The study presents a new approach to non-invasively identify the 3-dimensional MI substrate from the equivalent current densities (ECDs) that is inversely reconstructed from body surface potential maps (BSPMs). The MI substrate was characterized using a threshold determined from the ECD magnitude. A total of 114 sites of transmural infarctions, 91 sites of epicardial infarctions, and 36 sites of endocardial...
The central pattern generator(CPG) is used to control robot very well. But the adjustment of CPG parameters and it's interaction with the external inputs are still open problems. Based on biological knowledge, the central nervous system rules the switch of the CPG modes. In this paper we focus on the coupling relationship between the cerebral cortex and the CPG and establish the mathematical model...
To eliminate flood disaster, which happened more and more frequently in China, a fuzzy-inference based neural network model is developed. This model can solve the problems of systematic difficulty, inefficiency, shortcomings of unable to self-study and inadequate in traditional method. Firstly, the detailed steps of forming the new model were given. Secondly, a case study was used to demonstrate how...
The best utilization order of multi-water resources is the key point of water resources allocation. The considered assessment indexes include not only the quantitative elements, but also the qualitative elements which are difficult to be quantized. Based on the semi-structured and multi-objective fuzzy optimization theory, this paper sets up a model which evaluates synthetically the proper order of...
In order to develop management experiments, we integrate computer environment with role-playing, and propose a modeling method called similarity-extension modeling method, by which we found a novel way to transform an economic experiment into a management one. In the paper, the basic steps of similarity-extension modeling are improved, and their applications are illustrated by taking Cournot Oligopoly...
We have developed a new surface-source model to account for the bioelectrical potential on the body surface. A two-dimensional representation of three-dimensional bioelectrical sources has been developed using an equivalent surface charge model. The proposed equivalent surface charge mapping technique has been evaluated by computer simulations and applied to body surface Laplacian mapping data.
We have developed a new technique to estimate inverse multiple dipole solutions from body surface Laplacian maps (BSLMs). The surface Laplacian of the body surface potential has been employed to estimate equivalent dipoles. It is found, through computer simulations, that the inverse multiple dipole solutions using the BSLMs have much greater spatial resolution than those using body surface potential...
