Research ArticleOpen accessIn the keywordsA Novel Interconnect Structure for Elmore Delay Model with Resistance-Capacitance-Conductance SchemeUma Ramadass, Krishnappriya, Jebashini Ponnian, P. DhavachelvanIn this brief, we present a simple close-form delay estimate, based on first and second order moments that handle arbitrary voltages and conductance effects for a lumped and distributed line. This proposed model introduces a simple tractable delay formula by incorporating conductance (G) into Resistance, Capacitance (RC) network by preserving the characteristics of the Elmore delay model. The RCG model … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,045 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermal Characterization of an Eco Conce Based on Lateritic Gravel, Millet Pods and CementDjossou Ayihaou Armand, Doko Kouandété Valéry, Wade Doukago Yacoubou Soumanou et al.To simultaneously meet the need of thermal confort and living environment protection, vegetable biomass valorisation in building sector is of particular importance. In this context, the main objective of this study is to produce a lightweight composite concrete based on millet pods and lateritic gravel with a cement matrix for use in buildings to help improve thermal comfort and protect … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 16 Sep 2021 · 6,489 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStatic and Dynamic Performance Improvement of Conventional Computer Numerical Control Machine Tool Bed with Hybrid Welded SteelS.S. Abuthakeer, P.V. Mohanram, G. MohankumarProblem statement: The advancements in machine tools to maximize the production by increasing spindle speeds have caused vibration in machine tools. The two functional requirements of machine tool bed for machine tools are high structural stiffness and high damping, which cannot be satisfied simultaneously if conventional metallic materials such as cast iron are employed. Hence there is a need to … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 11,479 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInteraction of Soil Static and Dynamic Stiffness and Buried Pipeline Under Harmonic VibrationAlireza Mirza Goltabar Roshan, Hossein Khalilpasha, Mohsen GhorbaniProblem statement: When earthquake is occur, many damages were occurred in pipelines that San Francisco (1906) and Manson (1908), Kobe (Japan) and ate are samples of this topic. So many researchers studied on the pipelines and dynamic forces. Approach: Determine static and dynamic performance parameters of the pipeline and the surrounding soil such as static stiffness, dynamic stiffness, damping and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,727 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effect of R/X Ratio of the Short Transmission Line on Transient StabilityPrechanon KumkratugProblem statement: The exact short transmission line model consists of the resistance and reactance. Most of previous researches study the transient stability of single machine infinite bus with neglecting the resistance of the line. Thus the simulation results may not close to the practical system. With the consideration with the actual short line model, it causes difficulty of deriving the … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 24 Jan 2012 · 8,057 accessesView PDF Cite
