Profile extrusion is a manufacturing process used for continuous plastics profiles with a fixed cross section. The key challenge in the development of profile extrusion dies is to design the transition region between outflow and inflow of the die in such a way, that the material velocity at the outflow is homogeneous. At the current state of the art, die design is experience based and time-cons...

In the die-casting process, the formation of pores in components is unavoidable. This porosity has a harmful effect on the strength and pressure tightness of die castings. To eliminate the porosity in components, its predominant cause has to be identified as being due to either shrinkage or gas. In practice, however, it is frequently difficult to tell the difference between porosity due to shri...

Figure Number Page 1.1 CT scans (axial view) and liver segmentation. The first column shows the CT scans and the second column shows the corresponding ground truth liver segmentation.. 2.2 A set of training CT volumes. The colors represent the intensity values in the CT volumes. The shape of an organ is represented by a triangular mesh model. A triangular mesh that contains three vertex points,...

double bridge girder overhead cranes are used for heavy duty applications in theindustry. in this paper a detailed parametric design optimization of the main girder of box type isperformed for a 150ton capacity and 32m long span crane, after its basic design using availabledesign rules. design optimization is performed using detailed 3d finite element analysis bychanging the number, shape and l...

OBJECTIVE Box-shape cervical expansive laminoplasty is a procedure that utilizes a Miniplate® or Maxpacer® to achieve maximal canal expansion. This method is expected to show much larger canal expansion and good clinical outcome. So we investigated the clinical and radiological outcome of Box-shape cervical expansive laminoplasty. METHODS Between June 2008 and July 2013, we performed cervical...

Zusammenfassung. Für die Rekonstruktion mikroskopisch beobachtbarer Objekte sind aus der Literatur Verfahren bekannt, die aus mehreren lichtmikroskopischen Aufnahmen unterschiedlicher Fokussierung die Objektoberfläche rekonstruieren. Das sog. Shape-from-Focus-Verfahren berechnet dazu durch Maximierung eines Schärfemaßes für jede Pixelposition einen Höhenindex. Während diese Maximierung bei diff...
