The Histogram Probabilistic Multi-Hypothesis Tracker (H-PMHT) algorithm is a parametric track-before-detect method. It locates targets in imagery by fitting a mixture of probability densities. In recent work, an unknown target shape was accommodated through the use of a Wishart prior on the measurement probability density, this version of the algorithm is referred to as H-PMHT-RM. This paper ap...

Application of a simple approach for the soft-decision decoding of Maximum-Transition-Run (MTR) codes has been presented in this paper. A lowdemanded hardware realization have been proposed for soft-decision decoding in MTR basic AND, OR and XOR logic circuits. The suggested approach is explored over the two-track, two-head EPR4 partial response magnetic recording system. The overall two-track ...

Solid-state Auger-electron angular distributions are known to be largely independent of the type of excitation, following roughly a cosine law for low ejection energies. In this Letter it is shown that the ion-track dynamics and the corresponding high electron temperatures lead to significant variations of these Auger distributions. Ratios for different degrees of inner-shell ionization versus ...

Object tracking with multiple cameras is more efficient than tracking with one camera. In this paper, we propose a multiple-camera multiple-object tracking system that can track 3D object locations even when objects are occluded at cameras. Our system tracks objects and fuses data from multiple cameras by using the probability hypothesis density filter. This method avoids data association betwe...

Off-track interference (OTI) arises as a result of head misalignment and is likely to become the dominant source of errors in future magnetic storage systems with high track density. In this paper, using a two-track and single-head model for OTI, we compare two different equalization/detection techniques aiming at recovering data from only the main track. One is a conventional approach based on...

In this paper, an adaptive collaborative Gaussian Mixture Probability Hypothesis Density (ACo-GMPHD) filter is proposed for multi-target tracking with automatic track extraction. Based on the evolutionary difference between the persistent targets and the birth targets, the measurements are adaptively partitioned into two parts, persistent and birth measurement sets, for updating the persistent ...

Introduction Single event effects (SEE’s) induced by heavy-ions from cosmic-rays are a major problem for the reliability of microelectronic devices in space environment. The energy deposited by a heavy-ion through the sensitive structure of a device produces, in a very short time, a dense concentration of electron-hole pairs along the ion trajectory. Generated carriers are collected by drift (i...

indoor radon and thoron have been measured in the houses ofmoradabad district, uttar pradesh india, by means of solid state nuclear trackdetectors. radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. radon exists in soil gas building materials and indooratmosphere to name but a f...

Operating points to achieve Terabyte tape cartridge capacities and beyond drive both linear and track densities to values not perceived possible a few short years ago. The primary contributors to the issues related to these high capacities are the physical and magnetic properties of the tape media itself. The total magnetic moment of the recorded bit, driven by the magnetic coating thickness, d...

We report on the development and performance of a novel track-finding processor for the Level-1 trigger of the CMS endcap muon system. The processor links track segments identified in the cathode-strip chambers of the endcap muon system into complete threedimensional tracks. It then measures the momentum of the best track candidates from the sagitta measured between three muon chambers in the e...
