In this presentation the audience will be: (a) introduced to the aims and objectives of the DBTechNet initiative, (b) briefed on the DBTech EXT virtual laboratory workshops (VLW), i.e. the educational and training (E&T) content which is freely available over the internet and includes vendor-neutral hands-on laboratory training sessions on key database technology topics, and (c) informed on some of the practical problems encountered and the way they have been addressed. Last but not least, the audience will be invited to consider incorporating some or all of the DBTech EXT VLW content into their higher education (HE), vocational education and training (VET), and/or lifelong learning/training type course curricula. This will come at no cost and no commitment on behalf of the teacher/trainer; the latter is only expected to provide his/her feedback on the pedagogical value and the quality of the E&T content received/used.
Das Internet gewinnt für das Marketing zunehmend an Bedeutung. Dabei liegt der Fokus auf sogenannten Social-Media-Anwendungen wie Facebook, Twitter oder XING. Für Unternehmen stellt sich die Frage, ob das veränderte Mediennutzungsverhalten der Kunden eine neue Marketinglogik induziert. Eine aktuelle Untersuchung gibt Einblicke in die Chancen und Risiken, Anwendungsbedingungen und Kontextfaktoren für die Nutzung von Social Media im Marketing.
Der Beitrag gibt einen Überblick zum Stand der Vertrauensforschung in Marketing und Vertrieb. Dabei ist Vertrauen als Gegenstand der Forschung innerhalb des Relationship Marketing Ansatzes sehr gut etabliert. Bei der Definition des Vertrauensbegriffs stützt sich das Marketing auf die Erkenntnisse der sozialwirtschaftlichen Nachbardisziplinen. Soweit Kunden ihren Anbietern vertrauen, gehen sie grundsätzlich ein Risiko ein und machen sich hierdurch angreifbar. Man vertraut in einen Anbieter, ohne vorab genau zu wissen, ob das gewünschte Resultat einer Kooperation mit Sicherheit eintritt. Dies gilt umgekehrt auch für den Anbieter, der zum Teil erhebliche Vorinvestitionen tätigen muss, ohne vorab zu wissen, ob tatsächlich eine Geschäftsbeziehung mit einem Kunden entsteht. Vertrauen ist daher v.a. in komplexen und langfristigen Beziehungen zwischen Anbietern und Kunden eine wesentliche Ressource. Entsprechend thematisiert der Beitrag die Bedingungen und Auswirkungen von Vertrauen auf unterschiedlichen Ebenen. Dabei dominiert in Marketing und Vertrieb noch immer eine interpersonale Perspektive. Die Potentiale organisationaler Beziehungsstrategien sind zum gegenwärtigen Zeitpunkt eher schwach beleuchtet, jedoch greift der Beitrag einige Trends für die weitere Ausrichtung der Vertrauensforschung auf, die zukünftig stärker an Bedeutung gewinnen werden. Dabei ist grundsätzlich davon auszugehen, dass bei zunehmend volatilen Rahmenbedingungen das Interesse an Vertrauensfragen auch in Marketing und Vertrieb weiter zunimmt.
Der vorliegende Artikel beleuchtet die grundsätzlichen Möglichkeiten der Integration von Funktionalitäten der sozialen Medien in Unternehmen. Darauf aufbauend wird Social Commerce als zentraler Gegenstand der Unternehmensführung hergeleitet. Dabei stehen der kundenseitige Kaufprozess und dessen Schnittstellen zu Kommunikationsinstrumenten des Social Webs im Vordergrund. Gezeigt wird die Beeinflussung des individuellen Kaufprozesses durch Social Media. Diese Wirkungsdynamiken sind nachfolgend die Grundlage für die Deskription von möglichen strategischen Einsatzfeldern und Bereichen des Social Commerce in der Unternehmensführung.
Der Kundenservice bietet für das Marketing umfangreiche Ansätze zur Differenzierung. Dabei zahlen positive Serviceerlebnisse der Kunden auf unterschiedliche Marketingziele ein. Durch Social Media stehen darüber hinaus neue Möglichkeiten für den Servicedialog zur Verfügung. Der vorliegende Beitrag beschreibt die Umsetzung dieser Möglichkeiten bei der Telekom Deutschland GmbH.
