  1. 1. Performance Quantification of Interarea Oscillation Damping Using HVDC

    Author : Joakim Björk; Karl H. Johansson; Lennart Harnefors; Robin Preece; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission control; interarea oscillations; power oscillation damping; small-signal stability; frequency control; controllability; MIMO control; decoupling control; multivariable interaction; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the transition towards renewable energy, and the deregulation of the electricity market, generation patterns and grid topology are changing. These changes increase the need for transfer capacity. One limiting factor, which sometimes leads to underutilization of the transmission grid, is interarea oscillations. READ MORE

  2. 2. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

    Author : Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. READ MORE

  3. 3. Control or elimination : terms for public health interventions against tungiasis and schistosomiasis haematobium

    Author : Per Nordin; Ingela Krantz; Stig Wall; Andreas Ruppel; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tungiasis; urogenital schistosomiasis; control; elimination; public health; intervention; diagnosis; treatment; neglected tropical diseases; praziquantel; mass treatment; Public health; folkhälsa;

    Abstract : The thesis revolves around diagnosis and treatment of tungiasis (sand flea disease) and schistosomiasis haematobium. The causing parasites, Tunga penetrans and Schistosoma haematobium, both have the ability to penetrate intact skin. READ MORE

  5. 5. In-group bias control

    Author : Öyvind Jörgensen; Nazar Akrami; Martin Bäckström; Øyvind Jørgensen; Fredrik Björklund; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; In-group bias; in-group favoritism; control; stereotypes; prejudice;

    Abstract : This thesis explores in-group bias control. It is well-known that people tend to have extra liking for people they identify themselves with. An extra positive in-group attitude may cause discrimination, even in the absence of any negative attitudes towards the out-group. READ MORE
