Orbital Angular Momentum (OAM) may be a candidate for future communication systems due to its advantages in terms of high data rates and effective frequency utilization. OAM can provide a solution where a beam is transformed ...

In this paper a novel orthogonal frequency division multiplexing (OFDM) scheme called OFDM with index modulation (OFDM-IM) is proposed for operation over frequency-selective and rapidly time-varying fading channels. In ...

In this article we introduce the concept of (p alpha)-switching trees and use it to provide sufficient conditions on the abelian groups G and H for when CAY (G x H

Do voters reward incumbents for the provision of public services? In this article, we study the political economy of catchment areas of public services to answer this question. Rather than examining the binary relationship ...

In this paper we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve ...

After experiencing a period of spectacular growth during the late nineteenth century, the Egyptian cotton sector underwent a phase of stagnation, which was followed by a gradual and steady increase in output during the ...

I look at the relationship between corporate loan terms and board members' connections to bankers through employment on other boards, a connection relatively unaffected by confounding factors. Using syndicated loan data, ...

This study examines the oxygen diffusion into polystyrene (PS) latex/multiwalled carbon nanotube (MWNT) nanocomposite films (PS/MWNT) consisting of various amounts of MWNT via steady state fluorescence technique (SSF). ...

A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films. The composite films were prepared from the mixture of surfactant-free pyrene ...
