Mexico will need to provide about 26 million housing units by 2030 and it is only through the understanding of the current situation and the awareness of the main challenges that affect the housing problems, that appropriate responses to the context can be proposed. By providing decent, secure and affordable housing, social problems can be reduced improving health and security, local economies can

Databehandling av signaler från millimetervågsradar i realtid Radarsensorer som använder millimetervågor är väldigt användbara inom avkänningsteknik, som har tillämpningar inom bland annat sjukvården, autonoma robotar, osv. Detta examensarbete bygger vidare på en genomförbarhetsstudie som med positiva resultat undersökte om det var möjligt att med hjälp av elektronik och algoritmer förhindra fallBased on the feasibility study [4], the goal of this master thesis is to compile custom firmware for the XM112 Pulsed Coherent Radar Module, which features a state of the art radar sensor integrated with a microcontroller unit (MCU). This allows the use of custom firmware to check the plausibility of real-time data processing on the radar signals and will lay some of the groundwork for further dev

The next big step to improve prosthetics and make the lives of people living with certain physical disabilities less restricted is to provide them with sensory feedback. Today most feedback systems used in prosthetics are mechanical but with the recent developments in sensors and the processing of their input electrical stimulation is becoming an increasingly promising way to convey touch, pressur

Överkonsumtion och utnyttjandet av jordens resurser är en fundamental del till en ökning av avfall i Sverige. År 2016 integrerades EU:s avfallstrappa i miljöbalken, som innefattar enligt svensk och europeisk avfallslagstiftning, ligger den första prioriteringen på att förebygga uppkomsten av avfall, då den just representerar det första steget på avfallstrappan. Vikten av att införa avfallsförebyggThe purpose of this study is to take part in municipal inspectors' experience and perceptions regarding the implementation of waste prevention measures in their daily work. A qualitative interview study, in order to identify areas of improvements and failures in the work of improving waste prevention in the municipality's operations.The hope was to see any differences and similarities for

Denna studie fokuserar på en sedimentsekvens som hämtats från Odensjön, i Söderåsens nationalpark i Skåne, södra Sverige. Den undersökta sekvensen, som täcker de översta 86 cm av sedimenten, är unik på grund av dess väldigt tydliga årsvarv, som har möjliggjort en precis datering (Hertzman in prep.). Tilläggsvis, den stora mängden välbevarade Fagus sylvatica-blad synliga i sedimenten yngre än cirkaThis study focuses on a sediment sequence retrieved from Lake Odensjön, positioned within Söderåsen National Park in Scania, southern Sweden. The investigated sequence, covering the uppermost 86 cm of sediments, is unique due to its very distinct annual varves, which have allowed for precise dating (Hertzman in prep.). In addition, the large amount of well-preserved Fagus sylvatica leaves visible

This paper examines to what extent a government decision concerning a debated climate issue was a result of the efforts of a climate justice campaign. In 2017, a campaign organisation was launched under the name ‘Fossilgasfällan’, and two and a half years later the Swedish government essentially met their most important demand. I argue that this was very likely indeed a consequence of a sustained

Kroppsliga symtom som hänger samman med psykologiska faktorer är vanligt förekommande och utgör en stor utmaning för hälso- och sjukvård. Tidigare forskning har visat enkla samband mellan svåra upplevelser under barndomen, alexitymi, svårigheter med emotionsreglering och kroppsliga symtom. Syftet med den aktuella studien var att studera dessa variabler tillsammans och undersöka huruvida alexitymi Somatic symptoms are commonly associated with psychological factors, and their management presents considerable challenge to healthcare systems. Past research has shown simple associations between adverse childhood experiences (ACEs), alexithymia, emotion regulation difficulties, and somatic symptoms. The purpose of this study was to investigate the aforementioned variables simultaneously, while a

Den aktuella studiens syfte var att undersöka om det finns ett samband mellan upptagenhet av kost och träning och fyra psykologiska faktorer: hälsoångest, självkänsla, känsla av sammanhang och kroppsuppfattning, då psykiskt välmående som begrepp är alltför mångfacetterat. Ett ytterligare syfte var att undersöka om upptagenhet av kost och träning skiljde sig åt beroende på specifika egenskaper hos The purpose of the present study was to examine whether there are connections between preoccupation with diet, and exercise, and four psychological factors: health anxiety, self-esteem, sense of coherence, and body image, since psychological well- being is a broadly used term. Another aim was to examine whether the preoccupation with diet, and exercise differed depending on some specific character

This thesis investigates Automatic Text Summarization and how it can be used to generate summaries of patent documents. The purpose of the generated summary was to convey the patent document’s subject so that the reader could decide whether the patent document is relevant and should be read in full or could be discarded. This, in order to reduce the time patent attorneys need to spend reading full

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 mThrough a social semiotic multimodal analysis together with a queer theoretical approach, this essay aims to provide new insights into the field of strategic communication, marketing and non-stereotypical advertising. Advertising has for a long time used stereotypical representations of people which can be problematic since it is based on generalizing assumptions of individuals and groups. Since a

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

Leverantörsutvärdering är något som väldigt många företag måste genomföra och som ofta är ett komplext problem med många parametrar och variabler inblandade. Detta arbete har tagit fram ett framework för hur attribut och prestandamått bör vara konstruerade för att ge en så representativ poängsättning som möjligt, samt en modell för övervakning och kontroll av leverantörens produkter baserat på speEvaluating 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
