PETER, J., PRABHU, R., RADHAKRISHNAN, P., VALLABHAN, C.P.G., NAMPOORI, V.P.N. and KAILASNATH, M. 2015. Angular dependent light emission from planar waveguides. Journal of applied physics, 117(1), Article 015301. Available from: https://doi.org/10.1063/1.4905011

We have investigated the angular dependence of amplified spontaneous emission (ASE) and laser emission from an asymmetric and free-standing polymer thin films doped with rhodamine 6G, which is transversely pumped by a pulsed Nd:YAG laser. A semi-leak... Read More about Angular dependent light emission from planar waveguides..

Suppressing stick-slip oscillations in underactuated multibody drill-strings with parametric uncertainties using sliding-mode control. (2015)
Journal Article
LIU, Y. 2015. Suppressing stick-slip oscillations in underactuated multibody drill-strings with parametric uncertainties using sliding-mode control. IET control theory and applications [online], 9(1), pages 91-102. Available from: https://doi.org/10.1049/iet-cta.2014.0329

Stabilisation of multibody drill-strings which exhibit stick-slip oscillations is studied in this paper from the point of view of underactuated system. The model has one control torque input acting on the rotary table from the land surface and multi-...
