Exchange Rate and Inflation Dynamics in a Resource Rich Setting: The Case of Zambia (2019)
Journal Article
Roger, L., Smith, G., & Morrissey, O. (2019). Exchange Rate and Inflation Dynamics in a Resource Rich Setting: The Case of Zambia. South African Journal of Economics, 87(4), 490-514. https://doi.org/10.1111/saje.12236

This paper investigates the relationship between copper prices, the exchange rate and consumer price inflation in Zambia using a structural vector autoregression with quarterly data for 1995–2014 and a combination of sign and zero restrictions to ide...

Experimental setup of continuous ultrasonic monitoring for corrosion assessment (2017)
Conference Proceeding
Suchato, N., Kalashnikov, A., Light, R., & Sharples, S. (in press). Experimental setup of continuous ultrasonic monitoring for corrosion assessment.

The paper is devoted to the ultrasonic monitoring of accelerated corrosion. In order to achieve non-uniform corrosion (high surface roughness), passivation was applied to the corroding surface. A dedicated electronic multiplexed four channel front en... Read More about Experimental setup of continuous ultrasonic monitoring for corrosion assessment.

Experimental evaluation of ultrasonic oscillating temperature sensors (UOTS) under cyclically changing temperatures (2015)
Conference Proceeding
Hashmi, A., Kalashnikov, A. N., & Light, R. A. (2015). Experimental evaluation of ultrasonic oscillating temperature sensors (UOTS) under cyclically changing temperatures.

In contrast to most conventional temperature sensors, which need to come to thermal equilibrium with the medium of interest to report its temperature, UOTS interrogate the medium based on the propagation speed of ultrasound, and will return temperatu...

Widefield two laser interferometry (2014)
Journal Article
Patel, R., Achamfuo-Yeboah, S., Light, R. A., & Clark, M. (2014). Widefield two laser interferometry. Optics Express, 22(22), https://doi.org/10.1364/OE.22.027094

A novel system has been developed that can capture the wide- field interference pattern generated by interfering two independent and incoherent laser sources. The interferograms are captured using a custom CMOS modulated light camera (MLC) which is c... Read More about Widefield two laser interferometry.

A Weber-like law for perceptual learning (2013)
Journal Article
Astle, A. T., Li, R. W., Webb, B. S., Levi, D. M., & McGraw, P. V. (2013). A Weber-like law for perceptual learning. Scientific Reports, 3, Article 1158. https://doi.org/10.1038/srep01158

What determines how much an organism can learn? One possibility is that the neural factors that limit sensory performance prior to learning, place an upper limit on the amount of learning that can take place. We tested this idea by comparing learning... Read More about A Weber-like law for perceptual learning.

Ultrastable heterodyne interferometer system using a CMOS modulated light camera (2012)
Journal Article
Patel, R., Achamfuo-Yeboah, S., Light, R., & Clark, M. (2012). Ultrastable heterodyne interferometer system using a CMOS modulated light camera. Optics Express, 20(16), https://doi.org/10.1364/OE.20.017722

A novel ultrastable widefield interferometer is presented. This uses a modulated light camera (MLC) to capture and stabilise the interferogram in the widefield heterodyne interferometer. This system eliminates the contribution of piston phase to the... Read More about Ultrastable heterodyne interferometer system using a CMOS modulated light camera.

Widefield heterodyne interferometry using a custom CMOS modulated light camera (2011)
Journal Article
Patel, R., Achamfuo-Yeboah, S., Light, R., & Clark, M. (2011). Widefield heterodyne interferometry using a custom CMOS modulated light camera. Optics Express, 19(24), https://doi.org/10.1364/OE.19.024546

In this paper a method of taking widefield heterodyne inter- ferograms using a prototype modulated light camera is described. This custom CMOS modulated light camera (MLC) uses analogue quadrature demodulation at each pixel to output the phase and am...
