A bandpass negative group delay (NGD) passive circuit based on defect ground structure (DGS) and substrate integrated waveguide (SIW)-matched is developed in the paper. The NGD DGS topology originally built with notched cells associated self-matched elements. design method introduced as a function of geometrical SIW via Then, parametric analyses full wave 3-D electromagnetic <tex xmlns:mml="htt...

The unified property specifies that a comparison-based search structure can quickly find an element nearby a recently accessed element. Iacono [Iac01] introduced this property and developed a static search structure that achieves the bound. We present a dynamic search structure that achieves the unified property and that is simpler than Iacono’s structure. Among all comparison-based dynamic sea...

Systems Architecture is a generic discipline to handle objects (existing or to be created) called systems, in a way that supports reasoning about the structural properties of these objects. Systems Architecture is a response to the conceptual and practical difficulties of the description and the design of complex systems. Systems Architecture is a generic discipline to handle objects (existin...

In this paper, we extend the sliding mode idea to a class of unmatched uncertain variable structure systems. This method is achieved with introducing a new terminal sliding variable and the finite time stability of proposed method is proved using a new particular finite time condition in both reaching and sliding phases. In reaching phase new sliding mode controller is derived to guarantee the ...
