Monte Carlo simulation is a numerical method that can simulate complex physical systems and is widely used in the field of medical optics. For example, the Monte Carlo method was used to evaluate the effectiveness of near-infrared spectroscopy (NIRS) in the detection of intracranial hematoma (ICH). However, due to the relatively complex brain structure, the current simulation model is relatively s
Spatial transcriptomics, a powerful technique that merges sequencing and spatial data, offers unprecedented resolution for studying gene expression within tissues. This study focuses on developing a pipeline to design probes for Multiplexed Error-Robust Fluorescence In Situ Hybridisation (MERFISH) experiments to investigate the spatial distribution of the lung microbiome. Metagenomic data analysis
Att skapa en cirkulär ekonomi med hållbara produkter är en nödvändighet för dagens samhälle, särskilt kopplat till de klimatutmaningarna som vi har idag från bland annat överkonsumtion och dålig hantering vid slutet av produkternas livslängd. Projektet fokuserar på att ta fram en produkt som gjorts på återvunna material och att utmana tidigare materialbegränsningar. Detta har gjorts med en betonin
Most electricity in Lebanon is produced by burning fossil fuels, which produces more than one half of domestic greenhouse gas emissions, and the state-owned electricity companies are unable to meet the demand. To increase the country’s generation capacity and simultaneously combat the effects of climate change, the government aims to produce 30% of its electricity from renewables by 2030. It is ho
A Jacobian free multigrid preconditioner for linear problems arising from Implicit Discontinuous Galerkin (DG) discretizations is implemented. The preconditioner is based on a multigrid method for a low order Finite volume (FV) discretization on a subcellgrid. L2-projections are introduced as a strategy to translate between the discretizations. Numerical tests on advection dominated linear advecti
Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. I denna uppsats utforskas möjligheten att applicera metoden med digitalkameror på ett nyligen kalhugget område för aAbstract The use of inexpensive digital cameras in phenological research has been acclaimed since results in previous research have shown that they are reliable and precise in measuring greenness of vegetation. The work of this thesis aims to broaden the applicability by studying how well the method performs when measuring the regrowth of a clear-cut area. This is needed to complement existing res
The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main
This thesis investigates the stock return and its variance around seasoned equity offering announcements for Swedish companies listed on the OMX Large cap, Mid cap and Small cap exchanges. The analysis is made on a full sample containing 52 SEOs, as well as two sub-samples containing underwritten and non-underwritten SEOs. The framework for the event study is OLS regressions based on the CAPM-mode
As the spread of the internet continues, more people than ever search for medical information online when in need of health advice. Color is a prominent part of website aesthetics, and has been shown in the literature to have both positive and negative psychological effects. A total of 120 participants took part in the present study where the effect of the colors grey, blue, orange and red was tes
Popular science summary: Potential Distribution for the Endangered Asian Wild Ass Over the past century, large mammals have been globally under increasing pressure of humanized landscapes. Since extirpations of large herbivores are likely to have complicated consequences for the entire ecosystem, their conservation is a priority. With almost 81% threatened species, Perissodactyla (odd-toad ungu
The debate about the link between economic growth and foreign trade is still open amongst scholars. There exist four main hypotheses regarding the relation between imports, exports and economic growth. The first one states that growth can come only through increasing the volume of exports of the country, i.e. export – led – growth hypothesis. The second one (growth – led – exports hypothesis)
The Magoye River is located in the Southern Province of Zambia. This is the most drought prone region in Zambia and a lot of water bodies dry up during the dry seasons, including the Magoye River. Small scale livestock farming is widespread in the area and low water availability during dry seasons forces local farmers to push their cattle long distances for drinking water and grazing during dry se
Bröstcancer är den vanligaste formen av cancer hos kvinnor. Fler än 7000 diagnostiseras med denna sjukdom varje år i Sverige. En del av behandlingen mot cancern är strålbehandling. För att strålbehandlingen ska ge goda effekter är det viktigt att det är den sjuka vävnaden som bestrålas, och att den friska vävnaden förskonas från strålningen i den mån det är möjligt. Detta uppnås genom noggranna stPurpose: The CatalystTM system was tested and compared with an X-ray image verification system for patient positioning during breast cancer treatment. Included was to find the optimal reference image and the optimal cropping method for the reference image. Parameters that could lead to an optimization of the treatment routines were also evaluated. Method and Material: The study was divided into t
In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. This thesis introduces a linear algebra framework for closed orbit perturbation and correction, its implementation as a Python package and its use for three studies in HL--LHC: orbit corrector bu
To develop treatments for currently uncurable neurological disorders, more knowledge is needed of the involved neural circuits and changes in gene expression. The padlock probe technique, in which linear DNA probes are circularized and amplified when hybridized to their cDNA target sequence, has previously been used for both multiplexed gene detection and neuronal projection mapping in brain tissu
This study arises from an existential concern that there is an obliviousness in academia with regards to the recent eruption of the transhumanist movement–an ideological force imbued with potentially calamitous socioecological consequences. With the support from recent claims that the transhumanist ideology exerts powerful influence on Western politics, this study seeks to investigate how the tran
Due to the changing nature of employment, contemporary early career employees place more value on work-life balance than any other generation before them. Our purpose is to provide a contextual overview that identifies and illuminates some of the defining characteristics of the early career employees employed in the banking sector. The integration of the boundary and motivation theory enable us to
