In this thesis I study the performances of artificial neural networks (ANNs) and three various ARCH-type models to predict weekly volatility of the Swedish (OMXS30), the British (FTSE100) and the Australian (S&P/ASX200) major stock indices. The three various ARCH-type models are the GARCH(1,1), the EGARCH(1,1) and the TGARCH(1,1). The purpose is to investigate if ANNs outperform the more tradi

During the last three years the Malmö City Library made a transition from the Swedish classification system SAB to the internationally established Dewey Decimal Classification. The Malmö City Library is the first public library of a larger magnitude to make such a transition in Sweden. The aim of this thesis is to contribute with knowledge and reflections about how the Dewey Decimal Classification

Malaria är en sjukdom som överförs av myggor; det har överförts påverka mänskligheten i mer än 10 000 år, det påverkar mellan 700 000 och 2,7 miljoner människor per år och det kan vara dödligt, därför finns det ett stort och ökat intresse för att utveckla en bot mot den. Quinin, den första antimalarialen, isolerades från chinchona-trädet år 1632. Denna förening användes i stor utsträckning i formMalaria is a disease that is transmitted by mosquitoes; it has been transmitedaffecting humanity for more than 10.000 years, it affects between 700 000 and 2.7million people per year and it can be deadly, therefore there is a large and increasinginterest in developing a cure against it. Quinine, the first antimalarial, was isolated from the chinchona tree in 1632. Thiscompound was widely used in

I dagens samhälle har vi en ofantligt hög konsumtion av förpackade drycker. För att ständigt förbättra kvalitén och korta ner produktionstid krävs en ständig utveckling av produkter. I applikationer för öppningsbarhet och skruvkorkar till förpackningar används bland annat plasten polypropen. Målet med studien som har gjorts har varit att undersöka hur plasten varierar i vissa utvalda egenskaper soThis master thesis is the result of cooperation between Lund University and Tetra Pak, performed by a student at Engineering Nanoscience, LTH. The aim is to explain how different molecular weights and molecular weight distribution of isotactic homo-polypropylene affect resulting properties. Examined properties are mechanical properties by tensile testing and tensile impact, shear viscosity by capi

Säker hantering av animaliska biprodukter minskar spridning av sjukdomar Ungefär 200 människor har dött på grund av Creutzfeldt-Jakobs sjukdom, efter att ha ätit kött från sjuka kor. Sjukdomen är förknippad med den ”galna ko-sjukan” även kallat Bovin Spongiform Encefalopat (BSE). BSE sprider sig genom att kött- och benmjöl framställt av BSE-sjuka nötkreatur har använts som foder. BSE sprids till Animal by-products (ABP) is an unknown area in food control in Sweden, mainly grocery stores. ABP affects many different areas, such as food, feed, animal welfare and waste. Swedish Board of Agriculture defines animal by-products as follows: "Animal by-products are material from the animal kingdom which is not food and have not yet been processed or treated to be included in the concept of m

This thesis examines EU’s adoption of a human security approach and the extent to which it has been part of crisis management discourse as well as practice in the Sahel region of Africa. It tells the story of a maturing process for a core approach in EU security policy; that is, the story of human security and how the concept has evolved from a state of innocence to gradual experience and adolesc

High quality III-V semiconductors on silicon substrate can make for significant progress in gate electrostatics and optoelectronic devices. Indium antimonide with its inviting properties can play a key role to further facilitate devise integration. But the question is, is it possible to obtain high quality III-V semiconductors on low cost silicon and still be able to manufacture it at large scale?

