  1. 21. Experimental studies of corneal neovascularisation

    Författare :Branka Samolov; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The cornea contains no vessels, which is a prerequisite for the maintenance of its transparency. Vessel ingrowth leads to opacification resulting in visual impairment, sometimes complete blindness. LÄS MER

  3. 22. Understanding Mobility and Transport Modal Disparities Using Emerging Data Sources: Modelling Potentials and Limitations

    Författare :Yuan Liao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; data mining; geographical information systems; mobility models; big trip data; transport modes; traffic data; social media data;

    Sammanfattning : Transportation presents a major challenge to curb climate change due in part to its ever-increasing travel demand. Better informed policy-making requires up-to-date empirical mobility data to model viable mitigation options for reducing emissions from the transport sector. LÄS MER

  4. 23. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

    Författare :Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

    Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

  5. 24. Local Signal Models for Image Sequence Analysis

    Författare :Jörgen Karlholm; Gösta Granlund; Patrick Bouthémy; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The thesis describes novel methods for image motion computation and template matching.A multiscale algorithm for energy-based estimation and representation of local spatiotemporal structure by second order symmetric tensors is presented. LÄS MER

  7. 25. Present and future precipitation variations in the source region of the Yangtze River, China

    Författare :Yiheng Du; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Precipitation; water balance; ENSO; PDO; Yangtze River; Tibet Plateau; future projections;

    Sammanfattning : The source region of the Yangtze River (SRYR), the origin of the longest river in China, is an area with high-mountains and river ecotones that face considerable challenges under climate change. Precipitation is fundamental for sustainable ecosystems in this area and for the downstream water supplies. LÄS MER
