People quickly and efficiently take in visually processed information. The processing of data of any kind is therefore an important and heavily researched area in data science and all its surrounding fields. The aim is to simplify complex information as much as possible so that the core information can be transported as simply and clearly as possib...
Künstliche neuronale Netze sind eines der aktuell vielversprechendsten Gebiete im Bereich der Künstlichen Intelligenz und des maschinellen Lernens. Sie finden in immer mehr Bereichen Anwendung und versprechen damit, einen wesentlichen Beitrag im Zuge der Digitalisierung in Unternehmen zu leisten. Künstliche neuronale Netze sind dabei ein Ansatz, au...
Menschen nehmen visuell aufbereitete Informationen schnell und effizient wahr. Die Aufbereitung von Daten jeder Art ist daher ein wichtiges und stark beforschtes Gebiet in der Data Science und all ihren umliegenden Feldern. Dabei gilt es, komplexe Informationen so weit zu vereinfachen, dass ohne signifikanten Sinnverlust die Kerninformationen mögli...
In this paper we describe our approach on pro-tecting user privacy in smart environments, particularly smart homes, which we call eHomes. These are environments with devices such as sensors, computational units, actors, which are seamlessly integrated in the environment, and objects we use in our everyday life. In order to provide more convenience...
In future smart homes functionality will be provided to the inhabitants by software services decoupled from the underlying hardware devices. While this will enhance flexibility and will allow to provide cross-functionalities across multiple devices it will also lead to resource conflicts. Future devices will provide basic functionalities which are...

Smart environments are subject to intensive aca-demic and industrial research. Many of these research projects deal with challenges such as heterogeneity, per-sonalization and context-awareness. However, most of them assume smart environments to be insular places. Considering users visiting different environments in daily life, this assumption beco...
In many areas of computer science ontologies become more and more important. The use of ontologies for domain modeling often brings up the issue of ontology integration. The task of merging several ontologies, covering specific subdomains, into one unified ontology has to be solved. Many approaches for ontology integration aim at automating the pro...
Software reuse and hardware integration are key factors to offer flexible, low-cost smart environments. Until now, we have
been using a static process called the SCD-process to allow a tool-supported realization of such smart environments. The SCD-process
is comprised of three different phases: specification, configuration, and deployment. As an in...

To develop a market for low-cost Smart Homes reuse of ready-made software components is an essential requirement to reduce the development costs of such systems. Users will run services from a variety of different software producers, which will lead to a heterogeneous service environment. Therefore one of the major challenges is to guarantee intero...
Ontologies are often used to define concepts of certain application domains. Using knowledge from several different subdomains
then requires the integration of the defined ontologies. Since ontology integration is a difficult task, there is a need for
adequate tool support. In the ConDes project, we developed a knowledge-based support for the conce...
Smart environments are pervasive systems that comprise integrable net-aware devices. This way, intelligent services can offer complex functionalities across multiple devices. Smart home environments, also called eHomes, constitute already an important research area. However, to build a real elome is associated with high effort and financial costs....
The conceptual design phase at the beginning of the building construction process is not adequately supported by any CAD-tool. Conceptual design support needs regarding two aspects: first, the architect must be able to develop conceptual sketches that provide abstraction from constructive details. Second, conceptually relevant knowledge should be a...
New developments and decreasing costs of electronic appliances enable the realization of pervasive systems in our daily environment. In our work, we focus on eHome systems. The cost-intensive repetitive development process for every new eHome environment is one of the major problems preventing their widespread use. So, we transformed the repetitive...
Currently, the conceptual design phase is not adequately supported by any CAD tool. Neither the support while elaborating conceptual sketches, nor the automatic proof of correctness with respect to effective restrictions is currently provided by any commercial tool. To enable domain experts to store the common as well as their personal domain knowl...
