A Eletricidade foi, ao longo da história humana, pensada e falada como se pertencesse a um domínio quase transcendental, algo simultaneamente além do espaço, do tempo e de qualquer concepção. O advento da ciência elétrica, ...

The assessment and prevention of floods require appropriate forecasting and knowledge of the related hydrological processes. Due to the similar form of the governing equations, flood hydrograph shows a clear analytical and ...

In this paper, the analog properties of advanced GaN/AlGaN High-Electron-Mobility Transistors (HEMTs) are studied as a function of temperature (T). The drain current, the threshold voltage, the transconductance and the ...

This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to ...
