In his licentiate thesis, Calle Sjöström sums up his own and Certec's experience from almost five years' work on haptic interfaces for people with disabilities. The haptic technology tested have great potential for future development, but need refinement
The radiative lifetimes of the metastable a 9DJ (J = 2-5) levels in Eu II have been measured by laser probing of a stored ion beam. The lifetimes of all four J levels are slightly above 1 s. A deviation from the expected energy dependence of the decay rates for electric quadrupole transitions is observed and discussed.

The concept of non-radiating sources is introduced to transmission lines in the time-domain analysis. A method is presented to construct localized voltage and current sources which do not produce any fields outside the source domain. These sources cannot therefore be detected by measurements made outside the source region. The importance of such sources for the uniqueness of the inverse source pro
This paper treats the problem of calculating the macroscopic effective properties of dielectric mixtures where both the inclusions and the background medium can be anisotropic. For this homogenization process, the Maxwell Garnett -type approach is used where the inclusions are assumed to be spherical and embedded in a homogeneous background medium. The anisotropy of the background medium has to be
