A lot of research involves spectral or polarimetric imaging in applications such as medicine, material science, and molecular science. Spectral imaging allows the acquisition of multiple spectral bands of a scene, while polarimetric imaging enables the extraction of a scene's polarisation. Combining the two imaging techniques simultaneously is referred to as multiparametric imaging. Today, onl
The demand for better networks and faster speeds within telecommunications has been an ever-growing ambition for the last decade. A promising candidate for dealing with this demand is distributed multiple-input multiple-output (D- MIMO) systems that combine large-scale antenna arrays and decentralized node architectures. However, evaluating the possibilities and limitations of such system requires
Selecting the right stainless-steel (SS) grade for food processing equipment is a critical decision, since processing environments vary widely and a grade that performs well under one set of conditions may be inadequate under another. The following study evaluates the pitting corrosion resistance of three grades commonly used in the food industry, 316L, 2205 DSS and 254 SMO, under varying chloride

The component is intended to interact with the authorization service from Okta with the correct type of authorization flow to allow or disallow access to the web application’s resources. At first, knowledge was gathered regarding the web appli
This thesis investigates the modern phenomena of ruralisation; people leave the city for a life in a calm rural region, explained by theories of lifestyle migration, push pull effects and new expectations. During the last 20 years, migration from Stockholm to four Swedish rural regions have increased with 37 percent according to collected statistics, answering the first research question on how mi
Skyddsombudens rätt att stoppa arbetet ska användas restriktivt. Samtidigt har Corona påverkat hela världen och viruset kan innebära dödlig utgång om man inte är vaccinerad. Trots att rekvisiten för rätten att stoppa arbetet torde vara uppfyllda så meddelas sällan ett förbud ifrån Arbetsmiljöverket och/eller förvaltningsdomstolarna. I detta arbete görs en analys om varför utifrån samtliga överklag
Bakgrund: Cirka var tredje kvinna i världen har blivit utsatt för våld av en partner och mörkertalet är stort. Trots att identifiering av våld ökar betydligt när vårdpersonal ställer frågor om våldsutsatthet är det många inom vården som inte gör det. Syfte: Att undersöka faktorer som underlättar och hindrar kommunikation för identifiering av kvinnor utsatta för våld i nära relationer. Metod: I en
While grey infrastructure, such as sea walls, have been the traditional method of mitigating coastal hazards there has been an increasing interest in adapting using natural processes, known as Nature-based Solutions (NbS). As with most places in the world, southern Sweden is facing an increase in coastal hazards due to climate change related sea level rise. There is a need to understand the utilit
The European Spallation Source (ESS) has launched a project called HighNESS, with the task of investigating the potential of adding a second moderator system to the facility, with ortho-deuterium (o-D2) being the main material of interest. Another moderator material which could be of interest is hydrogen deuteride (HD). The purpose of this second moderator system would be to provide a high intensi
Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. One field that is particularly affected by this is industrial robotics applications as the control structures implemented and the phy
Owing to the intensive computation involved in the Discrete Cosine Transform during image com- pression, the design of the efficient hardware architectures for fast computation of the transform has become imperative, especially for real-time applications. Although fast computation techniques have been able to minimise the hardware computation complexity to a certain limit, they could further exten
I den här rapporten undersöks möjligheten för att tillverka och använda gjutmodeller tillverkade genom additiv tillverkning, i folkmun kallat 3D-printing. Först görs en grundläggande analys över hur modellerna tillverkas idag och vilka krav som ställs på modellen. Detta innefattar både rena material och hållfasthetskrav, men även mer svårdefinierade krav där man enbart kan resonera kring rimliga aIn this report the possibility for the manufacture and use of molding-patterns made through additive manufacturing methods, commonly called 3D-printing, is evaluated. First an analysis of how the patterns are currently being made and which demands that are put on them will be made. This includes more pure material and load demands, as well as more abstract and hard defined demands. After this the
Famine has played an essential part in the rise and fall of many civilizations. Yet, many considers the plight of famine a phenomenon of the past, reserved for but the poorest parts of the world. In Europe there are plenty examples of famine and hardship during the 19th century. When the most recent famine in Swedish history struck the area of Småland during the 1860s, the mortality distribution d
Bakgrund: Förekomsten av utmattningssyndrom (UMS) ökar i Sverige, vilket leder till allt längre sjukskrivningstider. En längre period med höga nivåer av stress i kombination med otillräcklig återhämtningkan leda till utvecklandet av UMS. Syndromet kännetecknas av tre aspekter: känsla av utmattning, mental distansering och minskad effektivitet. Att vara drabbad av UMS ökar risken för tveckling av e
In this paper a parallel implementation of three methods, Jacobi, Gauss-Seidel and Successive over relaxation (SOR), for solving large and sparse linear systems derived from Poisson type PDEs are investigated in order to find the faster solver method. Workload which is decoupled can be done faster in parallel than sequentially. We use a grid to discretize the PDE and the order of the grid cells yi
From literature review a theoretical research model was developed describing the process for designing a performance measurement system fit for the company culture, strategic direction, and stakeholder perspective. Following the model, the definition of high performance for the department was investigated and success factors were formulated from interview results. These success factors were accord
Between 2014 and 2015 Sweden accepted, by its standards, an unprecedented amount of asylum seekers into the country. The total effect which that had on the country politically and socially may not be fully understood yet but it represented a shifting point in Swedish politics. The image of Sweden as open, tolerant and liberal had been challenged and the political response was a strict tightening o
Bakgrund: Genomförd litteraturöversikt berör sjuksköterskans erfarenhet av att tidigt identifiera patienter med sepsis samt vilka faktorer som påverkar identifieringen. Sepsis är ett globalt problem där 11 miljoner dör årligen. Sjuksköterskan har en viktig roll i den tidigare identifieringen då det ofta är hen som träffar patienten i form av triagering på akutmottagning eller ser patienten på
Education has the potential to play a critical role in the sustainable transformation of society which is needed to limit the consequences of the multiple ecological crises society is facing. While this has been recognised internationally at least since 1992, not a lot has been done within the Danish educational system to address issues of climate change, biodiversity loss, and sustainability with
I Europa påverkas cirka 600 000 personer, inklusive barn, av statslöshet. Även om UNHCR:s #IBelong-kampanj har uppmärksammat frågan och satt ett tydligt mål att statslösheten ska upphöra till 2024, råder det fortfarande tvivelaktigheter kring vilken stat som är ansvarig för att bevilja statslösa barn medborgarskap. Konsekvensen av detta blir en ökad statslöshet bland unga där ingen stat står ansvaIn Europe, about 600 000 individuals, including children, are affected by statelessness today. Although the UNHCR #IBelong Campaign has shed light on the issue and set the goal of ending statelessness by 2024, there is still a lack of understanding as to which State is responsible for granting nationality to stateless children. This leads to the fundamental consequence of stateless-ness, where no
