In order to restore the information loss in video communication, a content adaptive intra error concealment method is proposed in this paper. Different images and different packet loss rates of the video sequences are used in the experiment. The experimental results show that the improved method has the better subjective quality and the higher PSNR than the bilinear interpolation and the semi-adaptive...
In this paper, we consider a class of time-delay artificial neural networks and obtain practical criteria to test asymptotic stability of the equilibrium of the time-delay artificial neural networks. These criteria require verification of the definiteness of a certain matrix, or verification of a certain inequality. The applicability of our results is demonstrated by means of a specific example.
In this paper, we consider a class of time-delay dynamical systems with nonlinear perturbation. The nonlinear perturbation functions are assumed bounded. we provide a robust stabilization criterion via designing a memoryless state feedback controller for the time-delay dynamical neural networks with nonlinear perturbation. The sufficient criterion is given in terms of linear matrix inequality (LMI)...
To track the state of charge (SOC) of Ni-MH battery pack at the hybrid electric vehicle, an artificial neural network (ANN) is designed. Current, voltage and the previous SOC are used to inputs of ANN, and output is SOC. The result show that, this artificial neural network can track the state of charge (SOC) of the batteries accurately, in the average tracking error less than 5%; the ANN is in low...
In this paper, we consider a class of time-delay dynamical neural networks with nonlinear perturbation. The nonlinear perturbation functions are assumed bounded. we derive a robust stability criterion independent of delay. The sufficient criterion is given in terms of linear matrix inequality (LMI). The checking for robust stability of time-delay dynamical neural networks with nonlinear perturbation...
According to meteorological element data of test reference year (TRY), a dynamic simulation program calculates the hourly cooling loads of an office building from April to September. Then, a general Visual Basic program is developed based on the error back-propagation (BP) algorithm of artificial neural network (ANN). The network is trained and tested by the obtained data. The results are presented...
In order to improve the identification efficiency of tag anti-collision algorithm in RFID system further, the improved framed slotted ALOHA algorithm is proposed with accurate tag estimation and quick identification, the whole process is divided into two phases including tag estimation and tag identification, in tag estimation algorithm, the collision probability threshold parameter is used to estimate...
A modified conformal technique for fourth-order finite-difference time-domain (FDTD (2, 4)) is proposed. This conformal scheme has higher-order accuracy than that of conventional FDTD and FDTD (2, 4) methods, which are caused by staircasing errors when modeling curved metallic objects. Two integration loops of Faradaypsilas law for the updating of magnetic field components are introduced here. Numerical...
In this paper, we primary focus on prolonging the network lifetime of wireless sensor networks (WSN), since the small, portable batteries integrated into the sensor chips can not be re-charged easily from an economical point of view. We first made a further analysis about the relationship between energy consumption and hop number. Then, an optimal hop number is deduced for minimizing the energy consumption...
