The assessment of the quality of sugar using electronic tongue and machine learning algorithms

The correct classification of sugar according to its physico-chemical characteristics directly influences the value of the product and its acceptance by the market. This study shows that using an electronic tongue system along with established techniques of supervised learning leads to the correct classification of sugar samples according to their qualities. In this paper, we offer two new real, public and non-encoded sugar datasets whose attributes were automatically collected using an electronic tongue, with and without pH controlling. Moreover, we compare the performance achieved by several established machine learning methods. Our experiments were diligently designed to ensure statistically sound results and they indicate that k-nearest neighbors method outperforms other evaluated classifiers and, hence, it can be used as a good baseline for further comparison. © 2012 IEEE.

A arte nas ondas do rádio: ações e procedimentos para esta prática

This paper proposes an extension of the personal experience of the listener through radio. The radio, because it is a medium of reaching, disseminating and having considerable accessibilities towards the production of its contents, and if exploited, could very well combine functionality with aesthetics in the production and broadcasting of programs, something that makes the radio not only a means for transmission of information. In the production of dramatic art, for example, the use of other elements, such as sound effects, may suggest form and consistency to the object described during the practice of radio utterance. The proper combination of function and aesthetic in music, sound effects and voiceover radio can change the mood of the listener and even promote their creativity.
