High reliability is usually the most important requirement in space applications. There is no hardware repair for them. Long mission times and harsh environment are a challenge for electronic circuits, and particular error mitigation techniques have to be implemented in order to be able to cope with the expected error effects. Always, Triple Modular Redundancy (TMR) is relied mostly to prevent SEUs from causing functional errors. And in recent decades, SRAM-based FPGAs are used a lot in space for its high performance and flexibility. However, use of FPGAs in space applications can also be challenging. They are too susceptible to transient faults, such as SEUs. Reconfiguration provides more possibilities for SRAM-based FPGAs into space. Reconfigurable technology solves the disadvantage that the TMR modules cannot heal the error themselves. Additionally, reconfiguration is an improvement in terms of resource utilization and costs. In this paper, TMR and reconfigurable computing are combined to level up the reliability of the space applications. The paper proposed a reconfigurable computing architecture based on a TMR system. A new kind of reconfigurable architecture using SoP (system-on-a-package) technology is presented. Also, a whole space application will be presented.

Recording and replaying of situation data is critical in the battle simulation system, which is the foundation of the subsequent analysis and evaluation. First of all, the demand for recording and replaying of situation data in the simulation system was expatiated, and then the realizing methods, that is, integrated federation member and embedded programs were analyzed. The situation data object was defined according to the requirements of serialization, and the process of data recording and replaying was analyzed in detail. Moreover, the Zlib function library which supports memory compression and uncompression was referred to specifically.

Arbitrary Lagrangian-Eulerian (ALE) Finite Element Method is used to solve the fluid-structure interaction problem in the explosion shock. The fluid and explosive models are described by ALE algorithm, the structure model of rudder is represented in Lagrangain method. And also penalty function coupling algorithm is applied to the interface between different medium. The simulation of the whole process of ship rudder suffering from the shock of TNT explosion is accomplished by finite element software ANSYS/LS-DYNA. The shock response, including stress and displacement nephogram of rudder, pressure-time process curve in the typical position, and acceleration-time curve etc. is presented. The results show that using ALE finite element method can estimate the damage situation of rudder in underwater explosion impact load, which provide references for the anti-shock design of rudder.

Finding gradient maximum and local maximum based on multi-scale Canny operator edge detection is really the optimization for two dimension multi-element function. The maximal function gradient or local maximum which was derived by the traditional analytics is approximate and local. A new multi-scale edge detection algorithm is proposed by a genetic optimum searching algorithm. To upgrade the genetic algorithm convergence about edge detection, an improved GA+SA+TABU is used in order to overcome the defects of local searching in the general genetic algorithm and upgrade the whole resolution. Alternating optimization tactics are utilized by combining the general algorithm and heuristic searching methods. The experimental results show that the proposed algorithm applied to IR target image segmentation could result in copious details, single edge and exact location.

Star sensors and gyros are widely used in satellite attitude determination system. Datum error, induced by using these sensors, has great influence on the accuracy of attitude determination. To analyze this influence, we first construct sensors' measurement model with datum error in this paper. Then, the influences caused by star sensors' and gyros' datum errors are analyzed by employing minimum variance estimation principle. Finally, the permissible datum errors' ranges are determined by simulation. Experimental results show that star sensors' datum error has significant influence on attitude determination accuracy. Influence of gyros' datum error, however, has relatively smaller effect, especially when the datum error of gyros' is within the predetermined range.

The safety assessment of thermal control system is an essential component of safety evaluation of the whole thermal power plant. The index system for safety assessment was constructed, and methods of deciding initial weights for each factor of the index system were presented. In order to strengthen the influence resulted from small faults factors on the overall safety evaluation a variable weight method was proposed. A method of fuzzy pattern recognition was employed to assess the safety of thermal control system. The analyses of instances show that the assessment method is feasible and effective.

To overcome the shortcomings of wired natural gas intelligent alarming system, a natural gas intelligent alarming system based on wireless sensor networks was designed. The components of the system and its working principle were described in detail. Its nodes use a density sensor for data collection, wireless transmission chip CC1101 for data short-range wireless transceiver and the wireless network, and MSP430F449 microcontroller for controlling core. Nodes communicate with the background host through serial interfaces. The system can achieve density of natural gas dynamically and comprehensive real-time monitoring. Node has a dual function as terminals and routers, in addition to data processing, but also for other nodes to forward the density data storage, management, and integration, and taking in collaboration with other nodes to complete some specific tasks. The system has some advantages such as low cost, low power consumption and small size, which has a good application prospects.
