This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). The study in this thesis is restricted to a parallel hybrid vehicle equipped with a diesel engine, two electric machines
In modern cancer therapy, radiotherapy (RT) is a vital part of most treatments. Most RT treatments in Sweden are performed using intensity-modulated radiotherapy (IMRT) with fixed or dynamic arc delivery. The dose gradients outside the target are steep, the margins are small, and the treatment delivery is complicated. Complicated treatments increase the requirement for control of the uncertaintiesIn modern cancer therapy, radiotherapy (RT) is a vital part of most treatments.

In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. The simulation models included in this thesis are the result of collaboration with Petter Strandh at the D
The paper is concerned with estimation of heat and power consumption in a conceptual plant to produce hydrogen from sucrose-containing or starchy biomass by fermentation. A hydrogen plant connected with a sugar factory is regarded as the basic option; the sugar factory serves as a source of sucrose-containing thick juice for the hydrogen plant, where this feedstock is processed to hydrogen. As ano
Engaging with the challenge of low carbon transitions and climate impacts requires new academic and political work. It involves more than an assessment of the feasibility, effectiveness and legitimacy of particular technologies, incentives, institutions or policies to address short-term targets and timetables. As such, in the domain of climate change our political and ethical choices are criticall

Popular Abstract in English In the age where there is a great demand of energy, raise in the prices of fossil fuels and increase of environmental concerns because of the greenhouse gas emissions, biogas production through anaerobic digestion, of different organic materials, provides a full or partial solution. There is a large number of cheap substrates as organic waste materials that can be utili
Anders Mikkelsen, Professor at Lund University and Director of NanoLund will present his research about an artificial neural network that is inspired by the central navigation complex in the insect brain. This seminar is given in the frame of series that is organized by the three nanoscience hubs located in the Copenhagen-Lund area. The aim is to to increase awareness about our mutual capabilities

Only three days after the beginning of the nuclear catastrophe in Fukushima, Japan, on 11 March 2011, the German government ordered 8 of the country's 17 existing nuclear power plants (NPPs) to stop operating within a few days. In summer 2011 the government put forward a law - passed in parliament by a large majority - that calls for a complete nuclear phase-out by the end of 2022. These governmen
Temperature measurements in trunks and branches in a mature ca. 100 years-old mixed pine and spruce forest in central Sweden were used to estimate the heat storage in the tree biomass. The estimated heat flux in the sample trees and data on biomass distributions were used to scale up to stand level biomass heat fluxes. The rate of change of sensible and latent heat storage in the air layer below t

This thesis dwells upon the synthesis of system-theoretical tools to understand and control the behavior of nonlinear networked systems. This work is at the crossroads of three topics: synchronization in coupled high-order oscillators, inverse optimal control and the application of inverter-based power systems. The control and stability of power systems leverages the theoretical results obtained f
Stakeholders are voicing concerns over the social and environmental impacts of components of Europe’s renewable energy strategy that will significantly increase the region’s demand for forest biomass. Energy companies must address these concerns if they are to manage financial, reputational, regulatory and competitive risks. Sustainability schemes may help reduce such risks by increasing the socia
