Uppföljning av planerat skotningsavstånd med hjälp av geografisk informationsteknologi (GIT)

The cost of forwarding corresponds to about one tenth of the forestry industries raw material cost. This gives a motive to do good follow-ups to get a good overview of the forwarding distance and, thus, enable improvements. Follow-ups are also justified by the possibility to make more accurate calculations of the harvesting costs, if better estimations of forwarding distance are achieved. Today (2009) Stora Enso has GPS and vehicle-computers in most of their forwarders. These are used mainly for the forwarder to follow the tracks of the harvester and for the planning leader to see how the forwarder has been driving within the stand.

Binär matchning av bilder med hjälp av vektorer från deneuklidiska avståndstransformen

This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..

Avståndets blå : En visuell gestaltning av avståndets betydelse i ett erfarenhetsperspektiv

In my degree project, I explore the importance of distance and how our perception of distance is affected by our experiences.During my investigatory work I studied the relation between distance and experiences. Among other things I concluded that distance can refer to several different kinds of distances (for example spatial, temporal or social distances) and that experiences are what you?ve learnt of these distances. The importance of distance can be illustrated by highlighting the effects of the distance, i.e. experiences.My degree project resulted in a pair of interactive binoculars which are used for looking at an virtual world of illustrations in 360°; a world of illustrations where distance and the importance of distance is shown..

Skogsbränsledrivare i klen förstagallring med contorta

The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

Avståndsvarnare till Mobiltelefon

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

Det glömda vanvettet i lokalpressen, NWT 1914-1918 : En undersökning av Nya Wermlands-Tidningens hållning till de tre huvudaktörerna i det första världskriget

I have in this essay looked at what stand NWT took to the three leading countries in The First World War, Germany, France and England, and if it changed during the course of the war.I worked based on the theory that NWT, as a politically conservative newspaper was pro-Germany, which also showed to be true.I have look at the official stand, what is shown in the published material, what stand that the newspaper showed outwards. The result shows that NWT held a neutral stand during the war being loyal to the conservative government. At the end of the war the papers sympathies for Germany are shown more openly in its political material..

En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Var är biblioteket? En användarstudie om distansstudenters biblioteksbehov

The aim of this Master's thesis is to investigate the library needs of distance students. This user study has a student perspective and concentrates on the main question of which way library needs might be expressed by distance students. Associated topics addressed by this study include; the problem of learning centres lacking their own library support, how distance students look upon library support as a concept and whether distance students prefer public libraries or university libraries, and why they make this choice. These questions may give the answer to how distance students deal with information literacy. Theories chosen by the study are in the fields of pedagogical and library science, the social cultural theory by Roger Säljö and in Tom Wilson's theories on user studies and information needs.

Maktavstånd och kommunikation - en studie av upplevda och verkliga kulturella skillnader och deras följder

Hofstede constructed a culture dimension called Power Distance, measuring the inequality of Power. Germany and Sweden have relatively similar values according to his world-renowned research. But a series of interviews of Swedish entrepreneurs in Germany shows that these perceive a large difference in inequality of power in the two countries. This essay seeks to explain the difference between these subjective-qualitative experiences and the objective-quantitative data of Hofstedes Power Distance Index. We propose that a combination of differences in communication, exercise and visibility of power and formality influence the way Power Distance is perceived.

Lärare på distans! : Lärares upplevelser av möjligheter och svårigheter med distansundervisning

The purpose of this essay is to show the opportunities and difficulties of teaching within distance education. I will show this from two different parts of the world. One being Sweden and the other Australia, both countries run a distance education program with similar reasons students whom travelling, some living hundreds of miles from any schools and some students with health and or social disadvantages. This study is based on the actual teacher?s accounts and experiences the opportunities and difficulties in teaching in distance.

Konkurrens mellan rådjur och dovhjort

The main purpose of this report is a first step to cover the scarcely investigated subject of interspecific competition between roe deer, Capreolus capreolus, and fallow deer, Dama dama. The report focuses on the distance between individuals of roe and fallow in the study area as well as which factors that is affecting the variation in distance depending on fallow deer group size and changing population density over time and in two areas. For additional information the history of the populations, such as harvest and distribution, is also investigated. The report came to the conclusion that interspecific competition between the species do occur. The elevated distance between individuals of the two species is clearly significant. The most important factor affecting the distance seemed to be the size of the fallow groups.

Internetbaserade distansutbildningar

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

Enskilda skogsägares mål på avdelningsnivå ? en kvalitativ studie

Half of Sweden's productive forest land is owned by individual forest owners. Research studies show that forest owners have more objectives with their forest than a high net present value, and that the suggestions of the forest management plans doesn?t always correspond to the forest owners? objectives. Through a qualitative study we conducted a discussion about objectives at stand level with the aim of making a more specific formulation of the forest owners? objectives. We asked about the forest owners' objectives at stand level, what forest management they conduct in order to achieve the objectives and how this management affects the net present value of the property. Based on the results of the interviews, we analyzed what kind of factors decide where the objectives place themselves in the landscape and if the objectives at stand level are consistent with the overall objectives for the property. Many forest owners questioned the idea of talking about objectives at stand level, and they didn?t always have their objectives clearly defined.

Kommunikation online : En fallstudie av Korrespondensgymnasiets elevkurativa arbete

The main purpose of this study was to examine how social work can be performed online, by a case study of Korrespondensgymnasiet that pursues distance education. The intention was to determine the possibilities and limits with the online communication between the school counsellor and the pupils. The study was based on qualitative semi-structured interviews with one school counsellor and five pupils and document analysis of three descriptions of the school counsellor?s profession. The theory that has been used in this study is the communication theory: Shannon and Weaver?s Model of Communication and non-verbal communication.
