—Spectrum awareness is an essential part of Cognitive Radio (CR) systems that enables CR systems to intelligently utilise the spectrum. Accurate modeling of spectrum utilization is crucial for the development and performance evaluation of such systems. In this paper, a wideband spectrum occupancy measurement campaign is conducted to study the utilization of(More)
A water-based solution of polyvinylpyrrolidone (PVP) at various concentrations and zinc nitrates were used in conjunction with calcination to produce zinc oxide semiconductor nanoparticles. The extent to which the zinc oxide semiconductor nanoparticles had become crystallized was measured using X-ray diffraction (XRD), whilst morphological characteristics(More)
This paper presents a wireless, low power and low cost wearable for real time monitoring and analysis of bowling action in the game of cricket. Utilizing flex sensor as an enabling component, the device performs continuous measurement of arm angle within one degree accuracy. The wearable also utilizes a force sensor enabling it to detect the time instant at(More)
In recent years, much research emerged to modify Stone's BSS method for solving a blind source separation problem; Stone's method used to recover original signals from the mixture. In this work, new direction has been opened to use an intelligent soft computing technique (Fast Genetic Algorithm) with the temporal predictability of signals based on Stone's(More)
