The uncertainty in the availability of wind generation and the lack of coincidence between wind generation and system peak demand make wind farms (WFs) to be nondispatchable energy resources and impose limits on the potential penetration of wind generation in the generation mix. Battery energy storage systems (BESSs) integrated with WFs can reduce the variability […]

A folded, cavity-backed crossed-slot antenna is proposed for antenna miniaturization. The cavity dimensions of a conventional cavity-backed crossed-slot antenna are about a half-guided-wavelength along each side, which is unsuitable in many applications like a handheld device or body area network(BAN). To reduce the size of the cavity, a folded cavity is proposed in this letter. The […]

We experimentally demonstrate an optical-wireless transmission system at W band, which can support long-distance wireless transmission and tolerate some frequency difference of the local oscillators (LOs) at the receiver. The generation of millimeter-wave signal is based on the photonic technique by heterodyne mixing of an optical polarization division multiplexing quadrature phase shift keying (PDM-QPSK) signal […]

Information technology changes and gives shape to networked society all over the world today and its solutions are becoming main drivers in almost all fields of human life activity. One of those solutions is the empowerment of e-government technologies through mobile solutions. Although the acceptance rate of e-government applications is increasing, e-voting is hardly accepted as main […]
