It has proved that non-convex optimization with the feasible set satisfying quasi-normal cone condition (QNCC) can be solved by the method of Homotopy Interior Point (HIP) Method with global convergence under the hypothesis that a quasi-normal cone has been constructed. But how to construct the quasi-normal cone for a general non-convex set is very difficult and there is no uniform and efficient method to do it. In this paper, we give a method to construct a quasi-normal cone for a class of sets satisfying QNCC, and construct HIP function and realize the HIP method algorithms. And we prove it is available by the numerical example at the same time.

Buffer overflow attack is the most common and arguably the most dangerous attack method. The buffer overflow detecting will play a significant role in network security filed. Various solutions have been developed to address the buffer overflow vulnerability problem. The paper presents a method that combines static analysis with dynamic test. By using the method we can identify a lot of potential weakness locations. A buffer overflow vulnerabilities testing system was developed. Using the system some PE-format files and dynamic link library files are detected respectively. The experiment results show that the method is feasibility and availability.

Second order system is often applied in engineering and many high order systems can be simplified to second order systems. All the systems can be described by tipycal second order differential equation. It is the homogeneous solution of second order differential equation that is most critical in the long-term behavior of the system. For that, a new method of decoupling multi-degree-of-freedom system is proposed by similarity transformation this paper. on the premise of preserving the characteristics for second order system, the question of diagonalizing three system matrices simultaneous can be converted to the question of diagonalizing two system matrices under the same condition by similarity transformation. From the result of numerical experiment, we find that the decoupling method of second order system proposed in this paper is efficient.

An approaches to determination the center point of lines's width direction and edges of ellipses, from 2D images are proposed. For the center point of line's width direction, geometric models for line profiles are used to analyze their feature. From this analysis, algorithms to extract center point of line's width direction with sub pixel resolution are derived. To extract edges of ellipses, they are regarded as the center of lines in the gradient image of 2D images. Through the least-squares ellipse fitting, the center of ellipse is determinated. Finally give a conclusion about the center of gravity of the region, the method in this paper and canny filter.

As an important unit composing Wireless Sensor Networks, sensor node normally integrates sensor, data processing unit and communicating module. Power consuming and data transmitting rate are the key factors affecting the quality of it. Regarding the characteristics mentioned, we designed a new wireless sensor network node based on nRF2401. Since the node using low power consumption processor ATmega88 and wireless communication module nRF2401, it guarantees the system operating life and data transmission speed efficiently. Furthermore, the digital thermometer DS18B20 based on 1-wire technology can give the system more concision and more reliability. This node easily applies to Wireless Sensor Networks widely, with its characteristics of low-power, miniaturization and high integration.

Transmission system is the core part of a train. It plays a key role in train's safe and reliable running to real-time monitor its key parameters.[1][2] The real-time monitor software of traction and drive system's key parameters based on VC++ and Intouch software is designed and completed according to the requirements of the parameters. After briefly introducing the basic working principle of DDE protocol, I analyze the hardware design structure of the real-time monitoring system and put forward the design methods of monitoring software, realizing the back-end data acquisition function and front-end data display function which both developed in both VC++ and Intouch environment as well as the data exchange and coordination function between the two platforms that completed via DDE protocol. The software has been put into use to monitor the running conditions of transmission system of rails for a long time since its completion, thereby offers scientific technical offers to locomotive manufacturers. That is, the system has reached desired effects and high using value.

A new time-varying parameter-based model for target tracking in two dimensions is developed. The target maneuvers are modeled by incorporating tangential- and normal-tack acceleration inputs, the former is characterized by a time-correlated stochastic process and the latter is parameterized by heading-rate, therefore unlike the usual evolution equation with fixed-structure, the proposed model describes complex maneuvering a parameterized formula. By adopting a modified Rao-Blackwellised scheme to evolve the unknown parameter - heading online, the approach implements a tracking by using a varying-structure model. Revealing by a number of Monte-Carlo simulations, the proposed tracker exhibits considerably well computational accuracy compared with a standard interacting multiple model(IMM) estimator, meanwhile the time consumption is more less than that of IMM.
