1. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations
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. Colour in Enclosed Space Observation of Colour Phenomena and Development of Methods for Identification of Colour Appearance in Rooms
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. Energy in supermarkets - An overview on the energy flows and refrigeration controls
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. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints
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. From Ants to Service Robots : an Exploration in Stigmergy-Based Navigation Algorithms
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
