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

Metod: Studien tillämpar en kvantitativ metod och använder statistiska undersökningar för att bestämma och förklara beslutet om betalningsmetod vid företagsförvärv. Teoretiskt perspektiv: Studien baseras på teoretiska ramverk som inkludPurpose: The purpose of this study is to determine what factors have a statistically significant impact on the payment method decision for Swedish corporate acquisitions. Methodology: The study adopts a quantitative method with a statistical approach to determine and explain the payment method decision in corporate acquisitions. Theoretical perspectives: This study is based on a theoretical framew

The writer, farmer, Christian pacifist, and “eco-poet” Wendell Berry has written and published novels, essays, and poetry since early 1960s. 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

2013 beslutades att Fritidsbadet i Ystad var i för dåligt skick för att fortsätta vara badhus och kommunen valde därför att permanent stänga badet. Samma år utlystes en markanvisningstävling för byggnaden med målsättning att hitta en ny användning för Fritidsbadet som funnits sedan 1961. Förslaget som vann och började realiseras 2017 ville göra badet till ett hotell och konferenscenter, vilket ja2013 it was concluded that Fritidsbadet in Ystad was in too bad condition to continue to be a public bath and the municipality decided to permanently close it. The same year an architecture completion was announced and the goal was to find a new use for Fritidsbadet that was built 1961. The winning proposal, that started to become realized in 2017, wants the bath to become a hotel, which I as a lo

Du vaknar på morgonen kollar på din mobiltelefon om det hänt något nytt och spännande, tar datorn med dig till jobbet eller plugget och efter en lång dag sätter du dig i soffan och slår på Tvn. Alla dessa prylar har en central roll i vår vardag och är baserade på en gemensam nämnare som möjliggjort detta– transistorn. I din mobiltelefon finns det ungefär 200 miljarder av dem, i datorn ännu fler. TWith the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. In the pursuit of further improving the transistor structure and its performance new approaches are being evaluated. A very

Högt över och långt under den galaktiska disken av Vintergatan svävar gigantiska stjärnhopar som tros ha existerat sedan begynnelsen av galaxen. Astronomer är fram tills idag förbryllade över hur de hamnade där och hur de kommer att utvecklas över tid i sin bana kring galaxen. Något som forskare är säkra på är att den stjärntäta tunga disken hos Vintergatan drar i stjärnorna i de fjärran hoparna mThe evolution of globular star clusters tells the history of the formation of galaxies, how stellar streams might have formed and how the future of the Universe might look like. Although the general theoretical background of the evolution is well understood, it is difficult to conduct accurate and realistic computer simulations of objects containing thousands of interacting bodies. This project in

This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. These ions have a partially filled 4f shell, protected by the full 5s and 5p shell from the environment wh
