SvenskaDetta är en kvalitativ studie som är baserad på semistrukturerade intervjuer. Syftet med detta arbete är att ta reda på hur två matematiklärare och en specialpedagog ser på/beskriver matematik­svårigheter och hur de arbetar med elevernas matematiksvårigheter som de upp­täcker hos sina elever. Jag är väldigt intresserad av att höra vilka matematik­svårigheter och orsaker till matematiksvårigheter lärarna ser hos sina elever samt lära mig hur skolan och lärarna jobbar med dessa svårigheter hos eleverna. Samtliga informanter hade samma svar på mina forskningsfrågor. I resultaten av hela min studie har jag kommit fram till att orsaker till elevernas matematiksvårigheter bland annat är: dåliga baskunskaper, låga baskunskaper förståelse av positionssystem samt begrepp.

I vilken grad ett barn är fonologiskt medvetet är i många fall avgörande för hur barnets läsinlärning kommer att fortlöpa, varför det är av stor vikt att redan tidigt arbeta för att stärka den fonologiska medvetenheten. En tillfredsställande läsförmåga är central för inlärningen även i andra skolämnen än svenska. Forskning har på senare tid visat att det finns ett tydligt samband mellan läs- och skrivsvårigheter och svårigheter i matematik. I denna studie undersöks huruvida det finns någon koppling mellan tidiga fonologiska svårigheter och matematiksvårigheter två år senare hos en grupp elever. Med kvantitativa metoder och genom analyser av bedömningar i olika diagnos- och kartläggningsmaterial har ett resultat kunnat presenteras som visar att majoriteten av de elever som i förskoleklassen uppvisade tecken på fonologiska svårigheter även hade matematiksvårigheter i år 2.

Hur man kan arbeta med matematik i grundskolan, år 4-6, på ett varierande och verklighetsnära sätt. En studie av litteratur om detta och lektionsförslag utifrån litteraturstudien samt Internet och grundidéer från praktiktid..

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

The aim of my examination work was to compare and research how russian respective swedish teachers make use of educational aesthetic methods such as drawing, drama, music and dance in the teaching of core school subjects ? mathematics and swedish respective russian languages. The aim of this work was to find out which of these methods are used by pedagogues in the process of education and on what level are they integrated into the theoretical pedagogic work. The point was to also analyse the regulation documents used as pedagogical base in schools i've been doing my survey in. This was done to partly find out what arts perspective is given in the curriculum and partly to see what pieces of it are reflected in the process of education.

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable.

The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.

There has been an increasing interest for ranking of Swedish health care and a lot of emphasis has been placed on the creation of indicators in order to rank hospital units. However, essays on to what extent the choice of statistical method affects the final result of the ranking of health care units have not been given the same attention. For this particular reason, the main objective of this essay has been to investigate whether the choice of statistical model has a significant impact or not on the final result, by using five different, more or less common, statistical approaches: bar charts (with and without confidence intervals), control charts, logistic regression, multi-level analysis using shrunken residuals. The analyzed material in the essay comprises 24119 patients that all have been prescribed some form of the lipid-reducing medicine statin. According to directives given by Region Skåne, doctors are encouraged to prescribe a particular type of statin medicine, namely Simvastatin, which has been proved to be equally effective, but significantly cheaper than other statin medicines.

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

En teoretisk kontroll av luftvärnsbataljonens sjukvårdsfunktionSyftet med detta arbete är att inom ramen för funktionsmålsättning för Försvarsmaktens hälso- och sjukvård kontrollera om luftvärnsbataljonens sjukvårdsfunktion enligt org. 09 är korrekt dimensionerad. Frågeställningen är: När, med hänsyn till grupperingsgeometri, medicinska tidskrav samt evakueringskapacitet blir sjukvårdsfunktionen en begränsande faktor för luftvärnsbataljonen. För att svara på detta jämförs luftvärnsbataljonens TOEM med kraven ur funktionsmålsättning för Försvarsmaktens hälso- sjukvård i syfte att kontrollera om sjukvårdsfunktionen ges förutsättning att lösa ställda uppgifter. Vidare analyseras faktorerna, aktionsradie, förlustskadeberäkningar preventiv medicin, samt evakueringskapacitet och grupperingsgeometri.Den viktigaste slutsatsen ur arbetet är: Det är inte sannolikt att samtliga enheter inom bataljonen kan åtnjuta möjligheten till adekvat sjukvård inom de tider som de medicinska kraven ställer..
