Kommuner och myndigheters DNSSEC och IPv6 status

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..

Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner

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.

Mätning, Modellering och Presentation av Testvägar för Fordonsindustrin

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.

Datorspelsbranschen - Att estimera resursbehovet för nya projektteam baserat på historiska data

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.

Utveckling av dataanalysprogram för Opcon Powerbox

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.

Smart plombering och märkning

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Metodfokus på Affekt; Hur känns det?

Evidence-based psychotherapeutic methods compete with each other, while meta-analysis have shown that variability due to different methods related to outcome is remarkably low. In this qualitative study six former patients were interviewed about experiences of method and technique in Affect-focused therapy, with a slight overweight towards unsatisfactory experiences. Responses were analysed and categorised in emergent themes. Methodological focus on affect showed to be a much appreciated, as well as insufficient, element. Alongside positive experiences or summaries of therapy, methodological frames were felt to be at times restrictive, even invalidating, as far as not allowing focus on what was felt to be the more predominant need.

Sveplaserns användning till inventering/befästning/kontroll av vägmarkering

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

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.

Inmatningsrutiner för interna metadata i GISMeta

Metadata är en viktig del i arbetet med geografiska data. Med bra metadata kan användaren på ett enklare och effektivare sätt hitta de data som är intressant för just honom eller henne. Länsstyrelsen i Västmanland har stora mängder geografiska data och beslutsdokument som rör geografiska områden. Dessa geografiska data och dokument lagras på servrar och är tillgängliga för handläggarna (användarna). GIS-gruppen har tidigare lagrat metadata för dessa geografiska data i en databas uppbyggd i Microsoft Access men en nyutvecklad metadatabas, GisMeta, ska börja användas.

Outsourcing av UAS-data : Informationshantering av data insamlad viaUAS

This reports purpose is to give a general view on how to handle information collectedthrough photogrammetry and laser scanning with the help of UAS. The report ismade in collaboration with WSP Group and will briefly describe howphotogrammetry and laser scanning, also known as Lidar, works and how those areused in the construction business today. Then the focus will be on how gathered datais handled today, how outsourcing of data should be approached and if there are anyconsequences if data is handled in the wrong way. Interviews have been made with allparts in the UAS business. That includes authorities as Transporstyrelsen,Försvarsmakten.

Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data

A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Webfarming : En studie av möjligheter och problem

För att företag skall kunna konkurrera på ständigt föränderliga marknader krävs att de har kunskap om exempelvis kundbehov, konkurrenter och nya produkter. Källor till denna kunskap finns både internt inom organisationer och externt i deras omgivning. Både de interna och externa kunskapskällorna är viktiga, men under de senaste åren har ett allt större intresse riktats mot de externa källorna, då de har blivit allt viktigare för att organisationer effektivt skall kunna hantera sina affärsprocesser.En av de kunskapskällorna som ofta nämnts är Internet och den data som lagras på hemsidor runt om i världen. Dock är det svårt att hitta relevant data på Internet på grund av dess omfattning och dynamiska karaktär. Det har därför börjat uppkomma nya tekniker för att inhämta, strukturera och integrera data från Internet.
