  1. 21. Topics in Machining with Industrial Robots and Optimal Control of Vehicles

    Författare :Björn Olofsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Two main topics are considered in this thesis: Machining with industrial robots and optimal control of road-vehicles in critical maneuvers. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. LÄS MER

  3. 22. 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

  4. 23. Water and sediment quality of urban water bodies in cold climates

    Författare :Ralf Rentz; Stefan Karlsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The aim of this study was to investigate and quantify pollution impact on urban waterbodies in cold climates and to find out which complex processes and influencing factors causetrapping or spread of pollutants. In order to do that water, sediment and porewater samplesfrom bays and stormwater ditches in Luleå, northern Sweden, and from an artificialstormwater pond in Sollentuna, south-central Sweden, were analysed for LOI, trace metalsand PAHs.

  5. 24. Fish bile in environmental analysis

    Författare :Margaretha Adolfsson-Erici; Michael McLachlan; Lillemor Asplund; Freek Ariese; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish bile estrogenic triclosan rubber additives pulp and paper; Environmental chemistry; Miljökemi;

    Sammanfattning : This work explores the usefulness of fish bile analysis in combination with biomarkers for identifying and evaluating new environmental contaminants in the aquatic environment. It illustrates how bile analysis can be used together with biomarkers to assess the causes of estrogenic effects, to identify chemicals in the aquatic environment that are taken up by fish, and to monitor environmental exposure.

  7. 25. On Noise Generation and Dynamic Transmission Error of Gears

    Författare :Mats Henriksson; Leping Feng; Reader Andy Moorhouse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Sammanfattning : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.
