    Adaptive Estimation of Satellite Attitude via an Entropy Approach

    , M.Sc. Thesis Sharif University of Technology Barzegar, Aylin (Author) ; Pourtakdoust , Hossein (Supervisor) ; Kiani, Maryam (Supervisor)
    Abstract
    Nonlinear state estimation algorithms developed based on Bayesian framework have been increasingly utilized in space navigation and attitude estimation to enhance the mission performance. However, successful implementation of these algorithms requires accurate knowledge of process and measurement noise statistical properties. As the satellites experience various systematic and environmental uncertainties on orbit, no priori information of noise characteristics is usually available. In this regard, adaptive estimation algorithms have been widely utilized to tune the planned noise properties according to the variable working conditions. Among various adaptation methods, innovation-based...

    A Framework For Developing Corporate Innovation Strategy; PATSA Group Case Study

    , M.Sc. Thesis Sharif University of Technology Tajeddin, Hamed (Author) ; Kermanshah, Ali (Supervisor) ; Isaaei, Mohammad Taghi (Supervisor)
    Abstract
    There has been a lively debate between two major strategist groups in innovation strategy literature. The first, with Ansoff being the protagonist, pose a rational approach in describing a corporate innovation strategy formulation process while the other group, with Mintzburg as the protagonist, prescribe an incremental approach.It seems that in continuous change and uncertainty, rational approach can weakly predict the reality and one can claim that in such situations incremental approach is more effective than rational approach. Based on the review of literature and consequent classification, most of the strategies that are named as innovation strategies in literature use rational...

    Statistical Interpolation of Non-Gaussian AR Stochastic Processes

    , M.Sc. Thesis Sharif University of Technology Barzegar Khalilsarai, Mahdi (Author) ; Amini, Arash (Supervisor)
    Abstract
    white noise or an innovation process through an all-pole filter. Applications of these processes include speech processing, RADAR signals and stock market data modeling. There exists an extensive research material on the AR processes with Gaussian innovation, however studies about the non-Gaussian case have been much more limited, while in many applications the asymptotic behavior of the signal is non-Gaussian. Non-Gaussian processes have an advantage over Gaussian ones in being capable of modeling sparsity. Assuming an appropriate non-Gaussian innovation one can suggest a more realistic description of sparse signals and predict their behavior or estimate their unknown values successfully....
