Although a small number of landmines were introduced into modern warfare during World War I, the tactics of landmine use, both in the deployment and removal, did not become clear until World War II. By 1939, the German and Italian armies had developed both antitank and antipersonnel landmines, which were used effectively against the Allied forces. Naturally, the Allies developed techniques for ...

Ultra-wideband synthetic aperture radar (UWB SAR) is a sufficient approach to detect landmines over large areas from a safe standoff distance. Feature extraction is the key step of landmine detection processing. On the one hand, the feature vector should contain more scattering characteristics to discriminate landmines from clutters; on the other hand, the dimensionality of feature vector shoul...

Blast injuries are divided into four classes, and inhalation a quaternary class of blast injuries. An injury can be critical to the patient due possibility related complications, such as airway obstruction resulting from upper edema pneumonia. Once diagnosed, an should treated with early intubation, aerosol therapy, antibiotics soon possible. We suspect this in circumstances involving fire espe...

A numerical model for computing scattering from a three-dimensional (3-D) dielectric object above or below a rough interface is described. The model is based on an iterative method of moments solution for equivalent electric and magnetic surface current densities on the rough interface and equivalent volumetric electric currents in the penetrable object. To improve computational efficiency, the...

Mobile robots are increasingly used in automated industrial environments. There are also other applications like planet exploration, surveillance, landmine detection, etc. In all these applications, in order that the mobile robots perform their tasks, collision-free path planning is a prerequisite. This article provides an overview of the research progress in path planning of a mobile robot for...
