Inflationen har stigit kraftigt de senaste åren runt om hela jorden. Stigningen kom oväntat och överraskade både centralbanker och kapitalförvaltare. Detta har lett till kraftiga ränteökningar för att försöka dämpa inflationen till lägre nivåer. Kanske hade det gått att undvika dessa kraftiga ränteökningarna om man hade haft tillgång till estimat av inflation på förhand. Vi undersöker i detta exDifferent models were developed with the aim of nowcasting inflation at a daily basis with high frequency variables, while using real-time data to avoid look ahead bias. Both popular machine learning models such as Random Forest and XGBoost, and more traditional models such as UMIDAS and Almon distributed lag models were used to make the nowcasts. The MIDAS framework was utilized as a way of handl

At the Children’s Heart Center of Skåne University Hospital (BUS) there is an ongoing project with live recordings of open heart surgeries. These recordings will be used for educational purposes, for planning of future surgeries, as well as for evaluating the surgical procedures. Currently, the recordings are made using two cameras that are positioned above the operating table on a temporary mount

Easy exposure of biological particles for molecular stimuli is of interest when examining the effects of antibiotics on different bacteria or to perform toxicity analysis for biophysical studies of vesicles. Such experiments require advanced equipment that can only be found in laboratories and are vastly time-consuming. A possible solution to the problem could be a “lab-on-a-chip”, which in short

Voice impersonation is a technique that has often been used by criminals whose goal is to avoid being identified while committing a crime. There are, however, other interesting cases where the police confronts a suspect with an incriminating recording, and the suspect would deny being the true speaker in that recording, and claim that it belonged to an expert impersonator. In both of these cases,

Judith Butler’s gender theory examines gender as a social construct that is created and reproduced by societal structures. Stuart Hall’s representation theory also centers around this idea, but rather concerning how media images both create and are created by a historical, cultural and political context and therefore changes and reproduces a specific way of viewing our society. This thesis, then,

This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals

In recent years, businesses have been focusing on Customer Lifetime Value (CLV) to achieve better customer relationships and to identify high-value customers for more customized marketing strategies. This thesis contributes by comparing the performance of different machine learning models on cluster-specific data points and the complete dataset from the auto insurance industry. In addition, the st

The basis of this thesis is the exit problem in close corporations and the protections available to the minority. The phase one of the problem is when oppression takes place, which includes actions when dividends are withheld and excessive bonuses are paid to the majority, leading to the unfair treatment of the minority. Phase two of the problem is the exit problem itself, the minority owner's

In October 2008, the Swedish government made a resolution about a testing period for advanced classes in some of the Swedish high schools. After about a year the Swedish minister of education, Jan Björklund, made a statement that he wished that the try with the so called elite classes be extended to the primary schools. The purpose of my paper it to analyse the Swedish debate about elite classes i

This work presents a rule-based character-recognition system for the Korean script, Hangeul. An input raster image representing one Korean character (Hangeul syllable) is thinned down to a skeleton, and the individual lines extracted. The lines, along with information on how they are interconnected, are translated into a set of hierarchical graphs, which can be easily traversed and compared with a

The purpose of this thesis was to develop and design a new machine for fatigue testing of bicycles. It was carried out for and in close cooperation with Svensk Maskinprovning AB, The Swedish Machinery Testing Institute. The machine was to test certain bicycle components according to a new standard of certification, valid in the entire EU. The goal was to attack the problem as openmindedly as possi

We study how processing states alternate during information search tasks. Inference is carried out with a discriminative hidden Markov model (dHMM) learned from eye movement data, measured in an experiment consisting of three task types: (i) simple word search, (ii) finding a sentence that answers a question and (iii) choosing a subjectively most interesting title from a list of ten titles. The re

In recent years, the 'river basin as a management unit' approach has been adopted as a solution to water management. The situation between Swaziland, Mozambique and South Africa regarding managing the water resources of the Incomati, Maputo, and Umbeluzi shared river basins is an interesting case that might need a different approach. These rivers flow downstream to the Maputo estuary where their w

Context: Magnetic resonance imaging (MRI) combined with magnetic resonance spectroscopy imaging (MRSI), dynamic contrast-enhanced MRI, and diffusion-weighted MRI emerged as promising tests in the diagnosis of prostate cancer, and they show encouraging results. Objective: This review emphasizes different functional MRI techniques in the diagnosis of prostate cancer and includes information about th

The plan for the final disposal of spent fuel front Swedish nuclear power plants is to place it in copper canisters that are sealed and stored in a deep repository. The canisters will be sealed by friction stir welding (FSW) and the reliability of this process has now been evaluated. The reliability study was performed in three steps: first an optimization experiment to identify optimal process se

Arrhythmic mammals are active both during day and night if they are allowed. The arrhythmic horses are in possession of one of the largest terrestrial animal eyes and the purpose of this study is to reveal whether their eye is sensitive enough to see colours at night. During the day horses are known to have dichromatic colour vision. To disclose whether they can discriminate colours in dim light a

Jönköping stad har stora framtidsambitioner och hoppas på att staden kan växa i samband med att den nya höghastighetsjärnvägen byggs. För att klara av nya invånare och uppnå de kommunala och transportpolitiska målen behöver kollektivtrafiken byggas ut. Den nuvarande busslinje 1 som är den mest trafikerade linjen i Jönköping idag behöver dras om vid vissa delar för att inkludera den nya höghastigheJönköping city has big ambitions for its future, and they hope that the city can grow with the new highspeed railway. To manage all the new citizens and make up for the communal and transport political goals they need to expand their community rides. Today’s bus line 1, which is the most trafficked line in Jönköping, need a reroute to include the new station for the highspeed trains which will be

Innovation is essential in our technological society. There exist a large number of innovative companies in the world, however, still there is a great scope for many others to join and take advantage of this treasure that have caused success for many organizations. There are a growing number of authors in the field of innovation, that have a mount of articles about innovation, innovation managemen
