The orbital angular momentum (OAM) wave has shown great potential for improving radar imaging and underwater communication performance due to its helical wavefront phase infinite orthogonal modes. However, there are currently no known applications of this technology in imaging. In paper, we employed acoustic OAM established transceiver signal models using the uniform circular array. We concurrently achieved two-dimensional azimuth elevation angles, which differs from proposed a matching...
Orthogonal frequency division multiplexing (OFDM) is a prevalent scheme for medium-range high-speed underwater acoustic communication; therefore, carrier offset (CFO) estimation and compensation have been widely researched to maintain the orthogonality among subcarriers. However, CFO assumed be constant, or it changes only OFDM blocks convenience. Few studies focused on intrablock CFO, which practical case. In this study, slowly time-varying channel sequential proposed based relationship...
In order to extract quantitative water‐leaving information from the Thematic Mapper (TM) image accurately in inland waters, atmospheric correction is a necessary step. Based on former researchers' results, paper presents two algorithms based meteorological data (MD) and Moderate Resolution Imaging Spectroradiometer (MODIS) Vicarious Calibration (MVC) for TM waters according theory of radiative transfer. Studying Taihu lake, China, this we derived water remote sensing reflectance 26 July 2004...
Increasing concentrations of dissolved organic carbon (DOC) have been observed in coastal ecosystems worldwide over the past decade, and tight coupling (C) phosphorus (P) biogeochemical cycle has recognized aquatic ecosystems. However, there is still no consensus regarding potential effects DOC loading on sediment P release. In a 2-month mesocosm experiment, we tested enrichment release six glass aquariums. Two treatments were set: Control (without sodium acetate (Na(CH 3 COO)) addition)...
OBJECTIVE CT and MRI are synergistic in the information provided for neurosurgical planning. While obtaining both types of images lends unique data from each, doing so adds to cost exposes patients additional ionizing radiation after has been performed. Cross-modal synthesis high-resolution sequences offers an appealing solution. The authors therefore sought develop a deep learning conditional generative adversarial network (cGAN) which performs this synthesis. METHODS Preoperative paired...
ABSTRACT Clustering analysis of small watersheds is an effective tool for identifying the similarity runoff generation and concentration. In this paper, 545 in hilly areas Shandong Province were investigated, 12 indicators representing their climate subsurface characteristics selected to identify communities based on hydrological similarity. We further analyzed connections among within each community using three (network mean, centrality, k-core). Finally, clustering results evaluated basis...
Simultaneous optimization of material selection and structure is important for antennas, but it remains a difficult problem. To maintain the simplicity in structure, an adaptive discrete variable approach proposed differential evolution algorithm to optimize design problems with mixed variables effectively. For demonstration, based (ADVSDE) was adopted practical problems. The results show that can effectively parameters, which cannot be handled by existing algorithms.
Abstract Precipitation is a fundamental element of hydrological analyses, water resource management, and drought monitoring. To obtain high-spatiotemporal-resolution precipitation information, in this study, we proposed merging method to integrate four satellite products (i.e., the Tropical Rainfall Measuring Mission (TRMM) Multisatellite 3B42 Real-Time (TMPA-3B42RT), Climate Center Morphing Technique (CMORPH), Global Satellite Mapping Near-Real-Time (GSMaP_NRT) Estimation from Remotely...
Orthogonal frequency division multiplexing (OFDM) is the preferred scheme for high-speed communication in field of underwater acoustic communication. However, it very sensitive to carrier offset (CFO). This study used a time-varying CFO estimation method aided by differential evolution (DE) algorithm accurately estimate an OFDM system. was based on principle that received signal with inter-carrier interference could be considered Multi Carrier-code multiple access (MC-CDMA) system receiver...
Remote sensing technique is soundly used in water quality monitoring since it can receive area radiation information at the same time. But more than 80% radiance detected by sensors top of atmosphere contributed not directly body. Water seriously confused atmospheric molecular and aerosol scattering absorption. A slight bias evaluation for influence deduce large error evaluation. To inverse composition accurately we have to separate air firstly. In this paper, studied on correction methods...
Optimization of electromagnetic device design with mixed discrete and continuous variables is a challenge, especially for those high-dimensional variables. An orthogonal adaptive variable selection based differential evolution (OADVSDE) proposed to solve such problems in this paper. Continuous use the canonical algorithm perform genetic operations, while are processed mainly two steps. The first step conducted by using experimental sample small number representative combinations. Then good...
