This thesis examines some of the multiple variations of the previously established Rules of Thumb; which are used in attempting to explain implied volatility sur- faces. Here, these Rules are extensively tested on the Swedish stock market index (OMXS30) using rolling window analysis and linear stepwise regressions with for- ward selection. Data is collected on options at four different maturities
Increasing waste generation levels are presenting a multitude of issues from both low and high- income countries around the world. High levels of greenhouse gas emissions, water contamination and ecosystem endangerment are all concerns that are exacerbated by improper management of waste. Major shifts in the waste management sector are necessary in order to tackle these issues sustainably and for
Syfte: Syftet med studien är att undersöka vilka attityder, utmaningar och möjligheter det finns i branschen gällande förändringsarbetet vid implementering och användandet av ett nytt digitalt arbetssätt. Studien lägger fokus på förändringen av en given process från manuellt skriven pappersföljesedel till digital följesedel för leverantörer av transporttjänster samt åkerier. Frågeställningar: 1.
Bakgrund: Ungefär 90% av patienterna som genomgår anestesi utvecklar atelektaser. Atelektaser kan i sin tur ge upphov till inflammatoriska processer som postoperativt kan leda till lungkomplikationer. Syfte: Syftet var att beskriva vilka av metoderna preoxygenering, PEEP, CPAP, lungrekrytering och låga tidalvolymer som är mest effektiva för att minska förekomsten av atelektaser hos vuxna som genom
In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. In this bachelor thesis, these droplets were numerically stud
A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation. Without the ability to select and enhance a specific sound source of choice while suppressing the background, the hearing aid
The increased capacity of elementary particle accelerators raises the demand for the simulation data of the experiments. One of the bottlenecks in the simulations is the QCD color structure calculation, which is usually treated using non-orthogonal and overcomplete sets of bases. The computational cost could be decreased significantly if orthogonal bases, such as the multiplet bases, were used ins
I Helsingborgs stad, likt i många andra större städer i Sverige, råder det platsbrist samtidigt som grönytor försvinner i takt med att nybyggnationer ökar. Helsingborgs stad har som vision att vara en skapande, pulserande, gemensam, global och balanserad stad för både människor och företag år 2035. Den nya urbaniseringstrenden ställer därmed krav på stadens uppbyggnad och planering. Vidare har gröIn Helsingborg, as in many other major cities in Sweden, there is a shortage of space as green space disappears while new construction increases. The municipality of Helsingborg has a vision to be a creative, vibrant, common, global and balanced city for both people and companies by 2035. The new urbanization trend places a demand on the city's construction and planning. Furthermore, greenery
Can the way we design apartment buildings have a positive effect on our mental welfare and make us feel happier? Bojgatan 1 is an attempt to explore how architecture can help us to feel and live better. With over half of all residences in Sweden being of only one person living in very standardised tried and tested apartment types, could this cultural consequence affect the welfare of these residen
Malaria is a global health issue affecting hundreds of millions of people worldwide and accounts for as much as 405 000 deaths annually. Preventative actions are taken but are seemingly not enough to eradicate the spread. Targeting underlying molecular mechanisms behind the host-seeking behavior of the principal malaria vector Anopheles gambiae, would offer a new approach in the development of an
Water is a large part of life on earth and is also a large part of the human body which is why it is so important. Aquaporins are water channels that transports water through a process called trafficking. Aquaporin 2 is one of these aquaporins and with a faulty trafficking or mutations it could lead to nephrogenic diabetes insipidus and severe dehydration. Ezrin is a protein in the body which FERM
