The aim of this thesis is to investigate, and thereby highlight, the new role of special needs teachers in conducting educational development in the fields of linguistics and literacy. The thesis defines how educational development, as described by special needs teachers, can be conducted and what conditions they perceive for such development. Factors which, according to special needs teachers, promote or hinder the development are discussed.The study uses a qualitative method involving knowledge-creating dialogues, analyzed hermeneutically, with two special needs teachers. Results are then discussed in light of relevant research and sociocultural theory. The study indicates that special needs teachers? main tool, to support teachers, is diverse use of dialogue.
Modellering, identifikation och reglering av en quadcopter
SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.
Drapering av en illusion : En komparativ studie med utgångspunkt i fotografierna av Leila Khaled och Shirin Neshat
The aim of this paper is to perform a comparative study between the photography?s of Leila Khaled and Shirin Neshat in order to observe if the woman are able to recede from an conventional formation to become the bearer of the veil and not only reduced to that whichneeds to be concealed. From a feministic perspective I have observed how the symbolic of the veil moulds the woman and how the woman in her context moulds the veil.In the description of the news photography of Khaled and the art photography produced by Neshat the mechanisms that lies as a foundation for the modelling of the portraits becomesthe essays primary entrance. Mechanisms that evolve around the creation of the woman as aconcept, a subject shaped for being looked at and the woman?s self-image through others.The textual discourse is visually enhanced through a comparative picture material visually enhanced and explained through photographs by the contemporary artist photographers Cindy Sherman, Catherine Opie, Laurie Simmons, Robert Mapplethorpe and Elin Berge.
Analys av turbulensmodeller för CFD
This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Förrotation till omrörare
The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
Produktutveckling av ostpress
AASS (Applied Autonomous Sensor Systems, Centrum för Tillämpade Autonoma Sensorsystem) arbetar med forskning inom autonoma system. Deras stora användningsområden är utveckling av automatiska system till fordonsindustrin samt system till äldrevården.AASS, har ett önskemål om en enklare modell av en CNC fräs för enklare fräsning till bland annat prototyptillverkning. Fokus ska ligga på kostnaden då precisionen inte är av största intresse.Uppdraget innebär att ta fram en konstruktion av en cnc- router med tre axlar med ett arbetsrum på 600x450x150mm. Maskinen ska kunna skära i mjuka material som trä, plaster men även mjukare aluminium.Resultatet är en tre axlig cnc- router som drivs av tre stycken stepmotorer som är kopplade till respektive kulskruv. Cnc routern har ett arbetsrum på cirka 600x450x150mm.
Hinder och möjligheter med jobbcoachning : utifrån jobbcoachers och arbetssökandes syn på insatsen
Abstract This qualitative interview study focuses on job coaching by examining what thoughts, views and opinions the involved parties, such as job applicants and job coaches, have of the contribution. The aim is to highlight the obstacles and opportunities by examining the expectations that exist from both parties as well as how to look at job coaching and its different areas. In this context, examine the similarities and differences between the two parties approach to the contribution. This is made possible through four interviews with job applicants as well as four interviews with job coaches. A grounded theory inspired approach was used to obtain the results of the study.
Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Tvådimensionella rum
We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.

Bättre arbetsberedningar med hjälp av BIM : Hur de kan utformas för implementering av BIM
During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.
Unga idrottares upplevelser granskat genom flow-teorin
Skolan har fått i uppdrag att implementera hållbar utveckling i undervisningen. Enligt skolverket ska hållbar utveckling genomsyra all utbildning. För att undersöka hur lärande i hållbar utveckling har implementerats i undervisningen intervjuade jag sex lärare på en gymnasieskola. Lärarna som intervjuades arbetade som naturkunskapslärare, fysiklärare och samhällskunskaps-lärare. Studien visar att de intervjuade lärarnas syn på vad hållbar utveckling i undervisningen innebär varierar.
