APTM and GRID signal processing and Errant beam detection at ESS

The European Spallation Source (ESS) will be the world's most powerful next-generation neutron source. It will deliver a high-energy proton beam to the target with a high degree of control. With many components operating at their engineering limits, instrumentation must detect errant beam conditions and suppress proton beam production. One of the beam diagnostic instruments installed will be A

Characterization of InAs-Al semiconductor-superconductor hybrid devices

Olösliga problem blir lösbara med framtidens kvantdatorer! Under 1900-talet gjordes oerhörda framsteg i vår förståelse av kvantmekaniska fenomen, men för varje besvarad fråga väcks två nya. Många högaktuella frågor, och mål, gäller förverkligandet av kvantdatorn, där en av de främsta frågorna är: vilka kvantmekaniska fenomen ska utgöra grunden för kvantdatorns grundkomponent (en ’qubit’)? AlternatIn this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. The contact quality assessment is based on parameters extracted via electrical characterization performed mK temperatures in

Government intervention on talent attraction and integration : taking East Lake High-Tech Development Zone in Wuhan as a case

Talent is seen as a critical factor in promotingregional technological and economic development. Researches on talent attraction and retention policies have been explored in the western context. However, little has been studied in the Chinese talent attraction and retention policy yet. In the meantime, many Chinese cities have implemented talent attraction policies to attract talented workers. The

Climate innovations in the financial sector

A green transition requires to drive public and private capital towards investments in line with environmental norms. Scholars are constantly looking into the performances of sustainable finance and how to measure them. Yet, the perspective from financial firms on climate finance has hardly been studied. This research addresses this gap by offering a qualitative analysis of Swedish financial firms

Telomere length predicts reproduction investment in a migratory songbird

Telomeres have an important role in cell replication and maintenance and are known to shorten at each cell division. They have been linked to lifespan and mortality in wild populations, and induced stress and environmental conditions are thought to accelerate telomere shortening which may lead to shorter lifespan. The ‘disposable soma’ theory of aging, predicts that investment in reproduction will

Servicelandskapets möjligheter för butikers överlevnad av covid-19 krisen: En kvalitativ studie om strukturella förändringar, till följd av covid-19 pandemin 2020.

: I mars 2020 ställdes världen på ända då WHO utnämner covid-19 som en pandemi. Handeln, som sedan tidigare redan står inför stora utmaningar, tvingas ställa om. För den fysiska handeln medför detta behov av att förändra den fysiska miljön inom vilka kunder och medarbetare vistas, för att kunna säkerställa social distansering. Med utgångspunkt i detta syftar studien till att ge en mångfacetterad b

Self-organizing Maps for Digital Pre-distortion

Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. Among those, the digital pre-distortion tends to be the m

Connected Health for Patients Diagnosed with Prostate Cancer

Prostate cancer is one of the most commonly diagnosed diseases among men, both in Sweden and the US. It is a consuming disease that tears on both the patient and his relatives. The different stages of disease are many, as are the different treatment options and drugs. New diagnostic techniques are constantly being developed and more imaging methods become available. As new digital techniques evolv

Staycation möter demografi - En kvantitativ studie om staycation och hur det kan fungera som ett uttryck av kulturellt kapital

Syfte: ​Tidigare forskning har påvisat att att den fysiska distansen mellan hemmet och semestern måste minskas. Staycation föreslås därför vara ett mer hållbart sätt att semestra på då det syftar till att semestra i närheten av sitt hem istället för långväga resor. Däremot har fenomenet staycation fått olika innebörder på internet och i det fåtal forskningsstudier som finns. Trots att staycation ä

What’s the problem with Women not Working? A Critical Analysis of the Skill India Development Mission & Explanations on Female Labor Force Participation

This study analyses the Skill India Development Missions ways to increase female labor force participation and economic development. Previous research finds that the low rates of women working in India, in times of rising economic growth and education, are driven by supply, demand, or data related factors. This study contrasts the explanations by adopting a ‘what’s the problem represented to be’ a

(Un)making Strangers? Exploring integration discourse in local projects

This thesis uses a phenomenological approach to explore attitudes and meanings of integration work made by local project workers and volunteers. Relating to previous literature which critiques ‘integration’ as a highly problematic concept, as well as drawing on insights from social theory and the concept of imagined communities, the study contributes to shed light on citizens’ making of an integra
