Various mine detection techniques are reviewed with particular emphasis on signal and image processing methods. Based on the target, mines are classified into two types; anti-tank mine (ATM) and anti-personnel mine (APM). Because of the variety of mine types, current mine detection techniques are diversified. The assumption is made that most mine detection techniques consist of sensor, signal p...

In this work, a safe Coal Mine Monitoring system which replaces the traditional coal mine monitoring systems which tend to be wired network systems. This play an important role in coal mine safe production. With continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, where are lots of hidden dangers. Moreover, it is inconvenient...

Researchers have worked on routing issues for adhoc-networks, VANET’s, and Wireless Sensor Networks in a normal scenario; recently there has been a recent trend towards the study on underground wireless networks and proposals for design and development for Wireless Underground Sensor Networks. This paper highlights the concept of wireless underground sensor network in the coal mine environment,...

Neurons receive synaptic inputs primarily onto their dendrites, which filter synaptic potentials as they spread toward the soma. Recent results indicate that this filtering appears to be compensated by increasing the synaptic conductance at distal synapses, thus normalizing the efficacy of synaptic inputs at the soma.

Strain is an important parameter for assessing the potential impacts resulting from mine subsidence movements. However, strain resulting from mine subsidence is also one of the most difficult parameters to predict accurately. A number of methods can be used to predict strain, from simple empirical relationships, to more complex statistical approaches. This paper looks at some of these predictio...

Hobert Knox, m.d. (Edin.), m.r.c.s. (Eng.), l.r c.p (Lond ), etc. Part II. Radio-Therapeutics. Tbie first edition of the work of which this book is Vol. II of the second edition, at once made its mark as a work of reference for the practical worker in a branch of therapeutics which is teeming with interest and suggestive of great possibilities. There is a good deal of new matter in this edition...

RESULTS. Optic nerve injury produced a significant decrease in the soma, dendritic field size, and dendritic complexity of cells. Cells also displayed a significant decrease in soma size, but their dendritic fields were not affected as severely as those of cells. Intravitreous treatment of the eye with BDNF at the time of injury preserved the normal somal and dendritic morphologies of both and ...

For two-compartmentmodels: the integrate-and-"remodel and the Pinsky}Rinzelmodel, we show that the smaller the soma is, the faster and the more irregularly the neuron "res. We also "nd that when the soma is small, two-compartment models can be naturally employed as slope detectors. 2001 Elsevier Science B.V. All rights reserved.
