RISComparing Liner and Non-Liner Relationships between Accounting Variables and Dividend: Evidence of Iranian Chemical Industries
The aim of this study is to compare the linear and non-linear relationships between accounting
variables and dividend of industrial chemical companies listed on the Tehran Stock Exchange from
2005 to 2010. Regression...
Combining Exact and Heuristic Approaches for the Covering Salesman Problem
and heuristic approach which takes advantage of Integer Linear Programming (ILP) techniques and heuristic search to improve the quality of the solutions. Extensive computational tests on the standard benchmark instances and on a new set of large sized...
Prediction and Statistical Control of a Piecewise Linear Profile
This research is performed in order to forecast the parameters of a piecewise linear profile to be able to investigate its control status. It introduces a new phase, called phase III, further to former phases: construction (Phase I) and monitoring...
On an optimal shape design problem to control a thermoelastic deformation under a prescribed thermal treatment
Abstract A shape optimization problem concerned with thermal deformation of elastic bodies is considered. In this article, measure theory approach in function space is derived, resulting in an effective algorithm for the ...
Statistical inference in the partial linear models with the double smoothing local linear regression method
Solutions of fuzzy LR algebraic linear systems using linear programs
Using linear programs, we give the necessary and sufficient conditions for the solvability of a fuzzy LR algebraic linear system. Fuzzy LR algebraic linear systems are linear systems with LR fuzzy coefficient matrix and an LR fuzzy vector...
A NEW APPROACH FOR SOLVING OF LINEAR TIME VARYING CONTROL SYSTEMS
This paper is concerned with the solution of Linear Time Varying
[LTV] control systems. The concept of a solution for LTV systems is defined
on the basis of finding the fundamental matrix corresponding to LTV control...
Linear and Non-linear Analyses of Functionally Graded Plates Using Generalized Differential Quadrature Method
Linear and non-linear static analyses of moderately thick functionally graded (FG) rectangular plates with different boundary conditions are presented using generalized differential quadrature (GDQ) method. The modulus of elasticity of the plates...
A new approach for solving of nonlinear time varying control systems
This paper is concerned with the solution of linear time varying control systems. The concept of a solution .......
New approach for attenuation correction in SPECT images, using linear optimization
approaches. As the correction equation in mathematical approaches is nonlinear, in this study a new method of linearization called ‘Piece Wise Linearization’ (PWL) is introduced and to substantiate its validity for SPECT image reconstructions, a phantom study...