The use of Wireless Sensor and Actuator Networks (WSAN) as an enabling technology for Cyber-Physical Systems has increased significantly in recent past. The challenges that arise in different application areas of Cyber- Physical Systems, in general, and in WSAN in particular, are getting the attention of academia and industry both. Since reliability issues for message delivery in wireless communication are of critical importance for certain safety related applications, it is one of the areas that has received significant focus in the research community. Additionally, the diverse needs of different applications put different demands on the lower layers in the protocol stack, thus necessitating such mechanisms in place in the lower layers which enable them to dynamically adapt. Another major issue in the realization of networked wirelessly communicating cyber-physical systems, in general, and WSAN, in particular, is the lack of approaches that tackle the reliability, configurability and application awareness issues together. One could consider tackling these issues in isolation. However, the interplay between these issues create such challenges that make the application developers spend more time on meeting these challenges, and that too not in very optimal ways, than spending their time on solving the problems related to the application being developed. Starting from some fundamental concepts, general issues and problems in cyber-physical systems, this chapter discusses such issues like energy-efficiency, application and channel-awareness for networked wirelessly communicating cyber-physical systems. Additionally, the chapter describes a middleware approach called CEACH, which is an acronym for Configurable, Energy-efficient, Application- and Channel-aware Clustering based middleware service for cyber-physical systems. The state of-the art in the area of cyberphysical systems with a special focus on communication reliability, configurability, application- and channel-awareness is described in the chapter. The chapter also describes how these features have been considered in the CEACH approach. Important node level and network level characteristics and their significance vis-àvis the design of applications for cyber physical systems is also discussed. The issue of adaptively controlling the impact of these factors vis-à-vis the application demands and network conditions is also discussed. The chapter also includes a description of Fuzzy-CEACH which is an extension of CEACH middleware service and which uses fuzzy logic principles. The fuzzy descriptors used in different stages of Fuzzy-CEACH have also been described. The fuzzy inference engine used in the Fuzzy-CEACH cluster head election process is described in detail. The Rule-Bases used by fuzzy inference engine in different stages of Fuzzy-CEACH is also included to show an insightful description of the protocol. The chapter also discusses in detail the experimental results validating the authenticity of the presented concepts in the CEACH approach. The applicability of the CEACH middleware service in different application scenarios in the domain of cyberphysical systems is also discussed. The chapter concludes by shedding light on the Publish-Subscribe mechanisms in distributed event-based systems and showing how they can make use of the CEACH middleware to reliably communicate detected events to the event-consumers or the actuators if the WSAN is modeled as a distributed event-based system.
Stent graft visualization and planning tool for endovascular surgery using finite element analysis
(2014)
Purpose: A new approach to optimize stent graft selection for endovascular aortic repair is the use of finite element analysis. Once the finite element model is created and solved, a software module is needed to view the simulation results in the clinical work environment. A new tool for Interpretation of simulation results, named Medical Postprocessor, that enables comparison of different stent graft configurations and products was designed, implemented and tested. Methods Aortic endovascular stent graft ring forces and sealing states in the vessel landing zone of three different configurations were provided in a surgical planning software using the Medical Imaging Interaction Tool Kit (MITK) Software system. For data interpretation, software modules for 2D and 3D presentations were implemented. Ten surgeons evaluated the software features of the Medical Postprocessor. These surgeons performed usability tests and answered questionnaires based on their experience with the system.
Results: The Medical Postprocessor visualization system enabled vascular surgeons to determine the configuration with the highest overall fixation force in 16 ± 6 s, best proximal sealing in 56±24 s and highest proximal fixation force in 38 ± 12 s. The majority considered the multiformat data provided helpful and found the Medical Postprocessor to be an efficient decision support system for stent graft selection. The evaluation of the user interface results in an ISONORMconform user interface (113.5 points).
Conclusion: The Medical Postprocessor visualization Software tool for analyzing stent graft properties was evaluated by vascular surgeons. The results show that the software can assist the interpretation of simulation results to optimize stent graft configuration and sizing.
Intra-operative fluoroscopy-guided assistance system for transcatheter aortic valve implantation
(2014)
A new surgical assistance system has been developed to assist the correct positioning of the AVP during transapical TAVI. The developed assistance system automatically defines the target area for implanting the AVP under live 2-D fluoroscopy guidance. Moreover, this surgical assistance system works with low levels of contrast agent for the final deployment of AVP, reducing therefore long-term negative effects, such as renal failure in the elderly and high-risk patients.
A configuration-management-database driven approach for fabric-process specification and automation
(2014)
In this paper we describe an approach that integrates a Configuration- Management-Database into fabric-process specification and automation in order to consider different conditions regarding to cloud-services. By implementing our approach, the complexity of fabric processes gets reduced. We developed a prototype by using formal prototyping principles as research methods and integrated the Configuration-Management-Database Command into the Workflow- Management-System Activiti. We used this prototype to evaluate our approach. We implemented three different fabric-processes and show that by using our approach the complexity of these three fabric-processes gets reduced.
Stress is recognized as a factor of predominant disease and in the future the costs for treatment will increase. The presented approach tries to detect stress in a very basic and easy to implement way, so that the cost for the device and effort to wear it remain low. The user should benefit from the fact that the system offers an easy interface reporting the status of his body in real time. In parallel, the system provides interfaces to pass the obtained data forward for further processing and (professional) analyses, in case the user agrees. The system is designed to be used in every day’s activities and it is not restricted to laboratory use or environments. The implementation of the enhanced prototype shows that the detection of stress and the reporting can be managed using correlation plots and automatic pattern recognition even on a very light weighted microcontroller platform.
