This paper describes a forensic logging system that collects fine-grained trace evidence from target servers and networks. To provide a more reliable and efficient forensic logging system, we developed a dedicated network processor that collects network traffic and a hardened TCSEC-B1 level secure operating system. The system also is capable of defending servers from malicious attacks as well a...

In this paper we are focusing on secure logging for public network providers. We review existing security threat models against system logging and we extend these to a new threat model especially suited in the environment of telecommunication network providers. We also propose a framework for secure logging in public communication networks as well as realistic implementations designs, which are...

Abstract During the conventional petrophysical interpretation fixed (predefined) zone parameters are applied for every (depth intervals). Their inclusion in inversion process requires extension of a likelihood function whole zone. This allows to define extremum problem fitting parameter set full interval model layers crossed by well, both associated with depth points (e.g. porosity, saturations...

PROBLEM It is well documented that logging is one of the most dangerous occupations and industries in which to work, and trees fellers are at greatest risk of injury. The objective of this study was to determine whether West Virginia (WV) logging companies experienced a reduction in injuries after beginning to use feller-bunchers (tree cutting machines, which replace some of the work done with ...

As the exploration of ultra-deep layers and development geothermal resources continue, obtaining more accurate downhole parameters becomes increasingly important. Flow measurement, in particular, is a complex parameter that presents significant challenges. In order to enhance accuracy turbine flow logging tool, this research focuses on optimizing metering structure through range methods. A calc...

In this article we present a novel method for the estimation of sulphur deposit resources based on high-resolution shallow reflection seismic survey and well logging. The study area was sited in northern part Carpathian Foredeep (SE Poland), where ore occurs carbonate rocks at depth about 120 m, with thickness approximately 25 m. results many years monitoring performed allowed us to determine q...
