Novel approaches are presented for structural damagedetection that use virtual passive controllers attached to structures, where passive controllers are energy dissipative devices and, thus, guarantee closed-loop stability. The use of the identiŽ ed parameters of various closed-loop systems can solve the problem that the reliable identiŽ ed parameters, such as natural frequencies, of the open-l...

Fields of distributed passive and multistatic active sonar sensors provide a surveillance capability against quiet submarine threats in ASW scenarios. A significant challenge of heterogeneous, multi-sensor systems is the successful fusion of information from the various sensors to enable robust target detection, classification, localization, and tracking. Sensor fusion and tracking algorithms m...

This paper reports a microchip with an integrated passive micromixer based on chaotic advection. The micromixer with staggered herringbone structures was used for luminol-peroxide chemiluminescence detection. The micromixer was examined to assess its suitability for chemiluminescence reaction. The relationship between the flow rate and the location of maximum chemiluminescence intensity was inv...

Falls are a significant problem for the elderly living independently in the home. Many falls occur due to household objects left in open spaces. We present KinSpace, a passive obstacle detection system for the home. KinSpace employs the use of a Kinect sensor to learn the open space of an environment through observation of resident walking patterns. It then monitors the open space for obstacles...

Failure of addressing all IEEE 802.11i Robust Security Networks (RSNs) vulnerabilities enforces many researchers to revise robust and reliable Wireless Intrusion Detection Techniques (WIDTs). In this paper we propose an algorithm to enhance the performance of the correlation of two WIDTs in detecting MAC spoofing Denial of Service (DoS) attacks. The two techniques are the Received Signal Streng...

An extensive growth in digital technology has resulted in tampering of image. Image plays an important role in today’s digital world. Powerful image editing tools has made it difficult to determine whether the image is authentic or forged. The main objective of this paper is to detect the forgery in which a part of the image is copied and pasted on to same image without the information of the o...

This paper investigates a robust signal detection scheme for the uplink communication in radio frequency identification systems. An optimum maximum-likelihood sequence detector (MLSD) scheme and a sub-optimum sliding correlation detection scheme are proposed for differential bi-phase codes. The MLSD scheme has 3 dB performance improvement w.r.t. the single symbol ML detector. However, these alg...

Recently, augmented ultrahigh frequency radio-frequency identification (UHF RFID) systems have been developed, and they contain additional components that can detect a tag’s backscattered response and use this information for the localization of the tag and other applications. The methods currently employed either have poor performance because the detection of the tag’s response is based on env...

This study presents a method to quantify a child's sensitivity to passive limb motion, which is an important aspect of kinaesthesia not easily examined clinically. Psychophysical detection thresholds to passive forearm motion were determined in a group of 20 typically developing pre-adolescent children (mean age 12y 6mo, SD 10mo, range 11-13y) and a group of 10 healthy adults (mean age 29y 10mo...

BACKGROUND Data on effect of regular liver function monitoring during anti-TB treatment is limited in China. This study aimed to evaluate the effects of scheduled liver function monitoring on identification of asymptomatic liver damage and anti-TB treatment outcomes during anti-TB treatment. METHODS A retrospective analysis was performed based on a national-level cohort study. A total of 273 ...
