The extraction and classification of crops is the core issue agricultural remote sensing. precise crop types great significance to monitoring evaluation planting area, growth, yield. Based on Google Earth Engine Colab cloud platform, this study takes typical oasis area Xiangride Town, Qinghai Province, as an example. It compares traditional machine learning (random forest, RF), object-oriented (object-oriented, OO), deep neural networks (DNN), which proposes a random forest combined with...
Abstract The Junggar Basin is rich in oil but lacks natural gas, which inconsistent with its geological background of gas. Based on the analysis main source kitchens, and evaluation setting controlling factors gas accumulation, it proposed that three significant fields for exploration should be emphasized. first field Carboniferous volcanic rocks. residual sags large-scale reservoirs were developed active continental margins, i.e., southeastern, northeastern northwestern margins. Gas...
A reverse-flow combustor has a larger liner surface area due to airflow turning, which complicates flow and cooling control, particularly heat transfer efficiency. Effective management is essential for maintaining uniform temperature distribution preventing thermal gradients. This study explores the impact of axial position diameter primary holes on performance dynamics. Results indicate that as move toward dome, recirculation vortex size decreases, leading insufficient fuel mixing,...
First, we briefly review the atmospheric chemistry and previous intercomparison measurements for HCHO, with special reference to diffusion scrubber Hantzsch reaction based fluorescence instrument used in field studies reported herein. Then discuss summertime HCHO levels five major U.S. cities measured over 1999−2002, primarily from ground-based measurements. Land−sea breeze circulations play a role observed concentrations coastal cities. Very high peak mixing ratios were Houston (>47 ppb)...
The intensification of anthropogenic activities has led to the infiltration enormous quantities pollutants into rivers and lakes, resulting in significant deterioration water quality a more prominent occurrence eutrophication. Poyang Lake, largest freshwater lake China, is facing severe challenge related eutrophication, which seriously threatens delivery ecosystem service safety drinking water. To address this challenge, Landsat-8 Operational Land Imager (OLI) data for Lake Basin (PLB) from...
Abstract A new automated instrument for the near–real‐time measurement of atmospheric formaldehyde is described. The chemistry involves cyclization reaction with 1,3‐cyclohexanedione (CHD) in presence ammonium ions to form a fluorescent dihydropyridine derivative. GaN‐based light‐emitting diode (LED) emitting near UV was used as excitation source miniature flowthrough fluorescence detector based on transversely illuminated liquid‐core waveguide. configured operate periodic autozero mode...
HJ-2 (Huanjing-2) was launched in September 2020. It has a charge-coupled device (CCD) that offers spatial resolution of 16 m and revisiting time two days, making it an excellent option for environmental disaster monitoring. However, more evaluation is needed the ability CCD to monitor water quality. As chlorophyll concentration (CChla) main indicator quality evaluation, this study, performance sensor CChla been verified, with particular focus on typical eutrophic lakes. The essential...
In this letter, a new method is proposed to enhance the ground-penetrating radar (GPR) signal for time-delay estimation in low signal-to-noise ratio. It based on subspace and clustering technique. The makes it possible improve accuracy noisy context. used with compressive sensing estimate time delay of layered media backscattered echoes coming from GPR signal. Several simulations an experiment are presented show effectiveness enhancement.
