The use of bio-fuels is becoming more important because of the environmental benefits associated with these fuels. Deactivation of SCR catalysts applied in bio-fuel plants is a major problem due to the high potassium content of bio-fuels and therefore, great potential lies in finding regeneration processes that can be used commercially. Exposing the catalyst surface to sulphate groups generated by
In this study we compare two types of Large Eddy Simulation (LES) turbulent combustion models with experimental data for a low swirl stabilized turbulent lean premixed flame. Such flames are a great challenge to numerical simulations since they are unsteady and sensitive to boundary conditions, and details of the experimental set-up. The two classes of LES turbulent combustion models considered ar
Abstract in UndeterminedPurposeThe purpose of this article is to explore and classify themes and challenges in making urban freight distribution sustainable.Design/methodology/approachThe study has a cross sectional design which started by a narrative literature review and analysis of a sample of related literature (like peer-reviewed articles and EU (European Union) documents). It ended with comp
The Baltic Sea Region is rapidly becoming one of the world’s more competitive regions. The region is capitalising on its strengths and making the most of its diversity to stimulate innovation, build a strong pool of skilled labour and foster entrepreneurship. A deep spirit of co-operation and integration has led the Baltic Sea countries to set up ambitious governance frameworks to pursue economic
In recent years, technological developments have been the focal point of the discussion in the shipping industry. The two main topics have been a general discussion on IT security and a discussion about autonomous ships. Concerning IT security, the discussion has been focused on the industry's knowledge in the field and preparedness for any attacks or mishaps that can affect companies that ar
In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. In this bachelor thesis, these droplets were numerically stud
Offentligt anställda har enligt regeringsformen krav på sig att iaktta saklighet och opartiskhet för att upprätthålla allmänhetens förtroende för staten. För att säkerställa att bestämmelserna efterföljs, har lagen om offentlig anställning införlivat regler om bisysslor. Lagstiftningen kompletteras av vidare bestämmelser i de statliga kollektivavtalen. En bisyssla kan omfatta i princip vilket åtagIn order to maintain the public’s trust, the Instrument of Government dictates that all public employees must act objectively and impartial. To ensure compliance with this regulation, the Public Employment Act has incorporated legislation on incidental employment. Incidental employment refers to any employment, assignment or activity that may harm the reputation of the authority. This is further r
Studies on how small states act within the international system are usually performed using the major theories in international relations. After Russia’s invasion of Ukraine in 2022, Sweden applied for a membership in the North Atlantic Treaty Organization (Nato). This thesis’s purpose is to gain knowledge on how strategic narratives were used to legitimize policy changes in a nation that has been
Denna uppsats är skriven på uppdrag av Lunds tekniska högskola och Myndigheten för samhällsskydd och beredskap. Uppdraget består av att modellera antalet dödsbränder som sker i Sverige över tid, samt undersöka ifall det har skett någon signifikant förändring. Detta görs utifrån ett antagande om att dödsbränder är Poisson-fördelade, därmed betraktas antalet dödsbränder över tid som en Poisson-proceThe authors of this thesis were tasked with modelling fatal fires in Sweden to answer the question, whether the quarterly number of fires has changed over time. The usage of the Poisson distribution in modelling accidents and mortalities is well attested. Problems arise when measuring the number of fire related mortalities, as several deaths can be attributed to one fire. This violates the assumpt
The goals of this project are to investigate the viability of using the MyoTM armband developed by Thalmic labs as a tool for myoelectric control of a hand prosthesis as well as investigate whether the armbands ability to record its spatial position and orientation can be used to increase the performance of the prosthesis control program. Using the surface electrodes, gyroscopes and accelerometers
Lies are part of everyday life, but lies within the justice system is illegal (perjury). Yet it happens that people are committing perjury, increasingly, with potentially serious consequences. Statistics from 1976 – 2009 show that more than half of all who are found guilty of perjury is between 15 and 20 years and that the number of women is a growing group. It can be read from eighteen legal case
Background: The People’s Republic of China is one of the world’s largest countries, whose approximately 1.3 billion citizens make it the most populous nation state on Earth. It is also one of the world’s most powerful and booming economies, and biggest polluters. As such, the PRC’s actions aimed at continuing industrialization and urbanisation play a key role for future ecological development all
Populärvetenskaplig sammanfattning: Naturens tandemcykel – på väg att spåra ur. På senare år har det talats allt mer om klimatet och allt som ses som ett hot mot det. För växter och djur spelar de säsongsmässiga variationerna i miljöförutsättningar roll för när på året olika steg i deras utveckling sker, hur deras fenologi påverkas. I denna uppsats studeras några av de resultat av förändrad fenoloPhenology, the yearly development cycles of plants and animals, driven by seasonal changes in temperature and other environmental prerequisets, have been studied for hundreds of years. During recent years, with the ongoing changes in climate scientists have seen on earth, the interest for the research results from phenology studies has increased from several angles. It is no longer just ecologists
Our interest for this subject was awakened by the complexity with teachers having to report their students for being physically or psychically abused or neglected at home. Our aim in this study has been to discover junior school teachers’ idea on the mandatory reporting law between schools and social services in Sweden. Due to this purpose, interviews have been made with six junior school teachers
The adhesive properties in packaging material have been simplified for a long time. As more advanced packages are developed the correct mechanical properties for the adhesive strength is needed to make packages cost efficient and reliable. The problem today is that no good evaluation technics have been developed for determining the mechanical properties of adhesives. Different test methods for de
Sammanfattning: Många verksamheter använder karttjänster för att lösa problem och underlätta beslutsfattande. Allt fler upptäcker fördelarna med detta och integrerar karttjänster i verksamhetssystem. Dessa tjänster utvecklas från grundläggande karttjänster som kan ha betydande skillnader mellan sig vilket gör valet av tjänst till en viktig fråga. Eftersom karttjänsterna är olika och uppbyggda av eSummary: Many organizations use map services in their daily work to solve problems and enhance decision making processes. The number of organizations who enjoy the benefits of map services and integrate them into their system is increasing. To choose a certain map service is an important decision since the differences between them can be significant. The service is dependent on many minor componen
The purpose of this study was to explore medically trained care givers’ views on their work with people with dementia, focusing on their professional discretion and the standardized tools they use in their daily work. The aim was to gain a deeper understanding of aspects of their work that overlap with social work. The method used was qualitative semi-structured interviews with six caregivers, wor
Augmented reality is a field which is getting increased funding every year, as more businesses are realizing the potential of rendering virtual objects in the real world. As the equipment gets more commercialized, the costs will get lowered while performance also goes up. As of now, augmented reality mostly makes use of plane detection and marker detection to find and locate objects. We want to in
