Per Ströms rapport Med storebror i uppfinnarverkstan från stiftelsen Den nya välfärden pekar på övervakningssamhället som ett hot mot demokratin och den enskildes integritet. Men integritetsidealet kanske bör se helt annorlunda ut än vad Ström anser. Det skriver Mikael Sundström, universitetslektor i statsvetenskap vid Lunds universitet.

Development and characterization of electrochemical cantilever sensor for bio/chemical sensing applications

We report the improvements made to our previously developed electrochemical cantilever (EC) sensor, where nanoporous gold material is employed as working electrodes in microcantilever arrays, while combined counter-reference electrodes are integrated on the chip. For a surface stress change of 1mN/m induced on the microcantilever, the cantilever deflects is 7.3 nm at the free end, indicating high

Modelling Subsurface Deformation in High Speed Machining of Inconel 718

Abstract in UndeterminedTraditionally, the development and optimization of the machining process with regards to the sub-surface deformation is done through experimental method which is often expensive and time consume. This paper presents the development of a FE-simulation model to predict the depth of sub-surface deformation induced in the high speed machining of Inconel 718 by use of whisker-re
