چکیده
The necessary slack and surplus/artificial variables have already been added (and hence we have all constraints in the = form). Here, A is an m× n matrix (i.e., m rows and n columns), b is an m-vector, c and x are n-vectors. Thus, the n variables (represented as x) includes the slack/surplus/artificial variables. Suppose we know which of the n variables are basic in the optimal tableau. Since there are m constraints, there will be m basic variables and (n − m) non-basic variables. Grouping all the basic

Investigation of Utilizing a Secant Stiffness Matrix for 2D Nonlinear Shape Optimization and Sensitivity Analysis
In this article the general non-symmetric parametric form of the incremental secant stiffness matrix for nonlinear analysis of solids have been investigated to present a semi analytical sensitivity analysis approach for geometric nonlinear shape optimization. To approach this aim the analytical formulas of secant stiffness matrix are presented. The models were validated and used to perform inve...
متن کاملDevelopment and Optimization of Ferrous Fumarate Chewable Tablets by Simplex Experimental Design
Chewable ferrous fumarate tablet is the best iron dosage form for children due to better compliance and lower teeth staining compared to the oral drop. Because of the different desirable properties of chewable tablets and the opposing effects of fillers on them, the mathematical experimental design was used as the formulation approach. Different series of formulations based on single filler (La...
متن کاملFloating Matrix Tablets of Domperidone Formulation and Optimization Using Simplex Lattice Design
The purpose of this research was to prepare a floating matrix tablet containing domperidone as a model drug. Polyethylene oxide (PEO) and hydroxypropyl methylcellulose (HPMC) were evaluated for matrix-forming properties. A simplex lattice design was applied to systemically optimize the drug release profile. The amounts of PEO WSR 303, HPMC K15M and sodium bicarbonate were selected as independen...
