    This paper investigates methods of value-at-risk (VaR) estimation using extreme value theory (EVT). It compares two different estimation methods, “two-step subsample bootstrap” based on moment estimation and maximum likelihood estimation (MLE), according to their theoretical bases and computation procedures. Then, the estimation results are analyzed together with those of normal meth... View full abstract»

    Environmental stress screening (ESS) is a technological process to reduce the costly early field failure of electronic components. This paper builds an optimization model for ESS of electronic components to obtain the optimal ESS duration. The failure phenomena of ESS are modeled by mixed distribution, and optimal ESS duration is defined by maximizing life-cycle cost savings under the condition of... View full abstract»

    Through research for image compression based on wavelet analysis in recent years, we put forward an adaptive wavelet decomposition strategy. Whether sub-images are to be decomposed or not are decided by their energy defined by certain criterion. Then we derive the adaptive wavelet decomposition tree (AWDT) and the way of adjustable compression ratio. According to the feature of AWDT, this paper al... View full abstract»

    With the development of large-scale complicated modern power systems, the requirement for the associated protection scheme tends to be more stringent and its combination more complex. However, it is very difficult to figure out the factors of failure of such systems. This paper proposes a Petri net model of a transmission line protection relaying system, including three types of relays as well as ... View full abstract»

    In this paper, a new amplitude quantization synthesis method for ultralow sidelobe phased arrays is propose, which is based on the constrained nonlinear optimization algorithm. By introducing a set of critical constraint conditior into the optimization model, we can directly quantize the amplitude distribution instead of replacing it with a continuous equivalent aperture antenna.

    In this paper, we discuss feedback control of a class of delay chaotic maps. Our aim is to drive the chaotic maps to ist initially unstable fixed points by using linear and nonlinear state feedback control. The control is achieved by using small, bounded perturbations. Some numerical simulations are given to demonstrate the effectiveness of the proposed control method. View full abstract»

    In this paper, two improved digital signature schemes are presented based on the design of directed signature scheme [3]. The peculiarity of the system is that only if the scheme is specific recipient, the signature is authenticated. Since the scheme adds the screen of some information parameters, the difficulty of deciphered keys and the security of digital signature system are increased. View full abstract»
