As an indispensable material for animals, plants and human beings, obtaining accurate water body information rapidly is of great significance to maintain the balance ecosystems ensure normal production life beings. Due its independence time day weather conditions, synthetic aperture radar (SAR) data have been increasingly applied in extraction bodies. However, there a deal speckle noise SAR images, which seriously affect accuracy water. At present, most processing methods are filtering...
Abstract The concept of combinatorial p th Calabi flow is proposed for finding circle packing metrics with prescribed curvatures. It has been studied under the Euclidean and hyperbolic background geometries. This study investigates total geodesic curvatures spherical geometry. established that flow, subject to given geometry, exists all time <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:mi>t</m:mi> <m:mo>∈</m:mo> <m:mrow> <m:mo>[</m:mo> <m:mn>0</m:mn> <m:mo>,</m:mo> <m:mo>+</m:mo>...
China's rural reform is reliant on farmers' cooperatives as a key organization vehicle. It plays an important role in promoting revitalization. Such as, realizing the organic connection between small farmers and agricultural modernization. This study used nearest neighbor index kernel density estimation to analyze spatial distribution structural characteristics of farmer Hunan Province. revealed differentiation law cooperatives. Also using geographical detectors figure out main factors that...
Fraudulent claim detection is one of the greatest challenges insurance industry faces. Alibaba's return-freight insurance, providing return-shipping postage compensations over product return on e-commerce platform, receives thousands potentially fraudulent claims everyday. Such deliberate abuse policy could lead to heavy financial losses. In order detect and prevent claims, we developed a novel data-driven procedure identify groups organized fraudsters, major contributions losses, by...
The mixed pixel of low-resolution remote-sensing image makes the traditional water extraction method not effective for small body extraction. This study takes Loess Plateau with complex terrain as research area and develops a multi-index fusion threshold segmentation algorithm (MFTSA) large-scale based on GEE (Google Earth Engine). MFTSA uses AWEI (automated index), MNDWI (modified normalized difference NDVI (normalized vegetation index) EVI (enhanced synergy to extract bodies. It also slope...
Hydraulic cavitation is usually an undesirable phenomenon since it can damage the concrete surface of a chute spillway. In order to numerically predict potential high‐speed flow in spillway, compound risk assessment proposed by combining probabilistic analysis with computational fluid dynamics (CFD) technique. Based on local pressure and velocity nodes, traditional number introduced characterize possibility cavitation. The distribution numbers was obtained according numerical simulation...
Abstract The Mekong Delta, South East Asia's ‘rice bowl’, sustains more than 18 million people through its agricultural output. This yield is secured by efficient water management systems but susceptible to climatic changes. As Vietnam's policies aim optimize the delta's semi‐mountainous regions reliant on rain‐fed agriculture, this study investigates drought risks and climate change impacts runoff in O Ta Soc Tuk Sa reservoirs, An Giang Province, Vietnam. Using simulation models, we...
Abstract Soundless cracking technique has been widely applied in the demolition of rock and concrete structures because its cleaner advantages compared with conventional explosive methods. However, correlations between fracturing processes characteristics soundless agents (SCDAs) optimal use SCDA improving efficiency are still poorly documented. In this concern, study develops a reliable numerical model verified by experimental data to investigate fragmentations based on extended finite...
Since the Ms 8.0 earthquake occurred in Yingxiu, a town Wenchuan County Sichuan Province, on May 12, 2008, frequent geological disasters ensued land affected by earthquakes Longmenshan fault zone have caused large number of casualties and property losses. Therefore, measuring disaster resilience earthquake-stricken areas is priority for prevention mitigation science. Based in-depth analysis hazard resilience, this paper constructs compatibility coefficient industrial employment structure per...
Abstract Affordability of water services is an important part the UN's sustainable development goals (SDGs), especially for a highly populated, developing country such as China. Previous studies have mainly focussed on unique index systems, from different perspectives affordability evaluation, while large‐scale at national level are rare, and understanding still not complete scientific. In this study, functional cost‐price model coupled with assessment system comprehensive evaluation method...
The accurate and efficient estimation of bed roughness using limited historical observational data is well-established. This paper presents a new parameter-inversion model for estimating in hydrodynamic models that constrains the distribution between river sections. impact various factors on accuracy inversed was analyzed through numerical experiment with number measurement stations, observed amount, initial roughness, noise, weight regularization term. results indicate increasing stations...
Abstract An integrated multi‐criteria analysis framework was proposed for the sustainable water management of built reservoir with dam‐heightening‐based decision, which enhances conventional decision‐making methods by more reasonably quantifying process. The method utilizes a group techniques involving game theory, analytic hierarchy process (AHP) identifying and considering different stakeholder groups, entropy weight, fuzzy comprehensive evaluation (GAEF), is applied to largest transfer...
Due to the causes of excessively underground mining, increased land surface loading and water extractions etc., subsidence becomes a global serious problem damaging buildings, roads highways, flood-control structures etc. More more new technologies such as GNSS are used monitor subsidence. Analysis monitoring data plays important role since it helps interpret current phenomena predict future scenarios. Principal Component (PCA) is an effective tool for spatio-temporal filtering extracting...
To mitigate the instability problem of heavy equipment foundations in deep coal mine chambers under high geo-stress, this study proposes a combined reinforcement strategy for foundation pits, which are mainly composed pipe piles and split-level vertical cables. The weak rock mass around pit is reinforced using cables grouting. split-level-arranged with different lengths improve tensional strength mass, whereas pile at corner can enhance shear strength. overall performance structure terms...
