Research ArticleOpen accessPhrase in the titleKey Factors in the Face Stability Analysis of Shallow TunnelsDaniel Dias, Pierpaolo OresteStability of the excavation face in shallow tunnels and in poor ground is at present a relevant problem in tunnelling. A new calculation procedure is illustrated in this study for the analysis of the effect on the face stability in shallow tunnels of the following key factors: pre-support structures, presence of groundwater, free length of the tunnel (length of the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,017 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleKEY FACTORS FOR IMPROVING TECHNICAL EFFICIENCY OF UPLAND RICE PRODUCTIONThanaporn Athipanyakul, Panusak Jitsaeng, Napa Pongkapan, Piansak PakdeeFood security problems are major issues in developing countries, especially under the conditions of restricted farm resources and environmental degradation. The re-allocation of existing farm resources in the upland in order to reach a production of maximum output under given technologies and the estimated value of the technical efficiency have been important information for this purpose. The objective of this … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 24 Dec 2013 · 7,286 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleKey Success Factors of 3rd Generation Mobile Network Services for M-Commerce in MalaysiaSaravanan MuthaiyahWhile there has been a great deal of excitement in view of M-commerce, very little is actually known about conditions and critical success factors for successful introduction of the 3rd generation mobile network services here in Malaysia. This study investigates the factors for successful diffusion of 3G network services and their role in advancing an interactive marketplace. 3G which simply … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,876 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePDX-1 and MafA: Key Transcription Factors in PancreasHideaki Kaneto, Takeshi Miyatsuka, Yoshihisa Nakatani, Taka-aki MatsuokaPancreatic and duodenal homeobox factor-1 (PDX-1) plays a crucial role in pancreas development, β-cell differentiation and in maintaining normal β-cell function by regulating several β-cell-related genes including insulin. PDX-1 has potency to induce insulin-producing cells in non β-cells in various tissues such as pancreas and liver and PDX-1-VP16 fusion protein more efficiently induces insulin-producing cells, especially in the presence of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 7,389 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInteger Factorization: Solution via Algorithm for Constrained Discrete Logarithm ProblemBoris S. VerkhovskyProblem statement: During the last thirty years many public-key cryptographic protocols based on either the complexity of integer factorization of large semiprimes or the Discrete Logarithm Problem (DLP) have been developed. Approach: Although several factorization algorithms with sub-exponential complexity have been discovered, the recent RSA Factoring Challenge demonstrated that it was still necessary to use several thousand computers working in … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Dec 2009 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCERTIFICATE AUTHORITY SCHEMES USING ELLIPTIC CURVE CRYPTOGRAPHY, RSA AND THEIR VARIANTS-SIMULATION USING NS2S. Shivkumar, G. UmamaheswariA PKI (public key infrastructure) enables users of a basically unsecure public network to securely and privately exchange data through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. The public key infrastructure provides for a digital certificate that can identify an individual or an organization and directory services … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 18 Dec 2013 · 7,379 accessesView PDFCite

Research ArticleOpen accessIn the abstractComparative Analysis of Laboratory Measured and PVTP Software DataOluwasanmi Samuel Teniola, Mercy Isaiah OkegbemiCubic Equations of State (EOS), including the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) models, are foundational in petroleum engineering for modeling the thermodynamic behavior of hydrocarbon systems. These EOS are widely used to predict phase behavior and Pressure-Volume-Temperature (PVT) properties, which are crucial for reservoir simulation, production forecasting, and enhanced oil recovery. However, their predictive accuracy diminishes when applied to complex … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 20 Dec 2025 · 2,761 accessesView PDFCite
