A decentralized load control architecture for smart energy consumption in small islands
2020
Abstract In this paper we propose the adoption of Overgrid, a new decentralized load control architecture, for balancing the energy production variations introduced with the adoption of renewable sources, facilitating and improving the smart energy retrofit. The system is presented and applied for managing the aggregated daily load profile of a community of domestic end-users in the island of Lampedusa, Italy, exploiting the load profiles gathered in a real measurement campaign. The Overgrid Demand Response (DR) architecture is used for managing the residential flexible loads, estimating the aggregated power demand without any centralized server and creating a virtual “community” of smart b…
Non-equilibrium Markov state modeling of periodically driven biomolecules
2019
Molecular dynamics simulations allow to study the structure and dynamics of single biomolecules in microscopic detail. However, many processes occur on time scales beyond the reach of fully atomistic simulations and require coarse-grained multiscale models. While systematic approaches to construct such models have become available, these typically rely on microscopic dynamics that obey detailed balance. In vivo, however, biomolecules are constantly driven away from equilibrium in order to perform specific functions and thus break detailed balance. Here we introduce a method to construct Markov state models for systems that are driven through periodically changing one (or several) external p…
A stepwise power tariff model with game theory based on Monte-Carlo simulation and its applications for household, agricultural, commercial and indus…
2019
Abstract The concept of game theory has been adapted in the regulation of retail electricity market within the constraints of stepwise power tariff (SPT) for economic energy consumption. The objective is to increase the penetration level of renewable energy sources (RES) and electric vehicles with implementation of Bayesian game model for categorized (i.e. household, agricultural, commercial & industrial) consumers. Bayesian game model is based on degree of information shared by consumers due to their selfish nature. The main goal is to create an algorithm using constraints RES, storage through electric vehicles, electric wiring, number of consumer, efficient equipment, social status of fam…
Quand les enseignants claquent la porte
2021
International audience; Les démissions de professeurs des écoles, bien que statistiquement limitées, sont un révélateur de la dégradation des conditions de travail des enseignants dans un contexte d’austérité budgétaire, sans que cette question se limite au thème de la revalorisation des salaires.
Relations entre le système de consommation et les comportements en magasin : une approche par la valeur : application au vêtement
2011
Within the course of the theory of cultural consumption (CCT), this research aims to enlighten on the relationship between the consumer to hir or her system of consumption. The first part, qualitative, attempts to describe the nature of the relationship between the consumer and his or her system (the wardrobe in our case) through an anthropological study and a semiotic study. The data was collected by way of observation (video and audio taped) during usage experiences. The second part, quantitative, measures separately the sedimentation of value linked to usage and shopping experiences. Applied to the clothing market, results show the value of the organisational and systemic concerns (which…
CONCEPTUAL MODEL IN INTEGRATED MARKETING COMMUNICATION
2018
Integrated marketing communications are developing, with IMC approaches to communication with consumers seeing further enhancements in the scientific literature. However, in order to reach the marketing targets, a variety of IMC tools may be used in combination when implementing marketing activities. Despite each IMC tool in itself being highly distinctive, they all depend on each other in the creation of product consumption value and the enhancement of economic, communicational and social benefits. Purpose of the paper: The goal of the research is to assess the integrated marketing communications used in the marketing strategy of Latvian food retail chains. Methodology/methods: The followi…
Barriers to Responsible Consumption in e-Commerce : Evidence from Fashion Shoppers
2021
This qualitative study investigates the barriers to responsible consumption in e-commerce from the online shoppers’ viewpoint. The purpose of the study is to increase our understanding of what prevents young adults from making responsible purchases in online stores in the context of fashion retail. The data were collected by interviewing ten Finnish fashion shoppers aged 23-27 years. The findings show that responsible consumption is perceived as complex and challenging. The study identified barriers related to online stores and consumers themselves. Online store implementation (product availability, information and transparency, and pricing) is vital in facilitating online shoppers’ respons…
Crise économique et grande distribution : ressenti des managers et solutions managériales
2016
Mass retail, since the postwar boom, has developed a mass distribution suitable for mass production flow. However, with the insecurity and impoverishment of consumers, this business model evolves. Some individuals, disaffiliated, are no longer financially able to get their supplies in major outlets and overall, French have changed their buying behavior. This article aims to analyze, through a qualitative study, how the crisis is perceived by department managers and managerial solutions tracks that could be implemented in a crisis context. The originality of this research lies in the chosen angle, that of department managers' perception since they are in front line to see one of the conseque…
Risk Management for Sustainable Sovereign Debt Financing
2021
We model sovereign debt sustainability with optimal financing decisions under macroeconomic, financial, and fiscal uncertainty, with endogenous risk and term premia. Using a coherent risk measure we trade-off debt stock and flow risks subject to sustainability constraints. We optimize static and dynamic financing strategies and demonstrate economically significant savings from optimal financing compared with simple rules and consols, and find that optimizing the trade-offs can be critical for sustainability. The model quantifies minimum refinancing risk and maximum rate of debt reduction that a sovereign can achieve given its economic fundamentals, and an extension identifies optimal timing…
