Since these theoretical analyses are based on inviscid potential flow theory, theoretical calculation and computational simulation may complement each other. the hydrodynamics and undulating propulsion of specimens were studied using three dimensional computational fluid dynamics ( cfd ) modeling. the cfd analysis using kinematic model of undulatory dorsal / median fin draws a series of conclusions, which include that the body drag increases significantly with the lateral body oscillation ; the body drag is minimum while the start point of
計算結果表明游動過程中的形體阻力隨側向周期性擺動而增大;當背鰭前端位於身體側向最寬處時,形體阻力具有局部最小值,結論與實驗觀測結果相吻合;在實驗觀測的典型運動參數下,波動面的運動方程中的非對稱因素的出現使推進力增大約1 . 10倍。The ids works by two way, misuse detection and anomaly detection, misuse detection flags an intrusion on intrusion signature, this kind of detecting technic can be realized much more easily, and much more accurate, but it can not find some intrusiones that have been disguised or new kinds of intrusion. the anomaly detection can detect in more wide field, anomaly detection can compare new statistic data with average record, then anomaly record will be found, but it ' s more difficult to set a threshold, if the threshold is too big, some intrusion may be put through, if the threshold is too small, the ids will give more false positive alarm, and the threshold will be different with different people or different period, so the ids just simply show us their suspicious record, the administrator or expert will be in duty to analyze this record and give conclusion, the ids give more alarm than it should, leave us more detection record to analyze, and this is a hard work, we can not distinguish an intrusion or not if we analyze only one record, but we can judge if we find the relation among mass detection evidence. in this article, we try distinguish an intrusion using d - s theory ( proof theory ) instead using manual work, the ids will be more helpful and efficient
濫用檢測採用的是特徵檢測的方法,實現較為簡單,判斷的準確性較高,但是不能判斷一些經過偽裝的入侵或特徵庫中尚未包含的入侵,異常檢測能夠根據以往記錄的特徵平均值,判斷出異常情況,但是對于異常到什麼程度才視為入侵,這個閥值非常難以確定,閥值設定的太高,有可能漏過真正的入侵,如果設定的閥值太低,又會產生較高的誤警率,而且這個閥值因人而異,因時而異,因此現在的入侵檢測系統把這部分異常記錄以一定的形式顯示出來或通知管理人員,交給管理人員去判斷,而這些ids系統難以判斷的記錄,如果對每個證據單獨地進行觀察,可能是難以判斷是否是入侵,而把許多先後證據關聯起來,專家或管理人員根據經驗能夠判斷訪問的合法性,本文試圖引入人工智慧中證據理論的推理策略和示例學習方法,代替人工檢查分析,可以提高效率,降低誤警率,並可以對一個正在進行得可疑訪問實現實時檢測,通過搜索及時判斷,及時阻斷非法訪問,比事後得人工處理更有意義。In order to take microstructures into account, the tested values of the corresponding physical properties of w - alloy, mo - alloy and ti - alloy are used as basic data during estimation. and the estimated values match those tested ones very well. several typical micromechanical models for elastic properties are introduced and compared in this paper
以鎢合金、鉬合金和鈦合金相應物性參數的實驗值為基礎進行預測,可以間接考慮到微觀結構的影響因素,這樣得到的預測結果與實驗值符合地非常好,預測結果具有較高的可信度。Those prove those two method have good estimator in those situations. last bring forward some problems need improve. we can draw the follow conclusions from simulation and theoretic analysis : nonlinear observer and ins / gps system have those virtues : high estimated precision good - robustness and simple structure, convenience used to engineer, it can replace the measured value of sensors or be used to detect fault
通過理論分析和模擬驗證,我們得到如下的結論:非線性觀測器方法具有估冠穿北口二習七大學碩創七學位論文計精度高、很好抗干擾能力; ins / gps系統方法具有結構簡單,易於工程實現,實時性好;兩種方法均具有很高的工程應用價值,能夠為現有硬體傳感器提供一個解析余度信號和提高傳感器的可靠性水平。分享友人
