  1. 1. Modeling and identification of nonlinear and impulsive systems

    Författare :Per Mattsson; Alexander Medvedev; Roy Smith; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear system identification; modeling; impulsive systems; impulse detection;

    Sammanfattning : Mathematical modeling of dynamical systems plays a central roll in science and engineering. This thesis is concerned with the process of finding a mathematical model, and it is divided into two parts - one that concentrates on nonlinear system identification and another one where an impulsive model of testosterone regulation is constructed and analyzed.

    Sammanfattning : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. LÄS MER

  7. 5. Control Strategies for Improving Cloud Service Robustness

    Författare :Jonas Dürango; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis addresses challenges in increasing the robustness of cloud-deployed applications and services to unexpected events and dynamic workloads. Without precautions, hardware failures and unpredictable large traffic variations can quickly degrade the performance of an application due to mismatch between provisioned resources and capacity needs.
