FLOOD EXTENT MAPPING USING DUAL-POLARIMETRIC SENTINEL-1 SYNTHETIC APERTURE RADAR IMAGERY
Flood Polarimetry SAR Radar Harvey Sentinel-1
2018/4/30
Rapid generation of synthetic aperture radar (SAR) based flood extent maps provide valuable data in disaster response efforts thanks to the cloud penetrating ability of microwaves. We present a method...
USE OF MULTIVARIATE MACHINE LEARNING ANALYSIS TECHNIQUES FOR FLOOD RISK PREVENTION
flood risk data Machine Learning Prediction
2018/3/6
Natural disasters such as flood are regarded to be caused by extreme weather conditions as well as changes in global and regional climate.
The prediction of flood incoming is a key factor to ensure c...

LIDAR FILTERING ALGORITHMS FOR URBAN FLOOD APPLICATION: REVIEW ON CURRENT ALGORITHMS AND FILTERS TEST
LiDAR Filtering Algorithm Digital terrain model (DTM) Urban flood modelling Classification Urban Flood
2016/2/29
Digital terrain model (DTM) is one of the important input parameters in urban flood application. This is because it influences the
flow direction, flow velocity, flood extend and flood depth. LiDAR ...
UNCERTAINTY IN CALIBRATING FLOOD PROPAGATION MODELS WITH FLOOD BOUNDARIES DERIVED FROM SYNTHETIC APERTURE RADAR IMAGERY
Remote Sensing Floods Classification Calibration SAR Performance Fuzzy Logic

An instantaneous synthetic aperture radar (SAR) derived flood extent map helps retrieving the distributed conveyance parameters in
one-dimensional flood routing models. These models are generally ca...
针对现有网络安全设施无法有效防御非对称路由环境下流量规模较大的SYN flood攻击的问题，对SYN flood攻击检测技术和TCP连接管理策略进行研究，提出了一种轻量级攻击检测和混合连接管理策略相结合的防御方法，利用SYN分组比例和目的地址熵进行攻击检测，并根据检测结果对基于SYN的连接管理策略和基于数据的连接管理策略进行灵活切换。实验证明该防御方法能有效地减轻SYN flood攻击对网络安全设...
An Approach for Estimating the Design Flood Flowline on Developed Rivers
River hydraulics Developed rivers Flood-stage relation Maximum flood Design discharge
2009/10/12
The stages produced by the major floods on developed rivers (like the Rhine in Europe, the Mississippi and the Red rivers in the USA) indicate that existing stage-discharge relationships are usually s...
在对图像特征进行有效分割的基础上,提出了一种基于红外成像障碍物检测的改进Flood Filling 算法,并首次将该 算法应用到障碍物检测领域中。通过对模拟以及真实红外图像中目标的快速成功提取,不仅验证了该方法的有效性,同时实 验结果也表明了其较之原始算法对时效性的提高。
