2	Investigation of feature selection optimization for EEG signal analysis for monitoring a driver Danielsson, Stefan January 2015 (has links) Electroencephalogram (EEG) is a well known, and well used method for studying brain activity, and it's possibilities have lately stretched into the car industry, were it's capabilities of detecting sleepiness in drivers are currently being put to the test. When performing EEG signal analysis on the brain, standardized signal bands exists that are characteristic to specific states of mind, such as when a driver is feeling sleepy. However, EEG as a method for studying the brain has major problems. The signal contains a lot of information that can be redundant or irrelevant, and the result is easily influenced and deviant by other parameters, that can cause incorrectness and inaccuracy in the final prediction and classification of the signal frame. One of the important methods for reducing this inaccuracy of EEG, and also reducing the computational cost of the diagnose, is feature selection. Finding key features in the signal, that can support a reliable diagnosis of a specific state of mind, is of great importance. Especially since learning systems, incorrectly predicting or interpreting a signal in the classification stage, can lead to incorrect triggering of safety features in futuristic cars, such as cruiser control. There are many existing feature selection algorithms available, and features that has been tried in different research project. The goal of this research was to help gather more accurate inputs from EEG, through an optimization study, and to increase the reliability of EEG. And by doing so, hopefully improve safety systems in cars, that in turn could help preventing sleepiness-related accidents on roads in the future. This was realized through a study of features, and feature selection algorithms. By determining key features that could distinguish sleepiness from a signal, as well as performing accuracy tests for different feature selection algorithms, the motivation for an optimal selection, based on the used parameters, could be made. However limited this research was, it concluded that Information Gain as a method for selecting features, was the most accurate algorithm, and that some features were better to use then others, such as Huguchi's fractal dimension, and the Hjorth complexity.

3	Upp till kvinnokamp : Skildringen av arbetarklassens kvinnor i konsten / Up to women's fight : The portrayal of working-class women in art Björk, Anna January 2022 (has links) Throughout history men and women have not always been given the same opportunities to work. As a result of prevailing politics and norms, women have been relegated to household chores. To portray women and the working-class in the same picture can therefore be contradictory - how do you portray the working-class through those who do not work? The aim of this study is to explore, with help from Panofsky’s iconology as a method for image analysis, how women from the working-class are being portrayed in art. The study is focused on artworks made by a group of Swedish artists active during the first half of the 20th century. The group’s main motifs were the working-class and social injustices, and they used their art as a form of activism against the ongoing world war, capitalism and patriarchy. Common for the portraits of women by all of the artists is that they portray women as housewives and mothers. Explanations for this are searched, and found, in Ulla-Britt Tillman’s theory about women as a motif in working-class art and Laura Mulvey’s Male gaze theory.

