  1. 21. Contributions to the Use of Statistical Methods for Improving Continuous Production

    Författare :Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Johan Carlson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Continuous process; Statistical process control; Design of experiments; Process improvements; Simulation tool; Engineering process control; Kvalitetsteknik; Quality Technology Management;

    Sammanfattning : Complexity of production processes, high computing capabilities, and massive datasets characterize today’s manufacturing environments, such as those of continuous andbatch production industries. Continuous production has spread gradually acrossdifferent industries, covering a significant part of today’s production. LÄS MER

    Författare :Jan Alpenberg; Fredrik Karlsson; Olof Arwidi; Stefan Yard; Esbjörn Segelod; Lunds universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; small and medium-sized manufacturing companies; contingency factors; super investments; follow-up investments; complement investments; investment-; structure; planning and process; små och medelstora tillverkande företag; superinvesteringar; uppföljningsinvesteringar; investeringar; struktur; planering och beslut; Business studies; Företagsekonomi; Ekonomistyrning; Ekonomistyrning;

    Sammanfattning : This thesis deals with investment issues in connection to growth and expansion related decision processes in small and medium-sized manufacturing companies. It focuses primarily on the empirical knowledge about the structure of the companies’ investments, the processes involved, and the investment behavior in this type of company. LÄS MER

  5. 24. A Browning process : The case of Dar es Salaam city

    Författare :Othmar Simtali Mng'ong'o; Lars Orrskog; Kjell Nilsson; KTH; []
    Nyckelord :Social sciences; green plant; green structure; browining process; ecological area; sustainable city; living environment; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The study is about how green spaces and structures of Dar es Salaam city, quantitatively and qualitatively, are browning out. It also tries to explore the different reasons behind the browning tendency, and what it means to the function of the city and to the daily form of life of the inhabitants. LÄS MER

  7. 25. Process development for combined pentose and hexose fermentation

    Författare :Fredrik Nielsen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Lignocellulose; Xylose fermentation; Co-fermentation; Process design; Agricultural residues; Saccharomyces cerevisiae;

    Sammanfattning : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.
