Omega System Kalibrering: Strål X-Separation mätning och kalibrering

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

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..

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

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.

Barns anknytning i förskolan : Separationsångest mellan barn och pedagog

My essay is about a dilemma that came up on a preschool that I worked in. My purpose with my essay is to examine and to get an understanding for what children with attachement and separation anxiety goes through, and how a preschool teacher the best way can help them.The background story is about a boy named Sixten (not his real name). When separated from one of the preschool teachers Sixten exhibits a great deal of separation anxiety. In the story I give some clear examples of situations where Sixten displays this separation anxiety. I have in the essay viewed it from different perspectives and I have questioned my own role as an educator, but also my entire team.

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.

Uppva?xtfamilj och barns utbildning : En studie av fo?ra?ldrars skilsma?ssa och dess betydelse fo?r barns utbildningsa?r

Allt fler barn i Sverige upplever en skilsma?ssa eller separation, vilket medfo?r ett va?xande ja?mlikhetsproblem da? tidigare forskning visat att fo?ra?ldrars skilsma?ssa eller separation kan ha negativ inverkan pa? barns skolprestationer och utbildningsniva?. Utbildning anses vara fundamental fo?r ma?nniskors livschanser senare i livet och vid en skilsma?ssa eller separation minskar fo?ra?ldrarnas mo?jligheter att sto?dja sina barn i deras utbildning. Med detta som utga?ngspunkt a?r syftet att underso?ka om barn med skilda eller separerade fo?ra?ldrar tenderar att ha fa?rre utbildningsa?r ja?mfo?rt med barn i intakta ka?rnfamiljer.

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.

Magnetisk separering av malmpebbles i KA3 - mekaniska konceptförslag : Magnetic separation of ore in KA3 - conceptual design propositions

This has been a thesis work for an bachelor degree at Umeå university. The work has been done at LKAB?s facilities in Kiruna and its main purpose has been to investigate and construct some conceptual designs for replacing a screen with magnetic separation in KA3 concentrator plant. First all information available about magnetic separation was gathered and studies of magnetic separation at the sorting plant and studies of the plant KA3 was conducted. Companies that manufacture magnetic separators were contacted.

Uppväxtfamilj och psykisk ohälsa : En kvantitativ studie om separation under uppväxten och dess betydelse för psykisk hälsa i vuxen ålder

Med bakgrund i det ökade antalet barn som upplever skilsmässa och separation, undersöker denna studie påverkan på psykisk hälsa i vuxen ålder. Syftet är att undersöka om det finns ett samband mellan skilsmässa och separation under uppväxten och individens psykiska ohälsa i vuxen ålder, samt om ett eventuellt samband kan förklaras av konflikt mellan föräldrarna i uppväxtfamiljen. De teorier som uppsatsen använder för att förklara relationen mellan separation i uppväxtfamiljen och psykisk ohälsa i vuxen ålder tar sin utgångspunkt i ekonomiska svårigheter, psykologisk stress, familjestruktur samt konflikt mellan föräldrar. Studien bygger på kvantitativa data från Levnadsnivåundersökningen (LNU) 2010. Genom logistisk regressionsanalys undersöks om ett samband finns mellan separation och psykisk ohälsa i vuxen ålder.

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.

Blir ko och kalv mindre stressade vid ko-kalvseparation med nos- och slickkontakt än när de bara kan höra varandra?

The aim for this study was to investigate if it is less stressful for cow and calves in loose housing systems when separation is made so they can see and touch each other (Physical Contact-PC) instead of just hearing each other (Hearing Contact-HC). The behavior of eight cow- calf pairs (n=4 pairs per treatment) on an ecological dairy farm with cubicle housing were studied for four hours directly after separation and four hours the day after separation. The first four cows that gave birth were used for treatment PC, and the following four cows that gave birth were used for treatment HC. The only selection criteria used was that both cow and calf were healthy. Separation took place 3-4 days after birth and the calves were put separately in two different pens while the mothers were let loose into the cubicle system.
