Institutionen för Designvetenskaper på lth presenterar här sitt första forskningsprogram inom området "Äldre och Design". Flera av institutionens forskningsavdelningar har en mångårig, i vissa fall tioårig tradition på området, och nu förs insatserna sa
In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. The advantage of this stroboscopic method compared to conventional time-averaging techniques, is the time-resolution it provides as well as being non-invasiv
Wave propagators are introduced for transient wave propagation in a general one-dimensional medium. The definition of wave propagators is based upon a wave splitting technique. Several properties for the propagators are given and the relations between the method of propagators and the invariant imbedding method and the Green function approach are discussed.
