The oscillation frequency is 11.6 GHz, which is significantly higher than the modulation bandwidth of less than 4 GHz in the device. The oscillation frequency is determined by an additional resonance frequency in birefringence containing microcavities, which is potentially much higher than the conventional relaxation oscillation frequency. The damping of the oscillations can be controlled by the current, allowing for oscillation lifetimes much longer than the spin lifetime in the device as well as for short bursts potentially interesting for information transmission.}}, author = {{Gerhardt, N.

Since some material parameters (mainly \textgreek{e}S 11, e15and cE 44) do not or only marginally influence the electrical impedance over frequency, it is not sufficient to look only at the electri- cal impedance of discoidal piezoceramics [1]. Moreover, the parameter sensitivities vary with respect to the diameter-thickness ratio of the disc and the design of an ultrasonic transducer's piezoceramic has to match other requirements than those of a good material characterization [2, 3]. That is why it is still desirable to find model based approaches for parameter identification that either keep the technical effort low (e.g., only an impedance measurement) or increase speed of the inversion procedure. In this contribution we answer the question if an additional analytical approximation of cE 44, strictly following the ideas of Theocaris [4], in conjunction with a single measured elec- trical impedance will be sufficient for an accurate simulation of both, electrical impedance and surface normal velocity of a piezoceramic disc. Thereby, the remaining parameters are identified by means of the Inverse Method. Furthermore, we use the parameter ap- proximation as an initial guess and limiting boundary to speed up the inverse algorithm if both, electrical impedance and surface normal velocity are taken into account within the optimization procedure.}}, author = {{Rautenberg, Jens and Rupitsch, Stefan J. and Henning, Bernd and Lerch, Reinhard}}, booktitle = {{7th International Workshop on Direct and Inverse Problems in Piezoelectricity}}, title = {{{Utilizing an Analytical Approximation for c44E to Enhance the Inverse Method for Material Parameter Identification of Piezoceramics}}}, year = {{2011}}, } @article{64492, author = {{Li, Mingyuan and Jähme, Hendrik and Soldat, Henning and Gerhardt, Nils Christopher and Hofmann, Martin and Ackemann, Thorsten}}, journal = {{2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO Europe/EQEC 2011)}}, pages = {{109}}, title = {{{Birefringence and spin controlled ultrafast polarization oscillations in vertical-cavity surface-emitting lasers}}}, doi = {{10.1109/cleoe.2011.5942549}}, year = {{2011}}, } @inbook{64675, author = {{Glöckner, Helge}}, booktitle = {{Developments and trends in infinite-dimensional Lie theory}}, isbn = {{978-0-8176-4740-7; 978-0-8176-4741-4}}, keywords = {{22E65, 22E15, 46A13, 46T05, 54D50}}, pages = {{243–280}}, publisher = {{Basel: Birkhäuser}}, title = {{{Direct limits of infinite-dimensional Lie groups}}}, doi = {{10.1007/978-0-8176-4741-4_8}}, year = {{2011}}, } @phdthesis{64745, author = {{Dahmen, Rafael}}, title = {{{Direct limit constructions in infinite dimensional Lie theory}}}, year = {{2011}}, } @book{57343, editor = {{Marchetti, Andreas and Clouet, Louis-Marie}}, pages = {{304}}, publisher = {{Nomos}}, title = {{{Europa und die Welt 2020: Entwicklungen und Tendenzen}}}, volume = {{74}}, year = {{2011}}, } @misc{57354, author = {{Bürgel, Christoph and Lutjeharms, Madeline and Claudia, Schmidt}}, booktitle = {{französisch heute}}, pages = {{101--102}}, title = {{{Lesekompetenz in Erst-, Zweit- und Fremdsprache, Giessener Beiträge zur Fremdsprachendidaktik}}}, year = {{2011}}, } @article{57378, author = {{Bürgel, Christoph}}, journal = {{Hispanorama }}, pages = {{67--76}}, title = {{{Ojalá viva el subjuntivo! – Grammatik und didaktische Transformation des subjuntivo für den Spanischunterricht}}}, volume = {{131}}, year = {{2011}}, } @article{57377, author = {{Bürgel, Christoph}}, journal = {{Varietäten im Französischunterricht, I.

In this work, we try to solve the problem of automatic simulation data generation targeting HDL mutation faults. We follow a search based approach and eliminate the need for symbolic execution and mathematical constraint solving from existing work. An objective cost function is defined on the test input space and serves the guidance of search for fault-detecting test data. This is done by first mapping the simulation traces under a test onto a control and data flow graph structure which is extracted from the design. Then the progress of fault detection can be measured quantitatively on this graph to be the cost value. By minimizing this cost we approach the target test data. The effectiveness of the cost function is investigated under an example neighborhood search scheme. Case study with a floating point arithmetic IP design has shown that the cost function is able to guide effectively the search procedure towards a fault-detecting test. The cost calculation time as the search overhead was also observed to be minor compared to the actual design simulation time.}}, author = {{Xie, Tao and Müller, Wolfgang and Letombe, Florian}}, booktitle = {{Proceedings of Euromicro DSD 2011}}, isbn = {{978-1-4577-1048-3}}, keywords = {{Hardware design languages, Cost function, Computational modeling, Fault detection, Data models, Analytical models, Testing}}, publisher = {{IEEE}}, title = {{{HDL-Mutation Based Simulation Data Generation by Propagation Guided Search}}}, doi = {{10.1109/DSD.2011.83}}, year = {{2011}}, } @inbook{58877, author = {{Milkov, Nikolay}}, booktitle = {{Sex, Love, and Friendship}}, editor = {{ Leigh McEvoy, Adrianne}}, isbn = {{978-90-420-3368-9}}, pages = {{155–165}}, publisher = {{Brill}}, title = {{{Sexual Experience}}}, doi = {{10.1163/9789401200684_019}}, volume = {{232}}, year = {{2011}}, }
