  1. 11. Embedded Measurement Systems

    Författare :Lars Bengtsson; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

    Sammanfattning : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. LÄS MER

  3. 12. Mobility Knowledge Graph and its Application in Public Transport

    Författare :Qi Zhang; Zhenliang Ma; Erik Jenelius; Carlos Lima Azevedo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge graph; Smart card data; Public transport; User-station attention; Relation extraction; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Sammanfattning : Efficient public transport planning, operations, and control rely on a deep understanding of human mobility in urban areas. The availability of extensive and diverse mobility data sources, such as smart card data and GPS data, provides opportunities to quantitatively study individual behavior and collective mobility patterns.

  4. 13. Collaborative, Intelligent, and Adaptive Systems for the Low-Power Internet of Things

    Författare :Valentin Poirot; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Networking; Bluetooth Low Energy; Consensus; Low-Power Wireless Networks; TinyML; IoT; Internet of Things; synchronous transmissions;

    Sammanfattning : With the emergence of the Internet of Things (IoT), more and more devices are getting equipped with communication capabilities, often via wireless radios. Their deployments pave the way for new and mission-critical applications: cars will communicate with nearby vehicles to coordinate at intersections; industrial wireless closed-loop systems will improve operational safety in factories; while swarms of drones will coordinate to plan collision-free trajectories.

  5. 14. Regional Intermodal Transport Systems : Analysis and Case Study in the Stockholm-Mälaren Region

    Författare :Behzad Kordnejad; Bo-Lennart Nelldal; Rickard Bergqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Sammanfattning : The global trend of urbanization is evident and also valid in Sweden and for the Stockholm-Mälaren region, also referred to as the Mälaren valley, a region consisting of metropolitan Stockholm and areas around the lake of Mälaren. In this context, efficient urban freight transportation has emerged as essential for sustainable development of urban areas. LÄS MER

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

    Författare :Andreas Vigren; Svante Mandell; Jan-Eric Nilsson; Nash Nash; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; Transportvetenskap;

    Sammanfattning : 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. LÄS MER
