Laser control of atoms and molecules

Rather different problems can be lumped together under the general term 'laser control of atoms and molecules'. They include the laser selection of atomic and molecular velocities for the purpose of Doppler-free spectroscopy, laser control of the position and velocity of atoms (i.e. laser trapping and cooling of atoms), and laser control of atomic and molecular processes (ionization, dissociation)

To Boldly Go Where No Man has Gone Before: Seeking Gaia's Astrometric Solution with AGIS

Gaia is ESA's ambitious space astrometry mission with a foreseen launch date in late 2011. Its main objective is to perform a stellar census of the 1,000 million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec (μas) level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - th

WozARd: a wizard of oz tool for mobile AR

Wizard of Oz methodology is useful when conducting user studies of a system that is in early development. It is essential to be able to simulate part of the system and to collect feedback from potential users. Using a human to act as the system is one way to do this. The Wizard of Oz tool presented here is called WozARd and it aims at offering a set of tools that help the test leader control the

Allmänmedicin

I Norge har den redan blivit en klassiker i två upplagor, 1997 och 2003. Nu kommer den på svenska. Den svenska redaktionen, hämtad från samtliga allmänmedicinska avdelningar inom de medicinska fakulteterna, har under ledning av Birgitta Hovelius bearbetat de inte mindre än 74 författarnas insatser. Resultatet är ett uppslagsverk som saknar motstycke. De 883 sidorna ger bredd, omfattning och en u

What is worse: Decreased spatial resolution or increased noise?

Purpose: To investigate the relative importance of spatial resolution and noise on the image quality of clinical radiographs. Methods: The spatial resolution and noise of fifteen digitised lumbar spine radiographs were altered with image processing. Three different MTF curves and three different Wiener spectra were combined into seven different combinations of spatial resolution and noise. These s
