1. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions
Sammanfattning : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. LÄS MER
2. Lighting Control Systems to Save Energy in the non-Residential Sector : State-of-the-art, Field Studies, and Simulations
Sammanfattning : This thesis examines the energy-saving potential for lighting when using traditional indoor LCSs in non-residential buildings. In the study, an overarching theoretical framework is used that distinguishes between energy efficiency and energy saving, as well as between energy use for lighting and functional illumination.

3. Iterative Road Grade Estimation for Heavy Duty Vehicle Control
Sammanfattning : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. LÄS MER
4. Distributed Road Grade Estimation for Heavy Duty Vehicles
Sammanfattning : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. LÄS MER
5. Dynamics of Energy Systems - Methods of analysing technology change
Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER
