Ballistic Imaging of Transient Phenomena in Turbid Media

Ballistic imaging (BI) was developed as an optical diagnostic capable of ascertaining velocity and spatial information within dense sprays with relevance to liquid-fuel injection and combustion. This development includes a full model of light scattering within the complete imaging system, enabling the performance of the instrument to be examined, optimized and quantified. BI is a laser-based measu

Alexithymia in sleep disorder patients.

The purpose of the present study was to study associations between self-assessed alexithymia and sleep disorders. Five groups of patients with different sleep disorders were compared on the Toronto Alexithymia Scale (TAS-20). The prevalence of alexithymia, as defined by the cut-off score of TAS >60 was 17% among all patients, but differed among the groups: Primary Insomnia (PRI, n = 119) 6.7%, Ins

Product engineering by the paper dryer

The design of product properties is the main task for all process industries. The quality parameters, transport phenomena and mechanical parameters are closely coupled and all these phenomena must thus be taken into account at the same time to understand the development of product properties. In this work the importance of transport phenomena for paper quality parameters in the paper dryer will be

Betrayal and Betrayers - the Sociology of Treachery

Betrayal has a deep fascination. It captures our imagination in part because we have all betrayed or been betrayed, in small or large ways. Despite this there has been very little serious work on the subject. Betrayal is a breach of trust, when informants share beyond an agreed upon boundary of relations, whether that boundary is a pair of friends or a nation. Taking as a point of departure Simme

Human eeg responses to exact and statistical fractal patterns.

Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,
