While many industrial processes have been thoroughly exposed to machine learning models, the realm of powder metallurgy is still underexplored. This thesis aims to investigate the potential for a machine learning model to predict the characteristics of metal powders after a reduction annealing process using time series process data from the furnace. A supervised learning model was developed to pre
In this thesis, we investigate the water-wave problem for two-dimensional steady waves with constant vorticity. We introduce a new approximate model that, in its simplest form, reduces to a planar dynamical system. We then analyze this system for various energy levels and vorticity constants, studying its phase portraits to determine the locations and types of solutions that arise. In the unidire
Three standard approaches of finding Value at Risk; age weighted historical simulation, volatility weighted historical simulation and t – distribution were compared with Value –at – Risk calculated using generalized extreme value theory during the period 2000 to 2010 to see which approach that would give the most accurate forecast of actual losses during the two volatile times within the time fram
UNICEF reports and daily newspaper reports suggest that street children are excluded from existing child rights facilities in Bangladesh. To examine the situation of social exclusion of street children, this paper examined the development policies for children in Bangladesh to understand how the existing policies can protect street children‟s rights and how they could enjoy country‟s currently ava
The purpose of this report is to develop a model that identifies and reveals the total carbon dioxide emissions generated throughout in- and outbound freight transport made by Höganäs Sweden. The developed model is to be used for future environmental calculations and also act as a tool for discovering new areas of environmental improvements. During the developing process of the model a key issue
This bachelor thesis describes the evaluation of a new software for deconvolution of liquid chromatography diode array detection (LC-DAD). The principal component analysis (PCA) based algorithm, Archimedes, is under development and there are still some issues that need to be resolved. However, the results are encouraging and potentially this algorithm will significantly extend and improve the appl
In 1991 the African Union established a plan for creating a monetary union for the whole continent. The plan, the Abuja Treaty, aim to unify the continent, creating stability and improving economic welfare. Several regional economic communities (RECs) are the foundation of this plan which means that the progress is primary dependent on their successful development. This essay studies Africa’s prog
The Fire Risk Index Method is a tool for assessing fire safety in multi-storey apartment buildings. This report contains a description of how Version 1.2 of the Fire Risk Index Method was developed. The terminology frequently used in the development process of the method is also explained. The use of the Fire Risk Index Method is described and illustrated by an example. The method is applied to an
RNA interference (RNAi) has recently been discovered in the budding yeast Saccharomyces castellii. As in other organisms, artificial RNAi could be a useful genetic tool in budding yeast, but the method needs first to be established. S. castellii is also a useful model for telomerase studies, and a knockdown of the telomerase catalytic subunit Est2p could be a new way of unrevealing its functions a
This thesis addresses many issues surrounding the simple question: why have trams? With city populations exponentially growing alongside concerns over the environment and the economy, tramways have become a resurging form of sustainable transportation for municipalities. Once an endangered transportation mode, torn up and scrapped to make room for the age of cars, tramways are phoenix artifacts of
A need for autonomous electro-mechanical machines performing tasks that can save human efforts and even be deployed in hazardous environments along with the research in the field of human mind and body has led to new fields often called AI Robotics. To provide a mean for stimulating students and researchers around the world for promotion of this new field, an annual world championship, Robocup, ha
Rapporten är en sammanställning av ett kandidatarbete, huvudsakligen utförd som en ”Minor Field Study” i Kumasi, Ghana och i samarbete med WASHCost. WASHCost är ett pågående internationellt forskningsprojekt med holländska IRC som initiativtagare. Genom att använda data, insamlad av forskare från WASHCost i Ghana har jag undersökt vilka kostnadsdrivare som kan användas för att förutsäga kostnadernUsing data gathered by researchers from WASHCost project in Ghana, this thesis examines how cost drivers can be used to predict capital expenditure for construction of piped water systems for small towns in Ghana. The data is collected from 45 small towns and communities in peri-urban areas in the Volta, Ashanti and Northern region. I have used correlation analysis and multiple regression analysis
The purpose of this thesis is to enable for a qualified estimation of delivery schedules for future construction projects by developing a computer program
Etableringsfriheten för företag är en av de mest fundamentala rättigheterna i Lissabonfördraget. Fördragets artiklar utgör grunden för rättigheten och ger företag rätt att starta eller driva verksamhet i vilken medlemsstat som helst i EU utan att diskrimineras. Denna rättighet har ytterligare utökats genom införandet av nya företagsformer och genom harmonisering av bolagsrätten i ett flertal direkThe freedom of establishment for companies is one of the fundamental rights enshrined in the FEU Treaty. The provisions of the Treaty set out the basis for the right and give companies the freedom to take up and pursue activities in any Member State of the EU without being discriminated. This right has been further expanded through the adoption of new company forms as well as harmonised through se
In this study, opportunities for utilizing biogas produced from anaerobic digestion of different organic wastes as a vehicle fuel in South Korea have been investigated, using experiences from Sweden as a basis for analysis. Strategic governmental policies and financial support have enabled many municipalities in Sweden to successfully develop biogas/biomethane as a locally produced renewable fuel.
Populärvetenskaplig sammanfattning I dagens samhälle används diverse katalysatorer i många sammanhang för att påskynda kemiska reaktioner. Allt från produktion av ammoniak till rening av avgaser hjälps av olika katalysatorer. De katalysatorer som vi känner idag har tagits fram genom att testa olika materialkombinationer och utvecklingen har börjat stagnera. Enzymerna i våra kroppar är naturliga kA new instrument for near ambient x-ray photoelectron spectroscopy investigations of surfaces has been installed at beamline I511 of the MAX-II electron storage ring at the MAX IV Laboratory. This high pressure x-ray photoelectron spectroscopy instrument is capable of surface chemistry investigations in near ambient pressures using x-ray photoelectron spectroscopy (XPS), a technique that tradition
