FruityMesh Implementation of a battery-efficient mesh network on top of Bluetooth Low Energy

This thesis introduces a mesh implementation for purely battery-powered nodes that works on top of the Bluetooth 4.1 specification and proposes the FruityMesh algorithm to solve the complicated task of autonomous meshing and maintenance. Current state-of-the-art scientific, BLE and other mesh networks are presented before discussing possibilities and limitations of Bluetooth Low Energy. A simulation…

Conceptualisation and Optimization of a Collaborative and Tooldriven Development Process for HMI-Graphic and Operating Procedure Specification

In the development of complex automotive HMI systems, car manufacturers don’t make use of their full potential. Although efficient reference processes and innovative development approaches exist companies prefer the application of established methods and tools. The shift towards new development approaches takes place slowly and step by step to avoid a negative impact on running…

Information retrieval and visualization on mobile Devices and their practical realization using semantical text analysis

Analyzing textual information using semantic methods has become a necessity in order to control the increasing amount of information and its condensed presentation on the small displays of mobile devices. A large knowledge base is a prerequisite for such algorithms. In this work, we present a new algorithm which uses the structured database Freebase and…
