In this paper, the research advances in SIW-like (Substrate Integrated Waveguide-like) guided wave structures and their applications in the State Key Laboratory of Millimeter Waves of China is reviewed. Our work is concerned with the investigations on the propagation characteristics of SIW, half-mode SIW (HMSIW) and the folded HMSIW (FHMSIW) as well as their applications in microwave and millim...

The search in P2P systems is still a problem because of the dynamic nature of these systems and the lack of central catalogs. In order to improve the search in P2P systems, a sorted structure is created from the content of all nodes in the system. Different from other approaches, a tree like structure is built by tokens which are constantly moving between the nodes and carrying all structural i...

The dichotomic physical quantities, also called propositions, can be naturally associated to maps of the set of states into the real interval [0,1]. We show that the structure of effect algebra associated to such maps can be represented by quasiring structures, which are a generalization of Boolean rings, in such a way that the ring operation of addition can be non-associative and the ring mult...
