In this paper a particle gradient evolutionary algorithm is presented for solving complex single-objective optimization problems based on statistical mechanics theory, the principle of gradient descending, and the law of evolving chance ascending of particles. Numerical experiments show that we can easily solve complex single-objective optimiz ation problems that are difficult to solve by using...

The Newton-type regularization CG-REGINN is an efficient tool for stably solving nonlinear ill-posed problems. In this paper a new convergence analysis for a slightly modified version of CG-REGINN is given, extending previous results by Hanke [Numer. Funct. Anal. Optimiz. 18, 971-993, 1997] and the second author [SIAM Numer. Anal. 43, 604-622, 2005]. Some numerical experiments from electrical i...

Vie present a method of transforming an extract-based DNA computation that is error-prone into one that is relatively error-free. These improvements in error rates are achieved without the supposition of any improvements in the reliability of t he underlying laboratory techniques. Vle assume that only two types of errors are possible: a DNA strand may be incorrectly processed or it may be lost ...

in thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. in this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. the model is used to predict the steady state profiles of the gas temperature and product yields. using a dy...

A detailed model was developed for the emulsion copolymerization of styrene and MMA to predict the evolution of the particle size distribution (PSD) and molecular weight distribution (MWD) over the entire range of monomer conversion. A system exhibiting zero-one kinetics was employed. The model was used to optimise the emulsion copolymerization process in order to maximize particle size polydis...

Chemical engineering deals with synthesis of various chemicals in economical and efficient manner. Raw material is important aspect for cost effective manufacturing of chemicals. Biological methods for syntheis consume less energy and are very economical for production of chemicals such as ethanol, acetic acid, citric acid, lactic acid etc. Waste solid materials such as molassis, fruit peels, w...

Soursop is a typical fruit with high nutritonal value. Its perishability of soursop and the short shelf life after harvesting are main difficulties in enhancing its potential market for fresh consumption. The (Annona muricata) usually transformed into juice, pulp concentrate. In order to accelerate valuable characteristics, present investigation wascarried out optimiz different parameters proce...
