Continuously indexed Gaussian fields (GFs) are the most important ingredient in spatial statistical modelling and geostatistics. The specification through the covariance function gives an intuitive interpretation of the field properties. On the computational side, GFs are hampered with the big n problem, since the cost of factorizing dense matrices is cubic in the dimension. Although computational
The accuracy, precision and limitations of the imaging technique named Structured Laser Illumination Planar Imaging (SLIPI) have been investigated. SLIPI, which allows multiply scattered light to be diminished, has previously demonstrated improvements in image quality and contrast for spray imaging. In the current study the method is applied to a controlled confined environment consisting of a mix
A lot of companies have data that can be used to develop a more successful business. To become more data-driven, it is important to extract valuable information from the raw data. One of the largest challenges for companies, while trying to make this transition, is to ensure a data quality at a high level. In this thesis, we worked with Alfa Laval’s database of previously sold products. The main i
The wood pulp industry has been around for a long time, but new higher quality pulp require more advanced solutions to old processes. One of these processes is the peroxide (PO) bleaching process, which is the last of a whole chain of bleaching processes at the Mörrum pulp processing plant. The aim of this thesis was to develop and study a model for the peroxide pulp bleaching process, and thereaf
Humanitarian logistics (HL) is a relatively new research area that requires clear boundaries and a defined foundational perspective. Recent disasters have shown that the scope of HL is expanding, as in cases of cash-based interventions, outsourcing to commercial companies, and stronger involvement of local communities. These changes imply the importance of scrutinizing the old definitions of HL an
Remote sensing precipitation data have the characteristics of wide coverage and revealing spatiotemporal information, but their spatial resolution is low. The accuracy of the data is obviously different in different study areas and hydrometeorological conditions. This study evaluated four precipitation products in the Yellow River basin from 2001 to 2019, constructed the optimal combined product,
Det är ofta arkitekter får frågan “Varför ritar ni så fula hus nuförtiden?”. Majoriteten lekmän tycks föredra estetiken hos äldre hus framför det som byggs idag. Ämnet är aktuellt i olika medier, men problemet är att det sällan bedrivs en konstruktiv diskussion mellan de två sidorna. Förespråkarna för en mer traditionell arkitektur smutskastar arkitekterna och arkitekterna hånar kritikerna. I mittArchitects are often asked the question ”Why do you design such ugly buildings nowadays?”. The majority of laymen seem to prefer the aesthetics of, what might be referred to as period or traditional houses, to what we build today. The issue is being much discussed in the media, but in general, the discussions are not constructive. People that advocate a traditional architecture excoriate architect
Skadeståndsprocesser mot styrelseledamöter har historiskt varit ovanliga i Sverige men antalet fall har ökat på senare år. Styrelseledamöters skadeståndsansvar regleras i 29 kap. 1 § aktiebolagslagen (ABL) och av särskilt intresse för denna framställning är de fall där styrelseledamöterna orsakat skada för bolaget genom dåliga affärsbeslut. I USA skyddas styrelseledamöter i dessa fall av business Claims for damages against board members have historically been unusual in Sweden but have started to increase in recent years. The responsibility of board members is regulated in the 29th chapter 1 § of the Swedish Companies Act (SCA) and of particular interest for this essay are the cases where the board has caused damage upon the company through bad business decisions. In such cases in the US,
Artificial intelligence is expected to be the next paradigm shift in technology, akin to the steam engine or electricity in its universality and all-encompassing impact. Regulating an innovation of this magnitude is important, however challenging, as evidenced by the European Union’s recently proposed Artificial Intelligence Act. This thesis sets out to understand the EU as a normative actor in th
Humanity is faced with multiple interconnected crises, ranging from the climate breakdown to searing inequalities. There is thus an urgent need to move towards a different socio-political-economic system. Degrowth scholars envision a post-capitalist society centered around ecological and social wellbeing. One way to get there is by building on existing interstitial initiatives. At the same time su
Pastoral farming formed a key element of Norse subsistence strategies in South Greenland but with climatic changes of the Little Ice Age they may have reached their limit. Most recently, studies into hydrological changes across the Norse period (10th-15th century AD) revealed a severe drying trend that was coincident with the Norse demise during the early to mid-15th century AD. This study examine
This study is a survey of the bottom life of Hjälmsjön outside Örkelljunga in Skåne. The municipal and a row society are going to make an application for permission to dredge the bottom in order to increase the depth up to two meters depth. In the application they need a description of the area including which species live on the bottom and what the ecological status is for the lake. I have sample
This thesis is dedicating to analysis the contribution of Knutpunkten building which is located in Helsingborg southern Sweden with regards to its visual impact role on the society and environment from its visual appearance of the elements of design mainly colour and light element. Different philosophical conceptions of colour and light from different theoretician notion is using as a main empiric
The thesis explores the interaction between patent rights for Standard Essential Patents(SEP) and competition law, particularly Article 102 of the Treaty on the Functioning of the European Union(TFEU), within the context of the European Union(EU) , and compares this interaction with the relevant provisions in the proposed EU SEP regulation COM(2023)232. Three research questions will be discussed:
Some large ecological studies have noted a significant association of testicular cancer (TC) with maternal smoking during pregnancy, while several more controlled studies have been negative. It has been difficult to obtain reliable data on exposure because of the long lag time to cancer diagnosis. We performed a case-control study nested within Finnish, Swedish and Icelandic maternity cohorts expl
In this work, we have evaluated the performance of a diffusion-sensitive fast spin-echo (FSE) pulse sequence. The proposed pulse sequence utilises velocity-compensating diffusion-encoding gradients and includes the collection of navigator echoes. Spoiler gradients were inserted in the slice-selecting direction to minimise effects from stimulated echoes. Calculations of the b values showed that cro
The five Nordic species of the genus Urytalpa Edwards (Diptera: Keroplatidae) are revised, of which one species, Urytalpa galdes Hedmark & Kjaerandsen, sp. n., is described as new to science based on males collected in northern Sweden. We find that the original type species assignment for Urytalpa (Platyura ochracea Meigen, 1818) is based on a misidentification, and in order to stabilize the n
PURPOSE: To identify regional arterial input functions (AIFs) using factor analysis of dynamic studies (FADS) when quantification of perfusion is performed using model-free arterial spin labelling. MATERIAL AND METHODS: Five healthy volunteers and one patient were examined on a 3-T Philips unit using quantitative STAR labelling of arterial regions (QUASAR). Two sets of images were retrieved, one w
Landscapes influence precipitation via the water vapor and energy fluxes they generate. Biologically active landscapes also generate aerosols containing microorganisms, some being capable of catalyzing ice formation and crystal growth in clouds at temperatures near 0 degrees C. The resulting precipitation is beneficial for the growth of plants and microorganisms. Mounting evidence from observation
