The capabilities of autonomous robots are increasing which is a reason for research progress in the last years. An increasing number of robotic scenarios are becoming more viable in various domains for example, mowing, harvesting, warehouse robots. But autonomous mobile robots need more than the ability to navigate through their world, and manipulate objects. Even in teams of robots, a structured plan for each team member is necessary. Planning becomes a more important task. Furthermore, the environment can ...

The primary objective of Mobile Cloud Computing (MCC) is the support of resource-constrained mobile devices by means of Cloud or nearby computing resources. In general, this is achieved by outsourcing or offloading computational intensive tasks of mobile applications. This allows, for instance, to virtually extend the processing power of mobile devices and, indirectly, to save battery life. In case remote resources are not available or the communication link is broken, still a local execution is possible. The ...

Enterprise-Resource-Planning-Systeme (ERP-Systeme) bilden für die meisten mittleren und großen Unternehmen einen essentiellen Bestandteil ihrer IT-Landschaft zur Verwaltung von Geschäftsdaten und Geschäftsprozessen. Geschäftsdaten werden in ERP-Systemen in Form von Geschäftsobjekten abgebildet. Ein Geschäftsobjekt kann mehrere Attribute enthalten und über Assoziationen zu anderen Geschäftsobjekten einen Geschäftsobjektgraphen aufspannen. Existierende Schnittstellen ermöglichen die Abfrage von Geschäftsobjekten, ...

Mit der steigenden Komplexität von IT-Systemen wird auch die Verwaltung dieser Systeme komplexer. Den Fragestellungen, die sich durch diese Komplexität auf der Seite des Betriebs und der Überwachung von IT-Systemen stellen, wird durch integriertes und automatisiertes IT-Management begegnet, indem auch implizite Zusammenhänge zwischen Aspekten aus unterschiedlichen Sichten auf die Systeme berücksichtigt werden, sowie die weitgehende Eliminierung des manuellen Anteils bei Überwachung und Pflege der Systeme angestrebt ...

Das erfolgreiche Agieren von Multiagentensystemen (MAS) setzt eine umfangreiche und hochwertige Wissensbasis voraus. Die Wissensbasis umfasst die von einem Agenten benötigten Informationen, welche durch die Verarbeitung von Sensorinformationen erzeugt werden. Die Anpassung der Informationsverarbeitung an die Einsatzdomäne ermöglicht es, die Qualität der Wissensbasis zu gewährleisten und so die Leistung des MAS zu steigern. Aktuelle Middleware-Systeme unterstützen die Integration von gängigen Methoden und Verfahren ...

Today, robots are used in nearly every type of automated manufacturing and assembly process. Robot installations typically apply static actuator systems in clearly structured environments. These systems show impressive abilities in speed and accuracy for repetitive manipulation tasks. Future automation applications, however, require an increasing level of flexibility, where classical systems reach their physical limits. As a reaction, robots become mobile, intelligent and cooperative. These new characteristics, ...

In the vision of Mark Weiser on ubiquitous computing, computers are disappearing from the focus of the users and are seamlessly interacting with other computers and users in order to provide information and services. This shift of computers away from direct computer interaction requires another way of applications to interact without bothering the user. Context is the information which can be used to characterize the situation of persons, locations, or other objects relevant for the applications. Context-aware ...

Self-adaptive software provides a profound solution for adapting applications to changing contexts in dynamic and heterogeneous environments. Having emerged from Autonomic Computing, it incorporates fully autonomous decision making based on predefined structural and behavioural models. The most common approach for architectural runtime adaptation is the MAPE-K adaptation loop implementing an external adaptation manager without manual user control. However, it has turned out that adaptation behaviour lacks ...

Context awareness, dynamic reconfiguration at runtime and heterogeneity are key characteristics of future distributed systems, particularly in ubiquitous and mobile computing scenarios. The main contributions of this dissertation are theoretical as well as architectural concepts facilitating information exchange and fusion in heterogeneous and dynamic distributed environments. Our main focus is on bridging the heterogeneity issues and, at the same time, considering uncertain, imprecise and unreliable sensor information ...

In the past years, we could observe a significant amount of new robotic systems in science, industry, and everyday life. To reduce the complexity of these systems, the industry constructs robots that are designated for the execution of a specific task such as vacuum cleaning, autonomous driving, observation, or transportation operations. As a result, such robotic systems need to combine their capabilities to accomplish complex tasks that exceed the abilities of individual robots. However, to achieve emergent cooperative ...
