At evaluating the combat effectiveness of the defense system, target′s probability to penetrate the defended area is a primary care taking index. In this paper, stochastic model to compete the probability that target penetrates the defended area along any flight path is established by the state analysis and statistical equilibrium analysis of stochastic service system theory. The simulated annealing algorithm is an enlightening random search method based on Monte Carlo recursion, and it can find global optimal solution by simulating annealing process. Combining stochastic model to compete the probability and simulated annealing algorithm, this paper establishes the method to solve problem quantitatively about combat configuration optimization of weapon systems. The calculated result shows that the perfect configuration for fire cells of the weapon is fast found by using this method, and this quantificational method for combat configuration is faster and more scientific than previous one based on principle via map fire field. 展开更多

Distributed Data Mining is expected to discover preciously unknown, implicit and valuable information from massive data set inherently distributed over a network. In recent years several approaches to distributed data mining have been developed, but only a few of them make use of intelligent agents. This paper provides the reason for applying Multi-Agent Technology in Distributed Data Mining and presents a Distributed Data Mining System based on Multi-Agent Technology that deals with heterogeneity in such environment. Based on the advantages of both the CS model and agent-based model, the system is being able to address the specific concern of increasing scalability and enhancing performance. 展开更多

In the mid-latitude regions of the Asian continent, Zhuye Lake is located in the northwest margin of the Asian monsoon, where the modem climate is affected by the Asian monsoon and Westerlies. In this study, we investi- gated the absolutely dated Holocene records in Zhuye Lake for detecting the Holocene climate cycles. Totally, 14 14C dates and 6 optically simulated luminescence (OSL) dates are obtained from the QTH01 and QTH02 sections. The proxies of grain-size, total organic carbon content (TOC), C/N and 813C are used for wavelet analysis, and the results show obvious -256, -512 and -1024-year climate cycles, which are consistent with the Holocene millennial and cen- tennial scale climate cycles in the typical Asian summer monsoon domain. In different parts of the Zhuye Lake, the Holocene sediments show variable climate cycles that are affected by the lake basin topography. In the Zhuye Lake, the Holocene climate cycles are mainly correlated with the solar-related Asian summer monsoon variability and the North Atlantic ice-rafting events. 展开更多

In ubiquitous stub environment, it is a critical challenge to design an optimal device aggregation mechanism to meet all requested ubiquitous services simultaneously with resource- limited devices and bandwidth-limited network. Firstly, Multi-Service oriented Devices Aggregation Problem is generalized and formulated based on QoS-metric with Multi-attribute Decision Making. Secondly, a Multi-Service oriented Devices Aggregation Mechanism is proposed to deal the problem in which there are two processes: Dimensionless Processing and Device Aggregation Approach. At last, the simulation is implemented with OPNET and MATLAB. We integrate different QoS factors, such as Average Utility, Utility distribution, Total Utility distribution and Service Failure Rate, to reflect user experience. 展开更多

Objective: To analyze the main etiological diagnoses of patients attended at a genetics outpatient clinic of the Association of Parents and Friends of Exceptional Children/APAE in the state of Amazonas, Brazil. Methods: retrospective study of patients seen in the period 2005-2016, with review of medical records. The following data were recorded: sex, origin of referral and etiological diagnosis. Results: 362 patients were attended, 94.7% of them from Manaus, and 5.3% from the interior of the state. The etiological diagnosis was defined in 262 (72.3%) of the sample, of which 254 (70.2%) were of genetic etiology and 8 (2.2%) non-genetic. Of the genetic etiologies, 46 (12.7%) cases were monogenic syndromes, 136 (37.6%) were chromosomal aberrations and 72 (19.9%) had multifactorial causes, however, 100 (27.6%) cases remained unclear. There were several syndromes found, with Down syndrome being the most frequent and correlating significantly with the sex of the patient (male predominance, p 〈 0.05). Conclusions: The study carried out in the APAE/Manaus genetics outpatient clinic allowed the profile of the patients being attended to be traced. It was verified that the majority of the patients were male and that the diagnosis of chromosomal alterations was the most frequent. 展开更多

The goal of this paper is to analyze and propose a reconstruction of functional possibilities and database requirements of a Web based Educational Information system. For the research the Information system of the Technology School "electronic Systems" (TUES) associated with the Technical University of Sofia is on focus. The modules for admission of students, specialty classification, and graduation of students, management of the student's work in computer classrooms and lecturers' data management have been analyzed, developed and implemented. The additionally developed modules concern mainly the management of educational process and do not affect the e-learning or the official part modules. That led to the idea that the functionality for managing educational process has to be organized in a separate module defined as module for administrative services of educational process. Such restructuring of the system will bring flexibility in further growth of the system--for example students' admission or selection for different purposes. 展开更多

As one of the most important and strategic actors of sustainable development, the micro-financing (MF) organizations are continuously adopting new strategic methods of collaboration for the success of their micro-financing missions. The paper presents the case of a newly established network of MF organizations created for the strategic objective of not only collaboration but for optimizing inter-organizational knowledge sharing systems for the micro-financing services. The purpose of the paper is to show the method used for the creation of this network, the mechanisms for its management, and the dynamisms and success factor,~ leading to its continuous development. The findings are derived from an interview with one of its most strategic founders, and material is provided by the network, and a questionnaire is administered to the members of the network. The results imply theoretical implications to innovation management and organizational development and change since the source of the creation of this network is innovative, and for the competencies of the founders and their awareness of the importance of change lead to the creation of this network. And the results also lead to managerial implications in the micro-financing sector through the provision of a unique excellent command example to follow. 展开更多

This paper provides an overview of the degradation in CANDU^a (Canadian Deuterium Uranium) feeders in operating plants observed from the mid 1990s onward. The degradation has been dominated by feeder wall thinning, caused by FAC (flow accelerated corrosion) and feeder cracking. This paper summarizes the industry's response to the discovery of these two degradation mechanisms and the methodologies, tools and technologies developed to monitor the degradation and assess the continued fitness for service to manage the plant life. This paper identifies some of the lessons gained from more than a decade of industry effort, and discusses how these lessons are being implemented in the refurbished and new CANDU plants. CANDU^a is a registered trademark of Atomic Energy of Canada Limited. 展开更多
