Land use/cover change effects on floods with different return periods: a case study of Beijing, China

Yueling WANG, Xiaoliu YANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5,   Pages 769-776 doi: 10.1007/s11783-013-0542-z

Abstract: statistical methods was applied to quantify the effect of LUCC on floods in terms of inundation extent, floodarrival time and maximum water depth.period of analysis Beijing experienced unprecedented LUCC; 2) LUCC can affect inundation extent and floodarrival time, and floods with longer return periods are more influenced; 3) LUCC can affect maximumwater depth and floods with shorter return periods are more influenced; and 4) LUCC is a major flood

Acoustic localization with multi-layer isogradient sound speed profile using TDOA and FDOA Research Article

Dongzhou ZHAN, Sitian WANG, Shougui CAI, Huarong ZHENG, Wen XU,wxu@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 1,   Pages 164-175 doi: 10.1631/FITEE.2100398

Abstract: In the underwater medium, the speed of sound varies with water depth, temperature, and salinity. The inhomogeneity of water leads to bending of sound rays, making the existing localization algorithms based on straight-line propagation less precise. To realize high-precision node positioning in s (UASNs), a multi-layer isogradient (SSP) model is developed using the linear segmentation approximation approach. Then, the sound ray tracking problem is converted into a polynomial root-searching problem. Based on the derived gradient of the signal's Doppler shift at the sensor node, a novel underwater node localization algorithm is proposed using both the and . Simulations are implemented to illustrate the effectiveness of the proposed algorithm. Compared with the traditional straight-line propagation method, the proposed algorithm can effectively handle the sound ray bending phenomenon. Estimation accuracy with different SSP modeling errors is also investigated. Overall, accurate and reliable node localization can be achieved.
