Two-dimensional cellular automaton model for the evolution of active region coronal plasmas
(Iop Publishing, 2015-02)
We study a two-dimensional cellular automaton (CA) model for the evolution of coronal loop plasmas. The model is based on the idea that coronal loops are made of elementary magnetic strands that are tangled and stressed ...
Space telescope and optical reverberation mapping project. VII. Understanding the ultraviolet anomaly in NGC 5548 with X-Ray spectroscopy
(IOP Publishing Ltd, 2017)
During the Space Telescope and Optical Reverberation Mapping Project observations of NGC 5548, the continuum and emission-line variability became decorrelated during the second half of the six-month-long observing campaign. ...
An electromechanical finite element model for piezoelectric energy harvester plates
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
Vibration-based energy harvesting has been investigated by several researchers over the last decade. The goal in this research field is to power small electronic components by converting the waste vibration energy available ...

Strength and power training did not modify cardiovascular responses to aerobic exercise in elderly subjects
(Associação Brasileira de Divulgação Científica, 2011-09-01)
Resistance training increases muscle strength in older adults, decreasing the effort necessary for executing physical tasks, and reducing cardiovascular load during exercise. This hypothesis has been confirmed during ...
Evaluación termodinámica y económica para la generación eléctrica por medio de la incineración de residuos sólidos urbanos
(Bucaramanga : Universidad de Santander, 2019Facultad de IngenieríaMaestría en Sistemas Energéticos Avanzados, 2019-10-24)
Currently, worldwide the constant generation of Municipal Solid Waste (MSW) has become a challenge for humanity that requires different management models. The objective of this research is to carry out a thermodynamic and ...
Probing the intra-group medium of a z=0.28 galaxy group
(OXFORD UNIV PRESS, 2017)
We present new MUSE observations of a galaxy group probed by a background quasar. The quasar sightline passes between multiple z = 0.28 galaxies, whilst showing at the same redshift low-ionized metal line species, including ...
Implementação de modulador para aumento de banda passante de um sistema de condicionamento de energia baseado em um conversor multinível
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAPrograma de Pós-Graduação em Engenharia ElétricaUFMG, 2021-10-08)
Power quality issues, while critical to the network and/or loads being powered, are not new. Voltage sags and swells, voltage and current unbalances, reactive current circulation and current and voltage distortions are ...
