One of the fundamental problems in many-pixel detectors implemented in cryogenics environments is the number of bias and read-out wires. If one targets a megapixel range detector, number of wires should be significantly reduced. One possibility is that the detectors are serially connected and biased by using only one line and read-out is accomplished by on-chip circuitry. In addition to the num...

The KM3NeT collaboration is constructing two large neutrino detectors in the Mediterranean Sea: ARCA, located near Sicily and aiming at astronomy, ORCA, Toulon designed for oscillation studies. detectors, together, will have hundreds of Detection Units (DUs) with 18 Digital Optical Modules (DOMs) maintained vertical by buoyancy, forming a 3D optical array detecting Cherenkov light produced afte...

We introduce an object recognition system in which objects are represented as a sparse and spatially organized set of local (bent) line segments. The line segments correspond to binarized Gabor wavelets or banana wavelets, which are bent and stretched Gabor wavelets. These features can be metrically organized, the metric enables an efficient learning of object representations. Learning can be p...

Traditionally, failure detectors have considered a binary model whereby a given process can be either trusted or suspected. This paper defines a family of failure detectors, called accrual failure detectors, that revisits this interaction model. Accrual failure detectors associate to each process a real value representing a suspicion level. An important advantage of accrual failure detectors ov...

Edge detection is a fundamental stage in order to facilitate the analysis or the interpretation of an image. However classical edge detectors usually yield gaps in the contour image. To restore incomplete contours, criteria based on perceptual grouping have been proposed. Almost all existing closing algorithms based only on these criteria fail at discontinuity points junction. In this perspecti...

We are developing focal plane arrays of bolometric detectors for sub-millimeter and millimeter-wave astrophysics. We propose a flexible array architecture using arrays of slot antennae coupled via low-loss superconducting Nb transmission line to microstrip filters and antenna-coupled bolometers. By combining imaging and filtering functions with transmission line, we are able to realize unique s...

The knowledge of the noise Power Spectral Density of interferometric detector of gravitational waves is fundamental for detection algorithms and for the analysis of the data. In this paper we address both to the problem of identifying the noise Power Spectral Density of interferometric detectors by parametric techniques and to the problem of the whitening procedure of the sequence of data. We w...

We continue our study of document marking t o deter illicit dissemination. A n experiment we performed reveals that the distortion on the photocopy of a document is very different in the vertical and horizontal directions. This leads to the strategy that marks a text line both vertically using line shifting and horizontally using word shifting. A line that is marked is always accompanied by two...

Conventional readout systems exist in many variants since the usual approach is to build readout electronics for one given type of detector. The Scalable Readout System (SRS) developed within the RD51 collaboration relaxes this situation considerably by providing a choice of frontends which are connected over a customizable interface to a common SRS DAQ architecture. This allows sharing develop...
