Saint-Gobain Ecophon manufactures acoustic ceiling tiles made primarily of glass wool and are interested in exploring the idea of a new manufacturing technique – using thinner layers of material and laminating these together. The possible benefits are, amongst others, the ability to use different kinds of material where they are the most useful, reduced costs, larger amounts of recycled material,
Market indices based on market capitalization have been argued to be the most mean-variance efficient for a long time. In recent years, this argument has been questioned and other methods of weighting portfolios have been suggested. One of these is the weighting by fundamental indexation. This thesis investigates whether fundamentally-weighted portfolios outperform portfolios weighted by market ca
This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. Modelling software is developed to apply the proposed adaption. Case studies ar
Arbetet syftar till att utreda på vilket sätt arkitekturen runt omkring oss påverkar vårt välmående. I arbetet undersöks detta med syftet att se hur arkitekturen kan användas inom psykiatrin för att påskynda och förbättra vården. Den första delen av arbetet är en teoretisk del, där de grundläggande förutsättningarna i samhället läggs fram. Psykiatrins arkitektur tas upp ur ett historiskt perspektThe project looks into the question how architecture and the environment around us affects out wellbeing. In the project I examine this with the purpose to understand how knowledge about this may be used to improve health care. The main part of the project looks into the theoretical part of the question, looking at the fundamental prerequisites in our society. The psychiatric healthcare is examin
När avfall kommer på tal, inte bara inom avfallsbranschen, finns idag ett stort fokus på att minska de totala avfallsmängderna och att öka utsorteringen av återvinningsbart material. Trots det ökar de nationella avfallsmängderna. För att göra arbetet med både avfallsminimering och en ökad utsorteringsgrad så verkningsfullt som möjligt, är det viktigt att veta vad som påverkar avfallsmängderna. SyfWhen waste is on the agenda, not only in the waste industry but in general, there is a high focus on reducing the amount of waste and to increase the amount of sorted recyclable material. Despite this, the total waste amount in Sweden is increasing. To be able to minimize the amount of waste and maximize the waste sorting degree it is important to know the factors that affect the waste stream. The
Studien undersöker om det råder en överreaktion på Stockholmsbörsen på lång sikt och om det därmed är lämpligt att använda sig av en contrarian investeringsstrategi. Denna studie använder De Bondt och Thalers (1985) ”The contrarian investment strategy” på aktier listade på OMXS Large-, Mid- och Smallcap under en period på 18 år från 2001-01-01 till 2018-12-01. Resultatet som redovisades i studien
Classification of surfaces in the near field using millimeter-wave radar commonly considers the use of polarization based methods for road condition monitoring. When a surface consists of larger structures one instead wishes to monitor the surface topography. Analysis of scattering from rough surfaces is highly complex and relies on prior knowledge of surface structure. In this work a device movin
Från ett presspulver och ett nytt bindemedelssystem har en ny sammansättning för metallformsprutning utvecklats. Kraven som ställts på nya sammansättningen var att de ingående komponenterna ska vara homogent fördelade och att sammansättningen ska ha de rätta reologiska egenskaperna. Presspulvret bestod huvudsakligen av volframkarbid, kobolt och polyetylenglykol. Presspulvret blandades med ytterlig
This thesis is developed in collaboration with Tetra Pak AB. The assignment was to create a mobile application which would present information from a platform called ACT, Automation & Connectivity Tools. The mobile application would be called ACT Mobile and would also have functionality from ACT and one application which ACT provides. The ACT platform is a collection of applications that helps
This report is about using generative adversarial networks with predictive coding networks for future frame prediction. Model selection choices for the components of the network are explored by training different models and testing their performance on next frame prediction in digital video from driving scenarios. Benefits and issues of using adversarial loss for future frame prediction as well as
