This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. This spectrum is subsequently modeled to pass thr

Detta examensarbete utforskar det relativt outforskade fenomenet venture studios (även känt som bolagsbyggare, venture builders och startup studios), vilka är företag som systematiskt bygger bolag. Trots att antalet venture studios ökar så är akademisk forskning kring ämnet relativt begränsad. Denna studie syftar till att fylla denna kunskapslucka genom att genomföra en fallstudie på sex svenska vThis master's thesis explores the relatively unexplored phenomenon of venture studios (also known as venture builders or startup studios), which are companies that systematically and concurrently build startups. Despite their growing popularity, the academic literature on how venture studios operate is still limited and no structured and extensive description of the business model appears to e

Precis som arkeologer gräver i jordens historia finns det astrofysiker som gräver i Vintergatans förflutna. Det finns ingen fullständig bild över Vintergatans evolution. Därför är galaxformationen ett relevant ämne inom astrofysiken. När man grävt i ljusspektra och rörelsedata av stjärnor i vår galax har man funnit att många stjärnor har sitt ursprung utanför Vintergatan. En galax som rör sig geThe Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. In this project we create candidate lists of stars that are likely to originate from past merger events experienced by the Galaxy, usi

The aim of this study was to examine how youths’ behaviors are portrayed within Swedish administrative courts verdicts regarding compulsory care in 3§ LVU (the Care of young person act) and to examine potential gender differences. The study was conducted with a qualitative research method through a thematic analysis of court verdicts. The selection for the empirical material was based on the follo

Strategi har länge varit ett av de viktigaste åtagandena för en organisation då det ger riktning och skapar syfte för framtida aktiviteter. För att på bästa sätt utnyttja sina resurser försäkra sig om att ta rätt beslut använder sig organisationer av beslutsstödsystem. Användningen av beslutsstödsystem (DSS) på en strategisk nivå har potentialen att höja en organisations konkurrenskraft och framgå

Filosofin ''Lean construction'' förklarar hur värdeskapande kan maximeras till följd av samarbete. Studiens syfte är att utforska kontraktuella detaljers påverkan på samarbete i byggsektorn. Den är utformad efter en kvalitativ metodteori där fokus inte bara placeras på handlingar, utan även deras innebörd. Målet var att skapa ett begrepp kring fenomenet samarbete. För att kunna preThe philosophy of ''Lean construction'' explains how value creation can be maximized as a result of collaboration. The purpose of the study is to explore the impact of contractual details on cooperation in the construction sector. It is designed according to a qualitative method theory where the focus is not only placed on actions, but also their meaning. The goal was to create a c

Accoya: virket som motstår rötsvamparna Att använda trä som byggnadsmaterial har en lång tradition i Sverige, då tillgången är god. Nu har det återigen fått ett större fokus i hopp om att minska byggsektorns klimatpåverkan. För att utöka träets användning måste dess problem med fukt begränsas, där det största problemet är rötsvampar som bryter ned träet och gör det svagare. En vanlig metod är attWood is one of the oldest building materials, which have recently gained more focus in aneffort to reach net zero emissions. The mechanical properties of wood are dependent on the moisture content, and a high moisture content can also lead to biological attacks from decay fungi. To avoid biological attacks the wood must be protected from moisture, and a traditional method is to pressure impregnate

Introduction: Antibiotic resistance is rising globally, increasing the demand on new antibacterial substances. Background: Studies suggest that lignin exhibits antibacterial properties, however this property is unexploited commercially. The valorization of lignin is difficult due to its complex and variable structure. Aims: This study aims therefore to fractionate lignosulfonate lignin (LSL) into

Electric road systems can be defined as a system transferring energy from a road to an electric vehicle while the vehicle is in motion, either to power the vehicle’s movement or to charge its batteries. This thesis aimed to investigate how this relatively new technology of electric road systems could be implemented in a port. The research was conducted by having a two-fold research purpose. Firstl

After Edward Snowden exposed the mass surveillance practices of the US intelligence services in 2013, personal data protection has taken a prominent position in the legal systems of various jurisdictions, including the European Union. The Safe Harbour agreement regulating the flows of personal data transfers between the US and the EU at that time was soon invalidated by a ruling of the European Co

Purpose: The purpose of the thesis is to investigate if deal completion probability is associated with the stock market’s initial reaction to the M&A announcement. Furthermore, the study aims to explore if other characteristics have a relationship with deal completion, and if they have a moderating effect on the relationship with deal completion and the stock market’s reaction. Methodology: We

Recently, the notion of omnichannel retailing and marketing attracted widespread interest in academia, complemented by miscellaneous efforts of retailers to establish omnichannel brand communication. Following these attempts, global retailers face the risks related to brand communication failure and misrepresentation of brand values. However, the research is still limited in terms of differences i

In this thesis we introduce the concept of a p-adic analytic pro-p group. To do so we discuss important theorems and concepts connected to more general types of groups, these include profinite groups, pro-p groups, powerful p-groups, powerful pro-p groups and uniform groups.

Neither did Hitler abhor the law, nor the legal profession. What Hitler abhorred was the law and legal profession that were not aligned to his worldview. So critical was the law, the legal order, the legal profession to Hitler that he himself, for instance, commenced to construct his regime thanks to the Article 48 of the Weimar Constitution. This work is both an examination and an interpretation

Inflationen har stigit kraftigt de senaste åren runt om hela jorden. Stigningen kom oväntat och överraskade både centralbanker och kapitalförvaltare. Detta har lett till kraftiga ränteökningar för att försöka dämpa inflationen till lägre nivåer. Kanske hade det gått att undvika dessa kraftiga ränteökningarna om man hade haft tillgång till estimat av inflation på förhand. Vi undersöker i detta exDifferent models were developed with the aim of nowcasting inflation at a daily basis with high frequency variables, while using real-time data to avoid look ahead bias. Both popular machine learning models such as Random Forest and XGBoost, and more traditional models such as UMIDAS and Almon distributed lag models were used to make the nowcasts. The MIDAS framework was utilized as a way of handl

The topic for this thesis is corruption as an obstacle for development. More specifically the research looks at how corruption affects one of our most important agents of change; the Civil Society Organizations (CSOs). The specific research question guiding the study is “How do civil society professionals perceive that corruption in their operational environment affects their ability to achieve th

For many cultures, architecture represents more than just physical structures. It signifies culture, affiliation, and ownership within a specific society. However, in many African contexts, various coercive and assimilative historical, socioeconomic, and cultural phenomena, such as colonialism, have caused a divergence between the people’s architecture, way of life, and culture. Furthermore, the i
