  1. 1. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations

    Författare :Yichi Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; demand-side management; low energy buildings; Thermal energy storage; district heating; variable renewable energy;

    Sammanfattning : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

  2. 2. Colour in Enclosed Space Observation of Colour Phenomena and Development of Methods for Identification of Colour Appearance in Rooms

    Författare :Monica Billger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; identity colour; simultaneous contrast; illumination; reflections; colour; visual assessments; interiors; adaptation effects; full-scale studies; colour appearance;

    Sammanfattning : The main problems dealt with in this thesis are (1) how colours can appear in rooms due to various colour combinations and lighting conditions, and (2) how we can identify and compare colour appearance in rooms. One aim is to demonstrate and discuss the complex problem of how certain conditions in a room affect colour appearance, and to give examples and describe the co-operation between some of the affecting factors in experimental rooms.

  3. 3. Energy in supermarkets - An overview on the energy flows and refrigeration controls

    Författare :Tommie Månsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The electrical energy used by supermarkets represents approximately 3% of Sweden's annual energy use. Of this, the refrigeration system accounts for 50%. To reduce greenhouse gases introduced by energy generation, a larger share of renewable energy sources must be implemented. LÄS MER

  4. 4. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints

    Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRP steel joints; durability; fibre reinforced polymer; cohesive zone modelling; long-term performance; adhesively bonded joints; moisture diffusion;

    Sammanfattning : Fibre reinforced polymer (FRP) composites offer excellent properties, such as high specific strength and stiffness, corrosion resistance and light weight. Over the past four decades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

  5. 5. From Ants to Service Robots : an Exploration in Stigmergy-Based Navigation Algorithms

    Författare :Ali Abdul Khaliq; Alessandro Saffiotti; Federico Pecora; Andrea Omicini; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stigmergy; Minimalistic Robots; Mobile robot navigation; RFID technology; Multi-robot system; Path planning; Localization; Map building;

    Sammanfattning : Navigation is a core functionality of mobile robots. To navigate autonomously, a mobile robot typically relies on internal maps, self-localization, and path planning. Reliable navigation usually comes at the cost of expensive sensors and often requires significant computational overhead. LÄS MER
