This interdisciplinary community is fairly new, it is still not well integrated and is therefore confronted with differing perspectives, processes, methods, tools, vocabularies, and standards. We present a Common Body of Knowledge (CBK) to overcome the aforementioned problems. We capture use cases from research and practice to derive requirements for the CBK. Our CBK collects, integrates, and structures knowledge from the different disciplines based on an ontology that allows one to semantically enrich content to be able to query the CBK. The CBK heavily relies on user participation, making use of the Semantic MediaWiki as a platform to support collaborative writing. The ontology is complemented by a conceptual framework, consisting of concepts to structure the knowledge and to provide access to it, and a means to build a common terminology. We also present organizational factors covering dissemination and quality assurance.}, language = {en} } @inproceedings{JahrBatosSimetal.2012, author = {Jahr, Andreas and Batos, Andrej and Sim, Hunn and Villena Mart{\´i}nez, Jose David}, title = {A New Approach for Measuring the Wear Resistance of Cutter Blades}, series = {International Conference of Agricultural Engineering - CIGR-AgEng2012, Valencia/Spanien, 8.-12.07.2012}, booktitle = {International Conference of Agricultural Engineering - CIGR-AgEng2012, Valencia/Spanien, 8.-12.07.2012}, year = {2012}, language = {en} } @inproceedings{ZhaoMeuterNunnetal.2012, author = {Zhao, Kun and Meuter, Mirko and Nunn, Christian and Muller, Dennis and Muller-Schneiders, Stefan and Pauli, Josef}, title = {A novel multi-lane detection and tracking system}, series = {2012 IEEE Intelligent Vehicles Symposium (IV)}, booktitle = {2012 IEEE Intelligent Vehicles Symposium (IV)}, publisher = {IEEE}, isbn = {978-1-4673-2119-8}, doi = {10.1109/IVS.2012.6232168}, pages = {1084 -- 1089}, year = {2012}, language = {en} } @inproceedings{RuessVarduhnRanketal.2012, author = {Ruess, Martin and Varduhn, Vasco and Rank, Ernst and Yosibash, Zohar}, title = {A Parallel High-Order Fictitious Domain Approach for Biomechanical Applications}, series = {11th International Symposium on Parallel and Distributed Computing (ISPDC), 2012 : 25 - 29 June 2012, Munich, Germany ; proceedings}, booktitle = {11th International Symposium on Parallel and Distributed Computing (ISPDC), 2012 : 25 - 29 June 2012, Munich, Germany ; proceedings}, editor = {Bader, Michael}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-4673-2599-8}, doi = {10.1109/ISPDC.2012.45}, pages = {279 -- 285}, year = {2012}, language = {en} } @inproceedings{BeckersFassbenderKuesteretal.2012, author = {Beckers, Kristian and Faßbender, Stephan and K{\"u}ster, Jan-Christoph and Schmidt, Holger}, title = {A Pattern-Based Method for Identifying and Analyzing Laws}, series = {Requirements Engineering: Foundation for Software Quality: 18th International Working Conference, REFSQ 2012, Essen, Germany, March 19-22, 2012.

Because of ash plume forecasts of the VAAC London the airport of Keflavik in Iceland as well as airports in England, Scotland and Scandinavia were closed for some time, which caused the cancellation or change of about 500 flights in Europe. Even in Germany the airports of Bremen, Hamburg and Berlin were closed for several hours on 25 May 2011. During this eruption period in May 2011, a team of the Duesseldorf University of Applied Sciences, the University of Iceland, the University of Reykjavik and the IMO has performed airborne in-situ measurements over Iceland and Germany as well as ground based measurements in the south of Iceland. The ground based measurements were performed continuously during the whole eruption period at two significant positions (Skogar and Hvollsv{\"o}llur) with optical particle counters (OPCs). The measurement method was based on measuring the airborne concentrations of the classic aerosol components (PM10, PM2.5 and PM1) and TSP (total suspended particles) every 6 seconds. Additional measurement flights on Iceland were started already one day after the beginning of the eruption (twelve in-situ measurement flights) and marked the spatial and temporal spread of volcanic ash in the atmosphere. For the flights light slow flying piston engine powered airplanes where used. The flights over Iceland focused on the western part of Iceland in the region of Reykjavik and Keflavik and over the international airport in Keflavik and were mostly coordinated by ISAVIA. The measurement flights helped to keep Keflavik International Airport open for many additional hours despite of adverse predictions by the London VAAC model, because it was possible to observe the particle concentration on-line during the flights. In Germany a measurement flight was performed on 25 May 2012 over the northern part of Germany where the volcanic ash cloud was forecasted from the dispersion model of the London VAAC. This flight was performed on the behalf of the German Weather Service (DWD). The measurement flights revealed most time relative low airborne ash concentrations over western Iceland, although the groundbased measured ash concentrations in the south of Iceland nearer to the Grimsv{\"o}tn were very high. In Germany the measured concentrations during the flight were low enough to be consistent with the re-opening of the airports Bremen, Hamburg and Berlin, which were closed by the authorities for several hours on 25 May 2011 because of high concentration predictions by the VAAC-model. The measurement flights clearly proved that OPCs, based on slow flying piston-motor driven aircrafts, are very suitable for the determination of airborne ash particles during volcanic eruptions. This is an important issue for air traffic safety.}, language = {en} } @inproceedings{VogelWeberFischeretal.2012, author = {Vogel, Andreas and Weber, Konradin and Fischer, Christian and Prata, A.

