双浮体波浪能转换装置中重心布置对波浪能吸收影响分析

提出一种基于横摇运动的双浮体波浪能转换装置,利用水面浮体与水下浮体之间的相对横摇运动实现对波浪能的吸收。在保持水下浮体稳定的前提下,水面浮体的横摇运动决定了整个装置对波浪能吸收情况。水面浮体的横摇运动受其横摇固有频率的影响,主要是重心布置。为了合理选择水面浮体的重心位置,采用数值分析的方法对箱型浮体在长峰不规则波下的工作情况进行分析,讨论重心布置对波浪能吸收的影响以及对PTO参数选择的影响。结果表明,重心的布置可改变波浪能吸收的频段,重心布置越低,可吸收的波浪能频段越广,越有利于波浪能的吸收。

Waypoint analysis for command and control

Command and Control (C2) in a military setting can be epitomized in battles‐of‐old when commanders would seek high ground to gain superior spatial‐temporal information; from this vantage point, decisions were made and relayed to units in the field. Although the fundamentals remain, technology has changed the practice of C2; for example, enemy units may be observed remotely, with instruments of varying positional accuracy. A basic problem in C2 is the ability to track an enemy object in the battlespace and to forecast its future position; the (extended) Kalman filter provides a straightforward solution. The problem changes fundamentally if one assumes that the moving object is headed for an (unknown) location, or waypoint. This article is concerned with the new problem of estimation of such a waypoint, for which we use Bayesian statistical prediction. The computational burden is greater than an ad hoc regression‐based estimate, which we also develop, but the Bayesian approach has a big advantage in that it yields both a predictor and a measure of its variability. © 2004 Wiley Periodicals, Inc.

猎击时敏目标的作战机理分析

美军在第二次对伊战争中,以比第一次对伊战争少得多的兵力,更短的准备时间和更少的消耗取得了更大的胜利,对比两次对伊战争中所用的兵器,坦克、主战飞机、战车、轻兵器等主战装备基本还是上次对伊战争的旧兵器,最大的变化是无人机的大量使用,情报系统、战术网络的提升,使战斗能力有极大的提高,这种由系统整合、提升信息化能力、改进指挥控制所产生的作战效能的提升是显著和有效的,代表发展战争潜力的方向。文中以美军对伊战争中主要的作战样式——打击时敏目标为作战想定,建立作战系统猎击时敏目标作战效能模型,对影响作战系统效能的各种因素作定量的分析,揭示作战效能提升的机理。     

Automated integration of real-time and non-real-time defense systems

Various application domains require the integration of distributed real-time or near-real-time systems with non-real-time systems.Smart cities,smart homes,ambient intelligent systems,or network-centric defense systems are among these application domains.Data Distribution Service(DDS)is a communi-cation mechanism based on Data-Centric Publish-Subscribe(DCPS)model.It is used for distributed systems with real-time operational constraints.Java Message Service(JMS)is a messaging standard for enterprise systems using Service Oriented Architecture(SOA)for non-real-time operations.JMS allows Java programs to exchange messages in a loosely coupled fashion.JMS also supports sending and receiving messages using a messaging queue and a publish-subscribe interface.In this article,we pro-pose an architecture enabling the automated integration of distributed real-time and non-real-time systems.We test our proposed architecture using a distributed Command,Control,Communications,Computers,and Intelligence(C4I)system.The system has DDS-based real-time Combat Management System components deployed to naval warships,and SOA-based non-real-time Command and Control components used at headquarters.The proposed solution enables the exchange of data between these two systems efficiently.We compare the proposed solution with a similar study.Our solution is superior in terms of automation support,ease of implementation,scalability,and performance.
