The optimal solution of a geometric program (GP) can be sensitive to variations in the problem data. Robust geometric programming can systematically alleviate the sensitivity problem by explicitly incorporating a model of data uncertainty in a GP and optimizing for the worst-case scenario under this model. However, it is not known whether a general robust GP can be reformulated as a tractable o...

The human placenta is one of the most complex organs with multi-functions, i. e. transportation of water and metabolites between the maternal and fetal circulation, production of estrogen, progesterone and gonadotropins. The recent application of the investigative methods, tissue culture or electron microscopy other than light microscopy, to the human placenta has thrown more light on the funct...

Abstract We use methods from nonstandard analysis to unify and extend results the theory of asymptotic fixed points on metric spaces. Among topics we consider are Kirk’s point theorem with extensions, Boyd Wong’s theorem, Suzuki’s for contractions Meier–Keeler type. also show how final type can be modified yield uniform convergence compact bounded sets.

In this paper the behaviour of discrete-time linear systems is investigated. A complete characterization of all discrete-time linear systems of convolution type is given in the paper. The result is a generalization of results given by S. Boyd and I. Sandberg.

Considering the ω-distance function defined by Kostić in proximity space, we prove Matkowski and Boyd–Wong fixed-point theorems space using ω-distance, provide some examples to explain novelty of our work. Moreover, characterize Edelstein-type theorem compact space. Finally, investigate an existence uniqueness result for solution a kind second-order boundary value problem via obtained Matkowski...
