In this thesis we research beamforming capabilities of the UEs equipped with several antennas in a 5G scenario. We define a system model based on the use of phase codebooks that allow to change the radiation patterns of the arrays of antennas installed in the UE. Within this system model, we obtain optimized codebooks in terms of two metrics, which we consider to be of interest in this scenario, e
Utveckling av effektiv drift och underhåll av fastigheter är ett kontinuerligt arbete som pågår under hela fastighetens livcykel. För att en byggnad ska vara energieffektiv så är faktorer som byggnadsskal, primärenergi och lokala förutsättningar av stor betydelse. Byggnadsautomation möjliggör ytterligare besparingar genom att effektivt begränsa energiflöden utan att påverka upplevd komfort hos bru
Augmented reality is a field which is getting increased funding every year, as more businesses are realizing the potential of rendering virtual objects in the real world. As the equipment gets more commercialized, the costs will get lowered while performance also goes up. As of now, augmented reality mostly makes use of plane detection and marker detection to find and locate objects. We want to in

Background/introduction: Scania supply chain is responsible for packaging to protect parts during transportation from their suppliers around the world. For many years Scania has used returnable packaging for inbound logistics of automotive parts. Scania packaging can be divided into two groups; namely Standard packaging and Special packaging. Problem description: When introducing a newer solution
Topology optimization with respect to eigenfrequencies is one example of an objective that has been studied extensively for small deformations. Few have however investigated this type of optimization for structures undergoing finite deformations. In this work, we thus expand the topology optimization formulations for eigenfrequency optimization to a nonlinear hyperelastic material model. When wo
In crisis, media plays an important role in connecting people, communicating information and assisting with potential new dimensions, designs and approach. Media representation holds key for ongoing rescue program and upcoming rebuilding program, especially in developing countries where no one knows when the real impact of disaster will come to an end. Moreover, people interest or participation in
The reaction–diffusion equation (RDE) is a natural way of describing a system where there is not only diffusion but also interaction with its surroundings. The RDE has been the topic of interest in previous papers for its usefulness of explaining pattern formations in nature. The static RDE has, in one dimension, the form of a Newton equation. We study a discretized version of this equation, with
Vi har arbetat med trådlös kommunikation för att undersöka en möjlig lösning för att streama video från ett fordon i rörelse till en stationär mottagare. Under våra tester så använde vi video-kodnings standarderna H.264 och MJPEG. Vi testade även att använda både WiFi samt LTE som trådlösa medium för att transportera data mellan enheter. Vi utförde sedermera tester på kombinationer av dessa mediumFor our master's thesis we have worked with a company called Uniti to help them establish a system for communicating with their autonomous vehicle during a public demonstration. This included handling a video feed from the vehicle as well as assuring low latency for said feed. For the purposes of this thesis the targeted latency was below 200ms. In order to construct a solution which met our
We analyze how automatically generated crash reports can be used to aid in the process of software defect categorization. The crash reports are automatically generated logs, which vary widely in both format and in information content. Each crash report used is linked to its corresponding, human-written bug report. The problem is handled as a long text-based classification problem. Several differe
A convolutional neural network (CNN) training framework is described and implemented. The framework is used to train and evaluate an audio classification system, focused on evaluating differences in audio representation. The dataset used is ESC-50, containing 50 different classes of audio. We used SBCNN, a promising architecture suited for embedded systems because of its relatively small size. Sev
With high associated costs, both in terms of time and economics, false alarms are a ubiquitous problem in camera surveillance. There exists many methods of lowering the rate of false alarms from motion detection, most of which are based around using static rules and filters such as area of interest, cross-line detection and filtering of swaying objects. This thesis explores the possibilities of us
Syftet med examensarbetet är att undersöka hur fastighetsbildningen för jordbruksändamål kan anpassas till det moderna jordbruket. Nedan följer bakgrunden till mina förslag på anpassning av fastighetsbildningen till det moderna jordbruket: Jordbrukarna föredrar stora jordbruksfastigheter. Idag är det bara riktigt stora jordbruksfastigheter som anses skyddsvärda enligt 3 kap. 6 § FBL. Det är viktThe purpose of this master thesis is to examine how property formation for agricultural purposes can be accommodated to the modern-day agriculture. Agricultural holdings in the size ranges 15-30 and 30-100 hectares are declining rapidly in Sweden. It was common that agriculturalists in Helsingborg municipality that had an agricultural holding in the size range of 30-100 hectares had a hard time t
Digital teknik inom beroendevården och användarnas upplevelser av dessa är ett relativt outforskat område och då stigmatisering av substansberoende, i detta fallet alkoholism, utgör ett hinder för individer att både söka hjälp och upprätthålla en nykterhet. Denna studie syftar till att undersöka vilken roll det digitala vårdverktyget TripleA fyller i åtta användares liv i relation till deras missbDigital technology in the addiction care sector and the user’s experiences of this is a relatively unexplored area, and stigmatization of substance dependence, in this case alcoholism, constitutes an obstacle for individuals to seek help and to maintain sobriety. This study aims to investigating the role of the digital care tool TripleA in the lives of eight users in relation to their addiction, a
This thesis explores the multiple representations of Syrian men in the non-heterosexual Lebanese context. Through qualitative research methods, eleven Lebanese men who have sex with men are interviewed about their sexual sociality with Syrian men. In terms of eroticization, this thesis exposes that Western and negotiated forms of orientalism overlap and produce multiple and even contradictory form
In this thesis, I explore the bordering experiences of Syrians who frequently cross the border into Lebanon during the Syrian conflict. I draw on five in-depth interviews conducted in March 2018 to show how they live, understand and manipulate the border. Through a theoretically informed analysis, using the concepts of the social construction of reality (Berger and Luckmann), habitus (Bourdieu) an
A technique for measuring oxygen concentration in the lungs of preterm infants is one of the latest advancements in neonatal care. It is called GAs in Scattering Media Absorption Spectroscopy (GASMAS) and enables non-invasive, bed-side monitoring of the lung function of our most fragile patients, preterm newborns. The technique is promising and its potential is now evaluated in preparation for cli
Vid dimensionering av brandskyddet för en byggnad är utrymning en viktig aspekt. För att få en bild av hur utrymning sker i byggnader finns det en del simuleringsprogram till förfogande. Simuleringarna bygger på indata som användaren stoppar in i programmet och beroende på vilka värden som används kan resultatet variera. Thompson et al. (2015) förklarar att de värden på flöden som används idag saThe aim of this thesis is to investigate person density in relation to flow and speed in stairs and also how the different configurations affect the inter-person distance. This is done by observing people's movement in real environments. These observations were made at a staircase at Lindab Arena in Ängelholm on several occasions in the event that visitors were about to leave the arena after a
