Super steel materials play a vital role in the construction and fabrication of structural, piping and pipeline components. In assuring the integrity of onshore and offshore operating systems, they enable life cycle costs to be minimized. In this context, Duplex stainless steel (DSS) material related welding on constructions and fabrications plays a significant role in maintaining and assuring i...

−− Time optimal monomer and reactor temperature set-point profiles were computed and implemented experimentally for the control of copolymer composition and minimization of reaction time in emulsion copolymerization systems. Iterative Dynamic Programming (IDP) was used for the offline calculation of the optimal profiles. This approach can deal with constrained optimization of systems described ...

This paper points out that there exists a unique optimal approximation of autocorrelation function of an asymptotically second-order selfsimilar process. A simple type of autocorrelation functions is used to explain the method of optimal solution and verify the long-range dependence of traffic in the view of optimal approximation. KeywordsModeling, long-range dependence

the production of public goods like amenity value of the landscape, food security, preservation of rural communities and rural lifestyle, by agricultural sector is a subject that has been widely accepted by experts. however, in many policies and political analyses carried out, solely the production of private goods by the agricultural sector is paid attention and the important function of publi...

In this article, it is considered a class of optimal control problems constrained by differential and integral constraints are called canonical form. A modified measure theoretical approach is introduced to solve this class of optimal control problems. Keywords—Optimal control problem, Canonical form, Measure theory.

this paper investigates an epq model with the increasing demand and demand dependent production rate involving the trade credit financing policy, which is seldom reported in the literatures. the model considers the manufacturer was offered by the supplier a delayed payment time. it is assumed that the demand is a linear increasing function of the time and the production rate is proportional to ...
