We have studied the application of an independent component analysis (ICA) approach to the identification and possible removal of artifacts from a magnetoencephalographic (MEG) recording. This statistical technique separates components according to the kurtosis of their amplitude distributions over time, thus distinguishing between strictly periodical signals, and regularly and irregularly occu...

NMR artifact purging: Modern NMR experiments depend on efficient coherence transfer pathways for their sensitivity and on suppression of undesired pathways leading to artifacts for their spectral clarity. A novel robust adiabatic element suppresses hard-to-get-at artifacts (see picture).

Based on a study of a three-day workshop between users and developers, we show how artifacts like computer prototypes can be used to trigger productive discussions. We demonstrate how clashes between contextualized artifacts and the practitioners' (users) conceptions and experiences of their work practices trigger new understandings of current practice as well as possible futures. In this way, ...

In this paper we are outlining two ways of conceptualizing the interplay of 1. technology designers/contributors, 2. the artifacts they design and 3. the communities in which they act. A research and development process was conducted on the basis of the notion of objectification of purposes in artifacts – and their appropriation. The outcomes of the research and development process make it more...

Privacy is a complex social process that will persist in one form or another as a fundamental feature of software engineering. For successful privacy aware engineering, it is critical to guarantee the alignment and compliance among privacy artifacts emerging during software development process. In this paper, we propose a privacy compliance engineering flow in which we investigate the involved ...
