Popular Abstract in Swedish Beräkningsmässigt skalar många av de klassiska metoderna inom spatiell statistik kubiskt med antalet observationer, vilket är opraktiskt om datamängderna är stora. I de traditionella tillämpningarna av statistik på spatiella datamänger begränsades ofta antalet observationer på grund av höga mätkostnader och metodernas beräkningskomplexitet inte sällan ett problem. NumerThe focus of this work is on the development of new random field models and methods suitable for the analysis of large environmental data sets. A large part is devoted to a number of extensions to the newly proposed Stochastic Partial Differential Equation (SPDE) approach for representing Gaussian fields using Gaussian Markov Random Fields (GMRFs). The method is based on that Gaussian Matérn fie

The soil salinity distribution and solute transport properties of three different soil types were investigated and compared within a project area in northeastern Egypt. For this purpose, dye tracer experiments and salinity sampling were carried out. The resulting salinity maps showed that the soil salinity in the cultivated western site of the project area is 8-10 times higher than that in the cul

The measurement of radioactive solutions containing organic or aggressive media may cause stability problems in liquid and plastic scintillation (PS) techniques. In the case of PS, this can be overcome by adding a crosslinker to the polymer structure. The objectives of this study are to synthesise a suitable crosslinked plastic scintillator (C-PS) for radioactivity determination in organic and agg

Organ segmentation on magnetic resonance (MR) images for dose planning on cancer patients is a time consuming process that can be automatized by using convolutional neural networks (CNNs). MR images vary greatly in characteristics across acquisition sites, which affects CNN segmentation performance. In this master thesis, augmentation methods were tested and implemented to increase the robustness

In this essay I attempt to examine corporations through the lens of postcolonial theory in order to investigate whether corporations and their actions can be better understood using a post-colonial analysis. I have investigated if we can understand corporations as transnational power structures rather than as only commercial businesses and what new perspectives that could give us. In my research I

It was a regular Thursday on October 28th in 2021 in the middle of the pandemic where humanity was going about in their everyday lives. However, Facebook CEO, Mark Zuckerberg had before witnessed a plethora of negative stories and reviews following the leak of Facebook ́s internal documents which portrayed the issues with the company. All of the negative press and political battles towards Faceboo

In this thesis, the relationship between people and places is investigated through examining how migrants in Vienna create place attachment to food markets in the city. A place attachment is understood as the emotional bond that forms between an individual and a specific space, the theoretical foundation of this thesis lies within emotional geography, a sub-field of human geography which examines

In response to the pressing need to address climate change and reduce global greenhouse gas (GHG) emissions, this study implemented Gaussian Mixture Models Clustering to detect the levels of GHG emissions and related socio-economic factors in 174 countries. To handle the panel data, Principal Component Analysis was conducted to achieve dimension reduction. Based on the algorithm, countries were gr

This paper investigates the moderating effect of employee skill, as measured by employee productivity and training, on the relationship between R&D spending, measured as R&D intensity, and firm performance, measured as ROA, for the accounting-based standard, and market capitalization, for the market-based standard. The study employs a hierarchical Pooled OLS logistic regression and a Fixed

At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater p

60 00 cancerfall rapporteras in varje år till socialstyrelsen men där numera fler än hälften botas. Detta eftersom vi blir skickligare inom området och nya behandlingstekniker utvecklas. Rektalcancer, även kallat ändtarmscancer är en cancerform som ökat under de senaste decennierna. Behandling av patienter med rektalcancer varierar beroende på var och i vilket stadie tumören befinner sig i. Oftast

Abstract Background: Person-centered care is increasingly regarded as being synonymous with best quality care. However, the concept and its precise meaning is a subject of debate, and reliable and valid measurement tools are few. This study is a part of a larger project named KUPA who´s main aim is to improve palliative care and person centeredness for elders living in nursing homes in two souther

This study explores the linguistic aspects of the jihadi culture and highlights the discursive role of classical Arabic within jihadism. It builds on literature on Jihadi culture and contributes to it by empirically analyzing the case of Islamic State linguistic traditions archeologically and genealogically. The study concludes that the use of classical Arabic constitutes one of the pillars of the

5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years. Signal processing techniques like

Using a microcontroller unit to implement different machine learning algorithms for myoelectric prosthesis control is currently feasible. Still there are hardware and timing constraints that need to be accounted for. This master thesis presents results from automatically generated Arduino code for some Neural Networks, Convolution Neural Networks and linear machine learning models that was impleme

EU har under de senaste åren satt upp målet att bli klimatneutral till 2050. För att nå upp till målet har EU-kommissionen identifierat att det behövs en massiv ekonomisk investering i hållbara ekonomiska aktiviteter runt om i EU. Denna omställning kan inte lösas utan stöd från privata investeringar och som en lösning på detta har EU-kommissionen infört EU:s gröna taxonomi som ska hjälpa entiteterThe EU has over the last few years set up the objective to become climate neutral by the year 2050. To achieve this objective, the European Commission has recognised the need for a massive transition investment into sustainable economic activities. The European Commission has also recognised that this investment cannot be done without the help of private funding which is why the European Commissio

Background. The United States has been a diverse country since it is establishment. The effects of socioeconomic characteristics including immigration, age, employment status, educational attainment on total fertility rate have been discussed in the previous studies. Objective. The objectives in this study are to explore whether the difference in the timings of first childbirth among Hispanic wome

Kunskap om markens uppbyggnad är viktig både för konstruktions och prospekteringsändamål. Geofysiska undersökningsmetoder kan användas för att skapa en överblick att basera vidare undersökningar på. I den här studien används likströms resistivitet och inducerad polarisation, IP. Datan är inverterad med en Cole-Cole modell i programmet ÅrhusInv och använd för att karakterisera berggrunden vid ÖnnesFor both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. In this study direct current resistivity and induced polarization data, inverted with a Cole-Cole model in program AarhusInv, are used to characterize the bedrock at Önneslöv in Scania,
