A novel model of role of conditioning in attention is presented and evaluated on a Nao humanoid robot. The model implements conditioning and habituation in interaction with a dynamic neural field where different stimuli compete for activation. The model can be seen as a demonstration of how stimulus-selection and action-selection can be combined and illustrates how positive or negative reinforceme

In agriculture, as in industry, have many physically demanding jobs disappeared and the physical stress factors have changed. However, the working days in farms are often long, and it is difficult to hire workers for help as the work conditions are considered to be harsh. The thermal work environment in farms is one of the factors influencing the work conditions. This study aimed to find out the p

This work focuses on the design of SC-LDPC codes for transmission over non-ergodic, block-fading channels. Our main contribution is an algorithm, allowing to start from a (J,K )-regular, uncoupled LDPC ensemble, from which one can recursively build up a protograph-based SC-LDPC ensemble having any target diversity order d. The diversity order is achieved assuming a low-complexity iterative decodin

This thesis concerns involuntary treatment of alcoholism. Clients committed according to the Swedish Act on Care of Addicts in Certain Cases were treated in the same residential treatment setting as voluntarily admitted clients. After informed consent, 104 clients (73 men and 21 women of whom 56 were compulsorily committed and 47 voluntarily admitted) participated in a test-series, including asses

Colorectal cancers are globally ranked as the third most common cancer form in terms of incidence and mortality. Diet has long been considered as one of the main factors affecting population outcome regarding development of cancer in the colon. Numerous epidemiological studies have found links between consumption of dietary fibres and milk and reduced risk of cancers including colon cancer. To be

Light influences man both physiological and experiential and different kinds of light sources may have different impact. In a laboratory study the influence of two kinds of light sources, fluorescent tubes and LED on the experience of the surrounding lighting as well as if there were differences in the biological reactions. 42 healthy subjects took part in the study. Two levels of ambient light we

Popular Abstract in Swedish I centrum för avhandlingen står det fotografiska porträttet. Min utgångspunkt har varit att kombinera olika teorier om kön med intresset för fotografi. Syftet har varit att visa hur fotografiska porträtt under perioden 1850-1910 i olika sociala och kulturella relationer medverkade till att formulera skilda bilder av vad en kvinna var. För att kunna göra det jämför jag f"Visiting Reality: Photography and Gender at the End of the Nineteenth Century" In the centre of the dissertation stands the photographic portrait. My point of departure has been to combine different theories of gender with an interest in photography. The aim has been to show how, during the period of 1850 to 1910, photographic portraits in different social and cultural relations contributed to f

Timber-glass composite I-beams were manufactured and tested in bending to failure. The glass web of the I-beam was adhesively bonded to the timber flanges using three different adhesives: Epoxy, Acrylate and Silicone. For the webs two types of 8 mm thick glass were used: annealed float and heat heat-strengthened glass. Before testing the beams with heat-strengthened glass, the residual-stress prof

LEVANDE ORD är ord som har kraft att förändra. Syftet med boken Levande ord för långtidssjukskrivna är att, likt kyrkans evangeliebok, presentera texter om livsnära ämnen, som även icke religiösa människor kan ta till sig. Teman och texter är valda utifrån den verklighet i vilken många långtidssjukskrivna lever. Texterna är mer psykologiska än teologiska, men där så har varit möjligt överensstämme
