  1. 21. Modelling and Appraisal in Congested Transport Networks

    Författare :Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

    Sammanfattning : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

  3. 22. An infrastructure of freedom : Atlanta, race, and the struggle over public transportation in the capitalist city

    Författare :Marcus Mohall; Don Mitchell; David Jansson; Theresa Enright; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public transportation; transit; transit struggles; transportation; planning; mobility; politics of mobility; transportation politics; infrastructure; capitalism; race; USA; US South; Atlanta; Social and Economic Geography; Kulturgeografi;

    Sammanfattning : This thesis provides a multiscalar analysis of the production and struggle over the Metropolitan Atlanta Rapid Transit Authority (MARTA), the main transit system in metro Atlanta. It examines how the actions and visions of the state, capital, and transportation activists intersect to structure how and to what extent transit systems can be organized to realize their distinctive potential to allow urban residents to meet their basic mobility needs.

  4. 23. For every word has its own shadow: Sunsets, Notes From Underground, Waves

    Författare :Lisa Tan; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; affect; becoming; Maurice Blanchot; displacement; dispossession; essay film; experimental video; geological time; liminal; Clarice Lispector; materialism; primordial obscurity; provisional; solitude; Susan Sontag; threshold; transformation; translation; video; video installation; Virginia Woolf;

    Sammanfattning : Liminality permeates this doctoral project's questions: how can an experience of the liminal exist as an artwork? What things and experiences can orient us towards affectivity and states of becoming? Lisa Tan relates such concerns to Clarice Lispector whose writing renders becoming(s) visible. Coupled with Maurice Blanchot and his literary discourse on dispossession and the outside (analogous to becoming), Tan's inquiry is critically engaged inside a moving image practice. LÄS MER

  5. 24. Rail Corrugation Growth on Curves

    Författare :Peter Torstensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; track and wheelset structural flexibility; small radius curves; short-pitch rail corrugation; dynamic vehicle–track interaction; test rig and field measurements; wear;

    Sammanfattning : Short-pitch rail corrugation that may develop on the low (inner) rail on small radius curves causes increased noise and vibration levels on railway networks worldwide. In lack of a generally applicable treatment, track authorities are forced to run expensive rail grinding programs on a regular basis to manage these problems. LÄS MER

  7. 25. Skilda medievärldar : Lokal offentlighet och lokala medier i Stockholm

    Författare :Gunnar Nygren; Lars Nord; Tomas Andersson Odén; Stockholms universitet; []

    Sammanfattning : The main purpose of this thesis is to study mediated political communication in Stockholm, focusing on media content as well as media consumption and the role media play in a democracy. The study is based on content analysis of local and regional media (newspapers, tv and radio) in the greater Stockholm region and on a survey with 2 440 answers from people living in different parts of the region.
