Machine learning and artificial neural networks can be used to classify or detect specific sound events in audio signals. Gunshot detection is one use case for such networks and can be used to help law enforcement by alerting officers or triggering camera recordings. However, artificial neural networks with a high performance usually require large amounts of computational power, meaning that they
Problem description: At Scania in Oskarshamn, there is a phenomenon referred to as external picking. External picking is in the context of this report defined as the process where stock-keeping units, not intended for the main production lines, are picked at one of Scania’s Oskarshamn facilities. These items are intended for various organizations within Scania, but also external business partners.
Mosasaurierna utgör en grupp storvuxna ödlor som dominerade positionen som toppredatorer i haven under sen krittid. Det anses allmänt att dessa marina reptiler, tillsammans med de sista landlevande dinosaurierna, dog ut under det massutdöende som markerar övergången mellan krita och paleogen. Nyligen påträffades en del av ett skalltak tillhörande en mosasaurie i ett löst kalk- och flintblock på enMosasaurs are a group of marine reptiles that are considered to have been the apex predators of the oceans during the Late Cretaceous. It is generally assumed that they, along with the last non-avian dinosaurs, died out during the mass extinction that marks the end of the Cretaceous. Recently, a mosasaur skull roof was discovered in a loose boulder on a beach in the vicinity of the town of Hanstho
Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. This thesis aimed to build subject-specific computer models of the hip joint to fi
A hyperspectral image may be decomposed into component spectra and their distri- bution in the image to simplify analysis by revealing underlying patterns and reducing the dimensionality of the image; this may be achieved by the algorithm MCR-ALS. However, the algorithm is time consuming, but could be accelerated by a data re- duction. Data reduction can be done by using a clustering method. In th
The Venezuelan equine encephalitis virus (VEEV) is a highly infectious alphavirus responsible for severe outbreaks and epidemics in the Americas. The nonstructural protein 2 (nsP2) cysteine protease plays a fundamental role in the VEEV replication process, and is therefore, an attractive drug target for structure-based drug design using x-ray crystallography. Generating protein crystals of suffi
Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. This project investigates how the initial condition of a star cluster affects the velo
Culture is in danger. Globalization provides an extraordinary opportunity for people from different countries and areas communicate with each other, which leads to culture intersection. Different kinds of culture are dying with the impact, remaining pity. Within those culture fading away, one of Chinese street food culture called ‘sugar painting’ or ‘sugar man’ attracts me the most. It was popular

This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. The second was to use Deep Learning for semantic segmentation of point clouds and t
Satellite galaxies on bound orbits around the Milky Way (MW) are constantly subject to tidal forces from the MW. If the tidal forces are large enough, they may strip the outermost stars of the satellite, that in turn distribute themselves in long elongated stellar streams. These stellar streams are good probes of the Galactic potential due to the constraints they place on the structure of the pote
Menstrual hygiene management (MHM) is essential for those who menstruate because they have different needs during disasters and crises. Current MHM is focused on immediate needs instead of longer-term vulnerabilities and capacities. The purpose of this thesis is to examine how gendered vulnerabilities and capacities are considered in MHM policies and practice. The aim is to bring more focus to the
The main purpose of this thesis is to prove the Bieberbach inequality using Grönwall’s area theorem, and discuss some consequences of the Montel’s theorem and Carathéodroty convergence theorem regarding single-slit maps, which is essential to the proof of de Branges’ theorem.
The recent spread of COVID-19 pandemic encouraged organisations to facilitate a remote work environment for their employees. This work environment would most likely continue in the upcoming years. At the same time, this context has been followed with an increase in cyberthreats that could affect the optimal processes of organisations. Because of this, cybersecurity awareness must be cultivated to
Sepsis-induced Acute Kidney Injury (AKI) is a common cause of death for sepsis patients, yet it is poorly understood by the medical community. Using Tandem Mass Spectrometry (MS/MS), the blood plasma of 135 sepsis patients has been analyzed to measure protein levels. In this thesis we will present an exploratory application of machine learning on this data, with the intent of producing a model wh
This study examines the relationship between environmental, social and governance performance and corporate credit risk, adding to the literature which investigates ESG in the context of risk management. Using a novel proprietary ESG methodology by Danske Bank Asset Management and credit default swaps as a measure for credit risk, a combination of pooled OLS and panel fixed-effects approach is app
Methodology: The study is conducted as a qualitative research, where empirical data has been collected through semi-structured interviews with Swedish new ventures. The study does further take an abductive approach in terms of the theoretical viewpoint and research perspective. Theoretical perspective: The study is based on previous research about the early phases of new ventures, the importance
Smart grids are often advertised as more environmentally sustainable compared to their “conventional” counterparts. What is highlighted then is their potential to save energy and integrate more renewables into the grid, thus decreasing CO2-emissions. This thesis investigates two less discussed aspects of smart grids, those of circular economy and social sustainability. An initial literature review
