Denna uppsats syftar till att stärka förståelsen för dynamisk prissättning och dess möjligheter genom att undersöka effekterna på samhällsnyttan om dynamisk prissättning används inom kollektivtrafiken. Kollektivtrafiken har en stor påverkan på samhällsnyttan och är ett verktyg som kan bidra till att minska social exkludering. Det är därför av stor betydelse att utbudssidan av kollektivtrafiken max

This study evaluated the potential effects of the free trade agreement between the EU and South Korea using a dynamic difference-in-difference gravity regression. The analysis covers the period from 2000 to 2019. The results indicate that the effects were initially weak but gradually increased over time, based on the chosen reference year.

The aim of this thesis is to study whether high retail ownership of a firm impacts the market response to an earnings announcement. To this end, I utilize the traditional event-study methodology in combination with cross-sectional regression. The latter is used to examine whether a company’s ownership structure affects abnormal returns. Two event windows were analyzed, a three-day window and an el

Denna avhandling föreställer sig en ny typ av typologi i staden, en som är sådd och odlad av och för de äldre och de unga. Ett mötesrum som främjar generationsöverskridande relationer och samarbete, samtidigt som det minskar ensamhet och främjar stimulerande miljöer för social utveckling. Genom att omvandla en oanvänd parkering i centrala Stockholm till ett gemensamt utrymme som är delvis trädgårdThis thesis imagines a new type of typology in the city, one that is seeded and cultivated by and for the elderly and the young. A meeting space that fosters intergenerational connections and collaboration while reducing loneliness and promoting stimulating environments for social development. By transforming an unused parking lot in central Stockholm into a shared space that is part garden, part

The combustion of conventional Jet A, alongside two alternative jet fuels, C1 and C5, is simulated with Large Eddy Simulations (LES) in a generic single-cup spray combustor during idle and cruise conditions. The spray is modeled using Lagrangian particle tracking and the combustion chemistry of each fuel is modeled by skeletal reaction mechanisms. The volatility and atomizability of each fuel dire

This work presents a framework for designing self-locking 3D compliant structures using elasto-plastic topology optimization. Design updates are generated using the gradient-based method of moving asymptotes, while the material behavior is modeled under small strain elasto-plasticity. To accurately capture the Bauschinger effect that occur during reversed loading, kinematic hardening is a crucial

Halscancer är en livsförändrande diagnos som innefattar omständliga och obehagliga undersökningar. Då cancern påverkar stämband och form på strupen uppstår frågan: Kan man höra cancer? Detta arbete undersöker hur denna röstförändring kan användas för att tidigt diagnostisera cancer genom att analysera rösten genom ljudbehandling och statistiska modeller för klassificering. För att undersöka huruvThis thesis explores whether throat cancer can be detected from voice recordings using statistical methods in the context of mobile health applications. It focuses on two main questions: Can throat cancer be detected from voice recordings? and Which data features and models perform best in this task? To investigate these questions, acoustic features were extracted from patient recordings and analy

A major inefficiency in contemporary agriculture arises from food-feed competition, where limited agricultural resources are used to produce animal feed instead of human-edible crops. Due to factors like metabolic losses and waste, this is often less resource efficient. This thesis investigates the optimal number of cattle in the Swedish agricultural system when aiming to maximise protein producti

The objective of this study was to assess the feasibility of using a poly(vinylidene fluoride) (PVDF) membrane modified with cellulose/nanostructures as a separation technique for the removal of poly(vinyl alcohol)(PVA)/reactive dyes from synthetic textile wastewater. The goal was to recycle PVA/reactive dye yellow 145 for reuse in the industry while simultaneously reclaiming water for reuse. To a

Experiments using the surface force apparatus have found anomalously long-range interactions between charged surfaces in concentrated salt solutions. Ion clustering has been suggested as a possible origin of this behavior. In this work, we demonstrate that if such stable clusters indeed form, they are able to induce remarkably strong free energy barriers under conditions where a corresponding solu

Roughness is a perceptual characteristic of sound that was first applied to musical consonance and dissonance, but it is increasingly recognized as a central aspect of voice quality in human and animal communication. It may be particularly important for asserting social dominance or attracting attention in urgent signals such as screams. To ensure that the results of roughness research are valid a

Structural biology offers a window into the functionality of molecular machines in health and disease. A fundamental challenge lies in capturing both the high-resolution structural details and dynamic changes that are essential for function. The high-resolution methods of X-ray crystallography and electron cryo-microscopy (cryo-EM) are mainly used to study ensembles of static conformations but can

This chapter explains how a mutual fund culture, which strengthened the link between households and the stock market, emerged exceptionally early in Sweden. We explore the popularisation of individual shareholding through state-subsidised fund savings schemes, the Tax Funds (introduced by the centre-right government in 1978) and the similar Everyman’s Funds (introduced by the Social Democratic gov

Droughts present a significant global challenge, particularly to forest ecosystems in regions such as eastern New South Wales, Australia, which is known for its dry climate and frequent, intense droughts. Recent studies have indicated a notable increase in tree mortality and canopy browning across this area, especially during the recent extreme drought period culminating in the Black Summer of 201

In this chapter, we evaluate how the concept of the entrepreneurial ecosystem - a systemic approach to regional economic development that is receiving increased attention from both policymakers and academics - can assist in analysing and understanding the informal economy. We argue that despite the focus of entrepreneurial ecosystems on high-growth entrepreneurship, the ‘systemic’ perspective of t

Against the backdrop of the current geopolitical situation, logistics preparedness emerges as a pivotal area of focus for defence supply chains. Despite the critical role of commercial suppliers, research on utilising these in defence logistics and supply chains remains scarce. Adopting a supply chain governance lens, we have conducted a systematic literature review to provide an overview of exist
