An experimental investigation of both confined and unconfined flames on a Triple Annular Research Swirler (TARS) is presented. The paper focuses on post-processing techniques aiming at extracting information on the dynamics that are lost through classical statistics approach. POD together with a derived a-posteriori phase averaging procedure successfully reconstructed the dynamics of flames under

By using metabolic engineering it is now possible to introduce new biosynthetic pathways or redirect already existing ones in a wide range of pro- and eukaryotic organisms. This thesis mainly addresses some approaches using metabolic engineering directed towards enhancing the stress tolerance in microorganisms and higher plants. The main approach employed in plants was to introduce the betA gene

Efficient scope management is a core part of software release management and often a key factor in releasing successful software products to the market. In a case when not all the requirements for the next software product release are known ‘a priori’ and when new requirements are issued throughout the project, the risk of overscoping by including more functionality than can be implemented increas

Large Eddy Simulation is used to study the flow behind a pair of symmetric backward facing steps. As reported in the literature, the flow exhibits an asymmetric pattern characterized by the deflection of the jet toward of the walls. The LES results are compared to LDA measurements showing the ability of the present numerical tool to capture the complex features of the flow. Furthermore, a sensitiv

Bildens roll i vetenskapen har skiftat med synen på vad vetenskap är. Det fanns en tid då bara det konstnärliga geniet ansågs kapabel att fånga sanningen i bild. Mot slutet av 1700-talet var det i stället sparsmakade grafiska illustrationerna som gällde; estetik ansågs leda till subjektiv förvillelse och blockera vetenskaplig kunskap. Med dagens digitala bildteknik har den vetenskapliga illustrati

The aim of this study has been to investigate the self-diffusion behaviour in polymer solutions and in surfactant solutions using the pulsed field gradient (PFG) NMR technique. The NMR self-diffusion experiment was shown to provide detailed information in complex surfactant mixtures. In particular, the microemulsion phase and the hexagonal phase of Didodecyldimethylammoniumsulphate (DDAS) formed

There is increased evidence to support the hypothesis that humanity actively, albeit inadvertently, contributes to global environmental change on a scale and with an intensity unprecedented in human history. Climate change, and to some extent stratospheric ozone depletion, present the international structures and systems for naturalresources management research and politics with fundamentally new

The age of parallelism is here. For a sustainable software development for massively parallel architectures the von Neumann model need to be replaced by one with native support for parallelism. We suggest a data flow model for signal processing applications. This will make it possible to reuse software implementations for different targets and future platform generations. We also outline our devel
