    Abstract : Development of civilization faces a challenge of developing the resources of energy demand for the modern life. Extensive use of conventional fuel resources like crude oil and coal rise up a serious problem of increasing CO2 emission. New records levels of CO2 were registered during the early beginning of industrial revolution (http://climate.nasa. READ MORE

  3. 3. Asthenopia in schoolchildren

    Author : Saber Abdi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Asthenopia; prevalence; accommodative insufficiency; convergence; binocular disorders; refractive errors; Visual Analogue Scale; eye movements and reading;

    Abstract : Asthenopia is a term used to describe different symptoms associated with the use of the eyes, such as pain, blurred vision, diplopia, headaches. Asthenopia is most often reported in association with near vision. Children with asthenopia complain of such symptoms particularly when reading and writing. READ MORE

    Abstract : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. READ MORE

  5. 5. EMI from Switched Converters – Simulation Methods and Reduction Techniques

    Author : Andreas Henriksson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state space methods; EMI; semiconductor device modeling; diode reverse recovery; diode modeling; conducted emissions; Semiconductor device measurements; DC DC converters;

    Abstract : In this thesis, the conducted EMI from switched power converters has been analyzed using various existing models, own-derived models as well as measurements. The ingoing passive components in a switching converter have been modeled with respect to their high frequency behavior and the static and dynamic behavior of the active semiconductors has been analyzed.
