In this thesis, we investigate the water-wave problem for two-dimensional steady waves with constant vorticity. We introduce a new approximate model that, in its simplest form, reduces to a planar dynamical system. We then analyze this system for various energy levels and vorticity constants, studying its phase portraits to determine the locations and types of solutions that arise. In the unidire
This bachelor’s thesis examines five selected works of art by the Swedish painter Leander Engström (1886–1927), created between 1915 and 1919. This period is generally regarded as the most significant phase of Engström’s artistic production and was shaped by his time spent in Abisko, as well as by a romantic relationship that coincided with an especially vivid and expressive phase in his work. Eng
Environmental simulations are increasingly used in urban planning to assess parameters that influence adequate living conditions in densification projects, such as daylight access, noise exposure, wind comfort, and flood risk. These simulations rely on geospatial data and on the representation of the urban environment through 3D city models. However, in current planning practice, simulation result
Byggnader med synnerligen högt kulturhistoriskt värde kan förklaras som byggnadsminnen av länsstyrelsen. Ett byggnadsminne är särskilt skyddat från ingrepp genom skyddsbestämmelser i kulturmiljölagen (1988:950) (KML). Även i plan- och bygglagen (2010:900) (PBL) finns skyddsbestämmelser för byggnader som är särskilt värdefulla från en kulturhistorisk synpunkt. Medan länsstyrelsen genomför all myndiBuildings of exceptionally high cultural and historical value can be designated as listed buildings by the County Administrative Board, granting them special protection against alterations through protective provisions in the Historic Environment Act (1988:950) (KML). Additionally, the Planning and Building Act (2010:900) (PBL) contains protective regulations for buildings that are classified as p
Sea ice is strongly impacted by global warming, and its decline further alters the global climate. Climate models are important tools for examining those future sea ice changes and the interaction of sea ice with other Earth system components such as the atmosphere and the ocean. Typically, these components are simulated with separate codes. The interaction between these components is typically mo
Ever since the end of the second world war, Europe has been lagging behind the United States in rocket development. In particular in the last 10 years, the technological gap and American competitive advantage have grown thanks to SpaceX’s development of reusable launch vehicles. A key enabler for the reusability of booster stages is precise rocket engine control. This thesis addresses the objectiv
This thesis investigates probing antennas within a small shielded test enclosure for IoT, Internet of Things, products for the detection of manufacturing deviations. The small enclosure forces the transmitter and receiver to be in the near-field. Shielding of the enclosure additionally generates a multipath environment, which becomes sensitive to displacements of objects such as wires or metallic
The aim of this master's thesis is to establish material models for three rubber materials using macroscopic data collected using Digital Image Correlation, DIC. DIC is a non-contact optical technique for measuring strain and displacement in a material by tracking points on a material during the deformation process.\\ The rubber materials are tested in both uniaxial tension and compression, fr
De utmaningar som dagens och kommande generationer står inför, till följd av klimatförändringarnas konsekvenser, har inga motsvarigheter i historien. Därför utmanas vårt tänkande och agerande från grunden. Som en följd av detta finns en rörelse som försöker påverka politiken och samhället i en mer hållbar riktning: klimataktivisterna. I oktober 2024 friades en klimataktivist av Stockholms tingsrätThe challenges faced by current and future generations as a result of the impacts of climate change are unprecedented. Therefore, our modes of thinking and acting are being fundamentally challenged. As a result, a new climate movement has emerged, calling on politicians to ensure sustainable policies and societies. In October 2024, a climate activist was acquitted by the Stockholm District Court o
Traffic congestion is a persistent problem in modern urban environments, causing delays, increasing pollution, and negatively affecting the quality of life of millions of city dwellers. As urban populations grow, the need for intelligent traffic man- agement systems becomes more pressing. This thesis presents a novel approach to real-time traffic management using edge computing in conjunction w
Upphovsrättens grundläggande syfte är att säkerställa en rimlig balans mellan skyddet av upphovsmannens rättigheter och möjligheten att utnyttja kulturella och kreativa verk i samhället. Frågan om hur ersättningen till upphovsmän och utövande konstnärer bör fastställs vid överlåtelser av rättigheter är central inom upphovsrätten. I syfte att bidra till en fungerande digital inre marknad, stimuleraThe fundamental purpose of copyright is to ensure a fair balance between the protection of authors’ rights and the ability of society to access and exploit cultural and creative works. The question of how remuneration for authors and performing artists should be determined in cases of transfer of rights is a central issue within copyright law. With the aim of contributing to a well- functioning di
De tidigaste bevarade svensk-norska dokumenten om Lappmarken skrevs på 1300-talet, och därefter finns ett växande historiskt källmaterial som förser med en relativt tydlig bild av samernas rättigheter genom tiderna. Statens intressen förändrades med industrialiseringens framväxt, och avvittringen av Lappmarkerna påbörjades. Samiska försörjningssätt urholkades av staten under 1880-talet, och LappmaThe Sámi people's legal history can be found in written documents dating back as far as the 14th century. With industrialization, the State’s priorities underwent significant changes, and land that had once held little value to the State was now seen as economically beneficial. It was made clear that land traditionally used by the Sámi population belonged to the State. The Reindeer Grazing Act
