  1. 1. Stochastic Chemical Evolution : A Study of Scatter in Relative Elemental Abundances in Extremely Metal-poor Stars

    Författare :Torgny Karlsson; Bengt Gustafsson; Mike Edmunds; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; nucleosynthesis; chemical evolution; Galactic evolution; supernovae; chemical abundances; Population II stars; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik;

    Sammanfattning : Chemical evolution addresses the problem of the formation of the chemical elements and their evolution throughout the history of the universe. This thesis discusses in particular the chemical evolution in the young universe and what we may learn from the observations of the oldest stars. LÄS MER

  3. 2. Autonomous cloud resource provisioning : accounting, allocation, and performance control

    Författare :Ewnetu Bayuh Lakew; Erik Elmroth; Hiaohui (Helen) Gu; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; distributed infrastructure; monitoring; accounting; performance modeling; service differentiation; business data processing; administrativ databehandling;

    Sammanfattning : The emergence of large-scale Internet services coupled with the evolution of computing technologies such as distributed systems, parallel computing, utility computing, grid, and virtualization has fueled a movement toward a new resource provisioning paradigm called cloud computing. The main appeal of cloud computing lies in its ability to provide a shared pool of infinitely scalable computing resources for cloud services, which can be quickly provisioned and released on-demand with minimal effort.

  4. 3. Secure Service Provisioning in a Public Cloud

    Författare :Mudassar Aslam; Mats Björkman; Christian Gehrmann; Ben Smeets; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; VM migration; trusted platforms; cloud security; IaaS; TPM; Security; Trusted Computing; Virtualization; Cloud Computing; trust; Computer Science; datavetenskap;

    Sammanfattning : The evolution of cloud technologies which allows the provisioning of IT resources over the Internet promises many benefits for the individuals and enterprises alike. However, this new resource provisioning model comes with the security challenges which did not exist in the traditional resource procurement mechanisms. LÄS MER

  5. 4. Architectural Evolution of Intelligent Transport Systems (ITS) using Cloud Computing

    Författare :Robayet Nasim; Andreas Kassler; Anna Brunström; Franz J. Hauck; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ITS; cloud computing; OpenStack; virtualization; asynchronous communication; publish subscribe system; scalability; distributed architecture; QoS; latency.; Computer Science; Datavetenskap;

    Sammanfattning : With the advent of Smart Cities, Intelligent Transport System (ITS) has become an efficient way of offering an accessible, safe, and sustainable transportation system. Utilizing advances in Information and Communication Technology (ICT), ITS can maximize the capacity of existing transportation system without building new infrastructure. LÄS MER

  7. 5. Bringing Visibility in the Clouds : using Security, Transparency and Assurance Services

    Författare :Mudassar Aslam; Mats Björkman; Christian Gehrmann; Chris Mitchell; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cloud Security; Trusted Computing; Trustworthy Clouds; Cloud Audits; Security Automation; SCAP; Virtual Machine; Computer Science; datavetenskap;

    Sammanfattning : The evolution of cloud computing allows the provisioning of IT resources over the Internet and promises many benefits for both - the service users and providers. Despite various benefits offered by cloud based services, many users hesitate in moving their IT systems to the cloud mainly due to many new security problems introduced by cloud environments. LÄS MER
