Learning to cluster urban areas: two competitive approaches and an empirical validation
(2022)
Urban clustering detects geographical units that are internally homogeneous and distinct from their surroundings. It has applications in urban planning, but few studies compare the effectiveness of different methods. We ...

Hurst exponent estimation of self-affine time series using quantile graphs
(Elsevier B.V., 2016-02-15)
In the context of dynamical systems, time series analysis is frequently used to identify the underlying nature of a phenomenon of interest from a sequence of observations. For signals with a self-affine structure, like ...
A survey on direct solvers for Galerkin methods
(Sociedad Española de Matemática Aplicada, 2012-01)
In this paper we describe the history, performance, and design concepts of direct solvers for algebraic systems resulting from Galerkin discretizations of partial differential equations. Popular direct solver implementations ...
