  2. 1. Modeling and analysis of offshore hybrid power parks

    Author : Erik Jonasson; Irina Temiz; Hans Bernhoff; Jon Olauson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : In the past decade, the global share of fossil-based electricity generation has decreased from 67% to 61% in favor of renewable alternatives. To achieve global goals, a continued extensive expansion of electricity generation from renewable energy sources is necessary. READ MORE

  4. 2. Monitoring the cellular phosphate status in bloom-forming cyanobacteria of the Baltic Sea

    Author : Sara Jonasson; Erik Söderbäck; Hans C. P. Matthjis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; Baltic Sea; phosphorus; cyanotoxin; nodularin; Plant physiology; Växtfysiologi;

    Abstract : In the Baltic Sea dense cyanobacterial blooms occur regularly during late summer. Since the dominant bloom-forming cyanobacteria, Nodularia spp. and Apanizomenon spp. are capable of fixing atmospheric dinitrogen, the macronutrient predominantly limiting their growth is phosphorus.

  5. 3. Tyre-road Interaction: a holistic approach to noise and rolling resistance

    Author : Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Anders Genell; Hans Jonasson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement; surface; texture; noise; rolling resistance; tyre; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Energy dissipation, fuel consumption, real-estate property prices and health issues are some of the aspects related to the tyre/pavement interaction and its functional properties of rolling resistance and noise. The first two aspects are affected by the tyre/road interaction as energy is dissipated mostly by hysteretic losses as the tyre is subjected to dynamic deformations when contacting the pavement surface.
