Event Consolidation and Analysis Tool for E-Banking
(2011)The CREALOGIX E-Banking AG develops and distributes the CLX.E-Banking system, an online banking system used by several domestic and international banking institutions. The goal of this thesis was to design and implement two extensions to the system, a forensic analysis tool and an additional security system. <br/><br/> A forensic analysis tool is required to monitor the interactions between the e-banking system and its customers. It enables ...Master Thesis -
Analysis of approximation algorithms for the traveling salesman problem in near-metric graphs
(2011)We consider the beta-metric traveling salesman problem (Delta-beta-TSP), i.e., the TSP restricted to input instances satisfying the beta-triangle inequality c({v,w}) <= beta * (c{v,u} + c{u,w}), for any three vertices u,v,w. The well-known path matching Christofides algorithm (PMCA) provides an approximation ratio of 3/2 * beta^2 and is the best known algorithm in the range 1 <= beta <= 2. We show that this upper bound is tight by providing ...Master Thesis -

Operational Space Control of Single Legged Hopping
(2011)Fast, ecient and versatile locomotion is the objective of the cutting-edge research of legged robots. Researchers are faced with two basic questions: First, what kind of motion is required to move the robot fast and ecient? Second, how has the robot to be controlled to achieve this motion? A well-known approach in the research area is to characterize the demanded motion by a so-called template, a simplied physical model that generates the ...Master Thesis
