Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.

The Civil Engineering office in Skellefteå needs to develop the users' participation in the planning of parks and playgrounds. In order to get such a procedure to work one have to find a method that can work in the daily activity. My work aims to find such a method and to implement it in practice. Apart from helping the Parks departement to find an functional method I will also develop a deepened knowledge about users?participation wich can be very useful i my future profession. This work can be divided in three stages.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

I denna rapport beskrivs användning av Bluetooth i laservapen, även en fördjupning inom Bluetooth. Vi fick i uppgift att skriva en manual om hur konfigurationen av laservapnen gick till. Vi skulle ta reda på så mycket som möjligt om Bluetooth lösningen, vilka funktioner som fanns och vilka funktioner som kunde implementeras samt att ta reda på hur man implementerar ett program till vapnen..

It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.

Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.

VARN A network multiplayer 2D action game written in Java. All games that support any form of play across networks is in one way or another affected by the delay, or "ping", that occurs from the time it takes for information to travel over the wires. Not only does it take time, it varies depending on how far away the connected partner is and the current status of the network you are on. Through the years a lot of different methods have been developed to combat these delays. I have reviewed some of these methods and implemented a synchronization system in Java meant to be used in online action multiplayer games..

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

This master theses deals with different methods for automatic tuning of the existing controller for external axis. Three methods for automatic tuning have been investigated. Two of these are based on the manuell method used today. The third method is based on optimal placement of the dominant poles. Different sensitivity functions are important for this method.

Usability is a field within systems development which doesn?t get the attention it might deserve. Above all, it?s considered time consuming and expensive by many people in the industry. The current information regarding low-cost alternatives to achieve a more usable system seems to be almost non-existent.

Syftet med denna studie var att ge en djupare inblick i pedagogiska tanketraditioner och med ett musikpedagogiskt kunskapsintresse undersöka vilka intentioner och konventioner som låg till grund för kommunikation av musikaliska kunskaper i historiska manualer. Förord ur fyra manualer från två olika århundraden studerades; en instrumentskola och en musikteoretisk manual från 1500-talet och en instrumentskola och en musikteoretisk manual från 1700-talet. Manualerna var Silvestro Ganassis Opera intitulata Fontegara från 1535, Thomas Morleys A Plaine and Easie Introduction to Practicall Musicke från 1597, Johann Joseph Fux Gradus ad Parnassum från 1725 samt Johann Joachim Quantz Versuch einer Anweisung die Flöte traversiere zu spielen från 1752. Med en kombinerad metod analyserades förorden i tre nivåer för att se hur musikaliska kunskaper kommunicerades dels på ett individuellt plan, dels på ett mer socialt orienterat plan. Studiens teoretiska ansats utgjordes av ett övergripande kulturpsykologiskt perspektiv, vilket gav möjlighet att vetenskapligt belysa relationen mellan individer och traditioner och därmed också förbinda studien med dagens musikpedagogiska praktik.

 SAMMANFATTNINGVårt projektarbete har omfattat en totalrenovering av en 6-cylindrig Jaguar motor från 1968. Dennadel har varit det sekundära syftet i vårt projekt. Den primära uppgiften har varit att skriva enillustrerad manual.För att finna orsaken till våra problem började vi med att genomföra en rad tester på motorn. Våradeduktiva och induktiva antaganden om vad som var fel i motorn grundade sig på dessa tester.Våra logiska slutsatser har dragits ur teoretiska resonemang och rent praktiska undersökningarav motorns inre delar och funktion. Det metodiska arbetet har begränsats till att på ett så logisktoch konsekvent sätt som möjligt lösa denna uppgift.
