摘要：
This paper presents a novel image encryption scheme based on Arnold mapping and Logistic mapping.It is a digital image encryption algorithm,dual scrambling that based on chaos of pixel position and pixel value. First we separated the three channels of a RGB mode image, then transformed them into 3 two dimensional grey images. respectively scramblinged these gray images of the three colour channels or changed their gray value by different methods,finally combined the three ciphertext into a RGB mode image.The results of experiment simulation show that the key space is large enough to resist the brute-force attack,the ciphertext varies sensitively with any minimal changes of the initial secret key and the plaintext. The algorithm improves the traditional image encryption algorithm of image scrambling based on chaos, and it is valid and has good performance.

摘要：
In order to obtain unification between the robustness and invisibility of watermarking images, under the condition of the same quality of watermark, the more robustness of for anti-interference and noises in image processing can be obtained. Improved watermarking algorithm for color image based on quick block singular value decomposition is proposed. SVD transformation preserves both one-way and non-symmetric properties. This watermarking algorithm is purposed to embed the watermark by both of the U and D components of improved SVD. Experiments and attacks test show that the algorithm has good robustness. Furthermore, the extracted watermark can still be easily identified after tampering.

摘要：
This key technique is to solve the issue of mutual trust establishment between different PKI domains in the future wireless network development for clients. Without Certificate Authority, By adopting threshold scheme, a new roaming hand-off authentication scheme between the different trusted domains in multi-hop wireless network is proposed, then we described and analyzed the process of cross certificate being issued and the steps of roaming hand-off authentication from node leaving former network to joining in new network. and it can provide an efficient method for node's roaming hand-off and secure communication, it has strong flexibility and security, and is comparatively adaptable to the characteristics of wireless network. This technique can be widely used in future progress of wireless network.

摘要：
This paper applies Voronoi diagram into the localization of the wireless sensor network and proposes VBLS (Voronoi diagrams based localization scheme). This algorithm first sorts the received signal strength indicator (RSSI) from the anchor nodes by the order from high to low, computes Voronoi area of each anchor node by using UDG diagram and finally outputs the centroid of the intersection sets of all Voronoi as the localization results. The simulation results of the VBLS are compared with them of the range-free W-Centroid and Centroid. The simulation results indicate that if the anchor nodes are randomly placed, the localization error of VBLS is 18% and 13% lower than it of the Centroid and W-Centroid algorithm respectively;if the anchor nodes are placed uniformly, the localization error of VBLS is 7% lower than it of Centroid algorithm and is 2% higher than it of W-Centroid.

摘要：
A mathematical model for the output waveform of SPWM VSI (voltage source inverter) is created specific to the harmonic problem of SPWM voltage source inverter. Through theoretical analysis and calculation, we can get the distribution regularity of the output harmonic wave in the process of frequency conversion and voltage transformation. Utilizing the matlab to verify the simulation, we can get such results like "frequency conversion will lead to the shift of the harmonic wave's distribution center", "voltage transformation will cause the valuable change of the harmonic wave and the valuable change direction of harmonic wave is opposite to that of the fundamental wave". All of these will have significant guide meaning to the application of SPWM.

摘要：
The paper describe a simulated annealing approach for solving the buffer allocation the problem of optimizing cyclic schedules in polyester staple fiber production lines. The problem entails the determination of the sequence of products in large production lines with the objective of minimizing sum of costs for changeover and holding inventory. The problem concerns the planning and scheduling of a production of two sequence of stages each involving one production line that are interconnected by storage buckets. A mixed-integer programming (MILP) model for cyclic schedules in polyester staple fiber plants is formulated according to traveling salesman problem (TSP). The MILP formulation was applied to a real-world manufacturing facility producing seven final products and solved by a Simulated Annealing algorithm. The computational results are compared to manual in the plant and verified the effectiveness and applicability of the proposed methods.
