Given a set A ={a1, . . . ,an} of n image points and a set B ={b1, . . . ,bn} of n model points,the problem is to find a transformation matching (a one-to-one mapping) each point a ∈ A tosome point b ∈ B such that the length of the longest edge in the matching is minimized (so-calledbottleneck distance). The geometric transformations we allow are translation, rot...

Low-grade waste heat conversion to electricity has drawn much attention toward reduction of production cost (Matsuura, Rowe et al. 1992, Rowe 1995, Ebrahimi, Jones et al. 2014). Organic Rankine cycle has been recently proved as a feasible solution with about 7% thermal efficiency and initial cost of about $2/watt for a high temperature of 116 °C and low temperature of 25 °C (Imran, Park et al. ...

Limitations of rainfall and surface water resources farmers have to use both surface and subsurface resources for growing different crops. In this study optimal management of irrigation water allocation and cropping pattern utilizing conjunctive use of surface and subsurface water resources is studied. Also the effect of reducing water consumption in different growth stages with different irrig...

in this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. the objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. we develop a warp...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
