Un Intergiciel de Gestion du Contexte basé Multi-Agent pour les Applications d'Intelligence Ambiante

The complexity and magnitude of Ambient Intelligence scenarios imply that attributes such as modeling expressiveness, flexibility of representation and deployment, as well as ease of configuration and development become central features for context management systems.However, existing works in the literature seem to explore these development-oriented attributes at a low degree.Our goal is to create a flexible and well configurable context management middleware, able to respond to different scenarios. To this end, our solution is built on the basis of principles and techniques of the Semantic Web and Multi-Agent Systems.We use the Semantic Web to provide a new context meta-model, allowing for an expressive and extensible modeling of content, meta-properties (e.g. temporal validity, quality parameters) and dependencies (e.g. integrity constraints).In addition, we develop a middleware architecture that relies on Multi-Agent Systems and a service component based design. Each agent of the system encapsulates a functional aspect of the context provisioning processes (acquisition, coordination, distribution, use).We introduce a new way to structure the deployment of agents depending on the multi-dimensionality aspects of the application's context model. Furthermore, we develop declarative policies governing the adaptation behavior of the agents managing the provisioning of context information.Simulations of an intelligent university scenario show that appropriate tooling built around our middleware can provide significant advantages in the engineering of context-aware applications.La complexité et l'ampleur des scénarios de l'Intelligence Ambiante impliquent que des attributs tels que l'expressivité de modelisation, la flexibilité de representation et de deploiement et la facilité de configuration et de developpement deviennent des caracteristiques centrales pour les systèmes de gestion de contexte. Cependant, les ouvrages existants semblent explorer ces attributs orientés-developpement a un faible degré.Notre objectif est de créer un intergiciel de gestion de contexte flexible et bien configurable, capable de répondre aux différents scenarios. A cette fin, notre solution est construite a base de techniques et principes du Web Semantique (WS) et des systèmes multi-agents (SMA).Nous utilisons le WS pour proposer un noveau meta-modèle de contexte, permettant une modelisation expressive et extensible du contenu, des meta-proprietés (e.g. validité temporelle, parametres de qualité) et des dépendances (e.g. les contraintes d'integrité) du contexte.De plus, une architecture a base de SMA et des composants logiciels, ou chaque agent encapsule un aspect fonctionnel du processus de gestion de contexte (acquisition, coordination, diffusion, utilisation) est developpée.Nous introduisons un nouveau moyen de structurer le deploiement d'agents selon les dimensions du modèle de contexte de l'application et nous elaborons des politiques déclaratives gouvernant le comportement d'adaptation du provisionnement contextuel des agents. Des simulations d'un scenario d'université intelligente montrent que un bon outillage construit autour de notre intergiciel peut apporter des avantages significatifs dans la génie des applications sensibles au contexte

Recommendation AI models: case studies

Seminario presentado en EMAI2021, West Bengal, India, 4/4/2021[EN] The targeted consumers can be not only individuals sensitive to environmental and sustainable consumption issues, but also communities, small businesses (e.g., local coffee shop, school, sports club) that share the same concerns as their customers or are just trying to better address their needs. In addition, this tool is designed to assist decision-makers in companies (e.g., supply chain and purchasing managers) as well as policy makers in assessing the overall sustainability of products. Likewise, the tool can provide valuable information to manufacturers who, based on the "sustainable market momentum" gained, could innovate their products and their approach to improving sustainability, thus differentiating themselves from the competitio

AI models for recommendation

Ponencia presentada en EMAI2021, West Bengal, India, 4/4/2021[EN]Today, the industries of all European countries face common challenges: improving resource efficiency, becoming more environmentally friendly, mitigating climate change, improving the digitization in all segments of the value chain and improving transparency and safety, providing consumers with detailed information and ensuring the safety and quality of the final product. Growing concerns about environmental and social issues are pushing the demands of stakeholders (customers, workers, shareholders, consumers, etc.) and the public towards more sustainable processes and products. Sustainability is closely linked to climate change: the introduction of sustainable measures, both by consumers and producers, is inherently a measure against climate change

Seminario presentado en EMAI2021, West Bengal, India, 4/4/2021[EN]Information tools are one of the types of tools available in an effort to change consumers' perceptions, motivations, knowledge and standards. Accordingly, it is increasingly important for consumers to be able to make informed choices about the products they buy, especially in terms of sustainability. Together with the commitment of businesses and organizations to more responsible and sustainable processes and production, the implementation of the European Green Deal and the Sustainable Development Goals is an urgent challenge to all actors in society to contribute to changing the way we meet our needs

