An array of vibrating contactors on the fingertip can provide information about virtual objects during active exploration of a virtual environment – for example, information about contact area, edges, corners and surface texture. For the operation of such a device, it is necessary to generate in real time an individually specified drive waveform for each contactor of the stimulator array. To reduc
The conventional view is that Sweden transformed its economy and institutions more slowly than other countries after the structural crisis of the late 1970s, and this is held as an explanation for Sweden’s poor economic growth thereafter. This paper questions that view in several aspects. First, it points out that Sweden has performed comparatively well since the end of the EMS crisis. Second, Swe
This paper reviews an efficient inversion technique for complex media utilizing transient electromagnetic scattering data. The approach to solve the scattering problems (direct and inverse) relies on a wave splitting technique and an invariant imbedding technique. The analysis is illustrated by a numerical example.
Recently a new approach to photoemission, EXAFS and electron scattering has been developed. The correlations between target electrons are separated from the active electron-target electron correlations, and the damping effects are coming out explicitly. The theory uses van Hove diagonal Green's functions and projection operator techniques, not the usual diagram expansions. By omitting from the sta
Föreliggande rapport är resultatet av uppdraget att ur brukarens perspektiv redogöra för den process som påbörjas då en samhällsresurs behöver ianspråktagas. Enkäter om ansökningsprocess och upplevelsen av denna samt omfattningen av resurstilldelning h
This study investigates the manifestation of speaker accountability in connection with knowledge statements in two different kinds of academic discourse. The study focuses on knowledge statements which feature a set of knowledge stating verbs, namely argue, claim, suggest, propose, maintain, assume and believe. A corpus is used as the empirical basis and a general metadiscursive approach primarily
