Thanks to the ever-increasing computational power, machine learning has become a staple in computer science. Many computer vision methods have become so reliable that their implementation in the surveillance industry is now the de facto standard for many object detection and classification tasks. The use of machine learning for surveillance is not confined to images and videos, however, it is also
Aims and methods: This study examines the discourse surrounding honour-related violence and oppression, referred to as honour violence. A discourse analysis was conducted on material from the state and organisations working with HRVF, collaborating with midwives. Two in-depth interviews with midwives gathered firsthand experiences from professionals encountering potential victims of honour violenc
Den påtagliga betydelsen av klimatfrågor framträder i allt högre grad. Byggsektorn har en betydande inverkan på klimatet genom sin resursanvändning och avfallsgenerering, vilket tydligt framgår då sektorn står för en tredjedel av Sveriges totala avfallsgenerering. Trä har för närvarande en låg resurseffektivitet och värdet hos materialet utnyttjas inte till sitt fullo. Den omfattande förbrukningenThe tangible significance of climate issues is increasingly evident. The construction sector significantly impacts the climate through resource utilization and waste generation, as is evidenced by the sector's contribution to one-third of Sweden's total waste generation. The current situation shows that wood exhibits low resource efficiency, with its value not fully exploited. The extensiv
This thesis investigates the effectiveness of step size control in the numerical simulation of Stochastic Differential Equations (SDEs). The study is divided into a theoretical exploration and a series of numerical experiments. The theoretical section introduces key definitions and theorems, delves into the properties of Brownian motion, and examines the conditions under which solutions to SDEs ca
Detta examensarbete behandlar effekten av slagg som ersättningsmaterial till Portlandcement och dess påverkan på hållfasthetsutvecklingen, med krav på den tidiga hållfastheten. Syftet med denna studie är att undersöka möjligheten att förbättra betong med hänsyn till dess klimatpåverkan genom att ersätta en del av Portlandcement med ett mindre miljöbelastande bindemedel. I den experimentella delenThis thesis addresses the effect of slag as a replacement material for Portland cement and its impact on strength development, with focus on early strength requirements. The aim of this study is to explore the possibility of improving concrete in terms of its environmental impact by using more eco-friendly material. In the experimental part of this work, various mixtures with different slag amount
This research paper investigates the technical feasibility, system requirements, performance characteristics, and potential for optimization of an industrial heat pump in a district heating system, using the Modelon Impact platform. The study aims to provide a comprehensive understanding of the benefits and limitations of using cloud-based simulation platforms for the design and analysis of indust
Syftet med vårt arbete är att identifiera vilka metoder och verktyg som finns kopplade till mental träning samt hur lärare kan använda sig av dessa i musikundervisning. Vår första forskningsfråga handlar om hur mental träning används idag, vilket behov som finns och vilka metoder som används. Vi är intresserade av att ta reda på hur aktiva musiker använder sig av mentala redskap samt ta del av der
The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. It differs from a conventional heat pipe device in design and opera
With an ongoing energy crisis in Europe and an ever-evolving political climate where the environmental impacts of industries are regarded as a top priority, the topic of energy efficiency is high on everyone’s agenda. Mathematical optimization of energy consumption requires a model of the problem at hand. In this thesis linear regression is compared with the gradient boosted trees method and a neu
Cities face multiple social-ecological challenges, which nature-based solutions (NBS) promise to address. Strategies to mainstream NBS have only achieved partial success, hence recent studies suggest that inner dimensions - mindsets and transformative capacities - must be mainstreamed simultaneously. This study investigates municipal employees' engagement with inner dimensions, its impact on s
The future of agriculture depends on healthy soils, but soils are degrading within dominant agricultural systems, also in Denmark. Pioneer farmers seek a sustainable transition towards soil-centered management. However, reinforcing feedback loops in current agriculture is blocking such a transition. Founded in emancipatory social science and critical utopian action research, this thesis, in collab
Att under sin uppväxt bli utsatt för mobbning av jämnåriga kan innebära långtgående negativa konsekvenser för hälsa och mående för den utsatta. Fortfarande är det många barns vardag att vara utsatta för mobbning. Mobbningen sker idag inte enbart i skolmiljö utan även på nätet. Syftet med studien var att undersöka föräldrars syn på deras möjlighet att agera vid sitt eget barns utsatthet för skol- eDuring childhood and adolescence, being subjected to bullying by peers can have far-reaching negative consequences for the health and well-being of the victim. Unfortunately, many children continue to experience bullying, which now occurs not only in school environments but also online. The purpose of this study was to explore parents' perspectives on their ability to respond when their own ch
Regularly described as hotspots for marine life, seamounts are important foraging grounds for marine predators. In surface waters over seamounts, diel vertically migrating organisms can be aggregated, making seamounts potentially attractive and profitable food sources for predators such as seabirds. Still, the potential association between seabirds and seamounts has seldom been described and littl
Bakgrund: Samtliga Svenska vattenkraftverk och dammar ska under en tjugoårsperiod få moderna miljövillkor inom den nationella planen för omprövning av vattenkraft (NAP). Nio svenska kraftbolag finansierar tillsammans, genom Vattenkraftens Miljöfond Sverige AB (Fonden), kostnader som uppstår i samband med miljöåtgärder inom NAP. Tidigare studier visar att det finns en anlockningsproblematik vid de
This paper analyzes the set of political skills that middle managers use to navigate the aerospace industry. The current study considers Mintzberg’s (1985), Ferris et al.’s (2007), and Treadway et al.’s (2005) conceptualization of organizations as political arenas, will, and skills. Thus, it constitutes a theoretical base to create a new tailored political skills framework that could help aerospac
Som en del i utvecklingen mot grönare och miljövänligare processer, samt ett behov av ytterst specifika reaktioner, vill AAK AB utvidga sin användning av lipaser i sin produktion av strukturerade triacylglyceroler (STAGs). AAK vill bygga upp ett bibliotek av utvärderade lipaser. Syftet med detta examensarbete är att bidra till detta bibliotek genom att karakterisera en grupp kommersiellt tillgänglAs part of a switch towards more green and environmentally friendly processes, together with a need for highly specific reactions, AAK AB wants to broaden their use of lipases in the production of structured triacylglycerols (STAGs). AAK are working on creating a lipase library where several lipases are evaluated, this master thesis aims to contribute to this lipase library by characterizing a sel
