R/S analysis of pluviometric records: comparison with numerical experiments
(2001)
Hurst's exponent H is obtained for historical precipitation data in northeast Brazil. The influence of periodic natural forces in the data is reflected by the presence of breaks and steps in the plots of the R/S signal vs. ...
Numerical analysis of a modified evacuated tubes solar collector
(2012)
The need for renewable energy sources, facing the consequences of Climate Change, results in growing investment for solar collectors’ use. Research in this field has accompanied this expansion and evacuated tube solar ...

The van der Pol equation: qualitative and numerical study
(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2023)
Parametrical study of masonry walls subjected to in-plane loading through numerical modeling
(ELSEVIER SCI LTD, 2011)
This paper deals with the numerical assessment of the influence of parameters such as pre-compression level, aspect ratio, vertical and horizontal reinforcement ratios and boundary conditions on the lateral strength of ...
Back-analysis of slope failures by numerical techniques
(2016)
A method of defining strength parameters from slope failures is presented in this study, based on combining finite element and optimization analyses. The strength reduction technique is used to determine the shear strain ...
A cross-sectional study of low HIV testing frequency and high-risk behaviour among men who have sex with men and transgender women in Lima, Peru
(BioMed Central, 2015)
BACKGROUND: Increased HIV testing frequency among high-risk populations such as men who have sex with men (MSM) and male-to-female transgender women (TW) can lead to earlier treatment and potentially reduce HIV transmission. ...
