in this paper, an efficient method for solving optimal control problemsof the linear differential systems with inequality constraint is proposed. by usingnew adjustment of hat basis functions and their operational matrices of integration,optimal control problem is reduced to an optimization problem. also, the erroranalysis of the proposed method is investigated and it is proved that the order o...

alternative legendre polynomials (alps) are used to approximate the solution of a class of nonlinear volterra-hammerstein integral equations. for this purpose, the operational matrices of integration and the product for alps are derived. then, using the collocation method, the considered problem is reduced into a set of nonlinear algebraic equations. the error analysis of the method is given an...

This paper discusses the application of plant-wide control philosophy to enhance the performance and capacity of the Produced Water Treatment (PWT) in offshore oil & gas production processes. Different from most existing facilityor material-based PWT innovation methods, the objective of this work is to propose a software-based breakthrough PWT innovation solution. This is achieved through integ...

This paper introduces how green marketing influences the sustainable development of garment industry. It analyses the cost and profit to implement green marketing, both in a short term and in the long run. In a short term the cost may increase. However, in the long run, the income will overweigh the cost. There’re five reasons: reduced cost, expanding export by broking down green barriers, esta...