4	Metody rychlého srovnání a identifikace sekvencí v metagenomických datech / Methods for fast sequence comparison and identification in metagenomic data Kupková, Kristýna January 2016 (has links) Předmětem této práce je vytvoření metody sloužící k identifikaci organismů z metagenomických dat. Doposud k tomuto účelu spolehlivě dostačovaly metody založené na zarovnání sekvencí s referenční databází. Množství dat ovšem s rozvojem sekvenačních technik rapidně roste a tyto metody se tak stávají díky své výpočetní náročnosti nevhodnými. V této diplomové práci je popsán postup nové techniky, která umožňuje klasifikaci metagenomických dat bez nutnosti zarovnání. Metoda spočívá v převedení sekvenovaných úseků na genomické signály ve formě fázových reprezentací, ze kterých jsou následně extrahovány vektory příznaků. Těmito příznaky jsou tři Hjorthovy deskriptory. Ty jsou dále vystaveny metodě maximalizace věrohodnosti směsi Gaussovských rozložení, která umožňuje spolehlivé roztřídění fragmentů podle jejich příslušnosti k organismu.
5	EEG-Based Estimation of Human Reaction Time Corresponding to Change of Visual Event. January 2019 (has links) abstract: The human brain controls a person's actions and reactions. In this study, the main objective is to quantify reaction time towards a change of visual event and figuring out the inherent relationship between response time and corresponding brain activities. Furthermore, which parts of the human brain are responsible for the reaction time is also of interest. As electroencephalogram (EEG) signals are proportional to the change of brain functionalities with time, EEG signals from different locations of the brain are used as indicators of brain activities. As the different channels are from different parts of our brain, identifying most relevant channels can provide the idea of responsible brain locations. In this study, response time is estimated using EEG signal features from time, frequency and time-frequency domain. Regression-based estimation using the full data-set results in RMSE (Root Mean Square Error) of 99.5 milliseconds and a correlation value of 0.57. However, the addition of non-EEG features with the existing features gives RMSE of 101.7 ms and a correlation value of 0.58. Using the same analysis with a custom data-set provides RMSE of 135.7 milliseconds and a correlation value of 0.69. Classification-based estimation provides 79% & 72% of accuracy for binary and 3-class classication respectively. Classification of extremes (high-low) results in 95% of accuracy. Combining recursive feature elimination, tree-based feature importance, and mutual feature information method, important channels, and features are isolated based on the best result. As human response time is not solely dependent on brain activities, it requires additional information about the subject to improve the reaction time estimation. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2019 Electrical engineering Psychology brain-computer interface electroencephalogram (EEG) Hjorth parameters machine learning reaction time estimation spectral analysis
6	Axel Einar Hjorth – arkitekten som glömdes bort : om Nordiska Kompaniets chefsarkitekt och svensk art déco / Axel Einar Hjorth – the architect who was forgotten : an essay about the head architect of Nordiska Kompaniet and Swedish art déco Carlsten, Susanna January 2008 (has links) Denna uppsats beskriver möbelarkitekten Axel Einar Hjorths karriär och produktion med fokus på åren 1927-32, hans första sex år som chefsarkitekt på Nordiska Kompaniet. Genom att undersöka några samtida tidskrifter försöker uppsatsen även utröna hur Hjorth mottogs under sin egen tid, samt varför han var förtigen i svenskdesignhistoria så länge. I uppsatsen ingår flera möbelanalyser vilka syftar till att beskriva Hjorths stil och bredd samt tidens smak. Uppsatsen visar att Axel Einar Hjorth ofta ritade internationellt orienterade möbler i ren art déco, men också stilmöbler, funktionalistiska seriemöbler m.m. Art déco var en stilriktning under mellankrigstiden, men i Sverige talar vi ofta om ”Swedish Grace” eftersom mycket konsthantverk under denna tid fick ett något svalare klassicistiskt uttryck än övriga länders. I Sverige har art décon eller ”Swedish Grace” ofta hamnat i skuggan av funktionalismen, som fick större genomslagskraft. Det är en av anledningarna till att ingen akademisk text tidigare har skrivits om Axel Einar Hjorth. / This essay describes the carrier and production of the architect Axel Einar Hjorth, with an emphasis on the years 1927-1932, his first six years as head architect at Nordiska Kompaniet. The essay also tries to inquire into how Hjorth was recieved by contemporary press and explain why he was forgotten about for many years. The study shows that the furniture designs of Axel Einar Hjorth was very international in it´s style. Instead of calm classicism the furnitures often have strong references to art déco, a style that didn´t grew big in Sweden. The essay includes several furniture analyses where the aim is to show Hjorths versatility. Hjorth designed both art déco furnitures, period furnitures and more modernistic furnitures etc. One of the reasons why so little has been written about Axel Einar Hjorth and art déco in Sweden is that the funktionalism won the debate with it´s socialistic ideas, which made art déco a short-lived style.

7	Obraz a proměny společenské kritiky ve vybraných dílech švédské detektivky / The image and transformation of social critique in selected works of Swedish Crime Fiction Všetečková, Andrea January 2020 (has links) (in English): The thesis deals with the topic of social criticism across the genre of detective stories from the 1960s in Sweden. The theoretical part describes how social criticism is constituted in this genre and how it contributes to its specificity. Based on a selected cross-section of five works, it presents not only the various topics which these authors work with, but also the changes in this critique over time. The analyzed works are: The Man on the Balcony (1968) by Sjöwall and Wahlöö, who establish this genre with clear social criticism, the first part of the trilogy Millennium The Girl with the Dragon Tattoo (2008) by Stieg Larsson, who, according to many experts, successfully completes this era, The Stone Cutter (2008) by Camilla Läckberg, The Sandman (2012) by Lars Kepler and Those Who Failed (2015) by the duo Hjorth and Rosenfeldt, that is the works by three contemporary authors of this genre.

The homes that were chosen for the study are Tallbo, in the region of Gästrikland, the home of Swedish painter Ecke Hedberg (1868-1959) and Bror Hjorths Hus in the city of Uppsala, the home of Swedish painter and sculptor Bror Hjorth (1894-1968). The essay focuses on the permanent exhibitions of the artists private homes and ateliers, and the interior and artworks that are shown. This essay answers the questions of which objects have been chosen for the exhibitions (with a presentation of the interior and art in both homes), how the objects are organized and curated, how the objects are presented and in which public context the exhibition functions in. The latter question is answered within the frame of intermediation, musealization, cultural heritage and identity connected to Australian historian and curator Linda Young’s theories of historical homes. / I denna studie undersöks och jämförs två svenska musealiserade konstnärshem utifrån en tillämpad användning av den danske konsthistorikern Rune Gades metod för utställningsanalys. Konstnärshemmen som valts ut för studien är Tallbo i Gästrikland, hem till konstnären Ecke Hedberg (1868-1959) och Bror Hjorths Hus i Uppsala, hem till konstnären och skulptören Bror Hjorth (1894-1968). Fokus ligger på interiören och konstverken i de permanenta utställningarna. Studien svarar på frågor som rör vilka objekt som valts ut för utställningarna, hur föremålen är organiserade, hur föremålen är presenterade och i vilken offentlig kontext som utställningarna fungerar. Detta besvaras utifrån perspektiv som förmedling, musealisering, kulturarv och identitet kopplat till den australiensiska historikern och curatorn Linda Youngs teorier om historiska hem.
