A Planning Heuristic Based On Subgoal Ordering And Helpful Value, Weisheng Li, Peng Tu, Junqing Liu Sep 2012

A Planning Heuristic Based On Subgoal Ordering And Helpful Value, Weisheng Li, Peng Tu, Junqing Liu

Applied Mathematics & Information Sciences

This work is concerned with how to improve the efficiency of heuristic search in a planning system. Utilize the dependency relations between the variables in a goal, a subgoal ordering method is first used to guide the heuristic search in a more reasonable way. The idea of helpful value in a goal is then introduced. A more accurate heuristic cost can be achieved by using the helpful value when we compute the heuristic cost. Finally, a heuristic algorithm combined subgoal ordering with helpful value is proposed. The algorithm is implemented in the planning system Fast Downward. The experimental results show …

System Reliability Allocation Based On Bayesian Network, Wenxue Qian, Xiaowei Yin, Liyang Xie Sep 2012

System Reliability Allocation Based On Bayesian Network, Wenxue Qian, Xiaowei Yin, Liyang Xie

Applied Mathematics & Information Sciences

In this paper, system reliability allocation using BN(Bayesian Network) was researched. The relationship between system failure and component failure can be expressed by probability importance degree, structure importance degree and key importance degree in FTA (Fault Tree Analysis). BN supplies a new method to reflect the importance of components in system. That is the conditional failure probability which points out the most possible reason of system failure and is more reasonable and reliable. Some examples are given to allocate the reliability of systems by BN and the results show that BN is useful and effective.

Nonlinear Distortion Identification Based On Intra-Wave Frequency Modulation, Yutian Wang, Hui Wang, Qin Zhang Sep 2012

Nonlinear Distortion Identification Based On Intra-Wave Frequency Modulation, Yutian Wang, Hui Wang, Qin Zhang

Applied Mathematics & Information Sciences

Recently, most of the methods used to measure and analysis signal property are based on the linear transform theory, such as FFT, STFT, wavelet, etc. Unfortunately, these methods usually cause meaningless results when it is used to analysis nonlinear signal. In this paper, we use Hilbert-Huang transform (HHT) to review the nonlinear distortion and define a novel nonlinear parameter named Nonlinear Distortion Degree (NDD) which is based on intra-wave frequency modulation measurement. The loudspeaker model simulations are used to illustrate the intra-wave frequency modulation caused by nonlinear distortion. The results agree that NDD can reveal more accurate and physical meaningful …

A new method for defining the fuzzy closeness degree is put forward in this paper. Based on the closeness degree, another generalization of belief and plausibility functions to fuzzy sets is proposed which discards the max and min operators in foregoing generalizations according to the measure of fuzzy inclusion. We then make the comparisons of the proposed extension with some methods available. The …

Detecting Hidden Anomalies Using Sketch For High-Speed Network Data Stream Monitoring, Aiping Li, Yi Han, Bin Zhou, Weihong Han, Yan Jia

Applied Mathematics & Information Sciences

Monitoring network data streams in real-time to check security event become more and more important along with the rapid growth of Internet applications. The detection typically treats the traffic as a collection of flows that need to be examined for significant changes in traffic pattern (e.g., volume, number of connections). However, as link speeds and the number of flows increase, keeping perflow state is either too expensive or too slow.We propose building compact summaries of the traffic data using the notion of sketches.In this paper, we proposed an IP address traceability network anomaly detection method at right time based on …

A Genetic Algorithm Approach For Toc-Based Supply Chain Coordination, Kaijun Leng, Xiangjun Chen Sep 2012

A Genetic Algorithm Approach For Toc-Based Supply Chain Coordination, Kaijun Leng, Xiangjun Chen

Applied Mathematics & Information Sciences

A supply chain is a network of retailers, distributors, manufacturers, and suppliers cooperating to satisfy customers demands. In traditional business environments, each business tries to minimize its costs based on its own cost structure, regardless of other SC participants. However, most decisions made by each SC members are based on the profitability of their own. In this paper, we consider a two-level supply chain in which retailer orders exceeds the suppliers capacity. To balance supply and demand, we proposed a coordination mechanism based on Theory of Constraints (TOC) in face of meeting peak demand in certain period for the whole …

Teleportation In The Presence Of Technical Defects In Transmission Stations, A.-H. M. Ahmed, M. N. Zakaria, N. Metwally

Applied Mathematics & Information Sciences

The process of teleport information remotely in presence of an error in the implementation of the local operations as CNOT and Hadamard gate at the sending station is discussed. Through the control of the laboratory equipment the errors in the achieving the local operations could be resisted. The imperfect CNOT gates performance could be improved as the error’s strength in implementing of the Hadamard gate increases. It is shown that the accuracy of the information transfer not only depends on the laboratory equipment, but also on nature of the information to be teleported.

Receding Horizon Chaos Synchronization Method, Choon Ki Ahn, Chul Dong Lee, Moon Kyou Song Sep 2012

Receding Horizon Chaos Synchronization Method, Choon Ki Ahn, Chul Dong Lee, Moon Kyou Song

Applied Mathematics & Information Sciences

This article proposes a new synchronization method, called a receding horizon synchronization (RHS) method, for a general class of chaotic systems. A new linear matrix inequality (LMI) condition on the finite terminal weighting matrix is proposed for chaotic systems under which non-increasing monotonicity of the optimal cost is guaranteed. It is shown that the proposed terminal inequality condition guarantees the closed-loop stability of the RHS method for chaotic systems. As an application of the proposed method, the RHS problem for Chua’s chaotic system is investigated.

Sana Crítica: The System For Weighing Evidence Utilized By The Inter-American Court Of Human Rights, Álvaro Paúl

Buffalo Human Rights Law Review

The Spanish version of the case law of the Inter-American Court of Human Rights often states that this tribunal's as- sessment of evidence is ruled by saia crilica, a notion which has received several translations in the English ver- sion of the Court's case law. This concept has a clear mean- ing in the Hispanic civil law tradition. Sana critica is a system for evaluating the weight of evidence whereby a court or tribunal is not constrained by the evidentiary rules of legal proo but must judge in accordance with the rules of logic and experience, and state the grounds …
