Vertebrate eyes share a common ancestry as well as the basic design with a pupil, a retina and a lens. The lens is essential for perceiving the details in the world around us and ensures that a sharp image of the surroundings is focused onto the photoreceptors in the retina. Certain lenses have multifocal properties, in short multifocal lenses acts as filters, matching the wavelengths, or colours,

This paper analyzes communication in a price competition game using the level-$k$ theory of bounded rationality. The level-k analysis predicts prices to be higher with communication than without. Our experimental evidence lends support to the view that communication affects subjects in a way that is compatible with the level-k model, indicating that people lie in order to fool other players that t

Visionen Design för Alla kan berikas genom att inriktningen på genomtänkta statiska lösningar kompletteras med ett design-för-alla-tänkande också för det dynamiska och situationsbundna. Själva görandet i stunden öppnar för nya möjligheter genom att handlingspotentialen och därmed även tillgängligheten bestäms i själva aktiviteten. Beskrivning och makt är nära förknippade med varandra, och en besk

In the present study coping was viewed both as individualistic and collective phenomenon. The aim of the investigation was to study gender and power differences in the use of collective and individualistic coping strategies. Data were collected by means of an Internet based questionnaire sent to 1345 female and male employees both at a managerial and non-managerial level working in a Swedish telec

Xilinx FPGAs offer both Block SelectRAM and distributed RAM for embedded memory. To investigate the impact of utilizing such opportunities, some variations on the hardware implementation of a SNOW 2.0 stream cipher IP core have been designed. We find the ratio of throughput and effective slice usage to be close to 3.5. This allows a flexible trade-off between speed and area consumption, with a thr

Los Angeles Islands är ett konstnärligt forskningsprojekt om arkitektonisk amerikanitet i en svensk region.Los Angeles läggs som ett raster över Malmö. Los Angeles och USA:s västkust har utvecklats till en superprojicering av övriga världens föreställningar om den amerikanska kontinenten.

Energy security is often analysed from a state centric perspective - sometimes as a sub part of national security. That approach disguise the heterogeneity and importance of different actors. This study analyse actor’s roles and capabilities that affect their own and others energy security strategies. The Swedish road transport sector is used as an example. The study also explores how a transition
