  1. 1. Systematisk arbetsvärdering : ett lönesättningsinstrument i närbild

    Författare :Thomas Ericsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Job evaluation; wage determination; work of comparable worth; sex discrimination; equal opportunity; woman worker; labour legislation; food industry; local level; case study; model; statistical table;

    Sammanfattning : The subject of the thesis is systematic job evaluation for purposes of local wage determination for blue-collar jobs within the Swedish industry. The method is examined from a general wage-determination as well as from a gender equality perspective. The thesis is based on e.g. LÄS MER

  3. 2. Improving Development of Communication Software in Industrial Control Systems using Simulation

    Författare :Niclas Ericsson; Mats Björkman; Johan Åkerberg; Thomas Lennvall; Per Hurtig; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Sciences; Datavetenskap datalogi ;

    Sammanfattning : In the industrial domain customers expect a product longevity of 10-20 years, with high reliability and availability. Since industrial distributed control systems often are safety critical, aspects such as determinism, low latency and jitter are crucial. LÄS MER

  4. 3. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level

    Författare :Vanja Blazinic; Ellen Moons; Leif Ericsson; Thomas Wågberg; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photovoltaics; polymer solar cell; conjugated polymers; fullerene; photo-oxidation; spectroscopy; Physics; Fysik;

    Sammanfattning : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. LÄS MER

  5. 4. Variance reduction methods for numerical solution of plasma kinetic diffusion

    Författare :Lars Josef Höök; Torbjörn Hellsten; Thomas Johnson; Lars-Göran Ericsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; variance reduction; Monte Carlo; quasi-Monte Carlo; kinetic diffusion; stochastic differential equation;

    Sammanfattning : Performing detailed simulations of plasma kinetic diffusion is a challenging task and currently requires the largest computational facilities in the world. The reason for this is that, the physics in a confined heated plasma occur on a broad range of temporal and spatial scales. LÄS MER

  7. 5. Design approaches for grouting of rock fractures; Theory and practice

    Författare :Jalaleddin Yaghoobi Rafi; Stefan Larsson; Håkan Stille; Thomas Dalmalm; Lars Ericsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; Rock mechanics; Jacking; penetration length; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Sammanfattning : Currently, cement base grout is used widely for sealing of the rock fractures in order to decrease the permeability of rock mass. Grouting procedure is one of the main tasks in cycle of rock excavation. In addition, huge amount of grout should be used during dam construction in order to seal the bedding and embankment walls.
