Populärvetenskaplig sammanfattning Geografiska Informationssystem (GIS) är ett system för att hantera geografisk data som jämfört med traditionella forskningsmetoder gör det lättare att sammanställa och analysera dessa data. GIS började utvecklas i Nordamerika på 1960-talet och har under de senaste två decennierna haft stor påverkan på hur hanteringen av rumslig data går till. Användningsområdena Geographical Information System (GIS) is a technique that has revolutionized the way we process spatial data. The possibilities for GIS are endless and it is today used in a wide range of subject areas such as social planning, environmental monitoring and marketing. However, the process of implementing GIS is a long and usually runs in to a lot of problems. The aim of this study is to compare and

The type of pattern recognition methods used for controlling modern prosthetics, referred to here as single-label classification methods, restricts users to a small amount of movements. One prominent reason for this is that the accuracy of these classification methods decreases as the number of allowed movements is increased. In this work a possible solution to this problem is presented by looking

Ensamrätten till ett varumärke är en dynamisk rätt, där skyddsomfånget förändras över tid. Skyddsomfånget avgörs utefter graden av särskiljningsförmåga, vilket innebär ett varumärkes förmåga att särskilja varumärkesinnehavarens varor eller tjänster från andra näringsidkares varor eller tjänster. Vid varumärkesregistrering är särskiljningsförmåga ett absolut krav. Är fallet så att ett varumärke helA trademark right is a dynamic right, where the scope of protection alters over time. The scope of protection is determined according to the degree of distinctiveness, which means the trademark’s ability to distinguishing the goods and services of one trader from the goods and services of another. A trademark must be capable of distinguishing to be registered. If a trademark has completely lost it

To mitigate climate change and reach Sweden’s goal of becoming carbon neutral by 2045, or at an earlier stage of 2030 for 23 Swedish cities, urgent action is required to reduce greenhouse gas emissions. Due to the building sector’s significant contribution to carbon emissions, a crucial aspect in achieving these goals is improving the energy efficiency of existing buildings, as most of these will

Behovet av avancerad rening genom till exempel ozonering eller aktivt kol på avloppsrenings-verk blir tydligare i världen som följd av höga uppmätta nivåer av läkemedelsrester i recipienter. I länder som Schweiz är implementeringen redan idag lagstadgad och också i Sverige förväntas inom en överskådlig framtid krav införas på avlägsning av organiska mikroföreoreningar från avloppsvatten. I dagslägThe need for advanced wastewater treatment using for example ozonation or activated carbon is becoming exceedingly apparent because of high measured concentrations of pharmaceutical res-idues in recipients all over the world. In Switzerland for example there is legal requirements for the implementation of advanced treatment and within the foreseeable future also in Sweden the demands on the remova

According to a recent report by “Syria Relief” organisation, 75% of the Syrian Refugees who left Syria in the last six years are suffering from at least seven symptoms of Post-traumatic stress disorder (PTSD). Youth refugees are not finding the support they need; some of them are not even aware that they need it, which leads to a lack of communication and understanding in the evaluation of t

Knowledge brokerage and science communication are roles prone to forming “certainty troughs” (MacKenzie, 1990) between scientists and science’s downstream consumers. This has been studied as pertaining to in particular the geoscience area of CO2/climate, with an eye for the security domain’s use of science’s knowledge vertical. As background, the areas of knowledge acquisition, undue politicizatio

Den svenska bostadsmarknaden präglas av en bostadsbristsituation, en situation som enligt Boverket förvärrats av omvärldshändelser som covid-19 och kriget i Ukraina. Det är i denna kontext intressant att undersöka orsaken och implikationerna av observerade skillnader i belåningsgrad och marknadsvärdestillväxt mellan kommunala bostadsbolag och privata fastighetsbolag. Syftet med arbetet är att unIn Sweden it has for many years been the common understanding that there is a shortage of housing on the housing market, a situation that according to Boverket has been further worsened by recent world events such as the Covid-19 pandemic and the Russian war of aggression against Ukraine. In this context it was interesting to study the cause of and implications of observed differences in the grow

