Att göra datorsimuleringar av komplexa kemiskt reaktiva system, såsom gasbrännare och motorer, kan vara tidskrävande. Reaktornätverk är en simuleringsmetod där beräkning av detaljerade kemiska reaktioner separeras från beräkning av flöde vilket ger en kortare beräkningstid. En metod för att automatiskt konstruera sådana nätverk har utvecklats och testats på en brännare för gasturbiner och på en öpThe main goal of this thesis was the development and application of a method to construct reactor networks based on pre-calculated flow fields for combustion systems. Computational fluid dynamics (CFD) was used to calculate flow fields for the Sandia piloted jet flame D and a Siemens SGT-800 gas turbine burner rig. Two different combustion models were tested in the computational fluid dynamics cal

Bakgrund: Emergency Teamet skickar ut ERH-Kits då en efterfrågan från kunden uppstår, exempelvis efter en katastrofsituation. Emergency Teamet har blivit kritiserade för att inte ha svarat tillräckligt snabbt på efterfrågan och därför har Executive Director för UNFPA gett nya direktiv för att UNFPA ska svara snabbare och skapa bättre förutsättningar för att leverera snabbt i katastrofsituationer. Background: The Emergency Team within UNFPA operates when crisis strikes by distributing ERH-Kits to people in need. The Emergency Team has in the past been criticized of not responding rapidly enough to requests for ERH-Kits and the Executive Director of UNFPA has given new directives that UNFPA needs to become more responsive in its activities and create better prerequisites to deliver fast in e

Benevolent, but uninformed : a qualitative interview-study on trans-inclusive behavior within the Swedish social services. The transgender community is a heterogenic group of gender diverse individuals who are at greater risk of societal oppression and maltreatment by the welfare system. The aim of this bachelor’s thesis is to assess the degree of trans-inclusive behavior of five social service w

Hur kan biologisk mångfald gynnas i en företagspark? Hur ska både människor och natur få plats i en alltmer urbaniserad värld? Kunskapen om hur biologisk mångfald påverkas av byggnadsprojekt behöver öka, samtidigt som stadens gröna områden behöver stödjas och utvecklas för att gynna fler arter. I mitt examensarbete har jag undersökt förutsättningarna för fåglar och pollinerande insekter i företagUrbanization is causing impact on biodiversity and ecosystem services globally, due to disturbance, fragmentation and loss of habitats as the proportion of urban settlement increases. Actions for enhancement of biodiversity in urban spaces become important to achieve a sustainable urbanization. Wihlborgs Fastigheter AB, a housing company in the Öresund Region, has installed eleven nest boxes for b

The efficiency in an internal combustion engine ranges from 25% to 45%. About 50% - 85% of the overall energy losses in a combustion engine is heat which is either cooled away by the vehicle's radiator or blown out with the exhaust gases. The heat has to be cooled off by the vehicle's cooler and this energy is never put into use again and is therefore called 'waste heat'. Even if a

In this report the motor side of a converter driven AC-locomotive is studied and modeled. The motor side consists of an asynchronous electrical engine, an indirect self controller, a voltage converter, a Pulse Width Modulator(PWM) and the train mechanics. The converter is supplied with voltage from a DC-link. The link is connected to a line converter which transfers energy from the railway net to

Uppsatsen syftar till att utreda ersättningssystemet av rättegångskostnader i förvaltningsprocessen och hur väl det stämmer överens med rätten till en rätt-vis rättegång. Särskilt kommer avgörandet HFD 2022 ref. 10 att redogöras för och kritiseras. Arbetet tillämpar en kritisk rättsdogmatisk metod. I förvaltningsprocessen gäller som huvudregel kvittningsprincipen, som inne-bär att parterna bär siThe study’s ambition is to examine the order of reimbursement of legal costs in the administrative law procedure and how it compels to the right of a fair trial. In particular, the ruling by the Supreme administrative court (HFD 2022 ref. 10) will be exposed and criticized. The paper uses a critical legal dogmatic method. In the administrative procedure, the principle of set-off applies, which me

The study is an empirical analysis of what drives the sentiment towards a tax-funded Universal Basic Income (UBI) implementation in 12 European countries, both on an individual and country level. The two core research questions are: How do the subjective perceptions of household income influence the sentiment towards the implementation of a basic income scheme on an individual level? and how does

