  1. 6. Integrated Cellulosic Wood Aerogel Structures

    Författare :Jonas Garemark; Yuanyuan Li; Lars Berglund; Gustav Nyström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerogel; cellulose; energy harvesting; ionic liquids; nanotechnology; wood; thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Highly porous aerogels based on renewable materials that possess structural functionality are appealing for sustainable energy regulation and harvesting. Achieving structural anisotropy provides advantageous directional diffusion and mechanical strength, however, introduces great engineering challenges, such as complex, costly, and time-consuming processing.

  3. 7. Simulation and optimization of innovative urban transportation systems

    Författare :Jonas Hatzenbühler; Erik Jenelius; Oded Cats; Gyözö Gidofalvi; Joseph Chow; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : The ongoing trends of urbanization and e-commerce continuously challenge the existing urban transportation systems. A steadily growing number of people traveling within urban areas, results in more trips taken with public transportation systems. LÄS MER

  4. 8. Transition Towards Fixed-Line Autonomous Bus Transportation Systems

    Författare :Jonas Hatzenbühler; Erik Jenelius; Oded Cats; Clas Rydergren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Buses; Public Transportation; Network Design; Resource Allocation; Simulation-based multi-objective Optimization; Transportvetenskap; Transport Science;

    Sammanfattning : In the last years the steady development of autonomous driving technology has enabled the deployment of more mature autonomous vehicles. These vehicles have been applied in several pilot projects worldwide, most commonly in the form of small buses. LÄS MER

  5. 9. Extended Jaynes-Cummings Models In Cavity Qed

    Författare :Jonas Larson; Stig Stenholm; Peter L. Knight; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Optics; Optics; Optik;

    Sammanfattning : Due to the improvement within cavity quantum electrodynamics experiments during the last decades, what was former seen as 'toy models' are today realized in laboratories. A controlled isolated coherent evolution of one or a few atoms coupled to a single mode inside a cavity is achievable. LÄS MER

  7. 10. On the Experimental Determination of Damping of Metals and Calculation of Thermal Stresses in Solidifying Shells

    Författare :Jonas Åberg; Hasse Fredriksson; Björn Widell; Michael Vynnycky; Toshihiko Emi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material damping; measurement methods; calorimetric methods; optical strain gauge measurements; hot cracking; stress in solid shells; ALE; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis explores experimentally and theoretically two different aspects of the properties and behaviour of metals: their ability to damp noise and their susceptibility to crack when solidifying. The first part concerns intrinsic material damping, and is motivated by increased demands from society for reductions in noise emissions. LÄS MER
