Cool Navigate researches strategies for the development and execution of adaptive Web applications in mobile scenarios. Depending on properties of the client devices and mobile communication facilities, we strive for an energy-optimized application use. A client-server distribution of application components is performed depending on the energy state of the mobile device. In case of a high battery charge state, resource-intensive parts of the application can be run directly on the mobile client, which may result in an increased ease of use. If the battery level is low, the client is operating in power save mode, whereas more computing power is delivered by the server to execute application components.

The project aims to reduce the energy consumption of complex IT systems through intelligent software controlling. Therefore, we investigate, to which extent the use of adaptive software at application and system level can lead to an energy optimized operation of the underlying hardware infrastructure.

The CRUISe project focuses on the development of novel concepts for the model-driven development and deployment of adaptive, composite web applications. Its central idea is to support a "universal composition" – the service-oriented composition of applications from uniform components providing data, business logic and user interface parts. Additionally, CRUISe supports the context-aware discovery and configuration of these components as well as the dynamic adaptation of the composition at runtime with respect to context changes.

The project DEMISA addresses the model-driven development process from business processes models to composite mashup applications. For a better alignment of business applications to business processes this project extends the description of mashup components with task-oriented features in order to suggest components and mashups during the authoring of process-oriented applications. Further an integrative runtime environment for mashups and processes and appropriate development tools are needed.

In the last years the spontaneous teamwork, the so called informal collaboration, got into the focus of the computer supported cooperative work (CSCW) research area. Thereby, it is investigated how this form of collaboration could be supported by using mobile devices, because they provide the advantage of a location- and time-independent use. In this context the research projekt DoCUMA is concerned with the possibilities of the static and dynamic distribution and composition of application components. In doing so, it should be clarified how distribution of components to different platforms, dependent on context properties, can be described in the composition model of an application.

The EDYRA research group is project cooperation of the Chair for Multimedia Technology and the Database Technology Group at the TU Dresden Department of Computer Science. It is part of the research cluster ResUbic Lab Dresden. We aim at the development of composite, service oriented, and adaptive rich internet applications for business applications, as well as, personal application scenarios. Funding is provided by the Free State of Saxony and the European Union within the European Social Funds (ESF) program.

The project HSM addresses serveral research questions regarding problems of document archiving and long term archiving of various multimedia formats. For example, this concerns the software architecture, interfaces and management algorithms, different document formats for long time archiving (also interactive documents), questions regarding the digital rights management of specific information, aspects of data security, cryptography and key management, but also research questions about metadata management and extraction of semantic data of documents, as also problems of the usability of client- and serversided applications.

As a DFG project, Hyperadapt investigates well-formed and controlled multi-staged aspect-oriented adaption in the context of hypermedia web applications. The project builds up on experiences gathered in the projects AMACONT and Reuseware.

The research project K-IMM deals with the generation and modelling of semantic descriptions for multimedia documents and their context. Aim of the project is to support creation, storage and maintenance of individual knowledge to enable semantic media management.

Mefisto is a lead project of the German Federal Ministry of Education and Research in the framework the program IKT 2020. In the context of constructional informatics, its goal is the support of the management of construction projects with the help of a management information system. Besides numerous other research questions, the development of a context-aware, intelligent information visualizations framework is a main task which the chair of multimedia techniques attends. With the use of the semantics of the data, the domain, and the task as well as with the context of the user and his platform it’s the objective to visualize the data in a suitable manner.

TODO

The objective of this research project is the modeling of news and its media object using semantic technologies. Thus, it will be possible to automatically identify current topics within all the news items as well as to highlight them in a NewsRoom application.
