First Principles Attempt to Unify some Population Growth Models [PDF]

open access: yesarXiv, 2016
In this work, some phenomenological models, those that are based only on the population information (macroscopic level), are deduced in an intuitive way. These models, as for instance Verhulst, Gompertz and Bertalanffy models, are posted in such a manner that all the parameters involved have physical interpretation.

Autonomous vehicle decision and control through reinforcement learning with traffic flow randomization [PDF]

open access: yes
Most of the current studies on autonomous vehicle decision-making and control tasks based on reinforcement learning are conducted in simulated environments. The training and testing of these studies are carried out under rule-based microscopic traffic flow, with little consideration of migrating them to real or near-real environments to test their ...

Spin models as microfoundation of macroscopic financial market models [PDF]

open access: yesarXiv, 2011
Macroscopic price evolution models are commonly used for investment strategies. There are first promising achievements in defining microscopic agent based models for the same purpose. Microscopic models allow a deeper understanding of mechanisms in the market than the purely phenomenological macroscopic models, and thus bear the chance for better ...

From heterogeneous microscopic traffic flow models to macroscopic models [PDF]

open access: yesarXiv, 2019
The goal of this paper is to derive rigorously macroscopic traffic flow models from microscopic models. More precisely, for the microscopic models, we consider follow-the-leader type models with different types of drivers and vehicles which are distributed randomly on the road.

A local model for the optical energy and momentum transfer in dielectric media and the microscopic origin of Abraham's force density [PDF]

open access: yes
We report on the continuity equations for linear momentum and energy associated to a recently introduced electromagnetic formulation based on classical dipolar sources [Eur. Phys. J. Plus 138, 1034 (2023)]. When connected to the mass-polariton quasi-particle dynamics, these equations provide a consistent microscopic description of the local optical ...
