Uppgradering av stabilitetsberäkningsprogrammet NYSTAB

This is a report founded on a project by Atlas Copco called NYSTAB.  The application Nystab is a calculation program that can calculate the stability of the rockdrill-rigs made by Atlas Copco. The original version of Nystab is stored in a database from 1997 and the code is made in an old version of Visual Basic. My assignment was to develop the application in to a newer programming environment and make it last better in the upcoming years. The software I decided to use to accomplish this project is C# .NET in Visual Studio and Microsoft Access 2010. All the code is written in C# with some insertions from ADO.NET which helped me to easier connect the code with the database.The coding part was split into two pieces; the first was to develop the application scale done with Windows Forms, the second was to write the code for calculations in the application.

Webbplatsen EUROPA: en utvärdering av söktjänsten

The purpose of this thesis is to evaluate the retrieval effectiveness on the European Unions official website EUROPA, depending on which language is used to formulate the search question. Our main concern were if you get access to the same information depending on which language is used to search information The European Union has so far eleven official languages, and with the forthcoming expansion with negotiations with thirteen new countries to affiliate to the union by May 1:st 2004, the official languages will be even more. We have made a comparison between Swedish and English, using 29 different topics from which we formulated 2x29 queries. The topics used were found at the Swedish Governments FAQ about the European Union, EUsvar. We wanted the topics to be as authentic as possible to avoid bias.

Prefabricerade Passivhus

European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.

How Venture Capitalists can use their Network in order to reduce the Information Asymmetries between themselves and the Venture Management Team

The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.

Träning av lexikal förmåga hos ett svensk-arabisktalande förskolebarn : Utredning och intensiv intervention av det svenska ordförrådet

Sweden has a growing proportion of children living in a multilingual environment. It is thus highly important that caretakers as well as professionals who meet these children have knowledge of multilingualism and its impact on language development. Also, an increase of referrals of multilingual children with suspected language impairment to speech and language pathology clinics is seen.The objective of this study was to investigate the linguistic ability in both Swedish and Arabic in a four year old child with suspected language impairment. A further aim was to implement an intensive intervention and evaluate the efficacy of it. Language testing in both languages showed that the boy?s greatest need was in the lexical domain.

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Mixtekniker

A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.

Ekonomin i Sala gruvby omkring 1500 till 1600 : en jämförande studie av myntfynd från Sala gruvby och kyrkfynd

The subject of this essay in archaeology is the economy at the mining village of Saladuringthe 16th and early 17th century. The silvermine in Sala was once the foremost producer of silver in Sweden, and the mine as well as the mining village had had a long and rich history. This history can be seen in historical documents as well as in archaeological findings. The lure of silver attracted many different people to the mining village. This in turn madetrade an important part of the mining village.

Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

Modulbyggd förskola - Framtiden?

In 1999 the childbearing increased, which in combination with the closure of a number ofpreschools led to the shortage and reduced capacity in available places for youngchildren. The lack of places in preschools has led us to try to find a solution to theproblem and in order to solve the problem we have interviewed personnel of preschoolsin Halmstad. The persons we met were asked to list advantages and disadvantages oftheir preschool and also to come up with innovative solutions and new ideas of how todevelop a satisfactory preschool. This was the basis for us when we drew our drawingsand our main objective was to find a new template for the development of pre-fabricatedpreschools.When drawing a new and modern preschool a number of considerations have to be made,first of all the main objective for the children is play and playtime, a second objective issound reduction and laws about sound reduction. Another consideration is how toconstruct the building and which method to be used, for instance should industrialtechniques be considered and pros and cons be listed.The main disappointment amongst the preschool personnel was that they had noinfluence in the planning stage of the new development of the preschool.

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.

Modern marknadsföring - filmproduktion

I contacted the production company Salmonfox in the hope that they would have any projects that they needed help with. It showed that Salmonfox just started up an old project that they needed to complete. They wanted my help to edit some trailers and one crowdfundingfilm for the short film called, Captain Sweden (Kapten Sverige). Salmonfox are hopefully going to use the different trailers and crowdfundingfilm to promote the short film and get help with the funding to make a feature. The project began with a pilot study in which I made a time plan and a requirements plan, where the different requirements were set.

Fallstudie: en analys av Kungens Kurva utifrån Huddinge kommuns vision för vidare utveckling av området

In this thesis, a case study of Kungens Kurva in Stockholm is made. The municipality of Huddinge has designated the area, which is an external shopping-center, as one of its key development areas in the future. The municipality has established a future vision for the area, which extends until 2030. The vision claims, inter alia, that Kungens Kurva along with Skärholmen will become a vibrant suburb. How well the values and aims of the vision are met in the current area situation is discussed in the case study by a number of analysis that carries out the existing structures and characters of the area.

Produktutveckling av koncept för isbanesystem

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Manligt och kvinnligt för barn: Könsroller i 1980- och 2000-talets svenska bilderböcker

The aim with this masters thesis is to investigate how gender is presented in Swedish picture books, in order to give librarians and other actors in the field knowledge about what kind of books they supply impressionable children with. I investigate if and how the changes concerning gender-equality in the Swedish society during the last 25 years are reflected in childrens literature, and compare how men and women are portrayed in four books from the early 1980s with four books from the 2000s. My study is delimited to three aspects of character formation, introduced by Maria Nikolajeva: description of psychology, actions and relations to other characters. It is carried through by consultation of Yvonne Hirdmans theory of how men and women are held apart and that the man in this relation constitutes the norm as well as Nikolajevas list of typical male and female characteristics. By reading and interpreting the chosen books, I analyse both text and pictures.
