Given the reduced freshwater supplies across the world, seawater desalination is one of the appropriate methods available for producing freshwater. Selecting an optimal location is crucial in the installation of these plants owing to the environmental problems they cause. The present study was conducted to identify optimal locations for installing desalination Plants in the coastal areas of sou...

We consider the problem of simultaneous approximation real numbers $\theta_1, …,\theta_n$ by rationals and dual approximating zero values linear form $x_0+\theta_1x_1+…+\theta_nx_n$ at integer points. In this setting we analyse two transference inequalities obtained Schmidt Summerer. present a rather simple geometric observation which proves their result. also derive several previously unknown ...
