Detection of explosives has the flavor of those mathematical problems that are not invertible. It is easier to hide explosives than to find them. Many approaches have been proposed and executed for the remote detection of explosives, contraband materials, weapons of mass destruction, currency, etc. Most detection technologies suffer from a common problem: the features they look for, such as dis...

In this paper, we obtain the Complex Natural Resonances of an object from backscattered response in frequency domain with a novel rational function approximation method based on both Vector Fitting and Cauchy methods. We determine system order initial set poles, which are used as basis for approximation. The results simulations experiments show improvement reconstructed signals accuracy CNRs ca...

Understanding of human expertise and its acquisition has progressed substantially since Chase & Simon’s seminal studies of chess expertise. Computational theories of expertise have been developed in domains such as memory, mental calculation, chess, and problem solving that explain expert performance at the level of cognitive structures and processes. Basic and use-inspired studies have demonst...

Statistical Analysis of Landmine Fatalities in Kurdistan This study analyzes mines and unexploded ordnance (UXO) victim data in the Kurdistan Region of Iraq during the period of the 1960s to 2005. In addition to descriptive analysis of the data, we use regression analysis to identify the determinants of the probability of getting killed by a mine or UXO and to estimate the determinants impacts....

According to the United Nations, as of the year 2000 there were 70 million landmines planted in a third of the world’s nations affecting global causality rate of up to 20,000/year, (Anderson, 2002). That is why landmine detection has attracted much attention by many research teams around the world during the last two decades; among them is our research team in Nagoya University. Anti-personnel ...
