Research ArticleOpen accessIn the abstractSharp Transition Multiband Filter in Speech Processing Scheme for Hearing ImpairedJoseph X. Rodrigues, Lucy J. Gudino, K. R. PaiProblem statement: A simple analytical approach to the synthesis of a sharp transition, linear phase, multiband FIR filter is presented. The filter magnitude response is modeled using trigonometric functions of frequency. Approach: Employing variable density of ripple cycles in passband and stopband regions with large density of ripples cycles at the sharp transition edges, reduces the abrupt discontinuities at these … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 27 Feb 2012 · 9,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractMachining Performance Study on Metal Matrix Composites-A Response Surface Methodology ApproachA. Srinivasan, R. M. Arunachalam, S. Ramesh, J. S. SenthilkumaarProblem statement: Metal Matrix Composites (MMC) have become a leading material among composite materials and in particular, particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element-like Alumina (Al2O3). Approach: In this study, an attempt has been made … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 8,017 accessesView PDFCite
