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

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

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

Införandet av uppblåsbara och mekaniska vädertätningarna har sänkt energikostnader genom att eliminera en av de största värmeförlusterna i lagringscenter. Dessa vädertätningar kostar tio tusentals kronor att installera och finns nu i varje lager runt hela Sverige. Denna kostnad gör det dyrt att ersätta en vädertätning ifall den skadas. Största orsaken till att dessa vädertätningar blir förstörda eWith the introduction of inflatable dock shelter bags and curtain docks, money and energy has been saved in solving one of the major heat losses in distributions centres. These dock shelters are now almost on every dock across Sweden and each cost thousands of kronor to install. Therefore, it is expensive for distribution centres to replace them whenever they break. ASSA ABLOY have found a common

Energilösningen för Framtiden: Vattenpumplagring & Vindkraft Genom åren har användningen av fossila bränslen minskat, samtidigt som vi sett en ökning av förnybara energikällor som vindoch solkraft. Sverige står dock inför en utmaning: vindens oförutsägbara natur skapar problem för elnätets stabilitet. Denna rapport utforskar möjligheterna kring el-lagring genom vattenpumplagring kopplat till The introduction of the Renewable Energy Directive 2009, increased the renewable energy sources (RES) in the European Union (EU) and especially Sweden. Given the uncontrollable nature of weather patterns, energy generation is likely to become more volatile, thereby elevating the risk of curtailment and negative energy prices. The electricity demand in Sweden is also poised to rise sharply in the u
