The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

This Bachelors exam is about young adults and their use of Mobile Social Network System.The use of mobile social media has become more common in today?s society, ranging fromteenagers, the dominating internet users, to the elderly. The traditional purpose of use inmobile phones, the voice communication from one place to another, has in Sweden beendominated by text communication instead. Along with the development of Smartphones andthe mobile interface, the births of mobile social media have increased in the market.Reports have shown that of all the devices with the possibility to connect to social networks,the one kept closest to our bodies is the mobile phone. One of the advantages of using thephone for mobile social media is that you can easily and smoothly update whenever andwherever, within one arm?s reach.

Usability is a well-known term in system development. Today both consumers and organizations aim to increase usability. The purpose of the study is to gain knowledge about inexperienced users? interactions with websites and concretize that knowledge for future studies.Interviews have been conducted within two areas where experienced web developers with extensive programming knowledge brought know-how while inexperienced users without any programming knowledge have given their views. A number of existing tools for web publishing have been analyzed.

SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.

This thesis have been performed at Sweco Position in Jönköping. The work was split into two, where one part included an investigation regarding the possibility of developing a cross-platform GIS (geographic information system) with HTML5 and CSS3. A prototype would also be developed within this part.The second part included development of a cross-platform GIS for a client to Sweco Position. The client operates in the forest sector and had already an existing solution, with many problems. The client required an application with delimited functionality and which was not bound to a specific hardware.As the client users often were located in areas with limited Internet access, one additional requirement was that there would be some offline support.The students handle subjects within development of GIS, for example map projections, map services and mapping libraries.The application came to be developed in HTML5 and ASP.net.

This report is an examination paper in computer science at University of Växjö. The report will focus on the possibility to create adaptable systems and to cost calculate the work needed to modify a system to meet new demands. A project [demos] developed by Interactive Institute studio [12-21] in Växjö is the starting point in our work. They have during a period of two years developed a prototype of a system which intends to get youth and democratic selected representatives a communication platform where they may communicate with SMS. Today they are in a position when they want to develop the system for other user groups with slighter different purpose and to do that they need a more flexible system.

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

The aim of the present study is to describe the experiences of high school students as regards the effects of their activities, in and out of lessons, being published on the web. In addition, a further purpose is to acquire knowledge about whether a website could be used as means of increasing the students level of attention, and focus, to their activities in school; and, furthermore, how such a website should be designed to correspond with the students requests.The implemented methods are interviews with students, school administrators and teachers. A survey was conducted covering the student?s personal experiences and opinions. Furthermore, an interface test of the website was performed.

A zoonosis is a disease or infection that is naturally transmitted between vertebrate animals and humans. The majority of infectious diseases that affect humans are zoonoses. Environments where wild animals, domestic animals and humans live in close proximity with no or small boundaries in the ecological system favor the transmission of diseases between animals and humans. The above described situation is more common in low income countries, where humans and animals live in high density and zoonoses are generally more common. The study was conducted in Cambodia.

This thesis is based on an assignment from a unit within an international group manufacturing industrial products. The purpose of the thesis is to analyze and suggest ways to improve the cost accounting system in use at the unit. The main source of empirical data has been interviews with employees. The theoretical framework is based on a comparison between traditional/standard costing and activity-based costing (ABC). The cost accounting system in use is described in detail and classified as a traditional/standard cost accounting system.

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

The smartphone is part of our daily life. Smartphone users type on a screen area that is no larger than the palm of a hand. To help with this endeavor the software known as AutoCorrect was created. However little is known about how AutoCorrect actually change the language and if AutoCorrect users at all perceive the impact it has. This study aims to find out if our test subjects are aware of AutoCorrect?s presence and how much it influences them.
