Mätprocessen kring propelleraxlar
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.

Undersökning av artikulation, nasalitet och förståelighet hos 16- och 19-åringar födda med isolerad gomspalt
This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.
Musik- och kulturskolans utbud och prioriteringar - Intervjuer med lärare
Den här uppsatsen undersöker lärarnas betydelse för musik- och kulturskolornas utbud och prioriteringar. Den undersöker också deras attityder inom olika områden som skulle kunna ha betydelse för dessa prioriteringar. Undersökningen är gjord enligt kvalitativ metod, genom intervjuer med instrumentallärare vid olika musik- och kulturskolor. Det är mycket som talar för att musiklärare uppfattar att de har ett stort inflytande över beslut som fattas inom musik- och kulturskolan. För det första upplever lärare att musikskolan själv har ett stort inflytande över sin verksamhet och att kollegiet bör vara en viktig grund för de beslut som tas.
Utveckling av barnvagn
After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent.
Materiallogistik vid innerstadsprojekt : En fallstudie av ett innerstadsprojekt i förbättringssyfte av materialflödet
The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.
Bloggar som kommunikation : inom förskolan, skolan och fritidshem
Parents today can be very stressed at the drop off and pick up of their children, this leads to that they sometimes miss important information that is pinned to the walls for example. Papers has the ability to disappear, a blog collects all in one place. Today, almost everything is digitized.This study has examined what a blog is and how schools and preschools can use it. The blog is used as a communication site for the preschools and school. This exam graduate work is made of three blog analysis, the analysis is made to see if the blogs can help the preschool and school to communicate wiht the parents.The theory I have decided to use in this study is the sociocultural theory.
Visuella effekters påverkan på minne och popularitet : Reklamfilm för bilar
Car-commercials are something that many people come in contact with on a daily basis.This is a study on commercials for cars and is focusing on visual effects that are madein post-production. In this report we are trying to find out if and how visual effects incommercials for cars affect how the observer remembers them. The second subjects thatwe use in this report is popularity and we try to find out if and in that case how visualeffects affect the commercials for cars popularity. We also investigated how frequentlycommercials for cars are showed on TV and how the visual effects are in them, it givesa better foundation to the other parts.The methods we applied were interviews, quantitative and qualitative content analysisof car commercials and also observation analysis of the 6 swedish TV-channels thatshows commercials and have the most viewers, to get an idea how frequently thesecommercials are shown. The commercials that were applied in this paper was from late2011 to early 2012.
Mr Chester Jester
Jag har i mitt projekt jobbat med mönsterformgivning och produktion av vävda möbeltyger, digitaltryckta tapeter- och textilier för en fiktiv hemmiljö. Mina designbeslut grundar sig på en fiktiv karaktär, Mr Chester Jester, hans estetiska preferenser och behov i samrådan med mina egna. Arbetets resultat är en gestaltning av världen han lever i, komprimerad till ett hemma hos reportage på gränsen mellan verklighet och illusion. Jag har jobbat med dubbelhet och speglingar - av mönster, av rummet, av tekniker och mig själv. Jag har undersökt illusionens verklighet och verklighetens illusion.My bachelor project is a work of pattern design and production of woven upholstery fabrics, digital prints on textile materials and wallpaper, made for a fictional home environment.
CFD simulering av en fyrtakts Otto motorcykel motor
This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.
Solenergisystem i Kista Galleria
Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.
Sömn och Powernap - Dess betydelse för återhämtning och prestation
During sleep the majority of the body?s production of anabolic hormones is produced and sleep is a general anabolic state of being. It has been to our recognition that a powernap is 4-6 times more effective when it comes to sleep intensity than the last 1-2 hours of a traditional eight hour sleep. With this in mind, and that elite athletes worldwide often sleeps in between their training sessions. This study has tried to prove a hypothesis which comes from the assumption that you can recover and perform better during times with intensive periods with better distribution of your sleep.We have in this study let three test subjects take part of a six week long program with two different training periods for legs.
Trähägn en tänkbar metod för viltskydd i Svenskt skogsbruk?
This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Pedagogers arbete med språkstimulering i förskolan. : En fallstudie.
The purpose of this essay is to describe how preschool teachers think about language stimulation and how they work with it when it comes to small children in preschool. My research questions were:? What kind of methods do the preschool teachers use? And what kind of work procedure do they have?? Is there any difference in the work procedure when it comes to daily routines and playtime?? How do the preschool teachers describe their work procedure with language stimulation?To be able to reach my purpose and answer my questions, I decided to make a case study. I have made observations of the preschool teachers and how they work and I have made interviews. The material that I have used, beside observations and interviews, is literature that is about earlier research about this matter.The result of the study shows that the preschool teachers considers their work with language stimulation as part of everything they do.
