  2. 11. Car(ing) for our environment? : Consumer eco-innovation adoption and curtailment behaviors: The case of the alternative fuel vehicle

    Author : Johan Jansson; Agneta Marell; Annika Nordlund; John Thøgersen; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Diffusion of innovations DOI ; value-belief-norm VBN theory; alternative fuel vehicles AFV ; eco-innovation; early adoption; curtailment behaviors; proenvironmental attitudes; innovation characteristics; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

    Abstract : Determinants influencing consumer eco-innovation adoption and green curtailment behaviors in a travel context are at the center of this thesis. Previous research on green consumer behavior has uncovered that internalized personal attitudinal factors such as values, beliefs, and norms are influential in determining mainly non-consumption and post-purchase behaviors.

  4. 12. Digester modelling for diagnostics and control

    Author : Johan Jansson; Erik Dahlquist; Thore Berntsson; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulp production; diagnostics; simulation; control; Cellulose and paper engineering; Cellulosa- och pappersteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : This thesis will show the possibility for the development and use of an on-line model for application to continuous digesters for pulp production. The model is developed by using a program called Dymola (Dynamic Modeling Laboratory). What makes the Dymola software so well suited is that the program solves equations simultaneously. READ MORE

  5. 13. High performance adaptive finite element methods for turbulent fluid flow

    Author : Niclas Jansson; Johan Hoffman; Sverker Holmgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Abstract : Understanding the mechanics of turbulent fluid flow is of key importance for industry and society as for example in aerodynamics and aero-acoustics. The massive computational cost for resolving all turbulent scales in a realistic problem makes direct numerical simulation of the underlying Navier-Stokes equations impossible. READ MORE

  6. 14. Fire Spalling of Concrete : Theoretical and Experimental Studies

    Author : Robert Jansson; Johan Silfwerbrand; Ulrich Diedrichs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fire spalling of concrete is not a new phenomenon. To some degree there has always been a risk during rapid heating of concrete. Therefore, to a certain degree the effect of fire spalling is included in the bank of data from fire tests and fires on which our understanding of the fire resistance of concrete is based. READ MORE

  7. 15. A New Audiometric Bone Vibrator, Radioear B81, and the Bone Conduction Implant with Emphasis on Magnetic Resonance Imaging

    Author : Karl-Johan Fredén Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image artifact; magnetically induced torque; balanced electromagnetic separation transducer; magnetic resonance imaging.; bone vibrator; bone conduction; retention magnet; demagnetization;

    Abstract : Hearing by air conduction (AC) and bone conduction (BC) are attributed to be the natural ways of stimulating the cochlea. With AC hearing, the cochlea is stimulated by air pressure variations via the ear canal, whereas with BC hearing, sound vibrations are transmitted thru the skull bone to the cochlea. READ MORE
