Hitting and returning to rare events for all alpha-mixing processes
(ELSEVIER SCIENCE BV, 2011)
We prove that for any a-mixing stationary process the hitting time of any n-string A(n) converges, when suitably normalized, to an exponential law. We identify the normalization constant lambda(A(n)). A similar statement ...
Correlation Decay and Recurrence Asymptotics for Some Robust Nonuniformly Hyperbolic Maps
(2008)
We study a robust class of multidimensional non-uniformly hyperbolic transformations
considered by Oliveira and Viana (Ergod. Theory Dyn. Syst. 28:501–533, 2008).
For an open class of Hölder continuous potentials with small ...
Poincaré recurrence times in stochastic mixing processes
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2022-02-17)
In the context of the discrete-time stochastic processes, this thesis presents new results on Poincaré recurrence theory. After a complete review of recent results, we present a new theorem on the exponential approximations ...
Fluctuation bounds for entropy production estimators in Gibbs measures
(IOP Publishing, 2015)
We give bounds for the fluctuations of estimators of the mean entropy production
in Gibbsian sources. These bounds are valid for every n, where n
denotes the size-length of the sample. We consider two estimators which ...
Panorama de expansão de geração de energia através de painéis fotovoltaicos
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Física - EFi, 2021-06-28)
Starting with a brief explanation about the excitation of electrons in valence and conduction
band when a pn junction of a silicon crystal semiconductor with impurities is enlightened,
which its working state in reverse ...
Post-tsunami effects on different trophic levels in the shallow benthic community of Robinson Crusoe Island, Chile.
(2012)
On 27 February 2010, Robinson Crusoe Island was hit by a tsunami and here we examine
its effects on the shallow subtidal benthic community using data collected before and
after the tsunami. Since late 2008 we have been ...
Caribbean Report 19-01-1993
(The British Broadcasting Corporation, 1993-01-19)
In a statement in parliament Russell Huggins - Minister of National Security Trinidad and Tobago) denies allegations made by Scotland Yard that a drug cartel exists in the Trinidad and Tobago Police Force. He stated that ...
Desenvolvimento de dispositivo original para medição e registro de ondas de corrente de descargas atmosféricas
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAPrograma de Pós-Graduação em Engenharia ElétricaUFMG, 2020-05-12)
The acquisition of lightning-current waveforms is important for providing parameters required for lightning-protection design and for estimating effects resulting from lightning events. Currently, building and maintaining ...
