Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. A commercial drone propeller from the manufacturer APC Propeller has been modified with different forms of

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 contribute with an understanding of what role AI has, and might have, in strategic decision making processes. The literature review of the study builds upon research within Resource Based Theory, Strategic Decision Making Theory and is supported by technical reports on Large Language Models. It is a qualitative single case study with empirical data collected from si

Vi hittar planeter ̈överallt vi tittar i Vintergatan. De ser olika ut var man ̈an kollar. Men det finns några platser där planeter verkar vara obefintliga: i klotformiga stjärnhopar. Dessa innehåller hundratusentals stjärnor som, på grund av gravitation emellan dem, hålls ihop och bildar ett stjärnsystem som sträcker sig över hundratals ljusår i diameter. Än så länge har bara en exoplanet hittats This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. To determine the stellar type, an HR-diagram wa

Syftet med detta arbete var att undersöka olika parametrars betydelse för instabilitetsfenomen i ett underspänt balksystem av limträ. Arbetet syftade även till att undersöka den komplexitet av modellering som krävs för att nå tillräcklig noggrannhet med avseende på instabilitet. Komplexitet i modellering avsåg i detta arbete typ av beräkningsmodell avseende geometrisk representation (1D, 2D, 3D) oFor buildings where high demands are placed on open space, pre-tensioned glulam trusses have become a popular solution. Such a truss is often optimized to be material-efficient when subjected to loading within the plane of the truss itself. However, material-efficient and slender roof trusses can be highly sensitive to loads and unintended movements perpendicular to the loading plane. Poor choices

This thesis examines the relationship between university education quality and young graduates' labour outcomes. The thesis employs a micro-level data analysis based on the National Survey of Households (ENAHO) and information from the National Board of University Education (SUNEDU). Linear Probability Models and an OLS multivariate regression are used to assess the effects of the quality univ

Bakgrund: Ökad invandring i Sverige har ökat tolkbehovet i vården. Vid avsaknad av tolk används familjemedlemmar och tvåspråkig vårdpersonal som tolkar samt icke-verbal kommunikation, vilket påverkar kommunikation på olika sätt. Syfte: Att belysa betydelsen av tolksituationen inom hälso- och sjukvård avseende samspelet mellan patient, familjemedlemmar och sjuksköterska. Metod: Litteraturstudie med

Barns rätt till en god utemiljö och utevistelse i förskola är inte föremål för tillsyn. Svensk miljölagstiftning är inte tillämpbar för att kontrollera att barn får sina behov av en god utemiljö och en regelbunden utevistelse tillgodosedda enligt rättspraxis. Kommunala miljönämnder runt om i landet har i flera decennier arbetat för att ställa tydliga krav på utemiljön som står till förskolebarnToday, 86% of children between the age of 1 and 5 are enrolled in preschools in Sweden. The outdoor environment is important to support children’s development, health, and wellbeing. Children’s perception of what an appropriate outdoor environment is often differs from what adults consider to be a god and healthy outdoor environment. The aim of this study is to confirm the gap in supervision

Förbättrat ultraljudsprogram, helt utan ultraljudsbilder Med hjälp av ultraljud, nanopartiklar och en magnet finns det ett nytt sätt att se vilken behandling cancerpatienter ska få. För att metoden ska kunna användas i sjukvården så snart som möjligt behöver ultraljudsmaskinen testas med syntetiska ultraljudsbilder. Ett nytt sätt för att se om cancer spridit sig från den ursprungliga tumören tilClinical trials are difficult to access and of high importance when evaluating biomedical software. Without data which is comparable to the intended input data of the final product it is nearly impossible to fully evaluate its function. One way to evaluate ultrasound detection software is the use of phantoms. Another is the creation of synthetic data. In this report one method of creating syntheti

The growing complexity of cloud native applications has necessitated the intro- duction of operators to the container orchestration tools’ suite of components. Operators affords developers the ability to encode domain knowledge and make fine-grained controllers for their Kubernetes clusters, radically extending the range of feasible applications to host. Operators are however vast software entitie

Nu kommer kraven för att återställa naturen – hur ska företagen lösa detta bortprioriterade ämne? Planetens alla livsavgörande funktioner såsom matförsörjning och materialtillgångar är beroende av en välmående natur. Funktioner som just nu håller på att gå förlorade på grund av en global massutrotning av planetens arter. Äntligen börjar makthavare lyfta blicken och inse att det inte bara handlar oBiodiversity is fundamental for human well-being, and we depend on nature’s ecosystem services for our survival. Today, biodiversity loss occurs at an accelerating rate and the number of endangered species is higher than ever. Despite this, biodiversity loss has long been overshadowed by the climate issue. However, the issue of biodiversity is now receiving more attention and new frameworks and po

This study investigates the extent to which news affects individuals' inflation expectations through an innovative experimental design. The results show that news treatment significantly affects inflation expectations, with varying degrees of impact observed across different inflation regimes. Furthermore, the study reports differences between sexes, with women reacting more strongly to news t

The Arka is a new re-constructed rocking chair that brings a more aesthetic piece of furniture to your home, at the same time reducing stress, anxiety, pain and discomfort. Since the outbreak of Covid-19 we were forced to work from home, this meant that all of our stress from work/ school were now in our safe and calming home. This trend is still shown today. The main focus of this bachel

The aim of this paper is to evaluate potential leading indicators of a recession in Sweden. To answer the question potential leading indicators are first identified with previous findings in literature and with the current state of the Swedish financial system as background. Then these variables will be included in a probit regression at different forecasting horizons. The horizons are one, two an

BAKGRUND: Kraven på sjuksköterskan ökar ständigt, vilket kan leda till en osäkerhet i yrkesrollen. Hur livserfarenheter har påverkat yrkestryggheten belyses i denna studie som tar avstamp i KASAM-teorin med begreppen begriplighet, hanterbarhet och meningsfullhet. SYFTE: Att belysa sjuksköterskors upplevelse av livserfarenhetens betydelse för yrkestryggheten. METOD: Sju sjuksköterskor inom somati

Article 17(1) of the Market Abuse Regulation (MAR) mandates that an issuer shall publicly disclose “inside information” which directly concerns the issuer as soon as possible, with the concept of “inside information” defined in art. 7 of MAR. This obligation is often referred to as the ad hoc disclosure requirement and it‘s perhaps the most crucial obligation issuers have to comply with when their

Differentiation is something that can easily be seen in today’s world, almost everywhere in companies, brands, people, products. It is simply ubiquitous. Cosmetics is an industry in particular where product differentiation in particular now plays an increasingly salient role in allowing firms to stand out from competition; a competition that will never cease to exist. This study explores the very
