    Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

  2. 2. In-situ concrete frameworks in multifamily buildings : Modelling and simulation of construction methods and activities

    Author : Robert Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In Sweden and elsewhere in the world the construction industry has encountered criticism due to its lower productivity gains in comparison to other industries. This is why continual improvement of processes and forms of cooperation are important, as is utilisation of technologies giving greater efficiencies. READ MORE

  3. 3. Use of configuration information in construction projects to ensure high performance of healthcare facilities

    Author : Pia Schönbeck; Anders Ansell; Malin Löfsjögård; Göran Lindahl; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; configuration management; information management; project management; product management; healthcare facilities; Civil and Architectural Engineering; Byggvetenskap; Betongbyggnad; Concrete Structures;

    Abstract : The transfer of information between the different phases of construction projects is limited, which complicates the quality assurance of configurations. Functional requirements on the building configuration are often ambiguous and lack measurable acceptance criteria. READ MORE

  4. 4. Design Iteration Control Framework for Offsite Building Projects

    Author : Martin Haller; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : During the course of the studies this thesis is based upon a designiteration control framework for offsite building projects wasconceptualized. The ultimate goal was to develop a robust tool to assistproject managers to find the optimal balance between maintainingsufficient project-by-project iteration to solve complex designproblems, and avoiding excessive iteration, which unnecessarilycomplicates design and scheduling.

  5. 5. Design approaches for grouting of rock fractures; Theory and practice

    Author : Jalaleddin Yaghoobi Rafi; Stefan Larsson; Håkan Stille; Thomas Dalmalm; Lars Ericsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; Rock mechanics; Jacking; penetration length; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Currently, cement base grout is used widely for sealing of the rock fractures in order to decrease the permeability of rock mass. Grouting procedure is one of the main tasks in cycle of rock excavation. In addition, huge amount of grout should be used during dam construction in order to seal the bedding and embankment walls.
