Research ArticleOpen accessIn the abstractFinding the Envelope and Efficient Frontier of Financial AssetsFarida Kachapova, Ilias KachapovProblem statement: One of the problems considered in financial mathematics is finding portfolios of given financial assets that minimize risk for targeted returns. The set of such portfolios is called the envelope of the assets. Traditionally this problem is solved as a calculus minimization problem involving partial derivatives and Lagrange multipliers. Approach: In this study we describe an invariant geometric … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 16 Jul 2012 · 9,279 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVariational Homotopy Perturbation Method for the Zakharove-Kuznetsov EquationsMashaallah Matinfar, Maryam GhasemiProblem statement: In this research, the Variational Homotopy Perturbation Method (VHPM) which is a combination of Variational Iteration Method (VIM) and Homotopy Perturbation Method (HPM) used for the Zakharove-Kuznetsov equations (ZK-equations). Approach: These two methods are proposed by chinese researcher J.H.He. M.A.Noor improved these two methods and established the VHPM. The numerical solution of ZK-equation is of great importance dut … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 24 Dec 2010 · 7,254 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFPGA Implementation of Power Aware FIR Filter Using Reduced Transition Pipelined Variable Precision GatingA. Senthilkumar, A. M. NatarajanWith the emergence of portable computing and communication system, power awareness is one of the major objectives of VLSI Design. This is its ability to scale power consumption based on the time-varying nature of inputs. Even though the system is not designed for being power aware, systems display variations in power consumption as conditions change. This implies, by the definition … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,315 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Analysis of the Output and Employment Conversion Matrices of Australia's EconomyAbbas Valadkhani, Tim RobinsonBased on two snapshots taken from the Australian economy, this study quantifies the impacts of final demand aggregates on output and employment in various sectors using the 1989 and 1997 conversion matrices. The sectoral output and employment are linked with final demand deliveries in such a way that one can measure the impacts on changes in each component of aggregate … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,750 accessesView PDF Cite
