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.

The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

Strukturell avbildning med ultraljud kan användas för att upptäcka sjukdomar och störningar i kroppen. För att ställa tillförlitliga diagnoser räcker det inte alltid med en strukturell avbildning utan ibland krävs det även fysiologisk information. Vid användning av funktionell avbildning med ultraljud kan den informationen mätas i kroppens olika fysiologiska system. Systemen består av funktionellt olika enheter och kallas för motoriska enheter i skelettmuskulatur. Vid sjukdomar som ateroskleros (åderförkalkning) kan dessa enheter vara så kallade kärlplack, som består av vävnad med varierande egenskaper och medicinsk relevans. Möjligheten att kunna analysera funktionella enheter i system som dessa kan bidra mycket till diagnostisering av sjukdomar och störningar. Den här studien presenterar en metod för att hitta naturliga kluster av funktionella enheter i skelettmuskulatur, från 3D-data inhämtat med ultraljudssekvenser. I studien genererades syntetiska data från en modell som simulerar sekvenser av aktionspotentialer i kontraherande muskelvävnad.

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.

An increasing number of automotive supplier companies are investing in Central and Eastern Europe (CEE) in order to gain cost advantages. This has happened in a rapid pace since many of these countries did not have any foreign direct investments (FDI) at the turn of the century. The problem now is for how long these countries will be able to maintain the low costs. One purpose was to create a model of country advantages for automotive supplier companies when relocating further production to CEE. This dissertation was written in cooperation with the Trelleborg Group.

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.

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.

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

En fallstudie tillämpades för att undersöka de inbyggda apparna, Internet Explorer 10, den nya utforskaren File Explorer och reparationsverktyget ?Återställ datorn utan att ta bort filer? i Windows 8. Analysen visade att apparna E-post, Kontakter och Meddelanden sparade större delar av användarens Facebook-profil lokalt på datorns hårddisk. När bildfiler öppnades upp med appen Foton sparades miniatyrbilder av originalet på hårddisken. När videofiler spelades upp med appen Video sparades filnamnet i filer.
