Surface Classification with Millimeter-Wave Radar for Constant Velocity Devices using Temporal Features and Machine Learning

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

Nytt bindemedelsystem för metallformsprutning

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.

Vatten i vägkonstruktioner

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. BristfWater, both as a liquid and solid, is considered to be one of the major hazards that can give rise to damages on the road. It can affect the road during the construction stage but also at a later stage, which places a great demand on keeping water away from roads in order to eliminate the risks of secondary problems. A road goes through three important stages, Design, Production, Running operation

Zircon U-Pb constraints on the timing of Sveconorwegian migmatite formation in the Western and Median Segments of the Idefjorden terrane, SW Sweden

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

Proportionalitet i svenska Riksdagsval: En analys av den reformerade vallagen med Dirichlet-fördelade simuleringar

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

Web interface for machine learning as decision making support

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

Tidiga avhopp vid erbjuden psykoterapi hos studentterapeuter - en kvalitetsutvecklingsstudie

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

Simulering - Ett alternativ till den traditionella konfliktstudien?

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.