Making Ourselves at Home: Representation, Preservation & Interpretation at Canada\u27s House Museums

Historic house museums are a common, if often overlooked, feature of the Canadian heritage landscape. As national historic sites, and community museums, they address cultural, social, historical and political facets of the past. Pursuing the idea of the house/museum hybrid, this study examines the house museum as a distinct museological type. Chapter One defines house museums both in relation and opposition to encyclopedic, folk, decorative and collection museums, period rooms, model and heritage homes and other sites of living history. It reviews architectural, commemorative and preservation histories to outline the conditions that encouraged their development from the West coast (British Columbia) to the East (Nova Scotia). Chapter Two argues that house museums are part of a broader network of home representations. It demonstrates that they are representations of the domestic environments of the past, which are also responsible for generating and preserving photographs, models, floor plans, blueprints, paintings, prints and drawings of private interiors, imagined dwellings and residential architectures. Case studies are used to show that house museums are constructed, saved, explained, validated, funded and marketed through a range of home representations. Chapter Three looks at multisensory exhibits, interactive displays and participative programs at house museums across Canada to highlight the tensions between conservation concerns and the quality of visitor experiences at these sites. It investigates how house museums have reacted to the tenets of a new museology and an Experience Economy, which emphasize participative involvement, active learning and immersive experience, often at the expense of conservation. Chapter Four acknowledges that many historic homes have been refashioned as birthplace museums and shrines for individual legacies. It interrogates the relationship between house museums and their key interpretive figures by examining discourses and histories that position individuals and their iii homes as integrated subjects. Moreover, it contends that house museums structured around a single historical figure tend to be exclusionary, and reductive of complex narratives. As a whole, the thesis considers the topics of representation, preservation and interpretation to remark upon the function and future of house museums in Canada

μGIM - Microgrid intelligent management system based on a multi-agent approach and the active participation of end-users

[ES] Los sistemas de potencia y energía están cambiando su paradigma tradicional, de sistemas centralizados a sistemas descentralizados. La aparición de redes inteligentes permite la integración de recursos energéticos descentralizados y promueve la gestión inclusiva que involucra a los usuarios finales, impulsada por la gestión del lado de la demanda, la energía transactiva y la respuesta a la demanda. Garantizar la escalabilidad y la estabilidad del servicio proporcionado por la red, en este nuevo paradigma de redes inteligentes, es más difícil porque no hay una única sala de operaciones centralizada donde se tomen todas las decisiones. Para implementar con éxito redes inteligentes, es necesario combinar esfuerzos entre la ingeniería eléctrica y la ingeniería informática. La ingeniería eléctrica debe garantizar el correcto funcionamiento físico de las redes inteligentes y de sus componentes, estableciendo las bases para un adecuado monitoreo, control, gestión, y métodos de operación. La ingeniería informática desempeña un papel importante al proporcionar los modelos y herramientas computacionales adecuados para administrar y operar la red inteligente y sus partes constituyentes, representando adecuadamente a todos los diferentes actores involucrados. Estos modelos deben considerar los objetivos individuales y comunes de los actores que proporcionan las bases para garantizar interacciones competitivas y cooperativas capaces de satisfacer a los actores individuales, así como cumplir con los requisitos comunes con respecto a la sostenibilidad técnica, ambiental y económica del Sistema. La naturaleza distribuida de las redes inteligentes permite, incentiva y beneficia enormemente la participación activa de los usuarios finales, desde actores grandes hasta actores más pequeños, como los consumidores residenciales. Uno de los principales problemas en la planificación y operación de redes eléctricas es la variación de la demanda de energía, que a menudo se duplica más que durante las horas pico en comparación con la demanda fuera de pico. Tradicionalmente, esta variación dio como resultado la construcción de plantas de generación de energía y grandes inversiones en líneas de red y subestaciones. El uso masivo de fuentes de energía renovables implica mayor volatilidad en lo relativo a la generación, lo que hace que sea más difícil equilibrar el consumo y la generación. La participación de los actores de la red inteligente, habilitada por la energía transactiva y la respuesta a la demanda, puede proporcionar flexibilidad en desde el punto de vista de la demanda, facilitando la operación del sistema y haciendo frente a la creciente participación de las energías renovables. En el ámbito de las redes inteligentes, es posible construir y operar redes más pequeñas, llamadas microrredes. Esas son redes geográficamente limitadas con gestión y operación local. Pueden verse como áreas geográficas restringidas para las cuales la red eléctrica generalmente opera físicamente conectada a la red principal, pero también puede operar en modo isla, lo que proporciona independencia de la red principal. Esta investigación de doctorado, realizada bajo el Programa de Doctorado en Ingeniería Informática de la Universidad de Salamanca, aborda el estudio y el análisis de la gestión de microrredes, considerando la participación activa de los usuarios finales y la gestión energética de lascarga eléctrica y los recursos energéticos de los usuarios finales. En este trabajo de investigación se ha analizado el uso de conceptos de ingeniería informática, particularmente del campo de la inteligencia artificial, para apoyar la gestión de las microrredes, proponiendo un sistema de gestión inteligente de microrredes (μGIM) basado en un enfoque de múltiples agentes y en la participación activa de usuarios. Esta solución se compone de tres sistemas que combinan hardware y software: el emulador de virtual a realidad (V2R), el enchufe inteligente de conciencia ambiental de Internet de las cosas (EnAPlug), y la computadora de placa única para energía basada en el agente (S4E) para permitir la gestión del lado de la demanda y la energía transactiva. Estos sistemas fueron concebidos, desarrollados y probados para permitir la validación de metodologías de gestión de microrredes, es decir, para la participación de los usuarios finales y para la optimización inteligente de los recursos. Este documento presenta todos los principales modelos y resultados obtenidos durante esta investigación de doctorado, con respecto a análisis de vanguardia, concepción de sistemas, desarrollo de sistemas, resultados de experimentación y descubrimientos principales. Los sistemas se han evaluado en escenarios reales, desde laboratorios hasta sitios piloto. En total, se han publicado veinte artículos científicos, de los cuales nueve se han hecho en revistas especializadas. Esta investigación de doctorado realizó contribuciones a dos proyectos H2020 (DOMINOES y DREAM-GO), dos proyectos ITEA (M2MGrids y SPEAR), tres proyectos portugueses (SIMOCE, NetEffiCity y AVIGAE) y un proyecto con financiación en cascada H2020 (Eco-Rural -IoT)

