Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

This thesis work has been carried out at the consultant company Pöyry Sweden AB in Norrköping, whom performs the task for E.ON heating Sweden AB, Händelöverket in Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops hydrogen gas in contact with water.The work has aimed to produce different suggestions of methods and equipment that can be used for the objective. Mixing method and security issues were in centre while working with the suggestions.

We were assigned to do this master thesis by Husqvarna AB who at the time for this thesis just had implemented a new material and production planning system called Replenishment system. Husqvarna AB wanted us to examine the effects of their new planning system to see if it was profitable or not. Husqvarna AB had for a time considered their delivery and supplier service to bee their biggest problem and they wanted to solve this problem by improving the communication with all involved actors in the logistic chain, which they hoped would result in a better mix of products in their warehouses. The aim of this report was therefor to analyze eventual effects for Husqvarna AB when changing from a traditional material- and production planing system to a more information intensive one. The result of this report showed effects on decreasing administrational routines and improved flexibility and lead-times.

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant. By also documenting how much time we spent involving users we will show to which degree user involvement is effective. We found out that a couple of fast techniques could get very much result in the form of usability enhancing suggestions to the developers.

This report deals with the performance of a batch flow treatment of landfillleachate compared with a continuous flow system. The parameters in focus were total Kjeldahl nitrogen (TKN), BOD5 and COD. The pilot-scale experiment used eight barrels with a volume of 150 liters. Each barrel was constructed differently concerning its flow, its bed material grain size and its presence of plants or not. Four of the barrels worked in batch mode, thus four in continuous flow mode.

Car-commercials are something that many people come in contact with on a daily basis.This is a study on commercials for cars and is focusing on visual effects that are madein post-production. In this report we are trying to find out if and how visual effects incommercials for cars affect how the observer remembers them. The second subjects thatwe use in this report is popularity and we try to find out if and in that case how visualeffects affect the commercials for cars popularity. We also investigated how frequentlycommercials for cars are showed on TV and how the visual effects are in them, it givesa better foundation to the other parts.The methods we applied were interviews, quantitative and qualitative content analysisof car commercials and also observation analysis of the 6 swedish TV-channels thatshows commercials and have the most viewers, to get an idea how frequently thesecommercials are shown. The commercials that were applied in this paper was from late2011 to early 2012.

This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.

This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

Abstrakt                                                                                             Syftet med undersökningen var att belysa och jämföra förändringar som sker i den kommunala musikskoleverksamheten när den utsätts för konkurrens och finansiering via checksystem. Undersökningen begränsades till Nacka och Österåker, de kommuner där systemet använts längst. Genom intervjuer av kommuntjänstemän och musikskoleledare samt i en enkätstudie hos musikpedagogerna undersöktes vilka faktorer som lett till förändringar i verksamheten och hur dessa upplevdes, samt hur de olika parterna såg på den framtida kommunala musikskolan. Resultatet av undersökningen visade att det var checksystemets utformning och kommunens styrning som bidrog till förändringar i verksamheten. Nacka kommun och Österåkers kommun hade utformat olika checksystem som gav skilda konsekvenser för verksamheterna.

Författare: Malin Pettersson & Emma SundåkerTitel: ?Typiskt manlig? Då tänker jag på fotbollsspelare som sjunger nationalsången?: En studie om fyra manliga sångares berättelser om sång, självkänsla och maskulinitetTitle in English: ?Typically masculine? Then my thoughts go to football players singing the national anthem?: A study about four male singers and their stories about singing, selfesteem and masculinityBåde för män och kvinnor är det problematiskt att inkräkta på ett fält som domineras av det andra könet. Populärmusikforskning med genusperspektiv har ofta fokuserat på kvinnor som befinner sig i maskulina praktiker, vilket därmed gör oss nyfikna på det motsatta. Att som ung kille våga erkänna att man tycker om att sjunga kräver mod samt självkänsla och självförtroende eftersom han trotsar de traditionella könsrollerna. Vi vill undersöka hur de män som har sång som primärt instrument förhåller sig till att deras instrument kan associeras till femininitet.Syftet med uppsatsen är att undersöka hur manliga sångare beskriver sin röst och röstutveckling, samt hur de hanterar att de verkar inom en feminin praktik.Uppsatsen bygger på fyra manliga sångares skrivna levnadsberättelser och är skriven ur ett genusperspektiv med fokus på maskulinitet inom populärmusiken.

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

Jag undersöker hur den konstnärliga processen att arrangera inom popmusik påverkas när man som arrangör använder sig av elektroniska instrument, programmerade för att återskapa akustiska klanger, istället för de akustiska instrumenten som återskapats. I detta arbete redogör jag för en process i vilken jag skapade elektroniska emuleringar av en trumpet, en tenorsaxofon och en akustisk gitarr. Som bilaga till arbetet finns en CD med två poplåtar där klangerna används i arrangemanget samt ett flertal ljudexempel med de individuella klangerna..

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.
