Solid wood floors are very common in interior decoration, and their color is an important indicator of product quality, selected order to achieve the overall aesthetic needed ensure consistency. In realize sorting solid based on depth, so that colors could be freely graded, one image acquisition system was built collect 108 floor images a set fast methods for depth developed. Among these, 10 we...

Analyzing a nonlinear system on high dimensions is not simple, especially with the practical applications. Since the prediction of the output from the dynamical system can be formulated as a regression problem, many previous attempts have been made to solve this regression. With the assumption of nonlinearity in the system, we attempt to apply encoding method, such as sparse coding or local coo...

This paper deals with the identification of nonlinear systems using multi-kernel approach. In this context, we have improved the Support Vector Regression (SVR) method in order to identify nonlinear complex system. Our idea consists in dividing the regressor vector in several blocks, and, for each one a kernel function is used. This blockwise SVR approach is called Support Kernel Regression (SK...

An effective system testing activity for consecutive releases of very large software systems depends considerably on the selection of test cases for execution. From a practical point of view, it is not feasible to run all possible test cases because of the real-world constraints of limited time, human and monetary resources. While existing techniques for test case selection provide methods to l...

1 2 During regression testing, a modified system is often retested using an existing test suite. Since the size of the test suite 3 may be very large, testers are interested in detecting faults in the modified system as early as possible during this retesting 4 process. Test prioritization attempts to order tests for execution so that the chances of early detection of faults during retest5 ing ...
