    Saab, Samer S.; Mhanna, Wassim; Saliba, Samir (2019-08-02)
    This paper examines the possibility for using RFID technology as a complete stand-alone vehicle positioning system. The concept is based on the vehicle carrying an RFID reader, which reads RFID tags installed on the side ...
  • Development of multivariable PID controller gains in presence of measurement noise 
    Saab, Samer S. (2019-07-23)
    This paper examines the ability of a multivariable PID controller rejecting measurement noise without the use of any external filter. The work first provides a framework for the design of the PID gains comprising of necessary ...
  • Differential GPS performance: ground versus geostationary satellite 
    Saab, Samer S.; Charbachy, Dany S. (IEEE, 2019-08-21)
    When GPS measurements are made by two users within the same GPS satellite transmission sight, the associated errors are mainly similar. Consequently, knowing the exact location of the receiver with respect to GPS satellites ...
  • Discrete-time Kalman filter under incorrect noise covariances 
    Saab, Samer S. (IEEE, 2019-08-09)
    The optimum filtering results of Kalman filtering for linear dynamic systems require an exact knowledge of the process noise covariance matrix Q, the measurement noise covariance matrix R and the initial error covariance ...

    Applies a discrete-time learning algorithm to a class of discrete-time varying nonlinear system. The author investigates the robustness of the algorithm to state disturbance, measurement noise and reinitialization errors. ...
  • Forecasting passenger load for a fixed planning horizon 
    Saab, Samer S.; Zouein, Pierrette P. (2016-02-18)
    This paper presents a forecasting system for predicting the number of boarding passengers on each of the next N departure dates of a particular flight leg using as input the booking levels made for the next N departure ...
  • A heuristic Kalman filter for a class of nonlinear systems 
    Saab, Samer S. (2019-07-31)
    One of the basic assumptions involved in the "optimality" of the Kalman filter theory is that the system under consideration must be linear. If the model is nonlinear, a linearization procedure is usually performed in ...
