One IGEX Ge double-beta decay detector is currently operating in the Canfranc Underground Laboratory in a search for dark matter WIMPs, through the Ge nuclear recoil produced by the WIMP elastic scattering. A new exclusion plot, σ(m), has been derived for WIMP-nucleon spin-independent interactions. To obtain this result, 40 days of data from the IGEX detector (energy threshold Ethr ∼ 4 keV), re...

Scaled Largest Eigenvalue (SLE) detector stands out as the optimal single-primary-user detector in uncertain noisy environments. In this paper, we consider a multi-antenna cognitive radio system in which we aim at detecting the presence/absence of a Primary User (PU) using the SLE detector. By the exploitation of the distributions of the largest eigenvalue and the trace of the receiver sample c...

IceCube-DeepCore is a compact Cherenkov detector located in the clear ice of the bottom center of the IceCube Neutrino Telescope. Its purpose is to enhance the sensitivity of IceCube for low neutrino energies (< 1 TeV) and to lower the detection threshold of IceCube by about an order of magnitude to below 10 GeV. The detector is formed by 6 additional strings of 360 high quantum efficiency phot...

A massive parallel trigger system for efficient data reduction and event recognition is under design for the 14400 channels of the AUGER fluorescence detector. The trigger is combined with a cost-effective control and readout by PCI devices. The first level trigger includes a count-rate dependent trigger-threshold and suppresses Cerenkov pulses, and the second level trigger will identify straig...

We present a CMOS image sensor dedicated to lightning detection and imaging. The detector has been designed to evaluate the potentiality of an on-chip lightning detection solution based on a smart sensor. This evaluation is performed in the frame of the predevelopment phase of the lightning detector that will be implemented in the Meteosat Third Generation Imager satellite for the European Spac...

Terahertz detection capability of an n-type heterojunction interfacial work function internal photoemission (HEIWIP) detector is demonstrated. Threshold frequency, f0, of 3.2 THz (93 lm) was obtained by using n-type GaAs emitter doped to 1 · 10 cm 3 and Al0.04Ga0.96As single barrier structure. The detector shows a broad spectral response from 30 to 3.2 THz (10–93 lm) with peak responsivity of 6...

We investigate the use of voicing in state-of-the-art Large Vocabulary Continuous Audio-visual automatic Speech Recognition (AV-LVCSR). In this work we apply an original adaptive weighting function using voicing level to estimate the appropriate combination weights for each of the modalities. We show that we can improve the state-of-the-art AV-LVCSR performance under speech noise by using a det...

Slow coincidence circuits for the anti-coincidence measurements have been considered for use in Compton suppression technique. The simplified version of the slow circuit has been found to be fast enough, satisfactory and allows an easy system setup, particularly with the advantage of the automatic threshold setting of the low level discrimination. A well-type NaI detector as the main detector s...

We report on the preparation of and calibration measurements with a $^{83\mathrm{m}}$Kr source for CENNS-10 liquid argon detector. atoms generated in decay $^{83}$Rb were introduced into detector via injection Ar circulation loop. Scintillation light arising from 9.4 keV 32.1 conversion electrons volume then observed. This allows characterization low-energy response is applicable to other low-e...

We present a scheme for linear optical quantum computation that is highly robust to imperfect single photon sources and inefficient detectors. In particular we show that if the product of the detector efficiency with the source efficiency is greater than 2/3, then efficient linear optical quantum computation is possible. This high threshold is achieved within the cluster state paradigm for quan...
