1. 1. Mechanical and physical properties of semi-isostatically densified wood

   Författare :Jonas Blomberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Technology; Träteknik;

   Sammanfattning : When wood is densified through semi-isostatical compression in a Quintus- press at pressures up to 140 MPa, the material properties change. The cells are flattened, size is decreased and shape is changed, as a consequence of this the density is increased. Most properties of native woods are strongly correlated to the density. LÄS MER

3. 2. VLF and ULF Waves Associated with Magnetospheric Substorms

   Författare :Andrew Collier; Lars Blomberg; James McKenzie; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space physics; Subtorms; Magnetosphere; VLF waves; ULF waves; Space physics; Rymdfysik;

   Sammanfattning : A magnetospheric substorm is manifested in a variety of phenomena observed both in space and on the ground. Two electromagnetic signatures are the Substorm Chorus Event (SCE) and Pi2 pulsations. The SCE is a Very Low Frequency (VLF) radio phenomenon observed on the ground after the onset of the substorm expansion phase. LÄS MER

4. 3. In-line application of electric fields in capillary separation systems

   Författare :Björn Eriksson; Lars Blomberg; Magnus Andersson; Miroslav Macka; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; capillary separation; conductivity; in-line; electric field assisted liquid chromatography; Analytical chemistry; Analytisk kemi; Kemi; Chemistry;

   Sammanfattning : The magnitude of an electric field possible to apply in a capillary separation system is limited, because a high electric field causes a too high current through the capillary. Application of the electric field in-line will give an increased conductivity in the column, further increasing the risk of too high currents. LÄS MER

5. 4. Automatic speaker verification on site and by telephone: methods, applications and assessment

   Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; Information and language technology; Informations- och språkteknologi;

   Sammanfattning : Speaker verification is the biometric task of authenticating a claimed identity by means of analyzing a spoken sample of the claimant's voice. The present thesis deals with various topics related to automatic speaker verification (ASV) in the context of its commercial applications, characterized by co-operative users, user-friendly interfaces, and requirements for small amounts of enrollment and test data.

7. 5. Inklusion en illusion? : Om delaktighet i samhället för vuxna personer med utvecklingsstörning

   Författare :Barbro Blomberg; Lennart Nygren; Jan Tøssebro; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Categorisation citizenship; durable inequality; everyday life; intellectual disability; participation in society; social exclusion inclusion; Social work; Socialt arbete;

   Sammanfattning : The background to this thesis lies in the great changes that have occurred in the disability field during the last threes decades. The purpose of this thesis is to describe, analyze and try to understand how these changes impact on life conditions for adult persons with mild intellectual disabilities. LÄS MER
