This paper proposes a lefthanded circularly polarized (LHCP) 2×4 array antenna using sequential phase rotation power dividers at 5.8 GHz band. The element antenna is a square patch antenna with a slit in the middle for better impedance matching, six trapezoidal parasitic patches added to either side of the main patch to create resonance at high frequencies, and a metasurface placed on top of the main patch.

A Knowledge-based Decision Support System (KB-DSS) based on a multi-stage Fuzzy Logic Controller (MS-FLC) is developed for traffic congestion management on expressways. In a case study, the KB-DSS is evaluated on a simulated network in comparison to ALINEA\Q, a popular ramp control method, across various traffic and incident situations.

Social media are currently building their own empire and power since they have great influence in a flat world. They play an important role in the communication of human beings i.e. sharing information and connecting people. Social media have become the main sources of getting latest news and platforms to spread ideas and mindsets. It is therefore essential to know and understand social media’s key vocabulary and terminologies. The paper analyses and synthesizes 100 collected words concerning social media.

This study examined the current situation of the Serbian Orthodox Church both in its Australian and transnational contexts since the Serbian Orthodox Church functions as transnational network with churches linked globally. The research strategy was a combination of qualitative and quantitative methods. This included a case study approach which focused in four parishes in Australia, including interviews which involved forty six participants affiliated to Serbian Orthodoxy and four Serbian Orthodox priests who were individually interviewed.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.
