ii ACKNOWLEDGEMENTS If I have seen this far, it is because I have stood on the shoulders of giants.-Sir Isaac Newton I am highly indebted to my advisor, Dr. Sunanda Mitra for providing consistent support and guidance both technically and financially during my Master's program. Her timely suggestions and valuable advice enabled the successful completion of this work. I would also like to thank D...

breast cancer is the second largest cause of cancer deaths among women. at the same time, it is also among the most curable cancer types if it can be diagnosed early. this paper presents a novel hybrid intelligent method for recognition of breast cancer tumors. the proposed method includes three main modules: the feature extraction module, the classifier module and the optimization module. in t...

Considering a general vector optimization problem, we attach to it two new vector duals by means of perturbation theory. These vector duals are constructed with the help of the recent Wolfe and Mond-Weir scalar duals for general optimization problems proposed by R.I. Boţ and S.-M. Grad, by exploiting an idea due to W. Breckner and I. Kolumbán. Constrained and unconstrained vector optimization p...
