Analys av data från flyglaserscanning :
In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality.
StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data.
The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.
CFD beräkning på en jetmotorinstallation
Hawk Turbine AB tillverkar mindre jetmotorer som ofta används i små obemannade och radiostyrda flygplan. I flygplansmodellen Lockheed T-33 Shooting Star är motorn monterad inuti planet varför luften måste ledas ut till atmosfären. För bästa möjliga prestanda måste ejektorn och utblåsröret som leder luften dimensioneras efter motor och flyghastighet.En 3-dimensionell CAD modell av flygplanets installation skapades och därefter simulerats i en virtuell vindtunnel med hjälp av datorprogrammet SolidWorks Flow Simulation. Flera olika utblåsrör i varierande storlekar samt olika former har testats för att avgöra om ändringar kan förbättra prestandan ytterligare.Simulationsresultat visar att det går att förbättra nuvarande konfiguration med 5,99 % om diametern på utblåsröret minskas från 75 mm till 70 mm med en bibehållen form på utblåsröret..
Frosttolerans hos douglasgran av olika ursprung och tillväxttyp
This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.
?Det verkar som man helst vill vara någon som är blond, smal och glad? : En komparativ studie av två olika chefredaktörers versioner av Veckorevyn
The purpose of this study is to compare the contents, editorials and front covers of Sweden?s oldest girl?s magazine Veckorevyn during two different years, in which the magazine had two very different chief editors.In the year 2000, Emma Hamberg got the job as editor-in-chief for Veckorevyn, with a vision of changing the way the magazine represented young females. She wanted to add a more feminist viewpoint to the magazine, since she felt that Veckorevyn didn?t live up to its claim of being ?a girl?s best friend?. Six years later, the famous Swedish fashion editor Ebba von Sydow became editor-in-chief for Veckorevyn, with the intention of making the magazine better, smarter and more fun for young girls.
En jämförelse mellan två datorprogram för utbytesberäkningar :
This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.
Design av slutsteg med digital PWM-teknik för gitarr
Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

Alla är vi lika men ändå olika. Ett mönsterprojekt inspirerat av kroppen
Sweden has a great tradition of pattern in both wallpapers and fabric, where colours and shape matters a lot for the customer. I have through my examination project tried to expand the views and find new alternatives and shapes for the obvious pattern traditions. I have therefore worked with what could be on the verge of attractive or repelling. To create a curiosity of what is considered to be commercial. From the prospective of the body organs I have created physical patterns for fabric and wallpapers.
Nu ska jag berätta en saga : En studie om hur berättarteknik kan främja läsvärde och läsbarhet i ett informationsmaterial
In this study I have examined how narrative techniques can be used to promote the reading value and readability in information. My focus has been on the communication-agency Mandoly?s information-brochure which function is to inform other companies about their own potential for development in collaboration with Mandoly. The purpose with this study is to examine how it is possible to increase the reading value in order to engage the target group. In my study I have used four methods: analysis of Mandoly?s old information-brochure, literature studies, a qualitative interview, and an user test.

ELVEEL - grafisk identitet till klädmärke
In my project I have collaborated with Linda Larson, who is the creator behind the fashion brand Elveel. The goal was to produce an identity and a graphic profile for Elveel. The aim was that the graphic profile would act as an extension of the clothes aesthetics. I wanted to explore if I by different folding and cutting techniques, in tags and packaging, could reflect the details of the clothes expression. But also how different design elements can reflect the story behind the clothes.
Prislisteoptimering för ett sågverk - Jarlträ AB :
This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result.
The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.
Art and Advertising
The thesis examined whether there is a distinct boundary between art and advertising. The collected data showed how art and advertising are linked to each other and also differ from each other, in particular through the latter half of the 1900?s. What was happening in society came to have great impact on what happened in art and advertising. In postwar Germany, capitalism realism evolved from the German pop art where the art was removed from the art gallery and placed on the streets where the people were, in an era that was characterized by a gap between the rich and the poor.
Utveckling av flödesreaktor : Ett sammarbetesprojekt mellan fakulteten för teknik och naturvetenskap vid Uppsala Universitet och Fagrell produktutveckling AB
This report deals with thecollaborative project between FagrellProdukt Utveckling AB and studentsfrom the Faculty of Science andTechnology at Uppsala University. Theoverall objective of the project wasin addition to developing students'abilities, to help Fagrell withverification and development ofFagrells prototype, Fundamental flowreactor, for flow chemistry. Theuniqueness of Fagrells flow reactor isthat it should be simple andaffordable compared to competing flowreactors in the market.The verification was done bylaboratory and simulation sessions.The verification shows that Fagrellsidea on how to construct a flowreactor is very good.The development included bothtechnology and business. The result ofdevelopments can be helpful for thecommercialization of Fagrell flowreactor..
