This paper extends the scale-invariant edge detector to the one-dimensional slope. It can accurately detect the slope and estimate its parameters. The method has been verified with several mathematical functions, sample sizes, and noise levels. A contrast-invariant operator is proposed to suppress noise. The inter-sample localization and interpolation greatly improve the accuracy. The proposed ...

|A procedure for obtaining a reduced complexity signal space detector is proposed and applied to the EEPR4 channel combined with d = 1 code. For the channel considered, the signal space detector requires at least 10 observation samples to attain the same minimum distance as the Viterbi algorithm (VA). The resulting signal space detector can be implemented with 7 linear discriminant functions, 1...

By controlling the thickness of the grating depth with chemical beam epitaxy (CBE) growth time, we report in this letter the design and performance of an integrated tunable detector. A carefully designed tunable active filter, which allows only one below threshold Fabry-Perot mode for operation, is integrated with a waveguide detector. The full tuning range of this kind of tunable device can no...

With an effective telescope area of order 10 m for TeV neutrinos, a threshold near ∼50 GeV and a pointing accuracy of 2.5 degrees per muon track, the AMANDA detector represents the first of a new generation of high energy neutrino telescopes, reaching a scale envisaged over 25 years ago. We describe early results on the calibration of natural deep ice as a particle detector as well as on AMANDA...

In this paper, we study the adaptive version of the asymptotical Bayesian Optimum Radar Detector (BORD) built with a covariance matrix estimate. We investigate its properties, when the noise is modelled as a non-Gaussian complex process, such as Spherically Invariant Random Process (SIRP). We derive, for appropriate covariance matrix estimates, the analytical expression of the relationship betw...

This document describes the Cherenkov detector that is to be constructed for the Hall A neutron d2 experiment (E06-014). The inclusive nature of that experiment makes the addition of the Cerenkov counter for pion and proton rejection critical for the low energy bins. Monte Carlo and analysis of G E suggest particle rates of (assuming a 500MeV ee threshold on the the BigBite shower detector): • ...

The plans for an upgrade of the Large Hadron Collider LHC to the Super-LHC (sLHC) are reviewed with special consideration of the environment for the inner tracking system. A straw-man detector upgrade for ATLAS is presented, which is motivated by the varying radiation levels as a function of radius, and choices for detector geometries and technologies are discussed in the context of required si...

Studies of η meson decays with the WASA detector are a major goal of the experimental program at COSY-Jülich. In 2008 a sample of 10 7 η mesons was collected in pd → 3 He η reaction close to threshold without trigger bias on the decay channels. The status of the analysis of various decay channels is presented. Studies of η meson decays with WASA A. Kupsc Figure 1: Schematic representation of th...

The nuclear track detector CR39 was calibrated with different ions of different energies. Due to the low detection threshold (Z/β ∼ 6e) and the good charge resolution (σZ ∼ 0.2e for 6e ≤ Z/β ≤ 83e with 2 measurements), the detector was used for different purposes: (i) fragmentation of high and medium energy ions; (ii) search for magnetic monopoles, nuclearites, strangelets and Q-balls in the co...

The detection performance of the generalized detector (GD) constructed based on the generalized approach to signal processing in noise is evaluated under homogeneous and non-homogeneous noise. The GD adaptive threshold is derived and defined applying an appropriate noise power estimation using the sliding window technique. The direct close expressions for the GD average probability of detection...
