  3. 32. Effect of Surface roughness for Hydro Turbine Step-up Efficiency

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ermias Beraki; [2018]
    Keywords : Hydropower; Surface roughness; Hydro Turbine; Step-up Efficiency; IEC 62097 standard; Prototype and Model;

    Abstract : The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. READ MORE

  4. 33. Projecting invasive species using remote sensing and spatial explicit models

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Astrid Zimmermann; [2018]
    Keywords : Physical Geography; Ecosystem Analysis; Rosa rugosa; invasive species; aerial images; growth rate; modeling; cellular automata; Earth and Environmental Sciences;

    Abstract : An evaluation of the current and previous Rosa rugosa growth on Kieler Ort, Germany, with the aim to predict the rose coverage in future, under consideration of environmental factors. Kieler Ort, a rather isolated island in the southwest Baltic Sea is representing a unique environment which is protected for its landscape, nature, flora and fauna and serves as a bird sanctuary.

  5. 34. Analytical calculation model used when dimensioning timber poles used as overhead power line supports

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christopher Ekängen; [2018]
    Keywords : Calculation model; timber poles; overhead power line;

    Abstract : Overhead power lines are more reliable and cost effective than underground cables when it comes to power transmission. The overhead power lines are often suspended above ground using timber pole supports. READ MORE

  6. 35. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jennifer Eriksson; [2018]
    Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

    Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE
