  1. 16. Centrifugal compressor flow instabilities at low mass flow rate

    Författare :Elias Sundström; Mihai Mihaescu; Håkan Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Centrifugal Compressor; Large Eddy Simulation; Internal Com- bustion Engine; Aeroacoustics; Modal Flow Decomposition;

    Sammanfattning : Turbochargers play an important role in increasing the energetic efficiency andreducing emissions of modern power-train systems based on downsized recipro-cating internal combustion engines (ICE). The centrifugal compressor in tur-bochargers is limited at off-design operating conditions by the inception of flowinstabilities causing rotating stall and surge. LÄS MER

  3. 17. Brand orientation in action : Towards a relational approach

    Författare :Johan Gromark; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Brand orientation; Brand co-creation; Market orientation; Transformational learning; Organisational narcissism; Brand orientation; Brand co-creation; Market orientation; Transformational learning; Organisational narcissism;

    Sammanfattning : Along with the ever-expanding interest in brands, the brand orientation concept has since its inception in the early 1990s steadily received more and more attention from scholars and practitioners alike. Brand orientation ultimately captures how organisations can develop sustainable competitive advantages in the form of brands. LÄS MER

  4. 18. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model

    Författare :Ebrahim Ghahramani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Homogeneous mixture model; Lagrangian bubble model; CFD; Cavitation; OpenFOAM; Multiphase flow; Hybrid model; Multi-scale;

    Sammanfattning : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. LÄS MER

  5. 19. Meteorological impact and transmission errors in outdoor wireless sensor networks

    Författare :Hjalmar Wennerström; Lars-Åke Nordén; Christian Rohner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Wireless sensor networks have been deployed outdoors ever since their inception. They have been used in areas such as precision farming, tracking wildlife, and monitoring glaciers. These diverse application areas all have different requirements and constraints, shaping the way in which the sensor network communicates. LÄS MER

  7. 20. Customer-geared competition : a socio-Austrian explanation of Tertius Gaudens

    Författare :Anders Liljenberg; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Ever since the inception of market economy, competition is the propellant of such economic systems. This is most notably so at present with global economies on the verge of a so called ‘new’ market logic. Competition nevertheless remains an elusive phenomenon, something holding true in particular when it is said to coexist with cooperation. LÄS MER