Vi testar om det går att bygga generaliserade modeller för tidsseriedata och om den framgångsrika AI-arkitekturen Transformer kan hjälpa oss med detta. Vår slutsats är att sådana modeller är möjliga, men att vi inte kan fastställa huruvida Transformer är värd mödan eller inte. Alla typer av mätningar i vilken utveckling över tid är av intresse kan porträtteras som tidsserier. Dessa är sekvenser aA reliable forward prediction of time series data is essential for optimising resource allocation, mitigating risks, and enhancing strategic decision-making across various domains. However, the limited historical data available can pose a challenge for accurate modelling. Conversely, transformer architectures, renowned for their success in natural language tasks through zero-shot inference, demons

In cancer cells, when two different genes are rearranged and joined, a fusion gene results and can act as a tumour driver. While many programs to predict fusion transcripts based on RNA-sequencing data do exist, the predictions contain many false positives without underlying genomic rearrangements. With the release of a new fusion validation pipeline to address this shortcoming, we have created a

Fram till för några decennier sedan, innan ordförande Maos död, var Kina avstängt från resten av världen. Idag är Kina världens näst största ekonomi och en mycket attraktiv destination för utländska investeringar. Medan denna ekonomiska explosion har medfört enorm teknikutveckling för Kina, har vissa observatörer påstått att dessa framsteg har kommit genom det som kallas "tvångsöverföring av Up until a few decades ago, before the death of Chairman Mao, China was closed off from the rest of the world. Today, China is the second largest economy in the world and a very attractive destination for foreign investment. While this economic explosion has brought with it tremendous advancement in technology for China, some observers have alleged that these advancements have come through what is

We live in a world built on consumerist values and a spatial rationale of capital accumulation. This modern society has led to architecture thriving through super consumption and super production ultimately leading to the generic. Cities and spaces that were usually rich in variation and texture have now become an architectural melting pot. Architecture has become smooth, simplified and reduced to

Background and Hypothesis: To clarify, in a large, representative, longitudinal sample, the rate and predictors of diagnostic conversion from Bipolar Disorder (BD) to Schizophrenia (SZ) and from SZ→BD. Design: From individuals born in Sweden 1950–1995 and living there in 1970 or later, we identified at least one initial diagnoses of SZ (n = 8449) and BD (n = 8438) followed for a minimum of 10 and

Victim blaming is a harmful but quite pervasive phenomenon occurring in contemporary societies. When people engage in victim blaming, they shift the burden of the harmful act from the perpetrators and place it upon the victims instead. This article explores how the discourse on moral responsibility can help make sense of victim blaming. The distinction between moral responsibility and blameworthin

This essay investigates the relation between economic growth and happiness, with regard to the central position of economic growth on the political agenda in the Western world today. In political argumentation it is often claimed that economic growth and existing economic conditions are challenged by processes of change, especially economic globalisation and "de-industrialisation". In th

Prediction of flood and evaluation of the impact of climate change in a catchment needs to be correctly estimated, which can be accomplished by hydrological modelling in HEC-HMS. In this paper, the objectives were to gain an understanding of the rainfall-runoff process and estimate the flood frequency curve in the Kävlinge River Basin. However, due to the complexity of a catchment, models should b

Efterfrågan på biobränslen ökar som ett resultat av höjda klimatreducerande ambitioner som syftar till att ersätta användningen av fossila bränslen. För att möta den ökande efterfrågan uppmärksammas alternativet att odla energigrödor på jordbruksmark för produktion av biobränslen allt mer. Eftersom jordbruksmark är en knapp resurs kan konflikter uppstå mellan livsmedelsproduktion och biomassa för The demand for biofuels is increasing as a result of increased climate mitigation ambitions aiming to replace the use of fossil fuels. To meet the increasing demand, energy crops grown on agricultural land used to produce biofuels is getting more and more attention. Since agricultural land is a scarce resource, conflicts can arise between food production and biomass for biofuels, making it essenti

En parts tillgång till information i en rättegång blir ofta avgörande för hur väl denne kan tillvarata sin rätt. Det är som huvudregel upp till parterna själva att anskaffa informationen, men det finns undantag. För de fall en informations-innehavare vid den utomprocessuella informationsanskaffningen inte med-verkar kan domstolen ibland bistå med informationsanskaffningen. InformationsanskaffningA party's access to information is crucial within the litigation process. In the event of a legal dispute, the main rule is that the parties must take care of gathering the necessary information on their own. However, there are exceptions. For those cases where the information holder does not cooperate, the court can assist with the information-gathering. Obtaining information in the event of
