Non-imaging sensors offer low power and long lasting solutions for perimeter, border crossing, and forward operating base protection. In this paper, we study the utility of acoustic, seismic, and ultrasonic transducers for detection and identification of people and animals. Various algorithms will be developed for them, which are computationally less(More)
Seismic sensors are widely used to detect moving targets in the ground sensor network, and can be easily employed to discriminate human and quadruped based on their footstep signatures. Because of the complex environmental conditions and the non-stationary nature of the seismic signals, footstep detection and classification is a very challenging problem.(More)
BACKGROUND Both ALT/AST ratio reversal (AST/ALT > 1) and prolonged prothrombin time are separately related to hepatic cirrhosis. Ratio reversal means that in normal individuals ALT is more than AST and thus ALT/AST > 1 but with development of cirrhosis AST becomes > ALT and so AST/ALT > 1 or ALT/AST < 1. This study was conducted with the idea that prolonged(More)
Software (SW) development is a very tough task which requires a skilled project leader for its success. If the project leader is not skilled enough then project may fail. In the real world of SW engineering 65% of the SW projects fail to meet their objectives as in [1]. The main reason is lack of training of the project mangers. This extreme ratio of(More)
—This paper describes a new kernel wavelet-based anomaly detection technique for long-wave (LW) Forward Looking Infrared (FLIR) imagery. The proposed approach called kernel wavelet-RX algorithm is essentially an extension of the wavelet-RX algorithm (combination of wavelet transform and RX anomaly detector) to a high dimensional feature space (possibly(More)
