The filling process of thermoformed cups with food like yogurt is followed by placing a laminated aluminum foil for hermetic sealing on top of the cup. By today’s standards the sealing of the thermoformed aluminum foil with the cup is primarily realized by contact heat with a hot stamp. ... En savoir plus

Introduction The monitoring of bacteria concentration in drain fluid is the most common way to estimate the success of a colon surgery. However, the lack of efficient method to follow the development of E.coli in drain fluid after surgery is often fatal to the patient. The proposed ... En savoir plus

Over the last decade, ambient vibration energy harvesting by piezoelectric materials has been an area of extensive research. This technology enables to convert wasted mechanical energy available in our environment into useful electrical energy to power up autonomous wireless sensors ... En savoir plus

This paper presents the two dimensional (2D) Finite Element Method (FEM) COMSOL Multiphysics® model of a PCB-Coil layout. The model comprises of different coil layouts for sake of comparison. The scientific goal of the simulation is to find an optimized arrangement with a high quality ... En savoir plus

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It ... En savoir plus

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... En savoir plus

Micro-machined ultrasound transducers have a wide range of applications. As a sensor or actuator they can be used for measuring fluid speed and direction, to mix and excite particles (sonication), for taking images (ultrasonography), for non-destructive testing and many other purposes in ...

Ultra-cold atomic systems have proven over the last decade to be a excellent platform for the realization of quantum sensors, quantum computation or quantum simulation applications. A special implementation of this technology is the so called atom chip, where the magnetic fields ... En savoir plus

The topic of my work is modeling of a multimodal waveguide microprobe which is suitable for deep brain infrared stimulation. The goal of the research is the investigation of the therapeutic effect of optical IR excitation on biological active substances. In the physical model I ... En savoir plus

In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ... En savoir plus
