Parametriserad 3D-modell av cyklon : Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

Grammatiken bakom den politiska retoriken : En syntaxstudie av före detta statssekreterare Lars Danielssons uttalanden angående sitt ansvar i regeringens hantering av tsunamikatastrofen 2004

In this thesis I based on Fowler?s method of syntax analysis construct a flow scheme which I then use to make a syntax analysis of former State Secretary Lars Danielsson?s statements, in his autobiography, regarding his responsibility in the Swedish government?s management of the 2004 Indian Ocean tsunami disaster. The focus of the flow scheme is how grammatical constructions can be used in the interest of rhetoric?s to on the syntax (non-explicit) level of the text indicate and place responsibility with or outside of involved individuals. The main conclusion of the syntax analysis performed is that Danielsson in his autobiography in fact does not use very many of the constructions described in the flow scheme, whereby it can be concluded that the syntax analysis in this case wasn?t so ?revealing?.

Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

I en värld av makroekonomisk osäkerhet - En scenarioanalys kring ränte- och inflationsförändringars inverkan på ett fastighetsbolags fria kassaflöde

Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.

Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Afghanistans demokratiseringsprocess : En kvalitativ fallstudie om förutsättningarna för att lyckas med konsociationell demokrati i ett av världens fattigaste länder.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

Headhunting : Rätt "man" på rätt plats?

Syftet med denna studie var att undersöka unga idrottares upplevelser i en topprestation.Studiens frågeställningar var:·        Vilka upplevelser har unga idrottare i en topprestation?·        Upplever unga idrottare flow i en topprestation?·        Vilka faktorer ligger bakom en topprestation hos unga idrottare? Utifrån syfte och frågeställningar valdes mätinstrumentet Flow State Scale-2 (FSS-2).

Kategorisering av faktorer som påverkar flödeseffektivitet - En fallstudie på Capio St Görans Sjukhus

Swedish healthcare is in continuous need of cost savings and efficiency improvements in order to meet the increased demand for care. The theories of lean, developed from the industry, are applied more frequently on healthcare systems to increase effectiveness and reduce waiting times in patient processes. However, some processes seem to be more successful in their lean implementation than others. In this thesis, factors influencing flow efficiency in lean healthcare are examined. Through interviews with the top executive board at Capio St Göran's hospital, data is collected in order to analyze reasons for success.

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Det implicita avkastningskravet på Stockholmsbörsen: En jämförande empirisk studie med avseende på antalet börsintroduktioner för 1999 och 2012

This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

Vilka faktorer påverkar företags kassahållning?: En studie av svenska börsbolag 1999 - 2009

This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.
