När datatrafik färdas genom ett nätverk så passerar det routrar och switcharsamtidigt som dessa enheter visar åt vilket håll paketet ska skickas. Detta kallas förrouting. För att paketen ska hitta rätt väg så använder man sig av routingprotokoll,som vägleder trafiken dit de ska, och olika protokoll har olika fördelar samtidigtsom de används vid olika tillfällen. Målet var att skapa ett stort enhetligt nätverksom tål höga belastningar, har en hög uppkopplingsprocent samtidigt som det skavara lätt att expandera i framtiden. Det största problemet var hur trafiken färdasmellan varje kontor, men problem som hur användarna ska vara uppkopplade tillInternet tas upp i rapporten.

Under fem veckors tid har jag utfört mitt examensarbete på Facebook Data Center i Luleå. Målet med arbetet var att installera ett internt nätverk som skulle ersätta ett annat internt nätverk. Bakgrunden till arbetet är att nätverket som redan existerade i datacentret (innan bygget överlämnades till Facebook i Luleå) hade en omodern nätverksstruktur. I arbetet avsattes tid till inläsning av plattformarna för routrar och switchar. Dessa enheter monterades senare upp i respektive rack.

  During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.

Active environmental activity?? a comparative study of the municipalities environmental activityThesis in Political Science D-Level at Karlstad University byJenny Ljung Spring 2008Tutor: Michelle MichelletiThe threat against our climate is one of our biggest challenges today. The awareness of the problem has grown rapidly for the last years in governments on international, national and regional level. The Swedish government is recognized as one of the leading countries in the climate and environmental work internationally. The Swedish municipalities play a big role in this successful work.

Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).

Målet med studien har varit att ta reda på hur man med hjälp av IT kan stödja enimplementering av IT-baserad planering inom transportbranschen, mer specifikt ruttplaneringsamt se vad som krävs för att reducera den stora mängd komplexitet som omger den. I fleraartiklar från Computer Sweden diskuteras det att man med hjälp av IT-stöd kan minskakostnaderna, öka inkomsterna och arbeta på ett mer klimatsmart sätt. För att få kunskap omområdet har Gayialis och Tatsiopoulos artikel Design of an IT-driven decision and supportsystem for vehicle routing and scheduling använts som kunskapskälla och som ett anpassatteoretiskt ramverk efter vår studie. Vidare har litteraturstudier utförts inom logistikområdet.För att bygga upp en empiri har en kvalitativ intervju genomförts samt en undersökning avbranschanpassade IT-lösningar. Resultatet av datainsamlingen blev en punktlista på komplexaparametrar som måste hanteras av den undersökta transportorganisationen för att uppnåeffektiviseringsvinster med hjälp av IT-baserad transportplanering.

The company Västra Mälardalens Kommunalförbund, VMKF, wishes to revise and optimize their present data and IP-telephony network as of today consists of the three municipalities Köping, Arboga and Kungsör. As a municipal corporation, they seek consultation regarding internal as well as external review and investigation of the main structure of the network, its functionality and safety. By today?s increasing demands of Internet accessibility, availability of services and security far more extends the requirement of a complete network design. The foundation of networking rests on the balance between each of these necessities.

Marketing communications have earlier been conducted via traditional channels. Today companies have discovered the possibility of doing much of their marketing communication in cooperation with the web at relatively low cost. This development has led to the ability for small businesses to compete with large companies independent of geographic location. The purpose with this thesis was to examine how small businesses use their website in marketing communications with their customers in the consumer market. In order to reach this purpose we have conducted interviews with five small businesses in different business trade with varying degrees of website usage, located in Piteå and Luleå.

?Are the headwaters streams at the right position in the map? is a study that has been performed on behalf of Holmen Forest, region Örnsköldsvik. This study will be the basis for deciding if the Hydrology Layer Property map or Holmen Forest map will be used for planning nitrogen fertilization in forestry. The background to this study is that nitrogen fertilization near water will increase the risk of nitrogen leaching out into the water systems, which has a negative impact on the environment. The headstreams positions have been recorded in the field with a GPS and the data analyzed in the geographic information system ArcMap.

The study was carried out as a time study of five wood chippers placed on trucks,so?called huggbilar. They are trucks with built?in wood chipper, chip bowl and crane pulling a chip trailer. The system is used for chipping wood fuel, transporting, and delivering the chips to heating plants.

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

I takt med Försvarsmaktens ökade engagemang internationellt och det faktum att alla insatsförband inom Försvarsmakten ska kunna verka på alla konfliktnivåer och i en urban miljö kommer nya krav och behov på bekämpningsförmågan att uppstå avseende precisionsbekämpning.Med hjälp av ett GIS kopplat till EOI:et vid en insats i en urban miljö kan en rad vinster erhållas för att stödja artilleriet vad avser precisionsbekämpning. Exempel på sådana områden är: målverifiering, justering av målkoordinater, lägesuppfattning avseende målets närmiljö, redovisning och presentation av verkansområde inför en insats för dimensionering av verkan..
