Tankens frihet och biologins gränser

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.

Controller Synthesis for Hardware Accelerator Design

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

Multi-static synthetic aperture radar and inverse scattering

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

Robust Multi-Sensor Detection of Polymorphic NQR Signals

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
