The general purpose of the technical protection system and its composition are shown. necessity using security systems at objects information activity has been determined. existing method transmitting in loop is analyzed, shortcomings It proposed to use digital methods processing order counteract shortcomings.

Mechanical and electro-mechanical de-icing systems are low-energy ice protection solutions based on fracture mechanisms. It can, however, be difficult to obtain the of an entire surface due limited propagation fractures for some This article shows how it is possible reshape substrate in order favor adhesive at ice/substrate interface. The first part paper introduces analytical beam theory appro...

While ideally noise should be reduced at the source, in the military environment the most effective solution in terms of both cost and operational effectiveness has been to provide personnel with personal hearing protection. This protection may be in the form of either an earplug that occludes the ear canal or a circumaural protector that inserts a barrier between the ambient noise and the ear....

This paper summarizes an in-depth review of the US nuclear operating experience with the first generation of digital reactor protection systems. The accumulated operating experience from 1984 through 2006 on these first generation digital reactor protection system functions exceeds 1.27 million hours (~145.5 years). A review of failure event reports identified 141 specific events associated wit...

Security violations occur in systems even if security design is carried out or security tools are deployed. Social engineering attacks, vulnerabilities that can not be captured in the relatively abstract design model (as buffer-overflows), or unclear security requirements are only some examples of such unpredictable or unexpected vulnerabilities. One of the aims of autonomous systems is to reac...

This paper describes Metagap e, a formally speciied family of capability systems capable of restricting the transfer of both information and access rights. Previous work indicates that the identiication of such architectures is diicult, and in most cases their veriication is undecidable. To the best of our knowledge, Metagap e spans all real capability systems known to support the connnement pr...

The Universal Command and Control System (UCCS) is a highly distributed system involving numerous platforms and commands, supporting military operations worldwide. The Highly Reliable Software Production Facility (HRSPF), recently assigned responsibility for improving system performance, has generated routing algorithm update 3.01 to be installed in thousands of routers throughout the system, i...
