  2. 1. Competition in Public Transport : Essays on competitive tendering and open-access competition in Sweden

    Author : Andreas Vigren; Svante Mandell; Jan-Eric Nilsson; Nash Nash; Statens väg- och transportforskningsinstitut; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Public transport; Contract; Tender; Bus; Economic efficiency; Competition; Location; Transport operator; Depot transp ; Impact study; Railway; Line transp ; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Public Transport; Tendering; Procurement; Cost efficient; Open access competition; Transportvetenskap; Transport Science;

    Abstract : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. READ MORE

  4. 2. Microfluidic Preparation and Transport of Long DNA using Pillar Arrays

    Author : Oskar Ström; NanoLund: Center for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; Microfluidics; Deterministic Lateral Displacement; DNA Separation; Elastic Turbulence; Micro-pillar arrays; DNA Sample Preparation; Lab-on-a chip; elastic waves; Sample Preparation; DNA Isolation; bumper array;

    Abstract : This thesis presents a set of microfluidic tools and experimental studies for preparing (> 20 kbp) for genetic analysisas well as the transport of high-concentration, long-DNA solutions in pillar arrays.Long-DNA sample preparation with conventional gel-based techniques is slow (tens of hours to days) and laborious.

  5. 3. Strain and Charge Transport in InAsP-InP and InP-InAs Core-Shell Nanowires

    Author : David Göransson; NanoLund: Center for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; InAsP-InP core-shell nanowire; InP-InAs core-shell nanowire; strain; XRD; charge transport; Coulomb blockade; Josephson junction; Fysicumarkivet A:2019:Göransson;

    Abstract : The mechanical, optical, and electrical properties of III-V semiconductor heterostructures are investigated in thisthesis. The semiconductor materials are grown by metal-organic vapor phase epitaxy, yielding wire shaped crystals(nanowires) having a length of ~ 1 μm and diameter of ~ 100 nm. READ MORE

  6. 4. Charge transport in III-V narrow bandgap semiconductor nanowires

    Author : Bekmurat Dalelkhan; NanoLund: Center for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; InAs; InSb; InP-InAs; narrow bandgap; spin-orbit interaction; quantum dots; Nanowires; Fysicumarkivet A:2019:Dalelkhan;

    Abstract : This thesis describes charge transport in III-V narrow bandgap semiconductor nanowires. We are particularly interested in quantum transport in InSb, InAs and InP-InAs core-shell nanowires. According to the type of transport mechanism dominating in the devices, this thesis can be divided into four parts. READ MORE

  7. 5. Making Equity in Public Transport Count

    Author : Isak Rubensson; Yusak Susilo; Oded Cats; Karst Geurs; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Subsidies; Fare-schemes; Accessibility; Crowding; transport justice; Equity; Distribution; Gini index; Lorenz curves; Customer satisfaction; Service quality; Preferences; Reliability; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

    Abstract : Political and public focus on equity and justice outcomes of public policies is on the rise all over the world. Equity is both philosophically motivated and often decreed by law and in planning directives to be monitored when policies are changed, however oftentimes these equity assessments are vague, qualitative and carries low weight in policy decision processes.
