La universidad europea se encuentra inmersa en un proceso de convergencia hacia un Espacio Europeo de Educación Superior que posibilite el reconocimiento mutuo de titulaciones y el establecimiento de equivalencias, competencias y cualificaciones comunes y que fomente un cambio tanto en las metodologías y actividades docentes como en las...

Here we report new results of a genetic algorithm (GA) used to evolve one dimensional Cellular Automata (CA) to perform a P3 non-trivial collective behavior task. For this task the goal is to find a CA rule that reaches one final configuration in which the concentration of active cells oscillates among three different values. Though the...

In this paper, we present a cellular automata model for a two-level laser which includes a saturable absorber. We show that the model reproduces laser passive Q-switching, a behavior in which intense short pulses of laser radiation are produced. Depending on the concentration of the absorbent, the automaton model qualitatively reproduces two...

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and...

Laser dynamics simulations have been carried out using a cellular automata model. The Shannon's entropy has been used to study the different emergent behaviors exhibited by the system, mainly the laser spiking and the laser constant operation. lt is also shown that the Shannon's entropy of the distribution of the populations of photons and...

We investigate in the framework of the semiclassical approximation the relative importance onf the Coulomb and nuclear fields to induce the break-up of neutron rich nuclei such as LI at energies close to the Coulomb barrier. We assume that the mechanism that leads to the separation is the excitation of a low-lying dipole mode in wich the...

Laser dynamics is traditionally modeled using differential equations. Recently, a new approach has been introduced in which laser dynamics is modeled using two-dimensional Cellular Automata (CA). In this work, we study a modified version of this model in order to simulate the dynamics of pulsed pumped lasers. The results of the CA approach are...

Cellular automaton models of complex systems (CSs) are gaining greater popularity; simultaneously, they have proven the capability to solve real scientific and engineering applications. To enable everybody a quick penetration into the core of this type of modeling, three real applications of cellular automaton models, including selected...

The long-established approach to study laser dynamics uses a set of differential equations known as the laser rate equations. In this work we present an overview of an alternative model based on a cellular automaton (CA). We also present a panorama of different variants of the model: the original one, designed to simulate general laser...

We investigate the relative importance of the Coulomb and nuclear fields to induce the break-up of neutron-rich nuclei such as 11 Li at energies close to the Coulomb barrier. We assume that the mechanism that leads to the separation is the excitation of a low-lying dipole mode in which the weakly-bound neutron halo performs a collective...

The different kinds of behavior exhibited by the system in a laser dynamics simulation using a cellular automata model are analyzed. Three distinct types of behavior have been found: laser constant operation, laser spiking and a complex behavior showing irregular oscillations. In the last case, the power spectrum follows a power law of the type...

This paper presents a study of performance of RAM-based implementations in FPGAs of Finite State Machines (FSMs). The influence of the FSM characteristics on speed and area has been studied, taking into account the particular features of different FPGA families, like the size of LUTs, the size of memory blocks, the number of embedded...

A nivel mundial, la robótica educativa está cada vez más presente en los centros educativos de todo el mundo, sobre todo a niveles de educación secundaria, incluso ya hay bastantes experiencias de introducción en el currículum en infantil y en primaria. En España, la robótica educativa se ha ido incorporando como una actividad extraescolar,...

The classical modeling approach for laser study relies on the differential equations. In this paper, a cellular automaton model is proposed as an alternative for the simulation of population dynamics. Even though the model is simplified it captures the essence of laser phenomenology: (i) there is a threshold pumping rate that depends inversely...

This paper presents an analysis on the performance of a parallel implementation of a discrete model of laser dynamics, which is based on cellular automata. The performance of a 2D parallel version of the model is studied as a rst step to test the feasibility of a parallel 3D version, which is needed to simulate speci c laser systems. The...

In this chapter we review the use of a biologically inspired heuristic technique— cellular automata (CA)—as a problem solver for one of the most paradigmatic complex systems: the laser. CAs are a class of mathematical system that can be used to model spatiotemporal phenomena, characterized by the discreteness of all of its variables: space,...

Introduction to the proceedings of the 15th edition of the European Alliance for Innovation (EAI) International Conference on Simulation Tools and Tech niques (SIMUtools 2023).

Firstly, the application of a cellular automata (CA) model to simulate the dynamics of lasers is reviewed. With this kind of model, the macroscopic properties of the laser system emerge as a cooperative phenomenon from elementary components locally inter-acting under simple rules. Secondly, a parallel implementation of this kind of model for...

In this chapter we present some remote services for advanced problem optimization. These tools permit us to get a set of resources useful to approach problems easily using the Internet as a channel of experimentation with the optimization algorithms involved.

The classical point of view to study the laser dynamics are the Maxwell-Bloch equations however the CA models are complementary tools that represent an advantage in cases in which the system of differential equations have convergence problems.

A parallel implementation for distributed-memory MIMD systems of a 2D discrete model of laser dynamics based on cellular au- tomata is presented. The model has been implemented on a PC cluster using a message passing library. A good performance has been obtained, allowing us to run realistic simulations of laser systems in clusters...

A Cellular Automaton is a bio-inspired discrete model of computation with multiple applications, consisting of a regular grid of cells that have different states a long time. Our research group at the University of Seville(Spain)collaborated in the past with Prof. Mohammad S. Obaidat in the fusion of Cellular Automata(CA) with another...

We present an analysis of the feasibility of executing a parallel bioinspired model of laser dynamics, based on cellular automata (CA), on the usual target platform of this kind of applications: a heterogeneous non-dedicated cluster. As this model employs a synchronous CA, using the single program, multiple data (SPMD) paradigm, it is not clear...
