In this paper, two microstrip-fed printed slot antennas have been introduced to be used in modern communication systems, as alternatives for conventional Hilbert slot antenna. The slot structures of the proposed antennas are in the form of the 3rd iteration of two variants of the conventional Hilbert space-filling curves. These antennas are fed with 50 Ω microstrip line printed on the reverse s...

The subject of this paper is the analysis of a discrete-time queueing model with infinite capacity, a single server serving exactly one packet per slot and with N input lines. On each of these input lines, there are messages arriving to the system that consist of exactly m packets. The important feature of this model however, is the fact that the packets of a message do not all enter the system...

Following the footsteps of SemEval-2014 Task 4 (Pontiki et al., 2014), SemEval-2015 too had a task dedicated to aspect-level sentiment analysis (Pontiki et al., 2015), which saw participation from over 25 teams. In Aspectbased Sentiment Analysis, the aim is to identify the aspects of entities and the sentiment expressed for each aspect. In this paper, we present a detailed description of our sy...

In this paper, a novel W-band substrate integrated waveguide (SIW) power combiner/divider is analyzed theoretically and demonstrated experimentally/numerically, based on the antipodal fin-line SIW-rectangular waveguide (SIW-RW) transition and longitudinal slot coupling techniques. This antipodal fin-line SIW-RW transition can work at the frequency band of 86.4GHz– 106.1GHz with return loss larg...

This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are s...
