Object detection refers to identifying a location where an object can be present. It also includes registering components of a particular object class at various levels of detail. For example, finding the faces in an image, finding the eyes and mouths of faces. One could require a precise outline of the object in the image or detection of well-defined landmarks on the object. Object Detection a...

G. Boca1 11Fair Joint Core Team and GSI, Darmstadt, Germany and Dipartimento di Fisica Nucleare e Teorica dell’Universitá, via Bassi 6, 27100 Pavia, Italy In the experiment PANDA, at FAIR, GSI, the central detector and the inner silicon pixel and strip detector[1] will play an essential role in tracking charge particles, produced in the target. An antiproton beam of maximum 15 GeV/c momentum wi...

The potential of the high resolution nuclear track detector (NTD) CR-39 is examined carefully for the measurement of relativistic nuclear projectile fragmentation cross sections and studies of related processes using the experience of many years of such measurements. The charge resolution and the charge resolving power of CR-39 detectors for the measurements of 158 A GeV Pb projectiles and thei...

The present contribution describes the track reconstruction performance of the ATLAS Detector, based on the first proton-proton collisions delivered by the LHC accelerator at CERN at centerof-mass energies of 900 GeV and 7 TeV. The nominal tracking performance is first outlined in terms of expected track parameter resolutions and then the influence of the level of residual misalignment and of t...

in a detection network, the final decision is made by fusing the decisions from local detectors. the objective of that decision is to minimize the final error probability. to implement and optimal fusion rule, the performance of each detector, i.e. its probability of false alarm and its probability of missed detection as well as the a priori probabilities of the hypotheses, must be known. howev...

background: separate radon and thoron measurements in soil are very important in assessment of internal exposure due to inhalation of such radioactive gases. materials and methods: in this study, a low cost, small size, passive diffusion chamber has been developed for simple measurement of radon-222 and radon-220(thoron) gases separately in soil. the diffusion chamber consists of two films and ...

In this chapter, several advanced detection algorithms for Track-Before-Detect (TBD) procedures using the Hough Transform (HT) are proposed and studied. The detection algorithms are based on the scheme described in (Carlson et al., 1994) to use the Hough transform for simultaneous target detection and trajectory estimation. The concept described in (Carlson et al., 1994) accepts that a target m...

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...
