Evaluation of Quadrature Signal Generation Methods with Reduced Computational Resources for Grid Synchronization of Single-Phase Power Converters through Phase-Locked Loops
Low-cost single-phase grid connected converters require synchronization with the grid voltage to obtain a better response and protection under diverse conditions, such as frequency perturbations and distortion. Phase-locked ...
Stiffness of lipid monolayers with phase coexistence
(American Chemical Society, 2013-08)
The surface dilational modulus (or compressibility modulus) has been previously studied for monolayers composed of pure materials, where a jump in this modulus was related with the onset of percolation as a result of the ...
Phase-only optical encryption based on the zeroth-order phase-contrast technique
(SPIE-SOC PHOTOPTICAL INSTRUMENTATION ENGINEERS, 2009)
A phase-only encryption/decryption scheme with the readout based on the zeroth-order phase-contrast technique (ZOPCT), without the use of a phase-changing plate on the Fourier plane of an optical system based on the 4f ...

Precipitation of Laves phase in a 28%Cr-4%Ni-2%Mo-Nb superferritic stainless steel
(ELSEVIER SCIENCE INC, 2008)
The main objective of the present work was to study the precipitation of the Laves phase in the X1 CrNiMoNb 28 4 2 (Werkstoff-Nr. DIN 1.4575) superferritic stainless steel employing several complementary techniques of ...
Analysis of the Transformer Influence on a Three-Phase Dual Active Bridge DC-DC Converter
(Institute of Electrical and Electronics Engineers, 2016-07)
In this work, the impact of the high-frequency transformer on the three-phase dual active bridge DC-to-DC converter operation is investigated, using four transformers with different connections: star-star, delta-delta, ...
