I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

The aim of this thesis is to improve the control of urea injection at the combined power and heating plant Framtidens Gärstad (FTG). Tekniska Verken i Linköping AB is the owner of the plant.The FTG plant consists of a boiler where garbage combustion is done. From the combustion nitrogen oxides are emitted. These nitrogen oxides are hazardous to the environment. To reduce the nitrogen oxides, injection of urea into the boiler is used.

The harbour in Arvika is closed down and the industry that has been established in the area is now beeing wound up. A deepened comprehensive plan for the area is under progress in the municipality. The intentions are for instance that the harbour should be integrated with the city and that Arvika is facing a lake should be more apparent from the city center. The harbour should also contribute to a more attractive city. These intentions have hence been the starting point of my undergraduate theses, which has resulted in a proposal on how to develop the harbour. During the process I have analysed the city image, how the area is used today and the public places in the city centre.

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

This study focuses on the encounter between the academic librarian and the academic library user with a specific need for information. The aim of the study is to examine the process of mediation of information and to uncover any inherent problems or systemic inertia that may occur within that process.Special attention has been given to information-seeking behaviour in the digital age and the possibility of viewing information literacy as a meta-literacy. The difference between the surface web and the academic invis- ible web is also investigated. Empirical data was collected by the use of ethnographic fieldwork at the Karolin- ska Institutet University Library over a period of five weeks. The data is analysed using actor-network theory as a point of departure.

With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

In Örebro, the car traffic share does not tend to decrease. The crowdedness on some of the bus routes is high at times. Investigations show that the residents of Örebro want a city centre whose street environment is more restrictive of car traffic and better for pedestrians, cyclists and public transport. To decrease the car traffic share a rapid, convenient, clear, effective and environmental friendly public transport with high frequency and strong capacity in a short, direct and logical network is needed. A modern tramway fulfils these criteria.At first, this report describes factors that are important to take into consideration when planning a tramway.

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

Strömstad is a small city located on the Swedish west coast. Urbanization and development is acurrent issue for the municipally, as for many other in the current situation. The municipal housingcompany Strömstadsbyggen is one of the parties involved in the extensive development that mustbe implemented to meet the changes and developments which the issue holds.One area that is of interest in the discussion is Rådhusberget - this due to the existing infrastructureand unique qualities that the area holds. In order to achieve the best solutions possible for the area,Strömstadsbyggen wishes to listen to what the existing tenants at Rådhusberget thinks and feelsregarding the area and its future potential.This thesis has therefore been carried out in collaboration with Strömstadsbyggen and has beenaimed at identifying the current tenants' thoughts and opinions in the existing area of developmentand infill potential. The aim of this work was also to investigate how the tenants value their homeand local environment in its current state, and what their wishes are for the possible futuredevelopment of Rådhusberget.To achieve analyzable results concerning how the tenants perceive these aspects, an extensivesurvey have been carried out which were sent out to all tenants in the area.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

The aim of the study is to describe the state of the forest and changes in the Lindberg nature reserve. The study area is a nature reserve with an old coniferous forest, which has not been touched since 1950. The pines in the area have a very big diameter and are 150 ? 200 years old. The spruces are up to 150 years old.

The 1990s were one of the most profitable periods for European airline companies, mainly because of development of world economy and increasing globalisation trends. However, towards the end of the decade, a global economic downturn, high oil prices and new forms of competition turned the industry towards troubled times. The European air-travel industry had to face and accept the new airline business concept, called low-cost or no-frill airlines. In these conditions, traditional airlines had to rethink their strategies and question the old business model. As a response to the competition, European traditional full-service airlines formed alliances or networks to expand the route network and to increase efficiency.
