This study has been performed with a quantitative method with a deductive approach for an analysis of

Vi har alla stått alldeles för länge i en kö för att handla den där chipspåsen, lunchlådan eller lördagsgodiset. Att handla mat är ett måste för oss alla, och de flesta av oss föredrar att få det överstökat så snabbt som möjligt. Detaljhandeln erbjuder snabbkassor, men nu är det dags för nästa steg, helt automatiska lösningar som använder den senaste tekniken inom datorseende och artificiell intelIn recent years advances in computing power, availability of large annotated datasets and AI algorithms have enabled the rise of reliable object identification and tracking. This thesis describes the development and implementation considerations of a system for object detection in the retail industry. This project have been conducted as a collaboration between ETH Zürich and start-up company AI Re

Denna studie undersökte sambanden mellan individers personlighetsdrag och individers nivå av hemberedskap, vilket innebär i vilken utsträckning individer är benägna att förbereda sig inför en eventuell kris som påverkar samhällsfunktioner. För att ge ytterligare en dimension till studien undersöktes även individers världsbild i relation till personlighetsdragen. De undersökta faktorerna var de tre

This thesis concerns early medieval dress brooches from urban and rural sites in South West Scania. The purpose is to investigate similarities and differences between urban and rural sites as well as between the rural places in particular. The main research questions concern the reasons for the similarities and differences, what connections and contact areas are observable according to the dress b

With the present thesis I aim to explore what accounts for fluctuations in capital formation and profitability in Sweden and the UK since 1950. Do expectations rule investments which in turn determine profits, or is it rather profitability that rule expectations and thus investment behaviour? Applying a finite distributed-lag model on a variety of variables, profits emerge as a reliable key factor

Föreställ dig att det går att förutse vistelsetid och överlevnad inom 30 dagar för en patient som läggs in på en intensivvårdsavdelning. Dessa mått kunnat bidra till en djupare förståelse för intensivvård. Dessutom hade dörrar öppnats för jämförelse av vårdavdelningar sinsemellan. I det här projektet har intagningsdata till intensivvårdsavdelningar, in- nehållande allt ifrån information om kroppstA large data set, consisting of 300 000 patients’ admission data to various intensive care units in Sweden, acquired from the Swedish Intensive Care Register, was used in this work. The aim was to enable accurate Length of Stay (LOS) and mortality within 30 days predictions by using feed-forward Artificial Neural Networks (ANNs). The LOS outcome was predicted as short versus long time stays, with

This research draws a parallel between the recent political backlashes witnessed in the (de)-industrialized world and people’s attitudes towards climate policies. In lieu of the rise of populism, subjective feelings induced by individuals’ perceptions of their condition have increasingly been considered by researchers. In parallel, there is a substantial literature on the determinants of public su

Vår stjärna solen är långt ifrån den enda i universum. Det finns enorma mängder stjärnor bara i vår egen galax. Man har upptäckt att en stor andel av av stjärnor existerar i binära par, det vill säga två stjärnor som kretsar kring varandra. Dessutom har nya observationer med hjälp av KEPLER teleskopet under 2010-talet har visat vad man endast har kunnat spekulera om i flera årtionden: planeter kanThe observations of circumbinary planets have confirmed that these can in fact be stable. While previous studies on circumbinary planets have been done, not many have been made on systems containing multiple circumbinary planets on eccentric orbits. In this thesis, the effects a binary star system of solar mass would have on the Solar System is investigated. Using the program MERCURY, numerous int

In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization. Describing turbo equalization in the perspective of message passing on factor graphs, we show various

Problem solving skills are highly related to later life success. Several factors can influence these skills and their development, for example the level of executive function (EF) as well as individual temperamental features. This study examined problem solving performance among young (22-60 months old) children in a cross sectional design. The aim of the study was to explore how different compone

The purpose of this study is (1) to investigate the direct influence of femvertising on female consumers’ attitudes towards the ad, brand gender perception as well as purchase intention and (2) to test the indirect effect of femvertising through attitudes towards the ad and brand gender perception on purchase intention. This study used a random independent group design, assigning the survey respon

Studien granskar de kontrasterande bilder av Karl Marx teorier och marxismen som ges av sociologiutbildningar på svenska universitet. Genom intervjuer med undervisande sociologer och en litteraturstudie över den vanligaste introduktionslitteraturen visar jag några centrala skiljelinjer inom sociologin. En riktning främst representerad av Anthony Giddens & Philip W. Suttons bok Sociologi (2014)This study reviews the contrasting images of Karl Marx theoretical output and of Marxism offered by sociology courses at Swedish universities. By means of interviews with lecturing sociologists and a literature review covering the most common introductory textbooks I demonstrate some central dividing lines within sociology. One tendency is foremost represented by Anthony Giddens’ & Philip W. S

Hypothyroidism is a common disease involving diverse physical, cognitive, and emotional symptoms impacting many aspects of functioning. The indicated treatment produces significant improvements but leaves many with residual symptoms that significantly impair functioning. Numerous patient surveys reveal high levels of dissatisfaction with the treatment and healthcare professionals. Less well unders

Examensarbetet ämnar att utvärdera användning samt utveckling av en "intelligent uppvärmning" för ett hus. Genom att kontrollera strömbrytare, kopplade till en säkring, kan olika tekniker som kan användas för en självlärande algoritm utvärderas. För tillfället måste användarna själva försöka förutsäga hur lång tid en uppvärmning kommer att ta. Den utvecklade algoritmen ska hjälpa användaThis report aims to examine the use and development of a more intelligent heating process in a house. By controlling switches integrated into a fuse, the techniques that can be used to allow an algorithm to predict how long the heating process would take are evaluated. Currently users have to, themselves, estimate how long the heating process will take. The algorithm developed aims to alleviate th

Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. Tundra ecosystems are particularly important to study these effects due to short growing seasons, poor pollinator community and a particularly pronounce

Operant conditioning is a psychological theory about learning through positive and negative reinforcement which has been researched for decades. However, some fundamental components of this theory have not yet been thoroughly researched, such as its interaction with long-term retention and context. These components are essential if we want to understand how operant conditioning applies in everyday

The aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. Because of the high numerical complexity of GPs, sparse approxi
