Radiation source detection using a network of detectors is an active field of research for homeland security and defense applications. We propose Source-attractor Radiation Detection (SRD) method to aggregate measurements from a network of detectors for radiation source detection. SRD method models a potential radiation source as a “magnet”-like attractor that pulls in pre-computed virtual points...
In this paper, an extended linearized neural state space (ELNSS) model is proposed and used to design an approximate pole assignment control strategy for a class of nonlinear systems. At first, the applicability of the ELNSS model to approximate affine nonlinear systems is studied, where the extended Kalman filter (EKF) algorithm is employed to train the weights of the ELNSS model. It has been shown...
This paper presents a data transform method. It converts nautical test data of rotating modulation inertial navigation system (INS) at low latitude to navigation simulation data in polar area. The simulation data are used to verify the polar navigation algorithm of rotating modulation INS. The proposed method solves the problem which is difficult to reflect the process of rotating modulation or the...
Lyapunov Exponents (LEs) measure the exponential rates of divergence or convergence of nearby trajectories in state-space models. The study presented in this paper investigates the applicability of this concept to power system transient stability analysis. It is shown that the Largest Lyapunov Exponent (LLE) of the post-fault system subsequent to a given fault scenario is independent of the fault...
Solid oxide fuel cells (SOFCs) are modular and flexible in relation to the fuel in use, and have the capability to be used for combined heat and power applications at high efficiency. Due to the advantages, SOFCs are emerging as an attractive energy generation option. As a generation resource, SOFCs could be used as a distributed one connected with a large power system and also could be planted in...
The authors present an auto-calibration technique to estimate the directions-of-arrival (DOAs) of unknown signals in the presence of sensor gain and phase errors. Compared with other autocalibration algorithms, this algorithm is computationally more efficient and has a unique solution for a linear array with the imposed constraints. Furthermore, the complex computation in the objective likelihood...
