    Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER

  4. 24. Time-dependent relaxation of charge and energy in electronic nanosystems

    Detta är en avhandling från Food Engineering, Lund Univeristy

    Författare :Jens Schulenborg; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; heat current; quantum dot; relaxation rate; rate detection; generalization of hermiticity; nonunitary dynamics; open quantum system; Coulomb charging energy; voltage switch; transient response; electronic nanosystem;

    Sammanfattning : The study of the dynamics of strongly confined, interacting open quantum systems has attracted great interest over the past years, due to potential applications in nanoelectronics, metrology as well as quantum information. Most recent experimental and theoretical research in this field has shifted attention towards electronic heat currents, recognizing their potential for practical purposes as well as for tests of fundamental theories, and also aiming to control the inevitable heat dissipation of any dynamically operated electronic device.

  5. 25. Control of vehicle platoons and traffic dynamics catch-up coordination and congestion dissipation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mladen Čičić; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Congestion; Intelligent Transport Systems; Moving Bottlenecks; Platoon Coordination; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array ofnegative effects on the society, from wasted time and productivity to elevated air pollution and increased number of accidents. Classical traffic control methods have long been successfully employed to alleviate congestion, improving the traffic situation of many cities and highways. LÄS MER
