In this study, we demonstrate a successful application of laser absorption spectroscopy in an in-situ optical diagnostic system to map the radial distribution of the number density of vapor-phase aluminum (Al) atoms around a burning micron-sized Al droplet. This technique overcomes the challenges associated with the short optical path (at micron scale) and offers high sensitivity to Al atom concen

BACKGROUND: In this study, we combine proteomics with functional parameters and imaging to examine potential biomarkers that may identify patients at risk of developing persistent lung sequelae following coronavirus disease 2019 (COVID-19).METHODS: We performed multiplex profiling of serum and collected clinical data from intensive care unit (ICU)-treated patients with COVID-19 (n=43) at 4 and 10

Forskningsfråga: Hur påverkar en akademisk ekonomiutbildning, jämfört med enbart en gymnasieexamen, svenska småföretagsgrundares entreprenöriella förmågor? Syfte: Studien syftar till att undersöka hur utbildningsbakgrund påverkar svenska småföretagsgrundares entreprenöriella förmågor. Fokus ligger på att jämföra grundare med en akademisk ekonomiutbildning med dem som endast har gymnasieutbildningResearch question: How does having an academic business degree compared to only a high school diploma shape Swedish small business founders’ entrepreneurial capabilities? Purpose: To examine how small business founders’ educational background influences their entrepreneurial capabilities in the Swedish context, specifically comparing those with an academic business degree to those with only a hig

Startups in the foodtech sector, particularly those working with fermentation-based technologies, face substantial challenges in scaling their innovations. These challenges, commonly known as the Valley of Death, include lack of access to specialized infrastructure, regulatory complexity, and limited knowledge-sharing mechanisms. While Public-Private Partnerships are frequently proposed as instrum

Ordinära differentialekvationer används ofta inom naturvetenskapliga ämnen för att modellera fysiska fenomen. Lösningarna till dessa ekvationer är deterministiska i den mening att vi alltid vet var ett system kommer hamna i framtiden givet ett startvillkor. I denna uppsats studerar vi teorin bakom så kallade stokastiska differentialekvationer (SDE), vilka uppstår genom att lägga till slumpmässigt In this master's thesis we study stochastic integration in three parts --- through continuous semimartingales, Föllmer's deterministic $p$-variational Ito calculus, and rough path theory --- to answer the question whether stochastic integrals can be formulated as pathwise limits instead of limits in probability. The first part covers everything from discrete martingales to stochastic diffe

European Spallation Source (ESS) är en partikelaccelerator under konstruktion i Lund. Den kommer att skjuta protoner mot ett stort “hjul” av Wolfram, för att skapa neutroner till forskning. Hjulet kommer efter användning att bli mycket radioaktivt. En olycka, såsom att kylningssystemet går sönder, skulle släppa ut radioaktivt material som kan spridas med vinden och potentiellt bli en hälsorisk förA gamma-charged particle coincidence spectroscopy setup was constructed, with the intended purpose of analysing future aerosol samples from the ESS. The setup consists of a Compex composite high purity germanium (HPGe) detector, with a bismuth-germanate oxide (BGO) anti-Compton shield (ACS), and a single-sided silicon strip detector (SSD). A 207Bi sample was used to evaluate the performance of the

An experimental campaign took place at the Argonne National Laboratory (ANL) in the summer of 2020. Its goal was to study the exotic modes of decay of neutron-deficient nuclei located near 56Ni. For this thesis, the part of interest from the campaign is the experiment studying the fusion-evaporation reaction resulting from the collision of high-energy nuclei of 36Ar and a 24Mg target, creating exc

An optical system for digital light processing car headlamps was designed and optimized in this project. The specifications include five lens elements and a field of view of 15 degrees horizontally and 7.5 degrees vertically. The system consists of an illumination module and a projection lens assembly. A high-brightness LED source and a rectangular light integrator ensure uniform illumination on t

