The CBM Collaboration proposes to build a dedicated heavy-ion experiment to investigate the properties of highly compressed baryonic matter as it is produced in nucleus-nucleus collisions at the future accelerator facility in Darmstadt. Our goal is to explore the QCD phase diagram in the region of moderate temperatures but very high baryon densities. The(More)
A general purpose neurocomputer, SYNAPSE-1, which exhibits a multiprocessor and memory architecture is presented. It offers wide flexibility with respect to neural algorithms and a speed-up factor of several orders of magnitude--including learning. The computational power is provided by a 2-dimensional systolic array of neural signal processors. Since the(More)
This paper describes the general purpose neurocom-puter SYNAPSE–1 which has been developed in cooperation between Siemens Munich and the University of Mannheim. This system contains one of the most powerful processors available for neural algorithms, the neuro signal processor MA16. The prototype system executes a test algorithm 8,000 times as fast as a(More)
A central part of the work in Incident Commands (ICs) deals with handling messages that contain relevant information. Classification schemes for messages can be exploited by command staff and assisting tools to support this work, given that a common understanding of the scheme is shared among participants. We present user studies on two such(More)
The Active Buffer Board (ABB) was reIn order to test the redesigned ABB cards and to test memory and interconnection modules a number of IP-cores have been developed. The infrastructure module is based on the embedded PowerPC processor in the Virtex-4 FPGA. Specialised IP-cores to access the serial links and memory interface via the processor bus (PLB)(More)
The proton-nucleon cross section ratio R = Br(Υ → l + l −) · dσ(Υ)/dy| y=0 / σ(J/ψ) has been measured with the HERA-B spectrometer in fixed-target proton-nucleus collisions at 920 GeV proton beam energy corresponding to a proton-nucleon cms energy of √ s = 41.6 GeV. The combined results for the decay channels Υ → e + e − and Υ → µ + µ − yield a ratio R =(More)
A measurement of the polarization of Λ and Λ baryons produced in pC and pW collisions at √ s = 41.6 GeV has been performed with the HERA B spectrometer. The measurements cover the kinematic range of 0.6 GeV/c < p ⊥ < 1.2 GeV/c in transverse momentum and −0.15 < x F < 0.01 in Feynman-x. The polarization results from the two different targets agree within the(More)
The mid-rapidity (dσ pN /dy at y=0) and total (σ pN) production cross sections of J/ψ mesons are measured in proton-nucleus interactions. Data collected by the HERA-B experiment in interactions of 920 GeV/c protons with carbon, titanium and tungsten targets are used for this analysis. The J/ψ mesons are reconstructed by their decay into lepton pairs. The(More)
