A Bacterial-Based Algorithm to Simulate Complex Adaptative Systems
2014
Paper presented at the 13th International Conference on Simulation of Adaptive Behavior which took place at Castellón, Spain in 2014, July 22-25. Bacteria have demonstrated an amazing capacity to overcome envi-ronmental changes by collective adaptation through genetic exchanges. Using a distributed communication system and sharing individual strategies, bacteria propagate mutations as innovations that allow them to survive in different envi-ronments. In this paper we present an agent-based model which is inspired by bacterial conjugation of DNA plasmids. In our approach, agents with bounded rationality interact in a common environment guided by local rules, leading to Complex Adaptive Syste…
Four Remarkable Additions to the Biodiversity of Chinese Mosses
2022
Four species of moss genus Schistidium are reported for the first time from China. All of them have been found in the Xinjiang Uyghur Autonomous Region. Ecological and distributional details of the newly recorded species are provided and their local distribution is mapped. Photographs of the species are attached. Checklist of Schistidium species and identifying key are added. Considering the present records, Schistidium consists of 15 species in China.
Simulation-Based Analysis of "What-If" Scenarios with Connected and Automated Vehicles Navigating Roundabouts.
2022
Despite the potential of connected and automated vehicles (CAVs), there are still many open questions on how road capacity can be influenced and what methods can be used to assess its expected benefits in the progressive transition towards fully cooperative driving. This paper contributes to a better understanding of the benefits of CAV technologies by investigating mobility-related issues of automated vehicles operating with a cooperative adaptive cruise control system on roundabout efficiency using microscopic traffic simulation. The availability of the adjustment factors for CAVs provided by the 2022 Highway Capacity Manual allowed to adjust the entry capacity equations to reflect the pr…
Prey-predator strategies in a multiagent system
2006
This paper describes the prey-predator multiagent system which can be considered as an abstraction of more complex real-world models. Both the prey and the predators are considered as autonomous agents with their own behaviors and perception of the environment. In particular, we propose a simulator which lets study different strategies such as cooperation and individualism. An extensive experiment has been carried out in order to prove the effectiveness of the latter.
Entre la equidad y la conciliación: similitudes y disparidades en el diseño institucional del primer ciclo de educación infantil en España
2022
Versión en castellano e inglés La provisión del primer ciclo de educación infantil (EI a partir de ahora) ha aumentado de manera sostenida en España desde el año 2000. A pesar de una considerable dispersión territorial, esta expansión ha tenido lugar en todas las comunidades autónomas (CC. AA.). En este artículo estudiamos cómo los distintos diseños institucionales a escala autonómica impactan en la equidad tanto en el acceso al servicio como en el coste para las familias. Tratamos de averiguar en qué condiciones puede el primer ciclo de EI ir más allá de una política de conciliación empleo/familia y considerarse una política redistributiva y de igualdad de oportunidades que favorezca acced…
Contribution to the cooperative management of conflictual spaces between autonomous vehicles
2017
The continuous increase in the number of vehicles has constantly led to innovation to improve the regulation of road traffic. Today, vehicle automation and inter-vehicular communication make possible a new approach: the autonomous and cooperative intersection (ACI) in which autonomous vehicles communicate to negotiate their right of way at the intersection. Theoretically more effective, safer and more economical than traditional approaches, its implementation and deployment constitute a scientific and technological challenge. In this paper, we propose several contributions supporting this development: a longitudinal and lateral vehicle control strategy designed to work with information disc…
Mechanistic Investigations of the BZ Reaction with Oxalic Acid Substrate. I. The Oscillatory Parameter Region and Rate Constants Measured for the Rea…
2004
This paper is the first part of a study reinvestigating the mechanism of the Belousov-Zhabotinsky (BZ) reaction of oxalic acid, which is the simplest organic substrate for a BZ oscillator. New experiments are performed to find the oscillatory region in 1 M sulfuric acid at 20 °C. The removal rate of the end product bromine by an inert gas stream is a critical parameter here: oscillations can be observed only in a window of that parameter. The “rate constant” for the physical removal of bromine is measured as a function of the gas flow rate and reactor volume; furthermore, the rate constants of three component reactions important in this system are also determined. These are oxygen atom tran…
Automated agent-based system for weather information
2009
Road accidents are well correlated with bad weather conditions. In traffic management, several strategies have been considered in order to reduce this kind of accidents. Weather problems can cause difficult situations for the traffic management decision-makers. They need to analyze and absorb a large quantity of information in order to solve some problems due to bad weather. An automated agent-based system is a good solution to help decision-makers in the management of weather information to road users in relation to traffic conditions.In this paper, a distributed system based in autonomous agents and rules for road weather information has been proposed. Also the detection procedure is expl…
ANCORA SULLA PORTATA DELLA NOZIONE DI “CESSAZIONE DELL’ATTIVITÀ D’AZIENDA” A PROPOSITO DEL LICENZIAMENTO DELLA LAVORATRICE MADRE NEL CORSO DI UNA PRO…
2018
Con la sentenza annotata la Corte di Cassazione torna a pronunciarsi sulla corretta interpretazione di una delle eccezioni al divieto di licenziamento sancito dall’art. 54 D. Lgs. n. 151/2001, chiarendo che nell’ipotesi di cessazione dell’attività d’azienda non può intendersi ricompresa anche la cessazione dell’attività di un singolo reparto, seppur dotato di autonomia funzionale. Nel ripercorrere il ragionamento seguito dai giudici, la nota richiama alcuni importanti principi in materia di licenziamento delle lavoratrici madri nel periodo protetto. The judgment in question makes a remark about the meaning of the exception to the prohibition of dismissal, according to the article 54 D. Lgs.…
Autonomous Operation of Stationary Battery Energy Storage Systems—Optimal Storage Design and Economic Potential
2021
Global warming requires a changeover from fossil fuel based to renewable energy sources on the electrical supply side and electrification of the demand side. Due to the transient nature of renewables and fluctuating demand, buffer capacities are necessary to compensate for supply/demand imbalances. Battery energy storage systems are promising. However, the initial costs are high. Repurposing electric vehicle batteries can reduce initial costs. Further, storage design optimization could significantly improve costs. Therefore, a battery control algorithm was developed, and a simulation study was performed to identify the optimal storage design and its economic potential. The algorithm used is…
