Data warehouse system är något som har växt fram under 1990-talet och det har implementeras hos flera verksamheter. De källsystem som en verksamhet har kan integreras ihop med ett data warehouse system för att skapa en version av verkligheten och ta fram rapporter för beslutsunderlag. Med en version av verkligheten menas att det skapas en gemensam bild som visar hur verksamhetens dagliga arbete sker och utgör grundinformation för de framtagna analyserna från data warehouse systemet. Det blir därför väsenligt för verksamheten att de framtagna rapporterna håller en, enligt verksamheten, tillfredställande god datakvalitet. Detta leder till att datakvaliteten hos data warehouse systemet behöver hålla en tillräckligt hög kvalitetsnivå.

Uppsatsen bygger på en analys av en exit-nod i Tor-nätverket i syfte att efterlikna ett tidigare experiment från 2007. Experimentet går ut på att analysera den information som kommer genom nätverket för att leta efter okrypterade lösenord. Experimentet görs i syfte att påvisa de brister som finns i nätverket och i användarnas säkerhetsmedvetande. Arbetet utgår från frågeställningarna:Går det att utvinna känslig information från en exit-nod i Tor-nätverket.-       Går det att utvinna okrypterade lösenord från en exit-nod i nätverket?-       Vilka typer av tjänster tillhör lösenorden som uppkommer i analysen av den insamlade data?För att kunna besvara mina tre frågeställningar har jag valt att göra ett experimentellt arbete för att ta reda på om användarna skickar okrypterade lösenord, och till vilka tjänster lösenorden tillhör.

Målet med detta arbete har varit att undersöka potentialen för skördardata (pri-filer) när det kommer till prognostisering av sortimentsutfall från avverkningar. Det gjordes genom regressionsanalys, där data från Sveaskogs beståndsregister utgjorde de förklarande variablerna och data från pri-filer utgjorde responsvariablerna. Arbetet hade i huvudsak tre analysmoment: undersökning av beståndsregistrets noggrannhet, samt hur väl arbetets prognoser stod sig mot facit (pri-filer) och dels mot Sveaskogs egna prognoser via VALS. Totalt utgjordes data av 42 trakter med tillhörande beståndsdata innan avverkning och de traktspecifika pri-filer som skapades under avverkningarna. Det påvisades avvikelser, stundtals stora avvikelser, mellan beståndsregistret och pri-filer. Avvikelserna redovisades inte per hektar, p.g.a.

The purpose with this thesis is to clarify how estate agents working with their marketing and marketing strategies. Our study has occured in Kalmar and we have used five different estate agents for our collection of empiric?s data. We have worked with a qualitative methodology to achieve deeper knowledge about these five company?s which have been chosen for the study.We have selected theories that suit our subject and together with the empiric data these two parts will be compared which concludes in an analysis.

The purpose of this study is to investigate how much of the estimated annual electric energy production from Swedish wind power that actually was produced, as well as the history of this agreement over time. The aim is to also examine if there are properties that have caused some group of wind power plants to produce more or less, compared to their estimated production. Operational data on wind turbines collected by the Swedish Energy Agency was analyzed. A survey was made among owners of wind power plants with a nominal power of at least 2 MW. Two different methods for normal year correction of production data were used and compared.

CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.

Resulting from anthropogenic carbon dioxide emissions, average surface seawater pH is estimated to decline from today's approximately 8.05 to between 7.78 and 8.03 towards 2100. For ionisable organic pollutants, changes in pH can lead to a change in the degree of ionisation, which could influence the ecotoxicity of a compound by altering its bioavailability. In this study, potential changes in ecotoxicity of ionisable organic compounds resulting from ocean acidification are examined. This is achieved partly by conducting a literature review, analysing existing literature that investigates this relationship. Potential changes are also evaluated by examining marine ecotoxicity data for ionisable organic compounds on the watch list pursuant to Directive 2008/105/EC of the European Parliament and of the Council, as well as on the list of priority substances according to the 2022 proposal for amending the Water Framework Directive (2000/60/EC).

Purpose: The purpose of this study is to find out how much influence underlying factors have in connection to the internationalization of Born Global firms. Methodology: This study has a qualitative approach in which data is obtained mainly through interviews and secondary data which consists previous theories about the internationalization in small and medium sized firms and recent theories that entitle these firms as Born Global. Conclusion: Based on the existing theories and the qualitative data, we have concluded that the underlying factors for the Born Global firm?s internationalization are abilities and opportunities to create insidership in relevant networks. The most crucial underlying factors for Born Global firm?s internationalization are the ability to create processes to break old patterns of thoughts and the ability to ally with right partners. .

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

This basic data of knowledge for a future maintenance programme concerning the park at Kungsholmen is made up of 3 separate parts. 1.) A historical documentation 2.) A mapping and documentation of the objects status of today. 3.) An analytical evaluation complemented by a maintenanceproposal for the historic park. The aim of the document is to serve as a future basic data for decision making, based on the aim to preserve and develop the described cultural values of the object. The different parts can be used separate or altogether in order to define or redefine new goals..

Previous research has discussed how voluntary disclosure relates to the cost of equity capital. Theories of estimation risk support a negative association between disclosure and cost of equity capital, as empirically documented by Botosan (1997) among others. In this Bachelor thesis we investigate whether such a relationship exists on the Swedish capital market. Using the CAPM to estimate the cost of equity capital and a disclosure index based on Aktiespararen?s annual evaluation of corporate disclosure, we test a model where disclosure explains cost of equity capital.

Syftet med studien har varit att undersöka möjligheten att skapa en enkel modell att undersöka optimal hantering av avfall i Sverige. Den modellen skulle i så fall ingå som en del i ett regerings uppdrag om det är möjligt att sätta upp ett nationellt miljömål mot ökat effektivt användande av resursen som avfall utgör. Studien har utförts på uppdrag av Naturvårdsverket inom ramen för examensarbete inom civilingenjörsprogrammet i kemiteknik på KTH.Inledande genomfördes ett antal intervjuer för att skapa en god bild av hur avfalls Sverige ser ut och inom vilka områden det finns potential för optimering. Sedan studerades artiklar, böcker och rapporter samt en stor mängd statistik som tillhandahölls från Naturvårdsverket samt RVF undersöktes. En bild av hur modellen skulle behöva se ut togs fram.

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
