Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer
Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.
Vilka faktorer bidrar till att spelare fastnar i MMORPG spel?
Massiva onlinerollspel är idag mycket populära och försäljningen och spelandet utav dessa ökar markant. I och med detta väcks frågan om vad det är i dessa onlinespel som gör att människor spelar och fortsätter spela. Denna uppsats inriktas främst mot MMORPG:s, Massively Multiplayer Online Role-Playing Games, då författarna anser att det är i denna onlinespelsgenre den största möjligheten att finna och definiera de faktorer, som påverkarspelares vilja att spela, finns. För att ta reda på dessa faktorer skapades en enkät vars frågor utformades med en gameflowmodell i baktanken. Denna enkät lades sedan ut på sex olika onlinespelsanknutna forum, där totalt 105 spelare anonymt deltog.
Biblioteksutvecklingen i Karlsborg 1907-1970 ? vägen mot ett kommunalt folkbibliotek
The purpose of this master thesis is to describe and analyse the development of the library history in the municipality of Karlsborg. This is done with a comparison to the library development in Sweden as a whole and in particular to the cities of Lidköping and Halmstad. I have worked according to the following questions: 1. How did the libraries develop before the municipality took over? 2.
Österåkers folkbiblioteksutveckling under åren 1958 ? 1983
The purpose of this thesis is to describe and analyse the development of the public library in the district of Österåker during a period of 1958-1983. The main goals have been to identify the crucial events in the history of the library within their historical context and to analyse the factors that have been important for the development: financing, location, staffing, stock of books, book-lending level and different activities for children, youngsters and adults. The consideration has been taken to reasons and consequences of these events. The hermeneutic interpretation model of interaction between parts and wholes, between reasons and results is the basic method in this research which leans mainly upon local archives in Österåker. The public library in Österåker was established in 1952 as a fusion of previously existing small libraries: the parish library in Östra Ryd, the Labour Movement?s library and the temperance movement?s library.
?Det sade bara klick?: en studie om 15-åriga tjejers Internetanvändning utifrån ett källkritiskt perspektiv
This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.
Re-design av BEV-heater
Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.
Produkthantering vid tillverkning av roterande verktyg
AB Sandvik Cormorant?s production unit in Gimo has identified a need to examinethe handling of products between operations with the purpose of generatingproposals of improvement for the product handling.The aim of this project is to study the existing manufacturing process and givesuggestions for improvement. The proposals should reduce the manual handling ofproducts, decrease the risk of damaging the products during the manufacturing andform a basis for increased traceability. Based on a mapping of the manufacturingprocess and the problem description, a specification of requirements has beencomposed.The mapping of the manufacturing process suggests that a change of the currentsystem is required. The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.
Kapitalstrukturens inverkan på företagsvärdet : - En kvantitativ studie av den svenska aktiemarknaden
Background: During extreme market conditions like the period during fall 2008 the discussion of what affects company value becomes apparent. The capital structure is the relation between borrowed capital and equity in a company´s financing mix. What impact changes in capital structure have on company value is a widely debated subject within the theory of finance. If a relationship between capital structure and company value exists the implication is that an optimal capital structure where company value is maximized also exists.Aim: The aim of the thesis is to study whether a certain relationship between capital structure and company value exists among selected stocks and companies listed on Stockholmsbörsens OMXS30.Implementation: With aim to fulfill the purpose of the thesis regression analysis has been performed among chosen stocks and companies. The empirical results eventuating from this have been analyzed from the view of elected relevant theory.Completion and results: We find that during normal market conditions a positive relationship between debt ratio and enterprise value (EV) can be established.
Panic - IT-stress och Design med hälsa i tanken
Från början hade vi ställt in oss på att vi ville hitta ett nytt sätt på hur man kan designa IT-relaterade produkter med ungdomars välmående och hälsa i tanke. Detta visade sig inte vara den lättaste uppgift två interaktionsdesigners, utan någon som helst bakgrund eller insyn om människors välmående, kunde tänka sig. Efter mycket efterforskning både i böcker och på Internet började vi förstå att vi inte var ensamma i vårt mål att motverka att stress uppstår i relation till dagens informations teknik. Flera andra forskare med bakgrund inom sjukdomar, rehabilitering och medicin hade varit aktiva inom fältet men bara ett fåtal interaktionsdesigners innan oss hade försökt sig på något liknande. Vi fick mycket inspiration från deras tidigare projekt och vi har försökt använda oss utav deras kunskaper och resultat.
