  1. 36. Manipulation of Ocular Aberrations in Myopes

    Författare :Baskar Theagarayan; Jörgen Gustafsson; Frank Schaeffel; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myopia; Spherical aberration; Accommodation; Contact lens; Visual acuity; Peripheral aberrations; Optometry; Optometri; Optometry; Optometri;

    Sammanfattning : Myopia is a major cause of vision loss throughout the world. High myopia is associated with severe eye diseases like maculopathy, retinal detachment and glaucoma. The prevalence of myopia is increasing, and varies by country and by ethnic group. In some Asian populations the prevalence is 70%-80%. LÄS MER

  3. 37. Diabetes Mellitus Glucose Prediction by Linear and Bayesian Ensemble Modeling

    Författare :Fredrik Ståhl; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diabetes; Glucose Prediction; Identification; Ensemble Prediction;

    Sammanfattning : Diabetes Mellitus is a chronic disease of impaired blood glucose control due to degraded or absent bodily-specific insulin production, or utilization. To the affected, this in many cases implies relying on insulin injections and blood glucose measurements, in order to keep the blood glucose level within acceptable limits. LÄS MER

  4. 38. Semiconductor Nanowires: Characterization and surface modification

    Författare :Sofie Yngman; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; semiconducting nanowire; atomic force microscopy; Scanning tunneling microscopy; X-ray Photoelectron Spectroscopy; Scanning Probe Microscopy; Nanowires; Sveptunnelmikroskopi; Atomkraftsmikroskopi; XPS; Halvledarfysik; nanotrådar;

    Sammanfattning : The topic of III-V nanowires is still, after more than two decades, a growing and lively research area. The areas of application are wide and contain such important topics as energy harvesting, cheap and efficient lighting, high efficiency detectors and new types of electronics. III-V materials offer properties superior to the widely used Si. LÄS MER

  5. 39. Modelling of cavity partial discharges at variable applied frequency

    Författare :Cecilia Forssén; Roland Eriksson; Hans Edin; Peter H.F. Morshuis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial discharges; measurements; modelling; variable frequency; cavities; disc-shaped; polycarbonate; Electric power engineering; Elkraftteknik;

    Sammanfattning : The presence of partial discharges (PD) in high voltage components is generally a sign of defects and degradation in the electrical insulation. To diagnose the condition of high voltage insulation, PD measurements is commonly used. LÄS MER

  7. 40. Firm dynamics and competition in the electricity market

    Författare :Aili Tang; Lars Hultkrantz; Magnus Lodefalk; Niklas Jakobsson; Robert Lundmark; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Firm growth; profitability; steady-state; market power; competition; Boone indicator;

    Sammanfattning : This thesis consists of four independent essays that deal with the firm dynamics and competition in the electricity market. Specifically, it addresses two important facets of firm dynamics, namely, firm performance (growth and profitability) and the change in competition intensity that Swedish electricity firms face, brought by the process of deregulation in Swedish electricity market.
