En hybridpark bestående av vind- och solkraft förbättrar vätgasproduktionens prestanda jämfört med ifall kraftslagen agerar separat och kan dela på samma infrastruktur. Detta examensarbete är en förstudie som granskar möjligheten för två vindkraftverk med en effekt på vardera 2 MW att kompletteras med en solcellspark för att bilda en hybridpark med vätgasproduktion. Förstudien undersöker dess teknA hybrid power plant (HPP) existing of wind- and solar power improves the performance of the hydrogen production compared to the stand-alone alternative and can share infrastructure. This thesis views the possibility for two wind turbines with 2 MW power each to be combined with solar power to form a HPP with hydrogen production. The thesis investigates the plant’s technical, economic and permits

Fast och slow fashion, skillnader och likheter i användningen av återvunnen syntetisk fiber. Modeindustrin är bland de industrier som bidrar till de största miljömässiga problemen vad gäller utsläpp av växthusgaser, kemikalie- och vattenanvändning samt ohållbara avfall. Nu står de inför en förändring i att bli en mer hållbar industri, pådriven både från statligt håll samt från konsumenters håll.The fashion industry is one of the largest contributors to environmental issues and has a significant part of plastic production due to the use of synthetic fibres. Much scientific research indicates that the fast fashion model is a significant part of using synthetic fibres; however, slow fashion brands are also using the fibres. Communicating products' sustainable footprint has become an ess

The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. This project can serve as the first step in the process of building such a spectrometer. This spectrometer takes the core principle

The purpose of this thesis is to investigate how Enterprise Risk Management (ERM), with an emphasis on risk aggregation, is conducted in practice. The thesis starts with a scoping study to review available literature on ERM. The findings from the scoping study show that literature focus on how ERM impacts certain financial variables, e.g. return on assets, return on equity, and firm value of organ

This project is an investigation of natural materials and sustainable construction techniques. It is important to implement sustainable materials to help protect the environment. Opportunities in agricultural waste were found and wheat straw in particular. Wheat straw as a building material was approached by researching its historical and future areas of use. The project presents two chairs that

Using music as a tool for teaching a foreign language has been shown to positively affect the language learning process (Balčytytė-Kurtinienė, 2018; Cañete García et al., 2022; Heidari- Shahreza & Moinzadeh, 2012), and this essay suggests that authentic English songs can be used in the teaching of EFL in lower-secondary school in Sweden to efficiently meet many aspects of the syllabus. Therefo

We utilize data from the Survey of Health, Ageing and Retirement in Europe (SHARE) 1 to investigate the impact of retirement on mental health in a multi-country setting. To deal with endogeneity in retirement behaviour, we employ an individual-fixed effects IV strategy where pension eligibility thresholds at which financial incentives to retire are exploited to predict retirement behaviour. The co

Bakgrund: Att vara förälder till ett barn eller ungdom med autism ställer höga krav på föräldraskapet och påverkar aktivitetsmönstret. Stor del av forskningen fokuserar på svårigheterna som följer med diagnosen men kunskapen om vad föräldrarna gör för att främja sin aktivitetsbalans är begränsad. Syfte: Att kartlägga hur föräldrar till barn och unga med autism upplever och hanterar sina barns över

The aim of this essay is to gain insight into how audiovisual input is used in the classroom as a tool to teach vocabulary. This is done by exploring the use of digital audiovisual input in the form of film, documentaries, short videos, and cultural video content in the English as a foreign language (EFL) classroom. Audiovisual input contains a few key elements: audio, video, and on-screen text; t

Viktstigma inbegriper negativa stereotyper och negativa attityder riktade mot individer med obesitas eller övervikt. Internalisering av viktstigma, en process som också kallas självstigmatisering, kan ha negativa konsekvenser för hälsan. Det finns för närvarande inget instrument för att mäta självstigmatisering i en svensk kontext. Att utveckla ett sådant instrument skulle kunna vara avgörande förWeight-based stigma includes negative stereotypes and negative attitudes directed toward people with obesity or overweight. When internalized, a process also referred to as self-stigmatization, it can have detrimental effects on health. There is currently no instrument to measure internalized weight bias in a Swedish context. Developing such an instrument could be a vital step in improving obesity

By supporting the economy of Ukraine, the Association Agreement between the EU and Ukraine is thought to have played an important role in EU’s support during recent crises. The agreement was signed in 2014 and included a deep and comprehensive free trade area (DCFTA). By opening the markets, DCFTA is expected to increase exports between the countries and thereby lead to economic growth. Since the

The main objective of this study is to examine whether monetary policy and lockdown of the Covid-19 pandemic together with social distancing, have had a significant impact on the economy. In terms of monetary policy, this study primarily focuses on the use of quantitative easing by the Swedish Riksbanken and European Central Bank. The purpose is to observe to what extent Sweden has managed to mode

The thesis reviews research about economic impact of education and overeducation, and also researches about education, inequality and suicide in Japan. The thesis describes Thurow’s job competition model, Spence’s job market signaling model and Tsang and Levin’s production model. By using descriptive quantitative methods, it shows that Japan has overeducation problem brought by mismatch between ed

Fördelarna med diversifiering har bevisats om och om igen inom portföljvalsteori men hur en portfölj ska konstrueras är inte helt tydligt. I en studie av DeMiguel et.al (2009) kom författarna fram till slutsatsen att en simpel naiv diversifieringsstrategi fungerar mycket bättre än Markowitz mer avancerade mean-variance modell från 1952. Den här studien avser att svara på frågan, Kan modern portföl

In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. Recently, a higher-order sweet spot was discovered, where the DQD is theorized to have i

The self-evident contradictory governance ideology of the Chinese Communist Party leads to urban-born young middle-class Chinese women struggling between seeking one’s own path with the discourse of ‘individualism’ under the neoliberal market economy and conforming to the traditional role in the family of patriarchal culture. This is reflected in the increasing prominent phenomena of getting marri

The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. Bogoliubov amplitudes are generated using BCS wavefunctions. The Bloc

Av de nästan 200 blottningarna av vulkaniska bergarter som kan ses i Central Skåne Volcanic Province (CSVP) består endast tre av vulkanoklastiskt material. Stratigrafin i dessa avlagringar vars förhållande till underliggande urberg har för första gången beskrivits i en borrkärna (KBH2) från Djupadalsmölla för att bestämma stratigrafin samt avsättningsprocessen, åldern och avsättningsmiljön. BorrkäFrom the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional envir

I ljuset av samtida fynd inom evidensbaserad rekrytering och en uppdaterad polisprofil har Plikt- och prövningsverket reviderat urvalsprocessen till polisutbildningen. Till följd av revideringen är det okänt hur olika delar av urvalsprocessen bidrar till den samlade bedömningen av kandidaters lämplighet. Urvalsprocessen består av fem urvalsmetoder, administrerade i sekventiella steg: kognitiv förmIn light of contemporary findings in evidence-based selection and an updated police profile, the Swedish Defence Conscription and Assessment Agency (SDCAA) have made adjustments to the selection process for police training. Following the adjustments, it is yet to be evaluated how different parts of the selection process contribute to the overall assessment of candidate suitability. The selection p

Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. Martinet (Martinet 1974), where he proved that there should be a dearth of stars with zero angular momenta in the solar neigh
