  1. 1. Diagnosing and monitoring open-angle glaucoma. Pupillometry and other novel techniques

    Författare :Lada Kalaboukhova; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :open-angle glaucoma; relative afferent pupillary defect; pupillometer; visual field; Frequency Doubling Technology Perimetry; High-pass Resolution Perimetry; Heidelberg Retina Tomography;

    Sammanfattning : Aim:To investigate the ability of a custom-built pupillometer and other novel diagnostic instruments to detect and monitor optic nerve damage in glaucoma.Methods:In the first two studies we investigated pupillary reactions to light in patients with glaucoma and in healthy persons using a custom-built pupillometer.

  2. 2. Time-Resolved Attosecond Spectroscopy of He Using COLTRIMS

    Författare :Predrag Ranitovic; Reinhold Schuch; C. L. Cocke; Robert Moshammer; AlbaNova University Center (together with KTH) Faculty of Science Stockholm University; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; attosecond spectroscopy; Physics; Fysik; Physics; fysik;

    Sammanfattning : Tunable ultrafast lasers are becoming a standard tool for probing and controlling the dynamics of atoms, molecules and chemical reactions. This thesis is a contribution to a large, ongoing effort to make spectroscopic tools for inducing and controlling, in real time, the natural processes which occur on the femto and attosecond times scales.

  3. 3. Development and application of Differential Optical Absorption Spectroscopy (DOAS) for Asian urban air monitoring and atmospheric research

    Författare :Yu Yong; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian cities; air pollution; DOAS; free radicals; aerosol; long-path absorption; emission sources; industrial emission; atmospheric chemistry;

    Sammanfattning : Urban air pollution is a serious concern in developing countries and there is a need for qualified measurements of a range of compounds on a nation-wide basis. A suitable potential technique for air monitoring is Differential Optical Absorption Spectroscopy (DOAS). LÄS MER

  4. 4. Verksamhetsinriktade produktstrukturer

    Författare :Leif Janson; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : The subject of this thesis is product development and design, based on a systematic approach. The study is based on [Hubka, V. Theory of Technical Systems. Springer Verlag, Berlin, Heidelberg, 1988] and the problem area is variance management and variation reduction due to increased product diversification. LÄS MER

  5. 5. Glaucoma Diagnostics

    Författare :Sabina Andersson; Oftalmologi (Malmö); []
    Nyckelord :POAG – glaucoma – diagnostic accuracy – screening – subjective assessment – population-based – GDx VCC – OCT – HRT – FDT – ONH assessment – CME – ANN – artificial neural network – visual field assessment;

    Sammanfattning : This thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice.
