  2. 1. Cost-effective incentives for local electric utilities and industries in co-operation : modelling of technical measures

    Author : Maria Andersson; Björn Karlsson; Curt Björk; Tomas Kåberger; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency;

    Abstract : In the Swedish electricity system there is a great potential for increasing the cost efficiency of the electricity use. However, today the economic incentives, offered for instance by existing electricity rates, are too weak to improve the use of the system. READ MORE

  5. 3. Cooperation in local electricity markets : modelling of technical measures

    Author : Maria Andersson; Björn Karlsson; Curt Björk; Tomas Larsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency; Shadow prices;

    Abstract : This thesis presents a system analysis for co-operation in local electricity markets including distributors and customers. The purpose of co-operation is to minimise the system cost of local markets by introducing system measures, such as end-use measures and municipal co-generation plants. READ MORE

  6. 4. On Identifying Technical Debt using Bug Reports in Practice

    Author : Lakmal Silva; Michael Unterkalmsteiner; Krzysztof Wnuk; Niklas Lavesson; Davide Taibi; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Technical Debt; Architectural Technical Debt; Documentation Debt; Empirical Software Engineering; Design Science; Programvaruteknik; Software Engineering;

    Abstract : Context: In an era where every industry is impacted by software, it is vital to keep software costs under control for organizations to be competitive. A key factor contributing to software costs is software maintenance where a significant proportion is utilized to deal with different types of technical debt. READ MORE

  7. 5. Numerical study on multi-pantograph railway operation at high speed

    Author : Zhendong Liu; Sebastian Stichel; Jens Nielsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical study; pantograph-catenary system; multi-pantograph operation; dynamic behaviour; high-speed operation; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Abstract : Multi-pantograph operation allows several short electric multiple unit (EMU) trainsets to be coupled or decoupled to adapt to daily or seasonal passenger-flow variation. Although this is a convenient and efficient way to operate rolling stock and use railway infrastructure, pantographs significantly influence each other and even significantly change the dynamic behaviour of the system compared to single-pantograph operation in the same condition.
