With the development of automated logistics systems, flexible manufacture systems (FMS) and unmanned factories, application guided vehicle (AGV) gradually become more important to improve production efficiency automatism for enterprises. The AGV play an role in reducing labor cost, improving working conditions, unifying information flow logistics. Path planning has been a key issue control system. In this paper, two problems, shortest time path collision multi have solved. An improved A-Star...
Abstract In wartime scenarios where global navigation satellite system (GNSS) may be compromised, the cumulative errors associated with inertial systems (INSs) can lead to significant positional deviations during long-distance of drones. To address this issue, study proposes an innovative vision-inertial interactive autonomous positioning algorithm that integrates visual measurement unit-based methods, aiming achieve enhanced robustness and optimal accuracy. The first implements adaptive...
The Simultaneous Multiple Surface (SMS) method in planar geometry (2D) is applied to imaging designs, generating lenses that compare well with aplanatic designs.When the merit function utilizes image quality over entire field (not just paraxial), SMS strategy superior.In fact, traditional approach actually a particular case of strategy.
Background: Oxytropis ochrocephala Bunge, an indigenous locoweed species in China, poses great threats to livestock on grasslands. There is a need for further genetic study the plants per se, understanding basis of its acclimation mechanism various unfavorable environmental conditions and implement effective control measures. Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) most commonly used method gene expression analysis. To facilitate studies obtain more...
The gearbox is one of the most important components in a wind turbine (WT) system, and fault diagnosis WT for maintenance cost reduction paramount importance. However, feature identification primary challenge because weak features are always obscured by heavy background noise multiple harmonic interferences. In this paper, dual-enhanced sparse decomposition (DESD) method proposed to address enhancement vibration signal. Within method, nonconvex generalized minimax-concave (GMC) penalty used...
Research in covariance structure analysis suggests that nonnormal data will invalidate chi‐square tests and produce erroneous standard errors. However, much remains unknown about the extent to conditions under which highly skewed kurtotic can affect parameter estimates, errors, fit indices. Using actual varying sample sizes estimation methods, we found (a) normal theory maximum likelihood (ML) generalized least squares estimators were fairly consistent almost identical, (b) errors tended...
An interpolation method is proposed for generating the intermediate contours between a start contour and goal contour. Coupled with display voxel-based objects, it provides powerful tool reconstructing 3D object from serial cross sections. The tries to fill in lost information two slices, assuming that there smooth change them. This reasonable assumption provided sampling at least twice Nyquist rate, which case result of expected be very close reality. One major advantages this approach its...

Such anomaly trades always inference with in By cluster information such anomalies, effectively really world Experiment...
This paper develops a new approach to band selection for multiple-target detection, called constrained-target (CTBS). Its idea is derived from the concept of constrained energy minimization (CEM) by constraining target interest, while minimizing variance resulting background (BKG). By taking advantage CEM, produced interest can be further used as measure prioritizing bands well means selecting this particular target. As result, two CTBS-based prioritization (BP) criteria, minimal...
Different from the ground image with uniform haze, haze in remote sensing (RS) has characteristics of irregular shape and uneven concentration hazy weather. It brings a great challenge to application RS data advanced processing tasks. A novel dehazing network for non-uniform image, named as KFA-Net, is proposed solve aforementioned issues. The designed asymmetric size feature cascade (ASFC), k-means pixel attention (KPA) FFT channel (FCA) KFA-Net all show excellent effects. Compared...
An improved method for automatically reconstructing a three-dimensional object from serial cross sections is presented. The improves the dynamic elastic contour interpolation technique. There are two major improvements: (1) in case of branching that involves concave contours, instead pairwise between start and each goal contour, image considered globally local constraints imposed on forces exerting upon vertices; (2) it takes continuity high-order derivatives into consideration incorporates...
The cubic-spline interpolation (CSI) scheme can be utilized to obtain a better quality reconstructed image. It is based on the least-squares method with cubic convolution (CCI) function.

Cooperative coevolution (CC) has shown great potential for solving large-scale optimization problems (LSOPs). However, traditional CC algorithms often waste part of the computation resource (CR) as they equally allocate CR among all subproblems. The recently developed contribution-based improve ones to a certain extent by adaptively allocating according some heuristic rules. Different from existing works, this paper explicitly constructs mathematical model allocation (CRA) problem in and...
