Please cite this article in press as: Kumar S doi:10.1016/j.microrel.2009.09.016 This paper presents an approach for selecting precursor parameters for health monitoring of electronic products. The approach includes failure modes, mechanisms, and effects analysis (FMMEA) and life cycle profile analysis of a product. The criticality of the failure mechanisms is established using a risk priority ...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
the paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (fmea). the approach is based on the ‘technique for order preference by similarity to ideal solution’ (topsis). the priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
This paper presents a model-based fault detection and isolation scheme for the transmission components of Electro-Mechanical Actuators, applied to actuation sliding gates. The most important failures are investigated by Failure Mode, Effects, Criticality Analysis procedure. Following Analysis, selected development diagnostic algorithm nylon gear pinion Actuator, rack gate. proposed is able isol...
Weldability of high carbon steels due to the high percentage of carbon and consequently formation of martensitic structure is very poor. In this research, resistance spot welding of eutectoid high carbon steel 1075 is experimentally and numerically investigated from various points of view. The effect of welding current as one of the most effective parameters on failure mode, mechanical properti...

We present a new graph-based real-time task model that can specify complex job arrival patterns and global statebased mode switching. The mode switching is of a mixedcriticality style, enabling immediate changes to the parameters of active jobs upon mode switches. The resulting task model therefore generalizes previously proposed task graph models as well as mixed-criticality (sporadic) task mo...
This paper presents an original method for risk assessment in water treatment, based on belief functions. The risk of producing non-compliant drinking water (i.e., such that one of the quality parameter exceeds the regulation standards), is estimated taking into account the quality parameters of raw water and the process line of the treatment plant (technology, different failure modes and corre...
