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...

MANET is developing the next generation wireless universe. However MANETS prove their performance only when routing is efficient. In this paper we propose a model of Dedicated Trust System (DTS) which aims in detecting the misbehaving nodes. We implement our DTD using zone routing protocol with trusted systems. We finally develop a reputation model with two new parameters trustee and bucy trust...

Institute of Fundamental Research in Mumbai, India. The Institute currently has a 20 terawatt (TW), 30 femtosecond (fs) table top chirped pulse amplifi cation (CPA) titanium -sapphire laser facility and will have a fully functional 100 TW, 25 fs facility by the middle of 2011. This upgradation would propel existing research at the Institute to address ultraintense lasermatter interaction studie...

In software development life cycle, maintenance phase is an important phase as it deals with the activities like error correction, upgradation, deletion and optimization of software capabilities. For this reason, regression testing is required in order to revalidate the modifications in the software. It is an expensive process. Various techniques of performing regression testing are available. ...
