A Rule-Based Multi-agent System for Road Traffic Management
2009
Road Traffic presents a high dynamism which makes necessary the development of traffic management and control strategies to improve traffic flows and more important, road safety. This dynamism makes necessary the use of intelligent systems to support traffic organizations and road operators to cope with incidents. In this paper we introduce a new expert system to support traffic management when weather problems occur in the road network. The system uses multiagent technology to work with the specific characteristics of traffic domain and is able to work in two modes: a) coordinately, where all the agents works to solve problems in large networks and b) locally where due to communications pr…
A Monitoring and Management System for Energy Storage Integration in Smart Grids
2019
The integration of distributed storage systems (DSSs) at users and prosumers level can significantly contribute to energy efficiency and increase profits from renewable energy exploitation, thanks to suitable scheduling of charging and discharging periods. On the other hand, to preserve network stability and secure operation, Distribution Systems Operators (DSOs) are interested in DSSs control and cooperation with the grid. In this framework this work proposes a simple monitoring and management system for DSSs scheduling and its integration in a distributed measurement and control system architecture for smart grids. In the paper the proposed algorithm is tested on a simple case study at ho…
Energy Management Systems and tertiary regulation in hierarchical control architectures for islanded microgrids
2015
In this paper, the structure of the highest level of a hierarchical control architecture for micro-grids is proposed. Such structure includes two sub-levels: the Energy Management System, EMS, and the tertiary regulation. The first devoted to energy resources allocation in each time slot based on marginal production costs, the latter aiming at finding the match between production and consumption satisfying the constraints set by the EMS level about the energy production in each time slot. Neglecting the efficiency of the different energy generation systems as well as that of the infrastructure for electrical energy distribution, the problem dealt with by the EMS sub-level is linear and can …
Análisis bibliométrico y sistémico de la relación entre la gestión y el carbono
2022
[EN] This paper aims to present a bibliometric and systemic analysis of the Bibliographic Portfolio (BP) jointly examining the literature related to topics like “Greenhouse gas,” mainly carbon, and “Management,” as published in databases data such as Web of Science and Scopus in the field of economic and social sciences. The Knowledge and Constructivist Development Process methodology —Proknow-C— was used to establish the final portfolio and through the VosViewer program were mapped the various groups or relationships between the studied literature. The paper presents the theoretical and methodological aspects focusing on the areas and countries of study and highlighting the most relevant a…
The concept of genre within the critical approach to information systems development
2001
Abstract Jurgen Habermas' Critical Social Theory is regarded as a potential approach to information systems development (hereinafter referred to as the critical approach). However, the theoretical promise of this approach has not yet been operationalized in practice. This paper discusses the potential of the genre theory of organizational communication as a conceptual basis for doing so, using two studies that applied genre concepts to analyses and debates on document management. In particular, the paper illustrates the capability of genre concepts in responding to pleas for three types of rationality — communicative, emancipatory, and formal — considered fundamental to any method of inform…

Mācību vadības sistēmu integrācija angļu valodas stundās 10.klasē organizācijas un klasvadības uzlabošanai
2018
Pētījuma mērķis – rast iespējas svešvalodu skolotājiem uzlabot mācību procesa organizāciju, tai skaitā palielinot iespējas pārraudzīt katra skolēna sekmes un piesaistīt pastāvīgu uzmanību mācību procesam. Pētījuma ietvaros darba autorei bija iespēja izmēģināt un salīdzināt trīs dažādas mācību vadības sistēmas svešvalodu mācību procesā, kas veicina skolēnu interesi mācību stundās, fokusējoties uz jauno vielu. Vienlaicīgi tiek atvieglots skolotāja uzdevums apkopot un analizēt pārbaudes darbu rezultātus, lai turpmākajā mācību vielas apguves procesā koncentrētos uz skolēnu vājākajām zināšnām. Pētījums notika vispārizglītojošās skolas 10. klasē un ilga vairāk kā trīs mēnešus. Pētījuma noslēgumā …
From Rhetoric to Practice: The Case of Spanish Local Government Reforms
2013
This paper aims to explore what performance management tools are implemented in practice in Spanish local governments and whether they have led to an improvement in public management and accountability. We also analyse the usefulness of performance reporting, comparing it with that of accrual financial reporting. The results show that most of the entities that have introduced performance indicators do not use them for decision-making or accountability. After two decades of reforms in financial and management systems, financial directors still consider that budgetary reporting is the most useful, basically because the control of expenditure is still based on the budget.
Irrigation and Political Power in the Medieval Kingdom of Valencia
2018
The medieval Kingdom of Valencia (Spain) was a European feudal society born in the thirteenth century out of the military conquest of the east of al-Andalus by the Crown of Aragon. This work focuses on the social organization of irrigation institutions in the thirteenth, fourteenth, and fifteenth centuries, which replaced the water management systems in use during the Andalusi period. The study analyzes the three types of water-governance systems in operation: irrigation systems managed by royal officials, irrigation systems managed by municipalities, and irrigation systems managed by corporations of autonomous farmers. The chapter also examines the different royal and municipal officials t…
High Accuracy Modelling of Hybrid Power Supplies
2011
This chapter proposes a modelling approach based on the PSIM/Simulink co-simulation toolbox for hybrid power supplies, featuring high accuracy. Hybrid source performances are fully tested during behavioural simulations. The importance of high-accuracy modelling is investigated and modelling guidelines for both power sources and load are given for further applications. The Simulink model is analyzed and the efficiency of the proposed approach is verified by the comparison between simulation and experimental results. In the last few years, hybrid power supplies are investigated for a wide variety of application areas: two primary sources are coupled to take advantages of both, overcoming thei…
