Under de senaste årtiondena har matematikbokens format inte utvecklatsnämnvärt, man har försökt att blir mer digital genom att skickamed en cd-skiva med digitalt material och för de lägre årskurserna igrundskolan finns det matematikspel. För gymnasielever finns inte mycketinteraktivt och digital material idag. Behovet av en ny lärresurs ärstort och vi vill med detta arbete utröna vilka funktioner som bör ingå.Elever och lärare är överlag mycket positiva till utvecklingen ochde undersökningar vi tagit del av visar på ökat användande av datorerute på skolorna. Vi tog fram två gränssnittsskisser med en lärargruppoch en elevgrupp oberoende av varandra. Dessa två skisser sammanfogadestill en prototyp.

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.

Digital video är ett område som expanderat kraftigt senaste åren. På grund av avancerade videokompressionsmetoder kan numera en hel långfilm rymmas på mobiltelefonen eller den handhållna videospelaren. Men hur fungerar videokompression och hur hårt kan man komprimera en viss filmsekvens med bibehållen användarnytta? I denna uppsats görs en genomgång för grunderna inom videokompression. Dess förhållande till användarnyttan undersöks genom ett experiment.

Som en effekt av att Video On Demand (VOD) är på stark tillväxt vill June, som en leverantör av mjukvara för TV-branschen, förvärva kunskaper och utvärdera Windows 8 applikationer som plattform för en VOD-tjänst. June har sedan tidigare en webblösning för VOD och vill nu även jämföra och utvärdera bland annat kunskapskrav, tidsåtgång samt fördelar och nackdelar med en Windows 8 applikation ställt mot denna webblösning.Målen med examensarbetet kan delas in i tre delar; en där komplexitet och arbetsinsats vid Windows 8 applikationsutveckling utvärderas, en där verktygen som krävs för att utveckla en VOD-applikation utvärderas och sist att implementera en Windows 8 applikation för VOD.En Windows 8 applikation utvecklades och valda lösningsmetoder dokumenterades. Dokumentation och kunskap som förvärvats under utvecklingsfasen stod sedan som grund för de analyserande och utvärderande målen. Resultatet är en Windows 8 applikation som uppfyller de mål som satts upp för programmeringsdelen samt en analys och utvärdering som svarar mot målen för analysdelen. Ämnen som är centrala genom rapporten är Microsoft, WinRT, VOD, Smooth Streaming, PlayReady, Windows 8 applikationsutveckling samt data caching och utveckling av användargränsnitt i Windows 8..

Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.

The concept of IT has developed into ICT (Information- and Communication Technology) over the years. ICT has an increasing impact in society and the Swedish curriculum (Lpo 94) highlights the importance of school to convey lasting knowledge that constitutes the general frame of reference that everyone in society is in need of. The purpose of this study was to find out how teachers perceive and use ICT in secondary school and discover the teachers? vision concerning ICT.The used approach for the study is a qualitative research with a basis of interviews. Four interviews are made with teachers from the early years of secondary school, at two different schools.

The objective of this study was to make an inventory and a potential analysis of the organic beef production in the region of Gävleborg, Sweden. A survey was conducted, where a questionaire was sent to all farmers in the region who had environmental subsidies concerning organic cropping systems in 2001. In total, there were 701 farmers, of which 46 % participated in the study. Three slaughter houses were interviewed to get their pictures of the development of organic beef production. The study shows that there are potentials and interests in the region to increase the production of organic beef.

This paper works as an assignment from the Video On Demand Company Headweb, who wanted aninterface analysis of their own and their competitors VOD services. The purpose is to help Headwebwith their own interface by studying theirs and others interfaces and make an analysis on how theyfunction, how they look and how good the usability is with every service, with hope to findsomething that could make the VOD service of Headweb better.I have also studied how the interfaces of the VOD services look on different platforms, to see howthey are designed as a whole. This has been an expert analysis where I have studied the differentVOD-services by myself, without any external users.To find advantages and disadvantages with the services and their platforms, I have used differenttheories, models and design patterns to frame areas such as filmsearch, categorization, registrationand navigation. I have compared the VOD services with each other and drew conclusions for eacharea to see how the interfaces differ between the services, but also between platforms.My analysis has shown that all VOD services in this project have a very unique interface, eventhough they all have the same goal, to allow the user to control their viewing of film. They usevarious functions and structure and use their own page names and categorizations.

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

With a shifting world market and periodically profitability issues, Swedish farmers seekalternative ways to enhance their profitability. One interesting alternative to get a highervalue and enhance products is biodiesel, a way to improve the profitability on a farmscale.The diesel that is produced and sold, already have a mixture of 5% biodiesel, andthere is a possibility to add more biodiesel to it. By developing new engines severalengine-manufacturers now allow a mixture up to 100% biodiesel in their engines. Hencethere is a market for an increased production of biodiesel. The aim of this study were toinvestigate the possibilities and the problems related to farm-scale production ofbiodiesel, and to study the profit margin in the production.

The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.
