- KonferenzbeitragEnerGeoPlan – Eine domänenspezifische Sprache zur Formalisierung von Raumplanungsregeln für GIS-Systeme(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Schütte, Steffen; Knies, JürgenDer rasant wachsende Ausbau Erneuerbarer Energien unterliegt einer stetig wachsenden Zahl von gesetzlichen Vorgaben, deren Einhaltung zu immer komplexeren Planungsprozessen führt. Neben diesen Vorgaben rückt auch das Stromnetz als Flaschenhals“ immer mehr in den Vordergrund. Das Projekt EnerGeoPlan hat daher ” zum Ziel, mit Hilfe eines kombinierten Einsatzes von Netzanalyse und Geografischen Informationssystemen (GIS) eine Netzund Anlagenplanung zu ermöglichen, die beide Aspekte berücksichtigt. In diesem Beitrag wird dabei eine domänenspezifische Sprache vorgestellt, welche die Formalisierung und automatische Verarbeitung relevanter Planungsregeln durch das GIS überhaupt erst ermöglicht.
- KonferenzbeitragMarking Menus im sicherheitskritischen mobilen Kontext am Beispiel des Rettungsdienstes(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Mentler, Tilo; Kutschke, René; Herczeg, Michael; Kindsmüller, Martin ChristofRettungsdienste sind ein wichtiger Bestandteil der Gefahrenabwehr und der Gesundheitsvorsorge. Die Arbeit des Rettungsfachpersonals und der Notärzte ist geprägt von zahlreichen täglichen Routineeinsätzen (Krankentransporte, individualmedizinische Notfälle) einerseits und außergewöhnlichen Einsatzlagen bei einem Massenanfall von Verletzten (MANV) andererseits. Zur Dokumentation relevanter Patienten- und Behandlungsdaten werden gegenwärtig in der Regel noch zahlreiche Papierformulare eingesetzt. Mobile computerbasierte Werkzeuge sind im Regeldienst vereinzelt, für den MANV bislang nicht etabliert. Zur Gestaltung einer gebrauchstauglichen Lösung, deren Benutzung bei der Erledigung von Routineaufgaben effizient und unter extremen Bedingung effektiv ist, werden in diesem Beitrag erweiterte Radialmenüs (Marking Menus) im Zusammenhang mit stiftbasierter Touch-Steuerung als potenzielle Alternative zu etablierten Bedienkonzepten vorgestellt und exemplarisch auf den rettungsdienstlichen Kontext angewendet. Die gebrauchstaugliche Gestaltung wird abschließend durch eine formative Evaluation untersucht, aus der weitere Entwicklungspotentiale abgeleitet werden.
- KonferenzbeitragSelf-reconfigurable control architecture for complex robots(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Hartmann, Jan; Stechele, Walter; Maehle, ErikAdvanced robot systems need to carry out increasingly complex task sets. However, they are typically optimized to a very restricted set of tasks and environments to solve demanding problems. This work will therefore propose a self-reconfigurable software and hardware architecture in order to enable the dynamic optimization of a robot system depending on the current situation, i.e. the current task, robot state, and environment. The proposed framework is based on organic computing principles and unsupervised machine learning techniques. It further uses dynamically reconfigurable Field Programmable Gate Arrays (FPGA) as hardware accelerators.

- KonferenzbeitragTowards multi-party evolution of social software(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Poetzsch-Heffter, Arnd; Paech, Barbara
- KonferenzbeitragPolymorphic computers – virtualization of instruction set and microarchitecture(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Hochberger, ChristianToday, virtualization is often discussed on rather high abstraction levels (infrastructure, platform, software as a service). In contrast, in this talk the AMI- DAR processor concept [GH05] will be presented, which allows virtualization on the instruction set level as well as on the microarchitectural level. Running different instruction sets on the same hardware and microarchitecture is not a new idea. Particularly, in the early days of microprogrammed machines, it was quite common to run different application specific instruction sets on the same machine. After microprogramming was abandoned due to its performance issues, in- struction set architectures (ISA) became rather static. The proposed AMIDAR concept allows changeable instruction sets, yet provides execution efficiency close to modern pipelined processors. Candidate ISAs for this approach are not typical RISC ISAs but rather popular abstract ISAs like Java Bytecode, .NET intermediate language or the LLVM bitcode. Similar to software execution environments for these ISAs, AMI- DAR processors will also optimize the execution of instruction sequences, but on the hardware level. Varying the amount and selection of microarchitectural components is also a well developed technique. It is used to build different processor variants for the same ISA, but targeting very different design goals (energy efficiency, performance, throughput). In almost any processor architecture these selections are made before the processor is designed. In AMIDAR processors, these choices are made at runtime and dynamically depending on the characteristic of the running application. This can be seen as a virtualization of hardware resources, where the processor decides itself how to make best use of the available resources. To this end, a reconfigurable fabric can be included in AMIDAR processors, for which the configuration is created at runtime [DH11]. The talk presents achievements, current status and an outlook of the AMIDAR project.
- KonferenzbeitragSAP HANA: In-memory technology as business enabler featuring product cost prediction simulation(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Sieberg, Rolf P. B.SAP HANA is an in-memory platform for real-time analytics and applications. High data compression in columnar storage, massive parallel processing and in-memory computing enable extremely fast response times even for big data volumes. Thus the door is open for a wide range of new business processes and analytics. One example for an interesting area of application is Product Cost Prediction and Simulation. Starting out from past and current product costs - as stored typically in an ERP system - one can predict cost changes, margin impacts and procurement requirements for potential future market conditions. Because of HANA’s calculation speed, on-the-fly simulations and what-if analyses can be carried out. Such investigations are particularly interesting for the consumer products industry: Here costs of goods sold are usually highly dependent on prices for commodities and raw materials. Calculating the impact of a commodity such as oil on the total cost and margin of an entire company is most often quite complex - also because of the high amount of data to be typically taken into account. With SAP HANA such computations can be carried out within seconds, allowing the simulation and exploration of many different future scenarios.
- KonferenzbeitragInterdisziplinary development patterns from the use case: Support-U(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Voigtmann, Christian; Söllner, Matthias; Wilhelm, Daniel; David, Klaus; Leimeister, Jan MarcoSoftware development has proven to be a challenge. To address this challenge, there are quite many interesting approaches how to develop software - starting from the waterfall approach, up to recently quite popular agile software development techniques. Another already some years old approach was described by the Gang of Four and proposes the usage of design patterns to provide a general reusable solution to commonly occurring problems in software development. Although design patterns have been around for a long time, their usability is still promising. To the best of our knowledge ”interdisciplinary patterns” to address challenges in the development of context aware application in ubiquitous environments have not been described in literature so far. Hence, this paper proposes and also evaluates concrete interdisciplinary software development patterns. To provide an application example the proposed patterns are used to address two use cases that commonly occur in the development process of context aware applications: providing transparency to the user and ensuring a user's self-determination. For the demonstration of the patterns Support-U a context aware application that provides elderly people to live autonomously is used.
- KonferenzbeitragInvestigating quality raters' performance using interface evaluation methods(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Röder, Michael; Speicher, Maximilian; Usbeck, Ricardo
- KonferenzbeitragEncapsulated models for reasoning and decision support(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Čače, Ivana; Meyer, John-Jules Ch.; Pieterman, C.R.C.; Valk, G.D.In this paper we show how knowledge from the medical domain can be incorporated in classification in a way that improves the transparency of classification (the 'why'), and makes the classification less dependent on both the particular data set used for training and on peculiarities of the classification algorithm. We compare a decision tree incorporating a domain model with a tree built directly from the same data.
