Diamagnetic currents supported by collective charge waves in a class of Mott insulators
(1995)
We put forward a model of tightly bound electrons in a bipartite lattice with repulsive interaction between electrons of same spin located in neighboring sites. Assuming external magnetic field the stationary states are ...
Modelagem da capacitância de elementos magnéticos para elevadas frequências e classes de isolação
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2018-08-27)
This PhD thesis presents the development of models of magnetic elements for high frequency and insulation classes. Currently, there is an increasing demand for implementation of such elements as the power electronics has ...
Desenvolvimento de aplicativo baseado no método de Duval para análise de gases em transformadores
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2016-06-02)
This work proposes the development of an application on the analysis of gases dissolved in mineral transformer oil, of all classes of voltage and power, the Duval Triangle method. Through simulations in the application, ...
A 110 nA pacemaker sensing channel in CMOS on silicon-on-insulator
(IEEE, 2002)
The design of a sensing channel for implantable cardiac pacemakers in CMOS on silicon-on-insulator (SOI) technology is presented. The total current consumption is lowered to only 110nA thanks to the optimization at the ...
High Voltage Optical Sensor Insulation Using PLA (Polylactic Acid)
(Ieee, 2018-01-01)
Electric power systems, especially after the advent of smart grids, require intelligent voltage and current meters devoted to energy billing, control, protection and quality monitoring. Novel Optical Voltage Sensors (OVS) ...

Probing the Mott physics in kappa-(BEDT-TTF)(2)X salts via thermal expansion
(Iop Publishing Ltd, 2015-02-11)
In the field of interacting electron systems the Mott metal-to-insulator (MI) transition represents one of the pivotal issues. The role played by lattice degrees of freedom for the Mott MI transition and the Mott criticality ...
