This paper aims to use Si29 nuclear magnetic resonance (NMR) for investigating the effect of nanofillers on C-S-H gel structure hardened cement paste, analyze modification mechanism from a microscopic perspective, and then provide fundamentals controlling macroscopic properties cement-based materials. Different curing temperatures (25°C 90°C) nanofiller types [including nano-SiO2, nano-ZrO2, nano-TiO2, carbon nanotubes (CNTs), nano-boron nitride (nano-BN), multilayer graphenes (MLGs)] are...
The study presented in this paper aims to investigate the self-healing properties of reactive powder concrete (RPC) modified with nanofillers, which has ability compressive and flexural strength. inner damage RPC nanofillers during loading is analyzed by using an acoustic emission system. Three types (nano-SiO2, nano-TiO2 nano-ZrO2) two curing methods (water air curing) are selected for identifying influencing factors. Experimental results indicate that all incorporated have enhance RPC....
This paper studies the influence of mix proportion and processing method on mechanical electrical properties nano/fiber fillers filled cementitious composites. Cementitious composites with different contents filler, superplasticizer (SP), ultrasonic energy or mixing speeds are fabricated. Experimental results indicate that optimal content nano-silica (NS), carbon nanotube (CNT) fiber (CF) is 0.1%, 0.1% 1% by weight cement, respectively, when water/cement ratio (w/c) 0.2 SP 0.75 wt%. Compared...
Simultaneous localization and mapping (SLAM) is the technological basis of environmental sensing, it has been widely applied to autonomous navigation. In combination with deep learning methods, dynamic SLAM algorithms have emerged provide a certain stability accuracy in scenes. However, robustness existing are relatively low scenes, their performance affected by potential objects fast-moving objects. To solve positioning interference caused these objects, this study proposes geometric...
Due to the long distance and large-scale of satellite imaging, high complexity depth convolutional neural network, common detectors cannot be directly applied remote sensing images. Therefore, this article proposes a two-phase object detection network from key points region proposals, namely P2RNet. In first phase, all suspected objects are obtained through point extraction then these divided into multiple proposals using proposal generator. second input lightweight achieve fast accurate...
There are two sources of depth information in a stereo pair. One is the correlation signal from smooth surface regions that visible to both eyes, which provides via triangulation. The other decorrelation near occluding contours, about locations and amplitudes discontinuities by half-occlusions they induce. A variety perceptual stimuli have convincingly demonstrated active roles signals stereopsis. In computational vision, there has been less progress using signal. For example, one common...
Abstract: In order to meet the requirement of natural gas hydrate pressure preserving exploration, a pressure-preserving coring technology for seafloor drill is introduced. The mathematical model predicting change water in drilling tool established solve low core collection rate during process. relationship between drainage path parameters tools and variation degree inside clarified. design criteria are formed. valve spool structural determined verified by field application. results show...
