Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Konsumenters kunskap och uppfattning om nyckelhålsmärkta produkter
Syftet med studien är att klargöra om nyckelhålsmärkningen har betydelse för konsumentens uppfattning och val av produkt, samt belysa förekomsten av källkritiskt tänkande kring nyckelhålsmärkningen. Som metod tillämpades intervjuer på 50 respondenter. Studien indikerar att nyckelhålsmärkningen har en inverkan på både val av produkt samt den generella uppfattningen om hur hälsosam en produkt är. Studien visar även på en slående avsaknad av källkritik då konsumenter utvärderar nyckelhålsprodukter..
Att uppleva rum - ett utforskande projekt om rumslig gestaltning
This project in an in depth exploration about the basics of creating space in the form of an experimental investigation using my own perceptions as reference. Within a method, especially outlined for the project using descriptive words of opposites, my interpretation of the words has been formed into models of rooms. Four workshops with restrictions and rules acted as a platform for the striving towards the aim of a wider understanding of how space can be experienced. Through analysis I have formulated the different parameters influencing space itself and my perceptions of it. During the project a language for visualizing the interpretations of a room has been further evolved.
En energiutredning och miljöklassning av Hemsta 12:16
The purpose of this study was to implement an energy analysis and environmental evaluation of the property Hemsta 12:16 in Gävle. Based on two different methods, Energy Balance calculation and Environmental Building, the result of the property's energy use, energy performance and environmental impacts are presented. Except that, measures to reduce final energy consumption are presented. The proposed measures can reduce energy usage by 100 400 kWh / year, which represents a decrease of 18% of the present energy usage. This would represent a total savings of 63 000 SEK per year. In addition, the environmental performance is improved by adopting the suggested measures..

The result found indicates that the overall image of the campaign presented in the news-articles was well in correspondence with the intents of the campaign itself but that the public views where arguably absent..
Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet
The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods.
In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter
In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).
Framtagande av ställbar krok för hängränna
The purpose of this project was to design an adjustable gutter bracket for Lindab Profil AB. Lindab currently manufacture a gutter bracket that is adjustable in angle, however, this model has some drawbacks. One of it´s shortcomings is that it is somewhat difficult for the customer to mount. Another problem with Lindab?s current model is that the design makes manufacturing unnecessarily complex. The new gutter bracket, that we have constructed, does not have these problems. It is adjustable for different roof pitches.
