The Volvo Car Corporation experience diversities in the price development of the four different business areas electronics, interior, exterior and chassis and power train. The purpose of this master thesis was to investigate if there are any structural differences that give the suppliers different prerequisites for productivity development thus different prerequisites for price reductions. When co
Solar power and electric vehicles (EV) are set to play a leading role in the achievement of the 2030 EU renewable targets and the commitment to carbon neutrality by 2050. Importantly, solar photovoltaics (PV), in combination with energy storage, also has the potential to significantly enhance European energy security, provide citizens and industry with competitive energy, and lead to the creation
In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite nu
In vivo mapping of the neurite density with diffusion MRI (dMRI) is a high but challenging aim. First, it is unknown whether all neurites exhibit completely anisotropic (“stick-like”) diffusion. Second, the “density” of tissue components may be confounded by non-diffusion properties such as T2 relaxation. Third, the domain of validity for the estimated parameters to serve as indices of neurite den
The thermal environment experienced by birds during early postembryonic development may be an important factor shaping growth and survival. However, few studies have directly manipulated nest temperature (T n) during the nestling phase, and none have measured the consequences of experimental heat stress on nestlings’ body temperature (T b). It is therefore not known to what extent any fitness cons
There exists a non-closed formula for the American put option price and non-trivial computations are required to solve it. Strong efforts have been made to propose efficient numerical techniques but few have strong mathematical reasoning to ascertain why they work well. We present an extension of the American put price aiming to catch weaknesses of the numerical methods based on their non-fulfillm
Recent news of an impending clinical cell transplantation trial in Parkinson's disease using parthenogenetic stem cells as a source of donor tissue have raised hopes in the patient community and sparked discussion in the research community. Based on discussions held by a global collaborative initiative on translation of stem cell therapy in Parkinson's disease, we have identified a set of key ques
Gaza has several water problems; limited fresh water supply, inefficient water use by the agricultural sector, high water demand, groundwater contamination, seawater intrusion and shortage of electricity. Water and electricity is the first priority for Gaza that will add significant positive values to the Palestinians living in blocked Gaza and easy operation and maintenance of their ongoing and e
Nowadays, the use of digital signal processing is essential in various measurements of different machines. There has been many projects done at Sandvik AB on how to collect and measure data signals on the cone rock crusher. None of those measurements could present the correct data. The reason could possibly be due to the lack of theory behind the use of digital signal processing which this thesis
Wheat is our most cultivated grain and has been used as human food for thousands of years, but as the population increases, so does the demand for grain. Challenges that we face today are that the amount of cultivable arable land is decreasing, that climate change is affecting crop yields, while people's concerns are growing about the use of chemical pesticides. It is therefore of great intere
I have always been curious about the effects architecture and the built environment have on us. The special atmosphere and the ability to arouse a sense of safety and calmness, but also the negative feelings certain spaces can evoke. Which architectural elements contribute to the way we perceive a space and more importantly, does the built environment not only affect our emotions but also our ment
We consider the Boussinesq equation on the line for a broad class of Schwartz initial data relevant for water waves. In a recent work, we identified ten main sectors describing the asymptotic behavior of the solution, and for each of these sectors we gave an exact expression for the leading asymptotic term in the case when no solitons are present. In this paper, we derive an asymptotic formula in
The Value of Information from Bayesian decision theory can be used to drive decisions within the development of new technologies aiding research screening, technology characteristics, and employment optimization. The selection of a specific application of technology leads to the definition of the decision scenario within the Value of Information framework. Technological performance characteristics
To meet climate targets, expanding Populus spp. tree cultivation is proposed as a potential biomass feedstock, especially on agricultural land that does not come into conflict with food production. However, biomass potential assessments typically overlook landowners' perspectives, risking a gap between theoretical potentials and realisation. Here, we test empirical consequences of two hypotheses b
The use of a learning management/assessment system has become common in higher education during the past 20 years. However, such systems are frequently not grounded in approaches to support longitudinal educational needs, such as promoting professional development. One reason may be that digital support is designed to assist with isolated tasks e.g. running MCQ tests, and therefore is not develope
