Estudo, controle e modelagem do conversor dual active bridge (dab) para conexão no sistema elétrico de potência
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-02-18)
This work proposes to design, analyze and develop a bidirectional DC-DC converter
to perform the interface between a renewable source (wind or solar for example) and a
battery bank so that the power flow through this ...
Modelagem e controle do conversor DAB para interface entre banco de baterias e sistema elétrico de potência
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-08-07)
This Master's Dissertation presents the development of a Dual Active Bridge (DAB) converter for charging a battery bank, which is connected to a DC bus, which is connected to the electric power system by means of an inverter. ...
Projeto do conversor Dual Active Bridge (DAB) para o carregamento de banco de baterias
(Universidade Federal de Santa MariaBrasilUFSMColégio Técnico Industrial de Santa Maria, 2023-02-02)
This undergraduate final work has the objective of designing the Dual Active Bridge (DAB) converter for the charging of a battery bank. The traditional DAB converter will be used with the addition of an output inductance ...
Ultrasensitivity in signaling cascades revisited: Linking local and global ultrasensitivity estimations
(Public Library of Science, 2017-06)
Ultrasensitive response motifs, capable of converting graded stimuli into binary responses, are well-conserved in signal transduction networks. Although it has been shown that a cascade arrangement of multiple ultrasensitive ...
Mathematical Prediction of Cooling Rates during Cryopreservation of Reproductive Cells in Liquid Nitrogen
(Nova Science Publishers, 2015)
Liquid nitrogen is one of the cryogenic fluids most used for cryopreservation of animal germoplasm; low temperature preservation of oocytes, sperm and embryos is a fundamental cornerstone of assisted reproductive technologies. ...
Desarrollo de un simulador de panel fotovoltaico mediante un conversor DC-DC
(2020-09)
The study and evaluation of stages in photovoltaic systems is made difficult by the changing meteorological conditions, not allowing the planning of the work, large spaces are also needed to install the panels and high ...
Intuitionistic fuzzy set and fuzzy mathematical morphology applied to color leukocytes segmentation
(Springer, 2019-10-25)
This work presents a new algorithm based on Atanassov’s intuitionistic fuzzy sets and fuzzy mathematical morphology to leukocytes segmentation in color images. The main idea is based on modeling a color image as an Atanassov’s ...
Multisite phosphorylation provides an effective and flexible mechanism for switch-like protein degradation
(Public Library of Science, 2010-12)
Phosphorylation-triggered degradation is a common strategy for elimination of regulatory proteins in many important cell signaling processes. Interesting examples include cyclin-dependent kinase inhibitors such as p27 in ...
Discrete Anatomical Coordinates for Speech Production and Synthesis
(Frontiers Media, 2019-04)
The sounds of all languages are described by a finite set of symbols, which are extracted from the continuum of sounds produced by the vocal organ. How the discrete phonemic identity is encoded in the continuous movements ...
Theoretical study and demonstration of photonic asynchronous first-order delta-sigma modulator for converting analog input to NRZ binary output
(John Wiley & Sons Inc, 2015-01-23)
A novel photonic analog-to-digital converter based on asynchronous first-order delta-sigma modulation (ADSM) has been theoretically investigated and experimentally demonstrated. The architecture uses an optical leaky ...
