Computer Simulations for Polymer Dynamics
1991
In this paper we review recent work on the dynamics of polymeric systems using computer simulation methods. For a two-dimensional polymer melt, we show that the chains segregate and the dynamics can be described very well by the Rouse model. This simulation was carried out using the bond fluctuation Monte Carlo method. For three-dimensional (3d) melts and for the study of hydrodynamic effects, we use a molecular dynamics simulation. For 3d melts our results strongly support the concept of reptation. A detailed comparison to experiment shows that we can predict the time and length scales for the onset of reptation for a variety of polymeric liquids. For a single chain, we find the expected h…
A New Colloid Model for Dissipative-Particle-Dynamics Simulations
2016
We propose a new model to simulate spherical colloids. This is a mesoscopic method based on the dissipative particle dynamics. The colloid is represented by a large spherical bead, and its surface interacts with the solvent beads through a pair of dissipative and stochastic forces. This new model extends the tunable-slip boundary condition [Eur. Phys. J. E 26, 115 (2008)] from planar surfaces to curved geometry, thus allows one to study colloids with slippery surfaces. Simulation results show good agreement with the prediction of hydrodynamic theories, indicating the hydrodynamic interactions are properly accounted in our new model.
Testing Mode-Coupling Theory for a Supercooled Binary Lennard-Jones Mixture I: The van Hove Correlation Function
1995
We report the results of a large scale computer simulation of a binary supercooled Lennard-Jones liquid. We find that at low temperatures the curves for the mean squared displacement of a tagged particle for different temperatures fall onto a master curve when they are plotted versus rescaled time $tD(T)$, where $D(T)$ is the diffusion constant. The time range for which these curves follow the master curve is identified with the $\alpha$-relaxation regime of mode-coupling theory (MCT). This master curve is fitted well by a functional form suggested by MCT. In accordance with idealized MCT, $D(T)$ shows a power-law behavior at low temperatures. The critical temperature of this power-law is t…
La libre circulación de resoluciones judiciales en la UE en el caso de la sustracción internacional de menores
2020
El presente artículo aborda la regulación actual y futura del sector del reconocimiento y ejecución de resoluciones extranjeras en materia de sustracción internacional de menores en el ámbito de la Unión Europea. Materia específica que motivó la previsión de un régimen de eficacia extraterritorial de resoluciones judiciales distinguido – y privilegiado – al del régimen genérico de las resoluciones en materia de responsabilidad parental. Recientemente, el instrumento aplicable en la materia, el Reglamento 2201/2003 (Reglamento Bruselas II bis) ha sufrido un importante proceso de reforma que ha culminado con la aprobación de un nuevo Reglamento, el Reglamento 2019/1111. En este trabajo aborda…
Mediation and Private International Law: Improving Free Circulation of Mediation Agreements Across the EU
2016
This paper, commissioned by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs upon request by the JURI Committee, examines the issues arising in the context of cross-border mediation. Cross-border litigation has increased steadily in recent years in Europe as a consequence of the consolidation of the European unification process. The enactment of Directive 2008/52/EC has certainly led to the presence of mediation legislation in the EU Member States. But many important differences can still be ascertained in relation to the legal framework developed, which affect key aspects of mediation. For mediation to obtain full endorsement by citizens in the fu…
The Application of Foreign Law by Judicial and Non-Judicial Authorities: Any News?
2020
The treatment of foreign law by judicial and non-judicial authorities constitutes “a crucial issue” for the proper functioning of any Private International Law (PIL) system. Nevertheless, and despite its relevance, international harmonization on this issue is scarce and old –usually, previous to 1980-, and it combines both a limited scope and little application. Thus, the nature granted to foreign law before national authorities, the way to ascertain its content or to consider when it has been sufficiently proved usually vary significantly among jurisdictions and negatively affect the potential application of foreign law. This situation is widespread. And it is even noticeable in a legally …
Spain: The Application of Foreign Laws in Spain – Critical Analysis of the Legal Novelties of 2015
2017
The Spanish system about treatment of foreign laws is regulated in different legal sources including the recent Act 29/2015 on International Legal Cooperation. The inconsistency between the mandatory nature of conflict of laws rules and the burden of parties of proving the foreign law makes the system unsatisfactory in the judicial scope whereas more flexible solutions -and consequently more satisfactory outcomes- can be evidenced in the non-judicial scope. This research approaches both scenarios from a legal and practical perspective and analyses the current solutions and some proposals of improvement.

The Convention For Choosing The Applicable Law – A Construction Specific For The Relationships Of Private Law With Foreign Element
2017
The legal relationships with foreign element generate the need to designate the law applicable in the conflict of laws. The national conflictual right and the European regulations govern the two complementary mechanisms for determining the law of the cause. Choosing the law by the parties gives expression to the subjective determination that, for some matters, is the rule, and for others, is the subsidiary solution. The recourse to the localization criteria of the applicable law signifies the objective determination of the law and contains variants that always lead to the identification of the lex causae. The method of concretizing the will of the parties is the choice convention of the app…
Integrated Simulation and Formal Verification of a Simple Autonomous Vehicle
2018
This paper presents a proof-of-concept application of an approach to system development based on the integration of formal verification and co-simulation. A simple autonomous vehicle has the task of reaching an assigned straight path and then follow it, and it can be controlled by varying its turning speed. The correctness of the proposed control law has been formalized and verified by interactive theorem proving with the Prototype Verification System. Concurrently, the system has been co-simulated using the Prototype Verification System and the MathWorks Simulink tool: The vehicle kinematics have been simulated in Simulink, whereas the controller has been modeled in the logic language of t…
