This is the final project report for the NSF Division of Network and Communications Research and Infrastructure Grant NCR-93-01002, funded from June 1993. It is also a quartely project report for DARPA Information Technology Office Contract DABT 63-95-C-0046 The principal goal in the combined research program is the continued improvement in analysis, design, implementation, deployment and manag...

THE CSNET PHOJECT, sponsored by t,he National Science Foundaton, has as its goal the design and implementation of a computer communications network to provide services to computer science research groups in the United States Experience with Arpanet has shown that access to a computer network can lead to a significantly higher level of interactlion between geographically dispersed researchers. T...

geological facies interpretation is essential for reservoir studying. the method of classification and identification seismic traces is a powerful approach for geological facies classification and distinction. use of neural networks as classifiers is increasing in different sciences like seismic. they are computer efficient and ideal for patterns identification. they can simply learn new algori...

The book gives an extensive overview of network security and the necessary cryptography. It covers standards and protocols in great detail, and can serve as a handy reference for people interested in this area. Due to the many exercises, it can also serve as one of the textbooks of an introductory course on network security. 1 What the book is about The book is intended as a textbook for a one-...

The need for multilevel security in computer systems has become well known. In the military, lacking such systems makes costs higher than they should be because of the need either to replicate facilities or perform "color changes" (shutting down and purging systems between uses at varying levels) in order to deny less-cleared users access to highly-classified information, and desirable function...
