This thesis explores the potential of integrating predicted founder personalities, based on the Big 5 Personality Framework, into Machine Learning (ML) models to enhance the accuracy of early-stage startup success predictions. Leveraging Natural Language Processing (NLP) techniques, we extracted personality insights from founders' tweets, focusing on US startups funded between 2013 and 2015. O
Background: Alleviating poverty is critical for achieving sustainability (Zomorrodi et al., 2019). One business approach to alleviate poverty is the Bottom of the pyramid (BoP) approach which implies engaging the poor in doing business, and including them into supply chains with both profitability and poverty alleviation as objectives (Brix-Asala et al., 2021). The populations living in the BoP ar
This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car. For that, aerodynamic validation is
Nature-based solutions (NBS) can provide a range of benefits to tackle acute sustainability challenges in an enduring and cost-effective manner. Increasing recognition of the value of these solutions has led to their adoption across the globe. However, a majority of NBS projects are implemented with public funding, though the participation of the private sector is vital to achieve comprehensive op
The purpose of this study is to examine how housing quality has changed over a span of 50 years. The aim is also to investigate how sustainable development has evolved during the same period, with the intention of drawing conclusions regarding the changes in sustainable development within the construction sector. A quantitative method has been employed, involving the collection of numerical data a
Streamflow analysis helps us understand the availability of water resources in a region or a river. Accurate and timely streamflow monitoring is essential to improve our understanding of the hydrological cycle. Streamflow information is also necessary for many applications, such as irrigation planning, watershed management, hydropower products, flood control, and integrated water resources managem
The development of digital technology affects our whole society, and the cultural heritage sector is no exception. The aim of this thesis is therefore to map practical experiences of digitization and cataloguing of older material at Lund University, both from a library perspective and a research perspective. To achieve the purpose of the study, qualitative interviews have been conducted with libra
The exact workings of amelogenin (AMG) as a key-regulator in the formation of enamel is still to be determined. It has been observed however, that AMG promotes tissue-regrowth and has promotive effect on e.g., osteoblastic cells and could therefore be of interest for medical applications. This project aimed to utilize AMG’s self-assembly properties to fabricate a protein-based biomaterial for cult
Denna masteruppsats undersöker den snabbt växande europeiska marknaden för laddning av elbilar, med fokus på integrationen av batterienergilagringssystem vid laddningsstationer, särskilt för snabbladdning med likström. Genom intervjuer med branschintressenter och experter, samt en omfattande litteraturgenomgång, identifierar studien en eskalerande efterfrågan på batterisystemlösningar. Denna efterThe surge in electric vehicle (EV) popularity is reshaping the automotive landscape, steering us towards a greener energy future. However, this transformation is not without its hurdles. A significant challenge lies in developing efficient EV charging infrastructure. Faced with limited grid capacity and extended lead times for grid connections, the rapid expansion of this infrastructure demands in
Hypertyreos är en sköldkörtelsjukdom där sköldkörteln är överaktiv och producerar för mycket hormoner. Tillståndet kan orsaka symptom som är jobbiga att leva med i vardagen, till exempel hjärtklappning, svettningar, yrsel och illamående. En utav de behandlingar som används mot hypertyreos är radiojodbehandling. Vid radiojodbehandling utnyttjar man sköldkörtelns egenskap att absorbera jod från den Aim: The aim was to estimate the uncertainty of various factors, influencing the radioiodine uptake (RAIU) at clinical measurements of hyperthyroid patients. Furthermore, to evaluate the estimation of thyroid volume from nuclear medicine scintigraphic images. Another aim was to investigate in what extent these uncertainties may influence the eventual therapeutic radioiodine activity, and thereby t
Varje år diagnostiseras ungefär 1600 personer i Sverige med huvud- och halscancer. De flesta av dessa patienter behandlas med strålbehandling, men tyvärr är prognosen för många ganska dålig. Forskning pågår för att förbättra behandlingen och utveckla mer effektiva sätt att döda tumören, samtidigt som man strävar efter att minimera biverkningarna. Ett sätt att göra detta är att använda avancerade bDiffusion magnetic resonance imaging (dMRI) in radiotherapy has the potential to facilitate the identification of treatment resistant regions within tumours, such as areas with insufficient oxygen supply. This is particularly interesting in head and neck (H&N) tumours with poor prognosis correlated with unidentified hypoxic areas. However, dMRI is sensitivive to the magnetic susceptibility dif
Alzheimers sjukdom är idag den vanligaste neurodegenerativa sjukdomen i världen. Det klassas som en ålderssjukdom, och med en ökande medelålder i befolkningen, ökar således risken för fler att drabbas. Sjuk- domen orsakar en förtunning av hjärnvävnad och presenterar sig med symptom så som minnesstörningar som gradvis blir värre. Symptomen av Alzheimers sjukdom kan däremot uppkomma så sent som flerIntroduction and aim The changes in the brain caused by Alzheimer’s disease usually begin many years before the first symptoms arise. The effect of the neurodegenerative disease involves both morphological and microstructural changes in the brain, due to neurons dying. These changes in the microstructure can be measured with diffusion MRI. The resolution however limits the accuracy of the imaging,
Magnetresonanstomografi, eller MRI, är en central och växande del av dagens vård, vilket ger läkare en bred verktygslåda för att diagnostisera en mängd olika medicinska tillstånd. En typ av undersökning som går att utföras med en magnetkamera är diffusionsundersökningar, som speglar partiklars slumpmässiga rörelse i vatten. Denna typ av undersökning möjliggör kartläggning av organ baserat på vävnaMagnetic Resonance Imaging (MRI) is a powerful tool for diagnostics in medical imaging, where diffusion-weighted (DW) MRI is a modality used for probing tissue microstructure and function at a molecular level. Due to poor signal-to-noise ratio (SNR) and spatial resolution in DW-MRI, the noise floor typically induces a large signal bias by elevating the signal intensity. This bias affects the accur
Social collaboration tools, such as Slack and Microsoft Teams, are highly appreciated in the modern workplace due to their enabling of efficient communication and collaboration. Research highlight that the tools are making communication more visible, which is said to increase collaboration, productivity, and knowledge-sharing between organizational members. This thesis problematizes the lack of pr
När våld mot ett barn rapporteras till myndigheter är det av yttersta vikt att allvaret kan kommuniceras effektivt och bedömas korrekt. Denna studie genomfördes i två faser och syftade till att undersöka perceptuella skillnader i kalibrering och noggrannhet för fysiskt och psykologiskt våld mot barn. I fas 1 samlades förstahandsberättelser in från föräldrar (narratörer) som bevittnat våld mot sinaWhen violence against a child is reported to authorities it is of utmost importance that the severity can be communicated efficiently and evaluated correctly. This study was conducted in two phases and aimed to investigate perceptual differences in calibration and accuracy for psychological and physical violence against children. In phase 1 first-person narratives from parents (narrators) who have
Socio-environmental crisis are also crisis of imagination. In the city of Taranto, the heavy industry has had devastating socio-environmental effects, and the dominant narrative still considers environmental and social sustainability as a double bind. Consequently, to this date there is no sign that anticipate a solution to the socio-environmental crisis. By means of 3 horizons framework, this wor
