The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...

This work is concerned with the integration of the two networking paradigms of ICN and SDN in order to provide an enhanced evolutionary path from today’s IP networks towards ICN. We introduce a scheme that allows for the operation of SDN based infrastructure, which provides network-wide ICN awareness. Further, an advanced approach, which allows for the forking of ICN packets throughout the SDN ...

Die Workshops Software-Reengineering (WSR) im Physikzentrum Bad Honnef wurden mit dem ersten WSR 1999 von Jürgen Ebert und Franz Lehner ins Leben gerufen, um neben den internationalen erfolgreichen Tagungen im Bereich Reengineering auch ein deutsch-sprachiges Diskussionsforum zu schaffen. Ziel der Treffen ist es, einander kennen zu lernen und auf diesem Wege eine direkte Basis der Kooperation z...

 Background: Advanced type 2 diabetes mellitus (T2DM) needing insulin therapy is a common disease. Previous studies indicate that aloe (Aloe vera L.) leaf gel may positively affect the blood glucose and lipid levels in patients with advanced T2DM needing insulin.  Objective: Evaluation of the efficacy and safety of aloe leaf gel in the treatment of type 2 diabetic patients resistant to ...

A fully integrated planar sensor for 77 GHz automotive applications is presented. The frontend consists of a transceiver multichip module and an electronically steerable microstrip patch array. The antenna feed network is based on a modified Rotman-lens and connected to the array in a multilayer approach offering higher integration. Furthermore, the frontend comprises a phase lock loop to allow...

Surface acoustic wave (SAW) technology has been featured in numerous publications for more than a decade because of the performance advantages and design flexibility. With the increasing of the frequency, the electrical effects become more important. The accurate prediction of the frequency response relies on a combination of good acoustic modeling techniques, rigorous die and package parasitic...
