The paper deals with the design of the robust PID controller for real uncertain Coupled-Tank process in the frequency domain. Only the first independent tank is considered (single-input single-output system). Robust controller is designed in two ways. The first approach is performed with the Edge Theorem and the Neimark’s D -partition method for the affine model and the second one is performed ...

We have recently proposed an extension of ADABOOST to regression that uses the median of the base regressors as the final regressor. In this paper we extend theoretical results obtained for ADABOOST to median boosting and to its localized variant. First, we extend recent results on efficient margin maximizing to show that the algorithm can converge to the maximum achievable margin within a pres...

Objectives The study considers how online home-based businesses offer opportunities for ethnic entrepreneurs to ‘break out’ of the traditional highly competitive and low margin sectors they are often associated with. Prior Work Previous studies have found a positive association between ethnic minorities high levels of entrepreneurship (Levie, 2007) and between home computer use and entrepreneur...

We 2 present a method for face class modeling in the eigenfaces space using a large-margin classifier like SVM. Another issue addressed is how to select the number of eigenfaces to achieve a good classification rate. As the experimental evidence show, generally one needs less eigenfaces than usually considered. We will present different strategies and discuss their effectiveness in the case of ...
