作者： stephanie Teufel University of Fribourg Switzerland

Since decades, the global electricity demand shows only one direction： a considerable constant increase every year. But the unlimited growth in energy consumption is discussed increasingly critical, not only primarily in terms of limitations but also in terms of more efficient, more intelligent, and more sustainable usage of energy. Energy-efficient technologies （EET） and renewable energy technologies are already in a competitive position in different markets, and they are also actively embedded in scientific research. Meanwhile,

Prosumer Cooperation Behavior:Implications for Prosumer Community Design

引用

Journal of Electronic Science and Technology 2016年第4期14卷 298-310页

作者： Yves Hertig stephanie Teufel International Institute of Management in Technology University of Fribourg1700 FribourgSwitzerland

The decentralization of the energy sector＇s infrastructure is commonly understood as an important step towards an efficient and sustainable energy system. However, technical measures only have a limited impact on the systems goals. The decentralization of decision-making, the empowerment of households and the occurrence of prosumer communities require more human-centric approaches to meet future challenges; the application of the subsidiarity principle and decentralization seems inevitable but also unclear in its implementation in an energy system, the cooperation behavior of community members gains in importance and the design of prosumer communities must overcome economic problems. This article emphasizes the human-centered challenges which go along with prosumer communities. We apply economic principles to reveal major problems which go with the shifts in energy-related decision-making towards prosumers and integrate behavioral science for prosumer community design. We highlight the importance of energy as an interpersonal construct; a view on energy which will gain in importance within a prosumer communities shaped network.

NUMERICAL RECONSTRUCTION OF SMALL PERTURBATIONS IN THE ELECTROMAGNETIC COEFFICIENTS OF A DIELECTRIC MATERIAL

引用

Journal of Computational Mathematics 2014年第1期32卷 21-38页

作者： Marion Darbas stephanie Lohrengel LAMFA UMR CNRS 7252 - Universitd de Picardie Jules Verne Amiens France LMR EA 4535 - Universitd de Reims Champagne-Ardenne Reims France

The aim of this paper is to solve numerically the inverse problem of reconstructing small amplitude perturbations in the magnetic permeability of a dielectric material from partial or total dynamic boundary measurements. Our numerical algorithm is based on the resolution of the time-dependent Maxwell equations, an exact controllability method and Fourier inversion for localizing the perturbations. Two-dimensional numerical experiments illustrate the performance of the reconstruction method for different configurations even in the case of limited-view data.

It is no secret--the world as it is today only runs with energy; and it is also no secret that the world is faced with steadily increasing energy demands. The reduction of dependence on fossil fuels is a global goal. To achieve this goal three paths have to be considered： First, the substitution of fossil fuels with renewable energy; secondly, the increase in energy efficiency and the expansion of opportunities for energy storage; and thirdly, to find solutions to the associated socio-economic challenges.

Crowd Energy Management: New Paradigm for Electricity Market

引用

Journal of Electronic Science and Technology 2015年第3期13卷 195-205页

作者： Mario Gstrein stephanie Teufel the International Institute of Management in Technology University of Fribourg

The traditionally centralized approach of electricity networks is progressively undergoing a shift towards a decentralized, distributed structure. The local and crowd-based principle is transforming the existing supply chain and related activities into a value network （VN）. Previous researches on crowd value network concepts focus on the activities of infrastructure and load management and neglect activities that generate collaboration. Collaboration with and within crowds particularly demands a different mindset and management of sharing values, information, benefit, and risks. Furthermore, these concepts must integrate technical, processual, and social aspects. Thus, this article proposes a holistic framework of electricity VN management for crowd energy. It redefines VN activities for infrastructure and load management while appending VN activities for social electricity handling. Additionally, the framework illustrates the interactions among these three elements and concludes with an adaption cycle for the crowd value network.

Mental health facility codesign: A new research method for integrating the service user voice in design processes using virtual reality

引用

General Psychiatry 2019年第3期32卷 146-151页

作者： stephanie Liddicoat School of Design Faculty of Health Arts and Design Swinburne University of Techn ology Melbourne Victoria Australia Faculty of Architecture Building and Planning The University of Melbourne Melbourne Victoria Australia

Background Within healthcare environments, the emerging field of evidence-based design (EBD) explores the links between wellbeing and good design practice of the built environment. Aim By optimising both design processes and design outcomes, knowledge produced wrthin this field seeks to improve staff performance, augment patient healing and enhance service outcomes and experiences. Methods In a prior study by the author, a mental health service building design was developed which integrated feedback from mental health service users relative to what aspects of the built environments of their care would enhance their service outcomes and experiences, encourage them to avail themselves of services and/or engage in therapy, and those that would reduce their willingness to avail themselves of services. Results The research project protocol detailed here is the final testing stage of this body of work, where service users are invited to evaluate the final building design, experienced through virtual reality. This study addresses a gap in the literature, and aims to advance the field of EBD, and codesign with mental health service users, using virtual reality. Conclusions This research method details the aims, study design, methods and limitations of the study, with recommendations for future researchers.
