  2. 1. A pulsed TV holography system for the study of transients in experimental mechanics

    Author : Per Gren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : An all-electronic system for pulsed holographic interferometry called pulsed TV holography is developed. This is a whole-field non-contacting optical measurement method suitable for studies of transient events like wave propagation in solids and fluids. READ MORE

  5. 3. Particle dynamics during biomass devolatilization : Momentum exchange and particle dispersion

    Author : Angel David Garcia Llamas; Kentaro Umeki; Rikard Gebart; Per Gren; Peter Glarborg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; devolatilization; rocketing; PIV; PTV; Energiteknik; Energy Engineering;

    Abstract : Devolatilization is a heat-driven thermochemical process in which a liquid or a solid fuel releases mass in the form of volatile compounds after drying, as a result of the combination of endothermic and exothermic reactions. It differs from pyrolysis in that it does not require an inert atmosphere and that the reactant must be either solid or liquid. READ MORE

  6. 4. Individually tailored internet-based cognitive behavioural therapy for adolescents, young adults and older adults with anxiety

    Author : Kristin Silfvernagel; Gerhard Andersson; Per Carlbring; Malin Gren Landell; Ida Flink; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; internet-based treatment; cognitive behavioural therapy;

    Abstract : Anxiety disorders share the feature of excessive fear, anxiety and related behavioural disturbances. Fear is defined as the emotional response to a real or a perceived imminent threat and anxiety is the anticipation of a future threat. READ MORE

  7. 5. Modelling Life Cycle Cost for Indoor Climate Systems

    Author : Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

    Abstract : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. READ MORE
