Research ArticleOpen accessIn the abstractImproving the Polypropylene-Clay Composite Using Carbon Nanotubes as Secondary FillerSalawudeen T. Olalekan, Suleyman A. Muyibi, Qasim H. Shah et al.Problem statement: Current researches have shown that the thermoplastic-clay nanocomposites have failed to live up to the earlier predictions albeit they have found some niche area of applications. This research work therefore aimed at studying the effect of carbon nanotube as secondary filler on the mechanical properties of polypropylene-clay nanocomposite. Approach: Hybrid polypropylene-clay nanocomposite was prepared in the presence of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractPullout Characterizations of Various Steel Fibers Embedded in Very High-Strength ConcreteSameer Hamoush, Taher Abu-Lebdeh, Toney Cummins, Brian ZornigProblem statement: There is a real need for a fundamental understanding of bond and bond mechanisms in the newly developed Very-High-Strength-Concrete (VHSC) materials. The interfacial steel fiber/VHSC matrix bond tests are needed to characterize VHSC and to aid in the development of analytical models that describe bond behavior of this new material. Approach: This research investigated bond-slip characteristics of four … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Large Block Cipher Using Modular Arithmetic Inverse of a Key Matrix and Mixing of the Key Matrix and the PlaintextV. U.K. Sastry, S. Udaya Kumar, A. Vinaya babuIn this paper, we have developed a block cipher by applying an iterative method. In the process of encryption, we have used a key matrix (K) in which all the elements are binary bits. In the process of decryption, we have utilized the modular arithmetic inverse (K-1). In the process of encryption, the elements of the plaintext and the elements … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,796 accessesView PDFCite

In this study, Rice husk fiber Reinforced Polyethylene composites (RhRP) have been fabricated with rice husk fiber and plastic waste (recycle low density polyethylene) by compression molding method. Effect of fiber volume fraction, pressure and temperature on the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 7,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalibration Coefficients for Residual Stress Measurement in Composite Materials Using Finite Element MethodA. G. Ghasemi, M. AkbarzadehProblem statement: Since the residual stresses can cause a scienificant reduction in strength of the mechanical components, having a semi-destructive measuring method that would predict and model theses stresses would be an advantage. The hole drilling method has been used, by many researches, for measurement of the residual stresses in different materials. In this article, the finite element method is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 18 Feb 2012 · 9,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Computable General Equilibrium Model of Southern Region in Taiwan: The Impact of the Tainan Science-Based Industrial ParkChun-Chu Liu, Chia-Yon ChenThe primary modeling tools used to analyze regional economic issues include econometric forecasting models, fixed price Input-Output (I-O) multi-sector models, Social Accounting Matrix (SAM) and Computable General Equilibrium (CGE) models. CGE models combine the advantages of econometric, I-O models and SAM strengthening the theoretical basis of the modeling effort and thus enabling more precise policy analysis. The current CGE literature … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,210 accessesView PDFCite
