  1. 16. Development of Methods for Phase System Characterization in Liquid Chromatography

    Författare :Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

    Sammanfattning : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. LÄS MER

    Sammanfattning : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. LÄS MER

  4. 18. Single limb exercises in patients with chronic obstructive pulmonary disease : feasibility, methodology, effects and evidence

    Författare :Andre Nyberg; Karin Wadell; Britta Lindström; Monika Fagevik Olsén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic obstructive pulmonary disease; elastic resistance; exercise capacity; health-related quality of life; randomized controlled design; single limb exercises; systematic review; study protocol;

    Sammanfattning : Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. COPD is a slowly progressive, inflammatory disease in the airways and lungs, caused mainly by smoking. The inflammation leads to a narrowing of the small airways (airway obstruction) and a destruction of tissue in the lungs. LÄS MER

    Författare :Tomas Berling; Institutionen för datavetenskap; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 20. Using soft systems methodology as a methodology for multi-modal systems design

    Författare :Birgitta Bergvall-Kåreborn; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Sammanfattning : The aim of this research is to contribute to the field of systems design by developing intellectual tools that can help designers to conceptualise, create and evaluate different design alternatives. In this work I focus my attention on Soft Systems Methodology. LÄS MER
