Despite recent advances for many open research questions, these kind of systems are not widely used in real rescue missions. One reason is that such systems are complex and not (yet) very reliable; another is that one has to be an robotic expert to run such a system. Moreover, available rescue robots are very expensive and the benefits of using them are still limited. In this paper, we present the Scarab robot, an alternative design for a USAR robot. The robot is light weight, humanpackable and its primary purpose is that of extending the rescuer's capability to sense the disaster site. The idea is that a responder throws the robot to a certain spot. The robot survives the impact with the ground and relays sensor data such as camera images or thermal images to the responder's hand-held control unit from which the robot can be remotely controlled.}, language = {en} } @inproceedings{BonneyHoefkenPaffenetal.2015, author = {Bonney, Gregor and H{\"o}fken, Hans-Wilhelm and Paffen, Benedikt and Schuba, Marko}, title = {ICS/SCADA Security - Analysis of a Beckhoff CX5020 PLC}, series = {1st International Conference on Information Systems Security and Privacy : ICISSP 2015}, booktitle = {1st International Conference on Information Systems Security and Privacy : ICISSP 2015}, organization = {International Conference on Information Systems Security and Privacy <1, 2015, Angers>}, pages = {1 -- 6}, year = {2015}, language = {en} } @inproceedings{BhattaraiFrotscherSoraetal.2014, author = {Bhattarai, Aroj and Frotscher, Ralf and Sora, M.-C. and Staat, Manfred}, title = {A 3D finite element model of the female pelvic floor for the reconstruction of urinary incontinence}, series = {11th World Congress on Computational Mechanics (WCCM XI) ; 5th European Conference on Computational Mechanics (ECCM V) ; 6th European Conference on Computational Fluid Dynamics (ECFD VI) ; July 20-25, 2014, Barcelona}, booktitle = {11th World Congress on Computational Mechanics (WCCM XI) ; 5th European Conference on Computational Mechanics (ECCM V) ; 6th European Conference on Computational Fluid Dynamics (ECFD VI) ; July 20-25, 2014, Barcelona}, editor = {Onate, E.}, organization = {World Congress on Computational Mechanics <11, 2014, Barcelona>}, pages = {1 -- 12}, year = {2014}, language = {en} } @inproceedings{BassamDigelArtmann2009, author = {Bassam, Rasha and Digel, Ilya and Artmann, Gerhard}, title = {Effect of nitric oxide on protein thermal stability : [abstract]}, year = {2009}, abstract = {As a deduction from these results, we can conclude that proteins mainly in vitro, denaturate totally at a temperature between 57°C -62°C, and they also affected by NO and different ions types.

The modeling system acts under amperometric conditions. The microreactors were modeled by particles and by strips. The model is based on the diffusion equations containing a nonlinear term related to the Michaelis-Menten kinetics of the enzymatic reaction. The model involves three regions: an array of enzyme microreactors where enzyme reaction as well as mass transport by diffusion takes place, a diffusion limiting region where only the diffusion takes place, and a convective region, where the analyte concentration is maintained constant. Using computer simulation, the influence of the geometry of the microreactors and of the diffusion region on the biosensor response was investigated.

Images of Enceladus' South Pole showed several fissures in the ice shell with plumes constantly exhausting frozen water particles, building up the E-Ring, one of the outer rings of Saturn. In this southern region of Enceladus, the ice shell is considered to be as thin as 2 km, about an order of magnitude thinner than on the rest of the moon. Under the ice shell, there is a global ocean consisting of liquid water. Scientists are discussing different approaches the possibilities of taking samples of water, i.e. by melting through the ice using a melting probe. FH Aachen UAS developed a prototype of maneuverable melting probe which can navigate through the ice that has already been tested successfully in a terrestrial environment. This means no atmosphere and or ambient pressure, low ice temperatures of around 100 to 150K (near the South Pole) and a very low gravity of 0,114 m/s^2 or 1100 μg. Two of these influencing measures are about to be investigated at FH Aachen UAS in 2017, low ice temperature and low ambient pressure below the triple point of water. Low gravity cannot be easily simulated inside a large experiment chamber, though. Numerical simulations of the melting process at RWTH Aachen however are showing a gravity dependence of melting behavior. Considering this aspect, VIPER provides a link between large-scale experimental simulations at FH Aachen UAS and numerical simulations at RWTH Aachen. To analyze the melting process, about 90 seconds of experiment time in reduced gravity and low ambient pressure is provided by the REXUS rocket. In this time frame, the melting speed and contact force between ice and probes are measured, as well as heating power and a two-dimensional array of ice temperatures. Additionally, visual and infrared cameras are used to observe the melting process.}, language = {en} } @inproceedings{ArtmannStadlerEmbsetal.2010, author = {Artmann, Gerhard and Stadler, Andreas M. and Embs, Jan P. and Zaccai, Giuseppe and B{\"u}ldt, Georg and Digel, Ilya and Temiz Artmann, Ayseg{\"u}l}, title = {The crucial role of water in a phase transition of hemoglobin at body temperature : [abstract]}, year = {2010}, abstract = {The observation of a temperature transition of hemoglobin occurring at a critical temperature close to body temperature}, subject = {H{\"a}moglobin}, language = {en} } @inproceedings{ArtmannDigelLinderetal.2011, author = {Artmann, Gerhard and Digel, Ilya and Linder, Peter and Temiz Artmann, Ayseg{\"u}l}, title = {Biophysical and Engineering Contributions to Plant Research}, year = {2011}, abstract = {Tests with palm tree leaves have just started yet and scan data are in the process to be analyzed.
