Understanding the relationships between snow and vegetation is important for interpretation of responses alpine ecosystems to climate changes. The Qinghai-Tibetan Plateau regarded as an ideal area due its undisturbed features with low population relatively high cover. We used 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) datasets during 2001–2010 examine snow–vegetation relationships, specifically, (1) influence melting date on green-up (2) effects cover duration greenness....
Vegetation is the functional subject in wetland ecosystem and plays an irreplaceable role biodiversity conservation. It of great significance to monitor vegetation for scientific assessment impact on ecological environment biodiversity. In this paper, a method extracting based short time series Normalized Difference Index (NDVI) data set was constructed. First, NDVI were constructed using Sentinel-2 images. Then, Support Vector Machine (SVM) classifier used classify types. The distributions...
Abrading is a very important sub-technology of the surface treatment technology with vast applications in industry. This study aims at analyzing inherent laws friction systems during abrading. In particle flow code modeling, abrading process can be simplified to movement particles parallel-plate shear system. this study, PFC2D software used construct system set parallel plates and model parameters according processing equipment materials, control simulation single variable, compare output...
Abstract Petroleum geologists have debated whether the hydrocarbons from Jurassic coal measures are derived coals, carbonaceous mudstones or coal‐measure in Turpan Basin. Based on geochemistry analysis of 20 crude oils and 40 source rocks Basin, some data been obtained as follows: carbon preference index methylphenanthrene 1.16–1.45 0.28–0.80, ααα C 29 sterane 20S/(20S+20R) ββ/(ββ+αα) 0.44–0.51 0.4–0.54 respectively, which show normal maturity oils; vitrinite reflectance Xishanyao to...
Abstract Synthetic Aperture Radar (SAR) can monitor rice regardless of time and weather condition, the ability crop lodge monitoring has been demonstrated by previous studies. However, there have no study about lodging using satellite-based SAR. In this study, we extracted backscatter coefficient (BC) H/A/Alpha polarimetric parameters from dual-polarized Sentinel-1 SAR data, a sensitivity factor γ was constructed for selecting optimal radar feature parameter (ORFP) which is highly to rice....
The low strength and large protrusion of the traditional dieless clinched joint hindered its application. To improve mechanical properties joint, a novel clinching process considering limitation blank holder was proposed. finite element model established by DEFORM-2D, influences spring stiffness, limit height, punch diameter on interlock were analyzed, influence laws stiffness height material flow obtained. Then, these three die parameters their interaction analyzed using response surface...
In this article, considering the characteristics of nonlinearity, time-variables, and disturbance in hydraulic roll-bending system, a generalized predictive control scheme based on time series prediction error compensation was proposed. A model used to compensate future sequence error, which not only made system have strong anti-interference robustness, but also improved target tracking accuracy stability system. The algorithm simplified by introducing increment attenuation factors into...
Height is an important indicator of rice growth condition and phenological period. The Polarimetric SAR Interferometry (PolInSAR) has proven a valuable technique for providing structural metrics vegetation. Anechoic chamber experiments, allowing high flexibility in the configuration operating parameters, such as frequency baseline, most convenient feasible way to study potential PolInSAR height retrieval. In this study, first measurements recently built anechoic chamber, Laboratory Target...
The use of lightweight sheets such as carbon fiber reinforced composites (CFRP), magnesium alloys, and aluminum alloys is great significance to realize the automobiles. However, differences between make joining processes dissimilar a challenge. A pre-holed screw-drilling riveting (PH-SDR) process proposed based on study existing processes, rivet with threads riveted into by rotating, effective achieved embedding threads. joint strength PH-SDR self-piercing (SPR) was compared through...
The average level of indoor radon concentration for the residence in uranium ore district is 282Bq/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and maximum value can up to 570Bq/m which exceed national top limited (200Bq/m ). Indoor pollution very serious. In order find out reason pollution, main environmental factors are investigated. Through calculations Gaussian atmospheric diffusion model simulation verification it found that...
Aimed at the relatively large error of traditional models rolling load, a new Rolling Load Prediction Finishing Stands method is set up by Fuzzy Identification. It based on T-S fuzzy model using triangle-shaped membership functions to calculate grade for each given pattern, and Kalman filtering identify consequent parameters model. So prediction precision load improved. On basis measured data 1580 mm hot strip mill, relation between main mill established Experimental results show that...
Fractured-vuggy carbonate reservoirs have complex pore structure, significant heterogeneity, and irregular permeability-porosity relation, which make existing evaluation methods unable to accurately calculate the permeability. To investigate seepage characteristics of rocks with triple-porosity, 3D digital rock models were constructed from X-ray computed tomography (CT) scanning images cores collected in field, physical properties obtained by combining analysis (DRA) nuclear magnetic...
