The shear behavior of backfill-rock composites is crucial for mine safety and the management surface subsidence. For exposing failure mechanism composites, we conducted tests on under three constant normal loads, compared with unfilled rock. To investigate macro- meso-failure characteristics samples in tests, cracking was recorded by a high-speed camera acoustic emission monitoring. In parallel experimental test, numerical models rock were established using discrete element method to analyze...

Remote predictions of the nitrogen nutrition index (NNI) are useful for precise (N) management in field. Several studies have recommended two methods estimating NNI, which classified as mechanistic and semi-empirical this study. However, no been conducted to thoroughly analyze compare these methods. Using winter wheat an example, study compared performances NNI determine method is more suitable practical use. Field measurements were above ground biomass, N concentration canopy spectra during...

The reaction force observer (RFOB) is susceptible to interference and struggles estimate accurate forces in bilateral control systems. This paper proposes a novel method for the estimation of micro over large stroke range based on macro-micro drive system. further applied control. macro actuator comprises motor characterized by inherent friction, while utilizes voice coil (VCM) that offers small with friction-less. Through dynamic modeling, elastic caused flexible hinges coupling between...

To prevent potentially unsuitable activities during vegetation restoration, it is important to examine the impact of historical restoration on target ecological system inform future policies. Taking Loess Plateau China as an example, a regionalization method and corresponding scheme were proposed select suitable types (forested lands, woody grasslands/bushlands, grasslands, or xerophytic shrublands semi-shrublands) for given location using remote sensing technology in order analyze growth...

Data assimilation is a robust method to predict crop biophysical and biochemical parameters. However, no previous study has attempted grain protein content (GPC) at regional scale using this method. This explored the feasibility of designing an model for wheat GPC estimation remote sensing, growth model, priori knowledge. The data included field experiment sampling data, Landsat Operational Land Imager images were employed, with CERES (Crop Environment REsource Synthesis)-Wheat used as...

The remote sensing based Production Efficiency Models (PEMs), springs from the concept of "Light Use Efficiency" and has been applied more in estimating terrestrial Net Primary Productivity (NPP) regionally globally. However, global NPP estimates vary greatly among different models data sources handling methods. Because direct observation or measurement is unavailable at scale, precision reliability cannot be guaranteed. Though, there are ways to improve accuracy input parameters. In this...

Oil–gas–water multiphase flows are widely used in petrochemical, biochemical, food chemical, mineral engineering and energy engineering. In this paper, the double-ring conductivity probe double-helical capacitance were extended to water fraction measurement of oil–gas–water flow vertical pipe. The test pipe section riser was designed. experiment, self-designed corresponding signal processing circuit measure three-phase flow. dynamic calibration carried out under working condition high...

In this paper, the characteristics of forced convection heat transfer in water-based nanofluids are studied by means experimental and theoretical analysis. Nusselt number were calculated changing volume fraction type nanoparticles tube. The effects Reynolds on studied. An exergy analytical model was established for laminar nanofluid under condition constant flow. At same condition, friction entropy production flow process tube increases with addition nanoparticles, decreases at time....
