  1. 1. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Författare :Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. LÄS MER

  3. 2. Project Management - Multidimensional Leadership

    Författare :Susanne Ollila; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; situational approach; model of reflection; multidimensional leadership; product development project management; leadership behaviour;

    Sammanfattning : Project management is increasingly becoming a complex role that more and more people within industry need to master. Today, project organising is used to perform tasks and solve problems of almost any magnitude, complexity, and direction. In many organisations, a significant part of the daily work is conducted by means of projects. LÄS MER

  4. 3. Adaptive Multidimensional Filtering

    Författare :Leif Haglund; Gösta Granlund; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis contains a presentation and an analysis of adaptive filtering strategies for multidimensional data. The size, shape and orientation of the flter are signal controlled and thus adapted locally to each neighbourhood according to a predefined model. LÄS MER

  5. 4. Effects of loading mechanisms and texture on ore breakage : A multidimensional study

    Författare :Parisa Semsari Parapari; Magnus Evertsson; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Breakage mechanism; Loading mechanism; Ore texture; Liberation; Comminution; Mineral Processing; Mineralteknik;

    Sammanfattning :  In comminution machines, the product properties (particle size distribution, mineral liberation characteristics) and process consumables (energy for size reduction, wear) are affected by various parameters. On the one hand, understanding and optimizing these parameters can provide an energy efficient process and a specified product. LÄS MER

  7. 5. On Amoebas and Multidimensional Residues

    Författare :Johannes Lundqvist; Mats Andersson; Martín Sombra; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amoeba; multidimensional residue; duality principle; effective; uniform; Artin-Rees; Ronkin function; matematik; Mathematics;

    Sammanfattning : This thesis consists of four papers and an introduction. In Paper I we calculate the second order derivatives of the Ronkin function of an affine polynomial in three variables. This gives an expression for the real Monge-Ampére measure associated to the hyperplane amoeba. LÄS MER
