To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.

Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

Today?s society has become more and more digitalized and we have access to more information than ever before. This has had a major impact on organizations and their work processes. For example have intranets become a common technical groupware to communicate and get relevant information from inside the organization. A common problem related to this is an over-reliance on the technology, where there's not taking into account that some informal and communicative means are difficult to occur through digital resources.The aim of this study is to examine the use of an intranet in a municipality, which consists of many different employees with various work situations.

This master thesis is a part of the DySCAS project at ENEA. The purpose of this thesisproject is to add support for streaming media and USB support to the DySCAS demonstratorplatform.To achieve this, some of the widely used middlewares available today were studied. The onethat proved to be of most interest is CORBA. Although CORBA?s solution to streamingmedia couldn?t be used due to their use of object programming, the CORBA solution didprovide some interesting thoughts regarding how the USB devices should be handled, in thiscase their ?resource inspector? and ?trading service?.Ethernet was the chosen network to support streaming media.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

To be able to maintain an adequate ITservice for various users and needs,more municipalities are looking at thepossibility for mergers of local ITdepartments. One solution for mergingmultiple services/functions and creatingsynergy opportunities is called SharedService Center (SSC). The concept of SSCis that the administrative serviceitself becomes a core activity withinthe organization. The aim of this thesisis to provide municipalities who areconsidering a merging of their local ITdepartments with recommendations on howto design the Shared IT Service Center.Recommendations are outlined based on ananalysis of IT-management literature,reports and by conducting a study onthree ongoing collaborations.The conclusions drawn from the studysuggest guidelines for the design of aShared IT Service Center formunicipalities. These are as following:Create a vision associated with aspecific and structured target state.Identify needs for different targetgroups in municipalities and set acommon standard.Create a clear and practical model/SLAappearance of the cooperation andagreement.Ensure the individual municipalitiescommissioning skills in order to notlose it in the context of a common IToperation.Find an organization that is democraticfor member municipalities andfacilitates long-term partnership.Specify the operation and maintenance sothat it can be regulated and controlledEstablish a common help desk.Establish a common standard andconsolidated infrastructure before theintroduction of a common technology platform..

The students have been assigned a task from Consid, were they are supposed to develop a web based platform for handling the company?s consult CV:s. The key features of the system are to simplify the administration part at mission procurements towards customers and to match qualified consultants to certain missions.Consid is an international it-consult company and have about 1000 consults working for them. When Consid makes mission procurements towards a customer they have to manually match the best consult against a certain mission, this is both time consuming and complicated.The students started the project with big visions and thoughts about how the work would be performed and how the system would be developed. After the initial meetings and the closer it came to the beginning of programming it became clear that the expectations were too big.

Kärnkraftverk är högteknologiska system med hög komplexitet och utan att hantera den här komplexiteten kan små olyckor få katastrofala följder. Närvaron av komplexitet försämrar förmågan att förstå situationer, minskar kontroll samt ökar risken för incidenter. Stabsarbete inom kärnkraftsdomänen kräver ett agilt beteende för att hantera den höga närvaron av komplexitet. Agilitet är förmågan hos en enhet att framgångsrikt genomföra, hantera och/eller utnyttja förändrade omständigheter. Syftet med arbetet är att utveckla ett mätverktyg för att identifiera indikatorer på agilt beteende i stabsverksamhet inom kärnkraftsdomänen.

The Swedish forest policies have earlier mainly been focused on two goals: production and environment. The production goal aims to benefit the economical gains from forestry while the environmental goal primarily aims to shield the ecological values of the forest. With the introduction of the Swedish environmental code and the environmental objectives it was made clear that the overall objective for Swedish community development, including the forestry sector, is sustainable development. Sustainable development includes supporting economic, ecologic as well as social values of which the latter seems to have been forgotten in the forestry sector. This was recently brought to attention to the sector and the debate how to handle the social values is now ongoing.The legislator has not been unaware of the social values since they have since long been at least somewhat included in the preliminary works.

The rise of social media has created an endless source of possibilities for companies to interact and connect with their target audiences. As it is a new channel, companies may experience uncertainty on how to use it to its fullest potential.The purpose of this study is to describe how the Public Service radio channel, P4 Kalmar, use its Facebook page and how its members perceive the communication on this platform. We have also presented recommendations on how P4 Kalmar can improve the relationship with its members. To reach our conclusions we have combined theoretical references with a quantitative content analyze, a survey and qualitative depth interviews.By analyzing our findings we came to the conclusion that P4 Kalmar have to develop a strategy for communicating on social media. But since no general communication strategy for the organization exists they have to develop one before developing one for social media.

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing.
