Open Access research that is helping to improve educational outcomes for children

Strathprints makes available scholarly Open Access content by researchers in the School of Education, including those researching educational and social practices in curricular subjects. Research in this area seeks to understand the complex influences that increase curricula capacity and engagement by studying how curriculum practices relate to cultural, intellectual and social practices in and out of schools and nurseries.

Research at the School of Education also spans a number of other areas, including inclusive pedagogy, philosophy of education, health and wellbeing within health-related aspects of education (e.g. physical education and sport pedagogy, autism and technology, counselling education, and pedagogies for mental and emotional health), languages education, and other areas.

Abstract

This paper investigates the possible benefits of using a Purina fractal array for beamforming, since this particular fractal has recently been suggested as the flight formation for a fractionated space craft. We analyse the beam pattern created by this, and define power concentration as measure of focussing the main beam of a multi-dimensional array. Using this performance metric and the computation cost of the array, a comparison to full lattice arrays is made. We quantify the significant benefits of the Purina array offered over a full lattice array of same complexity particularly at lower frequencies, and the complexity advantages over full lattice arrays of same aperture, particularly if energy is to be concentrated within a small angular spread.
