Detta examensarbete är den avslutande delen av utbildningen inom maskinteknik på Linnéuniversitetet i Växjö under våren 2013. Arbetet utfördes i samarbete med Rottne Industri AB där skogsmaskiner utvecklas och tillverkas för skogsbruk. Projektet innefattar utveckling av en hjulupphängningskomponent kallad ?hjularm? tillhörande företagets ledande produkt, skördaren H-8. Resultatet slutade i en ny design av hjularmen med hjälp av CAD-modellering, Systems Engineering och FEM-analysering..

Detta arbete är en reflektion över ett programvaruutvecklingsprojekt, WAIS, och den arbetsmetodik som användes för detta projekt. Arbetsmetodiken för utvecklings-projektet var Extreme Programming (XP) och vi ifrågasätter om detta val var lämpligt för ett projekt som WAIS. Projektet genomfördes vid Blekinge Tekniska Högskola under våren 2004. Utvecklingsprojektet WAIS var en del av ett större projekt, AIS 42, som stöds av VINNOVA. Huvudprojektets bakgrund och syfte beskrivs för att läsaren skall förstå den roll projektet hade. Studenternas uppgift har varit att utveckla en prototyp för ett system som skall sprida information relaterad till logistik och transporter.

This essay is based on students' growing lack of interest in science at school. Both from a democratic and social perspective, this is a worrying factor for the future. Through observation, I investigated how five science teachers conduct their teaching. This is to get a better understanding of how teachers' behaviour in the classroom can affect students' interest in science. With a socio-cultural research approach, I have tried to highlight a few pieces of the puzzle that may explain students' declining interest in science.

Domestic science is an interdisciplinary subject. Furthermore domestic science is a combination of theory and practice. The basic competence, a recommendation from ?The Swedish School Institution? (Skolverket), is to enter the secondary school with minimum grade G, (godkänd) in the basic themes: Swedish, English and Mathematic. Today there are many pupils finishing their secondary school without grade in one or more basic themes; Swedish, English and Mathematic.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

Syfte och frågeställningar 1. Finns det ett samband mellan tiden mellan fotisättningarna (främre respektive bakre fot) och sparkhastigheten? 2. Hur påverkar bakre fotens kontakttid sparkhastigheten? 3.

ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Med tankar från pedagogen Montessori och filosoferna Platon och Baudrillard har detta arbete behandlat frågor om datorn och dess betydelse för en grafiker. Frågeställningen formulerades efter hand och lydde tillslut: ?Hur kan materia te sig i digital form?? Forskningen resulterade i en hypotes för hur digital materia skulle födas i datorn: genom att blanda två uppsättningar av data, såsom två genuppsättningar tillsammans skapar en ny organism. Under produktionen utvecklades därmed en metod för hur en grafiker ska kunna skapa tillsammans med en dator. Syftet är att ge andra grafiker ett nytt sätt att se på digital grafik.

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

During the last decades the evolution of information technology and the increasing ability to access information have been discussed in many ways. In the beginning the focus was on the technology but now the discussion is more and more about the use of information and how to develop knowledge out of it. There is an ongoing discussion about the difference between knowledge and information. The subject of this Master s thesis is to find out if and how the Swedish elementary school has written into its mission statements to help the pupils to become information literate. For this purpose I have examined literature about information literacy and pedagogic as well as legislation and other documents that control how the Swedish elementary schools work.

During the last few decades a new kind of business operation have developed and this hasforced organisations to adapt themselves to a new competitive environment characterized byincreased customer demands as well as a larger amount of competitors. Therefore companieshave had a shift in their strategies from focusing on sales numbers to focusing on thecustomer. To build lasting customer relationships, in order to create customer loyalty, havebecome an important part of the organisational strategy and the collection of consumer datais essential in achieving this loyalty. Customer relationship management systems assistorganisations in managing information about individual customers as well as managing allaspects of customer contact, with the purpose of increasing customer loyalty towards thecompany. The collection of consumer data also enables for companies to design personalizedoffers to individual customers in the form of direct marketing.

Scholarly publishing has since the introduction of electronically distributed periodicals seen a time of change, mainly in the STM-business (Science Technology and Medicine). The roles of the three main participants in the publication process; researcher, publisher and library are developing into new directions. Researchers themselves are taking a more active part in the discussion, with the boycott list from the Public Library of Science organization as an illustrating example. Reforms are being launched partly as an economical and efficiency issue, partly as an increasing desire from researchers to maintain the control of scientific end result. This Master s thesis examines how the partly conflicting goals of the participants affect the conditions for scholarly publication in an electronic environment.
