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.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

The aim of this work is to demonstrate how the net present value (NPV) at the time of the first thinning depends on the spacing after pre-commercial thinning, and show how net value from first thinning in same stand is influenced. This study is performed with models based on non-distant dependent growth models for single trees. Two different growth models have been used, one for cleaning (pre-commercial thinning) and one for thinning. The first one yields stem density distributed over diameter classes. In the second one, (the thinning model), it is possible to choose when thinning should be done, the thinning method, thinning grade and numbers of thinning.

The aim of my study is to look at two specific schools and their work with Internet in the classroom and compare their work to what experts say about how you should educate. The study focuses on how teachers guide the students to be critical to the information they encounter on the internet. What do the experts say? How should the teachers work with Internet in the classroom? What do the teachers say about their work with Internet? What do the teachers say regarding children and the Internet?  To answer these questions I have interviewed two teachers from different schools, which had classes with children 6 to 8 years old. The schools are very different from each other concerning investment on Internet devices in the classroom.

Background: Of those who start companies, only about 30 % are women. Women's companies also often have both fewer employees and lower turnover. Several efforts are therefore being made to try to influence and encourage more women to start businesses and to get them to expand. Two of these ventures are special network for women and about women entrepreneurs as role models, something that also the theories believe is very important for a more egalitarian business. While entrepreneurship is encouraged for growth in the community, it also has a male character, something that needs to be considered.Purpose: As both the EU and the Swedish government through measures such as Tillväxtverket, is investing large sums to promote networking and role models, we intended to analyze the importance of networking and role models for entrepreneurial women.

Det senaste året har jag arbeta med analys av digital mediehantering, digital media som ett informationsverktyg samt tekniken bakom det. ?Hur kan man göra saker mer effektivt?, ?är webb-tv något för Försvarsmakten att använda sig av i syfte att göra sitt informationsflöde mer effektivt?, både internt och mot allmänheten. Föreliggande arbete tar upp tekniken bakom dessa områden, jag försöker även förklara hur relativt enkelt det kan vara att integrera dem i en existerande organisation utan att göra dyra omorganisationer. Jag har även inventerat AMF och FM media på deras utrustning, teknik och gjort en lista på vad som är användbart och på vad som bör tas bort inför en omstrukturering.

Idén till denna studie kom till mig för ett antal år sedan då jag fick se ett digital skapat verk och därmed bestämde jag mig för att digitalt bildskapande skulle bli ämnet för mitt examensarbete i min utbildning på lärarutbildningen. Därmed valde jag att göra en undersökning om digitalt bildskapande och hur detta skulle kunna användas som undervisningsverktyg i skolans bildämne.Mina tankegångar inför detta arbete var om digitalt bildskapande är möjligt att använda i bildundervisning och ifall detta kan utveckla bildämnets undervisning. Men även undersöka om digital bildskapande är av vikt att lära eleverna och om det kan ses som en tillgång för eleverna och lärarna.I min undersökning använde jag litteratur för att försöka förklara och skapa en bild av ämnet digital bildbehandling. Jag gjorde även en undersökning till mitt arbete med ett digitalt bildbehandlingsprogram för att visa hur digitala metoder och tekniker skulle kunna användas i undervisningen i bildämnet.Resultatet av mina undersökningar med bildbehandlingsprogrammet visade på att digitalt bildskapande är möjligt att använda som undervisningsverktyg och kan även medföra fördelar för bildämnets verksamhet. .

ABB is one of the world?s leading engineering companies in power and automation technologiesand their solutions improve performance while lowering environmental impacts for energycompanies and industries. ABB FACTS designs equipment and plants for series and phasecompensation.This thesis has been performed at ABB FACTS on the Mechanical Design (DM) department inVästerås, Sweden. The purpose of the thesis was to develop and design calculations andsimulation tools for ABB FACTS?s standard series capacitor platforms.

Syftet med denna uppsats var att undersöka om oerfarna lyssnare kan höra skillnad mellan ljud som är komprimerad med en analog kompressor mot samma ljudfiler som är komprimerad med en digital emulering av samma kompressor. Universal Audio Teletronix LA2A kompressor som är en analog enhet och Waves CLA-2A som är den emulerade varianten av samma kompressor ingick i testen för att kunna generera stimuli för jämförelse. Ett blindtest med 16 försökspersoner utfördes för att informera om eventuella skillnader mellan de två typerna av kompression. Resultaten av undersökningen visade att försökspersonerna kunde höra skillnaden mellan båda typer av komprimering..

The aim of this study has been to create a future scenario of what archiving might look like in the future. The main theory used in the study comes from future studies, but also a theory about the social impact of technology on work were used. The questions that were analysed were about the tasks of the archivist, the appearance of the archival institution, collaboration with other LAM institutions, knowledge requirements for the archivist and the amount of archivist positions. The method used in the study was scenario writing, which derives from future studies. The source material consisted among other things of regulations and laws related to archiving together with some archival manuals.The tasks of the future archivist will probably consist of the same tasks as those of present archivists who work with digital archiving, even though archivists probably forever also will have to work a little with paper records.The future archival institution will probably retain its paper records and keep its digital records on digital storage media.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

This essay is about publishing on the Internet and aims to understand the differences between publishing information on the webpage Wikipedia (Swedish version) in contrast to other information pages on the Internet, for example blog, discussion pages, homepages etcetera. The study is based upon an article which described that 90% of the information publishers at Wikipedia belongs to a small elite of white, western, well educated men between the age of thirty to thirtythree. This study examines why people who does not belong to this heteronormativity publish information in other Internet places but not at Wikipedia.Wikipedia is an open source site, where anyone can publish and are even encouraged to do so and is often described as an utopian dream of the digital democracy, so why don´t people express themselves on Wikipedia? The method is based on two discussion groups, which are compared and analyzed. The study is based upon theoretical competence within feminist theory and conceptions such as intersectionality, heteronormativity and digital divide as well as theories about digital devices and social order.

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

Det senaste året har jag arbeta med analys av digital mediehantering, digital media som ett informationsverktyg samt tekniken bakom det. ?Hur kan man göra saker mer effektivt?, ?är webb-tv något för Försvarsmakten att använda sig av i syfte att göra sitt informationsflöde mer effektivt?, både internt och mot allmänheten.

Jag har även inventerat AMF och FM media på deras utrustning, teknik och gjort en lista på vad som är användbart och på vad som bör tas bort inför en omstrukturering. Vidare föreslår jag var en viss utrustning bör lämpligast placeras för att göra mest nytta. Slutligen handlar detta arbete om att skapa en medvetenhet om digital media, och visa exempel på vad man kan göra med denna teknik i en organisation som Försvarsmakten och AMF..
