The power law process has been used extensively in software reliability models, reliability growth models and more generally reliable systems. In this paper we work on the Power Law Process via empirical Bayes (EB) approach. Based on a two-hyperparameter natural conjugate prior and a more generalized three-hyperparameter natural conjugate prior, which was stated in Huang and Bier (1998), we wor...

The main impairment of an orthogonal frequency division multiplexing (OFDM) systems is an intercarrier interference (ICI) effect caused by a frequency offset. A zero-padded technique designed for a conjugate cancellation scheme in MIMO-OFDM systems for ICI cancellation is proposed by padding zero between two consecutive symbols over a space-frequency domain. At the receiver, the ICI cancellatio...

It is established that there exists an intimate connection between isometric deformations of polyhedral surfaces and discrete integrable systems. In particular, Sauer’s kinematic approach is adopted to show that second-order infinitesimal isometric deformations of discrete surfaces composed of planar quadrilaterals (discrete conjugate nets) are determined by the solutions of an integrable discr...

The solution of large sparse systems of linear equations is one of the most computationally intensive parts of nite element simulations. In order to solve these systems of linear equations, we have implemented a parallel conjugate gradient solver on the SPMD-programmable MUSIC-system. We outline the conjugate gradient method, give a formal speci cation in Maple, and describe a data-parallel pro...

1. Introduction. We consider the resolution of large-scale nonlinear problems arising from the finite-element discretization of geometrically non-linear structural analysis problems. We use a classical Newton Raphson algorithm to handle the non-linearity which leads to the resolution of a sequence of linear systems with non-invariant matrices and right hand sides. The linear systems are solved ...

aflatoxins are a group of fungal toxic metabolites, which are contaminated certain food commodities. elisa is one of the sensitive methods for detection of aflatoxins. preparation and stabilizing of a proper conjugated tracer for detection of aflatoxins is probably the main step for designing an elisa method. in current study, different stabilizers were applied to stabilize a newly prepared con...

We focus on the minimal time control problem for single-input control-affine systems ẋ = X(x) + u1Y1(x) in IR with fixed initial and final time conditions x(0) = x̂0, x(t f ) = x̂1, and where the scalar control u1 satisfies the constraint |u1(·)| 6 1. For these systems a concept of conjugate time tc has been defined in e.g. [3, 30, 33] in the bang-bang case. Besides, theoretical and practical iss...

Since its introduction by August Kekulé in 1865,1 the concept of aromaticity has been continuously conquering new territories in chemistry (refs 2-20 are only a small fraction of the published articles, reviews, books, and conference proceedings on this subject). Initially, aromaticity was developed for the following classes of organic compounds: (i) monocyclic planar conjugate hydrocarbons and...

abstract many studies have been conducted on the characteristics of hydraulic jump over gradually expanding cross sections, but comparatively few have been carried out on basins with convergent wall. in the present research, the hydraulic jump characteristic of the stilling basin with convergent wall has been investigated. the main objective of this research is evaluation of conjugate depths ra...

Many scientific applications require one to solve successively linear systems Ax = b with different right-hand sides b and a symmetric positive definite matrix A. The conjugate gradient method applied to the first system generates a Krylov subspace which can be efficiently recycled thanks to orthogonal projections in subsequent systems. A modified conjugate gradient method is then applied with ...
