Semantic segmentation for remote sensing images (RSIs) is widely applied in geological surveys, urban resources management, and disaster monitoring. Recent solutions on tasks are generally addressed by CNN-based models transformer-based models. In particular, architecture struggles with two main problems: a high computation load inaccurate edge classification. Therefore, to overcome these problems, we propose novel transformer model realize lightweight First, based Swin backbone, pure...

Semantic segmentation is a significant method in remote sensing image (RSIs) processing and has been widely used various applications. Conventional convolutional neural network (CNN)-based semantic methods are likely to lose the spatial information feature extraction stage usually pay little attention global context information. Moreover, imbalance of category scale uncertain boundary meanwhile exists RSIs, which also brings challenging problem task. To overcome these problems,...

The actuator failure compensation control problem of robotic systems possessing dynamic uncertainties has been investigated in this paper. Control design against partial loss effectiveness (PLOE) and total (TLOE) the are considered described, respectively, a disturbance observer (DO) using neural networks is constructed to attenuate influence unknown disturbance. Regarding prescribed error bounds as time-varying constraints, method based on barrier Lyapunov function (BLF) used strictly...

Taking the plant as a total uncertainty in black box with measurable inputs and attainable outputs, this paper presents constructive control design of agnostic nonlinear dynamic systems discontinuous input (such hard nonlinearities forms dead zones, friction, backlashes). This study expands model-free sliding mode (MFSMC), based on Lyapunov differential inequality, to robust (TMFRC) for class piecewise systems, which does not use extra adaptive online data fitting modelling deal...

In this manuscript, a sliding mode control technique is proposed for multi-switching synchronization of chaotic systems in which state variables master system are synchronized with different slave system. Based on the and Lyapunov stability theory, suitable controllers designed switches. To implement methodology, Lorenz taken as Pehlivan Simulation results carried out to justify theoretical revealed that error dynamics tends zero required obtained.

Image captioning attempts to generate a description given an image, usually taking Convolutional Neural Network as the encoder extract visual features and sequence model, among which self-attention mechanism has achieved advanced progress recently, decoder descriptions. However, this predominant encoder-decoder architecture some problems be solved. On side, without semantic concepts, extracted do not make full use of image information. only relies on word representations, lacking guidance...

Nonlinear rational systems/models, also known as total nonlinear dynamic in an expression of a ratio two polynomials, have roots describing general engineering plants and chemical reaction processes. The major challenge issue the control such system is input embedded its denominator polynomials. With extensive searching, it could not find any systematic approach designing this class systems directly from model structure. This study expands U‐model‐based to establish platform for first layer...
