Research ArticleOpen accessIn the abstractA New Architecture for Improving Location Management in PCS NetworksHaidar Safa, Samuel PierreThis study proposes a new architecture for improving the location management in PCS networks. The proposed architecture employs several HLRs as opposed to one HLR in the IS-41 and GSM models. Indeed, the new architecture associates with each MU two types of HLRs ; a resident HLR that serves the location areas in which the MU often resides and a … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,783 accessesView PDFCite

The numerical work includes the establishing of a multi-branch reaction code to be used for simultaneous fusion reactions of D-D, D-T D-He3 and mutual nuclear reaction products. This will permit the studies of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving Linear Programming Problems on the Parallel Virtual Machine EnvironmentJrJung Lyu, Hsing Luh, Ming-Chang LeeThis study developed a parallel algorithm to efficiently solve linear programming models. The proposed algorithm utilizes the Dantzig-Wolfe Decomposition Principle and can be easily implemented in a general distributed computing environment. The analytical performance of the well-known method, including the speedup upper bound and lower bound limits, was derived. Numerical experiments are also provided in order to verify the complexity … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,841 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Study on the Influence of Fault on the Seepage and Stress Field of FormationYongxiang Zheng, Jianjun Liu, Bohu Zhang, Yue SunIn the process of water injection in oil field, the fault will affect the seepage field and stress field of the formation, which leads to the deformation and destruction of the formation. Therefore, more casing damage wells are found around the fault. In order to study the influence of fault on the formation in the process of water injection, a … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 9 Feb 2017 · 7,352 accessesView PDFCite

A weak convergence of a three - step iterative scheme involving the resolvents of accretive operators is proved. The main result is applied to a convex minimization problem in Hilbert spaces. In particular, the minimizer of a convex and proper lower semi-continuous function defined … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 31 Jul 2020 · 6,467 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTime-Temperature Dependency of Laminated Glass Subjected to Blast Load – A Numerical StudyMatthias FörchThe behavior of laminated glass has strong time-temperature dependency. Viscoelastic material models are often employed to define mechanical properties of Polyvinyl Butyral (PVB), the most common interlayer for structural glass applications. However, it is an apparent notion to simplify the high complexity of such material models, as only specific software is capable of considering this behavior. Most studies in blast … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 18 Mar 2020 · 7,682 accessesView PDFCite
