The increased impact from fluctuating energy sources like wind and photovoltaics significantly affects the operational regime of conventional power plants. In the near future, even former base load power plants such as the large-scale lignite plants in Germany will need to start and shut down to balance the electricity system. As frequent starts were not in the focus of optimisation in the past, a
Although differentiated cells normally retain cell-type-specific gene expression patterns throughout their lifetime, cell identity can sometimes be modified or reversed in vivo by transdifferentiation, or experimentally through cell fusion or by nuclear transfer. To examine the epigenetic changes that are required for the dominant conversion of lymphocytes to muscle, we generated heterokaryons bet
Popular Abstract in Swedish En av de mest fundamentala funktionerna för vårt långtidsminne är funktionen att kunna plocka fram ett specifikt minne när vi stöter på en ledtråd som är relaterad till detta minne. Ett vardagsexempel på sådan ledtrådsstödd långtidsminnesframplockning är om en vän frågar dig hur långt ett maraton är (en ledtråd som sökningen i långtidsminnet kan baseras på) och du lyckaA fundamental function of long-term memory is the ability to retrieve a specific memory when encountering a retrieval cue. The purpose of this dissertation was to further our understanding of such cued recall by investigating the temporal dynamics from the presentation of the retrieval cue until the target memory is recalled. Retrieval cues are often related with several memories. When such a retr
This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. However, it is still not entirely clear how much it can be trusted for precision
The study of localized deformation in porous sandstones at the laboratory scale can yield valuable insights into the internal structures and mechanisms of shear zones and compaction bands that might impact on flow at a reservoir scale. Herein, we report results of a laboratory study of shear and compaction band formation in a porous sandstone using a range of full-field experimental techniques: ac
It has been known that load unaware channel selection in 802.11 networks results in high level interference, and can significantly reduce the network throughput. In current implementation, the only way to determine the traffic load on a channel is to measure that channel for a certain duration of time. Therefore, in order to find the best channel with the minimum load all channels have to be measu
In the scope of a Swedish research project on expert knowledge as a basis for legal decisions, this article focuses on serious criminal cases. Using a model that describes rhetorical situations as well as empirical material based in 150 court decisions, the aim is to analyze the conditions surrounding the use of expert evidence in criminal law processes, to what extent and by whom such evidence is
In the area of adapting/constructing homes and workplaces for the physically disabled, a computer-based planning tool has been prototyped and evaluated. The prototypes so far have been based on Macintosh computers and commercially available 3-D modeling and multimedia programs. Six case-studies formed the basis for user-oriented prototyping and evaluation. The present prototype was found useful in
As farms are getting bigger with more animals, less manual supervision and attention can be given the animals on both group and individual level. In order not to jeopardize animal welfare, automated supervision is in some way already in use. Function and control of ventilation is already in use in modern pig stables, e.g. by the use of sensors for temperature, relative humidity and malfunction con
This study investigates how communication consultants struggle to reconstruct their professional role in the digital media landscape. The extant literature on professional roles in public relations has a tendency to render roles as static pregivens. Therefore, the purpose of this study is to contribute conceptually and empirically to role research by focusing on the process of “role-making” and ho
We consider the problem of designing demodulators for channels with memory that use reduced-size trellis descriptions for the received signal. We assume an overall iterative receiver, and for the parts of the signal not covered by the trellis description, we use interference cancellation based on the soft information provided by the outer decoder. In order to reach a trellis description, a linear
Following the EU declaration from 2016 on schools as the most crucial places for societal change needed in order to strengthen democracy, this chapter discusses Nordic music education and music education research within the context of shared challenges in times of rapid demographic changes. Resting on emerging results from the authors’ research projects, the first theme to be discussed is music ed
We report on the synthesis of vertical InP nanowire arrays on (001) InP and Si substrates using template-assisted vapour–liquid–solid growth. A thick silicon oxide layer was first deposited on the substrates. The samples were then patterned by electron beam lithography and deep dry etching through the oxide layer down to the substrate surface. Gold seed particles were subsequently deposited in the
The subgrade is the top surface of a roadbed upon which the pavement structure is constructed. The purpose is to provide a platform for construction of the pavement and to support the pavement without unwanted deflection that would reduce its performance. For those reasons subgrade bearing capacity have to be investigate during the construction process as a quality control, based on the design res
Edinburgh was an Enlightenment city of regional, national and global influence. But how did the people of Enlightenment Edinburgh understand and order their world? How did they encounter, compare and produce different kinds of spaces, from the urban to the world scale? And how did this city set the universal standards by which other places should be judged and transformed?The Geographies of Enligh
The commercial availability of low-cost millimeterwave (mmWave) communication and radar devices is starting to improve the adoption of such technologies in consumer markets, paving the way for large-scale and dense deployments in fifthgeneration (5G)-and-beyond as well as 6G networks. At the same time, pervasive mmWave access will enable device localization and device-free sensing with unprecedent
In this work, a derivation and implementation of the relativistic time-dependent configuration-interaction singles (RTDCIS) method is presented. Various observables for krypton and xenon atoms obtained by RTDCIS are compared with experimental data and alternative relativistic calculations. This includes energies of occupied orbitals in the Dirac-Fock ground state, Rydberg state energies, Fano reso
