ace detector, object detector, integration, expected computational cost, cascade of classifiers, decision tree This paper describes a method for integrating object detectors that reduces the expected computational cost of evaluating all the detectors whilst obtaining the same logical behaviour as running the detectors independently. The method combines the decision trees of the different object...

Bunch shape is one of the most important and interesting characteristics of a beam in ion linear accelerators. Recently detectors of bunch shape with a transverse scanning of low energy secondary electrons found application in several accelerators. The principle of operation of the detectors is based on a coherent transformation of a longitudinal structure of a beam under study into a transvers...

It is a challenging problem to detect partially occluded pedestrians due to the diversity of occlusion patterns. Although training occlusionspecific detectors can help handle various partial occlusions, it is a nontrivial problem to integrate these detectors properly. A direct combination of all occlusion-specific detectors can be affected by unreliable detectors and usually does not favor heav...

Background and Objective: Radon is a radioactive, odorless gas. Radon gas with the emission of alpha radiation and sticking to aerosols in the air can cause lung cancer. This study evaluated the concentration of radon in residential houses and public places in Firuzkuh city and compared the values with the recommended international guidelines. Materials and Methods: Radon gas concentration was...

The radioactive contamination measurement is essential in nuclear facilities. Monitoring of low level alpha and beta contamination is possible using light detectors high efficiency. Due to the fact that many detectors canchr('39')t simultaneously discriminate alpha, beta and gamma rays; among existing methods, phoswich detectors would be appropriate option to measure different radioactive conta...
