无人机集群反制技术剖析

无人机集群作战具有作战效能高、战场生存能力强、效费比极高的巨大优势,将给传统防空系统带来巨大挑战.现有反无人机集群技术大多来源于反无人机技术,但反平台与反集群存在显著差异,必须针对无人机集群自身技战术特点,加强对精确/高效/低成本的集群反制技术研究.因此,本文以剖析无人机集群反制技术的可行性为出发点,首先,从反无人机集...     

教育阻断深度贫困地区贫困代际传递的作用分析——基于新疆八个地区的实证研究

教育既是阻断贫困代际传递的治本之策,亦是脱贫可持续发展的内生动力。本研究基于新疆八个地区的实地调研数据,运用转换矩阵分析法和对数线性回归模型呈现了贫困代际传递与教育代际流动的现状,进而分析各级教育阻断贫困代际传递的作用,结果表明,贫困结构由绝对贫困向相对贫困改善;贫困子代受教育程度低,教育向上代际流动性较弱;教育具有阻断贫困代际传递的作用,中学教育阶段最为显著。教育扶贫应精准识别扶贫对象,增强受教育意愿,促进教育代际流动;差异分配教育经费,分学段扶贫;培养与引进并举,加强师资建设。     

A misclassification cost‐minimizing evolutionary–neural classification approach

Machine learning algorithms that incorporate misclassification costs have recently received considerable attention. In this paper, we use the principles of evolution to develop and test an evolutionary/genetic algorithm (GA)‐based neural approach that incorporates asymmetric Type I and Type II error costs. Using simulated, real‐world medical and financial data sets, we compare the results of the proposed approach with other statistical, mathematical, and machine learning approaches, which include statistical linear discriminant analysis, back‐propagation artificial neural network, integrated cost preference‐based linear mathematical programming‐based minimize squared deviations, linear integrated cost preference‐based GA, decision trees (C 5.0, and CART), and inexpensive classification with expensive tests algorithm. Our results indicate that the proposed approach incorporating asymmetric error costs results in equal or lower holdout sample misclassification cost when compared with the other statistical, mathematical, and machine learning misclassification cost‐minimizing approaches. © 2006 Wiley Periodicals, Inc.

Nuclear security culture enhancement: the role of culture coordinators at Russian nuclear sites

In 2002, a Nuclear Security Culture (NSC) Enhancement Program with the mission to raise the level of the NSC at sites and facilities in Russia's nuclear complex was launched under the guidance of the Russian State Corporation “ROSATOM” and with support from the US Department of Energy. A Joint Working Group for NSC with both Russian Federation and US members was formed and charged with the design and implementation of the program. The program was implemented at sites and facilities on a pilot basis. Nine sites participated in the Pilot Project. The key program component was an establishment of Culture Coordinators (CCs) with the authority to coordinate and implement NSC enhancement activities at sites and facilities. The CCs have served as the force that has maintained the momentum of the Pilot Project and continuously steered the site NSC enhancement efforts. The contribution of the CCs in achieving the positive outcomes of the program cannot be overstated.
