Knowledge-based information systems : a wind farm case study

Autor: Chen, Bindi, Song, W.W., Qiu, Y.N., Feng, Y., Tavner, P.J.

Publikováno v: Pooley, R. & Coady, J. & Linger, H. & Barry, C. & Lang, M. & Schneider, C. (Eds.). (2013). Information systems development. : Springer, pp. 539-550

The process of Information Systems Development (ISD) has been widely studied in order to enhance information systems so generated. Recently, it has been recognised that using the methodologies of knowledge management in ISD, so called knowledge-based

Bayesian network for wind turbine fault diagnosis

Autor: Chen, Bindi, Tavner, P.J., Feng, Y., Song, W.W., Qiu, Y.N.

Publikováno v: EWEA 2012, Copenhagen, Denmark, 16-19 April 2012 [Conference proceedings]

Wind turbine reliability studies have become more important because good wind turbine reliability with predictable turbine maintenance schedule will reduce the cost of energy and determine the success of a wind farm project. Previous research on wind

Ion irradiation induced nitrogen mobility in a GaInNAs quantum well laser

Autor: Qiu, Y.N. Papaioannou, G. Pozo, J. Rorison, J.M. Saarinen, M. Konttinen, J. Viheriälä, J. Leinonen, P. Jouhti, T. Pessa, M.

Changes in the optical properties in GaInNAs/GaAs quantum wells after alpha particle bombardment followed by low temperature annealing are reported. Both blue and red shifts of the lasing wavelength are observed under different annealing conditions.

N-N pair effects on GaInNAs semiconductor optical amplifiers

Autor: Alexandropoulos, D. Vogiatzis, N. Qiu, Y.N. Pozo, J. Syvridis, D. Rorison, J.M.

We explore the effects of N-N pairs on the amplifying properties of GaInNAs based Semiconductor Optical Amplifiers. The bandstructure of GaInNAs is calculated with the 3 band anti-crossing model to account for the N-N pairs for the conduction band an
