Experimental study of unconfined surface wave discharges at atmospheric pressure by optical emission spectroscopy
(Iop Publishing LtdBristolInglaterra, 2014)
Recent Eurasian river discharge to the Arctic Ocean in the context of longer-term dendrohydrological records
Mapped correlations between annual discharges (AD 1938–1990) of the major Eurasian rivers entering the Arctic Ocean (Severnaya Dvina, Pechora, Ob', Yenisey, Lena, and Kolyma) demonstrate a positive relationship between ...
Electrolocation-communication discharges of the fish Gymnotus carapo L. (Gymnotidae: Gymnotiformes) during behavioral sleep
(Associação Brasileira de Divulgação Científica (ABRADIC), 1999-10-01)
Technical problems have hampered the study of sleep in teleosts. The electrical discharges of Gymnotus carapo L. (Gymnotidae: Gymnotiformes) were monitored to evaluate their ease and reliability as parameters to study ...
Detection of partial discharges at field in SF6 insulated equipments
(Orlando, Florida, 2013-12-10)
This paper presents the results of research aiming to develop partial discharge detection techniques in high voltage equipment, at substation environment. Measurements of high frequency components of leakage current, at ...
Characteristics of Needle-Disk Electrodes Atmospheric Pressure Discharges Applied to Modify PET Wettability
(Ieee-inst Electrical Electronics Engineers Inc, 2017-05-01)
In the atmospheric pressure discharge with arrangement of a syringe needle, a capillary, and an external disk, it was observed different operation modes according to the relative position of the electrodes. With external ...
Low Cost System for Partial Discharge Monitoring in Power Transformers by Piezoelectric Sensors
(Ieee-inst Electrical Electronics Engineers Inc, 2016-07-01)
Partial discharge damages in power transformers require high cost monitoring procedures based on corrective maintenance or even interruptions of the power system. The development of online non-invasive monitoring systems ...
Análise distribuição da carga hidráulica e vazão na unidade operacional de um sistema de irrigação localizada
The different combination possibilities of emission uniformity and field slope within the operational unities of localized irrigation systems favor the occurence of some configurations in the irrigation system, and ...
Projected river discharge in the Euphrates−Tigris Basin from a hydrological discharge model forced with RCM and GCM outputs
The hydrological discharge (HD) model of Max Planck Institute for Meteorology is forced by a variety of climate model datasets to investigate the future of discharge in the Euphrates−Tigris Basin. The data include daily ...
