  1. 1. District heating comes to town : The social shaping of an energy system

    Författare :Jane Summerton; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; district heating; municipal technology; energy system; pipeline; large t<:chnical system; actor network; multiorganization; grid; grid-based energy system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This thesis deals with the introduction of district heating in an "ordinary" Swedish town: Mjölby. The process was initiated in 1974 and the decision to build was taken in 1979. In the following years pipelines were laid down and the system was gradually built. In 1987, a permanent heat plant was ready to assume operation. LÄS MER

  3. 2. Voyage optimization algorithms for ship safety and energy-efficiency

    Författare :Helong Wang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; Dijkstra’s algorithm; Voyage optimization algorithms; Genetic algorithm; Ship safety; Expected time of arrival;

    Sammanfattning : Currently, over 90% of the world’s trade is transported by sea. The environmental impacts from shipping and societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry for more energy efficiency and enhanced safety. LÄS MER

  4. 3. Control of a Multi-terminal VSC-HVDC system - A general Control System Structure

    Författare :Evripidis Karatsivos; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Environmental impact and security of supply has fuelled a shift in the power mix of power systems today. Traditionally used fossil fuel gives more and more space to the development of renewables in an effort to comply with strict international standards regarding CO2 emissions and secure energy supply.

  5. 4. Towards Enabling Exploration of Planetary Subterranean Environments using Unmanned Aerial Vehicles

    Författare :Akash Patel; George Nikolakopoulos; Savvas Loizou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : This thesis presents a novel navigation framework established to enable the exploration of planetary subterranean areas with Unmanned Aerial Vehicles (UAVs). The key contributions of this thesis work form a robot-safe rapid navigation framework that utilizes a novel bifurcating frontier-based exploration approach. LÄS MER

  7. 5. The Impact of Non-synchronous Generation on Power Systems Dynamics

    Författare :Harold Chamorro; Mehrdad Ghandhari; Jonas Persson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Due to the increasing integration of Renewable Energy Sources (RES), and the installation of High Voltage Direct Current (HVDC) systems, more power is injected to the AC grid based on power electronic converters. This kind of power injection is called non-synchronous generation in this thesis. LÄS MER
