The standard approach for visual place recognition is to use global image descriptors to retrieve the most similar database images for a given query image. The results can then be further improved with re-ranking methods that re-order the top scoring images. However, existing methods focus on re-ranking based on the same image descriptors that were used for the initial retrieval, which we argue pr
Ethylcellulose thickened oil (EC oleogels) has a significant retarding effect on lipolysis and may be used for controlled-release formulations. However, the high temperature (above 150 °C) used during the gel-forming process becomes an obvious limitation that hinders the application of EC oleogels to temperature-sensitive active ingredients. A cold-mixing procedure that could allow for an encapsul
Denna avhandling undersöker hur svenska män som betalar för sex ger mening åt sina handlingar och förhåller sig till ett moraliskt sammanhang präglat av kriminalisering, stigma och offentlig fördömelse. Med utgångspunkt i antropologiska perspektiv på moral, stigma och hemlighållande förstås männens berättelser som uttryck för moraliskt arbete: det pågående, situationsbundna arbete genom vilket indThis dissertation examines how Swedish men who pay for sex make sense of their actions and orient themselves within a moral landscape marked by criminalization, stigma, and public condemnation. Drawing on anthropological approaches to morality, stigma, and secrecy, the study conceptualizes the men’s accounts as forms of “moral work”: the ongoing, situated labor through which individuals seek to su
Agri-food systems globally experience growing difficulties associated with losses after harvesting, irregular quality, and inefficient utilization of resources, particularly within fruit supply chain (FSC). Given the complicated structure in FSCs, it is critical to guarantee quality at all levels to sustain customer satisfaction and optimize the utilization of resources. Conventional inspections a
As the impact of climate change intensifies, there is an urge to adapt Swedish residential buildings with a special focus on improving their energy efficiency and resilience. In this study, adaptive strategies through Artificial Intelligence and Reinforcement Learning will be provided for the energy management of different Swedish residential buildings. The aim will be the optimization of energy u
A set of nineteen C-galactopyranosyl ligands, which included constrained compounds based on a bicyclic trans-decalin type system. were synthesized via click chemistry from 2-(β-d-C-galactopyranosyl) ethylene azide intermediates. The compounds were evaluated for binding to various galectins and the most promising inhibitor from the series was a constrained 3-O-benzylated galactopyranose derivative,
INTRODUCTION: Health promotion in everyday settings is of great importance for both individual health and organizational sustainability. A settings-based approach emphasizes how social, physical, and organizational contexts shape the conditions for health. Central principles in health promotion are participation, empowerment, and person-centeredness, which emphasize the active role of the person o
Denna avhandling undersöker styrningen av koldioxidavskiljning och -lagring (CCS) i den nuvarande fasen av policydriven implementering inom europeisk klimatpolitik. Min forskning placeras i mellan etablerad kritik av CCS och dess framväxande, centrala roll i bindande nettonollstrategier. Jag intar en kritiskt pragmatisk hållning som erkänner att CCS är en omtvistad teknik som innebär risker för inThis thesis examines the governance of Carbon Capture and Storage (CCS) technology in its current phase of policy-driven deployment within European climate policy. Positioned in the gap between established critique of CCS and its newly central role in binding net-zero strategies, my research adopts a critical-pragmatic stance to acknowledge that CCS is a contentious technology embodying risks of c
This paper is concerned with a recently proposed scalable protocol for vehicle platooning, known as the serial consensus protocol. This achieves coordination of second-order integrator systems through a series connection of first-order conventional consensus protocols, and has been theoretically shown to have advantageous stability and performance properties. We implement this protocol on a vehicl
In recent years, Predictive Digital Twins (PDT) have emerged as a potential tool to monitor and predict the behavior of dynamic systems, including nature-based solutions in natural coastal systems. Here, we test the potential of using a simple, coupled shoreline and beach-dune model as a base for a PDT. The models exchange sediment flux balance information at each time step and recalculate shoreli
This paper studies cone-preserving linear discrete-time switched systems whose switching is governed by an automaton. For this general system class, we present performance analysis conditions for a broadly usable performance measure. In doing so, we generalize several known results for performance and stability analysis for switched and positive switched systems, providing a unifying perspective.
We propose a method for estimating the 3D position of a target point, given multiple measurements of it, using mm-wave radar data. Given azimuth headings and range estimates from posed radar positions, we find the 3D position, using an approximate, but geometrically and statistically meaningful cost. The 3D position is found in an optimal way, using this approximate cost. By deriving the Lagrangia
Abstract INTRODUCTION Countries have varying, limited healthcare budgets for emerging disease-modifying therapies. Cost-effectiveness analysis, combined with country-level cost-effectiveness thresholds, can be used to estimate value-based prices (VBPs) for lecanemab and donanemab across 174 countries. METHODS The cost-effectiveness of lecanemab and donanemab was estimated using incremental cost an
We perform a validation analysis on the multipolar model of opinion dynamics. A general methodology for using the model on datasets of two correlated variables is proposed and tested using data on the relationship between COVID-19 vaccination rates and political participation in Sweden. The model is shown to successfully capture the opinion segregation demonstrated by the data and spatial correlat
Peptide therapeutics offer advantages in specificity and affinity, yet the potential propensity to self-associate and aggregate poses a challenge for the development of stable oral formulations. This master’s thesis evaluates the utility of the fluorescent dye Thioflavin T as a structural probe to monitor the aggregation of glucagon-like peptide-1 receptor agonists, specifically Liraglutide and Se
This thesis examines how young people in Finland make sense of profit-oriented drug selling and construct drug dealer identities. Drug use and related harms have increased globally in recent years. In Finland, an increase in minors selling drugs for financial profit has been noticed by the police and a non-governmental youth work organization Children of the Station. The aim of this thesis is to e
Archaeology and archaeological sciences are inherently spatial disciplines. Thus, it is of no surprise that GIS (Geographic Information System) has found its way into archaeological practice, providing an environment for data organisation, analysis and visualisation. Over the past few decades, archaeogeophysics has become an integral part of archaeological practice. The results of these studie
Tentamen 2007-03-09 Uppgift 1 En patient har ordinerats strålbehandling med två motstående fält för en metastas i en ryggkota, se figur nedan. I punkt A (som också är isocenter) önskas 30 Gy, uppdelat på 10 fraktioner. För att åstadkomma en homogen dos i target vill man ha så lika vikt som möjligt för de båda fälten. I punkt B, som representerar tarmarna, vill man emellertid inte överstiga 2.5 Gy
