1. 1. Modeling of Hindered Diffusion in Gels

   Författare :Jan Gutenwik; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective diffusion coefficient; pore size distribution; obstruction; immobilization; modeling; adsorption kinetics; hindered diffusion; simulation program; proteins; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. LÄS MER

5. 4. The Double Obstacle Problem on Metric Spaces

   Författare :Zohra Farnana; Jan Björn; Anders Björn; Juha Kinnunen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metric space; nonlinear; obstacle problem; p-harmonic; potential theory; regularity; stability; MATHEMATICS; MATEMATIK;

   Sammanfattning : During the last decade, potential theory and p-harmonic functions have been developed in the setting of doubling metric measure spaces supporting a p-Poincar´e inequality. This theory unifies, and has applications in several areas of analysis, such as weighted Sobolev spaces, calculus on Riemannian manifolds and Carnot groups, subelliptic differential operators and potential theory on graphs.

7. 5. Usability – Who Cares? : The Introduction of User-Centred Systems Design in Organisations

   Författare :Åsa Cajander; Jan Gulliksen; Inger Boivie; Bodil Jönsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; User-Centred System Design; UCSD; Human-Computer Interaction; HCI; Usability; Perspectives; Sensemaking; Communities of Practice; Action research; Interpretations; Organisational change; Work environment; IT systems development; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

   Sammanfattning : This thesis analyses the difficulties encountered in the promotion of usability, especially in relation to occupation health issues, when developing IT systems in a public authority. It examines what happens when User-Centred Systems Design (UCSD) approaches are introduced to organisations with in-house systems development for their employees. LÄS MER
