On Some Quality Issues of Component Selection in CBSD

Journal of Software Engineering and Applications 2010年第6期3卷 556-560页

作者： Jeetendra Pande raj kishore bisht Durgesh Pant Vinay Kumar Pathak 不详

Component based development offers many potential benefits, viz. software reuse, reduced time-to-market, inter- operability, ease of quality certification etc. However, it is not always that benefits derived from addition of components from a component repository are more than the costs involved in developing the module from scratch. This work evaluates various software quality models and suggests recommendations for enhancing software quality in COTS (component off-the-shelf) based software products by designing software quality metrics that would help in managing and enhancing quality in component-based software development.

Surface and Bulk Defects in Cr-Mn Iron Alloy Cast in Metal and Sand Moulds: Characterization by Positron Annihilation Techniques

引用

Journal of Surface Engineered Materials and Advanced Technology 2011年第3期1卷 136-143页

作者： Parthasarathy Sampathkumaran Subramanyam Seetharamu Chikkakuntappa Ranganathaiah Jaya Madhu raj Pradeep Kumar Pujari Priya Maheshwari Debashish Dutta S. kishore 不详

High chromium (Cr: 16% - 19%) iron alloy with 5% and 10% manganese (Mn) fabricated in metal and sand moulds by induction melting technique were investigated for defects microstructure both in the as-cast and heat treated conditions. Non-destructive techniques namely Positron Lifetime Spectroscopy and slow positron Doppler Broadening studies were employed to characterize the defects in the bulk as well as surface of the alloy and their influence of metallurgical parameters. The Positron Lifetime Spectroscopy data reveals that the defect concentration is higher for sand mould alloy samples compared to metal mould ones. The reasons for fewer defects in metal mould are attributed to faster heat transfer in the metal mould. Further, heat treatment yielded spherodization of carbides in the matrix resulting in reduced defects concentration. The S-parameter profiles from Doppler Broadening studies suggest defect concentration at the surface is less in 5% Manganese and near absence of any modification of defect structure following heat treatment in 10% Manganese sample closer to surface.
