Crystal-damage events such as tracks and point defects have been used to record detect radiation for a long time recently they proposed means dark-matter detection. Color centers can be read out optically we propose scheme based on selective plane illumination microscopy micrometer-scale imaging of large volumes corresponding kilogram mass detectors. This class detectors would passive operate a...

Today manipulation of digital images has become easy due to powerful computers, advanced photo-editing software packages and high resolution capturing devices. Verifying the integrity of images and detecting traces of tampering without requiring extra prior knowledge of the image content or any embedded watermarks is an important research field. An attempt is made to survey the recent developme...

Context. Passive testing is a technique in which traces collected from the execution of a system under test are examined for evidence of flaws in the system. Objective. In this paper we present a method for detecting the presence of security vulnerabilities by detecting evidence of their causes in execution traces. This is a new approach to security vulnerability detection. Method. Our method u...

Object detection is the automatic determination of image locations at which instances of a predefined object class are present. Numerous methods for object detection exist (e.g., (Viola and Jones, 2001; Fergus et al., 2006)), most of which scan a part of the image at some stage of the object-detection process. Until now, this scanning is performed in a passive manner: local image samples extrac...

In this paper we investigate the dynamic range requirements of a passive radar system and show the impact of analogto-digital converter (ADC) quantization on system performance. This analysis is carried out with a view towards understanding how many ADC bits are required in each channel of the passive radar system. To give practical insight, we consider the parameters of a passive radar system ...

In this paper, we employ the Communicating finite state machine (CFSM) model for networks to investigate fault management using passive testing. First, we introduce the concept of passive testing. Then, we introduce the CFSM model, the observer model and the fault model with necessary assumptions. We introduce the fault detection algorithm using passive testing. Then, we briefly present our new...

Three assays for detection of rubella antibodies, Rubella G (fluorescence immunoassay [FIA]), Rubacell (passive hemagglutination), and Rubaquick (passive hemagglutination with rotation), were compared with hemagglutination inhibition. A total of 100 serum specimens were selected, 68 of which had an FIA value of less than or equal to 25. On initial testing, among the four tests, there was agreem...

Cognitive radio (CR) is an enabling technology that helps efficiently use spectrum. In this paper, a collaborative spectrum sensing mechanism is proposed which combines passive detection and sensing service compensation. Theoretical analysis and simulations show that this method not only reduces the energy cost and the passive sensing time, but also maintains fairness in the CR communication sy...
