OPTIMAL RECOGNITION AND LOCALIZATION OF ACOUSTIC SOURCE USING ARTIFICIAL INTELLIGENCE METHODS


Тhe subject of the thesis is sound source recognition and sound source localization, in real conditions, using artificial intelligence algorithms. The main goal is optimal procedure for sound source observation using artificial neural networks for signal procesing, because of their extreme procesing speed. It has to provide implementation of hybrid system capable to recognize and locate sound source in the presence of disturbances. For the training and the testing of neural networks two sets of data are provided, from two different experiments, and to increase robustness genetic algorithm is applied. The results of the investigation will contribute the existing body of acoustic observation knowledge... More

NEAR FIELD ACOUSTIC LOCALIZATION UNDER UNFAVORABLE CONDITIONS USING FEEDFORWARD NEURAL NETWORK FOR PROCESSING TIME DIFFERENCE OF ARRIVAL


Coauthors: prof. dr Vlastimir Nikolic, Abdulathim Al-Noori, dr Ivan Ciric, dr Milos Simonovic

The paper investigates the performance of neural networks in modelling a hyperbolic positioning problem using a feedforward neural network as a representative. For experimental purposes, more than 2000 sound files were recorded by 8 spatially disposed microphones, for as many arbitrarily chosen acoustic source positions. The performance was examined in terms of different acoustic sensors setups, network configurations and training parameters. The experiment provided useful guidelines for the practical implementation of feedforward neural networks in the near-field acoustic localization... More

IMPROVING BLACK WELDED TUBE CLASSIFICATION PROCESS BY TRIZ METHOD




Coauthor: dr Aleksandar Miltenovic



This paper presents application of TRIZ method in improving the process of black welded tubes classification. At the moment the process of classification is performed by human operator so efficiency of classification depends of his working shape and concentration. Using innovative principles of TRIZ, on the basis of noticed technical contradictions several actions are performed in order to facilitate classification process, reduce working fatigue and consequently save working capabilities of human operator. Final goal is complete automation of black welded tube classification process. More
