  1. 6. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

    Författare :Tomas Öberg; Bo Bergbäck; Bo Wiman; Jaakko Paasivirta; Högskolan i Kalmar; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Sammanfattning : Concern is growing about the environmental and health effects of persistent organic pollutants (POPs), many of which are halogenated aromatic compunds. The research reported in this thesis focuses on factors determining their behaviour and release into the environment. LÄS MER

  3. 7. Advances in time–domain induced polarisation tomography : Data acquisition, processing and modelling

    Författare :Per-Ivar Olsson; Teknisk geologi; []
    Nyckelord :Tomography; Signal–to–noise ratio; Waveform; Duty–Cycle; induced polarisation; Electrical properties;

    Sammanfattning : What would you find below your feet – how do you find out? Perhaps you could look at a geological map, drill, or dig? That could work, but sometimes the maps are not detailed enough, and digging everywhere to find out is impractical. Imagine if you could develop a method that allows you to see straight through the ground, as x–rays through the body! To some extent, such methods already exist; you can for example send electric current into the ground that tells you what lies beneath when it returns. LÄS MER

  4. 8. Development of a 2D Temperature Measurement Technique for Combustion Diagnostics using 2-Line Atomic Fluorescence

    Författare :Johan Engström; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser technology; Elektronik och elektroteknik; Electronics and Electrical technology; PLIF; LIF; temperature measurements; TLAF; Laser diagnostic; combustion; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem;

    Sammanfattning : The present thesis is concerned with the development and application of a novel planar laser-induced fluorescence (PLIF) technique for temperature measurements in a variety of combusting flows. Accurate measurement of temperature is an essential task in combustion diagnostics, since temperature is one of the most fundamental quantities for the characterization of combustion processes.

  5. 9. Simulation of robot paths and heat effects in welding

    Författare :Mikael Ericsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Welding; Automation; robotics; Off-line programming; Robotics; Automatiska system; Production technology; control engineering; Finite Element Analysis; reglerteknik; robotteknik;

    Sammanfattning : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. LÄS MER

  7. 10. Characterization of an Electrical Sensor for Combustion Diagnostics

    Författare :Axel Franke; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

    Sammanfattning : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. LÄS MER
