The Picard-HSS-SOR iteration method for absolute value equations

Abstract: In this paper, we present the Picard-HSS-SOR iteration method for finding the solution of the absolute value equation (AVE), which is more efficient than the Picard-HSS iteration method for AVE. The convergence results of the Picard-HSS-SOR iteration method are proved under certain assumptions imposed on the involved parameter. Numerical experiments demonstrate that the Picard-HSS-SOR iteration method for solving absolute value equations is feasible and effective.

Research on Self-Adaptive Group Key Management in Deep Space Networks

Abstract: Deep space network is a must-have technology to improve communication, navigation, and propulsion in future space missions, a very long physical distance among space entities is difficult to overcome efficiently as a space mission could cover a huge space, some distinguished negative features including long time delay and non-reliable end-to-end link deteriorate channel state seriously, thence the operations of rekey could not be implemented on time due to poor channel state which incurs frequently failure and provides more opportunities for adversary in assaulting group key management consequently. To solve the question, a self-adaption group key management scheme is put forward for long time delay and non-reliable end-to-end link network, multi-decryption keys protocol is designed as a container for involving shared decryption keys, every shared decryption key is divided into a few key fragments with threshold cryptograph whose scale is different to adjust the environment requirement, so different numbers of key fragments are applied to the decryption process according to the channel state, the public key material can be revised by a legitimated entity for rekeying without 1-affect-n problem. Any legitimated entities have capability of cooperating to implement different decryption process with different threshold cryptograph mechanisms, thus a few entities cooperate to withdraw a shared key without the leaving entity’s participation in rekeying, so the reliable end-to-end channel for the leaving entity is not necessary. In security aspect, the decryption keys meet key independence, the backward security and forward security are guaranteed in rekeying, and the probability of selected cipher text attack is negligible for an adversary under hardness assumption. Therefore the suggested scheme provides a less message cost rekeying method, it reduces time delay, and the failure of rekeying is tolerated in order to adapt to the non-reliable end-to-end link. Therefore the suggested scheme is suitable to long time delay and non-reliable end-to-end link deep space networks.

Empirical Research on Relations of China's Energy Consumption to Its Industrial Development

Abstract: As an important foundation for resources, energy, being an important strategic commodity for the survival of human, economic development and social progress, has been related to national economic lifelines and national security, which plays a decisive role in the modernization of China. Through correlation analysis between China's energy consumption by the industrial and its total energy consumption, the impact of China's current industrial structure on energy consumption can be drawn, while the interactive process of China's energy consumption associated with the main industrial energy consumption will be further understood with the devices of Granger causality test and VAR impulse response. The Government should implement means of incentive and restraint to encourage and guide manufacturers to participate in the construction of a new type of industrialization on their own initiative. This is the only way to realize China's sustained and effective energy-saving policy, and to promote its ecological modernization process finally.

Bifurcation Analysis of a Delayed Worm Propagation Model with Saturated Incidence

Abstract: This paper is concerned with a delayed SVEIR worm propagation model with saturated incidence. The main objective is to investigate the effect of the time delay on the model. Sufficient conditions for local stability of the positive equilibrium and existence of a Hopf bifurcation are obtained by choosing the time delay as the bifurcation parameter. Particularly, explicit formulas determining direction of the Hopf bifurcation and stability of the bifurcating periodic solutions are derived by using the normal form theory and the center manifold theorem. Numerical simulations for a set of parameter values are carried out to illustrate the analytical results.
