2. 1. Quantitative microscopy of coating uniformity

   Author : Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

   Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

4. 2. Dynamics of Coinfection : Complexity and Implications

   Author : Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. READ MORE

5. 3. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

   Author : Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Abstract : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. READ MORE

6. 4. The Effect of Different Perturbations on the Stability Analysis of Light Water Reactors

   Author : Victor Dykin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; BWR and PWR stability; stability indicators; propagating density perturbation; autocorrelation function; density wave oscillations; decay ratio; non-white driving force; damped harmonic oscillator; reduced order models; Green s function technique;

   Abstract : Neutron noise analysis techniques are studied and developed, with primary useof determining the stability of Boiling Water Reactors (BWRs). In particular, the role ofa specific perturbation prevailing in Light Water Reactors, the propagating densityperturbation, in the stability of BWRs and on the noise field of LWRs in general, isinvestigated by considering three topics.

7. 5. Adaptive analysis of functional MRI data

   Author : Ola Friman; William M. Wells III; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Functional Magnetic Resonance Imaging (fMRI) is a recently developed neuroimaging technique with capacity to map neural activity with high spatial precision. To locate active brain areas, the method utilizes local blood oxygenation changes which are reflected as small intensity changes in a special type of MR images. READ MORE
