This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. In an esophagectomy, the cancerous part of the
CO 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
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
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
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
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
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
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
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
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 nol
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
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
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
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
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
Syfte: Syftet med studien är att identifiera vad som definierar ett framgångsrikt byggprojekt och vilka framgångsfaktorerna är för att säkerställa att projektet enligt beställaren blir framgångsrikt. Vidare är syftet att undersöka hur kravställningen i de administrativa föreskrifterna påverkar ett projekts framgång. Frågeställningar: • Hur definierar beställaren ett framgångsrikt projekt? • Vilka
The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. The research commenced with the execution of three similar experiments, further calle
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
