Optimization of sustained release delivery Olanzapine system

Optimization of sustained release delivery Olanzapine system

The objective of this study is to develop controlled release formulation of water insoluble Olanzapine (OZ), using Glycerol monooleate (GMO) and Polyethylene glycol (PEG 300). A Box-Benkhen response surface methodology was applied to design gel system with 3 factors with an initial drug containing within the range of 2-4%, weight ratio of GMO/water (w/w) in the range of 2-4% and weight ratio of PEG 300/GMO (w/w) in the range of 2-6%. Dependent variables include entrapment efficacy (EE %), ...

Convergence Rate of GMRES on Tridiagonal Toeplitz Linear System

Convergence Rate of GMRES on Tridiagonal Toeplitz Linear System

This paper aimed to review paper [10] titled ldquo;The rate of convergence of GMRES on a tridiagonal toeplitz linearsystem II rdquo; by Ren-cang Li amp; Wei Zhang and its references, in which linear system Ax=b is solved using Toeplitzmatrices by generalized minimal residual method. Based on this thesis, this method is the best and most completeway to solve asymmetric matrices. Since the analysis of the convergence of such systems is difficult and complex,2nd order orthogonal Chebyshev ...

SYSTEM IDENTIFICATION USING MICROCONTROLLER-BASED N-PRBS GENERATOR

SYSTEM IDENTIFICATION USING MICROCONTROLLER-BASED N-PRBS GENERATOR

System identification is dealing with dedicated experimental data to find a compact and accurate mathematical model of a dynamic system. The main goal of this paper is to present the system identification technique to yield a good transfer function of the actual plant. The steps start with hardware setup, data collection, model estimation, and eventually model validation. Based on input and output data of the system, best fit criterion, and correlation analysis of the residual is utilized to ...

Fuzzy Sliding-Mode Controller Design for Two 4-D Different Hyperchaotic System

Fuzzy Sliding-Mode Controller Design for Two 4-D Different Hyperchaotic System

This paper presents a fuzzy sliding mode controller for synchronization of two 4-D hyperchaotic systems. This paper describes two 4-D hyperchaotic systems a LU system and a Newton-Leipnik system. A LU system is defined as master system and the Newton-Leipnik system is defined as the slave system. In the controller design, an additional controller is designed using a sliding surface to ensure the sliding motion through the entire state trajectory. The method of designing a fuzzy sliding mode ...

Transient Stability Margin Assessment of a Power System Using Multi-Layered Perceptron Neural Network

Transient Stability Margin Assessment of a Power System Using Multi-Layered Perceptron Neural Network

Online transient stability assessment of a power system is not yetfeasible due to the intensive computation involved. Artificial neuralnetworks have been proposed as one of the approaches to this problembecause of its ability to quickly map nonlinear relationships between theinput data and the output. This paper presents a methodology forestimating the normalized transient stability margin by using themultilayered perceptron neural network. The complex relationshipbetween the input variables ...
