  2. 12. Energy efficiency in heritage buildings : Conservation approaches and their impact on energy efficiency measures

    Author : Tomas Örn; Agatino Rizzo; Sofia Lidelöw; Andrea Luciani; Elena Lucchi; Luleå tekniska universitet; []
    Keywords : HUMANITIES; HUMANIORA; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; Energy efficiency heritage buildings; Arkitektur; Architecture;

    Abstract : The impeding climate change challenge urges for a reduction of energy use in the built environment. Buildings account for nearly 40% of the total energy use and about 35% of the greenhouse gas emissions in Europe. READ MORE

  3. 13. Energy efficiency in Swedish SMEs : Exploring barriers, knowledge creation and the role of municipal energy efficiency programs

    Author : Fredrik Backman; Jenny Palm; Patrik Thollander; Max Åhman; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy programs; energy efficiency networks; Community of Practice COPs ; barriers; knowledge creation; Policyprogram; energieffektiviseringsnätverk; Community of Practice COP ; barriärer; skapande av kunskap;

    Abstract : The overall aim of this thesis is to analyze how municipalities support small and medium-sized enterprises (SMEs) in their work to improve their energy efficiency. The purpose of this study is to increase the current understanding of how the methods and tools used by municipalities to assist SMEs in improving their energy efficiency influence the end results in terms of achieved energy efficiency, and how knowledge related to energy efficiency is created within SMEs.

  4. 14. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

    Author : Ilker Erdem; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; design; fixture; assembly; manufacturing; efficiency; flexible; production;

    Abstract : The manufacturing industries have been using flexible production technologies to meet the demand for customisation. As a part of production, fixtures have remained limited to dedicated technologies, even though numerous flexible fixtures have been studied and proposed by both academia and industry. READ MORE

  5. 15. High efficiency power amplifiers for wireless communications

    Author : Hossein Mashad Nemati; Chalmers University of Technology; []
    Keywords : load modulation; GaN; supply modulation; LDMOS; efficiency; Power amplifier; MMIC; mHEMT; transmitter architecture;

    Abstract : This thesis presents state-of-the-art high efficiencyharmonically-tuned power amplifiers (PAs) and investigates thecharacteristics and potentials of such amplifiers in two of the mostpromising efficiency enhancement techniques, dynamic supply and load modulation.In this work, a 10 W LDMOS harmonically-tuned PA with 80% power-added-efficiency (PAE) isrealized at 1 GHz.
