1. 1. Do Changes in Housing Prices and Rents Affect Fertility Decisions? A panel data study on women aged 20-45 in Switzerland.

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Eric Hermansson; Kristóf Surányi; [2024]
   Keywords : Fertility decisions; Housing prices; Switzerland; Wealth effect; Cost effect;

   Abstract : The following paper was carried out to investigate the effect of changes in housing prices and rents on fertility decisions. More specifically, by observing owners and renters of housing in Switzerland during 1999-2019. READ MORE

3. 2. Energy efficiency and fiscal incentives : A stochastic frontier analysis of Swedish manufacturing sectors 2008-2020

   University essay from Umeå universitet/Nationalekonomi

   Author : William Blombäck; [2024]
   Keywords : ;

   Abstract : This thesis is a case study of the Swedish manufacturing industry in which I measure how efficiently each sector uses energy (fuel and electricity) as input goods in their production processes, and how significant the impact of Sweden’s energy tax is in regard to energy efficiency. The purpose of this is to analyze energy security and preparedness for short-term demand shocks for electricity, as many ‘mega-investments’ of industrial nature are being planned in Sweden – which are predicted to require the installed capacity of Sweden’s electricity production to almost double by 2045.

4. 3. An Empirical Survey of Bandits in an Industrial Recommender System Setting

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Tobias Schwarz; Johan Brandby; [2023-09-21]
   Keywords : computer science; industrial application; machine learning; reinforcement learning; multi-armed bandits; MAB; contextual multi-armed bandits; survey; batch learning;

   Abstract : In this thesis, the effects of incorporating unstructured data—images in the wild—in contextual multi-armed bandits are investigated, when used within a recommender system setting, which focuses on picture-based content suggestion. The idea is to employ image features, extracted by a pre-trained convolutional neural network, and study the resulting bandit behaviors when including respective excluding this information in the typical context creation, which normally relies on structured data sources—such as metadata.

5. 4. Analyzing the performance of active learning strategies on machine learning problems

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Vendela Werner; [2023]
   Keywords : computer science; bioinformatics; machine learning; active learning; artificial intelligence; supervised learning; Astrazeneca; maskininlärning; artificiell intelligens; datorvetenskap; active learning; bioinformatik; supervised learning;

   Abstract : Digitalisation within industries is rapidly advancing and data possibilities are growing daily. Machine learning models need a large amount of data that are well-annotated for good performance. To get well-annotated data, an expert is needed, which is expensive, and the annotation itself could be very time-consuming. READ MORE

6. 5. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Erik Nordlund; [2023]
   Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

   Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. READ MORE
