  1. 1. Efficiency and acceptability of pricing policies and transport investments in distorted economies

    Författare :Jonas Westin; Lars-Göran Mattsson; Jonas Eliasson; Joel Franklin; Kurt Van Dender; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road pricing; transport investment; cost-benefit analysis; tax distortions; transport policies; welfare effects; political economy; acceptability; SRA - Transport; SRA - Transport;

    Sammanfattning : This thesis contains five papers studying the economic efficiency and political acceptability of road pricing policies and transport investments in distorted economies. Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the welfare effect of a road pricing policy or a transport investment.

  3. 2. Optimal Speed and Powertrain Control of a Heavy-Duty Vehicle in Urban Driving

    Författare :Manne Held; Jonas Mårtensson; Jonas Fredriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; optimal control; heavy-duty vehicles; trucks; powertrain control; fuel; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A major challenge in the transportation industry is how to reduce the emissions of greenhouse gases. One way of achieving this in vehicles is to drive more fuel-efficiently. LÄS MER

  4. 3. Senior Managers and Lean- The importance of becoming a practitioner

    Författare :Jonas Renström; Lars Bengtsson; Jörgen Eklund; Camilla Niss; Lars Medbo; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lean; leadership; management; Lean management; senior managers; Lean implementation;

    Sammanfattning : Considered to be one of the most influential paradigms in manufacturing, Lean has developed and expanded beyond the shop floor and manufacturing environment of the auto industry. Lean is considered to be applicable throughout organizations and other industries besides manufacturing. LÄS MER

  5. 4. Migration from plastic food packaging during microwave heating

    Författare :Jonas Alin; Minna Hakkarainen; Sahar Al-Malaika; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; migration; food packaging; microwave; degradation; food simulant; antioxidant;

    Sammanfattning : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. LÄS MER

  7. 5. Toward Realistic Failure Evaluations for Concrete Buttress Dams

    Författare :Jonas Enzell; Anders Ansell; Erik Nordström; Andreas Sjölander; Richard Malm; Leif Lia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; buttress dams; stability analysis; dam failure behavior; physical model tests; FEM; betongdammar; lamelldammar; stabilitetsanalys; dammbrott; fysiska modellförsök; FEM; Betongbyggnad; Concrete Structures;

    Sammanfattning : Concrete dams, complex structures supporting massive loads, have traditionally been assessed using simplified 2D analytical stability analyses based on the rigid body assumption. Previous studies have shown that 3D behavior, such as the interaction between the monoliths and the valley's geology, can greatly impact the load-bearing capacity of gravity dams but remains largely unexplored in buttress dams.
