WiFi is widely used for indoor positioning because of its advantages such as long transmission distance and ease use indoors. To improve the accuracy robustness fingerprint localization technology, this paper proposes a system CCPos (CADE-CNN Positioning), which based on convolutional denoising autoencoder (CDAE) neural network (CNN). In offline stage, applies K-means algorithm to extract validation set from all-training set. online RSSI first denoised key features are extracted by CDAE....
Most of the current visual Simultaneous Localization and Mapping (SLAM) algorithms are designed based on assumption a static environment, their robustness accuracy in dynamic environment do not behave well. The reason is that moving objects scene will cause mismatch features pose estimation process, which further affects its positioning mapping accuracy. In meantime, three-dimensional semantic map plays key role mobile robot navigation, path planning, other tasks. this paper, we present...
Ecosystem service research is essential to identify the contribution of ecosystem human welfare. As an important ecological barrier zone, Kubuqi Desert supports use a crucial wind erosion prevention (WEPS) improve environment quality. Based on Revised Wind Erosion Equation (RWEQ) model, spatial and temporal changes WEPS in region were simulated from 2000 2022, impacts interactions natural socio-economic factors including numerical typological variables pattern sand control services analyzed...
In indoor highly dynamic scenes or with missing a priori information, most current schemes cannot effectively avoid the impact of moving objects on performance SLAM (Simultaneous Localization and Mapping) systems. order to solve problem accurate localization map building for mobile robots in environments, we propose RGB-D visual dense method based pyramidal L-K (Lucas-Kanade) optical flow multi-view geometric constraints. Our proposed consists three stages: object culling, camera position...
We propose a new SLAM method based on fast simultaneous localization and mapping (FastSLAM). The technique presented uses an improved quantum-behaved particles swarm optimization (QPSO) to improve the proposal distribution of optimize estimated particles. This makes sampled closer true pose robot improves estimation accuracy poses landmarks. In QPSO algorithm, Gaussian disturbance is added increase diversity By using this premature convergence overcome. resample step, threshold value used...
This paper presents the design of a linear phase superconducting filter with quasi-elliptic response. The coupling structure contains two trisections and one quadruplet. are applied to generate independent transmission zeros for high selectivity realized by meandered open-loop microstrip resonators; quadruplet is equalization four novel L-shaped resonators. designed at 1950 MHz bandwidth 20 MHz. It fabricated on LaAlO3 wafer double-coated Tl2Ba2CaCu2O8 films. shows good together flat group...
In this paper, a 30 dB broadband microstrip directional coupler is designed by using discrete coding type coupling structure with co-simulation technique. Combined the proposed hybrid binary particle swarm genetic optimization algorithm (HBPSGOA) and carefully fitness function, can provide satisfactory flexibility excellent performance. For fixed design space, space firstly be encoded mapped to corresponding matrix, then optimal matrix searched HBPSGOA will used high directivity. The...
This article is concerned with the prediction of time delays and a control method for networked systems (NCSs). We propose to predict network-induced online least squares support vector machines (LSSVM) optimized by particle swarm optimization (PSO). Then self-tuning proportional–integral–derivative (PID) variable adopted in NCSs. The recursive (RLS) used identify parameters controlled objects, which can adapt changes dynamic models. Simulations verified excellent performance network delay...
Self-constructing feedback fuzzy neural network controller (SCFFNNC) is designed to aim at the parameter uncertainties for permanent magnet linear synchronous motor (PMLSM) since they cause negative influence dynamic performance of PMLSM servo system. The thought about self-constructing, in which number neurons whole structure can be able increase on line according variety error, introduced based combining non-linear identification control with self-learning network. It reserve abilities,...
A quadruple-mode dual-wideband filter is proposed in this paper.

Successful excitation attributed to probes. first wide-passband realized by second achieved TE+ mode. Finally, designed, fabricated measured. measurements good agreement with...
This paper presents an edge vision SLAM system based on bilateral filtering and adaptive thresholding. is a complete including visual odometry, sliding window optimization, cyclic closure that can be built out of semi-dense maps. At the heart approach use thresholding to retain as much information possible combine images with depth mapping for joint camera pose estimation, further increasing stability in poorly textured environments. The front-end odometry module estimates relative motion...
