Several governments recently adopted strategies to facilitate the development of artificial intelligence (AI), one of the reasons being the pursuit of sustainability – a claim with little scientific grounding so far. In this thesis, I strived to outline the scope of AI’s potentials by showing i) the limits of its theoretical and practical usefulness and ii) the political barriers to using it for s
Fler företag ser värdet av att implementera ett CRM-system för att få konkurrensfördelar. Implementationen har visat sig vara en svår process och en majoritet anses misslyckas. Genom att identifiera kritiska framgångsfaktorer har akademin försökt underlätta för framtida implementationer genom att peka på faktorer som bör beaktas för en lyckad implementation. En stor del av denna litteratur lägger
This master thesis in library and information science is centered around two reading circles taking place at the libraries of Swedish upper secondary schools. The aim of the thesis is to study how the participants (ages 16-18) in the reading circles reflect on their own reading practices and their identities as readers. One main point of the thesis is that reading circles are forms of reading comm
The main purpose of this master's thesis is to explore how public libraries in Sweden work to increase digital skills among older people. This is done by studying social practices in digital technology workshops at local meeting places for older people. Public librarians participated as instructors and the purpose of these workshops was to enhance the digital skills of older people. This stu
The development of sports within the European Union (EU) has been blooming the latest century, especially in the football sector, which has been transformed into a multi-billion industry. The development of European football has attracted investors outside the EU into heavy investing in football clubs across Europe. This has enabled purchases of new talents and high profile players for astronomica
This thesis investigates the effect of commuting time on labour supply using US household survey data. To circumvent biased estimates as working hours and commuting time are jointly determined by the worker, a first differences approach is carried out, in which changes in the commute are assumed to be exogenous. The estimates suggest that there is no causal effect on labour supply that can be deri
In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. A campaign of measurements is carried out in an active i
In the emerging trend of smartphone use and a rising demand for solar photovoltaic (PV) power worldwide, this master thesis project explores the potential to utilize commercially available fisheye lens optics in combination with a smartphone camera to capture and analyze local shading conditions. Photogrammetric studies involving hemispherical sky photos have since long been used for environmental
Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
Bakgrund. Prioriteringar är nödvändiga inom hälso- och sjukvården eftersom samhällets resurser är begränsade. Hälso- och sjukvårdspersonal har alltid behövt prioritera mellan olika behandlingar och patientgrupper. Logopeder är också en av de professioner som dagligen ställs införa svåra prioriteringsval mellan patienter. Trots detta finns det inom logopedi få exempel på systematiskt organiserade p
Solving finite-sum minimization problems could be done by the use of a gradient descent algorithm. The algorithm evaluates the gradient with respect to the current state of the parameters and updates the parameters in the direction of the steepest descent. For certain problems, evaluating the full gradient at every iteration is computationally heavy and the gradient of the objective function is th
Unmanned vehicles need robust systems to ensure the safety of the vehicle and its environment. Being able to find and avoid perilous situations is paramount to such a system. In this paper we suggest an unsupervised image-based anomaly detection algorithm using a variational autoencoder and a superpixel segmentation algorithm, which is adapted to the maritime obstacle detection task. The algorithm
This paper explores the use of an automated pipeline to construct synthetic (artificially derived) trip data from aggregate socio-demographic sources to build a simulation of individual vehicles interacting with one another. The study shows that quality data sources are required in order to do this effectively and accurately. It is shown that aspects of typical patterns and behaviours may still n
In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. Here we investigate an alternative scenario, that is whether this proposed planet can exert observable perturbation on Main Belt astero
Bakgrund: Personer med allvarlig psykisk sjukdom riskerar minskat engagemang i dagliga aktiviteter, främst gällande förluster av mängden individuellt meningsfulla aktiviteter. Samtidigt har arbetsterapeutiska interventioner som möjliggör engagemang i meningsfulla aktiviteter visat sig vara stödjande för personernas personliga återhämtning. Det finns dock bristande kunskap gällande vilken betydelse
Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t

The goal of this Master's Thesis is to successfully detect and classify humans in a LiDAR data stream. The focus of the Thesis is on the detection and classification, not on the LiDAR technology. To classify humans machine learning was used and to train the machine learning model we collected our own data and annotated it. A custom software was made for speeding up the annotation process.
