Monte Carlo simulation is a numerical method that can simulate complex physical systems and is widely used in the field of medical optics. For example, the Monte Carlo method was used to evaluate the effectiveness of near-infrared spectroscopy (NIRS) in the detection of intracranial hematoma (ICH). However, due to the relatively complex brain structure, the current simulation model is relatively s

This thesis examines the spatial relationships between tenure type composition and the crime rates of property and violent crime, using data at the census block level for Chicago, Illinois. A multi-scalar k-nearest neighbor analysis is employed to model patterns of tenure type composition at four different scales of aggregation, by constructing individualized neighborhoods for each census block.

I det här kandidatarbetet undersöks kulturer för att ta reda på vad som influerar deras möbler. Två kulturer studeras i det här projektet: kulturen i Kina under Mingdynastin såväl som den nutida kulturen i Sverige. Detta för att finna deras likheter och skillnader. Det ska sedan appliceras på en ny serie möbler. Projektet är av en mer utforskande karaktär än ett klassisk designprojekt, dock följerThis bachelor’s project investigates what influences furniture within different cultures. Two cultures are studied, the culture in China during the Ming Dynasty and the culture in contemporary Sweden. This is to understand their commonalities and in which ways they differ. This is then to be applied to a series of furniture. The project has a more explorative nature, however, it still follows a tr

With his notion of original affirmation, Paul Ricoeur wishes to reinstate the primacy of being over nothingness, joy over anguish, and affirmation over negation. Having adopted the term from Jean Nabert, he draws from the tradition of French reflective philosophy to formulate his conception of the originally affirmative nature of existence. Ricoeur argues that positive values can be found in and t

Malaria är en sjukdom som drabbar hundratals miljoner människor över hela världen och står för flera hundratusentals dödsfall varje år, till mesta delen i Afrika. Malaria orsakas av malariaparasiter av Plasmodium-släktet. För att överleva, konsumerar malariaparasiter hemoglobinet som finns i våra röda blodkroppar, och som biprodukt bildas ett toxin som parasiterna polymeriserar för att oskadliggörMalaria is a life-threatening infectious disease that affects millions of lives annually. Malaria parasites can develop resistance against existing drugs, which forces the concept of continuous development of new drugs that can overcome the resistance. Organometallic complexes have met great success as antitumor drugs, and the ongoing interest of organometallic drugs sets the light for more accomp

Academic interest in economic inequalities has investigated the patterns of inequalities perpetuated by colonial rules across Africa over the past two decades. The findings highlight that, at a country level, there are biased investment policies favoring European settlers and encouraging the extraction of resources. Considering the importance of regional inequalities in Tunisia in the modern er

Bilingualism has become increasingly prevalent globally, with about half of the world's population being bilingual by 2012. This growing trend has prompted cognitive research to explore the effects of bilingualism on executive functions. The Bilingual Advantage (BA) theory posits that bilingual individuals experience enhanced cognitive abilities due to their practice in managing multiple langu

Morgondagens energisystem står inför stora utmaningar och snabba förändringar både i Sverige och i världen. För att nå ambitiösa klimatmål ses elektrifiering som en viktig lösning på problemen, där Svenska Kraftnät räknar med en nära fördubbling av efterfrågan på el till 2045. Denna ökning, till stor del driven av förnybara energikällor som är svårare att planera och pronosticera, innebär betydandThe energy system of tomorrow faces major challenges and rapid changes both in Sweden and worldwide. To achieve ambitious climate targets, electrification is seen as a key solution, with the Swedish TSO projecting a near doubling of electricity demand by 2045. This increase, driven largely by renewable and intermittent energy sources, poses significant challenges for grid stability. Consequently,

This project delves into two prominent yet occasionally contentious markets: alcohol and fragrance. The overarching goal is to intertwine these industries. The project aims to navigate these complexities by research and exploration.

Föreställ dig att du går ut ur ditt hus och slår ett mynt. Får du huvuden går du ett steg åt vänster och får du svansar går du ett steg åt höger. Om du fortsätter denna process, är det garanterat att du kommer tillbaka hem? Det är möjligt att du bara vänder på huvudet och därför aldrig återvänder hem. Det visar sig att även om detta är teoretiskt möjligt är sannolikheten för att det händer noll, oShowing when random walks are transient or recurrent is the central topic we investigate in this thesis. To be able to find the conditions of a random walk, we develop techniques gained from knowledge about electrical networks developed from Snell and Doyle’s “Random Walks and Electrical Networks” (1984). We aim to use these techniques from Snell and Doyle’s work to be able to find conditions of r

Seagrasses provide valuable ecosystem services, benefitting both marine species and humans by providing coastal protection and erosion control which is significant as 898 million people lived in low-elevation coastal zones in 2020. However, seagrasses worldwide have been declining and in Sweden, the eelgrass Zostera marina has decreased heavily since 1980. One cause for seagrass loss in temperate

In March 2018, the Turkish armed forces, together with the Syrian National Army, seized control of the Syrian district of Afrin bordering Turkey as a result of the military offensive called 'Operation Olive Branch'. This takeover marked the beginning of Turkish military rule of Afrin, which has now extended over six years. Afrin’s case is a significant example of Turkey's broader forei

Den svenska dataspelsbranschen har historiskt sett varit starkt mansdominerad, och trots en ökad representation av kvinnor kvarstår stora utmaningar när det gäller jämställdhet, särskilt i högre positioner. Syftet med denna studie är att undersöka om det finns hinder, såsom ett "glastak", som hindrar kvinnor från att nå ledande roller inom branschen, samt att utforska vilka strukturer so

Multitasking, increasingly prevalent with the rise of digital tools and fast-paced environments, has become integral to daily life. Although it enhances our ability to manage several tasks simultaneously, it also poses challenges to learning and information acquisition. This study investigates how multitasking impacts the formation of relational memories, focusing on the role of eye movements. Par

As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip

The global tourism industry faces significant sustainability challenges, with environmental degradation and social inequities threatening its long-term viability. This is particularly critical for developing urban centres like Lagos, Nigeria, where rapid tourism growth has intensified environmental and social pressures.
