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

In the 'on-the-go' society of today, the use of single unit beverage packages has increased. Consequently, the interaction between the consumer and the package have also attracted greater interest when trying to gain advantages in a competitive market. One way of gaining such an advantage is by decreasing the developing costs of products: either by reducing time spent, or money invested in
In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta
In recent years, Deep Learning has proven to be an outstanding tool in the field of computer vision showing promising results in different fields such as the analysis of medical images, obstacle detection for self-driving cars, automatic image caption generation, etc. In the case of Archaeology, the adoption of these methods in the detection of archaeological structures from aerial images has been
This thesis has investigated the potential benefits of using transfer learning when training convolu- tional neural networks for the task of autonomously driving a car. Three transfer learning networks were trained and compared with a conventionally trained convolutional neural network. The first conclusion is that training, as expected, is considerably quicker when using transfer learning. More s
As design students who are about to graduate, we asked ourselves what it means to enter the professional life as a designer. We wanted to investigate how a young designer is able to make a living within the design profession. Additionally, we explored how we can include Northern European industrial manufacturing into our research and design process to learn more about mass production and its poten
I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. Detta fenomen kan leda till alIn this study, the phenomenon of black corrosion is characterized by both literature studies on corrosion processes and corrosion products, and by analyzing field samples from saline subaqueous concrete structures in southern Sweden. Anaerobic corrosion of reinforcement in water-saturated concrete is an extensive but yet relatively unnoticed problem. This phenomenon can lead to serious damages tha
The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. Lately these RDF stores have been tested for processing and maintenance o
A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p
