Accelerated greenhouse gases versus slow insolation forcing induced climate changes in southern South America since the Mid‑Holocene
(Springer, 2016-03)
This paper is a pioneering analysis of past climates in southern South America combining multiproxy reconstructions and the state-of-the-art CMIP5/PMIP3 paleoclimatic models to investigate the time evolution of regional ...
Traceability of Acoustic Emission measurements for a proposed calibration method - Classification of characteristics and identification using signal analysis
(Elsevier, 2015)
When using Acoustic Emission (AE) technologies, tensile, compressive and shear stress/strain tests can provide a detector for material deformation and dislocations. In this paper improvements are made to standardise ...
An investigation into the isolation performance of mono-and bi-stable systems
(2014-01-01)
Motivated by the need for improving the isolation performance, many research studies have been performed on isolators with nonlinear characteristics. Based on the shape of their phase portrait, such devices can be configured ...
The Gradual Slide towards Homogeneity: The Influence of Convergence Forces
(2015)
Cultures and nations are losing their uniqueness to globalization forces as if they are indeed in a ‘global village’. Convergence forces of information explosion, ease of travel and transportation, and economic imperatives ...
The Big Gamble : The Migration of Eritreans to Europe
Why, every year, tens of thousands of people are willing to risk their lives in perilous voyages across Africa and the Mediterranean Sea? Why do they face such an ordeal to reach European countries where their long-term ...
Physiological quality of seeds of bean cultivars in terms of population densities
(Semina: Ciências Agrárias, 2018)
Locally Linearized methods for the simulation of stochastic oscillators driven by random forces
(Springer, 2017-03)
In this work, the performance of Locally Linearized integrators for the numerical simulation of stochastic oscillators driven by random forces is studied. This includes the reproduction of a number of dynamical properties ...
Análisis numérico de ecuaciones force-free en potenciales de Euler
(2021-04)
En este trabajo se presenta un estudio numérico de las ecuaciones de Force-Free en Potenciales de Euler las cuales conforman un sistema de ecuaciones mal puesto o débilmente hiperbólico. Esta característica da lugar a la ...
Proximity force approximation for the Casimir energy as a derivative expansion
(American Physical Society, 2011-11)
The proximity force approximation (PFA) has been widely used as a tool to evaluate the Casimir force between smooth objects at small distances. In spite of being intuitively easy to grasp, it is generally believed to be ...
Influence of gender and estrous cycle in the forced swim test in rats
(Pontifícia Universidade Católica do Rio de Janeiro (PUC-Rio)Universidade de Brasília (UnB)Universidade de São Paulo (USP), 2014)
