This paper presents the technical performance results of a measurement campaign from 5G indoor millimeter Wave (mmWave) and Visible Light Communications (VLC) multi component carrier system, which was developed in Horizon 2020 research project called Internet Radio-Light (IoRL). The performed famous Integer House laboratory at Innovation Park Building Research Establishment Watford, U.K., repre...

Multi-phase (more than three-phase) converters are required mainly for feeding variable speed multi-phase drive systems. This paper discusses one such solution by using direct ac-ac converter that can be used to supply a five-phase two-motor drive system. Matrix converter based two-motor drive system is presented for the first time in this paper. Two stator windings of two five-phase machines w...

In this paper a multi-agent system architecture for a modular mobility enhancement system is presented. The system consists of one or multiple mobile robotic platforms and a set of user defined application modules, such as chairs, tables multifunctional chairs etc. All these modules can be inexpensive everyday life items, that become functional when a mobile platform is properly attached to the...

Multi-carrier energy systems have received wide attentions due their flexibility and sustainable characteristics. Although these show significant efficiency in providing consuming energy, the performance of whole system can be degraded owing to uncertainties arising from different sources. This paper presents a stochastic decentralized model for considering including types thermal electrical pr...

this paper presents a new strategy based on multi-stage fuzzy (msf) pid controller based on artificial bee colony (abc) for damping power system stabilizer (pss) in multi-machine environment. the recent studies in artificial intelligence demonstrated that the abc optimization is strong intelligent method in complicated stability problems. also, finding the parameters of pid controller in power ...

In this paper, we study the sensitivity of uplink and downlink MC-DS-CDMA to carrier frequency offsets, assuming orthogonal spreading sequences. For both uplink and downlink MC-DS-CDMA, we show that the performance rapidly degrades for an increasing ratio of maximum frequency offset to carrier spacing. We point out that the degradation in the uplink is larger than in the downlink, because only ...
