This paper presents a novel approach to dynamic asset allocation using regime-based modeling and a diverse set of features. The objective of this study is to select the most important features that reflect the state of the market, apply an effective method for detecting market regimes using the selected features, and design an effective trading strategy that leverages the identified sequence of ma

CellaVision’s digital hematology systems are designed to analyze blood and pre-classify different types of blood cells. Some abnormal white blood cells are rare, which can cause imbalanced datasets. This can lead to a decrease in pre- classification performance and a need to carry out more time-consuming data gathering. The aim of this thesis is to investigate the possibility of using deep learnin

This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 a

A qualitative research strategy was decided, with semi-structured interviews as the research method. The coding was thematic, and eight different themes of motivators and barriers to co-creation were found. Furthermore, the

Uttrycket av en biomarkör i mantelcellslymfom och dess biologiska betydelse Nästan alla känner någon som har diagnostiserats med cancer. Det är en sjukdom med komplexa och svårbehandlade subtyper, varav mantelcellslymfom är ett exempel. Mantelcellslymfom är en typ av cancer som angriper våra immunceller och drabbar framförallt män över 65 år. Konventionella behandlingsstrategier är ofta generalisMantle cell lymphoma (MCL) is an aggressive B-cell lymphoma with poor response to generalized treatment regimens. Tools for stratifying patients based on molecular profiles of the tumor, such as the expression level of a biomarker, are needed to enable more targeted therapies. A potential biomarker for MCL patient stratification is the surface protein CD25. This study aimed to assess the frequency

This thesis investigated how the short video sharing application Douyin produces an effect on city tourist images’ construction and dissemination in China, taking the Internet-famous city of Xi’an as a case study. Based on the semiotic theory and “5W” communication theory, the author collected 30 Xi’an-related short videos on Douyin as samples and recorded the relevant data manually for analysis.

Smart Tourism följs av många utmaningar där några är att hitta en unison förståelse för begreppet, överkomma den kunskapsbrist som finns inom digitalisering och att veta när digitaliseringen är fördelaktig för såväl besökare som aktör. Möjligheter inom Smart Tourism är att skapa förutsättningar för aktörer att komma i kontakt med besökare och sedan inspirera dem till att boka. En annan möjlighet ä

Spänningsmätningar och laserdiagnostik lär oss om brandsäkerhet i batterier. Som du förmodligen känner till är användningen av fossila bränslen som drivmedel till bilar skadlig för både människor och miljö. Istället är elbilar en lösning som många biltillverkare satsar på idag. Volvo Cars har till exempel beslutat att alla bilar som säljs år 2030 ska vara helt eldrivna. Utvecklingen av elbilsbatDue to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. This work aims to investigate the role of electrical discharge as a proposed ignition source of battery vent gases. A set of research questions for

Andelen äldre vuxna växer stadigt världen över. År 2030 beräknas en av sex personer i världen att vara 60 år eller äldre. Denna demografiska förändring innebär stora utmaningar för många länder. Bland annat att säkerställa att dagens snabbt växande tekniska utveckling tillgodoser behoven hos äldre vuxna. Flygindustrin är en av de industrier där det går att se en ökning av äldre vuxna bland passageThe demographic group of older adults is growing significantly worldwide. It is predicted that by 2030, one in six people in the world will be aged 60 years or older. This demographic shift presents major challenges for many countries to ensure that the fast-growing technology developments are ready to fulfil the needs of older adults. The flight industry is one of the industries that experience a

ChatGPT är det senaste tillskottet inom AI-teknik, en konversationsmodell skapad för att svara på frågor och producera text. Trots att ChatGPT är mycket uppmärksammat och har blivit en allt vanligare del av människors vardag, är tidigare psykologisk forskning kring denna funktion begränsad. Därför ansågs det intressant att fördjupa sig inom detta samhällsaktuella ämne. Studien valde att undersöka ChatGPT is the latest addition in AI technology, a conversational model created to answer questions and produce text. Although ChatGPT is receiving a lot of attention and has become an increasingly common part of people’s everyday life, previous psychological research on this feature is limited. Therefore, it was considered interesting to delve deeper into this socially relevant topic. The study c

Previous research has shown that the relationship between the news and parliament is complex and highly variable. Studies have found that in many countries, parliament has minimal influence on the news. However, in the UK, a reciprocal influence between parliament and the news was found, with the media having a stronger effect. This thesis investigates how the news and parliament affect each other

Behovet av att skapa hållbara och flexibla byggnader har vuxit under de senaste åren, inte minst för att möta högt uppsatta klimatmål. Utrymmena mellan byggnaderna, med andra ord utemiljöer, har regelbundet prioriterats sekundärt och anpassats i stor utsträckning efter det bebyggda behovet. Utemiljöer i urban kontext innehåller ofta mer eller mindre kollektiva varor, som är icke-exkluderbara och iThe need for sustainable and flexible buildings has grown in recent years in order to meet climate goals. However, outdoor environments have often been overlooked and is often strongly controlled by the built environment. These spaces hold significant social and ecological benefits but pose challenges for real estate companies as they lack direct financial returns. Well-designed outdoor environme
