Several multichannel approaches have been proposed to try to tackle these problems, including RF shimming, where each element in an array is driven by its own amplifier and modulated with a certain (constant) amplitude and phase relative to the other elements, and Transmit SENSE, where spatially tailored RF pulses are used. In this article, a relatively inexpensive and easy to use imaging scheme for 7 Tesla imaging is proposed to mitigate signal voids due to B1 field inhomogeneity. Two time-interleaved images are acquired using a different excitation mode for each. By forming virtual receive elements, both images are reconstructed together using GRAPPA to achieve a more homogeneous image, with only small SNR and SAR penalty in head and body imaging at 7 Tesla.}, language = {en} } @inproceedings{KurulganDemirciLinderDemircietal.2010, author = {Kurulgan Demirci, Eylem and Linder, Peter and Demirci, Taylan and Gierkowski, Jessica R. and Digel, Ilya and Gossmann, Matthias and Temiz Artmann, Ayseg{\"u}l}, title = {rhAPC reduces the endothelial cell permeability via a decrease of cellular mechanical contractile tensions : [abstract]}, year = {2010}, abstract = {In this study, the CellDrum technology quanitfying cellular mechanical tension on a pico-scale was used to investigate the effect of LPS (lipopolysaccharide) on HAoEC (Human Aortic Endothelial Cell) tension.}, subject = {Endothelzelle}, language = {en} } @book{Thomas2010, author = {Thomas, Axel}, title = {Rhetorische Knallfr{\"o}sche : Zitatensammlung f{\"u}r Politik und Wirtschaft}, publisher = {Neck + Heyn}, address = {Aachen}, isbn = {978-3-00-033037-7}, pages = {145 S. : Ill.}, year = {2010}, language = {de} } @article{Ferrein2010, author = {Ferrein, Alexander}, title = {Robot controllers for highly dynamic environments with real-time constraints}, series = {K{\"u}nstliche Intelligenz : KI. 24 (2010), H. 2}, journal = {K{\"u}nstliche Intelligenz : KI. 24 (2010), H. 2}, isbn = {1610-1987}, pages = {175 -- 178}, year = {2010}, language = {en} } @inproceedings{Anthrakidis2010, author = {Anthrakidis, Anette}, title = {Schnelltest zur Absch{\"a}tzung der Wirkungsgradkennlinie von Parabolrinnenkollektoren}, series = {Thermische Solarenergie : 20.

Few studies have been published on possible cognitive effects of MRI examinations. The aim of this study was to examine whether changes are measurable after MRI examinations at 1.5 and 7 T by means of transcranial magnetic stimulation (TMS). Materials and Methods TMS was performed in 12 healthy, right-handed male volunteers. First the individual motor threshold was specified, and then the cortical silent period (SP) was measured. Subsequently, the volunteers were exposed to the 1.5-T MRI scanner for 63 minutes using standard sequences. The MRI examination was immediately followed by another TMS session. Fifteen minutes later, TMS was repeated. Four weeks later, the complete setting was repeated using a 7-T scanner. Control conditions included lying in the 1.5-T scanner for 63 minutes without scanning and lying in a separate room for 63 minutes. TMS was performed in the same way in each case. For statistical analysis, Wilcoxon's rank test was performed. Results Immediately after MRI exposure, the SP was highly significantly prolonged in all 12 subjects at 1.5 and 7 T. The motor threshold was significantly increased. Fifteen minutes after the examination, the measured value tended toward normal again. Control conditions revealed no significant differences. Conclusion MRI examinations lead to a transient and highly significant alteration in cortical excitability. This effect does not seem to depend on the strength of the static magnetic field.}, language = {en} } @inproceedings{GligorevicPulini2010, author = {Gligorevic, Snjezana and Pulini, Paola}, title = {Simplified airport surface channel model based on the WSSUS assumption}, series = {2010 Integrated Communications, Navigation and Surveillance Conference (ICNS 2010) : Herndon, Virginia, USA, 11 - 13 May 2010}, booktitle = {2010 Integrated Communications, Navigation and Surveillance Conference (ICNS 2010) : Herndon, Virginia, USA, 11 - 13 May 2010}, organization = {Institute of Electrical and Electronics Engineers}, isbn = {978-1-4244-7457-8}, issn = {2155-4943}, pages = {F2-1 -- F2-11}, year = {2010}, language = {en} } @inproceedings{SchuermannLeidingerWollert2010, author = {Sch{\"u}rmann, Volker and Leidinger, R. and Wollert, J{\"o}rg}, title = {Simplified rapid-prototyping with automation technology}, series = {Automobiles and sustainable mobility : FISITA 2010 World Automotive Congress, 30 May - 4 June, Budapest, Hungary ; proceedings}, booktitle = {Automobiles and sustainable mobility : FISITA 2010 World Automotive Congress, 30 May - 4 June, Budapest, Hungary ; proceedings}, organization = {FISITA 2010 World Automotive Congress }, isbn = {978-963-9058-29-3}, pages = {F2010C093}, year = {2010}, language = {en} } @inproceedings{GallAbelAhlbrinketal.2010, author = {Gall, J. and Abel, Dirk and Ahlbrink, N. and Pitz-Paal, R. and Andersson, J. and Diehl, M. and Teixeira Boura, Cristiano Jos{\´e} and Schmitz, M. and Hoffschmidt, Bernhard}, title = {Simulation and control of solar thermal power plants}, series = {International Conference on Renewable Energies and Power Quality : ICREPQ '10 : Granada 23rd - 25th March 2010}, booktitle = {International Conference on Renewable Energies and Power Quality : ICREPQ '10 : Granada 23rd - 25th March 2010}, pages = {1 -- 5}, year = {2010}, language = {en} } @article{KernFrentzelBehrens2010, author = {Kern, Alexander and Frentzel, Ralf and Behrens, J{\"o}rg}, title = {Simulation of the transient voltages in the auxiliary power network of a large power plant in case of a direct lightning strike to the high-voltage overhead transmission line}, pages = {749-1 -- 749-7}, year = {2010}, language = {en} } @inproceedings{AlexopoulosHoffschmidtRauetal.2010, author = {Alexopoulos, Spiros and Hoffschmidt, Bernhard and Rau, Christoph and Schmitz, M. and Schwarzb{\"o}zl, P. and Pomp, Stefan}, title = {Simulation results for a hybridized operation of a gas turbine or a burner for a small solar tower power plant}, series = {SolarPACES 2010 : the CSP Conference: electricity, fuels and clean water from concentrated solar energy ; 21 to 24 September 2010, Perpignan, France}, booktitle = {SolarPACES 2010 : the CSP Conference: electricity, fuels and clean water from concentrated solar energy ; 21 to 24 September 2010, Perpignan, France}, publisher = {Soc.

