AbstractThe purpose of this investigation was to understand how teachers/pedagogues nowadays work with mathematics in school. In what way can they pin point the difficulties a pupil with another language might have with mathematics.I started the process of this investigation by reading litterature on the subject. Then I did interviews with several teachers and pedagogues teaching in different schools with children at different ages.The results found in my investegation pointed to a lack of practical work with mathematics especially in classroom and revealed from the teachers a strong desire to work with mathematics in different ways.?Talking maths? with pupils in class will help them understand the subject better. Several teachers are of the opinion that the pupils will reach the goals in school with this method.The teachers are also aware of the importance of having practical mathematics.

This master of economics paper discuss that the globalization has lead to increasing internationalization among small Swedish IT- companies in the service sector. Sweden has a long history of foreign trade but in the beginning of the industrialization only large companies that produced goods answered for the foreign trade. Before, the Swedish companies begun their operations abroad in fairly nearby markets and only gradually penetrated far-flung countries. Now this is no longer possible. When small companies nowadays seek growth in other countries there is no time internationalize with the same approaches as before, especially when the company offers a service.

AbstractAnna Celander: Nicolaus Adam Strungks  två sonator ur Dübensamlingen ? Biografi ? analys ? edition. Uppsala Universitet: Institutionen för Musikvetenskap, uppsats för 60p. 2007The aim of this essay is to contribute to the knowledge of the instrumental music of the Düben Collection in Uppsala, by presenting two sonatas by a rather unknown composer, Nicolaus Adam Strungk. A great deal of the music in the Düben collection comes from Nothern Germany so one purpose has also been to investigate if even Strungk's sonatas have stylistic influenses from that region.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

I denna uppsats undersöks huruvida HPM (High Power Microwaves) kan användas som enverkansform i framtida luftvärnssystem för att bekämpa kryssningsmissiler.

Den undersöker även hur ett HPM-system är uppbyggt ochvilken verkan det kan ha på elektriska system i en kryssningsmissil. Vidare diskuteras vilkeneffekt tre olika HPM-system kan ha mot kryssningsmissiler kopplat till de krav som ställs iluftvärnskonceptet.Huvudslutsatsen indikerar att HPM-system kan ha verkan mot kryssningsmissiler. HPM-systemkan nyttjas främst i scenarier där det ställs höga krav på eldhastigheten mot kryssningsmissiler påkorta avstånd.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.

The purpose of this essay has been to investigate if the national test results, in the subject of Swedish B at upper secondary school, are affecting a student?s final grade in varied degree among different teachers. The purpose has also been to investigate if the assessment of these tests is equivalent among different teachers. This particular investigation showed that there are big differences between how teachers grade, in relation to achieved results on the national test. According to the Swedish National Agency for Education, the teacher should take all performance information available into consideration for each particular student.

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.

The purpose of this Master?s thesis is to examine how the gender system is described in chick lit. The analysis is based upon seven chick lit novels. The primary theoretical point of departure is Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes.

För att finna svar på detta analyseras litteratur, svar från enkäter som besvarats av slutanvändare samt resultat från djupintervjuer av systemexpter. Resultatet visar att tekniker som t.ex. ArcSDE och Oracle Spatial kan lösa det angivna problemet.

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.
