In order to investigate this thesis’ purpose, a quantitative method and deductive approach has been employed. This thesis is based on previous research which has investigated what different ri

Teleportering – att förflytta människor och ting mellan två platser utan att de faktiskt reser mellan dem – har länge varit en del av science fiction berättelser, som exempelvis Star Trek. Fram till 90-talet så förblev teleportering en science fiction dröm, men 1993 så föreslog Charles H. Bennett och medarbetare ett sätt att få teleportering att bli verklighet. 1997 så utfördes ett experiment i ÖsQuantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. First, we studied

Delningsekonomi är ett koncept som har utvecklats för att frångå det så kallade ”slit- och slängsamhället”. Givet konceptets innebörd, att dela underutnyttjade tillgångar istället för individuellt ägande, finns det svårigheter att bedriva en verksamhet och samtidigt ha ekonomisk bärighet. Det beror bland annat på individers beteende samt betalningsvilja för att dela istället för äga, och därmed ocSociety intends to become more sustainable and in the work towards becoming more sustainable, circular models have a contributing role in the transition. Combining sustainable consumption with the sharing economy concept could help to tackle challenges such as: the growing amount of waste and climate change by reducing the extractions of resources and regenerated materials within the economic syst

Det finns många komplexa sjukdomar som i dagsläget är mycket svåra att diagnostisera. Det är inte ovanligt att när dessa sjukdomar slutligen diagnostiseras så är det för sent för att kunna göra någonting åt det. Men med en ny teknik kan det bli möjligt att ställa diagnoser i tid. Tekniken grundar sig i att, från ett vanligt blodprov, identifiera vilka proteiner som finns i blodet varpå sedan låta When using antibody microarrays to diagnose diseases, the process of quality control of the microarray data is an important step. Currently, a part of this process is performed manually by visual inspection. In this master project, we aim to automate the quality control in order to make it reproducible, as well as to find out which properties of the data that have the most to do with its quality.

I den statliga utredningen, Ett snabbare bostadsbyggande, undersöktes hur utnyttjandet av byggrätter kunde effektiviseras. Underlaget var dock tämligen begränsat, vilket skapade idén till den här rapporten. I vilken utsträckning förekommer outnyttjade byggrätter och varför utnyttjas de isåfall inte? Syftet med denna rapport är att utreda om det finns outnyttjade byggrätter med ändamål flerbostadsIn the public report, Ett snabbare bostadsbyggande, a research was made to find out how the utilization of undeveloped building rights could be made more efficient. However, the material on which the research was based was found insufficient, which created the idea for this report. To what extent do undeveloped building rights occur and what are the reasons? The purpose of this report is to exami

In the next step, the difference in difference approach has been used to explore the oil price crash in the fourth quarter of 2014 so as to find the difference in the average discount on the assets of

Ända sedan 1781, när William Herschel upptäckte Uranus, så har astronomer letat efter planeter som ligger ännu längre ut. Solsystemet är ett stort ställe, så om man vill hitta någonting så krävs lite vägledning till var man ska leta. 2016 publicerade astronomerna Konstantin Batygin och Mike Brown en studie om små objekt utanför Neptunus, där de hade upptäckt att många av de här himlakropparnas banClustering of orbital characteristics for distant Solar System objects has been proposed to indicate the presence of a ninth planet. Simulations show that the planets orbit would have to have a mass of 5–10 Solar masses, a semi-major axis of 400–800 AU, an eccentricity of 0.2–0.5 and an inclination of 15–25°. Simulations of a planet scattering off a giant planet into a highly eccentric orbit, show

Elektroner, fast de inte kan ses med blotta ögat, har en grundläggande betydelse i vår vardag. Inom vår natur finns många exempel på system av elektroner som interagerar med varandra, så kallade flerelektronsystem: från materialet i elektronikkomponenter ner till några av de minsta beståndsdelarna i vår natur, atomer. Vi har utvecklat en Greenfunktion-teori för att beskriva material och flerelektrAn ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. The formalism is applied to four model systems within GWA: a three-

I dagens samhälle är ett hållbart alternativ till fossiltbränsle högt efterfrågat. Biobränsle är ett alternativ, men om detta alternativ ska vara optimalt, måste det härstamma från ett billigt och lättillgängligt material, som t.ex. cellulosa. Cellulosa finns i bl.a. växtcellväggar och är uppbyggd av sockerenheter (glykos) i en väldigt stabil struktur vilket är en bra egenskap när den sitter i växIn this thesis the enzyme Lytic polysaccharide monooxygenase (LPMO) is investigated. The LPMOs have captured the interest of the biofuel industry due to their ability to boost the breakdown of cellulose. Researchers have progressed in mapping out the mechanism behind this oxidative reaction. However, there are still many uncertainties concerning the intermediates involved and the role of certain a
