A new adaptive technique is presented for the increase of the dynamic stiffness of the cutting tool in a lathe by active control of the tool vibration in the cutting speed direction. Due to the statistic properties of tool vibration that are induced by the stochastic behaviour of chip formation process, the controller is based on the filtered-x LMS algorithm which controls an adaptive filter that
All available literature, dealing with optical model calculations, has been reviewed to aid in assessing suitable well parameters and to indicate when the model has been successful in predicting various nuclear data. The material investigated has been indexed according to nuclide, and short abstracts have been prepared to provide a concise summary of the contents and main results. 342 references w
A paradigm shift is emerging in higher education especially regarding how universities should address personalized and collaborative mobile learning. Experiences from three international benchmarking-projects through the European Association of Distance teaching Universities (EADTU), the European Centre for Strategic Management of Universities (ESMU) and the First dual mode benchmarking club on qu
We report on the interfacial behaviour of a series of nonionic diblock copolymers at solid hydrophobic and hydrophilic surfaces/water and silicone oil/water interfaces, studied by ellipsometry. The polymers consist of a hydrophobic C-18 chain linked to a hydrophilic poly(ethylene oxide) (PEO), block varying from 50 to 250 U. The adsorption of these copolymers at low bulk concentrations was found t

Abstract Purpose: This study explored therapists' attitudes to and strategies for developing client-centred approaches in relation to the provision of mobility devices. Method: Four physiotherapists and eight occupational therapists in a Swedish municipality context were interviewed according to a semi-structured interview guide. Data collection and analysis were guided by a qualitative approach,
Met care demands are key aspects in poststroke quality of care. This study aimed to identify baseline predictors and 12-month factors that were associated with perceived unmet rehabilitation needs 1 year poststroke.
There is an increasing interest in new strategies for replacing animal tests in research. The use of cell cultures and integrated electrodes is seen as a promising alternative that could potentially solve this problem. In this work, we present a L-glutamate sensor based on a bienzyme redox hydrogel, capable of detecting the release of this excitatory neurotransmitter from adherently growing cells
Radiative lifetimes of eight odd-parity states of Pt II, in the energy range from 51 408 to 64 388 cm−1, have been measured by means of the time-resolved laser-induced-fluorescence technique. Free, singly ionized platinum ions were obtained in a laser-produced plasma and a tunable laser with 1.5 ns duration pulse was used to selectively excite the Pt+ ions. The comparison of the experimental resul
