Automatisering av flexibel fixtur
This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.
Artrika vägkanter - hur påverkas de av slåtter och underhållsdikning?
ABSTRACT
This study is an exam work at the Department of Ecology at the Swedish Agricultural University, Ultuna, Uppsala. The field work was performed in the counties of Uppsala and Västmanland.
Grassland areas, exposed to annual mowing, are known to host a variety of rare and red-listed vascular species. The area of these grassland are, however, decreasing in the landscape due to modern farming. The fact that roadside verges maintain regular mowing has proven to be a successful concept for many rare vascular plant species in this habitat.
Vascular plants along roadside verges at the State road network were inventoried due to a government mandate during 1995 and 1996. As a result ?Species rich roadsides? were pointed out.
Hur stor areal äldre skog lämplig för trakthyggesbruk finns det på Gotland 2013?
The degree project at hand investigates how large areas of older forest (80 plus years) suitable for clear cutting there is on the Swedish island of Gotland. Large areas of older forest on Gotland are situated on land with shallow soil depths which are economically uninteresting and often unsuitable for clear cutting forestry. Other forests hold big nature conservation values and should not, or cannot, be used for forestry purposes.
The survey is made as a GIS analysis based on the old but carefully made ?Brief forest inventory? (ÖSI) made in the 1980s and early 1990s. A sample from the inventory is combined with studies of orthophotos, satellite photos and other GIS layers that display estimated soil depth and nature conservation values.
Partly contrary to common belief, the survey shows that there are still large areas of older forest suitable for clear cutting forestry on the island.
Concept Cartoons och Jorden som en planet i rymden: kan
seriefigurer skapa kvalitativa elevdiskussioner?
Syftet med vårt examensarbete var att ta reda på om användning av Concept Cartoons, som hjälpmedel vid naturvetenskaplig undervisning, kan skapa elevdiskussioner som har sådana kvaliteter att det gynnar naturvetenskaplig begreppsbildning. Till grund för arbetet ligger Lpo 94, kursplaner och tidigare forskning. Undersökningen genomfördes i en skola i Östra Norrbotten och undersökningsgruppen bestod av 12 elever i år 5. Undersökningsunderlaget samlades in genom bandinspelningar av gruppdiskussioner, enskilda elevintervjuer samt observationer. Resultatet visade att enbart Concept Cartoons som hjälpmedel inte är tillräckligt för att skapa kvalitativa diskussioner.
En granskning av det internationellt använda frågeformuläret International Outcome Inventory for Hearing Aids (IOI-HA).
Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.
y måste bero av x ? gymnasieelevers förståelse av det matematiska begreppet funktion
Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.
Diagnosens betydelse : En grupp pedagogers uppfattningar av diagnosens betydelse
The thoughts of a common school for all children have been around since the 1800?s but was something that was introduced in Sweden first in 1962. When the curriculum for primary school came in 1980 there was a new concept, a school for all. With a school for all it was aimed that all children should have the right to participation and a common education no matter what needs they could have.During my education I have come across the concept a school for all and that is something that interested me. Today?s curricula and school laws aim to ensure that all children have the right to equal education and inclusion whatever needs you have.The purpose of this study is to find out some pedagogues? thoughts and work around the concept a school for all.
Energieffektivisering i kommun
AbstractThe Municipality Council decided in 2010 to develop a comprehensive energy efficiency strategy with financial and methodological support from Energimyndigheten (The Swedish Energy Agency). The strategy should include 3 major parts: an inventory of the 2009 energy use defining the current situation, the 2014 and 2020 goals for energy use, and an action plan for goal achievements. According to Energimyndigheten, the strategy must include all municipal administration premises, vehicles, and all majority-owned companies (as Laholmshem, the municipal housing company).The report describes the inventory work in order to obtain the 2009 energy use and the sources of information used. The inventory values are used as the base year values for the 2014 and 2020 goals. The inventory showed that information about the vehicles is dispersed in the municipal administration and no clear structure exists with respect to mileage and fuels used.
Biståndshandläggares uppfattning av begreppet skälig levnadsnivå och handlingsutrymme. : En kvalitativ studie.
Our aim of this study is to analyze how the concept of reasonable standard of living is by assistance officers in geriatric care, as well as the impact of their discretion on the assessment. We conducted a qualitative study with the help of interviews. During the collection of the empirical material, we have experienced greater confusion among assistance officers opinion about the concept of reasonable standard of living. We lacked a clear answer to the concept content. The interview subjects' responses did not differ so much, they said, among other things, that the concept is difficult to interpret, fuzzy, or that they do not have a good understanding of it.
Gryning i den svarta lådan. Hur man utifrån rationella metoder och ett beskrivande angreppssätt kan öka förståelsen för kompetens
Competence is a complex concept that encompasses many facets. This study aims fora better understanding of the concept. Many branches of business administration science would benefit from a better understanding of competence and, through that understanding, find solutions where competence is one of many variables. By combining a positivistic and phenomenological approach, this study has created a broader understanding of the concept of competence.The study combines systematic study of the relevant literature with in-depth interviewswith people representing both the employer and the union within the staffing company world.The results show that quantifying competence is a complex and next to impossible task, as it would involve including the whole concept of competence in the calculations. When this is done, the phenomenon itself becomes so complex that it loses its validity.This is why theorists who want to perform this type of calculations put most of the competence complexity in ?the black box?.
Lövskogens förändring i eklandskapet söder om Linköping : 1927 jämfört med 2013
The forests of Sweden are constantly changing. Map studies indicate that the amount of deciduous trees in Sweden has decreased in recent years in favor of the coniferous trees. The National Forest Inventory has since the early 1920s monitored the Swedish forests and in recent years has made the old data digitally available. In the present project, we have investigated how the numbers of stems in different diameter classes have changed for birch and other deciduous trees. The inventory was conducted in the same manner as in the first forest inventory.
Layers of land : the palimpsest concept in relation to landscape architecture
This paper researches how the palimpsest concept is used in relation to landscape, and how it can function as a tool within landscape architecture. Palimpsest originally refers to old parchment handwritings, where new text has been applied on top of effaced, but still discernable, earlier writing. Superimposition of information is the core of the palimpsest concept, used within a range of scientific as well as cultural fields. The purpose of this paper is to find how a landscape palimpsest can be distinguished among the many different layers of landscape, such as historical or cultural, and to examine the potential use of the concept in theory and practice of the landscape architecture field. The study is conducted as a literature survey, examining the use of the palimpsest concept within academic works related to landscape.
