Journal Computers and Industrial Engineering, 2004 [citation][year=2015]An automated method for tree-ring delineation based on active contours guided by DT-CWT complex coefficients in photographic images: Application to Abies alba … P Kennel, P Borianne, G Subsol - Computers and Electronics in Agriculture, 2015 - Elsevier Abstract This paper describes an efficient method for delineating tree-rings and inter tree- rings in wood slice images. The method is based on an active contour approach and a multi- scale gradient map resulting from the Dual Tree Complex Wavelet Transform (DT-CWT). ... [citation][year=2014]Combining grey relation analysis and entropy model for evaluating the operational performance: an empirical study CC Sun - Quality & Quantity, 2014 - Springer Abstract Decision-making on operational performance evaluation is a complex multi- objective problem. Through the combination of grey relation analysis and information entropy, the evaluation results are more objective and reasonable. This paper would ...

Standing on virtualization techniques, low maintenance costs and economies of scale, cloud computing emerged in the last few years as a major trend in the industry. Since cloud resources grow and shrink as needed, providers and users of the cloud must ... 2000(4 publications) [publication]Vaz, C. and P.
