The active phase of Pt(110) during catalytic CO oxidation

En förbränningsmotor, som den i din bil, har inte tillräckligt med syre för att fullständigt förbränna bränslet till koldioxid och vatten. Därigenom frigörs kolväten, kolmonoxid och kväveoxid. 98% av dessa giftiga biprodukter kan omvandlas till mindre skadliga ämnen med hjälp av en katalysator. En katalysator använder grundläggande oxidation och reduktion för att omvandla de giftiga utsläppen fråCO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. Oxidation catalysts such as Pt, Pd and Rh are frequently used as catalytic converters for CO oxidation i

Local voltage control in a low voltage grid with high photovoltaic penetration

This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E.ON, has noticed problems concerning high voltage

Shower Routine Creation: Application Design in a User-Centered Process

A shower routine is a sequence of instructions that can be executed by a smart shower. This report explores how interfaces for creating shower routines can be designed. It further investigates the features that users prioritize in such an interface and how shower routines can enhance the shower experience. Based on Orbital Systems’ app My Water, prototypes for various design so- lutions were creat

Virtual H&E Staining Using PLS Microscopy and Neural Networks

Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts. This

Bilingualism and Event Conceptualisation Patterns: Conceptual Transfer in Swedish-English Bilinguals

In this paper, the event conceptualisation patterns of Swedish-English bilinguals are examined. Swedish and English differ from each other with regard to the existence of grammatical aspect, which previous work has shown to affect how speakers conceptualise motion events. In bilingual speakers, we expect to see cognitive transfer from either, or both, languages. In the present study, a within-subj

Walk It Like You Talk It: En Kvalitativ Studie om Etiska AI-Strategier

Research question: How are organizations integrating ethical and strategic considerations into their approaches to AI implementation? Purpose: The purpose of this research is to systematically map ethical and strategic themes relevant to Artificial Intelligence Systems within the business context from a practitioner standpoint. This study aims to contribute to the understanding of this research fi

Bidding Farewell to the Ancient City of Ashur: A Qualitative Case Study of the Social and Cultural Impacts of the Makhoul Dam in Iraq

This qualitative case study explores through semi-structured Interviews the social and cultural impacts of the Makhoul Dam, planned as part of Iraq’s climate change mitigation work. It was based on the research question: How do local individuals experience the Makhoul Dam’s impact on their home environments including the surrounding archaeological sites? And supported by the two operational questi

Analys av klimatpåverkan från ventilationssystem vad avser utformning och systemval i kontorsbyggnad

Bakgrund: Byggsektorn står för en väsentlig del av Sveriges växthusgasutsläpp, motsvarande 21% enligt Boverket. För att nå Sveriges klimatmål med minst 85% minskning av nettoutsläppen till 2045 krävs hållbara byggnader och installationsdesign, särskilt inom ventilation och komfortkyla. Livscykelanalys (LCA) är en metod som stödjer bedömningen av produkters miljöpåverkan och leder byggbranschen motBackground: The building industry is responsible for a big part of Sweden's greenhouse gas emissions, around 21% according to Boverket. To meet Sweden's climate goals, which aim for at least an 85% reduction in emissions by 2045, we need environmentally friendly construction methods, especially in ventilation and cooling. Life Cycle Analysis (LCA) is a way to assess how products impact the

Utvärdering av olika farthinder på Lunds huvudgator utifrån bussarnas perspektiv - En jämförelsestudie

Varje år sker en ökande urbanisering och med fler människor i en stad så ökar trafikbelastning och därmed risken för olyckor. Därför är det viktigt att kommunerna arbetar med att skapa trafikmiljöer som är säkra för gående, cyklister, bilister och kollektivtrafiken. Trafiksäkerhet och komfort är två viktiga parametrar att arbeta med eftersom dessa de bidrar till de transportpolitiska målen och nolEvery year there is an increasing urbanization and traffic load, which means that we have to create traffic environments that are safe for pedestrians, cyclists, vehicles and public transport. Traffic safety and comfort are two important parameters that are worked with, and the aim is to increase traffic safety and comfort which contribute to the transport policy goals and the zero vision where no

Multivariate time series classification in time-sensitive environments using deep learning

Elektriker och servicepersonal vistas frekvent inom områden där högspänningskomponenter förekommer. Detta arbete undersöker möjligheten att utnyttja maskininlärning, mer specifikt djupinlärning som grund i ett system som varnar elektriker och servicepersonal om strömförande komponenter och ledningar.In this thesis, sensor data from substations and distribution centrals in Sweden and Germany is analysed and used to predict the voltage environment which the device is within. The theory needed for understanding the measured values is explained, and the notion of multivariate time series is introduced along with the reason for using deep learning to solve the problem at hand. Several ways of extr

Using Neural Radiance Fields and Gaussian Splatting for 3D reconstruction of aircraft inspections

The rapid evolution of machine learning techniques has revolutionized computer vision, particularly with the introduction of Neural Radiance Fields (NeRF) and the optimization of 3D Gaussians for rendering novel scene views. These methods, such as NeRF and Gaussian Splatting, have demonstrated success in synthetic data scenarios with consistent lighting and well-captured scenes. This research expl

Sustainable water management in the Jordanian phosphate mining industry

Jordan is a very water stressed country with very low annual renewable water resources per capita. The effluent wastewater from two Jordanian phosphate mines (the Al-Abiad and the Eshidiya mine) was analysed and compared with the national and international standards and regulations for irrigation and industrial effluent wastewater. The water management at the mines was examined from a sustainable

Börsdumpen, ett missfoster och Darth Vader

Research question: How are metaphors used in Börspodden and how are they expressing biases? Purpose: The purpose of the study is to analyze the metaphoric depiction of biases in podcast within the category of business. This objective is achieved through a discourse analysis to identify the underlying biases that can be interpreted from the use of metaphors. Methodology: The purpose of the study

Notus

The bachelor course AAHF30 - Architecture in the Contemporary explores various digital processes and fabrication techniques to address critical climate change issues through an individual design in the form of a naturum. The Notus naturum project originated from observing a site characterized by flat terrain and strong winds, prompting an investigation into wind's impact on ecosystems and clim

Berättelser om verkligheten : från magnetband till mp3

Swedish public service radio has during its almost 100 years undergone several transformations due to technical, societal and cultural changes. A transformation still in motion can be attributed to the arrival of the internet, the digitalization of the recording, storage and distribution of sound, as well as the fast paced evolution of the global media landscape. When the mp3-file and the internet
