Pattern Comparator Trigger (PACT) for the muon system of the CMS experiment
The general scheme for the fast, pipelined first level trigger on high pt muons in the CMS detector at LHC is presented. The prototype PACT system was tested in the high momentum muon beams in the RD5 experiment during 1993/94 runs. The obtained efficiency curves are shown
Inclusive Production Cross Sections from 920 GeV Fixed Target Proton-Nucleus Collisions
Inclusive differential cross sections and
for the production of \kzeros, \lambdazero, and
\antilambda particles are measured at HERA in proton-induced reactions on C,
Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to
GeV in the proton-nucleon system. The ratios of differential
cross sections \rklpa and \rllpa are measured to be and , respectively, for \xf . No significant dependence upon the
target material is observed. Within errors, the slopes of the transverse
momentum distributions also show no significant
dependence upon the target material. The dependence of the extrapolated total
cross sections on the atomic mass of the target material is
discussed, and the deduced cross sections per nucleon are
compared with results obtained at other energies.Comment: 17 pages, 7 figures, 5 table
The QCD transition temperature: results with physical masses in the continuum limit II.
We extend our previous study [Phys. Lett. B643 (2006) 46] of the cross-over
temperatures (T_c) of QCD. We improve our zero temperature analysis by using
physical quark masses and finer lattices. In addition to the kaon decay
constant used for scale setting we determine four quantities (masses of the
\Omega baryon, K^*(892) and \phi(1020) mesons and the pion decay constant)
which are found to agree with experiment. This implies that --independently of
which of these quantities is used to set the overall scale-- the same results
are obtained within a few percent. At finite temperature we use finer lattices
down to a <= 0.1 fm (N_t=12 and N_t=16 at one point). Our new results confirm
completely our previous findings. We compare the results with those of the
'hotQCD' collaboration.Comment: 19 pages, 8 figures, 3 table
Vorrichtung und Verfahren zum Erzeugen eines gefilterten Aktivitätsmusters, Quellentrenner, Verfahren zum Erzeugen eines bereinigten Audiosignals und Computerprogramm
DE 102006030276 A1 UPAB: 20080128 NOVELTY - The device (100) comprises an identifier (120) for identifying one trajectory in the one activity pattern and other trajectory in the other activity pattern, which are associated with the same sound event. The device has a filter (140) for filtering the one activity pattern or the other activity pattern based on a result of the determinator as to whether a trajectory is associated with a sound event of the wanted sound source, so that in the filtered activity pattern activity events that are associated with a sound event of the wanted sound source dominate. USE - Used for producing a filtered activity pattern, which is based on a activity pattern on a hearing model of an ear and another activity pattern on a hearing model of another ear. ADVANTAGE - The device enables a determination of a filter activity pattern in an efficient, reliable and hearing-adjusted manner, so that in the filtered activity pattern a wanted sound source is emphasized, while interference sound sources are suppressed or damped
Verfahren, Vorrichtung und Computerprogramm zum Erzeugen eines Ansteuersignals für ein Cochlea-Implantat basierend auf einem Audiosignal
The invention relates to a method for generating a control signal for a cochlea implant based on an audio signal, comprising a calculation (110) of first information on an activity pattern over time of a number of internal hair cells of an auditive model, arising from the audio signal. The method further comprises a filtering (120) of activity events described by the first information based on a recognition of a characteristic pattern in the activity pattern to give corrected information. The corrected information is then used as control signal for the cochlea implant, or the control signal is derived from the corrected information. Said method can be carried out by a computer programme or a corresponding device. By means of the above, for example, the auditive impression for patients with a cochlea implant can be significantly improved. A filtering of activity events, based on the recognition of a characteristic pattern in the activity pattern is particularly suitable to human hearing and permits the control of a cochlea implant such that the best possible speech recognition with the least possible energy use of a cochlea implant is achieved
