Den odränerade skjuvhållfastheten är en viktig geoteknisk parameter som man behöver ha en god uppfattning om i samband med byggnation på lerrika jordarter. Då flertalet av de vanligen tillämpade undersökningsmetoderna är väldigt tidskrävande och kostsamma, finns det ett stort intresse för att undersöka hur alternativa och samtidigt mer enkelt mätbara parametrar, så som flytindex (IL), förhåller siUndrained shear strength is a crucial parameter of the clay-rich sediments commonly used in the design process of geotechnical structures and is determined by several tests. As a considerable part of these tests are cost- and time consuming, it is of interest to investigate the potential relationship with shear strength (cu) with alternative, easily measurable parameters, such as liquidity index (

Syfte: Studien beskriver hur produkter med symboliskt värde fungerar inom access-based consumption (ABC), vilket uppnås genom att analysera hur bilen förknippas med identitet i denna kontext. Detta sker med utgångspunkt i individens motiv, tankar och drivkrafter. Metod: En kvalitativ studie har genomförts med ett hermeneutiskt fenomenologiskt tillvägagångssätt. Den bygger på en abduktiv ansats mePurpose: The study aims to describe and investigate how products with symbolic value operate within access-based consumption (ABC), which is realised through analysing how cars in car sharing relate to identity within this context.

This study is based on six interviews with a mixture of female and male police officers regarding their emotional labour. The purpose of the study has been to examine how the police handle their emotions, as well as account for experienced differences between feelings that arise at meetings with perpetrators or crime victims. The study also strives to gain a deeper understanding of what happens wh

Beowulfkvädet skrevs antagligen ned någon gång på 1000-talet och eftersom att vi bara har en kopia av manuskriptet kvar kan vi med säkerhet säga att historien om Beowulf inte ändrats de senaste 1000 åren. Trots detta har våra tolkningar av Beowulfkvädet varierat kraftigt de senaste 100 åren. Jag har med hjälp av ett 40-tal översättningar och analyser av Beowulfkvädet skrivna mellan åren 1901-2018 The Beowulf manuscript was probably written sometime during the eleventh century and since we only have one copy of the manuscript we can say for sure that the story of Beowulf has not changed during the last 1000 years. Regardless of this our interpretations of the Beowulf manuscript has changed dramatically the last 100 years. I have with the help of over 40 different translations and analyses o

The profane choir - finds and traces in the choir stalls of Lunds cathedral. When the choir in Lunds cathedral was being rebuilt in 1833 the choir-stalls were moved. Beneath them a surprising amount of well preserved artefacts were found. This included pencils, sandals, a large amount of coins, papers with writing and half a deck of playing cards. For almost 200 years these finds have received lit

This thesis investigates the effectiveness of applying recurrent neural networks (RNN) to detect communication errors between radio devices, also known as supervision violations, on imbalanced data. The task is to classify whether a supervision violation is to occur within seven days. The available data is in the form of radio packets, which are being re-sampled and pre-processed such that they ca

This project began with the current health problems of Chinese primary school students. The research shows a number of children have varying degrees of back problems which may cause serious health problems in the future. However, this problem has not caught enough attention of the public. It is also found that the main reasons for pupils' back problems were sedentary and frequent weight-beari

This thesis investigates the possibility of solving the problem of urban noise pollution by applying the principals of indoor acoustics on an outdoor environment. The city of Malmö, Sweden, was chosen due to its advanced world leading noise research and dynamic urban setting. All of the necessary information, data and measurements were acquired through research and practical experimentation in

Utsläpp av växthusgaser sedan mitten av 1800-talet har orsakat klimatförändring som bland annat leder till en ökning av både avsmältning i kryosfären och värmeutvidgning i haven, två faktorer som gjort att havsnivån stigit allt snabbare under det senaste århundradet. Havsnivåhöjning kan öka förekomsten av översvämningar av land, vägar och järnvägar samt påverka miljöobjekt, och på grund av detta iThis study uses GIS analyses to investigate the risk that increasing sea levels and highest projected highwater pose by increasing the risk of inundation on state-owned roads and railways as well as environmental objects in their side areas. This is done through an assessment of sea level rise projections and a risk analysis, which points out where vulnerable features are located and provides time

This master’s thesis deals with the distinct semantic weight carried by adverbials in German sentence constructions, where they can take on functions normally performed by verbs in other languages like English. While German mostly offers the same grammatical possibilities as English does to express certain types of semantic content verbally, the two languages differ when it comes to the preference

Examples of recurring themes in Berry’s literary work are the close relationship between farmer and the earth, the importance of belonging to a place/community, and having trust in the Creation. Examples of imagery in his poetry are song/singing, birds, trees

Vi har försökt hjälpa vidareutvecklingen av självkörande bilar med hjälp av att identifiera och klassificera parkeringsplatser i flygbilder. Problemet har visat sig vara svårt, och kanske inte kan lösas helt med hjälp av endast maskininlärningstekniker. Det finns dock tecken på att lösningen går mot rätt riktning, då vi kan se att systemet hittar de flesta av parkeringsplatserna som finns i exemplIn this thesis, the viability of using Convolutional Neural Networks to detect parking spaces using aerial imagery has been evaluated. Three state of the art networks have been tested - YOLOv3, RetinaNet, and Mask R-CNN. A dataset of urban parking lots and corresponding annotations was generated from scratch using a custom built GUI to annotate automatically generated images of parking lots from O

Införande av en klimatskatt på nötkött i Sveriges påverkan på förekomsten av kolorektalcancer Man har i flertalet studier påvisat att konsumtion av rött kött och processat kött (däribland nötkött) skulle kunna ha en negativ inverkan på människors hälsa. Framförallt visar studier på kopplingar mellan konsumtion av rött och processat och en ökad risk för kolorektalcancer. Vidare visar studier att pConsumption of red and processed meat has been found to effect human health and especially the occurrence of colorectal cancer. At the same time cattle farming and production of beef have been shown to severely effect the environment and particularly the climate. Taxation of beef could be an instrument to decrease the greenhouse gas emissions from the production of beef, but due to high transition
