Background: A Boron Neutron Capture Therapy (BNCT) facility, based on a DT neutron generator, with the final goal to find out a potential, alternative, solution to existing BNCT treatment facilities which are based on nuclear reactors is examined. Materials and Methods: With the aim of the MCNP4B Monte Carlo code different beam-shaping assembly (BSA) configurations were considered. Lead was sel...

This paper proposes a general mixture model framework for automobile warranty data that includes parameters for product field performance, the manufacturing and assembly process, and dealer preparation process. The model fits warranty claims as a mixture of manufacturing or assembly defects (quality problems) and usage related failures (reliability problems). The model also estimates the fracti...

In recent years, the management issue in the Japanese automobile industry playing a key role in Japanese manufacturing is “worldwide uniform quality and simultaneous production launch,” in response to current globalization. In this corporate management environment, the “key to success in global production” is the reinforcement of product power, or the “simultaneous achievement of QCD.” In order...

Variations in parts and tooling are a major problem in automobile body assembly processes. Those discrepancies adversely affect body assembly quality, functionality, cost and time-to-market. Variation simulation analysis has been used in the design stage to predict such uncertainties, but variation analysis based on rigid body assumptions usually yields over-estimates of the assembly variations...
