The separation of radionuclides is critical for the sustainable development of nuclear energy. It is urgent to design and prepare functionalized materials for efficient radionuclides separation. Porous materials are considered excellent candidates for the separation of radionuclides under complex conditions due to their high specific surface areas, tunable pore structures and controllable functionalities. In this review, we summarized the design, preparation and functionalization of porous materials and their application for separation of radionuclides in the past five years, discussed the separation performance and analyzed the structure-activity relationship between various radionuclides and porous materials, and systematically clarified their characterization and mechanism of different type porous materials. We also introduced the detection, irradiation and chemical toxicity of different reflective radionuclides.

Service-oriented advanced avionics system could implement system integration and information sharing by servicizing resources with multi-participant. In this system, each participant is bounded rational and may take aberrant behaviors. Different participant behaviors will cause the system to evolve towards different directions. In this paper, the evolution of service-oriented advanced avionics system is studied from the perspective of service management. A tripartite asymmetric game model is established to describe the participant behaviors. The replicated dynamic equation is applied to analyze the system stability. The sufficient condition of system stability is given. The research work contributes to predicting and controlling the evolution of this system accurately. The simulation results indicate that the game model and analysis method are correct and practical.

Integrated Modular avionics (IMA) is the latest generation of avionics systems, with a high level of integration and modularity that make more integrated functions and more sharing of resources. Software product line engineering (SPLE) approaches can reduce the cost associated with developing complex systems like IMA and obtain More IMA configurations which meet user requirements. Feature selection of the feature model resulting from the domain modeling is a key step in obtaining the functionality needed and the characteristics of the user. Due to the high safety requirements of the IMA system, various resident applications need to be provisioned at development time to meet various safety constraints, which makes the feature selection process need to consider the IMA resource configuration constraints. In this paper, by extending the feature model, the feature model can express the information of the software mapping in the IMA resource configuration. We also used the multi-objective genetic algorithm to optimize the functional and non-functional requirements. Moreover, experiments are carried out on different scale models to verify the effectiveness of the method.

Many systems are required to perform maintenance actions at the breaks between successive missions. However, it is often impossible to perform all the desirable maintenance actions due to the limited time of the breaks. In such a case, many selective maintenance models were proposed for this problem. In this paper, we propose a selective maintenance model considering the different mission duration time for different subsystems. We formulate the selective maintenance model as a non-linear 0-1 programming problem. The maximum reliability of the next mission is formulated as objective. The effectiveness of the proposed model is demonstrated via a numerical example.

Line segments are ordinary in industrial scene, accurate line segments matching is a key step for many applications, such as 3-D reconstruction. A matching method based on epipolar-line constraint and line segment features is proposed. Firstly, the points on line segments between image pairs are matched by epipolar-line constraint. Secondly, geometric descriptor and gray value descriptor are used to describe the line segment features, then the two descriptors are combined into a feature vector, and Euclidean distance between vectors is used to achieve fine match. Experiment results show that the proposed method is accurate and fast. © 2011 ACADEMY PUBLISHER.

Integrated modular avionics systems bring new concepts and benefits for function integration and resource utilization in developing advanced aircraft avionics, as well as a series of challenges related to hazard analysis in components interaction and functions operation. When software applications provided independently by the subsystem developers are integrated onto the IMA hardware platform, it is very difficult for designers to understand and predict how the system will behave and what interaction hazards could occur. Although the ARP 4761-based safety analysis methods have solved a large number of safety problems on the development of civil aircraft and system designs in early times, there are some limitations when analyzing more and more complex integrated modular avionics systems in modern times. To gain a good or better understanding and a comprehensive awareness of applications interaction hazards in today’s more complex, software-intensive IMA systems, it is significant to use a method to consider these new causal factors that are not handled by the older techniques and to provide more guidance to the analyst in performing hazard analysis. system-Theoretic Process Analysis (STPA) is one of typical systemic hazard analysis methods. STPA has its foundation in a new accident causality model called STAMP (system-Theoretic Accident Model and Process). STAMP was proposed based on the cybernetics of systems theory. In STAMP, the dysfunctional interactions and requirements flaws during operation are primary types of inadequate control. The STPA-based hazard analysis method is extended in this paper to account for behavior that emerges when software applications are integrated and make functional interaction. This method will be capable of modeling the new causal factors that contribute to component interaction hazards. The paper illustrates the new method with a case that includes real-world avionics display functions, this application of the proposed method will b
