  1. 1. Emerging Paradigms in the Convergence of Cloud and High-Performance Computing

    Författare :Daniel Araújo De Medeiros; Ivy Bo Peng; Stefano Markidis; Pawel Herman; Valeria Cardellini; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-performance computing; Kubernetes; airflow; elastic scaling; MPI; S3; Datalogi; Computer Science;

    Sammanfattning : Traditional HPC scientific workloads are tightly coupled, while emerging scientific workflows exhibit even more complex patterns, consisting of multiple characteristically different stages that may be IO-intensive, compute-intensive, or memory-intensive. New high-performance computer systems are evolving to adapt to these new requirements and are motivated by the need for performance and efficiency in resource usage. LÄS MER

  3. 2. Resistance breathing with PEP and CPAP : effects on respiratory parameters

    Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

    Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER

  4. 3. Efficient and environment-friendly combustion of biomass in bakery oven furnaces

    Författare :Fabiao Manhica; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; flow pattern; temperature profile; airflow; bread quality; Wood-fired bakery oven WFBO ;

    Sammanfattning : AbstractCombustion of biomass in small-scale furnaces is widely used in many countries and in different applications. Often, the technology used is fixed grate combustion in small batch furnaces. LÄS MER

  5. 4. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

    Författare :Liang Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

    Sammanfattning : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique. LÄS MER

  7. 5. Efficiency of a wood-fired bakery oven - Improvement by Theoretical and Practical
