The carbon storage of terrestrial ecosystems is closely related to global climate change. Therefore, assessing the impact land-use changes on instructive reduce emissions. Taking an arid region in northwest China as example, this paper analyzed from 1980 2015. It used CA-Markov model predict pattern 2020 2050, and sequestration module Integrated Valuation Ecosystem Services Tradeoffs (Invest) mode assess ecosystem over past 35 years next 30 discusses ecosystems. results showed that: (1)...
Abstract. The processes of water storage have not been fully understood in different vegetation zones mountainous areas, which is the main obstacle to further understanding hydrological and improving resource assessments. To understand process soil movement (alpine meadow (AM), coniferous forest (CF), mountain grassland (MG) deciduous (DF)) this study monitored temporal spatial dynamics hydrogen- oxygen-stable isotopes precipitation Xiying River basin. results show that order evaporation...
Abstract In‐depth knowledge of the hydrological conditions basins in arid regions can help to maintain long‐term water security. The mechanisms runoff generation and flow paths different landscape areas are not fully known due spatial variability. We have explored by which variability affects recharge sources Xiying River Basin. results showed that mountain flow‐producing zone is result combined effect landscape, elevation meteorological elements. In upstream area, short mean transit time...
Early diagnosis of failures can prevent financial losses and industry downtime. In this article, the author proposes an early fault technique for rotor-bearing faults. The proposed is based on recognition sound signals. measured analyzed three states system: system under normal operating conditions, with faulty bearings, rotor friction. original feature extraction method described, namely, 1/3 doubling (a selecting amplitude frequency ratio that a multiple 30% maximum amplitude). This used...
This paper aims to address the challenge of low accuracy in single-modal driver anger recognition by introducing a multimodal model. The primary objective is develop fusion method for identifying anger, focusing on electrocardiographic (ECG) signals and driving behavior signals.
Abstract. Understanding the differences and control factors of stable water isotopes in soil–plant–atmosphere continuum (SPAC) different vegetation zones is great significance revealing hydrological processes regional cycle mechanisms. From April 2018 to October 2019, we collected 1281 samples investigated isotopes' changes SPAC three (alpine meadows, forests, arid foothills) Shiyang River basin. The results show following: (1) precipitation plays a major role SPAC. alpine meadows foothills,...
In view of the current situation that there are few studies on whether fault signals may occur in rotor bearing system can be identified and analyzed sensor arrangement, diagnosability is applied to optimal arrangement sensors system. The preliminary layout multi-sensor carried out by analyzing transmission path vibration based minimum path. Secondly, nonparametric kernel density estimation method calculates state information’s probability function. K-L divergence value further used measure...
As essential parts of various types rotor machinery, rolling element bearings are vital in connecting and support. When rotating, bearing failure is the most common reason mechanical failure. To maintain normal running components, detection extremely important. In this study, a technology for early fault diagnosis based on vibration signals was proposed, following states bearing, including faulty outer ring inner were obtained. MSAF-20- MAX (Method Selection Amplitudes Frequency-20-Maximum)...
With the rapid development of unmanned aerial vehicle technology, vehicles have been widely used to obtain ground remote sensing images. Due limited field view a single image, it is necessary stitch images large-scale scene image apply various practical applications. This paper introduces two-stage stitching algorithm combining geographic coordinate information and features. The sequence divided into intra-line inter-line stitching. Firstly, we use coordinates features calculate...
With the exponential growth of data, it becomes more and difficult to quickly obtain valuable information from massive amounts data. Clicking browsing such non-scoring implicit data has also attracted attention scholars. Recommendations for generally use bayesian personalized ranking algorithm (BPR). The focuses on difference in preferences between item pairs, believes that users prefer items have interacted with never interacted. However, this assumption is still not specific enough...
Abstract. Stable isotopes could be used as tracers to estimate the evaporation loss of surface water, which provides a new perspective for research hydrological processes. A systematic observation station has been built in Shiyang River Basin, one most important inland river basins Northwest China. This work conducted observations on precipitation and hydrometeorology from 2017 2019. The is estimated 1.30 % mountainous rivers, 2.28 reservoir (Xiying Reservoir), 2.87 oasis 7.97 (Hongyashan...
In view of the current situation that there is little research on whether possible fault signals rotor-bearing system can be identified and separated when optimizing sensor arrangement, transmission path vibration in analyzed, rolling bearing signal model established, diagnosability applied to optimal arrangement system, evaluation criterion used as an indicator evaluate different solutions. The finally given. are measured at these nodes, fast Fourier transform performed obtain spectrum...
Abstract. Understanding the differences and controlling factors of stable water isotopes in soil-plant-atmosphere continuum different vegetation zones has important guiding significance for revealing hydrological processes regional cycle mechanisms.This study selected three (alpine meadows, forests, arid piedmont zones) Shiyang River Basin study. This paper’s analysis results show that: (1) In SPAC, precipitation isotope main effect. From alpine meadows to foothills, as altitude decreases,...
