  1. 21. Comparison of energy efficiency between macro and micro cells using energy saving schemes.

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Koustubh Sharma; [2017]
    Nyckelord :Hetnets; Energy Efficiency; EARTH Power Model; Macro cells; Micro cells; LTE; 5G; Heterogeneous Networks; Energy Saving Schemes.; Technology and Engineering;

    Sammanfattning : With the rapid development of Information and Communication Technology (ICT) industry the demand for power has also increased. ICT tends to play a significant role in global greenhouse gas emissions. It was responsible for 10% of world’s total energy consumption in 2010 and is doubling in every 10 years [1]. LÄS MER

  3. 22. Comparison of different reactor configurations for ex‐situ biological biogas upgrading

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Hugo Porté Laborde; [2016]
    Nyckelord :;

    Sammanfattning : Climate change is one of the major challenges of the 21st century. The energy sector represents the main contributor to global greenhouse gas emissions, due to its reliance on fossil fuels. Renewable energies arise as current solutions. LÄS MER

  4. 23. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Ran Li; [2015]
    Nyckelord :Multi-layered thermal barrier coating; isothermal oxidation; suspension plasma spray;

    Sammanfattning : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. LÄS MER

  5. 24. How to handle boil-off gases from LNG trucks

    Master-uppsats, Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

    Författare :Linda Gunnarsson; Erik Helander; [2015]
    Nyckelord :LNG; Liquefied natural gas; boil-off; boil-off gases; BOG; natural gas;

    Sammanfattning : This master thesis project aims to investigate the circumstances of boil-off for heavy vehicle transports, using LNG as fuel, and suggest possible ways of handling these gases otherwise released into the atmosphere. LNG, Liquefied Natural Gas, is when natural gas is cooled below its vaporisation point, turning it into liquid phase which is a much more dense way of storing and transporting the fuel. LÄS MER

  7. 25. Modeling and implementation of dense gas effects in a Lagrangian dispersion model

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Niklas Brännlund; [2015]
    Nyckelord :Dense gas; Lagrangian dispersion model; Langevin equation; Stochastic modeling; Accidental releases;

    Sammanfattning : The use of hazardous toxic substances is very common in the industrial sector. The substances are often stored in tanks in storage compartments or transported between industrial premises. In case of an accident involving these substances, severe harm can affect both population and the environment. LÄS MER
