This literature reviews the work of researchers on ground-penetrating radar (GPR). research consists five sections starting from first section that focuses general application and advantage GPR system in comparison to other types underground detection systems.
 The main function is detect object buried at end full scan, output image represents total signals detected by receiver device. One...

In the development of geophysical methods for unexploded ordnance detection, a very important role is played by UXO test sites, where known and other explosive/nonexplosive items are buried in ground at defined positions. At such various detection can be compared, developed tested. Based on cooperation between Department Applied Geophysics (Comenius University), Institute Forensic Science (Slov...

-Detecting subsurface objects by using GroundPenetrating Radar (GPR) has received considerable interest in recent years. In order to interpret radar signals from buried objects, one must have the ability to model a large range of objects, grounds and radar antennas, theoretically or numerically, so that a real GPR system can be simulated. Many investigations have been done for modeling objects ...

This paper presents GPR (Geographic Probabilistic Routing protocol), an opportunistic routing protocol worked between mesh routers in WMNs (Wireless Mesh Networks). In GPR, nodes detect the link condition by probe packets. In order to send a packet, the sender selects a candidate subset. The nodes who successfully received the packet send ACK according to their priority. If there are no ACKs fr...

The primary objective of the work-in-progress reported here is to compare near-surface imaging results using ultra-shallow (upper 3 m) seismic-reflection techniques and ground-penetrating radar (GPR) at an alluvial site near Great Bend, Kansas. Although various seismic and GPR surveys have been used for near-surface imaging, little i s known about how the two techniques might work in concert fo...

However, GPR fails to note that a very similar result giving lqǫ-security was proved earlier in our paper “Another look at HMAC.” GPR acknowledges our main theorem, which gives lǫ-security under a stronger PRF-assumption, but omits any mention of our Corollary 10.3, where we proved that lqǫ-security under the weaker assumption follows from the theorem. GPR can correctly claim that their result ...

Directional decomposition of GPR data is possible when multi-component multi-offset GPR data is available on a surface. The decomposed wave fields are propagating in the two opposite directions perpendicular to the recording surface. These two decomposed wave fields are related to each other through a reflection operator. This operator represents the reflection response of the medium on the sid...

Despite differences between public and private sectors, business process reengineering (BPR) principles have been widely used in reengineering government processes. This has led to a growing body of literature on government process reengineering (GPR). This chapter presents synthesis and analysis of the literature on government process reengineering from 1997 to 2009. It reviews normative studi...

Asymmetric divisions are crucial for generating cell diversity; they rely on coupling between polarity cues and spindle positioning, but how this coupling is achieved is poorly understood. In one-cell stage Caenorhabditis elegans embryos, polarity cues set by the PAR proteins mediate asymmetric spindle positioning by governing an imbalance of net pulling forces acting on spindle poles. We found...
