In this paper, the main research works are as follows : 1 ) survey and analysis previous work in auv navigation and summarize : as the cumulate error, the dead - reckoning and inertial navigation systems ca n ' t be used without other modified system ; the acoustic navigation system is used only in small range, and is very expensive. 2 ) two important approaches in geophysical navigation techniques are summarized, one is terrain contour based navigation, this approach is investigated keystone today ; the other is image based navigation, due to no perfect image sensors and image seabed map, this approach has seldom been practised. 3 ) two important terrain contour based navigation algorithms has been applied to auv, one is match algorithm - based terrain contour match ( tercom ) ; the other is kalman filter - based sandia inertia terrain - aided navigation ( sitan )
主要研究內容包括：一、總結分析了當前水下導航的常用方法和不足之處，指出基於航位推算的導航方法，存在著最大的問題就是導航誤差的積累問題，如果沒有修正系統，這種方法很難滿足使用要求；其次指出基於聲學的導航方法，造價昂貴，導航范圍有限，難以滿足自主水下航行器大范圍導航的需求；二、總結了當前水下地形輔助導航的主要技術路線，一是基於地形高程的匹配方法，這是當前研究的重點；二是基於地形圖像的匹配方法，由於缺乏良好的圖像傳感器，和可用的海底圖像地圖，目前這種方法還有待研究發展；三、將兩種地形高程匹配的常用方法應用到自主水下航行器上：以相關演算法為前提的地形輪廓匹配（ tercom ）方法和以卡爾曼濾波為基礎的桑迪亞慣性地形輔助導航（ sitan ）方法，前者演算法簡單可靠，但是導航精度不高，後者雖然精度比較高，但存在著演算法較為復雜、有可能發散和出現奇異值等問題。 -
Abstract : the theory of variable structure control of sing ular nonlinear control systems was considered based on the singular nonlinear systems itself by employing the method of geography, and gives the sufficient condition of existence of variable structure control and approximation theory of real sliding mode. it is shown that sliding condition only guarantee the slow - varying state of real sliding mode approach that of ideal sliding mode but not guarantee the fast - varying state of real sliding mode approach that of ideal sliding mode. the method applied for studying normal nonlinear system can not be used directely to singular nonlinear system
文摘:利用幾何方法，從廣義非線性系統本身出發，研究了廣義非線性控制系統的變結構控制理論，給出了系統存在變結構控制的充分條件及實際滑動模的近似定理.從所得結論可知，滑動條件僅能保證實際滑動模的慢變狀態趨近於理想滑動模的慢變狀態，而不能保證實際滑動模的快變狀態趨近於理想滑動模的快變狀態，研究正常非線性系統的方法已不能簡單地被利用到廣義非線性系統 -

Generating knowledge ranges from an objective reality, accurately measured and observed phenomena, typically revealed by quantitative techniques ( an analytical approach ) over a systems approach operating with " an objective ( or at least objectively accessible ) reality, consisting of wholes, the outstanding characteristic of which is synergy " ( arbnor and bjerke, 1997 ) to a socially constructed reality based on perceptions, interpretations and actions of different actors

It reframes the traceback problem as a polynomial reconstruction problem, and uses techniques from algebraic coding theory to provide robust methods of transmission and restriction. the scheme is a new solution to the traceback problem during a dos attack ; the honeypot for ddos, which is a tool of traceback, lures the attacker to believe that he successfully compromised a slave for his needs, convincingly simulating the architecture of a potential ddos attack ; the source - based approach to ddos defense, which is a useful adjunt to traceback systems, deploys a ddos defense system at source - end networks. attacks are detected by monitoring two - way traffic flows, and the attacks originating from source networks are stopped by rate - limiting ; the routing mechanism based on pushback treats ddos attacks as a congestion - control problem
