This thesis presents an application of machine learning techniques in a search for a high-mass resonance particle decaying into top quark pairs in high energy dijet events using the ATLAS experiment at the Large Hadron Collider. Top tagging is applied to the dijet events to select the events with top signature and suppress the background, increasing the sensitivity of the search. All the data used

Digitalization is changing the conventional face of business, posing ethical questions with regards to how businesses create, collect, use, and store data as part of their everyday business activities. Moreover, because of the pervasiveness of data technologies and unpredictability of their effects on society at large, the complex network of stakeholders affected by data handling is increasing exp

Ökad noggrannhet vid ATLAS experimentet Var kommer vi ifrån? Vad hände i Big Bang? Detta är exempel på några av många obesvarade frågor inom fysik. ATLAS är ett experiment vid CERN (Europeiska organisationen för kärnforskning), där tusentals forskare samarbetar med att undersöka produkterna från högenergetiska protonkollisioner, för att få svar på dessa frågor. En vanligt förekommande produkt The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. To perform these searches, many ATLAS analyses look

While it is fairly certain that people have experienced emotions all throughout history, it is less certain how we understand historical expressions of emotion in a modern context and what value such an understanding could bring to examinations of the link between power and the people. The aim of this master thesis is to gain deeper understanding regarding the relationship between human emotions a

Secondary clients: a discourse analysis of affinity and kinship In recent years, a trend has developed in care-giving systems. It was previously thought that care for our elderly, physically disabled or chronically ill relatives and loved ones, was to be provided by and cared for in institutions. As of now, we see a retrograding trend where a lot of the treatment and/or care is to be provided in

The construction sector is often criticized for its lack of efficiency and quality.When the construction industry is compared to the rest of the domestic manufacturing industry, the general conclusions of the industry’s low efficiency is confirmed. The purpose has been to clarify why there is no sustainable building, despite the well-developed technology that now is available. The report also exam

Popular summary: Hydrocarbons, ground water and economic minerals occur in pores (voids) between sediment grains, which later may form more solid and less porous sedimentary rocks. Thus porosity is a term that describes the abundance of these pores and can be defined as the quantity of oil, gas, water and economic minerals a rock can hold and it is expressed as percentages (%). The other importa

Tre grustag undersöktes i nordöstra Tyskland, Kreuzbruchhof, Fritscheshof och Spargelberg. Syftet var att rekonstruera den senaste glaciala aktiviteten i området. Tolkningarna och således rekonstruktionen grundar sig till största delen på sedimentologiska och strukturella undersökningar. Kreuzbruchhof består mestadels av glacifluviala sediment med undantag för några mindre diamikta enheter tolkadeThree gravel pits near Neubrandenburg, NE Germany, were investigated - Kreuzbruchhof, Spargelberg and Fritscheshof. The investigated gravel pits are situated in an undulating kame landscape 150 km south of the Baltic Sea. The aim of this study was to reconstruct the Late Weichselian history (e.g. deglaciation of the Pomeranian ice sheet) of the area. Reconstruction was based mainly on sedimentolog

This means a municipal website that is adjustable and easy to navigate, especially for users in need of accessibility tools to browse the web. To create this prototype, we first created two separate prototypes that closely resembled each other. These two prototypes were then compared to each other and

Efter valet 2022 har den nytillträdda svenska regeringen, med stöd av Sverigedemokraterna, aviserat att de avser förbjuda politiska partiers från att bed-riva lotteriförsäljning. För det nya oppositionspartiet Socialdemokraterna och dess ungdomsförbund skulle det medföra betydligt minskade intäkter. Samtidigt gäller föreningsfrihet enligt svensk grundlag. I lagstiftningsarbetet har föreningsfrihetAfter the 2022 election, the newly appointed Swedish government, with the support of the Sweden Democrats, announced their intention to prohibit political parties from conducting lottery sales. For the new opposition party, the Social Democrats, and their youth organization, this would result in significantly reduced revenue. At the same time, freedom of association is protected under the Swedish

MAX IV kommer bli världens första ultrabriljanta synkrotronljusring. Ringen använder magneter för att böja elektroners bana på ett helt nytt sätt och kommer därför producera röntgenljus i strålar som blir finare och mer fokuserade än vad någon annan anläggning i världen kan göra. Röntgenstrålarna leds ut i långa rör för att kunna användas till experiment. Ett av strålrören heter NanoMAX och det koX-rays have been used for imaging for over 100 years due to their unique interaction properties with matter that allow them to penetrate samples and reveal detailed structural information on the atomic scale. NanoMAX is one of the first beamlines to be developed at the new Swedish synchrotron radiation source MAX IV. It will use high brilliance, coherent X-radiation to utilize these properties ful
