The use of antenna arrays allows for direction-of-arrival (DoA) estimation in a radar system. The antenna elements in an array are conventionally positioned equidistantly on a grid, but they can also be placed relatively freely to form sparse antenna arrays. These non-conventional layouts could potentially offer improved DoA capabilities. In this work, a particle swarm optimization algorithm has b

This study investigates the impact of classroom conflict and social cap- ital on different measures of human capital accumulation in middle school and high school students from El Salvador. Using class-level measures of mutual enmity and friendship obtained through network analysis and exploiting exogenous variation in the proportion of students who have repeated the school year, I obtain consiste

The partnership and development cooperation between the European Union (EU) and Africa is described as a key priority for the European Commission and their aim is to further strengthen the partnership (European Commission 2020). However, the relationship between the European Union and the African continent has a deep and complex history that has been characterized by colonial ties and unequal powe

Argentina, once among the world's wealthiest nations, has since the 1950s experienced economic turmoil marked by high inflation and currency depreciation. This thesis investigates the historical factors contributing to Argentina's persistent issues with inflation, with particular emphasis on the economic policies made since the 1940s. The study employs a historical institutionalism framewo

Neural networks are effective for solving many complex human-level tasks, one type of neural network often used in imaging tasks is the convolutional neural network (CNN). They can effectively solve problems in areas like image recognition, object detection, and classification tasks. Using a CNN for one of these tasks requires a huge computational cost relative to what a typical algorithm would ha

The increased density of base stations within cities provides improved radar coverage opportunities. The new generation of communication technology has given radar and other functions more room to maneuver. The work presented in this report aims to utilize existing communication base stations to implement radar functions to provide sensing services. In this way, the utilization of current dev

This thesis explores the phenomenon of clothing repair. The fashion industry stands out as one of the most environmentally unsustainable sectors globally, largely due to its adoption of the linear production and consumption model of take, make, and waste. In response to this, the European Union has prioritized textiles in its Circular Economy Action Plan, and within it repair emerges as the most d

Advisor: Elias Bengtsson Purpose: To investigate the effect of commodity price hedging activities had on firm value during the COVID-19 Crisis. Theoretical Perspective: The foundation of this study is built upon the significant theories of Perfect Market Theory, Information Asymmetry, Agency Cost, Risk Shifting, and the emerging concept of ESG. Methodology: The paper utilizes a Two-Way Fixed E

Bakgrund: 2021 stod bygg- och fastighetssektorn för nästan 22% av Sveriges totala utsläpp av växthusgaser. Sedan 2006 finns ett lagkrav om att den som låter uppföra en byggnad även ska ansvara för att upprätta en energideklaration. Lagen syftar till att främja ett effektivt energianvändande för att på så sätt minska utsläppen av växthusgaser. Sveriges el- och energiproduktion står endast för 8 % aIn 2021, the construction and management phase of buildings accounted for nearly 22% of Sweden's total greenhouse gas emissions. Since 2006, there has been a law requiring that whoever constructs a building is also responsible for declaring the energy use of the building. The purpose of the law is to promote efficient energy use in order to reduce greenhouse gas emissions. Sweden's electri

Small Modular Reactors (SMRs) present a transformative approach to nuclear energy, offering enhanced cost-effectiveness and ease of implementation compared to traditional large-scale reactors. This study investigates the dynamic behavior of the steam cycle within SMRs using Simscape MATLAB for simulation. The research focuses on understanding the thermodynamic principles and fluid dynamics that go

I våra försök att förstå fysikens banbrytande forskningsområden, vare sig det handlar om kvantdatorer eller partikel-detektorer, slår vi ofta knut på oss själva. Det verkar därför ironiskt att knutarnas matematik utför ett övertygande ramverk för att förstå komplexa fenomen på nanoskalan. Knutar klassificeras med hjälp av topologiska invarianter - kvantiteter som förblir konstanta under jämna defoThe trimer Su-Schrieffer-Heeger (SSH3) model extends the traditional Su-Schrieffer-Heeger model by incorporating an additional lattice site per unit cell. Although it lacks chiral symmetry, the SSH3 model exhibits bulk-boundary correspondence (BBC) with topologically protected, localized edge states under open boundary conditions. This thesis investigates non-Hermitian phenomena in the anisotropic

Syfte och forskningsfrågor: Studiens syfte är att undersöka självutcheckningskassornas roll i kunders värdeskapandeprocesser och skapa djupare förståelse kring självserviceteknologiers inverkan på kunders värdeskapande och köpupplevelser. Studien undersöker specifikt självutcheckningskassor i klädbutiker, en kontext som är relativt outforskad, där det även rapporterats om flera utmaningar för kund

Ultrasnabba laddningsmätningar i kvantsystem Detektorer byggda med olinjära mikrovågsresonatorer möjliggör ultrasnabb avläsning av kvantkomponenter. Dessa detektorer är av stort intresse för utvecklingen av kvantdatorer. Framtidens kvantdatorer forskars om idag. Deras minsta beståndsdel - kvantbiten - har flera implementeringar gjorda med supraledande komponenter. I supraledande kvantkomponenterThis thesis explores fast charge detection, enabled by the use of quantum dots and non-linear high impedance resonators. In particular, the non-linearities of the resonator are utilized to yield a strong readout from the quantum dot detector. With a strong signal, faster integration times are possible. One of the most useful techniques for fast electrical readout is measuring impedance changes. Th

This thesis examines the development and integration of soft skills into the formal and non-formal education systems of Azerbaijan, as well as evaluating their influence on the employability of young individuals. Through qualitative interviews and secondary data analysis, the study finds that while formal education in Azerbaijan mainly focuses on imparting academic skills, non-formal education pro

Undersökning av inomhusmiljön i Bostadshus i Kurdistan med förslag på förbättringar Av Zahir Rashid Ibrahim Sammanfattning Den varma sommarsäsongen i Kurdistan är mycket lång och omgivningstemperaturen är cirka 45 ˚C. Byggnader kyls ner med luftkonditioneringssystem på sommaren och värms upp med eldrivna eller oljedrivna värmesystem på vintern. Oljedrivna placeras oftast i vardagsrummet Examination of indoor environment in dwellings in Kurdistan with suggestions on improvements By Zahir Rashid Ibrahim Summary The hot summer season in Kurdistan is very long and the ambient temperature is about 45 ˚C. Buildings are cooled by air conditioning systems in the summer and heated with electric or oil-fired heating systems in winter. Oil-driven are usually placed in the living roo
