Dinámica erosiva y aplicabilidad de modelos físicos de erosión en una cuenca de montaña mediterránea (Ribera Salada, Cuenca del Segre, Lleida, España)

open access: yesPirineos: Revista de Ecología de Montaña, 2000
[fr] On étudie la dynamique d'érosion de la surface du sol dans quelques versants de montagne de la source de la Ribera Salada (bassin du Sègre) en testant les modèles EROSION2D et EUROSEM. Trois usages du sol ont été différenciés: (1) Sous-bois du chêne

The publications of Ramon Margalef in Investigación Pesquera and Scientia Marina: The beginnings of marine ecology in the CSIC

open access: yesScientia Marina, 2020
Ramon Margalef López (1919-2004) was one of the most prominent scientists of the 20th century in the fields of limnology, oceanography and ecology. His contributions to theoretical ecology, which won him international recognition, were based on a great ...

Instability and dripping of electrified liquid films flowing down inverted substrates [PDF]

open access: yes, 2019
We consider the gravity-driven flow of a perfect dielectric, viscous, thin liquid film, wetting a flat substrate inclined at a non-zero angle to the horizontal.

Recent Design Optimization Methods for Energy-Efficient Electric Motors and Derived Requirements for a New Improved Method—Part 1

open access: yesProceedings, 2018
Energy-efficient electric motors are gathering an increased attention since they are used in electric cars or to reduce operational costs, for instance.

The Physics of the Vicsek model [PDF]

open access: yesThe European Physical Journal Special Topics, 2016
In these lecture notes, prepared for the Microswimmers Summer School 2015 at Forschungszentrum Juelich, I discuss the well known Vicsek model for collective motion and its main properties. In particular, I discuss its algorithmical implementation and the basic properties of its universality class. I present results from numerical simulations and insist

Precise probing and discrimination of third-generation scalar leptoquarks [PDF]

open access: yes, 2023
We explore the pair production of third-generation scalar leptoquark at the Large Hadron Collider to next-to-leading order accuracy in QCD, matched to parton shower for a precise probing of the stemming model.

Mekân Tabanlı Toprak Erozyonu Tahmin Modelleri: Bildiklerimiz Değişiyor Mu?

open access: yesCoğrafi Bilimler Dergisi, 2023
Soil erosion is a natural process that refers to the wearing top of the soil layer and transport to another place. This process has turned into an increasing spatial problem as human activities cause changes in the land cover.

Physical Modelling in MvStudium

open access: yesSNE Simulation Notes Europe, 2012
In this paper, we describe “physical” modeling technology in MvStudium that is a graphical environment for modeling and simulation of complex dynamic systems. MvStudium.6 modeling language (MVL) is based on open hybrid automata or Behavior-Charts (for short BCharts), functional diagrams, and supports object-oriented modeling. B-Chart is an extension of

A Model for Physical Nucleon [PDF]

open access: yesProgress of Theoretical Physics, 1962
The anomalous magnetic moment of nucleon is investigated by taking the possible ex­ citations of the nucleon core or the cloud pions into account. For the sake of definiteness and simplicity two assumptions are made: 1) the physical nucleon is composed of the static core accompanied by one or no cloud particle, 2) the virtual excitations can be treated

Simple QED- and QCD-like models at finite density

open access: yes, 2015
In this paper we discuss one-dimensional models reproducing some features of quantum electrodynamics and quantum chromodynamics at nonzero density and temperature.
