This paper presents how to model technical and human errors and how the two error types are integrated in one common model. Human errors were modeled as an integral part of the organization’s ability to handle failures, while technical errors were embedded as an integral part of the oil well drilling operation. To reduce the number of offshore accidents there is a continuous focus on safety imp...

It is well known that the use of cache memory significantly improves the performance of a computing system. There exists a large quantity of technical literature dealing with analysis and design of cache-based systems. One of the most recent trends in computer technology is to implement multilevel caches. Today, most new processors implement an on-chip dual cache; one for instructions and one f...

In this article, the failure of a heat exchanger during its operation in the marine environment has been analyzed. This heat exchanger was used for cooling the oil in a marine diesel engine. Based on the existing failure history, damages in engine components were observed after 89 hours of engine working due to the leakage of the sea water to the oil. For the objective of the failure analysis, ...

Intuitively, a cache-oblivious algorithm implements an adaptive strategy which runs efficiently on any memory hierarchy without requiring previous knowledge of the parameters of the hierarchy. For this reason, cache-obliviousness is an attractive feature of an algorithm meant for a global computing environment, where software may be run on a variety of different platforms for load management pu...

A technique to analyze particulates extracted from inline jet engine oil filters using energy dispersive X-ray fluorescence (EDXRF) is presented. This technique, developed by the U.S. Department of Defense’s Joint Oil Analysis Technical Support Center (JOAP-TSC), is termed filter debris analysis (FDA). Six beta prototype instruments capable of performing FDA-EDXRF in an automated mode were manu...
