The operability of machine and tool parts is often determined by the state working surface. It on surface that cracks arise, wear corrosion processes begin. presence defects, degree depth hardening, level residual internal stresses, structure, nature transition to base material, most determine reliability service life structures. Based a critical review hardening methods, it was found one promi...

The state-of-art Li-ion batteries have revolutionized the portable electronic industry and first-generation electric vehicles due to their high energy density at ambient temperatures. Owing catastrophic failures under heat, these power devices are incompatible for applications such as in defence arsenals, subsurface drilling, space exploration medical appliances, where performance high-temperat...

This paper describes a technique for software safety analysis which has been developed with the specific aim of feeding into and guiding design development. The method draws on techniques from the chemical industries’ Hazard and Operability (HAZOP) analysis, combining this withwork on software failure classification to provide a structured approach to identifying the hazardous failure modes of ...

Systems for helping users to select data sources in an environment, such as the Internet, must be expressive enough to allow a variety of data sources to be formally represented. We build upon and extend the concept language, description logic (DL), to propose a novel representation system to achieve that goal. We point out that there are technical barriers within description logic limiting the...

The purpose of this study is to compare the author’s experience in founding and managing a company in Merida, Mexico to existing literature on cross-cultural management. The results should prove useful for non-Mexican managers working in Mexico and can provide a basis for devising empiricalbased research to test the ethnographic results reported. The author concludes that most of the discrimina...

The provision of Graphical User Interface (GUI) front-ends for legacy applications presents a number of engineering challenges. These can include language inter-operability problems and locating suitable hooks into the original application. These issues are further complicated for Internet front-ends which allow users to access an application remotely. This paper describes a project which addre...

This paper describes a design that addresses limitations inherent in the initial implementation of the Archive for the Earth Observing Systems (EOS). The design consists of two elements: a Request Manager client interface and a Thread Manager design pattern. In combination, these design elements provide dramatic improvements in reliability and scalability. Moving to a transaction processing-bas...
