  2. 1. Hydrological aspects of the carbon balance in a boreal catchment: A model study

    Author : Alla Yurova; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cartography; pedology; geomorphology; Physical geography; boreal peatland; dissolved organic carbon; ecohydrology; model; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. READ MORE

  4. 2. Model-Based Optimization of Combustion-Engine Control

    Author : Gabriel Turesson; Institutionen för reglerteknik; []
    Keywords : Model Predictive Control MPC ; Partially Premixed Combustion; Pressure Sensor Feedback; Model Based Control; Particle Filter; Multiple Fuel Injections; Gasoline Compression Ignition; Model Predictive Control MPC ; Partially Premixed Combustion PPC ; Low Temperature Combustion; Model Based Control; Multiple Fuel Injections; Pressure Sensor Feedback; Particle Filter; Gasoline Compression Ignition;

    Abstract : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

  5. 3. The relationship between rolling resistance and tyre operating conditions, with a focus on tyre temperature

    Author : Lisa Ydrefors; Annika Stensson Trigell; Jenny Jerrelind; Jurek Ejsmon; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling resistance; tyre temperature; brush model; parametrisation; rolling resistance measurement; drum measurements; operating conditions; tyre; flat track measurements; Rullmotstånd; rullmotståndsmätning; däcktemperatur; driftsförhållanden; trummätning; borstmodellen; parametrisering; däck; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Efforts to reduce greenhouse gas emissions from today’s increasing number of cars and trucks, are crucial in counteracting global warming. These efforts include the intent to reduce the effects of the resistive forces acting on the vehicle. Rolling resistance is one of these forces. READ MORE

  6. 4. Multiple categorization in hiring : The stereotype content model perspective

    Author : Andrea Strinić; Jens Agerström; Magnus Carlsson; Eva Derous; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; warmth; competence; stereotype content model; multiple group membership; intersectionality; hiring; Psychology; Psykologi;

    Abstract : Hiring discrimination research has predominantly focused on labor market outcomes based on one or two group memberships, most commonly ethnicity and gender. The main aim of the doctoral dissertation is to explore warmth and competence perceptions associated with multiple demographic group membership and how they may affect evaluations and behavior in a workplace and hiring context.

  7. 5. Operating cycle representations for road vehicles

    Author : Pär Pettersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Abstract : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. READ MORE
