Läraren och tjänstemannauppdraget : En studie om lärarstudenters syn på sina framtida tjänstemannauppdrag
The aim of this essay is to examine how future upper secondary school teachers within social science comprehends their future proffessional role. The aim is also to see whether the education is of importance to their Suspension for their future professional role. Focus will especially be on the teachers civil servant role, where the aim is to see how their identification suspends to the governmental expectations on their future civil servant misson. The essay is based on a qualitative method, which is focused conversational interviews.The result indicates that future upper secondary school teachers within social science, who are about to finish their education, have a somewhat deeper sense of identification with the teachers civil servant mission compared to those in the beginning of their education. The result also indicates that the future upper secondary school teachers identification are in line with the governmental expectations on their civil servant mission.
Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd
A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
Undersökning av effekten av böjningsradien på reologi av en tät suspension av flexibla fibrer med hjälp av gallerverk enl. Boltzmann metoden
Denna explorativa studie ämnar generera en hypotes om ett potentiellt samband mellan ögonrörelsemönster och mentaliseringsyttranden. Frågor som ställs i studien är hur ett sådant samband ser ut och hur det skulle kunna mätas. Ett experiment designas där försöksdeltagarna får uppgiften att berätta en sammanhängande berättelse utifrån en serie bilder, såväl berättelsen som försöksdeltagarens ögonrörelsemönster spelas in. Data analyseras på flera sätt; ögonrörelsemönstret jämförs mellan försöksdeltagarna och mellan stimuli, dessutom utförs en närmare granskning av ögonrörelsemönstrens utseende just innan försöksdeltagaren använder ett mentaliseringsyttrande. Slutsatserna som dras i studien är att det finns ett flertal sätt att undersöka förhållandet mellan ögonrörelsemönster och mentaliseringsyttranden.
Bakhjulsupphängning, fyrhjuling
Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel Suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into Suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
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.
Rekonditionering av IBC
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

Drivaxeltrycksreglering hos tunga fordon : För en ökad framkomlighet vid vinterförhållanden
Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air Suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

Realisering av en modulär skogsmaskin - En skalmodell
Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for Suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Prestandaförbättring på en semiaktiv dämpare genom förbättrad reglering
Hydrauliska stötdämpare har länge varit en central komponent på både bilar och motorcyklar. Stötdämpare påverkar fordonets komfort, väghållning och köregenskaper. Dessa olika egenskaper kräver ofta helt olika typer av dämpning och med vanliga passiva dämpare blir resultatet ofta en kompromiss av samtliga dessa. Kompromisserna har lett till utvecklingen av en stötdämpare med ställbar dämparkarakteristik som är tänkt att ersätta passiva dämpare. Öhlins Racing säljer idag ett semiaktivt stötdämparsystem som kallas CES, Continously controlled Electronic Suspension, där dämparkarakteristiken styrs av en tryck- och flödeskompenserad CES-ventil.
Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment
Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the
water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea
(Fr.) Jül. Suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.