Sensory urban mapping: a case study of Istiklal Street, Istanbul with the method of 'sensewalking'

The 'sensory' plays a vital role in examining human and world interrelations if often overlooked. This thesis aims to have a new understanding of Istiklal Street, Istanbul, through the area's sensory qualities. The research is ground on a 'phenomenological' approach and intends to move beyond the urban visual experiences by looking into the area's multi-sensory experiences. The practice of 'sensewalking' has been used in research to cope with visually-oriented urban assessments. This investigation, which is structured with a qualitative lens to discover the Street's sensory aspects, would be worthwhile primarily for the fields of architecture, urban sensory design. As we see, the changing socio-cultural structure, economic and political movements, law regulations, innovative transportation and communication activities have resulted in a controversial modification of Istanbul in recent years. On Istiklal Street, Istanbul's culture, entertainment, tourism focus, many buildings were restored, moved, converted, closed, and demolished after the 1990s. All have been significant elements in terms of the qualitative value of this area. Many debates have been put forward by social scientists, urban planners, and architects about Istiklal Street's transformation. Except for the field of academic discussions, the enormous amounts of discourses in social media have shown that the multi-layered socio-cultural and architectural structure of Istiklal Street has been changing dramatically in a controversial way. This thesis supports the idea that while Istiklal Street has changed, the transformation has not been only spatial, socio-cultural, or economic. The research claims that the sensory experiences which have great importance in terms of intangible qualities of this area have begun to lose their distinctive features. Therefore, the research has focused on the individually sensed and assessed sensory qualities on the Street beyond the visual experiences. With the way of 'mapping', collected data of the sensewalking-based fieldworks has been presented. As the primary assessment, the research claims that Istiklal Street's sensory dimensions deserve to be recorded and decoded as expeditiously as possible to observe the sensory reflections of transformations in the area. The research findings showed that Istiklal Street's latest modifications and adjustments had arguably influenced this place's sensory qualities. The result says sensory stimuli of the place are connected, and the sensory elements create a specific sensory ambience. Moreover, the sensory interaction in the place is infected by the physical or spatial changes in the area. This research offers convincing evidence for the argument that the sensory composition of the urban place should not be considered separately from its non-visual characteristics. Istiklal Street's sensory consideration needs to be embedded in further investigations and applications. Increasing awareness about the distinctive sensory qualities and Sensemarks of urban places is worthwhile. The inhabitants' sensory urban experiences provide new insights to comprehend urban places. The research method, ‘sensewalking’, produced an unconventional, novel attitude in the context of qualitative-based urban studies to see the sensory reflections of the physical urban transformations. The research's findings opened creative and productive ways for architecture, urban design, planning, urban ethnography, and intangible heritage studies.
