The results were analysed considering the macroscopic symmetry as well as symmetry resulting from local Na-Bi ordering in all three known phases. An overdamped infrared soft mode was revealed in the THz range which, together with central-mode type dispersion in the GHz range, contribute to the strong and broad dielectric permittivity maximum around 600 K. Anharmonic Bi and/or Na vibrations and local hopping, respectively, are suggested to be the main origins of these excitations. The broad phonon spectra and the frequency independent dielectric losses at low temperatures are compatible with the existence of nanoscopic polar regions and disorder to liquid He temperatures similar to relaxor ferroelectrics.Thu Aug 04 00:00:00 CEST 2011FPLconf/fpl/2004791-800Lecture Notes in Computer ScienceUsing of FPGA Coprocessor for Improving the Execution Speed of the Pattern Recognition Algorithm for ATLAS - High Energy Physics Experiment.32032004dblp Sat Jun 11 00:00:00 CEST 2011IJUC3-4209-222You Don't Need a Hypercomputer to Evaluate an Uncomputable Function.52009dblp Mon Sep 21 00:00:00 CEST 2009DATEconf/date/200939-44DPR in high energy physics.2009dblp Fri Aug 21 09:49:34 CEST 2009München63Hochschulschriften zur BetriebswirtschaftslehreDie Besteuerung öffentlicher Betriebe1989Betriebliches_Prüfungswesen Betriebswirtschaftliche_Steuerlehre Steuerrecht Öffentliches_Unternehmen Fri Aug 21 09:46:50 CEST 2009Lexington, Mass.

As a neutral beam propagates through a plasma, collisions of the beam particles with the background ions and electrons will excite beam atoms, leading to emission of radiation. The motional Stark effect, which arises from the electric field induced in the atom's rest frame due to the beam motion across the magnetic field ($E=V_{\rm beam} \times B$), causes a wavelength splitting of several angstroms and polarization of the emitted radiation. The $m=\pm 1$ transitions, or components, from the beam fluorescence are linearly polarized parallel to the direction of the local magnetic field when viewed transverse to the fields. Since the hydrogen beam provides good spatial localization and penetration, the pitch angle can be obtained anywhere in the plasma. A photoelastic modulator (PEM) is used to modulate the linearly polarized light. Depending on the orientation of the PEM, it can measure the sine or cosine of the angle of polarization. Two PEM's are used to measure both components simultaneously. Results of $q(r)$ for both Ohmic and NBI heated discharges have been obtained in the Princeton Beta Experiment (PBX-M) tokamak, with an uncertainty of $\sim 6$\% for $q(0)$.Thu Jul 02 15:31:47 CEST 2009Phys.

The resulting $q(r)$ profile is very broad and its central value, $q(0)$, is significantly below 1, which has important implications for theoretical models of sawteeth.Fri Jul 18 15:16:48 CEST 2008Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsJUN1iMapping Wiks - Towards a Graphical Environment for Semantic Knowledge Management12006Wiki iMapping imported Wed Jun 25 19:30:29 CEST 2008Phys.
