Effects of Bridges construction on the benthic invertebrates structure of the Delta Paraná River
(Interciencia, 2005-02)
Benthic assessment of lotic environments impacted by bridge and highway construction at the Paraná River Delta is reported. The purpose of the study was to examine the degree of impact of physical disturbances on benthic ...
Structural Behavior of Barges in High-Energy Collisions against Bridge Piers
(American Society of Civil Engineers, 2016-02)
The collision of barges against bridge piers is an extreme loading condition that usually governs the design of bridges that span navigable waterways. The magnitude and time variation of impact forces depend on several ...
Modulation strategy to operate the dual active bridge DC-DC converter under soft-switching in the whole operating range
(Institute of Electrical and Electronics Engineers, 2011-04)
A new modulation strategy that allows operating the dual active bridge (DAB) dc–dc converter under soft switching in the whole operating range is proposed. This strategy is ruled by imposing a certain modulation index in ...
The Normative Autonomy of Logic
(Springer, 2020-09-21)
Some authors have called into question the normativity of logic, using as an argument that the bridge principles for logical normativity (MacFarlane, In what sense (in any) is logic normative for thought, 2004)? are just ...
Light-induced healing in azobenzene bridged silsesquioxanes
(Pergamon-Elsevier Science Ltd, 2019-08)
Intrinsic healable polymers are materials capable of repairing itself through its chemical nature, in order to improve stability and durability and to restore the lost functionalities or properties. In this study, azobenzene ...
Control of a DC-DC Dual Active Bridge Converter in DC Microgrids Applications
(Institute of Electrical and Electronics Engineers, 2021-08)
In this paper, a control strategy for an isolated DCDC dual active bridge converter to adapt different voltage levels in a DC microgrid is proposed. The control strategy allows regulating the output voltage while maintaining ...
Semi-conductors faults analysis in dual active bridge DC-DC converter
(Institution of Engineering and Technology, 2016-05)
Failures in power semi-conductors of a dual active bridge converter are characterised considering open-circuit faults in diodes and transistors. A detailed electrical waveforms analysis to identify the main symptoms of the ...
Structural and spectroscopic evidence of strong electronic delocalization through a cyanido bridge in a mixed-valence Os-Ru complex
(Wiley VCH Verlag, 2010-12)
We report the properties of a trinuclear cyanido-bridged complex, trans-(dmap)4RuII(Âμ-NC)OsIII(CN) 524- [14-; dmap = 4-(dimethylamino)pyridine], whose structure and electronic and vibrational spectra present strong evidence ...
The VISCACHA survey: III. Star clusters counterpart of the Magellanic Bridge and Counter-Bridge in 8D
(EDP Sciences, 2021-03)
Context. The interactions between the Small and Large Magellanic Clouds (SMC and LMC) created the Magellanic Bridge; a stream of gas and stars pulled out of the SMC towards the LMC about 150 Myr ago. The tidal counterpart ...
Open Transistors Fault-Tolerant Schemes of three-Phase Dual Active Bridge DC-DC Converters
(Institute of Electrical and Electronics Engineers, 2021-03)
This work proposes fault-tolerant schemes for open-transistor faults applied to three-phase dual active bridge converters (TPDABC), using different transformers: star-star, delta-delta, and delta-star. The proposal consists ...
