Logística reversa de equipamentos eletrônicos no final da vida útil na UFSM
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2017-12-06)
With the development and advance of technology year after year, thousands of electronic equipment such as cell phones, computers and televisions have become obsolete and therefore disposed of as waste in many different ...
Scanning electron microscopic and profilometric study of different sharpening stones
(2006-12-01)
Scaling and root planing contribute to the recovery of periodontal health. All periodontal instruments loose their fine cutting angle after use. To maintain this angle, correct sharpening is required using specifically ...

Setting the preheating process of electronic ballasts for hot-cathode fluorescent lamps, considering the Rh/Rc ratio
(2006-12-01)
This paper presents a new model for the representation of the electrodes filaments of fluorescent lamps, during their preheating, and an analysis capable to guide the design of the preheating process in electronic ballasts. ...
Protection Of Electronic Equipment Inside Buildings: A Hidden Source Of Damages
(IEEENew York, 2016)
Electronic error reduction system for clamp-on probes and measuring current transformers
(IEEE, 2000)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1999)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
Estimating the generation of waste electrical and electronic equipment in organizations: The case of a Brazilian federal agency
(2021-12-01)
The generation of waste electrical and electronic equipment (WEEE) has become a globally serious problem. Its adequate management has great importance for governments and organizations alike. Despite the available literature ...
