Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

Undervisningen ska hålla hög pedagogisk standard och uppfylla de läromål som finns angivna i läroplanen. Tidigare forskning om populär kultur och lärande har bearbetats för att i analysavsnittet visa konkreta metoder för att uppfylla läromål genom att analysera ett populär kulturellt barnprogram..

I den här uppsatsen redogör jag för mitt arbete som C-foto på långfilmen Äta, Sova, Dö där jag jobbade i två månader under våren 2011. Man får följa min väg från förberedelserna jag gjorde inför filmen och mina tidigare erfarenheter i området, till hur det gick för mig på inspelningen. Jag beskriver även min undersökning av idéarbete och produktionsprocesser inom långfilmen ur mitt perspektiv. Jag visar två olika sätt man kan arbeta med idéarbete på film utifrån intervjuerna jag gjorde med regissören Gabriela Pichler för Äta, sova, dö och filmregissören Johan Lundborg på hans film Isolerad. Skildringar gör jag också via intervjuerna jag hade med produktionsbolaget AFOS och teaterregissören Kent R Andersson mot hur idéarbete fungerar under reklamproduktioner och teater. För att lättare visa hur arbetet i de olika produktionerna kan se ut har jag sammanställt produktionsprocesser för varje produktion steg för steg från idé till färdig produkt..

Sandvik har idag ingen standard för hur webbapplikationer ser ut på olika plattformar. Därför kan utseendet skilja sig mellan olika plattformar och de använder olika stylesheets för att forma designen. Uppgiften är att skapa en mall som ger samma resultat designmässigt oavsett vilken plattform som används. För att genomföra detta används olika utvecklingsmiljöer på olika plattformar. Skapandet av mallen utgår från intranätet och dess riktlinjer och de standarder som är aktuella idag kontrolleras..

There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.

The purpose of this paper was to examine the inflation hedging capabilities of property shares. A common notion is that property is a good hedge against inflation. Indeed, positive correlations have been found for direct investments and inflation. However, property shares are generally perceived as a perverse inflation hedge. This discrepancy has often been quoted as evidence of property shares divergence from the development of the underlying property market.

OpenGL is a standard API that is used to manage 3D graphics on desktop computers. Although OpenGL is independent of customized hardware it?s not suitable for all kinds of devices. Therefore both OpenGL ES andWebGL was created. These can be viewed as subsets of OpenGL.

The main purpose with this master's thesis was to develop a survey with the intention to examine what expectations the JM AB:s customer had on a future garden and also to discuss if the lawn has a symbolic meaning in gardens. The lion's share of the thesis is based on a survey, aimed at people in the company's customer database. The intention was to examine what expectations they had on their future garden and if their expectations were met when they later bought a house from the company. The work also consists of interviews and visits to areas with newly built homes. I interpreted the result from my surveys as the lawn on its own being is a strong symbol for a garden and also signals a social status of the owner. To the company the pre made lawn on a role is a way of saving time and easily achieve what the customer request. The company wants to create a concept of a "preset-garden" that meets the company's vision as well as the expectations of the customer.

This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.

AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.

Föreliggande uppsats syfte är att utreda huruvida Sverige är i behov av en moderniserad och mer internationellt anpassad avtalslag. För snart tjugo år sedan ratificerade Sverige den internationella köplagen United Nations Convention on Contracts for the International Sale of Goods, CISG, med reservation för konventionens del II om ingående av avtal. Detta eftersom Sverige tillämpar löftesprincipen vid ingående av avtal och CISG utgör en kompromiss mellan löftes- och kontraktsprincipen. Sverige är tillsammans med de övriga nordiska länderna ensamt om att reservera sig mot denna del och har därför av andra staters näringsliv kommit att ses som provinsiellt samt bakåtsträvande. Den globala handeln blir allt viktigare för Sverige och det svenska näringslivet har till följd av detta ställt krav på landets ledande makthavare att dra tillbaka reservationen och att anta den avtalsrättsliga delen.

 Dagens ekonomi är i mycket större utsträckning än tidigare inriktad mot tjänst och kunskapsintensiva organisationer, vilket har lett till en genomgripande strukturell förändring, det immateriella kapitalet är på väg att konkurrera ut de fysiska kapitalen. Därför är det viktigt att synliggöra denna förändring och anpassa redovisningen för att kunna skapa väl fungerade arbetsmetoder för företagen. Målet med redovisning är att redovisningen skall ge en rättvisande bild av företagets finansiella ställning. Vilka tillgångar som skall redovisas i balansräkningen för att ge en så rättvisande bild som möjligt är en svår fråga.Ett företags tillgångar kan vara både materiella och immateriella. Kraven för att få aktivera en utgift som en immateriell tillgång i balansräkningen är hårda.
