T2 - European and Mediterranean Conference on Information Systems N2 - As the potential of a Next Generation Network (NGN) is recognized, telecommunication companies consider switching to it. Although the implementation of an NGN seems to be merely a modification of the network infrastructure, it may trigger or require changes in the whole company and even influence the company strategy. To capture the effects of NGN we propose a framework based on concepts of business engineering and technical recommendations for the introduction of NGN technology. The specific design of solutions for the layers "Strategy", "Processes" and "Information Systems" as well as their interdependencies are an essential characteristic of the developed framework. We have per-formed a case study on NGN implementation and observed that all layers captured by our framework are influenced by the introduction of an NGN.

High Quality Streaming beschäftigt sich mit High Definition Television und Mehrkanal Sound. In diesem Beitrag werden die Technologien und Anwendungsperspektiven für HD Medien-Dienstleistungen beschrieben. Der Beitrag entstand im Rahmen der Konferenz Medienproduktion „Expansion und Mobilität“ am 7. Dezember 2007. Der Beitrag beschreibt Geschäftsmodelle, Technologien und neue Anwendungen für High Quality Streaming. Neben der Präsentation wurden auch die Medienproduktionen der unterschiedlichen HQ-Mediendienste vorgeführt. Die Mediendienste sind im Rahmen der Forschungsarbeit High Quality Media Services des Studiengangs Communication and Multimedia Design (Fachbereich Elektrotechnik und Informationstechnik) an der Fachhochschule Aachen entstanden. Eine Marktevaluierung der deutschen und niederländischen Märkte, internationale Expertengesprächen sowie ein Prototypen HDMediaservices bilden die Basis der Forschungsarbeit. Die Mediendienste stehen zur Demonstration unter dem Link media.fh-aachen.de bereit. HQ-Mediendienste bedeuten: Gestochen scharfe Bilder in High Definition, volle Klänge in Surround und das über das Internet, wo doch gerade mal die briefmarkengroßen Bilder mit unscharfen Konturen und krätzenden Klängen der heutigen Portale wie YouTube Alltag sind.

T1 - Graph-theoretic resilience analysis of a water distribution system's topology T2 - World Congress on Resilience, Reliability and Asset Management 2019 N2 - Water suppliers are faced with the great challenge of achieving high-quality and, at the same time, low-cost water supply. In practice, the focus is set on the most beneficial maintenance measures and/or capacity adaptations of existing water distribution systems (WDS). Since climatic and demographic influences will pose further challenges in the future, the resilience enhancement of WDS, i.e. the enhancement of their capability to withstand and recover from disturbances, has been in particular focus recently. To assess the resilience of WDS, metrics based on graph theory have been proposed. In this study, a promising approach is applied to assess the resilience of the WDS for a district in a major German City. The conducted analysis provides insight into the process of actively influencing the resilience of WDS KW - Resilience Assessment KW - Graph Theory KW - Water Supply System KW - Case Study Y1 - 2019 N1 - World Congress on Resilience, Reliability and Asset Management, 28-31 July 2019.

Once a trajectory has been found, the next challenge is to accurately and safely follow the precalculated path. The model-predictive controller (MPC) is a common approach for the lateral control of autonomous vehicles. The MPC uses a vehicle dynamics model to predict the future states of the vehicle for a given prediction horizon. However, in order to achieve real-time path control, the computational load is usually large, which leads to short prediction horizons. To deal with the computational load, the control algorithm can be parallelized on the graphics processing unit (GPU). In contrast to the widely used stochastic methods, in this paper we propose a deterministic approach based on grid search. Our approach focuses on systematically discovering the search area with different levels of granularity. To achieve this, we split the optimization algorithm into multiple iterations. The best sequence of each iteration is then used as an initial solution to the next iteration. The granularity increases, resulting in smooth and predictable steering angle sequences. We present a novel GPU-based algorithm and show its accuracy and realtime abilities with a number of real-world experiments.