The most common biofuels today are biodiesel and bioethanol. Since diesel engines are rather rare in aviation this survey is focusing on ethanol admixed to gasoline products. The Directive 2003/30/EC of the European Parliament and the Council of May 8th 2003 on the promotion of the use of biofuels or other renewable fuels for transport encourage a growing admixture of biogenic fuel components to fossil automotive gasoline. Some aircraft models equipped with spark ignited piston engines are approved for operation with automotive gasoline, frequently called "MOGAS" (motor gasoline). The majority of those approvals is limited to MOGAS compositions that do not contain methanol or ethanol beyond negligible amounts. In the past years (bio-)MTBE or (bio-)ETBE have been widely used as blending component of automotive gasoline whilst the usage of low-molecular alcohols like methanol or ethanol has been avoided due to the handling problems especially with regard to the strong affinity for water. With rising mandatory bio-admixtures the conversion of the basic biogenic ethanol to ETBE, causing a reduction of energetic payoff, becomes more and more unattractive. Therefore the direct ethanol admixture is accordingly favoured. Due to the national enforcements of the directive 2003/30/EC more oxygenates produced from organic materials like bioethanol have started to appear in automotive gasolines already. The current fuel specification EN 228 already allows up to 3 \% volume per volume (v/v) (bio-)methanol or up to 5 \% v/v (bio-)ethanol as fuel components. This is also roughly the amount of biogenic components to comply with the legal requirements to avoid monetary penalties for producers and distributors of fuels. Since automotive fuel is cheaper than the common aviation gasoline (AVGAS), creates less problems with lead deposits in the engine, and in general produces less pollutants it is strongly favoured by pilots. But being designed for a different set of usage scenarios the use of automotive fuel with low molecular alcohols for aircraft operation may have adverse effects in aviation operation. Increasing amounts of ethanol admixtures impose various changes in the gasoline's chemical and physical properties, some of them rather unexpected and not within the range of flight experiences even of long-term pilots.}, language = {en} } @article{Fabo2010, author = {Fabo, Sabine}, title = {Sisyphus wird Steiff}, series = {Pr{\"a}dikat spießig (Boxhorn ; 21)}, volume = {2010}, journal = {Pr{\"a}dikat spießig (Boxhorn ; 21)}, editor = {Mohr, Klaus}, publisher = {FH Aachen, Fachbereich Gestaltung}, address = {Aachen}, issn = {1864-2535}, pages = {58 -- 61}, year = {2010}, abstract = {Eine Reise durch die fremde Welt eines Kaufhaus-Schaufensters.

