Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.

The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

When an error occurs in an IT system that is vital for the production of a major industry, the consequences can be great. To quickly identify and correct errors is important as a stop in a system can lead to a break in production, which is costly for the industry. Our task in this thesis has been to develop a system for ÅF that facilitates the debugging process of the system Paperline. The system's target audience is ÅF-call personnel that provides support for Paperline 24 hours a day if something goes wrong. The system consists of a Windows service, a database and a web application and is developed mainly with the techniques C#.NET, MVC 5, Google Charts, Javascript, HTML, CSS, and Entity Framework.

Arbetet undersöker grafikkortets lämplighet att tolka L-system i realtid. L-system är ett strängomskrivningssystem som beskriver strukturen hos botaniska former. Lsystem tolkas med hjälp av sköldpaddstolkningen för att få en geometrisk tolkning. För att utvärdera om grafikkortet är lämpat att tolka L-system i realtid har två system implementerats. Det ena systemet tolkar L-system på processorn och det andra systemet tolkar L-system på grafikkortet.

This study is one of five that has been done based on Lunds Energi?s planned investment in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be supplied with biofuels. In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage sludge.

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders.

När man lever i ett samhälle där användandet av mobila enheter som smartphones ökar, sker motsvarande ökning av frågan på tillgång till befintliga system i mobila enheter. Ett mobilt system kan utvecklas på olika sätt beroende på efterfrågan och kunskapsbasen hos utvecklarna. Det finns olika sorters mobila system, däribland webbaserade och plattformsspecifika system.Den här rapporten innehåller en förstudie för olika tillvägagångssätt för att skapa en mobil version av ett system. Rapporten redogör för olika tekniker som kan användas beroende på vilket system som önskas överföras, samt vilken målgruppen är. Rapporten beskriver också hur framtagandet av ett mobilt system för olika mobila plattformar har skett för ett redan befintligt system..

This thesis examines if commercial-of-the-shelf (COTS) systems meet the needs in different types of organizations. This was investigated through a case study of a COTS system. The system is built for contact centers and used in different types of organizations. Contextual inquiries with users from six different organizations were held together with interviews with stakeholders of the system. This gave an understanding for how the system is used and the needs to be met in the different organizations were recognized.

The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.
