Vad orsakar skador på kvarstående träd vid mekaniserad gallring - en intervjustudie

This thesis includes a review of scientific studies of tree injuries following mechanized thinning. Interviews have been made with drivers of single grip harvesters and forwarders in forest thinning and a number of essential factors have been identified as the most important to take into account in order to minimize and/orprevent injuries to stems and roots of remaining trees..

Har en gemensam valuta resulterat i en minskad prisspridning? : En jämförande studie på priskonvergens inom euroländer i förhållande till övriga EU länder

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.

Lagring av flisade skogsbränslen : - med avseende på att minska energi- och kvalitetsförändringar

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

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.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Informationssystem för ärendehantering

Detta examensarbete är genomförd som en explorativ fallstudie på ärendehanteringssystem för att se vilken påverkan dessa system har på företagen som använder dem. Tidigare forskning har visat många fördelar från enskilda funktioner inom ärendehantering och ärendehanteringssystem, men det finns en avsaknad av undersökningar som tittar på dessa system som helhet. Examensarbetet genomfördes som en så kallad single case fallstudie på ärendehanteringssystemet SupportPoint som är utvecklat av företaget Syscom..

Rakrörshantering

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.

Bemötande : En observationsstudie om hur flickor och pojkar bemöts i förskoleåldern

The aim of this study is to examine metaphors and what may be perceived as motif-circuits in Stig Dagerman?s play Den dödsdömde (The Man Condemned to Death) and the two short stories ?Den dödsdömde? (The Man Condemned to Death) and ?Mannen från Milesia? (The Man from Milesia). My intention is to discuss a single theme and identity-marks that unites all three works, using Paul Ricoeur?s The Rule of Metaphor (La mêtaphore vive) as well as the ?thematic critique? of Jean-Pierre Richard.What is metaphor for Ricoeur is for Richard themes (theme): an organizing principle, a sort of schedule around which a world is constituted. Hence, I find similarities between the motif-circuits, Ricoeur?s metaphor-theory and Richards?s themes.

Discovering the RedWave: A cultural study of E.ON Nordic AB-Malmö

Conclusions: A myriad of interpretations are possible when studying and discussing a particular organizational culture. As culture can not be removed from its context, we illuminate the effects that the internationalization process has with regards to unifying the organizational culture in our particular setting studied. Maintaining however, that a reflexive look at this culture shows no single interpretation as being sufficient, we try to expose its richness and ambiguities through a three perspective approach..

Syntetiska Instrument

This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.

Illusion och verklighet : Metaforer och motivkretsar i Stig Dagermans pjäs Den dödsdömde och novellerna ?Den dödsdömde? och ?Mannen från Milesia?

Produktivitet : en motpol till säkerhet

Huvudfrågan i arbetet är hur produktivitet och säkerhet kombineras i de säkerhetslösningar som existerar idag samt huruvida högre säkerhet leder till ökad komplexitet. Det tillvägagångssätt som använts består av en lastmätning av Secure Socket Layer (SSL), och Pretty Good Privacy (PGP), samt en teoretisk jämförelse av säkerhetslösningarna PGP, SSL och Secure Electronic Transaction (SET). Detta innebär att PGP som har jämförelsevis hög säkerhet när det kommer till kryptering även är den säkerhetslösning är mest resurskrävande. SSL däremot är mindre säkert med betydligt lägre resursanvändning. Generellt kan man med facit i hand säga att den lösning som är säkrast även är den mest komplexa.

Trä som fasadmaterial ? behandling och beständighet

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

Utveckling av en diameterklassmodell för grandominerade bestånd i Sverige :

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.
