In this report, we present the implementation and final results of parallel programming on graphics processing units (GPUs) using NVIDIA’s parallel programming model which is known as the Compute Unified Device Architecture (CUDA) to perform the 3D finite-difference seismic forward modeling. The Tesla 10-series GPU (Tesla C1060) is used and results show that the massively parallel computational...

A superconducting electron-positron linear collider (TESLA) of about 33km length with an x-ray free electron user facility is currently being planned and developed by an international collaboration at the Deutsches Elektronen-Synchrotron DESY. For the realization of the TESLA project a lot of basic survey and geodata are necessary and requested by design and construction. To operate the acceler...

This paper briefly summarizes the development of magnetic resonance imaging and spectroscopy in medicine. Aspects of magnetic resonancephysics and -technology relevant at ultra-high magnetic fields as well as current limitations are highlighted. Based on the first promising studies, potential clinical applications at 7 Tesla are suggested. Other aims are to stimulate awareness of the potential ...

We demonstrate that a measurement of the impact parameter in one-prong τ decay can be useful for the determination of the Higgs boson parity in the H/A → τ+τ−; τ± → ρ±ν̄τ (ντ ) decay chain. We have estimated that for a detection set-up such as TESLA, use of the information from the τ impact parameter can improve the significance of the measurement of the parity of the Standard Model 120 GeV Higg...

We consid Linear Collider Collaboration Tech Notes Abstract This note documents a set of expressions used to explore the issue of whether or not it is reasonable to consider a conventional positron source for a Tesla formatted beam. The critical issue is that of energy deposition in the conversion target and the comparison of the induced stress with the ultimate tensile strength of the target m...

This paper examined whether FreeSurfer-generated data differed between a fully-automated, unedited pipeline and an edited pipeline that included the application of control points to correct errors in white matter segmentation. In a sample of 30 individuals, we compared the summary statistics of surface area, white matter volumes, and cortical thickness derived from edited and unedited datasets ...
