1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction
Master-uppsats, KTH/MaterialvetenskapSammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and the content of non-metallic inclusions (NMI). Achieving cleanliness is a gradual process where all the steps of the production process are inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

2. Dark Ecology: Obscurities Illuminated
Master-uppsats, Uppsala universitet/Statsvetenskapliga institutionenSammanfattning : This study investigates “dark ecology” – an ecological theory formulated by Timothy Morton, based on an object-oriented ontology and claimed to offer a new perspective on how humans can and should coexist with other “objects” in the world in a better, less hostile way. Dark ecology is a critique of both an anthropocentric and a biocentric worldview, aiming to erase the dichotomy between human/nature and subject/object. LÄS MER
3. Using artificial intelligence to improvetime estimation for project management
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : Time estimation is an important aspect in project management. Failure to make accurateestimates can lead to large consequences. Despite this, humans tend to make fairly inaccurateestimates when tasked to, often underestimating the time something will take substantially. LÄS MER
4. Norra polcirkelns uppvärmning och ännu varmare maktkapplöpning
Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionenSammanfattning : Today the climate in the arctic regions are changing at a rapid rate, faster than any speed previously recorded in human history but how is it impacting the geopolitical situation in these regions? New territory is being created by the ice melting and new natural resources are being found, how can this impact the current situation? This study looks at and discusses the current geopolitical situation in the Arctic using two theories from international relations, realism and liberalism and how the situation can develop using these theories. From a realist standpoint it is a balance of power held in check primarily by nuclear weapons. LÄS MER
5. Decay Chains of Fast Alpha Emitters in the Actinide Region
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER
