The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.
Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.

Analys av sorptiv kylning i industri- och kontorsbyggnader
Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.
Energieffektivisering i flerbostadshus : En analys av ägarformens påverkan på arbetsprocessoch resultat
In Sweden the residential and commercial sector is a major user of energy, why the Swedish government has set a specific goal to half the energy usage in buildings by 2050, compared to 1995. The Swedish Energy Agency has therefore started the campaign ?Halvera Mera? to encourage demonstration projects that will show how to renovate in an energy Efficient way, and in doing so prove that it is possible to reduce a building?s energy usage by half and still make a profit. These projects are intended to serve as good examples and give inspiration to residential owners to perform energy Efficient renovations. To make sure that these projects serve their purpose, it is important to know what will inspire and what will impede a residential owner to invest in energy efficiency improvements.

This will provide insight and contribute to the debate on Efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.
Energieffektivisering av två flerbostadshus i Västerås, byggda 1963 : Enerigbehovsberäkning med programmet VIP+
AbstractThe background for this study is that there were a great amount of buildings constructed in Sweden in the years 1965-1975 in a program designed to create one million apartments in a time-period of ten years. These buildings are now, somewhat forty years later in most cases in very poor condition and the need for renovation is great and urgent. This has become a growing problem and more and more voices are being heard pointing towards the vast and extremely expensive task of renovating these buildings. Lately, it has also been more and more important for buildings to be energy-Efficient and sustainable environment friendly.In recent years there has been an atempt to solve these problems by renovating such buildings but at the same time making them very energy-Efficient. This is in some cases being done by isolating the shell of the building and changing the ventilation-system and so forth.

End of line test : En studie av företaget Emotrons linjetestning i produktionen
Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more Efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.
Att mäta eller inte mäta? : En kvalitativ undersökning om prestationsmätningar på en av Blekingesjukhusets kliniker
Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the
government now requires that hospitals will no longer be running a deficit.
Blekinge Hospital will then use their limited resources to survive in the
future and the activity must be enhanced in order to keep costs low without
having to lay off personnel. The idea is that the organisation should be more
Efficient with a more Efficient resource usage.
Performance measurement systems are important tools for achieving the policies
