MOx sensors are widely used for sensing gases. In this thesis a variable temperature MOx sensor was used to detect graffiti spray paint and differentiate it from other substances using the sensors sensitivity to different gases at different temperatures using machine learning. The machine learning methods Support Vector Machines, k-Nearest Neighbour and neural networks were evaluated and compared.

Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. The first network uses the Morlet wavelet transform to achieve adaptable f

Twitter took off as a political tool with the 2016 election and it became a space for personal attacks directed to and between politicians. This study focuses on the Squad, four female politicians representing minorities and their use of Twitter in the months before the US election of 2020. The focus is on political semantic violence with Krook’s theory used for analysis. Burke’s identity theory i

Under min tid som arkitektstudent har jag lärt mig att arkitektur handlar om att arbeta med representationer; hur en fysisk form gestaltas med en inneboende kommunikationsförmåga. Arkitektur verkar genom den mänskliga perception av ett observerat fenomen, inom den sfär där människan relaterar till den fysiska formen. Ämnet arkitektur befinner sig i gränslandet mellan människan och formen. I mittDuring my time as a student of architecture I’ve learned that architecture is about working with representations; how a physical form is shaped with an inner ability to communicate. Architecture operates in the perception of an observed object, within the realm where humans relates to the physical object. The subject of architecture is situated between the physical form and the human experience.

Det förekommer i dagsläget att det bildas tillfälliga fastigheter för exploateringsändamål. Anledningen till att de bildas är att exploatören vill få lagfart och möjlighet att belåna fastigheten tidigare, i jämförelse med att exempelvis vänta tills det att hela området har genomgått en slutgiltig fastighetsbildning för t.ex. bostadsfastigheter. Trots sina fördelar hindras denna fastighetsbildning This dissertation aims to analyze the suitability of formation of development properties and to investigate when and under what circumstances this property formation can be accomplished. These properties are for temporary purposes and facilitate a more simple property formation in the future. The possibility of obtaining the ownership over the property and to mortgage the property usually triggers

Sitting in a high chair gives a feeling of security and of having control - you get an overview of the room you are in. But high chairs are often difficult to get up on, you feel clumsy, there is no good support for your feet and they are often quite uncomfortable. The research I have done shows that many people therefore reject the high chair, despite the positive feelings it can also give. Thos

Boken Omgiven av idioter och DISA/DISC-modellen som ligger till grund för boken har väckt stor debatt i Sverige. Samtidigt som personlighetstester baserade på modellen har stor spridning anklagas den för att sakna vetenskapligt stöd. I den här uppsatsen gör jag en pragmadialektisk analys av debatten kring modellens vetenskaplighet. Jag analyserar dels hur Thomas Erikson, författaren till Omgiven a

During the production of Axis's cameras, the optics modules have to do a number of tests and calibrations that are performed in different test stations. The test and calibration sequence differs between different models. This has so far been done manually by having operators move the units between test stations. However, Axis are planning to automate the procedure by having an industrial robot

Arkitektur i samarbete är ett examensarbete som undersöker ett samarbete med en scoutkår och beskriver en gestaltningsprocess i detalj. Scouting är en rörelse som bygger och examensarbetet är på så sätt även ett utforskande i scoutbyggande. Hur kan arkitekter beskriva processen fram till en byggd form istället för den byggda formen? Vad kan vi lära oss av beskrivningen av processen? En önskan i e

This research paper analyzes the effect of growing environmental concern on home bias in the European Union. Using the latest release of the International Trade and Production Database for Estimation, for the years 2002-2016, the home bias is estimated with the gravity model of trade. The Eurobarometer “Public Opinion in the European Union” is used as a proxy for environmental concern over the sam

The purpose of this thesis is to discuss which approach and mindset is most optimal when creating a recording as a classical musician. This thesis examines and compares the differences between the practise of creating a recording and live performance predominantly from the perspective of the performer. Firstly, a review of literature from the field is made followed by a reflection of my own person

The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. Despite restoration projects already being i

Den mänskliga hjärnan är ett anmärkningsvärt organ som formar våra mest komplexa tankar och medvetande. Ändå består den huvudsakligen av två typer av vävnader och en vätska, d.v.s. vit vävnad, (WM), grå vävnad (GM) och cerebrospinalvätska (CSF). Vit substans finns framför allt i de segment i centrala nervsystemet (CNS) som består av myeliniserade axoner och möjliggör långväga kommunikation mellan Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle. From this MP2RAGE signal, the underlying T1 relaxation

Uppsatsen undersöker huruvida Riksbankens utförande av kvantitativa lättnader mellan 2015 och 2018 har haft signifikanta effekter på inkomstfördelningen i Sverige. Två potentiellt inkomstfördelande kanaler studeras genom en serie av panelregressioner på decilindelad data över kapital – och arbetsinkomster i Sverige mellan 1995 och 2018. Undersökningen finner inget bevis för en inkomstutjämande kan

This paper employs a zombie classification following (Storz et al., 2017) to examine the phenomenon of zombie firms and low interest rates in Denmark using a comprehensive harmonized firm-level micro dataset from ORBIS covering the period 2002-2019. Specifically, the questions addressed are whether the prevalence of zombie firms increased due to low interest rates and has surviving as a zombie bec

This thesis investigates how Vicke Lindstrand’s public sculpture Legend i glas, located in Teaterparken in Växjö, can be related to its location and spatial context in terms of meaning, function and reception. Central questions asked are: How do changes in the direct surroundings affect the situation of reception? How does that affect the meaning and function of the sculpture? To what extent is me

Den första delen av denna uppsats analyserar den språkliga kvaliteten i ett urval av informationstexter från statliga myndigheter, regioner och kommuner. Den andra delen studerar sambandet mellan språklig kvalitet och hur informationenMost authorities in Sweden provide an English language version of their web sites, in the form of a translation or an adaptation of the Swedish original text. The first part of this thesis includes an analysis of the linguistic quality of a selection of texts from authorities on three administrative levels: state, regional and municipal. The second part investigates the correlation between linguis

Context: Urban air pollution is considered a significant factor contributing to increased respiratory and cardiovascular mortality in cities. Many studies focused on the relationship between exposure to diesel exhaust and human health effects, demonstrating the toxicity of such gases. Biodiesel is described as a more carbon-neutral alternative to petroleum derivatives, but few studies have been co

The generation of phenotypes in nature is not boundless. They are governed by natural selection as well as genetic and developmental processes that precede selection. When the developmental process itself is biased, it promotes or prevents certain phenotypes from being formed which in turn could impact the course of evolution. Despite the solid theory behind developmental bias, its exact influence

The Role of UCHL3 in Malignant Melanoma Malignant melanoma is the deadliest types of skin cancer that originates from skin pigment (melanin) producing cells named melanocytes. It is known that ultraviolet (UV) radiation is one of the major sources for causing melanoma via damaging the cellular machinery. During the process of primary tumor progression into the metastatic form, a series of molecul
