This study examines whether the canonical stochastic volatility (SV) model outperforms the standard GARCH(1,1) model across different market regimes, and whether relatively simple hybrid LSTM extensions improve forecasting accuracy. Using daily data from the Dow Jones, S&P 500, and FTSE 100 indices, volatility forecasts are evaluated on the stressed exogenous COVID-19 crisis, as well as a calm
This thesis examines how consolation is expressed in the Finnish devotional writings of field chaplain Carolus Olai Pictorius during the Swedish campaign in Livonia in 1622. These texts were written for Finnish soldiers in the Swedish army, many of whom remained in Riga as part of the garrison after the city's capture. The study aims to analyse how language, theology, and pastoral care relate
Urban areas are increasingly exposed to extreme precipitation events, which can disrupt critical infrastructure and damage the built environment. While flood impacts are often assessed separately for buildings or road networks, this study analyses both flood-induced road inaccessibility and building flood risk in Gothenburg using a climate-adjusted 100-year rainfall at both the city scale and the
Fragility fractures are a major health concern and accurate estimation of bone strength is important for fracture risk assessment. Finite element (FE) models can provide reliable estimates of femoral bone strength, but traditional approaches typically require three-dimensional imaging and computationally intensive model generation. Previous research has enabled reconstruction of subject-specific F
Sprickor i asfaltsbeläggningar är en av de tidigare indikatorerna på strukturell nedbrytning och har betydelse för planering av vägunderhåll och trafiksäkerhet. Traditionella okulära inspektioner är resurskrävande och påverkas av subjektiva bedömningar samt yttre faktorer som ljus och väder. För att öka objektiviteten kan tekniska mätsystem såsom Laser Crack Measurement System (LCMS) användas vilk
Flood risk is influenced not only by climate change but also underlying factors including unplanned urbanization, environmental degradation, poverty, social inequalities and weak governance. Given its complexity, effective flood risk management requires a better understanding of its conceptual context and comprehensive assessments that beyond hazard consider exposure, vulnerability and capacity. T
Studien undersöker den möjliga världen som Carl Jonas Love Almqvists "Skaldens natt" utgör. Utgångspunkten för studien är de specifika textuella villkoren som "Skaldens natt" är konstruerad utifrån. Undersökningen ämnar att begripliggöra "Skaldens natt". Både alstrets inre egenskaperna som fiktion och konstruktion samt hur den fiktiva världen förhåller sig till genr
In the hardware development space, field programmable gate arrays (FPGAs) are in a unique position as a result of their in-field re-programmability. In contrast to the traditional design process of integrated circuits, FPGAs allow iterative de- velopment workflows closely resembling software development’s sprint-based pro- totyping. For this to work, efficient workflows for verification are key. V
Trygghet i offentliga trafikmiljöer är en central aspekt av hållbar och inkluderande stadsplanering. Studien undersöker hur kvinnor och män upplever trygghet vid Helsingborg C, en plats som kännetecknas av hög genomströmning av människor, varierande ljusförhållanden och återkommande upplevelser av otrygghet. Syftet är att öka förståelsen för hur kön, tid på dygnet och miljömässiga faktorer samverkThis bachelor’s thesis explores how safety is experienced at Helsingborg Central Station (Helsingborg C) from a gender perspective. The aim is to analyse how women and men perceive safety in and around the station area and how these perceptions are influenced by both physical and social environmental factors. The study also seeks to identify which elements contribute most strongly to feelings of i
This study applies a cost-benefit analysis methodology to evaluate the socio-economic profitability of emergency phones and portable fire extinguishers for fires in Swedish road tunnels. The benefits of each component were determined through a qualitative assessment of emergency phones and a quantitative analysis of portable fire extinguishers. The findings indicate that emergency telephones are l
In microfluidic systems, resonant acoustic fields enable controlled particle manipulation, a phenomena known as acoustophoresis. These contactless and low-cost processes have successfully been applied to manipulate bulk particle populations, however robust single-cell manipulation for single-cell analysis remains a challenge. This work presents an experimental investigation into optimising the con
Arctic permafrost plays an important role in global carbon storage and has been thawing due to rising temperatures imparted by climate change. Monitoring the active layer thickness (ALT), the seasonally thawing and refreezing uppermost permafrost layer, is essential for understanding permafrost dynamics and their response to warming temperatures. Traditional ALT monitoring relies on ground-based m
This thesis, along with the Propagation Predictor written in MATLAB, offers a quick and easy way of predicting how Electromagnetic (EM)-waves will propagate given the current atmospheric situation. While the thesis is written with the goal of explaining choice and phenomena, the Propagation Predictor is built with the goal of not requiring deep knowledge of neither EM-waves nor meteorology. Meteor
Denna uppsats undersöker den politiska teaterns roll och potential att skapa verklig samhällsförändring. Utifrån ett materialistisk perspektiv ställs frågan huruvida teatern, som primärt verkar i åskådarens medvetande, är begränsad till att enbart förändra tankesätt eller om den även kan vara ett direkt medel för konkret politisk och materiell förändring. Syftet är att kartlägga vår tids svårighet
This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h
Parasites play a fundamental role in explaining variation in population dynamics in wild ecosystems while also acting as a better model-system to study similar or related human infections. Since the late 1800s, malaria parasites have played a crucial role in vector-borne disease research. Many intrinsic and environmental factors can affect the level of infection transmission and prevalence among a
Large and old trees provide important habitat structures and support a high diversity of species. Habitat continuity and landscape connectivity is crucial for species associated with oaks. Fragmentation, agriculture intensification and changed forest management has caused a reduction of old and large oaks, which threatens the long-term persistence of oak associated species by reducing habitat cont
As the market for biopharmaceuticals grows, the demand for continuous downstream pro-cessing (DSP) increases. This thesis tackled one of the key factors in successfully creating a continuous chromatography process: the ability to have an automated supply of complex buffer solutions. It aimed to develop and evaluate a Buffer Preparation Unit using an ÄKTA Pure machine, as well as the development of
This study investigates the occurrence and distribution of 18 lichen species associated with Nordic alvar and Precambrian limestone habitats on Gotland and Öland, which represent globally unique environments with a generally high biodiversity. During field surveys in the spring of 2025, historically known sites of the chosen lichen species were revisited, where species presence, frequency, and env
