In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

The competition in sports equipment and sports fashion today is fierce. And as e-commerce grows, the competing players has to remain accessible and usable regard-less of the device their customers visit the website on. Stadium is Swedens biggest player on the market and puts a lot of effort on their online activity. Something Stadium found interesting was the possibility of introducing elements that would increase the conversion rates directly into the product menu. This study explores the possibility to find a responsive solution for the product menu at Stadiums? e-commerce website which could contribute to increased conversion rates.The study is built upon an experiment and the foundations of the experiment is based upon a market analysis of used design patterns for product navigation in the domain of sport resellers.

This is a report for our thesis that was conducted as a conclusion of our bachelor degree in Business engineering at the Royal Institute of Technology (KTH). The work is done in cooperation with the firm Navigate Consulting Business Solutions AB.They have their leading expertise in Oracle E-Business Suite and has previously chosen to implement Oracle EBS R12. The modules that are planned to be implemented are general ledger (GL), accounts payable (AP), accounts receivable (AR), project module (PA), purchases, and CRM. For a consulting company like Navigate, it is particularly important to have a simple and effective time reporting process. We were therefore asked to provide new tabs with a decision-making process to determine if Oracle Time & Labor (OTL) is a useful time tracking system for their business.In order to achieve the company´s aim and objective we decided to follow a development method with five different phases.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

This Master?s thesis is about the public library development in a rural district, in this case Bergunda, a large rural district in Kronoberg?s County in Småland in Sweden, existing 1952 ? 1970. The main question is; how the public library develops in Bergunda large rural district 1951-1970. The main question is divided up in sub-questions: the district uniting in 1952 and 1971; personnel; lending; library housing and the public library structure. In 1952, there is one public library, Bergunda public library, and four study circle libraries.

The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Denna undersökning syftade till att undersöka om Larson m.fl. (2012) teori om kantiga och runda former kan appliceras på silhuetter i ett ovanifrånperspektiv, samt om de kan förmedla hotande eller lättsammare intryck för betraktaren. Kan betraktaren uppfatta vilken roll karaktären är ämnad att inneha inom ett MOBA-spel och blir någon av rollerna lättare eller svårare att avläsa när dess geometri förändras? För att ge bakgrund till undersökningen går arbetet igenom tidigare arbeten och undersökningar inom geometriska former, silhuett, analys med ikonografi, strategispel och karaktärsdesign. Som artefakt till undersökningen skapades tre olika karaktärskoncept som behandlar klasserna Carry, Support och Tank.

Typically, when Faurecia in Torsås are planning a new assembly line, one of the steps is to build a full-scale model of the line in card board, a form of mock-up planning. Faurecia has shown interest in finding an alternative methodology. The purpose was to explore the possibility of replacing today's cardboard based mock-up planning with models in a digital simulation environment.The purpose of the thesis has been to answer some of these complex questions; What are the benefits of using a simulation tool? In what way can we use it? If we choose to use a simulation tool, in what way does it affect our way of planning an assembly line? What are the advantages and disadvantages? Are there any economical and social aspects?Our results made us realize that a digital simulation tool does not replace the card board. On the other hand simulation could be used as a complement.

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.