Nondestructive assaying (NDA) is an important step in ensuring the safe handling of spent nuclear fuel and radioactive waste. The assaying techniques require the use of ionizing radiation detectors to determine the activity of said fuel. One candidate detector for such use is the cerium-activated LaBr3 inorganic crystal scintillator. This scintillator offers excellent resolution, decay times and l

The study shows that while auditors rely on their financial audit expertise, the CSRD introduces new complexities requiring interdisciplinary knowledge and enhanced social support structures. Despite the high level of detail and comprehensiveness in the CSRD provisions, applying the directive in practice demands auditors to engage in subjective interpretive work at both the client and regulatory l

Den så kallade Standardmodellen är allmänt betraktad som den mest framgångsrika fysikaliska teorin. Den förklarar de allra minsta partiklarna i vårt universum med enorm precision. Tyvärr är den ofullständig. Den förklarar inte vad mörk energi eller mörk materia är. Den förklarar inte varför det finns mer materia än antimateria. Den förklarar inte ens vad gravitation är. Trots alla dessa problem haThe standard model can be tested by measuring the electric dipole moment of the neutron. The standard model predicts |d_n| ~ 10^{-32} ecm while experimental searches have reached a sensitivity of |d_n| < 1.8*10^{-26} ecm. Discovery of a nEDM magnitude above |d_n| ~ 10^{-32} ecm would indicate a CP-violation from beyond the standard model physics. An experiment using a novel technique to combine t

This thesis explores a hybrid procedural animation framework that combines physics-based constraints with artistically tunable parameters to generate diverse, real-time character locomotion. Addressing the limitations of traditional keyframing and opaque data-driven methods, the system employs a hierarchical parameter set-ranging from high-level style descriptors (e.g., "energy level") t

Many optimization models from practical problems are too bad to be worked by standard optimization techniques. Here the bad properties include nonconvexity and high discontinuity, such as the problem named low-rank recovery. The traditional approach, nuclear norm minimization, can solve the low-rank recovery but may contain bias. Algorithms like the FBS and the ADMM are highly effective in convex

Givet ett harmoniskt vektorfält u på en begränsad domän kallar vi den mängd där u träder in i domänen för inträdesrand och den mängd där u lämnar domänen utträdesrand. I den första delen av detta examensarbete ställer vi frågan om det är möjligt att ha inre stagnationspunkter och sammanhängande inträdes- och utträdesrand. Svaret i två dimensioner är ‘nej’ för en domän som är homeomorf till skivan.Given a harmonic vector field u on a bounded domain we call the set on which u enters the domain entrant boundary and the set on which u exits the domain emergent boundary. In the first part of this thesis we ask the question of whether it is possible to have interior stagnation points and connected entrant and emergent boundaries. The answer in two dimensions for a domain homeomorphic to a disc i

Denna uppsats syftar till att analysera hur Kunming-Montreal-ramverkets diskurser konstruerar och reglerar antaganden om transformativ förändring, specifikt ontologisk mångfald, i skyddet av den biologiska mångfalden. Vidare studeras hur dessa diskurser har formats, och formas av, rådande nyliberalism i miljöpolitik. Biologisk mångfald spelar en avgörande roll för exempelvis vår livsmedels- och va

In the rapidly evolving landscape of entrepreneurship, Artificial Intelligence (AI) has emerged as a pivotal tool reshaping how founders navigate uncertainty and allocate resources. Grounded in Sarasvathy’s dual logics of causation (predictive, goal-oriented planning) and effectuation (adaptive, resource-driven experimentation), this study investigates whether AI reinforces entrepreneurs’ default

This study examines the effect the ADHD traits hyperactivity/impulsivity and inattentiveness have on entrepreneurs during the planning of the pre-launch phase. Using Person-Environment Fit theory, Dual Pathway Model, and Coping-Dueling-Fit theory, this study explores how cognitive and emotional difficulties associated with ADHD impact entrepreneurial planning. The data was collected through a qual
