background: occupational and environmental exposures mostly represent mixtures of genotoxic agents, whereas the specificity of biomarker measurements varies widely. exploration of correlations among biomarkers contributes to the further progress of molecular cancer epidemiology and to the selection of the optimal biomarkers for the investigation of human exposure to carcinogens. the aim of this...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...

This research aims to gain a detailed understanding of data producers, data consumers and format/flow of the data within automotive industry for defining and using Bill of Process (BoP) for engine assembly lines. The focus remained on the real industrial challenge of rapid constraint evaluation for designing and/or reconfiguration of Powertrain assembly lines to cater for a new/changed product....

The electronics computer-aided process-planning (ECAPP) system is a rule-and frame-based generative process-planning system for the assembly of electronic components onto printed circuit boards (or modu-less). ECAPP uses expert process-engineering knowledge, a manufacturing plant's specific process capabilities, and product information from a computer-aided design (CAD) database to generate all...

As resource scarcity and environmental degradation has aroused global concern, new energy vehicles have become the developing trend of automobile industry all over the world. However, there is lack of incentive for innovations on more environmentally friendly automobile technology. This paper introduces endogenous and directed technology progress into the growth model to analyze the decision-ma...

In order to safeguard the future of Chinese automobile industry, and maintain and strengthen its acceptance in Chinese community, it should be made a commitment to sustainability. The approaches to sustainability in Chinese automobile industry should comprise three aspects: nature conservation, production-related environmental protection and “5R” implementation which is considered as sustainabl...

We present a proof of correctness in Matita for an optimising assembler for the MCS-51 microcontroller. The efficient expansion of pseudoinstructions, namely jumps, into machine instructions is complex. We isolate the decision making over how jumps should be expanded from the expansion process itself as much as possible using ‘policies’, making the proof of correctness for the assembler more st...

The present work adopted Reliability Centered Maintenance (RCM) methodology to evaluate marginal oilfield Early Production Facility (EPF) system properly understand its functional failures and develop an efficient maintenance strategy for the system. outcome of RCM conducted a typical EPF within Niger Delta zone Nigeria provides indication equipment whose failure can significantly affect operat...

An engine bracket is one of the most critical components used for mounting and supporting in vehicles. Today, automobile industry requires lightweight components, which will reduce car's overall weight when fitted into vehicle. Topology optimization a technique with help surface component optimized to get required shape having reduced weight. The by optimizing material on details. In this paper...
