  2. 1. Increasing Product Quality by Verification and Validation Improvements in an Industrial Setting

    Author : Tomas Berling; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software Verification; Software Engineering; Software Validation; Process Improvement; Software Process Metrics; Factorial Design; Software Inspection; computer technology; Systems engineering; Data- och systemvetenskap;

    Abstract : Large and complex software systems are developed as a tremendous engineering effort. The aim of the development is to satisfy the customer by delivering the right product, with the right quality, and on time. READ MORE

  4. 2. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

    Author : Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; Materials Chemistry; materialkemi;

    Abstract : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. READ MORE

  5. 3. A multivariate approach to QSAR

    Author : Sven Hellberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; beta-adrenergic agents; haloalkanes; halogenated anesthetics; peptides; fractional factorial design; multivariate data analysis; principal components PC ; partial least squares PLS ;

    Abstract : Quantitative structure-activity relationships (OSAR) constitute empirical analogy models connecting chemical structure and biological activity. The analogy approach to QSAR assume that the factors important in the biological system also are contained in chemical model systems.The development of a QSAR can be divided into subproblems:1.

  6. 4. Laboratory Ventilation Systems: An Analysis of the Function and Flow Stability of Different Ductwork Design Alternatives

    Author : Madis Laaniste; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory ventilation; transient flow simulation; fume hood;

    Abstract : One of the prerequisites for high safety in laboratories for chemical and microbiological research is a well-functioning ventilation system. The most typical safety measure in these laboratories is to use a fume hood as a place for activities that can cause dangerous emissions to the room air. READ MORE

  7. 5. Railway Wheelsets: Theory, Experiments and Design Considering Temperatures, Stresses and Deformations as Induced by Braking Loads and Contact Forces

    Author : Mikael Fermér; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Railway wheelset components exposed to braking loads and contact forces have been studied. The work has been performed in close cooperation with the Swedish wheelset manufacturer ABB SURA Traction AB, and it has resulted in one brake disc prototype and two different wheel prototypes.
