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.

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
The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over two decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to di
e consider waveform iterations for dynamic coupled problems with respect to therole of time window length. We review existing theoretical results about the error of waveformiterations and the role of the time window length. Furthermore, we present numerical resultsfor waveform iterations with both time adaptive sub solvers and with fixed time steps. Thisway, we are able to give a recommendation on
Binaural hearing aids communicate with each other through a wireless link for synchronization. A propagation model is needed to estimate the ear-to-ear link loss for such binaural hearing aids. The link loss is a critical parameter in a link budget to decide the sensitivity of the transceiver. In this paper, we have presented a model for the deterministic component of the ear-to-ear link loss. The
Type 2 diabetes mellitus is characterized by a low-grade inflammation; however, mechanisms leading to this inflammation in specific tissues are not well understood. The eye can be affected by diabetes; thus, we hypothesized that inflammatory changes in the eye may parallel the inflammation that develops with diabetes. Here, we developed a non-invasive means to monitor the status of inflammatory de
BACKGROUND: Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use
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
Background: Medial plica is a structure with limited understanding of its pathology, but it may be related to the development of medial knee osteoarthritis (OA). We examined the association between medial plica and medial meniscus extrusion (MME), progression of MME, and the risk of early-stage knee OA development in middle-aged persons. Methods: A total of 340 subjects with tibiofemoral Kellgren–
Mobile Stroke Units (MSUs), which are specialised ambulances equipped with brain imaging devices and trained medical personnel, offer the potential for rapid on-site diagnosis and treatment, improving patient outcomes in prehospital stroke care. To fully realise their benefits, it is essential to strategically allocate. However, identifying optimal locations within a region for MSU deployment is t
Drought-induced canopy browning and recovery dynamics threaten ecosystem stability worldwide, with Australia serving as a representative case. This study examined the 2019–2020 drought and subsequent recovery in Eucalyptus forests across two bioregions of the Australian state of New South Wales (NSW): the North Coast and South Eastern Highlands. Canopy browning and recovery were quantified using a
The human polymnaviruses JC virus (JCV) and BK virus (BKV) are oncogenic in experimental systems and commonly infect humans. JCV DNA has been reported to be present in human colon mucosa and in colorectal cancers. To investigate whether the risk for colorectal cancer is associated with JCV or BKV infection, we performed a case-control study nested in the Janus biobank, a cohort of 330,000 healthy
BACKGROUND: Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigati
