Aged cable segments in underground power distribution systems will gradually develop into severe faults. The location of aged segment is essential for ensuring system reliability and reducing maintenance cost, but rarely studied by the existing research. In this article, a novel detection method based on wide frequency range transfer function (TF) measurement deep learning approaches proposed to fill gap. relationship between measured TF ageing parameters analyzed, two models with combined...

Achieving strong adaptability and high-load capacity for small-scale soft robots remains a challenge in current robotics engineering. In this study, inspired by snail movement, we developed crawling robot capable of controllable locomotion carrying load 204 g-7.7 times its own weight-using just one single motor control. The measures 7.6 cm length, 3 width, 2.5 height, with total weight 26.5 g. anisotropic friction mechanism on the robot's bottom, comprising origami-based pad asymmetrical...

Crowd simulation is studied extensively in computer graphics, animation, and safety. A real-time crowd simulator has been developed based on potential fields agent approach this article. This produces realistic complex heterogeneous motion improves the rates by at least 32% comparison with field results. The model of can efficiently tackle problems global optimal navigation, collision avoidance, dynamic interaction; furthermore, it allows an to make independent decisions.

There is great variation in the critical current of HTS tapes with direction applied magnetic field respect to tape surface. Based on detailed experiments, a simple analytical empirical relation density obtained. If dependence two orientations, i.e. parallel and perpendicular surface, known, we can calculate at any orientation. The calculated results are good agreement experimental data. This very useful for application magnets from practical point view.

This paper is devoted to studying some mixed radial-angular integrabilities for various types of Hausdorff operators and commutators

In this paper a new proposal of multi-functional level meter is presented. Here we have developed structure sensor with four electrodes thus it called as parallel-plate capacitor sensor. By detecting three capacitance values, the liquid estimated. Moreover, permittivity and inclined angle container are also measured at same time. process theoretical formulas used tools. The outcome research proves that proposed can be to estimate level, in some conditions

The video coding standard H.264/AVC is adopted to multimedia communications due its high compression efficiency. efficiency of H.264 mainly acquired from the newly allowed prediction schemes including variable block mode. However these require very complexity select optimal Direct-Current (DC) coefficient represents main energy signal. In this paper, a fast mode decision algorithm, called DC-based Fast Mode Decision (DC-FMD), has been presented reduce procedure for Predictive-Frame based on...

Under the influence of anthropogenic and climate, lake basins have undergone varying degrees degradation (VDD), primarily manifested in transformation land use type fluctuations carbon storage. However, accurate assessment effects VDD on storage remains a challenge. In this study, four with were selected based community characteristics vegetation coverage. Based method support vector machine (SVM) to classify basins. The cover changes (LUCC) quantified, their between 2000 2020 evaluated...

This study was conducted to develop an appropriate assessment technique define impact of mountain-desert-oasis ecosystem on net primary productivity (NPP) in northern foothills Tianshan Mountains. Geographic Information System (GIS) used estimate land use/land cover the mountain, desert and oasis zones. An ecological process model NPP by using data entirely derived from satellite. The results show that landscape heterogeneity important factor affect values ecosystem. Simulated indicated a...

Crowd simulator is extensively studied in bioinformatics, computer graphics etc.. A novel real-time crowd based on potential fields under complex environment has been proposed this paper, which makes use of static local field, dynamic collision avoidance field and global to deal with avoidance, interaction optimal navigation. Simulation results have shown that the model not only produces realistic crowds behavior but also improves simulation rate achieved by recent about 20%.

Xinjiang is rich in natural resources. The fast economic growth recent decades imposes pressure on environment. We used the material flow index to investigate impacts of development environment and explored strategies for sustainable development. Results show that still at a stage cost high consumption In terms resources usage, economy not efficient. increase primary products raises serious problems Higher level should be encouraged future

In this paper, the author make up a way of dividing whole remote sensing image into sub images to classify type vegetation. There are different types vegetation in geographic unit. So according geographical region feature image, is divided several images, less than image. Types graphic easy be showed, threshold classifying has wide scope, with assistance Digital Elevation model (DEM) and slope maps, classification accurateness was improved. This applied Xinjiang north, we hold NDVI...

Based on aerial images the GIS technique supported by ARC/INFO software was used to analyze oasis-desert landscape heterogeneity and its dynamics of Fukang transect with spatial scale change, using structural indices reveal compare characteristics heterogeneity, which useful study process through time from different aspect in arid area, heterogeneity. The results show that studied area controlled combination environment human dimension activities, natural vegetation succession. mutation,...

In the process of structured light three-dimensional measurement, absolute phase can be obtained from wrapped and period value K. The K directly determines quality point cloud. This paper proposes a novel fringe encoding decoding scheme, which quickly accurately solve phase: it only needs to project four patterns recover phase. method calculates high-frequency based on two sinusoidal patterns, then uses step pattern uniform calculate phase, Experimental tests show that proposed is accurate...
