  1. 11. Suspended forestry machines for sustainable forestry

    Författare :Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. LÄS MER

  3. 12. Mobile Network Operator Collaboration using Deep Reinforcement Learning

    Författare :Athanasios Karapantelakis; Elena Fersman; Crnkovic Ivica; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Fifth Generation Mobile Networks (5G) are designed to offer connectivity services for new types of applications that not only address the needs of private individuals, but also those of enterprise customers. Network requirements of such applications often transcend the capabilities of a single Mobile Network Operator (MNO). LÄS MER

  4. 13. On Stability and Surge in Turbocharger Compressors

    Författare :Bertrand Kerres; Andreas Cronhjort; Mihai Mihaescu; Jörg Seume; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Radial Compressor; Stability; Surge; Hurst exponent; Fractals; Machine Design; Maskinkonstruktion;

    Sammanfattning : Turbochargers are used on many automotive internal combustion engines to increase power density. The broad operating range of the engine also requires a wide range of the turbocharger compressor. At low mass flows, however, turbo compressor operation becomes unstable and eventually enters surge.

  5. 14. Friction in threaded fasteners : Influence of materials and tooling

    Författare :Mayank Kumar; Sergei Glavatskih; Erik Persson; Ellen Bergseth; Ian Sherrington; Robert Wood; KTH; []
    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; Friction; Coating; Surface topography; Tightening speed; Additive manufacturing; Tightening condition; Assembly tool; Material; Friktion; Ytbehandling; Yttopografi; Åtdragningshastighet; Additiv tillverkning; Åtdragningsförhållanden; Monteringsverktyg; Material; Machine Design; Maskinkonstruktion;

    Sammanfattning : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. LÄS MER

  7. 15. Supporting complete vehicle reliability forecasts

    Författare :Julia Lindén; Ulf Sellgren; Anders Söderberg; Fredrik Elgh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability forecast; interactive function; operating conditions; Machine Design; Maskinkonstruktion;

    Sammanfattning : Reliability is one of the properties that customers of heavy trucks value highest.Dependent on all parts and functions of the vehicle, reliability is a complexproperty, which can normally be measured only towards the end of a developmentproject. At earlier development stages, forecasts can give valuable decision supportfor project planning. LÄS MER
