Abstract: During the last several decades, thermal insulation materials underwent considerable technological evolution owing to the needs of our civilisation, which drive the improvement of existing materials or the search for new ones that will satisfy the growing needs of the construction industry in terms of their quality and quantity. The innovations related to thermal insulation materials presented in this paper concern mainly the search for high-performance insulation materials but also the development of materials that will use natural resources in a sustainable manner.

Abstract: The article investigates the possibilities of applying machine learning algorithm to identify an individual through biometric voice recognition with the higher possible reliability. The emphasis in the analysis is placed on the possibility of using artificial intelligence approach methods for the purposes of recognizing a person unambiguously, uniquely on the basis of the data contained in his/her vocal spectral information. A large number of routes we can go to parametrically representing the speech signal for the voice recognition system such as Mel-Frequency Cepstrum Coefficients (MFCC). During the authentication phase the input voice signal is recorded and processed comparing it by using MFCC features with a signal that has been previously stored in the database by the same user. The main purpose is to compare some of the main machine learning algorithms to classify them on this particular application.
