Uniform approach to selection of PID settings for heading and path tracking controllers that create a cascade control system ship autopilot is presented. Uniformity the design follows from observation each controlled plant looks like an integrator with time constant. In case controller, represented by known Nomoto model. Due elimination constant closed loop systems becomes 2nd order. One assume...

Parametric surface [Fari02] is a surface defined by a tensor-product of parametric curves, which are represented by parametric equations. As such surface comes with a well defined mathematical definition, it becomes one of the most common geometric tools for computer-aided geometric design and object modeling aids for many computer graphics applications. Typical examples of such surface include...

The uniform design is one of space filling designs and has been widely used in computer and industrial experiments. Many methods for construction of uniform designs or nearly uniform designs, such as the glp method, optimization method etc. have been proposed. A nearly uniform design is a design with low-discrepancy, where the discrepancy is a measure of uniformity. Various discrepancies have b...
