Due to the rising energy prices energy efficient heating systems become more and more attractive. Next to the energy consumption the comfort is a very
important criterion. Conditioned by these requirements the number of panel heating systems will increase in the future. To comply with the customer request
infrared (IR) radiation is suitable, because of the reduced dust emergence and noise emission in comparison to standard heaters. Infrared heating systems are
beneficial to health and create a “feel-good” climate. Based on these aspects a ZIM-supported project was initiated to develop an innovative textile heating
system using carbon nanotubes (CNT), which emit infrared radiation

Sind digitale Währungen wie Bitcoin nur eine „digitale Phase“ oder werden sie in der Zukunft einen beachtenswerten Teil der globalen Finanztransaktionen bestimmen? Welche Anwendungsszenarien der Technologien sind denkbar? Und wie können die bestehenden Hürden überwunden werden um Peer-to-Peer-Systeme im Finanzbereich nachhaltig zu etablieren? Eine aktuelle Studie versucht diese Fragen zu beantworten.

In der Betriebswirtschaft, auch im Bereich des Marketings oder der Medienwirtschaft, scheint die betriebliche Kommunikationspolitik im Marketing-Mix unter den „4 P“ oft immer noch eine Randstellung einzunehmen. Zwar ist der „Vierklang“ des Marketing-Mix in den meisten Standardwerken inzwischen Konsens. In vielen Lehrbüchern wird aber etwa der Bereich der Mediaplanung wie auch der kommunikationspolitische Aspekt der Zielgruppendefinition zu Gunsten einer eher Produkt- und Leistungsportfolio bezogenen Sichtweise – wie noch zu zeigen sein wird – oft vernachlässigt. Auf noch dünnerem Eis bewegt man sich, wenn man diese Themenfelder auf die digitale Welt bezieht. Auch heute noch, fast 25 Jahre nach der ersten breit zugänglichen Publikation im „World Wide Web“, wird Digitale Kommunikation in den meisten klassischen Lehr- und Grundlagenwerken nur als Sparten- oder Randthema behandelt und eher vermeintlich spezifischen Publikationen zum „Online Marketing“ überlassen. Das erscheint verwunderlich, wenn man das alltägliche Phänomen der Digitalisierung und das dadurch ermöglichte Aufkommen von Sozialen Netzwerken oder die flächendeckenden Verbreitung von Smartphones sowie ihre Auswirkung auf den Stellenwert von Informationskonsum und Kommunikation betrachtet.

The paper presents results from an empirical study about the use of a single sign-on (SSO) system in an integrated open source system landscape for supporting team collaboration. A portal solution, enterprise content man-agement system, groupware, business process management and enterprise search engine are used. The investigation shows that although it is easy to achieve SSO with the Web-based user interfaces of the information systems used, none of the systems was prepared to pass authentication tokens to the API of an integrated system or accept SSO tokens instead of username / password pairs for authentication against the API respectively. Different al-ternatives for achieving the desired functionality are presented and a recom-mendation for improvement of the affected information systems is derived.

Usually, knowledge workers are said to not benefit from business process management (BPM) systems, since their main tasks are weakly structured and not representable by a workflow. However, not all of their tasks are equally weak structured, and with adaptive case management (ACM) solutions, a new category of tools came up to support those processes, even if they are weakly structured. This paper introduces an approach to support the creation of cases for ACM engines by mining activities from an activity stream and suggesting tasks that a knowledge worker can use to create a case. Furthermore, the approach supports maturing of the case towards a workflow by detecting repeating sequences in the execution of tasks and suggesting sub processes for the case which is possible with the case management model and notation (CMMN) together with the business process model and notation (BPMN). To allow for further enhancement of the cases, the ACM solution is extended with social collaboration features, so that people working on the case can comment and rate single tasks. The goal is to show that it is possible to establish ties from social activities and Web 2.0 to ACM and BPM. The presented solution uses a graph database as a basis for activity mining.

This paper presents a concept for integrating social media functionality into existing collaboration systems and using this functionality to also integrate the collaboration systems themselves. Social media functionality is used in the areas contents, contacts and communication to support knowledge sharing and knowledge maturing. Using a micro-service architecture, our concept allows for social media functionality in every collaboration system. Users benefit from a better overview due to a central activity stream with entries of all systems, as well as a consistent UI. They don’t have to chose a certain tool but can use the desired functionality like rating, tagging or commenting everywhere. We further provide information about a technical implementation of the concept with popular open source software like Liferay and OpenXchange.

After the human-oriented, technology-oriented (documents), process-oriented and social KM phases, KM support now needs integration of those beneficial technologies instead of hyping one and neglecting the other. This paper proposes a highly modular yet integrated approach to support KM instruments and shows how this approach is implemented based on open source collaboration systems in the SCHub project which represents an enterprise knowledge infrastructure (EKI). The applicability is shown with three KM instruments in the areas people, contents and processes. Social media and search functionality serve as an integration factor for the EKI.

Docker provides a good basis to run composite applications in the cloud, especially if those are not cloud- aware, or cloud-native. However, Docker concentrates on managing containers on one host, but SaaS provi- ders need a container management solution for multiple hosts. Therefore, a number of tools emerged that claim to solve the problem. This paper classifies the solutions, maps them to requirements from a case study and identifies gaps and integration requirements. We conclude that the Docker ecosystem could help moving from IaaS and PaaS solutions towards a runtime environment for SaaS applications, but needs consolidation.
