Thermal modeling of an ERS during static charging

Electric road systems (ERS) are designed to transfer power to electric vehicles (EV) while moving, not only for charging the on-board battery, but also for propelling the vehicle and supplying the auxiliary systems. The step from dynamic charging to static charging with a conductive ERS is not large since most of the equipment can be used without modification, yet it brings thermal challenges. Sta

On a hierarchical control strategy for multi-agent formation without reflection

This paper considers a formation shape control problem for point agents in a two-dimensional ambient space, where the control is distributed, is based on achieving desired distances between nominated agent pairs, and avoids the possibility of reflection ambiguities. This has potential applications for large-scale multi-agent systems having simple information exchange structure. One solution to thi

Determination of the real part of the η′ -Nb optical potential

The excitation function and momentum distribution of η′ mesons have been measured in photoproduction off Nb93 in the energy range of 1.2-2.9 GeV. The experiment has been performed with the combined Crystal Barrel and MiniTAPS detector system, using tagged photon beams from the ELSA electron accelerator. Information on the sign and magnitude of the real part of the η′-Nb potential has been extracte

N (1520) 3 /2- helicity amplitudes from an energy-independent multipole analysis based on new polarization data on photoproduction of neutral pions

New data on the polarization observables T, P, and H for the reaction γp→pπ0 are reported. The results are extracted from azimuthal asymmetries when a transversely polarized butanol target and a linearly polarized photon beam are used. The data were taken at the Bonn electron stretcher accelerator ELSA using the CBELSA/TAPS detector. These and earlier data are used to perform a truncated energy-in

Driving forces and obstacles to nuclear cogeneration in Europe : Lessons learnt from Finland

Nuclear power plants generate electricity and a large amount of waste heat which is valuable for cogeneration. District heating (DH) is a suitable technology to decarbonize the European heat sector. By contrast with most of nuclear non-electric applications, nuclear district heating (NDH) has already been implemented in Europe, thus providing us with some valuable empirical insights. This paper in

Policy network creation as a driver of energy-efficient industry

Purpose: This paper studies a Swedish municipality that wants to go beyond its own operations, involving the local industry in saving energy to improve the environment. The paper aims to analyse the experiences and practical implications of using policy networks for implementing energy-efficiency measures in private industrial companies. Design/methodology/approach: The researchers closely followe

Stakeholder participation in municipal energy and climate planning – experiences from Sweden

This article analyses the factors influencing stakeholder participation in municipal energy and climate planning, together with stakeholder experiences of participation in such processes. The article presents findings from a survey of 60 Swedish municipalities and detailed case studies of energy and climate planning in five Swedish municipalities to explore which stakeholders are involved, how and

Understanding energy efficiency in Swedish residential building renovation : A practice theory approach

Examining renovation processes having reduced energy consumption as an explicit goal, this article considers how energy efficiency is made part of renovation processes, focusing on the planning and design phase. Interviews and participant observations of meetings have been conducted. Applying a framework developed in practice theory, we demonstrate the importance of understanding routines, technol

Sustainable energy and climate strategies : Lessons from planning processes in five municipalities

Swedish municipalities have traditionally had significant powers and played a major role in implementing national energy strategies. This paper describes the factors influencing development of municipal climate and energy plans in five Swedish municipalities and assesses the relevance and importance of these factors from theoretical and practical perspectives. The questions raised in the paper are

Management and stakeholder participation in local strategic energy planning - Examples from Sweden

When it comes to improving energy efficiency and environmental sustainability, municipalities are important actors. The Swedish Energy Agency initiated a program called Sustainable Municipalities to support strategic energy activities at the local level. Participating municipalities were mandated to develop local energy and climate strategies. This study gives a general overview of how the 60 part

Characterization of Starch Using Flow Field-Flow Fractionation Techniques

To improve the properties and functionality of starch, it is important to understand the physicochemical and structural characteristics as raw material, after being modified to increase its characteristics and/or during changes due to the processing conditions. For this reason, the objective of the present thesis is to improve the understanding of characteristics and molecular properties like mola

Natural resources and social visions for Greenland’s future

The Arctic is often perceived as the new resource frontier in a resource hungry world. Many actors both inside and outside the region are eager to know what opportunities lie under the ice, and many claim a say in the future development of the Arctic. In Greenland, a national economy based on natural resources will lessen the dependence on the former colonial power Denmark. Many consider this an i

Extending the energy efficiency gap

In order to reach the EU: s 20-20-20 primary energy savings target, energy efficiency needs to increase. Previous research on energy use and energy efficiency has focused mainly on the diffusion of energy efficient technologies. The discrepancy between optimal and actual implementation of energy efficient technologies has been illustrated in numerous articles and is often referred to as the energy

Motives for and barriers to household adoption of small-scale production of electricity : Examples from Sweden

A new electricity-production concept attracted massive media attention in Sweden during 2008 when companies be-gan marketing small-scale photovoltaic panels (PVs) and microwind turbines. The products were launched by their simplicity: the components are so easy to install that anyone can do it. How, then, do households perceive these products? Why would households choose to buy them? What do house

Visualizing energy consumption activities as a tool for making everyday life more sustainable

The need to analyze and understand energy consumption in relation to households' activity patterns is vital for developing policy means that contribute to an energy efficient life and what people would deem as a "good" everyday life. To do this we need to learn more about how energy use is a part of everyday life; this article contributes to that objective. We use the time-geographic diary approac

An interdisciplinary perspective on industrial energy efficiency

This paper combines engineering and social science approaches to enhance our understanding of industrial energy efficiency and broaden our perspective on policy making in Europe. Sustainable development demands new strategies, solutions, and policy-making approaches. Numerous studies of energy efficiency potential state that cost-effective energy efficiency technologies in industry are not always
