Thus, considered analysis knives made 50CrMo4 steel considering hard chrome-plating treatment, well laser hardening knives. For tool...

Motivated by the test data sets of ISPRS WG III on image understanding we investigate the feasibility of building extraction using high resolutionDigital Surface Models DSM as input data which do not only contain information about the topographic surface like Digital Elevation Models DEM but also information about the buildings The steps of the proposed procedure increasingly use explicit domai...

This research presents a new flexible bending machine and its practical applications. The proposed machine uses a new method. When tubes are fed into the fixed and mobile dies, they are bent by shifting the relative position of the mobile die. The bending radius is controlled by the relative distance and orientation between the mobile die and the tube. The bending angle is controlled by the len...

Cold drawing process is one of the most used metals forming processes in industries for forming seamless tubes. This process of plastic deformation of metals occurs below the recrystallization temperature and is generally performed at room temperature. When metal is cold worked, upon the release of forming force, the springback occurs. In this paper, the springback effect of the seamless tube t...

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...

In diesem Beitrag wird ein hybrides Leistungsbündel konzipiert, mit dessen Hilfe die energieeffiziente Planung und Steuerung sowie der Betrieb und die Nutzung von IT-Infrastruktur sichergestellt werden. Das Vorgehen zur Entwicklung orientiert sich an einem etablierten Vorgehensmodell des Product-Service-SystemsEngineering und basiert auf zwei Industrieworkshops mit über 60 Teilnehmern aus Wisse...

Strain distribution of Al 1100 was numerically investigated during cyclic expansion extrusion (CEE) process using finite element method (FEM). Die angle, corner fillet radius and die chamber diameter were considered as die parameters and friction factor and number of passes as process parameters. The effects of these parameters were investigated on the effective strain and strain homogeneity in...

Thermal expansion and hot deformation are two phenomena causing dimensional errors in investment casting. This error occurs in dimensions between the die and wax pattern. Therefore, the wax's thermo-physical and thermo-mechanical properties, the metal die features, and the process parameters affect the dimensions of the wax pattern. Some important effective process parameters are the injection ...

Ziel: Ziel der Studie war die Häufigkeit von typischen Artefakten der high-pitch Computertomografie (HPCT) bei low-dose Untersuchungen von Kindern im Vergleich zur MDCT zu evaluieren und die effektive Dosis (Deff) zu berechnen. Material und Methoden: 35 Patienten (17 Jungen, 18 Mädchen; Durchschnittsalter 112±69 Monate) wurden in diese retrospektive Studie eingeschlossen. Bei allen Patienten wu...
