  1. 21. Transport service triads in supply networks

    Författare :Victor Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; performance; embeddedness; network; supply chain; service; freight; transport; triad; relationship; sustainability;

    Sammanfattning : This doctoral thesis deals with the embeddedness of transport services in supply networks. The exchange of transport services depends on the exchange of goods since exchange of goods generates demand for transport services. LÄS MER

  3. 22. Microfluidic Preparation and Transport of Long DNA using Pillar Arrays

    Författare :Oskar Ström; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; 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; Fysicumarkivet A:2023:Ström;

    Sammanfattning : 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.

  4. 23. Sustainable Freight Transport from an Urban Perspective

    Författare :Sönke Behrends; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable transport; urban freight transport; intermodal transport; rail transport; Sustainability;

    Sammanfattning : The trend of growing road freight transport causes significant negative impacts on the society, economy and environment. A substantial share of the road freight sector’s externalities is imposed on urban areas because cities are the main destination for freight flows either for production, consumption or for transfer to other locations.

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

    Författare :David Göransson; NanoLund: Centre for Nanoscience; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 25. Improving Travel Satisfaction with Public Transport

    Författare :Roberto Fernández Abenoza; Yusak Octavius Susilo; Oded Cats; Lars E. Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Customer Satisfaction; Service Quality; Public Transport; Door-to-door journey; Trip legs; Multimodal trips; User profiles; Market segmentation; Geographical variations; Transportvetenskap; Transport Science;

    Sammanfattning : The existing link between PT travelers’ satisfaction, ridership and loyalty prove the relevance of improving overall trip satisfaction. The thesis present an array of approaches and methodologies aiming at increasing overall satisfaction with PT door-to-door trips while covering important issues that previous research has failed to address.
