Machining of advanced ceramics in the green state aims to achieve complex geometry with near-net-shape dimensions minimizing machining steps after sintering, good surface finish, economic efficiency and flexibility, and ...

Coherent optical orthogonal frequency division multiplexing (CO-OFDM) has attracted a lot of interest in optical fiber communications due to its simplified digital signal processing (DSP) units, high spectral-efficiency, ...

The presence of precipitates in metallic materials affects its durability, resistance and mechanical properties. Hence, its automatic identification by image processing and machine learning techniques may lead to reliable ...

Overweight and obesity are considered a public health problem, as they are related to the risk of various diseases, and also to the risk of increased morbidity and mortality. The main objective of this work was to apply ...

This paper proposes a novel analytical framework based on the Fox H-function distribution. To test its efficacy we focus on a study case where we derive closed form expressions for the distribution of the end-to-end signal ...

A machine of milling belong of Federal University of Technology - Câmpus Ponta Grossa was been parked. A student group mentored by professor Doctor Marcelo Vasconcelos de Carvalho determined to carry out a retrofitting in ...

Decisions made by deans and university managers greatly impact the entire academic community as well as society as a whole. In this paper, we present survey results on which academic decisions they concern and the variables ...
