Simulating NEPs in a cluster with jNEP

This paper introduces jNEP: a general, flexible, and rigorous implementation of NEPs (the basic model) and some interestenting variants; it is specifically designed to easily add the new results (filters, stopping conditions, evolutionary rules, and so on) of the research in the area. jNEP is written in Java; there are two different versions that implement the concurrency of NEPs by means of the Java classes Process and Threads respectively. There are also extended versions that run on clusters of computers under JavaParty. jNEP reads the description of the currently simulated NEP from a XML configuration file. This paper shows how jNEP tackles the SAT problem with polynomial performance by simulating an ANSP.This work was supported in part by the Spanish Ministry of Education and Science (MEC) under Project TSI2005-08225-C07-06

Christiansen grammar evolution for the modelling of psychological processes

This is an electronic version of the paper presented at the International Industrial Simulation Conference (ISC 2007), held in Delft (The Netherlands)Psychologists have developed models of associative learning for more than 30 years. Despite the strong efforts made, they still suffer many shortcomings. We have tried to build an integral model of habituation, the simplest type of learning within the area of associative learning and the basic support for other types. To overcome the deficiencies of traditional models, we have made used of Christiansen Grammar Evolution. This evolutionary technique is capable of automatically search for a target expression (the model) in a given formal language (the formalism of the model). Under this perspective, that we call Automatic Modelling, we have found models of habituation with interesting characteristics.This work has been partially sponsored by the Spanish Ministry of Education and Science (MEC), project number TSI2005-08225- C07-06

Developing Tools for Networks of Processors

A great deal of research eort is currently being made in the realm of so called natural computing. Natural computing mainly focuses on the denition, formal description, analysis, simulation and programming of new models of computation (usually with the same expressive power as Turing Machines) inspired by Nature, which makes them particularly suitable for the simulation of complex systems.Some of the best known natural computers are Lindenmayer systems (Lsystems, a kind of grammar with parallel derivation), cellular automata, DNA computing, genetic and evolutionary algorithms, multi agent systems, arti- cial neural networks, P-systems (computation inspired by membranes) and NEPs (or networks of evolutionary processors). This chapter is devoted to this last model

Simulation of habituation to simple and multiple stimuli

Within the psychological literature there are a number of models that reproduce the defining properties of habituation to a single stimulus. However, most of them do not reproduce the phenomenon of dishabituation shown in empirical studies, consisting in the recovery of a stimulus previously habituated upon the appearance of a novel stimulus. The present work offers a model of habituation which, in addition to reproducing the basic properties of habituation to a stimulus, also does so when more than one stimulus is presented, and thus includes the dishabituation phenomenon. This model consists of two functions, one called “activation” and the other “availability”, and is tested by means of simulation of the responses in the context of different stimulus patterns. The results of the simulation show a good qualitative fit to the empirical results on the phenomena of habituation, including dishabituation. In addition, the model is suitable for inclusion in associative models that reproduce classical conditioning, which will make it possible in the future to incorporate into these the influence that the habituation of each stimulus may have on its association with other stimuli

Design and development of Iberia: a corpus of scientific Spanish

Iberia is a synchronic corpus of scientific Spanish designed mainly for terminological studies. In this paper, we describe its design and the infrastructure for its acquisition, processing and exploitation, including mark-up, linguistic annotation, indexing and the user interface. Two pre-processing tasks affecting a large number of words are described in detail: de-hyphenation and identification of text fragments in other languages. We also show how some of the reported statistics, namely, dispersion and association, are used for research on lexis.Peer reviewe

Teacher's Physical Activity and Mental Health During Lockdown Due to the COVID-2019 Pandemic

The COVID-19 pandemic has led teachers to an unpredictable scenario where the lockdown situation has accelerated the shift from traditional to online educational methods, and relationships have been altered by the avoidance of direct contact with the others, with implications for their mental health. Physical activity seemed to be a factor that could prevent mental disorders such as anxiety or depression in this peculiar situation. Therefore, the aims of this study were to explore how teachers have been affected by the lockdown with respect to their mental health and their relationships in three main fields: work, family, and social relationships, and to know which is the role of physical activity in the mentioned variables. For that purpose, an online survey was designed to collect quantitative and qualitative data. Results showed that indoor physical activity acts as preventive in lockdown situations, whereas the level of activity does not affect mental health. Also, teachers have experienced higher levels of distress due to the workload generated during the lockdown. In conclusion, to prevent health problems among teachers in future similar situations, it would be important to facilitate the practice of physical activity at home. Furthermore, teacher training in blended or online educational methods would be crucial for their favorable work development.SIN FINANCIACIÓN4.566 JCR (2020) Q1, 14/81 Physiology1.320 SJR (2020) Q2, 45/178 PhysiologyNo data IDR 2020UE
