  4. 7. Water Absorption in Two-Layer Masonry Systems - Properties, profiles and predictions

    Author : Peter Johansson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture-diffusivities; masonry; measuremets; moisture-profiles; Material technology; simulations; sorption-isotherms; Materiallära; materialteknik;

    Abstract : The main impetus for this research was the desire to verify models for determining transient moisture profiles in the capillary range. For the evaluations, transient moisture profiles were both simulated and measured, after which the results of the two methods were compared. READ MORE

  5. 8. On the operation of light-emitting electrochemical cells

    Author : E. Mattias Lindh; Ludvig Edman; Thomas Wågberg; Thomas Lanz; Sebastian Reineke; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Artificial Light; Organic Electronics; Light-emitting Electrochemical Cells; Electrochemical Doping; Thin-film Optical Model; Optical Modes;

    Abstract : We are in the midst of a technological revolution that permeates nearly all human activities; artificial light is one of the most visible contributors in this societal change. If more efficient, green, and versatile light sources can be developed, they might improve the life of millions of people around the world while causing minimal damage to our climate and environment.

  6. 9. Modelling of thin and imperfect interfaces : Tools and preliminary study

    Author : Mathieu Gaborit; Peter Göransson; Olivier Dazel; Émeline Sadoulet-Reboul; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin layers; numerical methods; FEM; poroelastic materials; couches fines; méthodes numériques; MEF; matériaux po- roélastiques; Engineering Mechanics; Teknisk mekanik;

    Abstract : For quite some time, the strive for more efficient acoustic absorbers keepsincreasing, driven by a number of psycho-physiological studies on health re-lated dangers of noise exposure. As the global wealth increases and with itthe global expectation of quieter living and working environments, manifestedin both politics and research, an important market for sound absorbing andnoise control systems develops in all industrialised countries.

  7. 10. Management of condition information from railway punctuality perspectives

    Author : Rikard Granström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Due to the increasing need for transportation and environmental concerns, there is a social and political will to transfer transportation services from roads to rail. The increasing demand for railway transportation services has a significant effect on important stakeholder requirements, such as safety, punctuality, dependability, sustainability and costs.
