Lund University have for over ten years been using a website called LUP Student Papers where they publish theses from bachelor and master courses. The aim of this thesis is to use visualizations and data mining techniques that will explore and shows interesting aspects of the data. The wide variety of variables in the dataset can be used to gain insight regarding several interesting questions such
Genom en socialsemiotisk multimodal analys tillsammans med en queerteoretisk ansats syftar denna uppsats till att ge nya insikter till fältet för strategisk kommunikation, marknadsföring och icke-stereotypisk reklam. Reklam har länge använt sig av stereotypa framställningar vilket är problematiskt eftersom det bygger på generaliserande antaganden av personer och grupper. Eftersom reklam har stor m
This bachelor’s dissertation is written by Allis Stenvall and Isabella Österlund (2020), Division of Fashion Science, Lund University. The study titled “Dismantling the creative director” - A media content analysis of creative directors Daniel Lee and Simon Porte Jaquemus aims to analyze and understand the expectation and definitions of a creative director at a luxury fashion house and what influe
In induction heating processes with complex workpiece geometries or stringent requirements, more than one induction coil is usually needed to obtain acceptable results. One objective could be to achieve uniform heating, with minimal temperature variations throughout the workpiece. One frequency converter for each induction coil could be used, but it would not be cost-effective, and instead, it is
Vätgas är en energikälla som har en energidensitet (per massa) tre gånger så stor som naturgas. Detta gör så att vätgas är en huvudkandidat för morgondagens bränsle. Ett av de viktigaste forskningsområderna för vätgas innefattar produktion av vätgas eftersom det finns en stor mängd metoder för vätgasproduktion. Återvinnbar vätgas kan potentiellt produceras med vattenelektrolys, som undersöks i detHydrogen gas is an energy source that has an energy density (per mass) that is three times as large than the energy density of natural gas. This qualifies hydrogen gas as a prime candidate for the fuel of tomorrow. One of the main research areas for hydrogen include the production of it as there are a vast amount of methods of hydrogen production. Renewable hydrogen can potentially be produced thr
I Sverige har flertalet naturolyckor inträffat genom tiderna och det är även idag vanligt med olika typer av naturolyckor. Dessa förväntas i framtiden inträffa mer frekvent och bli allt mer omfattande till följd av klimatförändringarna. Naturolyckor kan kategoriseras som geologiska, biologiska och hydrometeorologiska. Den sistnämnda är väderrelaterade olyckor och i många fall blir den kommunala räIn Sweden, natural disasters have been occurring for many years and will continue to do so in the future. Not all types of natural disasters are possible in Sweden. This thesis will therefore focus on natural disaster that are more likely to occur in Sweden, based on previous incidents and predictions for the future, namely forest fire and floods. In this thesis, an investigation of municipal Fire
Unmanned vehicles need robust systems to ensure the safety of the vehicle and its environment. Being able to find and avoid perilous situations is paramount to such a system. In this paper we suggest an unsupervised image-based anomaly detection algorithm using a variational autoencoder and a superpixel segmentation algorithm, which is adapted to the maritime obstacle detection task. The algorithm
Although reinforcement learning has gained great success in computer games, there are only few yet known implementations in ndustrial applications. This despite the fact that reinforcement learning offers interesting methods to optimise the control of nonlinear processes. In this thesis we have used two model free reinforcement learning algorithms (PPO and DDPG) to control three different simulati
In this thesis, a study is made into relative positioning and control systems for flying wing Micro Aerial Vehicles (MAVs) intended to be used by the Swedish Sea Rescue Society (SSRS) for the purpose of providing assistance during sea rescue missions. The particular scenario of interest is robust relative positioning to be used for autonomous landing of a MAV on a boat at the end of a rescue missi
Evaluating suppliers is something that the majority of companies has to do and is something that often is a complex problem with many parameters and variables involved. This is especially true for a company like Kiviks Musteri that purchases a variety of different products from all over the world from different types of suppliers that come from different cultures and backgrounds. It is also essent
The world has been affected by a pandemic virus called SARS-CoV-2 and caused a high level of deaths. Does the level of relative humidity have an effect on the spread? Different levels of the relative humidity has different affection on humans from a medical aspect. Is there an optimal level of the relative humidity? In this report there is a study on how the level of relative humidity indoor affec
Abstrakt Bakgrund: I takt med att förlossningsvården centraliseras och avståndet till förlossningsavdelningar ökar kommer ambulanssjuksköterskor troligtvis att behöva assistera vid fler prehospitala förlossningar. Med begränsad utbildning och erfarenheter kan sådana situationer upplevas stressande. Syfte: Att undersöka ambulanssjuksköterskors upplevelser och erfarenheter av prehospitala förlossnin
Bakgrund: En del av uppdragen som ambulanssjukvården utför handlar om olyckor, skador eller akut sjukdom som sker i offentlig miljö. Detta innebär att det vårdande utrymmet delas med allmänheten. För sjuksköterskan innebär detta en utmaning. Genom att studera sjuksköterskors upplevelser av att vårda i offentlig miljö kan det skapas ökad förståelse för sjuksköterskors situation i ambulanssjukvården
Bakgrund: hot, våld och misshandelsbrott mot barn under 18 år har blivit ett mer förekommande problem i det svenska samhället med ökat antal orosanmälningar. Hälso- och sjukvårdspersonal ska enligt socialtjänstlagen anmäla om barn misstänks/far illa. Ambulanssjuksköterskor ska kunna identifiera och agera om misstanke finns att barn far illa samt informera vårdnadshavare om att orosanmälan ska göraBackground: threat, violence and assault offences against children under the age of 18 has become an occurring issue in the swedish society with increases of report of concerns. Healthcare workers are obliged to Socialtjänsten to write a report of concern if there’s a suspicion a child is abused. Paramedic nurses must be able to identify and act if there’s a suspicion that a child and/or children

In this work, a method to estimate the weld-zone temperature during induction welding of carbon fiber reinforced plastics (CFRP) is developed. Today several methods exist to measure, or in other ways ensure, the correct temperature in the weld. However, these methods all have some form of drawback ranging from leaving foreign material in the weld to complex sensor arrangements. The induction weldi
The European Spallation Source, ESS, is a project currently with 17 Partner Countries, and with Sweden and Denmark as host nations. The ESS main facility is being constructed in Lund, to ultimately become the world’s most powerful neutron source, providing around 30 times brighter neutron beams than any earlier facility. The Linear Accelerator, Linac, at the heart of ESS is fundamentally powered
The wood pulp industry has been around for a long time, but new higher quality pulp require more advanced solutions to old processes. One of these processes is the peroxide (PO) bleaching process, which is the last of a whole chain of bleaching processes at the Mörrum pulp processing plant. The aim of this thesis was to develop and study a model for the peroxide pulp bleaching process, and thereaf
