Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.

An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers? browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess.

The purpose of this essay is to examine one of Sweden's oldest motorways in cityenvironment. The researched section is motorway E20 east of Gothenburg. Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.

This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.

The result of this work is a plan for the development of an 1128 m2 elderly raised garden. The purpose has been to create an overall plan covering the long-term development of the garden. The work process has covered a description of the garden of today, review of requirements, analysis of the garden sections, design of a new plan as well as starting the construction of the new garden. The plan covers a time period of a couple of years to create the new garden since the construction work is carried out during spare time with small resources available. The planning must contain review of functions such as protection from insight, eating area and compost area. Also the esthetic expression must be planned. Colors, shapes, choice of material and plants together make up the esthetic expression. It is recommended to include anything you wish to create in the garden. In a raised garden one has to overcome the step to remove trees and shrubs and think different.

In 1998, 'the Naval Port of Karlskrona' was inscribed as a World Heritage Site by UNESCO and thus, it is equally protected as China?s Great Wall and the Pyramids of Egypt.The essay is a case study of Karlskrona, one of Sweden's most well planned cities, where famous urban planners and architects such as Erik Dahlberg and Nicodemus Tessin the Elder has been involved.Today, Karlskrona is a rather unknown small town in Sweden's outskirts, where population growth has been a problem. When Karlskrona was founded, in the late 17th century, Sweden was a major power. The Blekinge archipelago was in the middle of the Baltic dominion and Karlskrona represented a midpoint in the kingdom. Therefore, Karlskrona has a small town charm with the history and style of a cosmopolitan city.By initially studying how the town?s character of today is expressed, the history of Karlskrona is explored.

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

The purpose of this study is to understand the factors that are affecting students at the Technology and Electricity- and energy programs in their choice of studies and vocation. The study is a comparative case study and quantitative method has been used in the form of questionnaires. The result shows that students do not like to be affected by another person but believes that they themselves have made their choice. Interest turns out to be the biggest influence factor of choice for both students at the Technology and Electricity- and energy program. For Electricity- and energy students have also access to work had some impact.The parents' education level was higher for Technician students and their parents worked with occupations requiring university degrees.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

Communication during the process of Environmental Impact Assessment: Interviews concerning three infrastructure projects Environmental Impact Assessment (EIA) is a method to describe the possible impact of a planned project. The aim of such an assessment is to aid a sustainable development, by supplying a comprehensive basis for decision-making. Today there are many people working with EIA in different forms, representing both different interests within the community, as well as having different individual points of view. The proponent is responsible for the EIA, but it is of interest to study the relationship between the different participants who are involved in this process. The aim of this report is to study how the different disciplines involved have communicated with each other and amongst themselves, what characterises good communication, and if anything should be improved.

One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.

The purpose of this essay is to develop knowledge about how learning among employees is perceived to occur practically in a pre-school unit seen as a learning organization. From an employee perspective the intention was to gain an understanding of how they perceive the organization regarding employee learning in the workplace when it comes to in which contexts and what conditions that enable collaborative learning. Because learning organization is mostly a vision from a management perspective thereby it should in this case mostly be viewed as the context in which the employees work in.The essay is based on a qualitative research approach with eight semi-structured interviews. It was based on hermeneutics as method of analysis with the intention to gain an understanding of the employees' subjective perception. It is a case study on a selected pre-school unit in Stockholm.
