Distflow based state estimation for power distribution networks
(2018-11-01)
A new state estimation method for electrical power distribution systems using the Distflow formulation and the Weighted Least Square method to determine the steady-state operating point is presented. In order to reduce the ...
Characterizing monthly temperature variability states and associated meteorology across southern South America
(Wiley-Blackwell, 2019-07-29)
Key spatiotemporal patterns of monthly scale temperature variability are characterized over southern South America using k-means clustering. The resulting clusters reveal patterns of temperature variability, referred to ...
Heart-rate variability in low-risk prematurely born infants reaching normal term: A comparison with full-term newborns
(1993)
To investigate the influence of prematurity and postnatal age on the maturation of the autonomic nervous system function, we analysed heart-rate and heart-rate variability in twelve prematurely born infants (<37 weeks ...
Complete state reconstruction of a two-mode Gaussian state via local operations and classical communication
(Amer Physical SocCollege PkEUA, 2009)
Homogeneous regions and sample size for attributes of the climate in Sao Paulo State, Brazil
(Univ Federal Santa Maria, 2008-05-01)
The purpose of this study was to separate homogeneous regions and to estimate the numbers of years necessary to evaluate the variables: sunshine, global solar radiation and photossintetically active radiation in Sao Paulo ...
Trends and rainfall tropicalization in Parana State, south of Brazil
(Centro Ciencias Atmosfera Unam, 2020-01-01)
In order to detect areas and periods of rainfall reduction and increase in Parana State, south of Brazil, the objective of this manuscript is to analyze, spatially and temporally, rainfall trends from 1976 to 2011. Monthly ...
Entropy variation in isothermal fluid flow considering real gas effects
(2011-01-01)
The present paper concerns on the estimative of the pressure loss and entropy variation in an isothermal fluid flow, considering real gas effects. The 1D formulation is based on the isothermal compressibility module and ...
Characterization and quantification of symmetric Gaussian-state entanglement through a local classicality criterion
(Amer Physical SocCollege PkEUA, 2005)
Lower bounds on the entanglement of formation for general Gaussian states
(American Physical SocCollege PkEUA, 2004)
The AT1 receptor antagonist losartan does not affect depressive-like state and memory impairment evoked by chronic stressors in rats
(2019-01-01)
The present study investigated the effect of the treatment with the angiotensin II type 1 receptor (AT1) antagonist losartan in the depressive-like state and memory impairment evoked by exposure to either homotypic (i.e., ...
