Bredband har de senaste åren gått från att vara en ovanlig företeelse till att i Sverige närmast ses som en mänsklig rättighet. En teknik som ger många individer tillgång till IT-infrastrukur med hög överföringskapacitet är trådlösa nätverk av typerna WiFi och WiMax. I uppsatsen konstateras att ett marknadsmisslyckande kan förekomma på privata marknader för trådlöst bredband. Detta marknadsmisslyckande analyseras utifrån teorier om externa effekter och kollektiva varor. De positiva externa effekter som trådlösa nätverk genererar ger varan drag av kollektivitet.

Business Intelligence may help organizations in making the right decisions byproviding data for analysis which can be presented to decision makers. DataWarehouse which is a central part of Business Intelligence can be built in severalways but the methods presented by Ralph Kimball and Bill Inmons are considered thetwo main methods. The solution provided by Inmon focuses on integrating the entirebusiness into one large database using relational database development. Kimballhowever proposes dimensional database modeling by creating one or more data martsand integrating these using a data bus. Previous research has shown that the quality ofa Data Warehouse can be measured through critical factors such as data quality andsystem quality.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Aitik-gruvan utanför Gällivare är en av Europas största koppargruvor. Malm bryts i dagbrott och släntdesignen bygger till stor del på undersökningar och karteringsarbeten från 1970- och 1980-talet. Idag når dagbrottet betydligt djupare nivåer jämfört med då dessa studier utfördes. Det var därför aktuellt med en ny undersökning för att avgöra om det råder liknande eller förändrade förhållanden beträffande spricksituationen i dagbrottet. I detta examensarbete utfördes sprickkartering med hjälp av digital stereofotogrammetri, i syfte att kartera nya blottade delar i dagbrottet.

The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

Inkorporering av extern data i datalager är problematiskt och problematiken bekräftas av aktuella undersökningar inom området. Detta har medfört att det utvecklats olika former av stöd för att bemöta och analysera problemen som organisationer ställs inför.För organisationer är det i högsta grad viktigt att dess beslutsfattare är välinformerade och klarar av att selektera information från stora mängder data. Det är i dessa sammanhang som en datalagerlösning är en viktig hörnsten för att stödja analys och presentation av data som ursprungligen är lagrad i olika datakällor (både interna och externa). Genom att inkorporera extern data i datalagret uppnår datalagret en betydligt högre potential och således kan även organisationer och framförallt dess beslutsfattare utvinna stora fördelar.Strand (2005) har tagit fram riktlinjer för att stödja inkorporeringsprocessen av extern data i datalager. Dock saknas en utvärdering av riktlinjerna.

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.

Campylopus introflexus is a moss species that originates from the southern hemisphere and has spread worldwide during the 20th century. Today it is classified as an invasive alien species in many countries, and it has been seen during inventories that it has become widespread in Sweden as well. The purpose of this essay is to contribute to new knowledge about how this moss affects species diversity on Calluna heathlands in Sweden. The study includes both fieldwork and an analysis of scientific literature on the subject, and the question that is answered is if C. introflexus has an impact on species richness in the heather peat.

The purpose of this thesis is to examine Skogsstyrelsens event Skogens Dag as an information channel by looking at information use and information behaviour during the communication process of the event. This is done by examining the aims of Skogsstyrelsens information distribution during the event in relation to its outcomes. The evaluation is focused on long term effects on the target group and it is restricted to Skogens Dag in Borås 2005. The question this thesis intends to answer is: How does the event Skogens Dag function as a tool for information distribution? The theoretical background gives an account of the communication process as well as the relevant aspects of marketing, social marketing, campaigns and public relations, as these are communication attempts that can use an event as a medium.

Utbetalningsbelopp för skadeersättning studeras. Datamaterialet uppvisar skevheter och ''tjocka svansar'' vilket motiverar att modellera med en mer flexibel fördelning än normalfördelning. I detta arbete undersöks om NIG (normal invers gaussisk) fördelning passar för det..

This essay is a study and analysis of the funnel beaker pottery at Gullarve 1:13 in Väte parish. The purpose of the study is to analyse the chronology of the settlement by determine the distribution, stratigraphic context and the ornamentation of the pottery. Another purpose is to discuss the geographical location of the settlement in the landscape.In this essay a short review of the pottery and the funnel beaker culture as well as a description of the pottery from the archaeological excavation from 1984 at Gullarve 1:13 is presented. Since the documentation of the archaeological excavation from 1984 is missing or is very inadequate, no spatial analysis can be carried out. The distribution of the pottery can?t contribute to the result of the essay, though if possible it probably would have provided some interesting results.

Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.
