Organic Computing
(kassel university press, 2021)
The Organic Computing Doctoral Dissertation Colloquium (OC-DDC) series is part of the Organic Computing (OC) initiative which is steered by a Special Interest Group of the German Society of Computer Science (Gesellschaft für Informatik e.V.). It provides an environment for PhD students who have their research focus within the broader OC community to discuss their PhD project and current trends in the corresponding research areas, including, for instance, research in the context of Autonomic Computing, Self-adaptive ...

Off-Board Car Diagnostics Based on Heterogeneous, Highly Imbalanced and High-Dimensional Data Using Machine Learning Techniques
(kassel university press, 2019)
Data-driven maintenance poses many challenges. Four very important of them, namely coping with a high dimensional and heterogeneos feature space, the highly imbalanced data sets, the Remaining Useful Lifetime (RUL) prediction of monitored parts based on short yet variable length timeseries, and already large but steadily further increasing data set size are identified. Each of the challenges is dealt with in one chapter. Novel techniques are designed, implemented, validated, and compared to existing approaches based ...

Fast Online Control based on Homotopies for Systems subject to Time-Varying Constraints
(kassel university press, 2020)
The integration of intelligent, autonomously acting systems into modern society is a rapidly growing field. After robots are established for simple, recurring processes in industry and everyday life, more complex tasks are of interest which require the systems to consider the environment in their decision making process. In the future, intelligent systems will get access to fields like autonomous driving cars, unmanned aerial vehicle (UAV), manufacturing processes, household, or the assistance to people in need of ...

Organic Computing
(kassel university press, 2023)
Electromobility plays an increasingly important role in the energy transition. Electric vehicle charging poses challenges to the electricity grid due to high peak demand situations. Therefore, it is crucial to leverage the vehicle’s flexibility when charging can be delayed. Conventional charging management systems cannot adapt to frequently changing conditions such as fluctuating renewable energy output, electricity prices and user behavior. In this article, we investigate the application of reinforcement learning ...

Secure Volunteer Computing for Distributed Cryptanalysis
(kassel university press, 2018)
Volunteer computing offers researchers and developers the possibility to distribute their huge computational jobs to the computers of volunteers. So, most of the overall cost for computational power and maintenance is spread across the volunteers. This makes it possible to gain computing resources that otherwise only expensive grids, clusters, or supercomputers offer. Most volunteer computing solutions are based on a client-server model. The server manages the distribution of subjobs to the computers of volunteers, ...

Data Revocation on the Internet
(kassel university press, 2018)
After publishing data on the Internet, the data publisher loses control over it. However, there are several situations where it is desirable to revoke published information. To support this, the European Commission has elaborated the General Data Protection Regulation (GDPR). In particular, this regulation requires that controllers must delete data on user's demand. However, the data might already have been copied by third parties. Therefore, Article 17 of the GDPR includes the regulation that a controller must also ...

Distributed Model Predictive Control with Event-Based Communication
(kassel university press, 2015)
In this thesis, several algorithms for distributed model predictive control over digital communication networks with parallel computation are developed and analyzed. Distributed control aims at efficiently controlling large scale dynamical systems which consist of interconnected dynamical systems by means of communicating local controllers. Such distributed control problems arise in applications such as chemical processes, formation control, and control of power grids. In distributed model predictive control the ...

Modularization of Services
(kassel university press, 2016)
The design and provision of telemedical services which are both, efficient and customer-centric, constitute a huge challenge in the promising field of telemedicine. This dissertation presents an adequate solution. It outlines a systematic approach for the modularization of telemedical services: the SMART method.Following a design science research approach, this method was iteratively designed and evaluated. Thereby, the three overarching research questions could be answered successfully. They address the requirements ...

Netzpolitik – Entsteht ein Politikfeld für Digitalpolitik?
(kassel university press, 2017)
Wir leben im digitalen Zeitalter. Es gibt fast keinen Bereich der Gesellschaft, der Wirtschaft oder der Politik, den die Digitalisierung nicht auf irgendeine Art und Weise betrifft. Die Entwicklungen verlaufen dabei jedoch nicht vorherbestimmt und technikdeterminiert. Vielmehr bieten sie eine Gestaltungsperspektive und damit auch gesellschaftliche und politische Gestaltungaufgabe. In den letzten Jahren hat sich für die Bearbeitung der mit der Digitalisierung verbundenen Themenfelder auf der politischen Ebene der ...

Run-time Reconfigurable Constant Multiplication on Field Programmable Gate Arrays
(kassel university press, 2017)
This book addresses the question how run-time reconfigurable constant multipliers (RCMs) can be efficiently implemented on field programmable gate arrays (FPGAs). RCMs calculate the multiplication of an input number by one out of several constants which can be selected during run-time. This is important as constant multiplication is an essential operation in digital signalprocessing (DSP) applications. The evaluation of RCMs is done by considering reconfiguration using reconfigurable look-up tables (LUTs),reconfiguration ...
