A significant proportion of classes in modern software introduce or use object protocols, prescriptions on the temporal orderings method calls objects. This article studies search-based test generation techniques that aim to exploit a particular abstraction protocols (enabledness preserving abstractions (EPAs)) find failures. We define coverage criteria over an extension EPAs includes abnormal ...

The principle object of this paper is to offer a modified design of Rogowski coil based on its frequency response. The improvement of the integrator circuit for nullifying the phase difference between the waveforms of the measured-current and the corresponding terminal voltage is a further object of this investigation. This paper addresses an accurate, yet more efficient measuring and protect...
