  3. 2. Live VM Migration : Principles and Performance

    Författare :Petter Svärd; Erik Elmroth; Eric Jul; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Live Migration; Virtualization; business data processing; administrativ databehandling;

    Sammanfattning : Virtualization is a key technology for cloud computing as it allows several operating system instances to run on the same machine, enhances resource manageability and enables flexible definition of billing units. Virtualization works by adding a software layer, a hypervisor, on top of the hardware platform. LÄS MER

  4. 3. Recovery of Scandium using Antisolvent Crystallization in the Valorization of Scandium-containing Waste Streams

    Författare :Edward Peters; Kerstin Forsberg; Michael Svärd; Jens-Petter Andreassen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antisolvent crystallization; ammonium scandium hexafluoride; ammonium metal fluorides; phase equilibria; solubility; supersaturation; seeding; agitation mechanism; crystal size distribution; morphology; Chemical Engineering; Kemiteknik;

    Sammanfattning : Scandium is widely dispersed in the earth’s crust and is rarely concentrated in ores, and a viable option to guarantee a secure supply of scandium is to recover the metal from waste streams of other mining and metallurgical facilities. The valorization of such streams to recover metals of value is a prerequisite to alleviate the global shortages of scandium and other rare earth elements. LÄS MER
