När vi talar om framsteg, tänker vi inte bara på teknik och ökad kunskap. Vi tror att kunskapen automatiskt leder till en bättre framtid. Och visst har tankens frihet givit oss makt. Men vi är inte så fria som vi tror.

Efficient CAD tools are desired to reduce the increasing design efforts when algorithms implemented on ASICs are getting more complicated. For microprogrammed accelerator design, a control unit synthesizer is of great importance since the manual design of a controller for a complicated task requires substantial effort. While a hardware specific implementation results in higher performance or lower

In this paper synthetic aperture radar is analyzed from an inverse scattering perspective. It is shown that the classical point scattering model can be generalized to a dipole scattering model. The dipole scattering model reduces to the point scattering model for small aperture angles. For large aperture angles or multiple illumination apertures the dipole model gives an anisotropic reflectivity su

Nuclear quadrupole resonance (NQR) is a radio frequency (RF) technique, able to distinguish between polymorphic forms of compounds containing quadrupolar nuclei, a requirement fulfilled by many high explosives and narcotics. To alleviate the problems of low signal to noise ratio and strong RF interference in NQR detection, various multi-sensor NQR signal detection algorithms have recently been pro

Popular Abstract in Swedish Många sjöar i Sverige och i andra delar av den norra hemisfären blir allt brunare. Detta beror på att mer färgat organiskt material (humösa ämnen) sköljs ut från den omkring liggande marken och transporteras sen in i sjöarna. I min avhandling har jag undersökt om detta leder till att det blir mörkare i sjöarna, och hur detta i så fall påverkar växtplankton, dvs. små mikWater colour is currently increasing in thousands of lakes in the northern hemisphere due to an increased input of terrestrial dissolved organic carbon (DOC), and more specifically coloured disscolved humic matter (DHM). I studied how water colour affects the light climate in the epilimnion and, as a consequence, phytoplankton biomass, species composition and production in lakes in southern Sweden

Objective: There is a need to identify different rehabilitation needs over time among individuals with stroke in order to implement client-centred rehabilitation interventions after stroke. The objective of this research was to describe changes in some aspects of functioning and to explore the patterns of change in functioning in everyday life during the first year after stroke for elderly patient