Inom forskningsfältet har autenticitet visat sig vara en viktig aspekt för välbefinnande, men det har genomförts få kvalitativa studier på fenomenet. Denna studies syfte var att ge en nyanserad beskrivning av och fördjupa förståelsen för svenska, manliga gymnasieungdomars upplevelse av autenticitet. Frågeställningarna undersöker hur autenticitet som tillstånd upplevs, upplevelsen av relationen melAuthenticity has been proven to be a significant component of well-being, but few studies with qualitative methodology have been conducted on the matter. The purpose of this study is to give a nuanced portrayal and an in-depth understanding of how state authenticity is experienced by Swedish, male high school students. We examine how state authenticity is experienced, the experience of the relatio

Physics-informed neural networks integrate physical laws into machine learning models to solve differential equations. This thesis investigates an inverse physics-informed neural network framework for estimating viscosity in Tetra Pak’s injection molding process, where direct measurements are not possible. By enforcing the Navier-Stokes equations and using sparse velocity and pressure data, a virt

Att ha en webb som är tillgänglig åt alla människor är viktigt i dagens digitala samhälle. För att designa tillgängliga webbplatser finns flera lagar, riktlinjer och rekommendationer som offentliga aktörer bör försöka efterleva. Men vad innebär dessa krav i praktiken? Detta examensarbete, genomfört i samarbete med Region Skåne, syftar till att undersöka om automatiserade testverktyg kan användas fIn today’s digital society, accessible websites are more important than ever. To design websites that are accessible to everyone there are many laws, guidelines and recommendations that public organizations and authorities need to comply with. But how do you comply with these in Sweden, and how do you test your websites for issues with accessibility? This thesis, in cooperation with Region Skåne a

Denna fallstudie syftar till att utvinna fördjupad kunskap om mellanchefens komplexa och mångtydiga roll som meningsskapare och meningsgivare under en digitaliseringsförändring. Tidigare forskning har nämligen betonat mellanchefens roll som avgörande under en förändringsprocess. Detta eftersom mellancheferna innehar en roll som meningsskapare när de omvandlar övergripande organisationsinformation The purpose of this case study is to gain a deepened knowledge about the middle manager's complex and ambiguous role as sensemakers and sensegivers during a digital change. Former research has emphasized the middle manager’s role as crucial during a process of change. This because the middle managers hold a role as sensemakers when they convert the organizational information to their own units

Powders are complex systems that depend strongly on how the individual particles in- teract and their surroundings. Understanding powders behaviour under certain conditions is very important for the product in many applications, one of them being Additive Manu- facturing (AM). The overall goal of this study is to understand and quantify the effect of flow additives in combination with iron powder.

Events that can be described as high impact and low probability (HILP-events) have been proven difficult to deal with, for example background data often is sparse. Due to the construction of traffic tunnels these events need to be taken into consideration. A tool for doing this is risk analysis, and with this tool the events can be identified and handled with a quantitative or qualitative approach

Denna uppsats, som inriktar sig på prövning av dopingrelaterade ärenden, behandlar intressekonflikten som uppstår mellan idrottsutövarens rätt till en rättvis dopingprocess och idrottens autonomi. Idrottens värld har länge valt att ha en långtgående självbestämmanderätt och de anser att autonomin är en fundamental utgångspunkt för att idrottens verksamhet ska kunna fortsätta på ett fungerande sättThis thesis deals with the conflict of interest arising between an athlete’s right to a fair trial, relating to doping, and the autonomy of sports. The world of sport has claimed a far-going autonomy for a long time. They believe that autonomy is a fundamental ground for the continuance of a well functioning world of sport. Today, the organs of the national sport organisation, Riksidrottsförbundet

En viktig förmåga hos naturvetarstudenter är att kunna kommunicera sitt ämne på ett förståeligt sätt till lekmän. Forskning visar dock att inte alla naturvetarstudenter uppfyller detta krav – ett problem som delvis kan härledas till det svårförståeliga naturvetenskapliga språket. Ett sätt att göra naturvetenskapen begriplig för lekmän, och för studenterna själva, kan vara populärvetenskaplig kommuIt is important that natural science students are able to communicate their expert knowledge to laymen. Research shows however that not all students fulfill this demand, which might be due to the complexity of scientific language. One way of making natural science easier to understand, both to laymen and the students themselves, is to use popular scientific communication. The purpose of this study
