En simuleringsmiljö för distribuerad navigering

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

En lyckad affärsrelation? : två fallstudier

This study has investigated what makes a business relation satisfactory. The purpose is to distinguish the factors that are relevant to a functioning cooperation relationship between sawmills and DIY-stores. The theoretical framework is primarily based on long-term business relationships. The study is based on two case companies and their relations with wood-suppliers. - Case company 1 is a relatively new established and still growing company.

Ett framtida stall för kaninproduktion.

This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

Ljud eller oljud? : planering av goda ljudmiljöer

In our everyday life we are constantly affected by sound; at home, on our way to and from work, when taking a walk through the woods and when we sleep. In discussions about sound one often talk about noise and to what degree a certain noise disturbs us. The positive qualities of a sound and what sounds contribute to the experience of a good environment is rarely discussed. The question of sound and the quality of sound is given more attention through the expansion of Stockholm, the city is becoming both bigger and more crowded. This raises new questions concerning the planning of the city e.g. should the changes of the sound quality in a place be one of the aspects taken into consideration when planning new buildings, are there ways to improve the sound quality in new building projects? Can we even improve the quality of sound in existing places by simple means? I have chosen to study four different areas in Stockholm; Hötorget, Mariatorget, Berzeliipark and Norrmalmstorg.

Den fysiska planeringens påverkan på människans rekreationsmiljöer : tillämpning av de åtta parkkaraktärerna inom balanseringsprincipen

The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.

Skogspolitik i Sverige

For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.

Denim is not dead

För att ett företag ska kunna hålla sig flytande på marknaden idag krävs de att de har hundra procent koll på vad som sker i deras fabriker och att de strävar efter en mer hållbar tillverkningsprocess. Att försäkra konsumenterna om att fabrikerna inte använder sig av barnarbete eller dåliga arbetsförhållanden räcker inte längre utan det krävs en bredare kunskap inom miljö och hållbar utveckling för att den trogna kunden ska stanna. Syftet med denna rapport är att kontrollera det nyuppstartade företaget DENIM IS DEAD?s produktion och utvärdera om hur man kan förädla de olika processtegen samt skapa transparens gentemot kund.Metoden som arbetet utformades efter var genom en fallstudie som är baserad på en mestadels deduktiv metod men med inslag av induktiv metod. Där grunden lades genom en utförlig faktainsamling för att i rapportens senare del kunna analysera de hypoteser och problemformuleringar som ställts.Målet med rapporten var att ta fram en metod eller produkt som ska underlätta kommunikationen med DENIM IS DEAD?s kund.

The French market and customers? perceptions of Nordic softwood offerings

The study of the French market for softwood has been done in collaboration with VIDA AB. The aim of the study was to investigate important product quality and service quality dimensions, the customers? perception of the offering and generally describe the French market and present actors. The market for softwood around the world changes over time and new markets can mean opportunities for the sawmilling industry. The French market is the second biggest European market for softwood, has had presence of actors with sourcing of raw material from the Nordic countries for decades and there is a growing interest for building with wood. Theory being used is about the different dimensions that make up the total quality of softwood, together with intangible dimensions making up the total offering that helps the sawmilling industry to create positive perceived value for the customers. Methodological approach in the study was a case study research design, aimed at providing knowledge about one specific subject in one context. The general description was mostly carried out by literature studies and data from various statistics sources.

Mätramar för vederlagsmätning och timmersortering på sågverk

The measuring of logs is important in the sawmills process to the sawn products. The technology of automatic wood measurement is continuance developing. This study has the purpose to see how the different techniques and the routines works of measure frames for determining of wood value and sorting in sawmills. The study is performed as a literature study and a survey. The survey includes some of the Swedish sawmills that produce more than 10 000 cubic meters sawed products per year.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Virkesgripen, ett geometriskt verktyg :

The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins. Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions. The study showed that it is the durability the users give priority to.

Traditionell skidtillverkning: ett kunskapskomplement till dokument?ren Skidmakaren i Gielas

Archaeological findings show that ski manufacturing goes back thousands of years in the Nordic region. There is a wealth of literature and film that deals with the subject, but it can be difficult to get an overall picture of how a specific type of traditional ski has been made. The starting point is the documentary "Skidmakaren i Gielas", where the viewer can follow Alfred Israelsson as he makes a pair of skis out of birch wood. However, the documentary lacks important information about how the skis are actually manufactured. Length, width and certain working steps are disclosed.

Skogsentreprenad idag och i framtiden : en kvalitativ studie av skogsmaskinentreprenörersverksamhet och framtidsvisioner

The Department of Forest Products and Management, Swedish University of Agricultural Sciences has received means from Vinnova for a preliminary study of the organisation of logging work of today and how a better logging organisation should be brought about. This thesis reports results from qualitative interviews with nine forest machine contractors regarding the situation of their companies. The interviews have been analysed with respect to the genesis of the companies, which tasks they perform or that they could consider perform-ing, business relationships of the companies, relationships between the different partners of the companies, and the state of competition experienced by the contractors. The companies have developed either from the contractor previously being machine operator employee or from that the contractor in making has owned a machine and needed work. Their primary business is mechanised logging.
