Syftet med mitt examensarbete var att få mer kunskap om konkreta material som behandlar multiplikation och division. För att få veta vilka konkreta material som finns att tillgå gjorde jag intervjuer med två lärare som fick beskriva vilka material de använder sig av. Jag valde att observera två elever enskilt då de löste de multiplikations- och divisionsproblem som jag hade designat för studien. Det jag fick ut av undersökning var att det finns många olika material som elever kan arbeta med samt att det är viktigt att de får möjligheten att arbeta med dessa material. Jag kom fram till att lärare bör vara medveten om i vilket område som materialet är bäst tillämpad och att elever behöver använda sig av konkreta material för att lättare förstå uppgiften.

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews.

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping.

DinBox Sverige AB säljer fastighetsboxar på den skandinaviska marknaden och har produktionen utlagd till en leverantör Kina. Företaget startades i slutet på 2007 och är med andra ord relativt ungt. Den logistiska delen från beställning till leverans av produkt, är en mycket viktig och vital del av verksamheten som måste fungera. Det logistiska flödet fungerar idag inte helt felfritt och det uppstår problem med leveranser.Jag fick som uppgift i mitt examensarbete inom supply-chain management, att undersöka det logistiska flödet närmare för att hitta olika förbättringsförslag.Syftet med uppgiften är ta reda på vilka fel som uppstår, kartlägga vilka typer av kostnader dessa fel innebär och utreda hur man kan undvika fel i fortsättningen. Examensarbetet ska resultera i ett passande förbättringsalternativ som ökar kontrollen av logistikflödet från beställning till leverans.Resultatet i examensarbetet har uppnåtts genom en grundlig nulägesanalys, framtagande av ett flödesschema och identifiering av problem i processerna.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

In classic academic social studies of East Europe, terms as Communism and Post-Communism are commonly used to describe the main characteristics of this geographically imagined area.
