Seasonality of the hydrological cycle in major South and Southeast Asian river basins as simulated by PCMDI/CMIP3 experiments
Shabeh ul Hasson, Valerio Lucarini, Salvatore Pascale +1
In this study, we investigate how PCMDI/CMIP3 general circulation models (GCMs) represent the seasonal properties of the hydrological cycle in four major South and Southeast Asian…
A Survey of Data Mining Techniques for Social Media Analysis
Mariam Adedoyin-Olowe, Mohamed Medhat Gaber, Frederic Stahl
Social network has gained remarkable attention in the last decade. Accessing social network sites such as Twitter, Facebook LinkedIn and Google+ through the internet and the web 2.…
Transience and recurrence of a Brownian path with limited local time and its repulsion envelope
Martin Kolb, Mladen Savov
In this note we investigate the behaviour of Brownian motion conditioned on a growth constraint of its local time which has been previously investigated by Berestycki and Benjamini…
Spectra of a class of non-self-adjoint matrices
E. Brian Davies, Michael Levitin
We consider a new class of non-self-adjoint matrices that arise from an indefinite self-adjoint linear pencil of matrices, and obtain the spectral asymptotics of the spectra as the…
An adaptive finite element method for the infinity Laplacian
Omar Lakkis, Tristan Pryer
We construct a finite element method (FEM) for the infinity Laplacian. Solutions of this problem may be singular, which has prompted us to conduct an a posteriori analysis of the m…
A McKean optimal transportation perspective on Feynman-Kac formulae with application to data assimilation
Yuan Cheng, Sebastian Reich
Data assimilation is the task of combining mathematical models with observational data. From a mathematical perspective data assimilation leads to Bayesian inference problems which…
