  1. 6. Applying quantum approximate optimization to the heterogeneous vehicle routing problem

    Författare :David Fitzek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; variational quantum algorithm; Quantum computing; quantum approximate optimization algorithm; vehicle routing;

    Sammanfattning : Quantum computing offers new heuristics for combinatorial problems. With small- and intermediate-scale quantum devices becoming available, it is possible to implement and test these heuristics on small-size problems. LÄS MER

  3. 7. Towards a Secure and Resilient Vehicle Design: Methodologies, Principles and Guidelines

    Författare :Kim Strandberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle Security; Vehicle Software Updates; Vehicle Resilience; Vehicle Attacks;

    Sammanfattning : The advent of autonomous and connected vehicles has brought new cyber security challenges to the automotive industry. It requires vehicles to be designed to remain dependable in the occurrence of cyber-attacks. LÄS MER

  4. 8. Towards efficient vehicle dynamics development : From subjective assessments to objective metrics, from physical to virtual testing

    Författare :Gaspar Gil Gómez; Mikael Nybacka; Lars Drugge; Egbert Bakker; Peter Pfeffer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering feel; vehicle handling; driver preference; objective metrics; subjective assessments; regression analysis; artificial neural network; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Vehicle dynamics development is strongly based on subjective assessments (SA) of vehicle prototypes, which is expensive and time consuming. Consequently, in the age of computer- aided engineering (CAE), there is a drive towards reducing this dependency on physical test- ing. LÄS MER

  5. 9. Distributed vehicle testing : dynamic simulation for automotive winter testing

    Författare :Mikael Nybacka; Luleå University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, rather than provide parts similar to their competitors and rely on one or two automakers, successful automotive component suppliers focus heavily on innovation and collaboration with several manufacturers in a global market. In this thesis, an as-is scenario for automotive winter testing is presented. LÄS MER

  7. 10. Onboard condition monitoring of vehicle-track dynamic interaction using machine learning : Enabling the railway industry’s digital transformation

    Författare :Rohan Kulkarni; Mats Berg; Ulf Carlsson; Alireza Qazizadeh; Sebastian Stichel; Jordi Viñolas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active preventive maintenance; intelligent fault diagnosis; anomaly detection; vehicle fleet; track irregularities; vehicle hunting; wheel-rail interface.; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The railway sector’s reliability, availability, maintainability, and safety (RAMS) can significantly improve by adopting condition based maintenance (CBM). In the CBM regime, maintenance decisions are driven by condition monitoring (CM) of the asset. LÄS MER
