We apply neural networks and random forest to study geological data. In part one of the thesis, a ground water level prediction task is performed with recurrent neural networks, random forest and vector autoregression. The input data consists of weather data and other ground water level time series. The MAE and R-squared is evaluated and the variation in performance of the neural networks is discu

To fully decarbonise the energy system, electrification is needed as one of the most important strategies for reducing carbon dioxide emissions in Sweden and Europe. The deployment of renewable energy resources plays a central role in electrification and will continue to increase. In January 2024, Svenska Kraftnät published a long-term market analysis with four future scenarios regarding the devel

Background: Cognitive assessment for foreign-born individuals is suboptimal. The Multicultural Cognitive Examination (MCE) was developed for use in culturally, linguistically and educationally diverse populations. The MCE includes the Rowland Universal Dementia Assessment Scale (RUDAS) and performs assessment of memory, verbal fluency, and visuospatial function. Objective: To compare the psychomet

Background: Geraniol is a widely used fragrance terpene, and is included in fragrance mix I. Geraniol is prone to autoxidation, forming the skin sensitizers geranial, neral, and geraniol-7-hydroperoxide. Oxidized geraniol has previously been patch tested in 1 clinic, giving 1% to 4.6% positive reactions in consecutive patients when tested at 2% to 11%. Aim: To compare test reactions to pure and ox

Objectives There is evidence that emergency department (ED) crowding is associated with increased mortality, however large multicenter studies of high quality are scarce. In a prior study, we introduced a proxy-measure for crowding that was associated with increased mortality. The national registry SVAR enables us to study the association in a more heterogenous group of EDs with more recent data.

In a study by Brent Berlin & Paul Kay from 1969 it was found that there are 11 basic color terms and 7 stages of color evolution. Since then, there have been many follow-up studies within the field to confirm or deny this finding. Some have argued against only including 11 terms in the category of basic while others have criticized the criteria they used for basicness. Some have proposed that

The initial part of this paper presents an overview of research conducted on switching costs and their implications. Different types of switching costs are identified and categorised according to available research and examples are given. Further, switching costs are with the help of previous research put in relation to various business actions we may encounter on an everyday basis and how they af
