Efficient inference for agent-based models of real-world phenomena

2021
The modelling of many real-world problems relies on computationally heavy simulations. Since statistical inference rests on repeated simulations to sample the parameter space, the high computational expense of these simulations can become a stumbling block. In this paper, we compare two ways to mitigate this issue based on machine learning methods. One

Modelling and simulation of electrical phenomena in a real time test bench

2018 53rd International Universities Power Engineering Conference (UPEC), 2018
The energy transition main targets are increase of energy efficiency and promotion of renewable technologies, hence the number of components with power electronics is growing in the electrical system. The research project VEREDELE examines these effects and resulting interactions in order to identify possible challenges and develop suitable solutions ...

Critical phenomena in real magnetic crystals: Correlation functions in spatially non-homogeneous ising models

Journal of Magnetism and Magnetic Materials, 1980
Abstract In a simple two-dimensional Ising model for the critical behaviour of magnetic crystals with layer- or surface-like lattice imperfections, the modification of the energy density correlation function and its consequences for the temperature dependence of the specific heat are studied in detail; some results on the spin-spin correlation are ...

Real-space renormalization group and critical phenomena in the two-dimensional spin-12X−Ymodel

Physical Review B, 1978
A new formulation of the renormalization-group in real space, suitable for quantum spin systems is proposed. The method is applied to the two-dimensional spin-$\frac{1}{2}$ $X\ensuremath{-}Y$ model on a triangular lattice, the renormalization-group transformation being evaluated up to second order in an appropriate cumulant expansion. To first order an

A Comprehensive Review of Fractional Calculus in Modeling Real-World Phenomena

Communications on Applied Nonlinear Analysis
Fractional calculus, an extension of classical calculus to non-integer orders of differentiation and integration, has garnered significant attention for its remarkable ability to model complex real-world systems. Unlike traditional integer-order models that can oversimplify or neglect certain memory and hereditary properties, fractional calculus ...

Representations of Real-World Phenomena: Modeling as a Transdisciplinary Formative Skill and Practice

2017
Late in the summer of 2013, Elon Musk set the Internet ablaze with a “napkin sketch” of the Hyperloop Alpha, his futuristic vision for mass transit (Christensen, 2013). Musk backed his rudimentary doodle with a 57-page memo where he aimed to keep “numbers to a minimum and avoid formulas and jargon” and apologized, “in advance for [his] loose use of the
