the aim of this study is to evaluate how far lempel-ziv complexity (lzc) of the binary symbolic sequences resulting from static or dynamic transformation (partitioning first-order difference) of the short-term electrocardiogram (ecg) signals (only 2 seconds duration) has the  potential in discriminating normal and ventricular tachycardia/ventricular fibrillation (vt/vf) subjects. the statistica...

The complex-step method for calculating sensitivities and its use in numerical algorithms is presented. A general procedure for the implementation of this method is described in detail and a script is developed that automates its implementation. The numerical examples include the automatic conversion of a structural finite element and a two-dimensional computational fluid dynamics code. In both...

Automatic control deals with the development and the implementation of methods leading to automatic decision processes, for the purpose of improving the performance of industrial, biological, socio-economical systems. The basic principle of automatic control is feedback: information on the state of a system is collected (sensors) and actions on a system is exerted (actuators) so as to influence...

We present new tools for the segmentation and analysis of musical scores in the OpenMusic computer-aided composition environment. A modular object-oriented framework enables the creation of segmentations on score objects and the implementation of automatic or semi-automatic analysis processes. The analyses can be performed and displayed thanks to customizable classes and callbacks. Concrete exa...

The geological section map uses the specified elements to express characteristics and attributes of body at a certain depth below line. By analyzing functional requirements automatic drawing system, structure modules system are designed in detail. was developed with AutoCAD as platform C# development language help CAD secondary technology. Taking Xishimen iron ore mine an example, proved be eff...
