Modellering av en panna med rörlig rost :
The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
Bärförmågetillväxt i pålad friktionsjord
Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.
PIOTROSKIS FUNDAMENTALA SIGNALER;ÄR DE VÄRDERELEVANTA? : EN NUTIDA STUDIE PÅ STOCKHOLMSBÖRSEN
This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.
"Din gud är fejk, dra åt helvete!" : Om elevers syn på religionskunskapsämnet och dess inverkan på förståelse och tolerans
This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.
Kan en heterosexuell man ha feministiskt sex? En studie av villkoren för mänskligt handlande.
SammanfattningSyftet med denna uppsats är att söka svar på vilka analytiska verktyg som krävs för att förstå villkoren för mänskligt handlande. Min tes är att den diskursteoretiska epistemologi som kommit att dominera samtida feministisk forskning - i uppsatsen representerad främst av Judith Butler - inte tillhandahåller dessa analytiska verktyg. För att pröva denna tes har jag intervjuat fem heterosexuella, feministiska män om deras erfarenheter av sex. Jag frågar mig: på vilket sätt bestäms intervjupersonernas sexuella interaktion med kvinnor av deras respektive positioner som heterosexuella män och som feminister? I min analys tillämpar jag ett dialektiskt angreppssätt och stöder mig framför allt på Margaret Archers teoribygge.Min slutsats blir att det, för att i detalj kunna blottlägga villkoren för männens handlande, är fundamentalt att göra den typ av distinktioner som diskursteorin emotsätter sig - mellan subjektivt och objektivt, diskurs och praktik, etcetera.
TOM effekten i Sverige: En studie rörande överavkastning kring månadsskiften på den svenska börsen
The purpose of this paper is to study whether or not stock returns increase abnormally over month ends on the Swedish stock exchange. Previous research has proven an international so called ?Turn-of-the-Month? effect where stock returns increase significantly over a few days around month ends. If the effect exists, it is a violation of Fama?s Efficient Market Hypothesis.
Spelar det någon roll om du heter Linnéa eller Amina? : Om namnets betydelse i rekryteringsprocessen.
The purpose of this study was to examine how students of the Human Resources and Labour Relations Programme evaluates work applications from Swedish and Somali women. 55 students participated in the study. The respondents were supposed to read a fictitious work and from that, judge four applications from four women where two had Swedish names and two had Somali names. The independent variables were the participants' gender, grade and university (between subject variables) as well as the applicant's name (Swedish vs. Somali) as the within-subject variable.
Idiopatisk epilepsi hos hund
ABSTRACT
Epilepsy describes a neurologically caused condition which involves seizures. Epilepsy can be classified according to different types of causes and the nature of seizures can vary. Medication for epilepsy in dogs is limited in comparison with human medicine.
Idiopathic epilepsy is the most common neurological disease and one of the most common genetic diseases in dogs. Because epilepsy has a higher prevalence in certain breeds, there is reason to suspect that it is a hereditary disease.
The inheritance of idiopathic epilepsy is for most breeds not determined, except for a few variants of the disease.
Regler i förskolan : En studie om förskollärares och barns tankar
This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.
Aktiva ägares påverkan på svenska börsbolags lönsamhet
This thesis investigates the effects of active ownership on the return on assets (ROA) of Swedish listed companies during the years 2003 to 2013. Active ownership is operationalized based on the probabilistic voting model that is used to calculate the minimum amount of shares the largest shareholder needs in order to possess control of a contested vote at the shareholder meeting. We study the three largest lists on the Nasdaq OMX Stockholm, having 1454 observations from 207 companies to test our hypothesis. The main result from the study is that there's a significant positive relationship between active ownership and ROA during the investigated period. The active owners' relative strength also proves to have a significant positive relationship to ROA..
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Multipel regressionsanalys av variabler som paverkar BNP
In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.
Finlandsmodellen Konsekvenser av ett införande ? ett lantmätarperspektiv
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..
Värderelevansen av Bokföringsdata - samband mellan immateriella tillgångar och marknadsvärde
In latter years there has been a discussion about the increasing importance of intangible assets and how to incorporate this fact into strategies, accounting and valuation. The ?Internet-bubble? is a recent event that drew much attention to intangible assets, and was an indicator of how complex it can be to value assets in general and intangible information in particular. Legislators recently addressed this issue by introducing IFRS3, which led to an update of IAS38, which in turn revised the methods for handling intangible assets. A specific intangible asset that has caused much debate is research and development (R&D), since it is commonly not allowed to be realized as an asset, which could cause implications concerning analysis and valuation.
