  2. 1. High Efficiency Inductive Power Transfer Systems for Vehicle Charging

    Author : Daniel Pehrman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual-active bridge; power flow control; bi-directional; electric vehicles; electromagnetic fields; inductive power transfer; high efficiency; high power; three-phase;

    Abstract : Awareness of climate change due to greenhouse gas emissions and air pollution has led to a transition from internal combustion engine vehicles to electric vehicles. Wireless charging by inductive power transfer is a promising solution for charging electric vehicles. READ MORE

  4. 2. Office illness : the worker, the work and the workplace

    Author : Berndt Stenberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sick Building Syndrome; Indoor Air Syndrome; facial skin symptoms; constitutional factors; psychosocial factors; indoor air quality; outdoor air flow rate; electromagnetic conditions; VDT work;

    Abstract : The work started with the clinical observations in patients working in buildings with indoor air problems. Signs of seborrhoeic dermatitis, erythematous facial skin conditions and itching conditions on the trunk were noted. Another point of departure was the attribution of facial skin symptoms to VDT work by patients. READ MORE

  5. 3. EnviroMT : A new controlled source/radio magnetotoelluric system

    Author : Mehrdad Bastani; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; EnviroMT; RMT; CSTMT; Geofysik; Geophysics; Geofysik;

    Abstract : In the frame of an EU project, a new electromagnetic prospecting instrument was designed and constructed for environmental and engineering applications. The instrument works in the frequency domain in the band 1-250 kHz, whereby the collected data can be used to study the variation of ground resistivity from the surface to a maximum depth of few hundred meters.

  6. 4. The dielectric properties of solid biofuels

    Author : Ana Marta Paz; Erik Dahquist; Ebbe Nyfors; Mälardalens högskola; []
    Keywords : dielectric properties; solid biofuels; moisture content determination; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The use of bioenergy has been increasing due to efforts in fossil fuels replacement. Modern bioenergy technologies aim for high efficiency and low pollution levels, which increases the need for methods for the on-line characterization of biofuels. READ MORE

  7. 5. On leachate emissions from municipal solid waste

    Author : Martijn van Praagh; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; Miljöstudier; Environmental studies; Environmental Impact; heavy metals; Organic carbon; teknisk geologi; Hydrogeologi; geographical and geological engineering; teknisk geografi;

    Abstract : When attention is drawn to the recovery of resources within waste, the amount and types of waste disposed of at landfills change. A waste management system based on separate kerbside collection, sorting, recycling, and pretreatment with material and/or energy recovery produces new residues, which finally end up at landfills.
