Mitt examensarbete är en undersökning i att ta tillvara på restmaterial ifrån möbler. Vad kan det medföra i form av estetik och värde? Vad finns det för bra metoder för att ta tillvara på material? Målet är att finna en metod för att förädla ett använt material till något nytt..

Detta arbete har syftat till att undersöka möjligheterna till förbättring av material- och produktionsstyrning vid Sandvik Mining and Construction i Sandviken. Målet har varit att skapa ett underlag för förbättrad styrning av ingående material. Nulägesanalysen visade att förbättringspotential fanns inom klassificeringen av hårdmetallämnen och komponenter. Dessutom var det önskvärt att ett kanbansystem uppfördes på de förslipade hårdmetallstiften som går till den helautomatiska STAMA-cellen. Examensarbetet har gett underlag för en omstrukturering av denna klassificering men även för en framtida uppdatering av den.

Ovarian stimulation in assisted reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested improvements, the most important of which is a white list to avoid misidentifying files that are known not to be trojans..

BAKGRUND: I vår bakgrund redogör vi för den tidigare forskning som bedrivits kring fysiskt undervisningsmaterial i ämnet. Vår teoretiska ram utgörs av Cummins modell för andraspråksinlärning samt Vygotskijs sociokulturella förhållningssätt vilka båda ligger till grund för vår resultatdiskussion.SYFTE: Syftet med vår undersökning är att med utgångspunkt i klassrummets konkreta material studera undervisningssituationer i ämnet svenska som andraspråk, samt undersöka vilka motiv lärare anger för sina val av material och val av aktiviteter.METOD: För att nå studiens syfte använde vi oss utav observationer och kvalitativa intervjuer. I vår undersökning ingår tre lärare på olika skolor som undervisar i ämnet svenska som andraspråk.RESULTAT: I vår undersökning fann vi att lärarna arbetade med ett varierat material och olika aktiviteter i sin undervisning utan att vara styrda av läroboken. Gemensamt för de tre lärarna var att de arbetade med skönlitteratur, läsförståelse och ordkunskap. Resultatet visade också att lärarnas motiv till det material de använde ofta grundade sig på en ambition av anpassning till elevernas tidigare kunskaper och vardagliga liv..

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

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.

Elitskon? is a new type of horseshoe for trotters. It is supposed to give the horse a trot that mimics the movement pattern of a horse trotting unshod. Many horses show a better trot unshod but this can only be used to a limited extent due to the great wear and tear of the hoof. The objective of this study was to evaluate whether the qualities of Elitskon? are similar to the unshod horse or the traditional aluminium horseshoe.

This thesis describes a further development of an existing prototype named Automatic pin bone remover. The further development was requested from the Swedish consulting firm ATM AB. The request of automatic pin bone removers is high and has the potential to be a worldwide leading product.The goal with the thesis work is to further develop an existing prototype. In order to achieve the goal a pre-study of the prototype had to be made in order to define a customer demand specification. The thesis work is then continued by a function analysis which differs from a conservative one.

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Mikael Svanberg skrev 2003 en doktorsavhandling där han beskriver en metod för att givet ett antal olika kandidatarkitekturer välja den som på bäst sätt uppfyller den blandning av kvalitativa krav som ställs på ett system. Denna rapport innehåller en fallstudie av Svanbergs metod applicerad på en webbapplikation beställd av GreenIT. Applikationen ska tillämpa en metod för mätning och relation av ansvarsfullt företagande med ett enkätformulär. Metoden bygger på principialkomponentsanalys (PCA) och är framtagen i ett examensarbete av Helen Josefsson 2009.Svanbergs metod, ?Architechture Evaluation and Selection Method?, appliceras på den beräkningstunga PCA-modulen i applikationen i syfte att utvärdera metoden med avseende på vilken kvalitet resultatet har, hur kostnadseffektiv den är samt när den lämpar sig bäst att användas.Tre stycken kandidatarkitekturer, Layers, Pipes and Filters och Blackboard, och fyra stycken kvalitetsattribut, Effektivitet, Pålitlighet, Underhållbarhet och Säkerhet, väljs ut och används som indata i metoden som bygger på Analytisk Hierarkisk Process (AHP).Metoden visar att Layers tillhandahåller den bästa blandningen av dessa kvalitetsattribut med stor säkerhet.

Då jag varit ute på praktik har jag sett att elever allt för ofta bara sitter och räknar i läroboken. Vi matematiklärare måste bli bättre på att variera och börja laborera i vår undervisning. Både för att få med eleverna kunskapsmässigt i undervisningen och för att få dem intresserade och engagerade. Jag har därför i mitt examensarbete undersökt om lärare i år 4-6 använder sig utav konkret material i sin matematikundervisning. Mina problemformuleringar var:- Vad använder lärare i år 4-6 för konkreta material i sin matematikundervisning?- Hur gör lärare i år 4-6 för att konkretisera matematikundervisningen?- Varför väljer de som konkretiserar matematikundervisningen att konkretisera?Metoder som jag använt i min undersökning är litteraturstudier och intervjuer.

This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations.  The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.

The purpose with this project is to evaluate which of today?s technologies for creating web applications is the most suitable to use when constructing web portals. From a great amount of different technologies, five of the most widespread and well known technologies have been chosen and closely examined on nine different web portal specific criteria. The result from this evaluation is a table where all the grades for each technology is displayed. With the help of this table, it is possible to get an idea about what technology is the most suitable to use when constructing a specific web portal.
