Artificial Neural Networks and Machine Learning techniques applied to Ground Penetrating Radar: A review

Autor: S.L. Avila, Nathan Ida, X. L. Travassos

Publikováno v: Applied Computing and Informatics. 17:296-308

Ground Penetrating Radar is a multidisciplinary Nondestructive Evaluation technique that requires knowledge of electromagnetic wave propagation, material properties and antenna theory. Under some circumstances this tool may require auxiliary algorith

Electromagnetic Field Exposure Assessment in a Multi Source Telecommunication Environment

Autor: X. L. Travassos, S.L. Avila, Nathan Ida, S. Grubisic, A. Linhares

Publikováno v: Wireless Personal Communications. 110:2213-2225

RF-EMF exposure assessment carried out in an observatory open for general public visits, where there are multiple RF sources in the surrounding area. Fields at some points of interest have exceeded the ICNIRP exposure limits for the general public an
