Förstudie för automatisering av manuell lödning
This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..
Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :
Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply.
The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.
Motorsågskörkortet - en utvärdering av Skogsstyrelsens motorsågsutbildning vid Frossarbo kursgård 2005 - 2007 :
The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.

Vindskador vid stickväg i 1:a och 2:a gallring i Boxholm, Östergötland : i stormen Pers fotspår
Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland
Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108
Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.
Det sociala stödets betydelse vid en sorgeprocess
Någon gång i livet kommer de flesta individer tvingas möta på de svårigheter som en sorg för med sig. Sorg är en reaktion på en förlust. Syftet med studien var att belysa stödformer som kan hjälpa individer i deras sorgeprocess. Där sorgeprocessen i detta fall relaterar till förlusten av en närstående. Deltagarna var 23 stycken kvinnor mellan åldrarna 19-62 som hade upplevt en sorgeprocess till följd av närståendes bortgång.
Visualisering och beräkning av hudkapillärer
The aim of this thesis was to develop an objective and automatic method for identifying capillaries in microscope images of the skin. Furthermore, statistical data about the identified capillaries and the capillary distribution should be computed and stored in a database. The method was implemented using the platform independent programming language Java. An analysis of microscope improvement using various polarization filter setups and wavelength filtershas also been performed, as well as a pilot study of the effect of applying a local anaesthetic cream on the skin. The method is developed and aimed at research on various pathological skin conditions affecting the capillary distribution.
Etableringssamtal
Abstract
I vår studie har vi intervjuat arbetsförmedlare som arbetar med etableringssamtal på Arbetsförmedlingen. Syftet med vår studie var att undersöka hur etableringssamtal går till och vilka faktorer påverkar samtalets utgång. Med hjälp av etableringssamtal så skall de nyanlända etablera sig snabbare och denna insats är frivillig. Vi genomförde kvalitativa forskningsintervjuer med åtta arbetsförmedlare som arbetar på etableringskontoret och som utför etableringssamtal. Resultatet analyserades utifrån samtalsmodellen The Skilled Helper av Gerard Egan, Vance Peavys konstruktivistiska vägledningsmodell samt begreppet gap som är taget från Cognitive Information Processing teori.
Tätortsnära skogsrekreation : fallet Mösseberg i Falköpings kommun
Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

Dyslexi : Några lärares upplevelser av att undervisa elever med dyslexi
AbstractThe ability to read and write is a very important skill in today?s information based society. Most of us learn how to read and write, but not everyone is blessed to do this without struggle. Dyslexia is a very common learning disability and therefore I found it interesting to study how teachers teach students with dyslexia.By studying the literature and by interviewing teachers, I found that dyslexia is a very complex disability. The teachers have to adapt their way of teaching in a way that a student with dyslexia can participate.
Utveckling av reglersystem till quadrokopter
The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
Strategisk/taktisk vägplan :
The purpose of this thesis was to create a strategic/tactical road access plan. This was done by designing an analytical method which gives the road manager a template to create long-term road access plans. The analytical method will help to identify and appraise roads to be upgraded and give information when it is time for building new roads.
The study method involved developing an analytical method. The method was comprised of five main parts: the harvest plan, analysis of the road network, transport costs, quality and storage costs and finally, identification of investment alternatives.
Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014
As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.
Kommunikationsstrategi för Renbruksplan : är det en fungerande modell för samebyarna vid samråd?
The reindeer planning system (Renbruksplanen, RBP) is a communication and planning tool designed for Sami groups. A key purpose of this is that it will act as a tool in consultation with other market players, including forestry. Sami groups have asked for a model of how this can be used in a flexible manner. With the Swedish Forest Agency as a project manager, a communication model for how to use the RBP has been designed. It consists of a number of points divided into ?before?, ?during? and ?after? the consultation.
