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
