The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. In contrast to more conventional n-type material system, however, p-type quantum devices benefit from

Denna studie är en forskningsöversikt i ämnet övergång mellan förskola och skola. Metodvalet innebär att forskning i ämnet sammanställts och analyserats utifrån likheter och olikheter i studiernas utfall. Sammanlagt fjorton studier har använts i genomförandet av den här studien. Syftet med föreliggande studie var att undersöka de processer som omger barnet i den pedagogiska övergången mellan försk

The quantity of biomarkers, which are proteins in this case, in ovarian cancer (OC) tumor and immune tissue regions of interest (ROIs) were measured with the new technology Digital Spatial Profiler (DSP). These measurements were used to construct regression models on the biomarkers to predict for two clinical parameters; tumor type (”Type 1” vs ”Type 2”) and the immune infiltration type (”Cavities

The COVID-19 pandemic revealed the fragility of the global food system and its existing inadequacies in achieving food security, providing jobs, and ensuring environmental sustainability on various regimes around the world. Through a qualitative thematic-textual analysis, this thesis uses a case study of New York City to identify themes of actor expectations, either explicit or implicit, on how to

The audiobook is a format that has invaded the Swedish book market. Through it’s format it has made literature available to more people, just like the paperback did when it was first introduced on the market. By simply having the book on your phone, it’s easier than ever to take it with you and can be played while the listener does other things, such as traveling, cleaning or performing other acti

Purpose: The purpose of this study is to develop an understanding of consumers' perception of heritage in luxury brands online. This will be investigated from a consumer perceived value perspective, with regard to the following aspects of value; social, economic, functional and affective. Methodology: An epistemological and ontological foundation guides the research approach of qualitative so

Learning attainments of children in Peru have remained at low levels according to international assessment. The country has carried out several educational policies from different perspectives aiming to raise the school achievements of students in primary and secondary education, nevertheless the levels of satisfactory attainments at the regional level show severe contrast between less and more co

This thesis deals with radar data for the purpose of moving target classification in the context of surveillance. The radar data in question comes in the form of point-clouds represented as frame-wise histograms with several channels and we seek to improve upon an existing cross-entropy based deep learning classifier using supervised contrastive loss. We find that the embeddings output by supervi

Förstärkt verklighet (AR), augmented reality på engelska, har på sistone fått stor uppmärksamhet från kända applikationer som Pokémon Go och Snapchat. AR har dessutom blivit alltmer populärt som dels mätverktyg men också för att instruera och hjälpa användare som jobbar med komplexa arbetsuppgifter. Huvud-burna AR-glasögon kan dessutom ha stor potential att assistera människor vars händer är upptaAugmented Reality (AR) has lately gained a lot of momentum with popular applications such as Pokémon Go and Snapchat. Also, AR is becoming increasingly popular as a supportive tool for measuring objects and instructing users who are struggling with complex tasks. Moreover, head-worn AR glasses can have the potential of assisting people who needs their hands elsewhere or are unable to use their han

3D city models are valuable tools for visualization and analytical purposes in the urban environment. A popular format for city models is CityGML, an open data model that can be used for storage and exchange of 3D city models. However, using city models based on CityGML has appeared to be a challenge as there is a limited number of software applications that are able to read them. Complexity in Ci

Smartphones are an increasingly important part of our lives. As services that treat sensitive information are found on most modern phones, there is a growing need for security. The common approaches of entering a PIN-code or some pattern when accessing an application on the phone is not necessarily sufficient, as they are vulnerable to different types of attacks. The embedded sensors of modern sma

The discussion of human activities exploiting natural resources and their environmental impact has gained more traction throughout the past decade. Especially the role corporations play in these developments has caused a shift within corporate strategic considerations. As a result, today, many companies assume increasing responsibility to improve their sustainability performance. Large, internatio

Policy makers in most European countries have in recent decades reformed their pension systems with the aim of increasing labor market participation among older workers to solve the problem of an ageing population. The question arises whether delayed retirement is a sustainable solution or if it comes at the cost of certain groups in society. The reasons an individual might choose to retire are no

While there have been numerous research papers defining and discussing high technology startup success, there is a lack of unity what the recipe for success is. Due to lack of market orientation being one of the most common reasons for startup failure, combined with the essentiality of having a strong technology base in a high technology environment, there is an interest to study their intersectio

This Master's thesis sheds light on influential actors in global regimes. Following the concept of Fuenfschilling & Binz (2018), it aims to answer the question of how global regime rationalities diffuse and where they develop. Based on global elite literature, a new conceptual perspective of studying diffusion of global regime rationalities is introduced. The framework focuses on interlock

Several studies and actors have emphasized the role of Renewable Energy Communities as collective citizen initiatives enhancing the decentralized, low-carbon energy transition. Despite the social, environmental, and economic benefits, several changes in the energy policies in Germany have led to a decrease of newly registered Renewable Energy Communities. Previous financial measures have failed to

In this thesis we have evaluated methods for doing full-text searches in patent documents. The aim of patent searches is to find evidence and relevant documents when an invalidity search is done on a patent. With three different language models, BOW, SPECTER and SBERT, we have evaluated the results of two different text segmentation methods, greedy sentence split and paragraph split, and two dif

Utbrottet av den globala pandemin våren 2020, inneburit omvälvande förändringar för i stort sett alla människor och verksamheter. Privilegier som fri rörlighet och mötesfrihet har sedan utbrottet bytts ut mot strikta restriktioner i de flesta länder vilket drivit många branscher in i krisläge och därmed förändringsarbete. Fastighetsbranschen är inget undantag. Sedan folkhälsomyndigheten rekommenSince the outbreak of the pandemic early 2020, the world has experienced disruptive change in many of its foundations. Privileges as free movement, the freedom of assembly and simply being able to go to the movies have been replaced by strict local and national policies, limiting humans and companies. The Covid-19 agenda has forced a lot of businesses into crisis mode with transformation as a cons

The way of working of social work administrators assessing the needs of intervention for people with physical or mental disabilities was examined, in two middle-sized Swedish municipal settings. Also their opinions about the organization´s need to stay efficient and cost-effective was examined. Aim: Their mindset towards the (LSS) law was studied, how they interpret and apply it´s purposes in the