The rate at which sulphur dioxide oxidises to sulphate aerosol is poorly constrained and measurements of downwind abundance are required to quantify the rate at which this process occurs. During July and November 2011, a series of measurements were performed in emissions from Etna Volcano, Sicily, using the University of Applied Sciences (Dusseldorf) research aircraft. Both in situ and remote sensing instrumentation was simultaneously deployed to quantify the down-wind characteristics of gases and particles in the plume emitted by the volcano. In situ particle characteristics were measured using a Grimm 1.109 optical particle counter (microparticles 0.25-32 microns) and Grimm 1320 diffusion electrometer (nanoparticles 25-300 nanometers). Column abundance of sulphur dioxide was measured using a vertically-pointing differential optical absorption spectrometer (DOAS). These measurements were compared to horizontal pathlength-integrated measurements of sulphur dioxide from the Airborne Volcanic Imaging Object Detector (AVOID). Down-wind plume dispersion was discriminated through a series of aircraft transects below and through the volcanic plume. The emissions contained large amounts of nanoparticles relative to microparticles, which reflects gas-phase nucleation of sulphate aerosol. The AVOID system discriminated horizontal layering of volcanic aerosol at altitudes of up to 12,000 ft from a detection range of >50 km. Plume boundaries were discriminated using a combination of the in situ and DOAS measurements in order to compare to the pathlength-integrated measurements from AVOID.}, subject = {Forschungsflugzeug}, language = {en} } @inproceedings{BeckersFassbenderSchmidt2012, author = {Beckers, Kristian and Faßbender, Stephan and Schmidt, Holger}, title = {An Integrated Method for Pattern-Based Elicitation of Legal Requirements Applied to a Cloud Computing Example}, series = {2012 Seventh International Conference on Availability, Reliability and Security}, booktitle = {2012 Seventh International Conference on Availability, Reliability and Security}, publisher = {IEEE}, address = {Prague}, isbn = {978-0-7695-4775-6}, doi = {10.1109/ARES.2012.25}, pages = {463 -- 472}, year = {2012}, abstract = {Considering legal aspects during software development is a challenging problem, due to the cross-disciplinary expertise required. The problem is even more complex for cloud computing systems, because of the international distribution, huge amounts of processed data, and a large number of stakeholders that own or process the data. Approaches exist to deal with parts of the problem, but they are isolated from each other. We present an integrated method for elicitation of legal requirements. A cloud computing online banking scenario illustrates the application of our methods. The running example deals with the problem of storing personal information in the cloud and based upon the BDSG (German Federal Data Protection Act). We describe the structure of the online banking cloud system using an existing pattern-based approach. The elicited information is further refined and processed into functional requirements for software development. Moreover, our method covers the analysis of security-relevant concepts such as assets and attackers particularly with regard to laws. The requirements artifacts then serve as inputs for existing patterns for the identification of laws relevant for the online banking cloud system. Finally, our method helps to systematically derive functional as well as security requirements that realize the previously identified laws.}, language = {en} } @inproceedings{RakowKorezkiBender2012, author = {Rakow, Thomas C. and Korezki, Vitali and Bender, Axel}, title = {Comparing the Contrast for Electronic and Traditional Whiteboards in a Real-life Environment}, series = {Proceedings Electronic Displays Conference 2012, Nuremberg, Germany}, booktitle = {Proceedings Electronic Displays Conference 2012, Nuremberg, Germany}, publisher = {Design \& Elektronik [i.e. WEKA-Fachmedien]}, address = {Haar}, year = {2012}, language = {en} } @inproceedings{WeberReichardtFischeretal.2012, author = {Weber, Konradin and Reichardt, R. and Fischer, Christian and Moser, H.

There a several wide spread and/or sophisticated solutions to fulfill this need but they seem to have some flaws. One popular system at the time of writing is an overlay frame that can be placed on a normal display with the corresponding size. The frame creates a grid with infrared light emitting diodes. The disruption of this grid can be detected and messages with the positions are sent via usb to a connected computer. This system is quite robust in matters of ambient light insensitivity and also fast to calibrate. Unfortunately it is not created with the recognition of tangibles in mind and printed patterns can not be resolved. This article summarizes an attempt to create fiducials that are recognized by an infrared multi-touch frame as fingers. Those false fingers are checked by a software for known patterns. Once a known pattern (= fiducial) has been recognized its position and orientation are send with the finger positions towards the interactive software.
