Iterated contraction mappings and fixed point theorems in metric spaces
, 1972 The main object of this thesis is to study fixed point theorems for iterated contraction mappings in metric and generalized metric spaces. -- In the beginning, we have discussed Banach’s Contraction Principle, "A contraction mapping of a complete ...

Microwave device modeling exploiting generalized space mapping [PDF]
, 2000 We present a comprehensive framework to engineering device modeling which we call Generalized Space Mapping (GSM). GSM significantly enhances the accuracy of available empirical models of microwave devices by utilizing a few relevant full-wave EM ...