This thesis is a study of the moral, medical, and socioeconomic arguments in favor of a racial hygienic sterilization legislation carried out in conservative, social democratic and socialist newspapers in Denmark from 1911-1923. While the sterilization legislation did not come into effect until 1933, the question was heavily discussed publicly in the preceding years. The public belief in omniscien

I samband med påföljdsreformen år 1989 infördes preciserade regler för påföljdsval och straffmätning i det svenska straffrättssystemet, med syftet att öka förutsägbarheten och möjliggöra en enhetlig rättstillämpning. Bland annat infördes billighetsskälen, ett antal skäl hänförliga gärningspersonen, dennes agerande eller sådant som inträffat efter begånget brott. I det fall omständigheten är av särIn connection with the Swedish penal reform of 1989, specific rules for sentencing and penalty assessment were introduced into the Swedish criminal justice system, with the aim of increasing predictability and enabling uniform application of the law. The grounds for equity were established, consisting of various factors related to the offender, his or her actions, or events occurred after the crim

Editionsinstitutet och den processuella editionsplikten möjliggör för en part att med domstolens hjälp, under vissa förutsättningar, avtvinga motpart eller tredje man skriftliga handlingar som kan tänkas äga betydelse som bevis i en pågående tvist. En hel del har skrivits om editionsinstitutet och den processuella editionsplikten. Trots detta är rättsläget i många avseende fortfarande oklart. HögThe procedural duty of disclosure enables a party, with the assistance of the court and under certain conditions, to compel the opposing party or a third party to produce written documents that may be deemed significant as evidence in an ongoing trial. Much has been written about the procedural duty of disclosure. Nevertheless, the legal landscape remains unclear in many respects. In recent years

In recent years, forest fires have become more frequent and severe worldwide. Sweden experienced an extreme fire season in 2018, resulting in extensive burnt areas and challenges in fire suppression. With climate change such extreme fire seasons are likely to become more common, highlighting the urgent need for effective fire risk assessment tools. This study aimed to develop a simplified forest f

With future technologies and Industry 4.0, the need for robust and accurate positioning to optimize productivity and industrial operations increases. The previous positioning methods using triangulation or angle-of-arrival are not good enough, especially not for clutter-dense factories with poor line-of-sight conditions. For this thesis project, a convolutional neural network model was trained t

Adopting a postcolonial theoretical framework, drawing specifically on the concepts of imagined geographies and subaltern nationalism, this thesis explores the motivations behind pro-Palestinian activism among the post-accord generation in Northern Ireland since the escalation of the Israeli-Palestinian conflict beginning on October 7, 2023. Based on in-depth interviews, field observations and onl

Arterial stiffness (AS) and chronic kidney disease (CKD) are common in the older population. AS results in increased pulsatile pressure, elevated pulse pressure (PP), and is linked to hypertension. PP is a surrogate for AS. The kidney has low vascular resistance mechanisms, presumably making it vulnerable to the increased pulsatile pressure and hypertension associated with AS. The aims of this stu

Introduction: Device-aided therapies (DATs) have been developed to provide continuous drug delivery (CDD) to people with advanced Parkinson’s disease (PD) whose symptoms can no longer be effectively managed with oral or transdermal therapy. Intrajejunal infusion of levodopa–carbidopa intestinal gel (LCIG), delivered via the CADD Legacy 1400 pump, is an established CDD option, while levodopa–entaca

A finite-element model is presented for numerical simulation in three dimensions of acoustophoresis of suspended microparticles in a microchannel embedded in a polymer chip and driven by an attached piezoelectric transducer at MHz frequencies. In accordance with the recently introduced principle of whole-system ultrasound resonances, an optimal resonance mode is identified that is related to an ac

This report describes the thermal behaviour of nanotitania precursors and the influence of various amines and peroxide treatment on properties of TiO2. Thermal degradation of amine-containing amorphous (peroxo)titanates was examined via TG–DTA coupled with evolved gas analysis (EGA) by mass spectrometry in inert and oxidizing atmosphere. Crystallization to anatase and subsequent transformation to

Adipocyte-rich omentum offers “good soil” for disseminating ovarian cancer (OvCa), contributing to therapeutic difficulty. However, little is understood about the association between adipocytes and tumor growth at peritoneal dissemination site. Herein, we report the induction of adipocyte dedifferentiation by OvCa cells and pro-tumorigenic effects of resulted adipocyte-derived fibroblasts. We conf
