DGEM (Devlabs, Copenhagen) is a small IoT product for air quality management and can be equipped with various integrated low-cost small sensors and hardware interfaces and provides comprehensive data collection capabilities. A one-month field observation test was conducted with reference instruments at Hyltemossa research station from 6th Dec. 2023 to 10th Jan. 2024 to validate this sensor bef
The main goal of this study is to provide insights and knowledge into the matters of queer representation in entertainment media, with a particular focus on the depiction of queerness in association with crime on-screen, from the perspective of the LGBTQIA+ community itself. More specifically, the investigation is grounded on four main theories relating to queer studies, intersectionality, social
The wide adoption of machine learning (ML) models in resource-constrained devices for complex vision tasks is contingent on improved computational efficiency. Quantization is a tool for model compression in which weights and activations are approximated with low-precision datatypes, to achieve a smaller model with reduced latency and memory usage. In this thesis, we seek to apply post-training mix
Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). Recorded test signals with corresponding manually labelled ground truth files are used to determine the accuracies of the method
In the realm of urban planning, urban greening – the creation or restoration of green spaces in cities – has risen as an attractive approach for policy-makers and planners engaged in sustainability. As the benefits of urban greening are many, from social and cultural to environmental and economic, it has become positioned as a win-win solution to several urban challenges related to sustainable dev
In today’s world, many companies are pushed to adapt their business models in response to evolving external pressures. While business model change has received increasing attention in research, relatively little is known about how such change actually unfolds inside organizations. Responding to calls for a more dynamic view of business models, this thesis explores how strategy process factors medi
Humanitarian aid workers (HAWs) face increasing risks in conflict zones, with 2024 marking the deadliest year on record. International humanitarian organisations (IHOs) must address this trend to continue delivering aid and protecting HAWs. This study investigates how IHOs adapt to the evolving risks in these contexts and explores challenges that adaptation measures may entail. A qualitative resea
Thirteen different polymers have been investigated in the tries to find a polymeric water-based binder for the brazing alloy F300. F300 has the chemical formula Fe-24Cr-20Ni-10Cu-7P-5Mn-Si and is a gas-atomized metal powder used for high temperature brazing. Except being water-soluble the polymers used for the binder, would have to provide sufficient viscosity at a maximum 2 wt% and not gel under
There are several aspects of rune stones that can be discussed and analysed. With the help of digital tools, it is possible to look at social dimensions of archaeological objects in ways that were previously difficult to explore. In this thesis, the aim is to analyse rune stones from a spatial perspective by looking at their possible role in the landscape, what type of context they are found in an
This study examines the conditions for climate-friendly innovation in Region Skåne. It focuses on small companies within the CleanTech-sector with a total annual turnover below 10 MSEK. A short literary study was conducted about the innovation system for Swedish CleanTech-companies in general. Reading material from Region Skåne was also examined. Five interviews was carried out with representative
This thesis discusses commemoration processes of the Second World War and the Holocaust in Sweden. The timeframe for this analysis is set from 1995 on when Sweden joined the European Union and general interest in Holocaust research increased in all EU member states in the 1990s. The thesis focuses on memorials and exhibitions in Stockholm dealing with the topic. Through interviews and visual analy
Structural variants (SVs) rearrange large segments of DNA1 and can have profound consequences in evolution and human disease2,3. As national biobanks, disease-association studies, and clinical genetic testing have grown increasingly reliant on genome sequencing, population references such as the Genome Aggregation Database (gnomAD)4 have become integral in the interpretation of single-nucleotide v
Cultural ecosystem services (CES) are nonmaterial benefits that people obtain from ecosystems. The CES subcategories cover a wide range of domains (e.g. recreation, conservation of cultural heritage, human-nature relations). The CES concept has been proposed to acknowledge the nonmaterial values linking people and nature in social-ecological systems. Agricultural landscapes are outstanding example
Background: Isocapnic hyperventilation (IHV) shortens recovery time after inhalation anaesthesia by increasing ventilation while maintaining a normal airway carbon dioxide (CO2)-level. One way of performing IHV is to infuse CO2 to the inspiratory limb of a breathing circuit during mechanical hyperventilation (HV). In a prospective randomized study, we compared this IHV technique to a standard emer
Fastigheter anses på grund av dess unika egenskaper att vara en av de bästa skattebaserna, och i takt med globaliseringens acceleration blir betydelsen av skatteintäkter från denna skattebas allt större. I Sverige har skatteuttaget från denna skattebas trendvis minskat med åren, något som sticker ut på ett internationell plan. Syftet med rapporten är att jämföra olika fastighetsbeskattningsmodellReal estate is regarded as one of the best tax bases due to its unique characteristics. As globalization accelerates, the importance of this tax base is increasing. In Sweden, the tax revenue from real estate has trended downward over the years, something that stands out internationally. The purpose of this report is to compare different property taxation models for detached single-unit propertie

Abstract Authors: Maria Silversand och Maria Svensson Title: Praktiken ger liv åt teorin - skoltrötta ungdomar Supervisor: Johan Cronehed The purpose of this assignment has been to investigate how the definition of “school fed” has been construed in newspaper articles and if, and how, it has changed over time. From our question formulations which were; how the concept ”school fed” is defined, mea
Monocular depth estimation (MDE) models have undergone significant advancements over recent years. Many MDE models aim to predict affine-invariant relative depth from monocular images, while recent developments in large-scale training and vision foundation models enable reasonable estimation of metric (absolute) depth. However, effectively leveraging these predictions for geometric vision tasks, i
