… Workbench. An organized design of experiments is used to find the optimal geometry of the caliper. A free form fabrication model of the concept is built which are used as a probe when moulding a cast iron prototype of the concept. Two types of practical tests to measure the …
… The purpose of this work is to show its validity for a real and complex engine geometry, covering a longer simulation interval then previously. After an initial description of the mesh creation process, studies of the in-cylinder charge motion, created during the intake stroke …
… the first phase valuable knowledge is obtained according to the movements and geometry of Elmo. Furthermore a series of ideas and concepts are developed and evaluated for different parts of the robot. Among them can we find an innovative construction for the axis which is later …
att planlägga ett hus under järnåldern
This essay concerns the interpretation of house plans in three-aisled longhouses and hall-buildings, in Scandinavia during Iron Age. Full scale house reconstructions need a better basis of interpretations to understand the patterns of roof supporting post holes in excavated …
Hur arbetar pedagoger med matematik utomhus på förskolor med olika pedagogiska inriktningar (traditionell, i ur och skur och Reggio Emilia)?
… activities. There is a difference in whether they focus on counting, geometry, or pattern.
4DFrame, hur kan man arbeta praktiskt med det?
… critical, however, stated that the new teaching material is suitable to teach geometry.
för elevers lärande i geometri
Syftet med den här rapporten är att se om elever som har svårigheter inom ett specifikt matematiskt område får den undervisning de behöver för att nå upp till målen. En diagnos gjordes med elever i år fyra inom området geometri. De har därefter haft en lektion där en pedagog …
? tekniken, marknaden och hur de utvecklas
… will be broader and the products are becoming more sophisticated in terms of geometry and accuracy. The number of customers is increasing, thereby reducing dependence on any single industry, customer or product.
Virvelpanelmetoden
… panel method, with vortex singularities distributed over simplified airfoil geometry. The resulting velocities are then used to calculate the pressure distribution and lift of the airfoil. Comparison with wind tunnel tests and data from commercial software show the limits of the …
… three and five years acquire basic mathematical concepts, basic numeracy and geometry. The aim is also to find out whether teachers feel that the size of the group of children affects their learning. The study contains information about what preschool teachers think about the …
Hur lärare undervisar i geometri i de tidigare skolåren
Ett flertal både internationella och nationella undersökningar visar att svenska skolelever blir allt sämre på matematik. Ett delområde som ofta utpekas är geometri. Denna undersökning syftar till att ta reda på hur ämnet geometri har utvecklats i den svenska skolan samt vilka …
… Den andra metoden kommer från artikeln ``Discrete Differential-Geometry Operators for Triangulated 2-Manifolds'' av Mark Meyer, Mathieu Desbrun, Peter Schröder och Alan H. Barr. Deras approximationer av krökningarna kräver en triangulering av ytan, vilket de inte ger någon …
En enkätstudie av gymnasielärarens förhållningssätt till matematiska bevis
Practice of mathematical proof increase the understanding of mathematics anddevelop creativity skills, problem solving, communication, logical thinking andreasoning which are all important tools not only within the subject of mathematicsbut also important tools for the society …
… something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to …
… in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be …
