Att leva i ett kulturellt ingenmansland : En studie om adopterade och deras upplevelse av etnisk identitet i ursprungslandet
The aim of this paper is to investigate how well information and communication technology (ICT) is implemented in the new teacher training program in the subject of Swedish and how this is presented in the applications for examination licence to the National Swedish Agency for Higher Education. This is an interesting field of study, since ICT has been selected, by an investigation chosen by the government to be one of four overall perspectives that are supposed to permeate the teacher training program. There have been several difficulties involved in this project of which one has been the extent of the material. 27 applications and all curriculums in the subject of Swedish belonging to them have been examined. Another difficulty was that the applications and the curriculums are written by different persons under different conditions such as time and resources.
Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.

GIS-stöd för tunga rundvirkestransporter på väg
För att framföra en timmerlastbil med 74 tons bruttovikt i svensk trafik,krävs ett tillstånd från Trafikverket. Tillståndet består av ett dokument somvisar vilka vägar och broar fordonet får trafikera och vilka regler som gällernär man kör lastbilen.Skogsbolaget Sveaskog startade ett examensarbete med syfte att skapamöjlighet att i realtid presentera för lastbilsföraren vilka vägar och broarsom är en del av transportdispensen. Detta skulle ske genom att utveckla ettkartstöd för lastbilens fordonsdator med anslutning till GPS för attvisualisera dispensdokumentet med de angivna vägsträckorna och broarna.Resultatet av examensarbetet är ett kartstöd som använder tjänster frånArcGIS Online för att presentera geografisk information för användaren.Bakgrundskartan består av en grundkarta från ArcGIS Online. Övergrundkartan ligger ett GIS-skikt med vägar och ett annat skikt med broar.Information om huruvida fordonet för närvarande färdas på en väg somingår i tillståndet eller inte, samt information om regler som gäller för broarpå vägavsnittet, presenteras för föraren i realtid. Denna informationuppdateras vid varje uppdatering av GPS-positionen..
Analys av värdeoptimeringen i justerverket : Rörvik Timber
I takt med konkurrensen ökar på marknaden väljer många sågverk att i allt högre utsträckning kundanpassa sin produktion mot de krav kunderna ställer på produkterna. Sågverkens produktion bör vara inriktad på att skapa ett så högt värdeutbyte som möjligt där virkets egenskaper och produktionsanläggningens förutsättningar ställs mot de kundönskemål som finns. (Lycken, 2000)
I sågverkets justerverk sorteras trävarorna i olika sorteringsklasser, även kallat kvalitetsklasser, samt kapas i exakta längder. För att kunna skapa ett högt värdeutbyte krävs det kunskap dels om vilka av träets egenskaper som är avgörande för värdet med dagens sorteringssystem och dels en insikt i hur volym- och värdeandelar ser ut för olika produkter samt hur olika sorteringsregler styr värdeutbytet.
Sedan början av år 2008 har Rörvik Timber Rörvik AB ett BoardMaster-system i sågverkets justerverk som använder färgkamerateknik för att värdeoptimera trävarorna. Examensarbetets syfte är att analysera värdeoptimeringen av trävarorna i justerverket vid sågverket i Rörvik.

Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft
Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.
Rekryteringsprocessen- ett hinder för jämställdhet? : En fallstudie av ett företag där kvinnor är underrepresenterade
Ur ett internationellt perspektiv anses Sverige vara ett jämställt land. Trots detta finnsen utpräglad könssegregering på arbetsmarknaden som ett resultat av traditionellaföreställningar om vad som är kvinnliga och manliga yrken. Träindustrin harhistoriskt sett varit en mansdominerad bransch och det är fortfarande svårt för kvinnoratt få anställning inom den branschen. Vid rekrytering av personal finns möjligheterför företag att förändra den demografiska strukturen hos arbetsstyrkan.Med denna bakgrund ämnade denna studie att undersöka rekryteringsprocessen ur ettjämställdhetsperspektiv på ett utvalt företag inom träindustrin. Företaget har delat insina anställda under två yrkeskategorier, tjänstemän och kollektivpersonal.Underrepresentationen av kvinnor är mest märkbar bland kollektivpersonal och därförstuderades skillnader i hur rekryteringsprocessen ser ut mellan yrkeskategorierna.Studiens resultat visade att jämställdhetsperspektivet inte beaktas i samtliga momentav rekryteringsprocessen.
Kommunal redovisning : Ett verktyg för kommunikation och ansvarsutkrävande
Background: Previous studies have shown that intuition occurs in decision making in small enterprises. However, these studies have not illuminated which decision attributes leads to intuitive decision making.Purpose:The purpose with this study is to contribute with an increased understanding of which decision attributes leads managers in small enterprises to use intuition in decision making and why these decisions attributes have an impact on the role of intuition. The follow-ing research question will be answered in our study: Which decision attributes leads to intui-tive decision making in small enterprises, and why?Method: To answer the research question we have conducted semi structural interviews with managers in small enterprises to achieve a deeper understanding of the role of intuition. We have also used a method called Visual Card Sorting as a complement to the semi structural interviews.Result/conclusion: The result of our study indicates that the relevance and the uncertainty of a decision have the greatest significance in the use of intuition in decision making in small enterprises.

Skånska trähägnader : en studie i konstruktion och historisk utbredning
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
Evaluation of Xilinx System Generator
This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.
Undersökning av Södra-transportörernas användande av KOLA-systemet
The purpose of this study was to create a picture of Södra´s round wood transporters usage, and positive or negative experiences of the KOLA-system. The KOLA-system, owned and managed by SDC, is a program for handling timber orders and displaying their locations on digital maps. The study was conducted as a twenty-three question internet-based survey. Of those asked to complete the survey, 57 percent chose to answer the questions.
The results of the study indicated that several of the transporters found the system quite good and used it to a large extent. The system also had many deficiencies however, and there was clear potential for further increasing the usage of the system.
Metod för urval av bäriga bestånd längs med bäriga vägar i Sveaskogs planeringsområde Råneå och Överkalix :
With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity.
The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program.
The method resulted in four different themes:
1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections.
2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.
Utdragshållfasthet hos limmade och olimmade gängstänger i limträ
This essay examines pull-out strength of threaded rods fixed into glulam timber. The technology is intended to be used in hidden joints between glulam components. The work began with a study of literature focusing on current research within the topic, mainly to create a base of knowledge before the testing was initiated. Studies of scientific articles reveals a lack of research within this area, which makes it difficult to develop standards and calculation models for these joints. The drill holes in the tests have a diameter of 7 mm.
