Numerical Bifurcation Analysis of Turing and Symmetry Broken Patterns of a Vegetation PDE Model
Konstantinos Spiliotis, Lucia Russo, Francesco Giannino +1
We study the mechanisms of pattern formation for vegetation dynamics in water-limited regions. Our analysis is based on a set of two partial differential equations (PDEs) of reacti…
Parsimonious Physics-Informed Random Projection Neural Networks for Initial-Value Problems of ODEs and index-1 DAEs
Gianluca Fabiani, Evangelos Galaris, Lucia Russo +1
We address a physics-informed neural network based on the concept of random projections for the numerical solution of IVPs of nonlinear ODEs in linear-implicit form and index-1 DAE…
Numerical Solution and Bifurcation Analysis of Nonlinear Partial Differential Equations with Extreme Learning Machines
Gianluca Fabiani, Francesco Calabrò, Lucia Russo +1
We address a new numerical scheme based on a class of machine learning methods, the so-called Extreme Learning Machines with both sigmoidal and radial-basis functions, for the comp…
Estimation of the effective reproduction number for SARS-CoV-2 infection during the first epidemic wave in the metropolitan area of Athens, Greece
Konstantinos Kaloudis, George A. Kevrekidis, Helena C. Maltezou +3
Herein, we provide estimations for the effective reproduction number for the greater metropolitan area of Athens, Greece during the first wave of the pandemic (February 26-Ma…
Analytical and Numerical Bifurcation Analysis of a Forest-Grassland Ecosystem Model with Human Interaction
Konstantinos Spiliotis, Lucia Russo, Francesco Giannino +1
We perform both analytical and numerical bifurcation analysis of a forest-grassland ecosystem model coupled with human interaction. The model consists of two nonlinear ordinary dif…
Modelling Lobbying Behaviour and Interdisciplinarity Dynamics in Academia
Stefano Mazzoleni, Lucia Russo, Francesco Giannino +2
Disciplinary diversity is being recognized today as the key to establish a vibrant academic environment with bigger potential for breakthroughs in research and technology. However,…
S&P500 Forecasting and Trading using Convolution Analysis of Major Asset Classes
Panagiotis Papaioannou, Thomas Dionysopoulos, Dietmar Janetzko +1
By monitoring the time evolution of the most liquid Futures contracts traded globally as acquired using the Bloomberg API from 03 January 2000 until 15 December 2014 we were able t…
A complex network theory approach for the spatial distribution of fire breaks in heterogeneous forest landscapes for the control of wildland fires
Lucia Russo, Paola Russo, Constantinos I. Siettos
Based on complex network theory, we propose a computational methodology that addresses the spatial distribution of fuel breaks for the inhibition of the spread and size of wildland…
Can social microblogging be used to forecast intraday exchange rates?
Panagiotis Papaioannnou, Lucia Russo, George Papaioannou +1
The Efficient Market Hypothesis (EMH) is widely accepted to hold true under certain assumptions. One of its implications is that the prediction of stock prices at least in the shor…
