Hardfacing is an efficient and economical surfacing technique widely used by heavy industries to remediate worn components in service or enhance the component’s wear characteristics prior use. Efficient hardfacing for any targeted application requires precise consideration understanding of deposition process, consumables, substrates. It also essential understand process variables issues that ca...

Ala~traet--Errors-in-variables problems are considered for the case of three variables, where the underlying relations among the noise-free variables are linear, and covariance information for the noisy variables is available. The static problem where the variables are complex (which can arise when narrowband filtering is used) is analysed in detail. Some results are also presented for the case...

Standard BPEL (Business Process Execution Language) variables, if used to store the data from a data store, cannot be automatically synchronized with the data source in case other applications change the data during the BPEL process execution, which is a common occurrence particularly for long-running BPEL processes. BPEL also does not provide a mechanism for active monitoring of changes of dat...

in this study, a hybrid algorithm is presented to tackle multi-variables robust design problem. the proposed algorithm comprises neural networks (nns) and co-evolution genetic algorithm (cga) in which neural networks are as a function approximation tool used to estimate a map between process variables. furthermore, in order to make a robust optimization of response variables, co-evolution algor...

The intention of this paper is to provide an analysis of variables that could affect the adoption of HL7 message standard. Based on the review of 33 cases where HL7 was successfully implemented the authors present relevant evidence related to inherent limitation of HL7. The result from this study indicates that it is necessary to enhance the standard to overcome particular limitations and facil...

When an abrasive mixed with a polymer of special rheological properties and forced through a restricting medium, the abrasive and polymer will act as a self forming tool that precisely removes work piece material and improve the surface finish at those areas restricting to the medium flow. It is capable of machining areas which are difficult to reach by conventional machining and can be used to...
