  1. 11. Towards efficient vehicle dynamics development From subjective assessments to objective metrics, from physical to virtual testing

    University dissertation from Stockholm : Kungliga tekniska högskolan

    Author : Gaspar Gil Gómez; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering feel; vehicle handling; driver preference; objective metrics; subjective assessments; regression analysis; artificial neural network; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Vehicle dynamics development is strongly based on subjective assessments (SA) of vehicle prototypes, which is expensive and time consuming. Consequently, in the age of computer- aided engineering (CAE), there is a drive towards reducing this dependency on physical test- ing. READ MORE

  2. 12. Studies on the competitiveness of wood - market segmentation and customer need assessments

    University dissertation from Växjö : Växjö University Press

    Author : Ragnar Jonsson; Växjö universitet.; [2005]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; wood; building material; material substitution; end-consumer; floorcovering; customer needs; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Over the last decades, wood has encountered increasing competition from other building materials. Hence, it is relevant to study the underlying factors of material substitution. The market for repair and remodelling (R&R) is growing in importance. READ MORE

  3. 13. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams Model Assessments Based on Tracer Tests

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Jonsson; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; conservative; hyporheic exchange; model; reactive; retention; solute; sorption kinetics; stream transport; temporal moments; tracer experiment; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Sedimentology; sedimentologi;

    Abstract : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

  4. 14. Biogas in Sweden - Opportunities and challenges from a systems perspective

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mikael Lantz; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Policy Instruments; Techno-economic assessments; Environmental assessments;

    Abstract : Popular Abstract in Swedish Biogas, som i huvudsak består av metan och koldioxid produceras när mikroorganismer bryter ned organiskt material utan tillgång till syre, så kallad rötning. I princip kan alla typer av organiskt material användas för att producera biogas men vanligast är till exempel avloppsslam, olika typer av avfall från hushåll och industrier, gödsel, grödor och odlingsrester.

  5. 15. Statistical modeling in international large-scale assessments

    University dissertation from Umeå : Umeå universitet

    Author : Inga Laukaityte; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

    Abstract : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.
