1. 1. Impact of drying and heat treatment on physical properties and durability of solid wood

   Författare :Margot Sehlstedt-Persson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

   Sammanfattning : During drying and heat treatment, wood is exposed to a hygrothermal process during which wood properties are chemically and physically affected, resulting in responses on a microscopic as well as on a macroscopic level. The main objective of this thesis is to build knowledge on the interaction between the wood material properties and the drying and heat treatment process in terms of material responses. LÄS MER

3. 2. Persons with functional difficulties as resources in ICT design processes

   Författare :Hans Persson; Yngve Sundblad; Ingemar Wedman; Bodil Jönsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; “Design for all”; functional difficulties; usability; useworthiness; accessibility; design methodology; “Design for all”; funktionssvårigheter; användbarhet; användvärdhet; tillgänglighet; designmetodik.; Computational linguistics; Datorlingvistik;

   Sammanfattning : Denna avhandling har sin grund i mina erfarenheter av att arbete med människor som har funktionsnedsättningar. Vanligtvis är denna grupp den sista en producent ser som sina kunder. Det är ganska vanligt att producenter gör olika produkter(produkter och tjänster) för personer med funktionsnedsättningar och en för andra. LÄS MER

4. 3. Tilting trains : Technology, benefits and motion sickness

   Författare :Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

   Sammanfattning : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. LÄS MER

5. 4. Embedding Theorems for Mixed Norm Spaces and Applications

   Författare :Robert Algervik; Viktor Kolyada; Lars-Erik Persson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed norms; embeddings; rearrangements; anisotropic fractional Sobolev spaces; anisotropic Besov spaces; mixade normer; inbäddningar; omarrangeringar; anisotropa fractionära Sobolev rum; anisotropa Besov rum; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

   Sammanfattning : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. The work in this direction originates in a paper due to Gagliardo (1958), and was continued by Fournier (1988) and by Kolyada (2005). We consider fully anisotropic mixed norm spaces. LÄS MER
