Purpose – Castings defects are usually easy to characterize, but to eradicate them can be a difficult task. In many cases, defects are caused by the combined effect of different factors, whose identification is often difficult. Besides, the real non-quality costs are usually unknown, and even neglected. This paper aims to describe the development of a modular tool for quality improvement in fou...

An electrochemical analysis on a single channel PEM fuel cell was carried out by Computational Fuel Cell Dynamics (CFCD). The objective was to assess the latest developments regarding the effects of change in the current collector materials, porosity of electrodes and gas diffusion layer on the fuel cell power density. Graphite, as the most applicable current collector material, was applied fol...

Methodology. In work, X-ray qualitative quantitative analysis was performed Rigaku Ultima IV unit, differential thermal STA 449 C Jupiter synchronous analyzer. Orthophosphoric acid, technical t...

Six Sigma is an organized & systematic method for strategic process improvement that relies on statistical & scientific methods to reduce the defect rates and achieve significant quality upgradation. A case study is carried out for a foundry, where Six Sigma methodology is implemented for the defect reduction. The optimized parameters are considered to perform the practical run for the differen...

Abstract Logic gates are fundamental components of integrated circuits, and integration strategies involving multiple logic advanced materials have been developed to meet the development requirements high-density circuits. However, these still far from being widely applicable owing their incompatibility with modern silicon-based foundry lines. Here, we propose a silicon-foundry-line-based multi...
