Orbital angular momentum (OAM) holographic technology has made advancements in the field of optical information encryption. In order to further enhance security capabilities and encryption quality, this paper proposes an technique based on a chiral vortex beam. Four keys are implemented, shared key is introduced by using multiplexing multichiral beam, which extends application range OAM A coding method discrete displacement phase modulation proposed, enabling pattern separation spatial...
Most existing dynamic simultaneous localization and mapping (SLAM) systems simply remove objects, resulting in the loss of object motion information that helps system itself localize navigate. Aiming at above problems, a visual inertial (VI) tracking SLAM tightly coupled is proposed. First, method for classifying static feature points proposed to solve problem objects cannot be extracted by learning-based or vision-only methods. Second, accurately extracts tracks rigid-body scene through...
This paper proposes a spectral clustering method using k-means and weighted Mahalanobis distance (Referred to as MDLSC) enhance the degree of correlation between data points improve accuracy Laplacian matrix eigenvectors. First, we used coefficient weight calculate any two constructed set; then, based on matrix, K-nearest neighborhood (KNN) algorithm construct similarity matrix. Secondly, regularized was calculated according normalized decomposed, feature space for obtained. fully considered...
In dynamic environments, most simultaneous localization and mapping (SLAM) methods face challenges due to potential erroneous data associations caused by the movement of objects possibility incorrect loop closures when move out field view. To address this issue, we proposed RDP-SLAM, a real-time SLAM method based on integration inertial measurement unit (IMU) segmentation. approach, novel model was developed for calculating moving probability feature points using IMU data, allowing...
We present a new approach, kernel regression, to determine photometric redshifts for 399,929 galaxies in the Fifth Data Release of Sloan Digital Sky Survey (SDSS). In our case, regression is weighted average spectral neighbors query point, where higher weights are associated with points that closer point. One important design decision when using choice bandwidth. apply 10-fold cross-validation choose optimal bandwidth, which obtained as error approaches minimum. The experiments show...
It also offers a theoretical foundation for arc fault detection technology, which is necessary to achieve the effective of faults. In order study static volt-current characteristics an and effects resistance, electrical mains voltage, on stability, fundamental features are used as basis this article. A model then created. Analyzed arc's dynamic properties under AC power frequencies well voltage current phase line during frequency half-cycle.
The growing global demand for water and energy has created an urgent necessity precise forecasting management of these resources, especially in urban regions where population growth economic development are intensifying consumption. Shenzhen, a rapidly expanding megacity China, exemplifies this trend, with its requirements anticipated to rise further the upcoming years. This research proposes innovative Convolutional Neural Network (CNN) technique consumption considering intricate...
In response to the issue of cracks in insulating substrate during installation process a specific commercial module, influence frame structure on stress was investigated. By establishing finite element model, parameters such as distance D from reinforcement ribs center screw mounting hole, number ribs, and T (referred segment difference hereinafter) between bottom surface area heat sink were studied. The results indicate that thicker or smaller D, higher experienced by installation....
