Journal Article
Robson, A., Grassie, T., & Kubie, J. (2007). Modelling of a low temperature differential Stirling Engine. Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 221, 927-943. https://doi.org/10.1243/09544062JMES631

Abstract: A full theoretical model of a low temperature difference Stirling engine is developed in this paper. The model, which starts from the first principles, gives a full differential description of the major components of the engine: the behav...

Evaluation of a new photodiode sensor for measuring global and diffuse irradiance, and sunshine duration. (2007)
Journal Article
Wood, J., Muneer, T., & Kubie, J. (2007). Evaluation of a new photodiode sensor for measuring global and diffuse irradiance, and sunshine duration. Journal of Solar Energy Engineering, 125, 1-6. https://doi.org/10.1115/1.1531149

A new integrated device (called the BF3) has been developed, which enables the simultaneous measurement of horizontal global and diffuse irradiance as well as sunshine presence at any time. The sensor needs no specific polar alignment or routine adju... Read More about Evaluation of a new photodiode sensor for measuring global and diffuse irradiance, and sunshine duration..

An investigation of possible improvements in accuracy of regressions between diffuse and global solar irradiation. (2007)
Journal Article
Clarke, P., Munawwar, S., Davidson, A., Muneer, T., & Kubie, J. (2007). An investigation of possible improvements in accuracy of regressions between diffuse and global solar irradiation. Building Service Engineering Research and Technology, 28, 189-197. https://doi.org/10.1177/0143624407076907

Horizontal hourly and sub-hourly diffuse and beam irradiance are required for the estimation of global irradiance on a given tilted surface. This information is used by engineers and architects for various solar energy applications and also to calcul...
