Six Sigma Methodology Utilization in Medical Transcription-A DMAIC Process to Identify Six Sigma Projects
Six-sigma is a business-driven, multi-faceted approach to process improvement, reduced costs, and increased profit. It helps to improve quality of product and cost saving. Six sigma is considered to be one of the best quality improvement methodology applied successfully to organizational areas like manufacturing, production, accounting and finance, sales and marketing, information systems, huma...
متن کاملAssessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.
Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
متن کاملReactivity in Recycled Concrete Aggregate
Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...
متن کاملPerformance and Implementation of Low-Quality Recycled Concrete Aggregate
Our project seeks to greatly reduce the energy required for concrete production by using mostly recycled concrete. The use of recycled concrete aggregate (RCA) is not a new phenomenon, but has not been studied in the context of low-cost disaster reconstruction efforts, which was our focus—specifically, the 2010 earthquake in Haiti. In our experiments, we sought to replicate the variability in c...
متن کاملAn Experimental Investigation of Using Recycled Aggregate in Concrete
One of the major challenges of our present society is the protection of environment; with respect to this some of the important elements are reduction of natural raw materials and consumption of waste materials. The recycled aggregate sample of size 20mm which is the maximum size of aggregate in reinforced cement concrete is collected from demolished structures in our surrounding areas and the ...