Vatten, både i flytande- och fast form, anses vara en av de stora riskerna till uppkomst av skador på vägar. Det kan nå vägkonstruktionen redan under byggskedet eller i ett senare skede, vilket ställer stora krav på att hålla det borta från vägkroppen för att eliminera risken för uppkomst av följdproblem. En väg genomgår tre viktiga faser, Projektering, Produktion samt Drift- och underhåll. Bristf
Det Västra segmentet och Mediansegmentet i Idefjordenterrängen omarbetades under metamorfos och migmatitbildning under den Svekonorvegiska orogenesen (ca. 1 Ga), men det råder fortfarande oklarheter kring tidpunkterna för dessa händelser inom och mellan de två segmenten. Denna studie visar att Svekonorvegisk metamorfos och associerad migmatitbildning inte är samtida i Västra segmentet och MedianseThe Western and Median Segments of the Idefjorden terrane have been metamorphosed and migmatized during the Sveconorwegian orogeny (ca. 1 Ga), but the timing of these events between the two segments remains unclear. Here I show that Sveconorwegian metamorphism and associated migmatite formation is not coeval between the Western and Median Segments and that there is a contrast between the segments
An investigation into how the authors moods influences her piano playing. The methods has been used on this thesis were diary keeping, authors concert experiences and recordings as well as an interview, all in combination with literature on moods and concentration. As an result could say that the the author believes that her moods influences her piano playing if she is not capable of to switch he
Sweden has a proportional electoral system where the seats in parliament are distributed according to the modified St. Laguë method. In 2015, the Swedish parliament approved amendments to the electoral law in order to improve proportionality in the national elections. The amendments came about after a failure to produce a proportional distribution of parliamentary seats after the 2010 national ele
The thesis attempts to explore possibilities of implementing a user interface visualization to a machine learning algorithm. As the algorithm in the thesis does not take soft values into account, the visualization is meant to highlight its’ drawbacks and aware the end user of how the results were generated. Therefore the graphical representation is aimed to fortify the algorithm as decision making
Den här kvalitetsutvecklingsstudien på en utbildningsmottagning för blivande psykologer syftade till att undersöka om det fanns någon skillnad mellan de som tidigt hoppade av erbjuden psykoterapi och de som fortsatte behandlingen. Studien hade en kvasiexperimentell design utan randomisering eller kontrollgrupp. Deltagarna bestod av 519 klinter som sökt hjälp på Psykoterapimottagningen vid Lunds un
Det finns många typer av säkerhetsstudier. En av dessa är en så kallad konfliktstudie. När man idag gör en traditionell konfliktstudie analyserar man trafiksäkerheten, oftast utifrån video-data. Det vill säga en observering av den verkliga situationen. En traditionell konfliktstudie har gjorts av Svensson & Ekblad, (2018) på en korsning vid Heleneholmsstigen/Ystadvägen i Malmö där man byggt omThere are many types of traffic studies. One of these is a so-called conflict study. Today when you do a traditional conflict study, you usually analyze traffic safety based on video data, which is an observation of the real situation. A traditional conflict study was made by Svensson & Ekblad, (2018) at a crossing at Heleneholmsstigen/Ystadvägen in Malmö, where a bicycle crossing was rebuilt.
The purpose of this master’s thesis is to provide a contribution to the research body regarding consumer returns, particularly within the online fashion retail industry. A quantitative data analysis approach is chosen and two main methods are used: data study that aims to identify patterns and interesting relationships in the data, and a simulation study that uses real input data to attempt to ide
In this thesis, an automatic emergency braking is developed using camera data. The vehicle used in the development is a Volvo XC90 equipped with a prototype version of a camera-based, automated parking system. The camera detection output is a 2D version of the static environment populated with obstacles represented by convex hulls. These are used to safely avoid real-world obstacles by braking if
A cascade matched filtering (CMF) approach is purposed for filtering rectangular pulse train tracking signals, with known signal characteristics, in an embedded signal detection unit. Two adaptive detection algorithms are suggested, adapting to alterations in noise signal characteristics, due to environmental changes. The end product was an embedded tracking detection system, enabled to identify d
