A computational efficient approach to identify very small mine-shaped plactic objects, e.g. M56 AntiPersonnel (AP) mines buried in the ground, is presented. The size of the objects equals the smallest AP-mines in use today, i.e., the most difficult mines to detect with respect to humanitarian mine clearance. Our approach consists of three stages, the phase stepped-fiequency radar method, genera...

Many studies have shown that our visual system may construct a “statistical summary representation” over groups of visual objects. Although there is a general understanding that human observers can accurately represent sets of a variety of features, many questions on how the statistical summary is computed still remain unanswered. This study investigated sampling properties of visual informatio...

Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...

-EMAP5 is a numerical software package designed to model electromagnetic problems. It employs the finite element method (FEM) to analyze a volume, and employs the method of moments (MoM) to analyze the region exterior to the FEM volume. The two methods are coupled by enforcing the continuity of the tangential fields on the interface. Dielectrics, lossy dielectrics and metal objects can be model...

hanna mina is considered as  one of the realist writers. he achieved fame in syria by his first novel al-masabih al-zorq (1945) and in his later works introduced himself as a prolific and talented writer.he was different from the others because the subject of his novels was life problems and he believed that realism can embrace other literary schools  such as  romanticism and symbolism. this ap...

Abstract The present paper analyses the precious metal artefacts, scarcely known in huge archaeological material of “late Avar period” (eighth to early ninth centuries AD). Unlike previous era majority gold and silver objects late period are stray finds; particular high-quality goldsmith's artefacts absent grave assemblages eighth century. significance reached its low ebb around middle period; ...

Abstract. Technological knowledge of the use metals is inseparable from human in processing pyrotechnics fire as a power high temperature processes for producing objects. The used smelting and casting melting furnaces. Metal furnace heat production device, which to purify metal, this case iron. This paper aims determine development ferrous metal technology Indonesia with library research method...

Guns and knives have imposed a significant threat to public safety. Based on the electromagnetic characteristics of the materials of guns and knives’, techniques concerning Electromagnetics (EM) e.g. walk-through metal detection equipment and X-ray and THz screening system have been used in an effort to detect and characterise them. Different EM frequencies for metallic object detection have de...
