A new type of spoof surface plasmon polaritons (SSPPs) developed from conventional substrate integrated waveguide (SIW) using ring slots and vias is proposed in this paper. The asymptotic frequency lower cutoff the SSPP structure can be easily tuned by changing width SIW walls radius slot, respectively. trapezoidal microstrip line a small slot are used for efficient mode conversion to smoothly ...

This paper describes our participation in SemEval-2015 Task 12, and the opinion mining system sentiue. The general idea is that systems must determine the polarity of the sentiment expressed about a certain aspect of a target entity. For slot 1, entity and attribute category detection, our system applies a supervised machine learning classifier, for each label, followed by a selection based on ...

The most important causes of bridge failure are local scour. In this study, laboratory experiments were conducted to investigate the effectiveness of slot as a protection device in reduction of depth of scour at cylindrical piers under clear water flow conditions. The development time of scour depth at the circular pier with and without a slot as a protection device was conducted. The experimen...

This paper provides experimental and implementation details for various forms of multiple-input multiple-output (MIMO) cube antennas. Slot dipole antennas are used as basic elements of these MIMO antennas. Experimental results show that especially at higher frequencies of various wireless applications the additional loss of the printed antennas increase and therefore implementation of such ante...
