Introduction to Geodetic Time Series Analysis
Machiel S. Bos, Jean-Philippe Montillet, Simon D. P. Williams +1
This contribution is the chapter 2 of the book "geodetic time series analysis" (10.1007/978-3-030-21718-1). The book is dedicated to the art of fitting a trajectory model to those…
A Curious History of Sunspot Penumbrae: An Update
V. M. S. Carrasco, J. M. Vaquero, R. M. Trigo +1
The ratio of penumbral to umbral area of sunspots is an important topic for solar and geophysical studies. Hathaway (Solar Physics, 286, 347, 2013) found a curious behaviour in thi…
Local fractality: the case of forest fires in Portugal
Mikhail Kanevski, Mário G. Pereira
The research deals with a study of local fractality in spatial distribution of forest fires in Portugal using the sandbox method. The general procedure is the following: (a) define…
From empirical data to continuous Markov processes: a systematic approach
Pedro Lencastre, Frank Raischel, Tim Rogers +1
We present an approach for testing for the existence of continuous generators of discrete stochastic transition matrices. Typically, the known approaches to ascertain the existence…
Modeling the functional network of primary intercellular Ca wave propagation in astrocytes and its application to study drug effects
Marcelo Pires, Frank Raischel, Sandra Vaz +3
We introduce a simple procedure of multivariate signal analysis to uncover the functional connectivity among cells composing a living tissue and describe how to apply it for extrac…