This chapter covers their orbital and attitude dynamics and control. First, the advantages and limitations of solar sails are discussed and their history and development status is outlined. Because the dynamics of solar sails is governed by the (thermo-)optical properties of the sail film, the basic solar radiation pressure force models have to be described and compared before parameters to measure solar sail performance can be defined. The next part covers the orbital dynamics of solar sails for heliocentric motion, planetocentric motion, and motion at Lagrangian equilibrium points. Afterwards, some advanced solar radiation pressure force models are described, which allow to quantify the thrust force on solar sails of arbitrary shape, the effects of temperature, of light incidence angle, of surface roughness, and the effects of optical degradation of the sail film in the space environment. The orbital motion of a solar sail is strongly coupled to its rotational motion, so that the attitude control of these soft and flexible structures is very challenging, especially for planetocentric orbits that require fast attitude maneuvers. Finally, some potential attitude control methods are sketched and selection criteria are given.}, language = {en} } @article{AlexopoulosHoffschmidt2010, author = {Alexopoulos, Spiros and Hoffschmidt, Bernhard}, title = {Solar tower power plant in Germany and future perspectives of the development of the technology in Greece and Cyprus}, series = {Renewable Energy . 35 (2010), H. 7}, journal = {Renewable Energy . 35 (2010), H. 7}, isbn = {0960-1481}, pages = {1352 -- 1356}, year = {2010}, language = {en} } @inproceedings{Anthrakidis2010, author = {Anthrakidis, Anette}, title = {Solare-Prozessw{\"a}rme-Standards (Sol-Pro-St)}, series = {Thermische Solarenergie : 20.

Methods We applied different rules to construct binary and weighted networks from EEG and MEG data recorded under a resting-state eyes-open and eyes-closed condition from 21 epilepsy patients and 23 healthy controls. The average shortest path length and the clustering coefficient served as global statistical network characteristics. Results Independent on the behavioral condition, epileptic brains exhibited a more regular functional network structure. Similarly, the eyes-closed condition was characterized by a more regular functional network structure in both groups. The amount of network reorganization due to behavioral state changes was similar in both groups. Consistent findings could be achieved for networks derived from EEG but hardly from MEG recordings, and network construction rules had a rather strong impact on our findings. Conclusions Despite the locality of the investigated processes epileptic brain networks differ in their global characteristics from non-epileptic brain networks. Further methodological developments are necessary to improve the characterization of disturbed and normal functional networks.

Using structural analysis, the vessel diameters were measured. Using functional analysis, the endothelium-dependent vessel dilation in response to flicker light stimulation was assessed. In the patients after coarctation repair, the retinal arteriolar diameter was significantly reduced compared to that of the controls (median 182 μm, first to third quartile 171 to 197; vs 197 μm, first to third quartile 193 to 206; p <0.001). These findings were independent of the peripheral blood pressure and age at intervention. No differences were found for venules. The functional analysis findings were not different between the patients and controls (maximum dilation 3.5\%, first to third quartile 2.1\% to 4.5\% vs 3.6\%, first to third quartile 2.2\% to 4.3\%; p = 0.81), indicating preserved autoregulative mechanisms. In conclusion, the retinal artery diameter is reduced in patients after coarctation repair, independent of their current blood pressure level and age at intervention. As a structural marker of chronic vessel damage associated with past, current, or future hypertension, retinal arteriolar narrowing has been linked to stroke incidence. These results indicate an involvement of cerebral microcirculation in aortic coarctation, despite timely repair, and might contribute to explain the increased rate of cerebrovascular events in such patients.}, language = {en} } @book{HoffschmidtLanFrickeetal.2010, author = {Hoffschmidt, Bernhard and Lan, Marco and Fricke, Barbara and Anthrakidis, Anette and Peter, Stefan}, title = {Struktur und Dynamik einer Stromversorgung mit einem hohen Anteil erneuerbarer Energieerzeuger.

Insights into plant adjustments to changing environmental conditions have mainly been obtained through structural and functional comparative studies between taxa or within taxa on contrasting sites or along environmental gradients. Yet, a gap exists regarding the study of hydraulic adjustments in response to environmental changes over the lifetimes of plants. In trees, dated tree-ring series are often exploited to reconstruct dynamics in ecological conditions, and recent work in which wood-anatomical variables have been used in dendrochronology has produced promising results. Environmental signals identified in water-conducting cells carry novel information reflecting changes in regional conditions and are mostly related to short, sub-annual intervals. Although the idea of investigating environmental signals through wood anatomical time series goes back to the 1960s, it is only recently that low-cost computerized image-analysis systems have enabled increased scientific output in this field. We believe that the study of tree-ring anatomy is emerging as a promising approach in tree biology and climate change research, particularly if complemented by physiological and ecological studies.

Contradictory to fossil fuel power plants, energy production of wind and photovoltaic (PV) energy is fluctuating. Although predictions have significantly improved, an outage of multi-MW offshore wind farms poses a challenging problem. One solution could be the integration of storage systems in the grid. After a short overview, this paper focuses on two exemplary battery storage systems, including the required power electronics. The grid integration, as well as the optimal usage of volatile energy reserves, is presented for a 5- kW PV system for home application, as well as for a 100- MW medium-voltage system, intended for wind farm usage. The efficiency and cost of topologies are investigated as a key parameter for large-scale integration of renewable power at medium- and low-voltage.}, 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} } @article{HerzogPietrzykShahetal.2010, author = {Herzog, Hans and Pietrzyk, Uwe and Shah, N.