Investeringskalkyl för en ny såglinje : en rapport om investeringskalkylering
This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge.
In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change.
The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes.
The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.
Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter
The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.
Värdepapperisering av samhällsfastigheters hyresflöden : En attraktiv finansierings- och investeringsmöjlighet för att bygga vård- och äldreboenden till en åldrande befolkning?
The number of elderly people has been steadily rising in Sweden for a long time and as a proportion of the population, the increase has been even greater. The population structure in the country means that in the not too distant future, there will be a sharp rise in demand for care and elderly accommodation.A tighter credit market as a consequence of new rules and regulations with a stricter capital and liquidity requirements combined with market turbulence, has made financing property developement more difficult and more expensive which has resulted in many companies using alternative sources of finance.DEmand for safe investments with low risk is high as the market is volatile and banks, pension funds, fund management and life insurance companies are looking for investments outside the stock market that can deliver a safe return in the longer term. There has also been a debate about whether institutional investors as the AP pension funds really should own properties directly.As properties for care and elderly accommodation are definable assets with predictable payment flows, long leases and often a local authority as tenant that would not risk cancelling payments, these would be highly appropriate for securitisation, i.e. to issue bonds or other tradable securities based on the cash flows from the assets.In other words, the securitisation of rent flows would offer the opportunity to create an attractive investment product of the type being demanded, well suited to institutional investor requirements, while at the same time, it can provide an attractive financing opportunity to meet the need for more care and elderly accommodation..
Har IFRS gjort redovisningen mer effektiv för investerare? En studie om goodwillpostens relevans. : En studie om goodwillpostens relevans.
Title: Have IFRS made the accounting more efficient for investors? ? A study of goodwill-relevance Level: Final assignment for Degree of Master (One Year)Author: Patrik Nygard and Andreas Pettersson Supervisor: Markku Penttinen Date: 2010 ? MayAim: The Swedish banks SEB and Swedbank are on the same market but their goodwill is amortized totally differently and its results will be different. We decided to examine the accounts in Sweden and see if they have been more efficient, from a user perspective, after the introduction of IFRS in year 2005Method: This paper is made from a quantitative and a deductive approach. We have collected data from all companies listed on the Stockholm Stock Exchange between the years 2002-2008 using the computer program Financial Datastream and then made the regression and other analyses and comparisons with the program MinitabResult & Conclusions: We have in this paper demonstrated that how the accounting of goodwill designed is relevant to investors and that this relevance has increased in Sweden after the transition to IFRS. We have also concluded that the goodwill has greater relevance in a rising market than in a downward.Suggestions for future research: In future researches can the aim be to compare other accounting standards changes that occurred in the year 2005 and see if the accounting, from that perspective been more efficient.Contribution of the thesis: We have shown how the account influences investor?s decisions during different accounting systems and in particular how they react on the changed account of goodwill.
Kvantifiering av osäkerheter i lyftkraftsmodellen
With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.
Studie av flöden på en dagkirurgisk avdelning
Sepsis (blodförgiftning) är ett allvarligt tillstånd och behöver en snabb diagnos som fastställs genom blodprov. Blodprov från hela Stockholms Län skickas till Karolinska Universitetslaboratoriet (KUL) för analys, där biomedicinska analytiker och läkare fastställer arten på infektionen och beslutar vilken antibiotikabehandling är optimal.Målet med arbetet var att identifiera eventuella problem som skapar flaskhalsar hos Klinisk Mikrobiologi i Solna som är en del av KUL. Därefter skulle lösningsförslag framföras och möjligheten att införa blodprover i ett nytt automatiskt system, BD Kiestra Total Lab Automation undersökas.Verksamhetskedjan för laboratoriet analyserades genom observationer och läsning av metodbeskrivningar. Utifrån verksamhetsanalysen identifierades sedan problem. En utbildning med BD Kiestra TLA gav en översikt av hur systemet fungerar samt fördelarna med att använda det.Genom litteraturstudier samt öppna intervjuer kunde förslag på lösningar och förbättringar framföras. Resultaten behandlar de lösningsförslagen för de identifierade problemen, och sammanfattas i en tabell. BD Kiestra TLA behandlades separat med en systembeskrivning, följt av de problem som finns för införandet av blodprov och hur dessa problem kan lösas..
