Konstruktion av mutterdragare för stora moment
This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
Fritidspedagogens möte med ett museum : Fritidspedagogens uppdrag och det pedagogiska arbetet under ett studiebesök
Essay means attempt, and is a paper written based on self-experienced dilemmas, which the writer then returns to, reflect upon and discusses on the basis of literature and accepted theories. In this essay, I reflect upon my own professional role as a leisure-time pedagogue. The leisure-time pedagogue must provide activities that in different ways relate to the curriculum 2011. I have therefore a responsibility to influence the students' desire for knowledge. Focus of learning is different from the one in school, with an emphasis on informal learning.The dilemma is that I am unable to do any pedagogical work at the museum because of many conflicts.

Frilekens betydelse för barn i förskolan : En kvalitativ studie av några pedagogers syn på den fria lekens betydelse för barns lärande
The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.
Var det värt det - Hur prisnivå påverkar uppfattad kvalitet, prisvärde och kundnöjdhet
The purpose of this paper is to examine the effect that price has on quality expectations and customer satisfaction and how price fits into a customer satisfaction model. An experiment in which participants are subject to scenarios of a high or low quality flight are used to test the hypotheses. The analysis shows that perceived quality has a bigger impact on satisfaction than price. Furthermore, price and quality do not affect customer satisfaction independently of each other. The importance of value compared to quality changes whether the actor is a high or low price actor.
Kartläggning av OFP och defektrelaterade parametrar : Inriktning på termisk utmattning
I både kvalitets- och kontrollarbete finns det behov att kunskapsmässigt komma så nära verkligheten som möjligt vid fastställande av defektparametrar för oförstörande provning (OFP). Orsaken är att olika acceptanskrav och bedömningsgränser är svåra att klarlägga när man inte kan förlita sig på att uppgifter är realistiska. I projektet har olika erfarenheter använts för att få en bättre helhetsbild i området för defektparametrar och oförstörande provning.Denna rapport redovisar den inledande delen av forskning och utvecklingsprojektet PLANT 2, där olika defektparametrar kartlagts och en teoretisk bedömning utförts med avseende på hur signalsvaret påverkas för OFP-metoderna virvelström (ET) och ultraljudsprovning (UT) i form av puls-eko (PE) och ?Time-of-flight-diffraction? (TOFD).Definitionen av redovisade defektparametrar följer i stort SKI-rapport 95:70 [1]. Defektparametrar i denna rapport redovisas i bilaga 1.Vid bedömningen av defektparametrarnas inverkan på OFP-tekniker, har drift¬inducerande defekter och tillverkningsdefekter hanterats separat.

Flykt och sökande : en läsning av rörelser i Stina Aronsons novell/drama Syskonbädd
Syskonbädd, or ?Sibling?s bed? in English, is a short story or drama, written by Swedish author Stina Aronson and originally published in 1931 under the pen name Sara Sand. While the story did not attract wide attention for many years, it has recently been republished and performed on stage, as well as aired on the radio. The plot is centered on Harriet, a woman who starts to see the world with different eyes, in a less strict and organized way. Her new view is welcomed neither by her husband nor society, and the book starts with Harriet?s escape from a ?rest home?, where she has been placed by her husband in order for her to return to her old self.

Störningar inom kontrollzon
This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.
Tidsstudie - grovfoderhantering :
Since feeding fodder crops to dairy cows is a heavy and time-consuming but often
disregarded line of work, this study wishes to view the different possibilities that are
currently available to decrease the time to feed and apply this knowledge on an
existing farm. For this purpose, four farms have been studied due to what feeding
systems that are currently used and how long time the feeding required. The occurring
systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle
via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer
which fills an automatic feeder.
Nationella prov- som stöd eller som tidstjuv? : En kvantitativ studie om lärares uppfattning av nationella prov
In recent years, more of high stakes (National exam- NP) have been introduced in Sweden and now (2015) the government has decided that the NP in social sciences- and natural science in 6th grade is optional in order to reduce teachers' administrative burden. Based on these reforms, to have more tests in more grades and also on the decision to remove the test, the purpose of this study is to examine how teachers perceive the work of the (NP).A quantitative research was done in the form of questionnaires. The study was based on questionnaires regarding the time for working with the NP and of the intention that the NP should be a support for teachers.The result of the study is linked to school development and the constructivist theory of learning. The results show that teachers perceive work with NP takes a lot of time, where as the time for administration seems to take slightly lesser time than the time for assessing the exams. The results also indicate that teachers perceive NP as supportive, mainly in relation to the curriculum.
Leka och lära på lika vilkor? : En studie kring fritishemmets arbete om barn med koncentrationssvårigheter
The purpose has been to investigate leisure-time centers actual work on children with attention deficit disorder. In addition, the study strives to make leisure-time centers way of working, in relation to their assignments, visible. The study has also compared how the leisure-time centers work and what the research says. The survey was conducted with the help of three exploratory interviews with pedagogues and three-piece observations at the leisure-time centers. It was carried out at three different schools in two counties in Sweden.The results of the survey show that the schools are trying to create clear procedures, though the centers succeed with this in varied degrees.
Tempus Custode : En GPS-tidrapporteringsapplikation
This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.
