Textens inverkan på matematiska uppgifter : En undersökning om elevers textförståelse av matematikuppgifter i årskurs 5
The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.
Normering av test av intraoral stereognosi och tvåpunktsdiskrimination : Hos barn i åldrarna 5;6 - 7;0 år
The oral sensory ability in children can be assessed through test of intraoral stereognosis and two-point discrimination. Currently, these two tests are not frequently used in clinical settings, and normative data are not always available. The aim of this study was to establish normative data for these two tests in children aged 5;6 to 7;0 years. Further, intention was to compare the results with respect to age and gender. In total 103 children participated, 49 boys and 54 girls.
Automatiska GUI-test : En teoretisk och praktisk studie för hållbarare test
To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.
Analys och kontroll av hållfasthet på grenställsarm
The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
Algoritmer för objektdetektering i SAR och IR-bilder
The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.
National Tests- Teachers' Perceptions of the National Test in English
Syftet med detta examensarbete är att undersöka lärares uppfattningar om det nationella provet i engelska, samt hur dessa lärare arbetar med provet för att kunna hjälpa eleverna att nå sina kursmål. Undersökningsmetoden är kvalitativ då vi intervjuat fyra lärare i engelska på en högstadieskola. Intervjufrågorna har innefattat allt från hur lärare arbetar med det nationella provet och hur de ser på provet, till hur målen med det nationella provet uppfylls. Resultatet av undersökningen är att det nationella provet underlättar lärarnas arbete. Lärarna anser även att provet fungerar som ett bra stöd då de ska betygsätta eleverna.
Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering
The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.
Skillnaden i perception mellan hockeyspelare på professionell kontra icke professionell nivå
Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.
Dubbelkönighet hos mört : normalt eller miljöinducerat?
A number of chemical agents, and their degradation products, have been
recognized as having estrogenic activity on animals. On fish they interfere with
endogenous estrogen and in many cases mimic its activity, thus increase estrogenic
reponse, with elevated levels of vitellogenin. Hence they are called Endocrine
Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of
exposure to estrogenic pollutants. Wastewater from sewage treatment works
contains chemicals known as EDCs, and there are evidence of roach (Rutilus
rutilus) living in recipients of such wastewater having traits of both gender, i.e.
oocytes in male gonads (intersex) on histological examination.
This study was done on roach living in Lake Funbosjön Uppland, Sweden.
Ethics and Animal Experimentation in the Laboratory. A Critical Analysis of the Arguments for"Animal Rights"and"Animal Equality"
Growing up as a child, we had a Dog. To us, it was like a means to an end. That is, hunting other animals for food and for protection, with no special care and treatment given to this animal. Butas days passed by I began to witness a wind of change against such actions. I was made to understand that we were committing two crimes-: using the Dog as a means to an end (for hunting and for eating animals).
Utredning av laserskärningens materialpåverkan inför drag- och slagprovning : Teknisk Fysik med Materialvetenskap
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
Programvaruutveckling för en elektromagnetisk skanner med fokus på användaren, användarstudier och inlärning
The project was based on a request to improve an already existing program and hardware at the electrical engineering department at the royal institute of technology. For maximum ease of use, tests have been done on students to properly design the program for what it is meant to be used for. These tests have been transcribed and analysed, then brought back to the group in a discussion and then transcribed and analysed again, I call this process the ?four step process? (this process is presented and explained in chapter 6.4.). A part of this master thesis was also to analyse the four step process to enhance validity of this research.The project resulted in a new program with a new graphical view and features to help students and researchers to work with the technical tool for electromagnetic readings of planar objects.
