A Cooperative Multi-Agent System for Crowd Sensing Based Estimation in Smart Cities

2020

The concept of Smart City has spread as a solution to ensure better access to information and services to citizens, but also as a means to reduce the environmental footprint of cities. To this end, a continuous and wide observation of the environment is necessary to analyze information that enables government bodies to act on the environment appropriately. Moreover, a diffused acquisition of information requires adequate infrastructure and proper devices, which results in relevant installation and maintenance costs. Our proposal enables reducing the number of necessary sensors to be deployed while ensuring that information is available at any time and anywhere. We present the HybridIoT syst…

Les crânes déformés de Saint-Etienne (Beaune, Côte d'Or, Ve-VIe siècles). Données archéologiques et anthropologiques

1995

The sector of the Saint-Étienne necropolis (Beaune), reveals the existence of two clearly separated zones which are characterized by different funeral and cultural practices: tomb architecture, archaeological material and artificially deformed crania. This seems to provide evidence of two distinct groups. A preliminary morpho-metrical study of four skulls and the examination of several CT scans of three of them, allow us to confirm the presence of artificial antero-posterior cranial deformations.

Data-driven Interactive Multiobjective Optimization : Challenges and a Generic Multi-agent Architecture

2020

In many decision making problems, a decision maker needs computer support in finding a good compromise between multiple conflicting objectives that need to be optimized simultaneously. Interactive multiobjective optimization methods have a lot of potential for solving such problems. However, the growth of complexity in problem formulations and the abundance of data bring new challenges to be addressed by decision makers and method developers. On the other hand, advances in the field of artificial intelligence provide opportunities in this respect. We identify challenges and propose directions of addressing them in interactive multiobjective optimization methods with the help of multiple int…

Próba implementacji techniki rysunku na dowolny temat na grunt praktyki pedagogicznej

2022

Rysunek na dowolny temat jest komunikatem symbolicznym i tak powinien być odczytywany. Służy temu analiza oparta na kryteriach oceny, które są płynne i zależne od intencji badacza. Rozumienie rysunku powinno przebiegać podobnie jak przebiega rozumienie wszystkich wytworów kultury duchowej człowieka. Podstawą rozumienia wytworów kultury jest interpretacja, polegająca na odczytywaniu znaczeń symboli obecnych w tradycji (mity, baśnie) i współczesnej kulturze dziecka (bajki, świat wirtualny, media). Jej celem jest poznanie i (z)rozumienie dziecka. W pracy pedagoga interpretacja rysunku dziecka polega na poszukiwaniu jego sensu poprzez odczytywanie znaczeń symboli występujących we wzajemnych pow…

Multi-Agent Based Energy Management in Microgrids Using MACSimJX

2019

Excessive growth in electricity consumption has been experienced over the past few years due to an increase in population around the world.This tends to increase the use of renewable energy and randomness of the load. So.it is important to improve the traditional methodologies and techniques applied on microgrid to make it more intelligent. In this paper, multi agent system is employed over autonomous microgrid framework to endorse its intelligence. The Multi-Agent system is simulated in Java Agent Development Environment (JADE) environment and matlab toolbox Simulink is used for the implementation of the microgrid model. Further, MACSimJX is used to communicate between the micro grid and a…

Opinion dynamics and stubbornness through mean-field games

2013

This paper provides a mean field game theoretic interpretation of opinion dynamics and stubbornness. The model describes a crowd-seeking homogeneous population of agents, under the influence of one stubborn agent. The game takes on the form of two partial differential equations, the Hamilton-Jacobi-Bellman equation and the Kolmogorov-Fokker-Planck equation for the individual optimal response and the population evolution, respectively. For the game of interest, we establish a mean field equilibrium where all agents reach epsilon-consensus in a neighborhood of the stubborn agent's opinion.

Generating a Located Synthetic Population of Individuals, Households, and Dwellings

2017

Some of the new approaches in urban modeling, such as multi-agent systems (MAS) or activity-based models (ABM), require inputs in the form of disaggregated individual data. But for privacy protection reasons, such data is seldom available at this level. One way to get around this obstacle is to generate a synthetic population. This paper presents a method for generating a population from fully aggregated socio-demographic and geographic data. Based on French examples, this method can be reproduced anywhere in the country providing a relevant linkage between the characteristics of agents and those of urban spaces. The proposed method is subdivided into two steps. First, a population of agent…

Continuous cover forestry is a cost-efficient tool to increase multifunctionality of boreal production forests in Fennoscandia

2017

Earlier research has suggested that the diversification of silvicultural strategies is a cost-efficient tool to ensure multifunctionality in production forests. This study compared the effects of continuous cover forestry and conventional rotation forestry on ecosystem services and biodiversity in boreal forests in Finland. We simulated over 25,000 commercial forest stands for 100 years under continuous cover and rotation forest management. Forests without management were used as a reference. We compared the effects of silvicultural practices over space and time on ecosystem services, biodiversity indicators and multifunctionality. Our results revealed that continuous cover forestry was bet…
