Distortion Theorems Associated with Schwarzian Derivative for Harmonic Mappings
(SPRINGER BASEL AG, 2019)
Harmonic resonance in electrical grids with photovoltaic distributed generation
(2016-12-14)
In this paper it is presented the analysis of an electric power distribution branch containing a photovoltaic system, considering the generation and propagation of harmonic distortion. The obtained results refer to an ...
Effects on Light Efficiency in Discharge and Solid-State Lighting Operation, Supplied by No-Sinusoidal Voltage
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-01)
The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
Harmonic Resonance in Electrical Grids with Photovoltaic Distributed Generation
(Ieee, 2016-01-01)
In this paper it is presented the analysis of an electric power distribution branch containing a photovoltaic system, considering the generation and propagation of harmonic distortion. The obtained results refer to an ...
Effect of green machining on distortion and surface finishing in advanced ceramic
(2012-11-28)
An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after ...
Predicting the behaviour of structures under impact loads using geometrically distorted scaled models
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
When a scaled structure (model or replica) is used to predict the response of a full-size compound (prototype), the model geometric dimensions should relate to the corresponding prototype dimensions by a single scaling ...
A Power-Quality Index to Assess the Impact of Voltage Harmonic Distortions and Unbalance to Three-Phase Induction Motors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper discusses the need to simultaneously monitor voltage unbalance and harmonic distortions in addition to root-mean-square voltage values. An alternative way to obtain the parameters related to voltage unbalance ...
Internet search mechanisms and distortions of the semantic space: the scientific challenges facing the Googles
(2007)
Ever since the launch of Altavista, internet search engines have become a multi-billion dollar industry, with fierce competition between Google and the three major competitors. One of the challenges involved is to rank ...
