IP-adresserna under IPv4 är inte tillräckliga och har på många delar i världen redan tagit slut. IPv6 erbjuder många fler tillgängliga adresser och övergången till protokollet har redan börjat. Det Gävlebaserade företaget Interlan erbjuder en tjänst som kontrollerar om kommuner och myndigheter i de nordiska länderna är nåbara via IPv6 samt om de är säkrade med DNSSEC. Denna rapport beskriver jobbet med att förbättra och göra deras tjänst anpassningsbar för flera länder. Processen som beskrivs är parametriseringen av skripten som samlar data, skapandet av en databas att lagra data i, och ändringar till hur data presenteras så att det går att lägga till flera länder..

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Examensarbetet har genomförts med utveckling och undersökning av signalbehandlingsalgoritmer för MEMS-gyron. Idag används många MEMS-gyron i olika elektronikprodukter. Företaget Motion Control utvecklar elektronik och inbyggd programvara och de har bland annat tagit fram MultiPos, som är en huvudmus för rörelsehindrade. MultiPos är en MEMS-gyro-baserad datormus. MEMS-gyron används för att känna av huvudrörelser som användaren gör, men det är önskvärt med en bättre signalbehandling, d.v.s.

Volvo Construction Equipment i Braås är världsledande inom tillverkning av ramstyrda dumprar. I Braås utförs därför en mängd olika testfall där man kartlägger utfallen genom insamling av data från CAN-bussar i dumpern. Om ett test går fel beskrivs det i en felrapport med tillhörande beskrivning av händelseförloppet. Idag finns det inget enhetligt sätt att visa händelse ihop med position.För att analysera insamlad data används idag CANalyzer. Fördelen är att det går att visa insamlad data på ett strukturerat grafiskt sätt.

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

Datorspelsbranschen är en relativt ung bransch, både jämfört med andra delarav mjukvaruindustrin och nöjesbranschen. En av de stora utmaningarnaspelutvecklare står inför är planeringen av den långsiktiga kompetensförsörjningen.Dock saknas sammanställda historiska data och applicerbararesursestimeringsmetoder, vilket gör detta arbete näst intill omöjligt. Det förstadelmålet med den här studien är att samla in historiska data angående strukturenoch storleken på utvecklingsteam som utvecklat AAA-spel (professionelltutvecklade spel med en hög budget) för pc-datorer. Datan samlas in frånkreditlistor hämtade via webbsidan Mobygames.com. Det andra delmålet beståri att utreda huruvida den insamlade datan kan appliceras på modeller förestimering av framtida personalbehov.

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

This paper is about finding out why minors are visiting pubs, and what it is that determines which pubs they opt to visit. To catch this, a qualitative approach is applied, specifically Fo-cus group interviews. There are interviews with a total of 10 informants. The informants come from two different schools in Gothenburg. There are six boys and four girls.

Ett program som simulerar signalbehandlingen i ett cochleaimplantat med signalbehandlingsstrategin ACE (Advanced Combined Encoder) har konstruerats. Programmets främsta syfte är att i förväg prova ut inställningar i ett cochleaimplantat och genom detta försöka förutsäga olika användares individuella inställningar. Programmet har validerats med utsignaler bearbetade av Cochlear Limited i deras egenkonstruerade Matlab-modul för forskning inom cochleaimplantat, NMT (Nucleus Matlab Toolbox). Samma insignal som använts av Cochlear Limited har processats av programmet och utsignalerna från detta jämfördes med utsignalerna från NMT. De bägge utsignalerna, producerade med samma inställningar, stämde bra överens. Komprimeringsfunktionen i programmet, som är en vital del av signalbehandlingen, visade sig stämma bra överens med NMT:s komprimeringsfunktion, sånär som på en relativ minskning av värdet vid starka insignaler. Programmet ska nu användas på Cochleaimplantat-sektionen vid Uppsala Akademiska sjukhus för att pröva ut individuella inställningar till användare av cochleaimplantat.

Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries.The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production.

AbstractThe aim of this study is to highlight the professional?s perspectives and work with young girls who have eating disorder anorexia nervousa. We assume a social constructivist perspective where the professional?s interpretations and perspectives on the issue anorexia considered. The study is based on a qualitative analysis of interviews with seven professionals in the areas of work, social services, school counselor, school nurse, anorexia unit and child and adolescent psychiatry (BUP).From a thematic analysis of the interviews, three themes emerged.

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Through this thesis I aimed to further investigate how we can adapt our western and modern views of masculinity and femininity in an ancient population, here on the Pitted Ware population from Ajvide on Gotland. A questionnaire survey was used to compile the modern view of masculinity and femininity. This modern view was then compared with patterns which had become visible through statistical processing of the burial gifts found on Ajvide. The thesis is mainly focused around the concept of gender, but age and status have also been discussed. Through several performed correspondence analysis, it became clear that the current view of male and female differed from the one that became visible in the archaeological record.
