  2. 1. Aerosol Measurements as Applied for Exposure Characterization

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Abstract : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. READ MORE

  4. 2. Railroading and Labor Migration : Class and Ethnicity in Expanding Capitalism in Northern Minnesote, the 1880s to the mid 1920s

    Author : Jimmy Engren; Lars Olsson; Leslie Page Moch; Växjö universitet; []
    Keywords : HUMANIORA; HUMANITIES; Labor Migration; Immigration History; Swedish-America; Svensk-Amerika; Labor History; Minnesota; Welfare Capitalism; Hegemony; Capitalism; ethnic history; railroad; Socialism; community study; ethnic division of labor; Swedish workers; Swedish immigrants; political economy; Anglo-American; immigrant radicalism; History; Historia; Historia; History;

    Abstract : In the 1880s, capitalism as a social and economic system integrated new geographic areas of the American continent. The construction of the Duluth & Iron Range Railroad (D&IR), financed by a group of Philadelphia investors led by Charlemagne Tower and later owned by the US Steel was part of this emerging political economy based on the exploitation of human and material resources.

  5. 3. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Abstract : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. READ MORE

  6. 4. Improving Timetable Robustness and Punctuality of Railway Traffic : A Combined Simulation-Optimization Approach for Nonperiodic Timetabling on Double-Track Lines

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Rob Goverde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timetabling; Train scheduling; Delay prediction; Punctuality; Railroad; Robustness; Transportsystem; Transport Systems;

    Abstract : To evaluate the robustness of a timetable against minor delays, it can be simulated. A natural question following a simulation is how the results can be used to improve the timetable, which has received limited attention in the literature. READ MORE
