optimization of the exploitation operation is one of the most important issues facing the mining engineers. since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. the aim of this optimization is to maximize the net present value (npv). since the objective function of this problem is non-linear, three methods can b...

The objective of this chapter is to present an optimal robust control approach based upon smart multi-objective optimization algorithms for systems with challenging dynamic equations in order to minimize the control inputs and tracking and position error. To this end, an optimal sliding and decoupled sliding mode control technique based on three multi-objective optimization algorithms, that is,...

The structural analysis of large intracontinental wrench faults is fundamental for deciphering the long-term evolution continental crust in complex areas terms their geodynamic and large-scale crustal block displacements. In this contribution, we demonstrate a pre-Miocene dextral activity present-day left-lateral Great Kavir - Doruneh Fault System (GKDFS, Central Iran), one major active strike-...

This paper puts health questions within the context of national development and industrial policy. It follows the idea of structuralist, Marxist and Schumpeterian approaches, in which industry and innovations form determining factors for the dynamism in capitalist economies and relative positions within the world economy. All countries that have developed and started to compete under better con...
