Produktivitet och kvalitet vid stickvägs- respektive beståndsgående förstagallring :
Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110).
The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.
Anpassningar till ekonomiska svängningar bland aktörer inom mötesindustrin : med konferensanläggningar i Stockholm och Göteborg som exempel
AbstractAt the UN Conference on Environment and Development in 1992 the nations stated that traditional environmental policies were not sufficient to handle the multidimensional challenges posed by sustainable development. Governments needed to broaden their political decision making procedures in order to coordinate and integrate environmental, social and economic policies. Therefore a new tool was introduced in Agenda 21, National Strategies for Sustainable Development (NSDS). The aim of an NSDS would be to bring together actors from all parts of society to jointly reach a consensus on how to work towards the vision of a sustainable society. An NSDS would be seen as a strategic tool to help focus national policies for SD.
Filtrering av e-post ? Binär klassifikation med naiv Bayesiansk teknik
In this thesis we compare how different strategies in choosing attribute values affects junk mail filtering. We used two different variants of a naïve Bayesian junk mail filter. The first variant classified an e-mail by comparing it to a feature vector containing all attribute values that were found in junk mails in the part of the e-mail collection we used for training the filter. The second variant compared an e-mail to a feature vector that consisted of the attributes that was found in ten or more junk mails in the part of the e-mail collection we used for training the filter. We used an e-mail collection that consisted of 300 e-mails, 210 of these were junk mails and 90 were legitimate e-mails.
Naturvistelse och fysisk aktivitet som medel för koncentration? : en experimentell cross-over studie
SammanfattningSyfte:Syftet med denna studie var att undersöka om måttlig fysisk aktivitet hade en akut, mätbar påverkan på koncentrationsförmågan. Vidare var syftet att undersöka om vistelse i naturen/och eller bullrig trafikmiljö hade någon ytterligare/särskild påverkan. Slutligen fanns ett syfte att undersöka om det fanns ett samband mellan deltagarens uppfattning av aktuell koncentrationsförmåga och testresultat.Frågeställningar:? Ökar måttlig fysisk aktivitet i trettio minuter den kognitiva förmågan med avseende på logik och matematisk problemlösning?? Ökar måttlig fysisk aktivitet i trettio minuter förmågan till uppmärksamhet med avseende på selektivitet och vakenhetsgrad?? Ger promenad i skogsmiljö ytterligare eller annan effekt jämfört med promenad i stadsmiljö?? Finns det ett samband mellan bra resultat på logik/matematiktestet och deltagarens upplevda koncentrationsförmåga?Metod:Urvalet bestod av kvinnor och män i åldern 22 till 49 år. 14 kvinnor och 6 män deltog.
Ett steg framåt, två steg bakåt? Direktiv 2005/29/EG:s effekt på det svenska konsumentskyddet inom marknadsrätten
På EU:s inre marknad ska fri rörlighet råda. Trots det tvekar konsumenter inför att handla över gränserna. Många konsumenter känner en osäkerhet inför andra länders lagar och oroas över att skyddet mot ohederliga näringsidkare inte är det samma som i deras eget land. Denna osäkerhet undergräver den inre marknaden. För att motverka denna osäkerhet har EU antagit direktiv 2005/29/EG om otillbörliga affärsmetoder.
Kulturers påverkan på förhandlingar
In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.

Hur skall skogen skötas? ? en analys av skogsfastigheten Fagerdal 2:10 i Jämtland
The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined.
A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

Methods: The study was of an empirical cross sectional quantitative descriptive design. During one month, consecutive cancer patients at outpatient units in two Swedish hospitals were asked to participate in the study by completing a questionnaire that had been developed previously for a similar study. All participants had undergone at least 1 cycle of intravenous chemotherapy or a minimum of seven days of oral chemotherapy. Results: A total of 102 patients completed the questionnaire.
Ett Radikalt Högerpopulistiskt Parti i Regeringen : En studie av FPÖ och dess valframgång i Österrike 1999
In this research paper I have interpreted and analysed how it is possible for a Radical Right Populist Party such as FPÖ (The Freedom Party) to obtain electoral success in the end of the last millennium. In 1999 they were elected into the national legislative parliament with 26.9% of the votes and participated in the Shüssel government from February 2000. I believe this is an extreme case study and my method is the so called Disciplined-configurative case study. I?ve conducted this study by using earlier published research and than dividing these old theories into to three analytical categories.
Datorstödd konstruktion och analys av skyddsbur : Hållfasthet och konstruktion
In motorsports competition, safety reasons require that the vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the vehicle body deformation. The roll cage also works to protect the vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

Knowledge Management -lärprocesser över gränser
Background: To be better able to meet the new competition, companies are seeking new competitive advantages, wich is forcing them to review and, in time, change both working methods and corporate structures. This has led to an increased interest in the development of strategies within the field of Knowledge Management. Objective: The objective of this thesis is to improve understanding of how learning in a company occurs over internal boundaries and to investigate whether individuals need to be motivated in this regard. We also aim to give recommendations as to how this can be developed. Furthermore, we will work out a model that explains the learning process.
Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
