The most popular method for analyzing such signals is the empirical orthogonal functions (EOF) method. The method is based on the eigenvectors of the spatial cross-covariance matrix of a meteorological field. The EOF method, being linear, is optimal for feature extraction if the data are well characterized by a set of orthogonal structures or functions. Since the dynamics of climate are nonlinear the EOF may become inefficient. Several nonlinear methods for analyzing such fields are known. Here, the nonlinear analysis by using a neural network of the self-organizing map (SOM) structure is applied on the precipitation and the temperature data observed in the region of Yugoslavia.","PeriodicalId":347066,"journal":{"name":"6th Seminar on Neural Network Applications in Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132162435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The supplementary neuro-compensator is proposed to ensure a control system robustness and better controller adaptability upon the system uncertainties and model inaccuracies. This neural compensator is a part of integrated active control algorithm based on the centralized dynamic control strategy and full vehicle model. The fast convergence of learning process is achieved using standard back propagation method. The validity and effectiveness of the proposed method based on adaptive capability of neural compensator for a four wheel steering system have been demonstrated by simulation experiments.","PeriodicalId":347066,"journal":{"name":"6th Seminar on Neural Network Applications in Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113958811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The classification level is implemented with a single three-layer neural network, trained with the backpropagation algorithm and classifies the data into two classes: patients and control subjects.

The first of them consists in finding the so-called stress function, and the second one in finding the shear stresses on the basis of the formerly found stress function. The stress function is the solution of Poisson's partial differential equation for given conditions of unambiguity that in the elasticity theory describes the torsion of prismatic bars in terms of stresses. Modeling by means of electrical networks is one of a few possible ways to find the stress function. This paper describes how Chua and Yang's cellular neural networks can be used as an analogous model to find the stress function of a twisted prismatic bar, which serves to calculate the shear stress distribution. Effectiveness of the presented method is illustrated by the solutions of two problems. The method can be applied in mechanical and civil engineering.","PeriodicalId":347066,"journal":{"name":"6th Seminar on Neural Network Applications in Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116795022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present paper is concerned with the effect of magnetic stimulation of pineal complex on Na,K-ATPase activity in the same experimental model of AD. Since accumulating data indicate that free radicals mediate injury and death of neurons in AD, and because magnetic fields (MFs) can alter free radicals reactions, we tested the hypothesis that stationary MFs mediates ion homeostasis through membrane Na,K-ATPase activity. Results are presented as Vmax/Km parameters on erythrocyte membranes in peripheral blood of rats with lesioned nucleus basalis magnocellularis. Bilateral electrolytic or by kainic acid induced lesions of NBM induce significant decrease of Vmax/Km activity on erythrocyte membranes obtained by cardiac function. Stimulation of pineal complex of the brain more than ten days, by magnetic beads (600-Gauss flux density) fixed on the skull upon pineal gland, significantly increase impaired by lesions of NBM, Na,K-ATPase activity. Results are presented as Vmax/Km parameters on erythrocyte membranes in peripheral blood of rats with lesioned NBM of the basal forebrain bundle. These results confirm the hypothesis that altered ion homeostasis disturbed by neuro-degenerations play an essential role in pathogenesis of experimental AD and that magnetic stimulation of the pineal complex might successfully restore disturbed by neuronal death Na,K-ATPase activity.","PeriodicalId":347066,"journal":{"name":"6th Seminar on Neural Network Applications in Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114693844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
