Land use and land cover (LULC) classification is essential for understanding the impact of both human activities and natural processes on the Earth’s surface. This classification plays a critical role in deforestation, urban planning, and damage assessment. However, traditional machine learning techniques often face challenges in achieving consistent accuracy in diverse datasets. In this study, we implement transfer learning and Bayesian learning approaches to enhance the accuracy and robustness of LULC classification. Transfer learning leverages knowledge from previous classification problems, while Bayesian learning addresses uncertainties in the classification process. Using the Remote Sensing Image Classification Benchmark (RSI-CB128) dataset, the study evaluates the performance of Bayesian Convolutional Neural Networks (CNN), Mobile Neural Networks (MobileNet), Inception Neural Networks (InceptionNet), Densely Connected Convolutional Networks (DenseNet) and Efficient Neural Networks (EfficientNet). The study also investigates the impact of varying the Bayesian layers on model performance, finding that a medium number of layers optimally captures model uncertainty. The results indicate that the transfer learning models, particularly MobileNet, achieved the highest accuracy of 97. 48% compared to 90. 33% for Bayesian CNN. These findings suggest that transfer learning techniques are highly effective for LULC classification, providing a reliable method for practical applications in remote sensing.

The security of mobile robotic networks (MRNs) has been an active research topic in recent years. This paper aims to secure the ubiquitous formation control of MRNs against the replacement attack, where an external robot can replace a formation robot by compromising the communication and physically interfering with the victim simultaneously. To counter this advanced attack, the novel idea of this work is to leverage the physical proximity of the formation shape and the interaction topology among robots for defense design. First, from the physical proximity perspective, we propose the convex neighbor polygon (CNP) to capture the geometric characteristic of the formation robots, and design a CNP-based security mechanism for the robots during the replacement attack. Then, from the interaction perspective, we introduce the indirect controllability to characterize the possibility that the attacker leverages the interaction between robots to deactivate the CNP mechanism, and establish the conditions regarding the topology structure and the attack input to counter the replacement. Finally, based on the obtained conditions, we demonstrate how to design the initiatory topology among the formation robots to enhance the defense performance. Comparative simulations verify the effectiveness of the proposed method. © 1963-2012 IEEE.

This paper presents a congestion detection system for routers in Network-on-Chip (NoC) architectures based on fuzzy logic methods. The system uses the average buffer occupancy of routers, the packet injection rate (PIR), and the betweenness centrality (BC) metric as input parameters. The proposed method enables the prediction of router congestion probabilities. The paper also constructs network congestion heatmaps for various PIR values. The conducted studies demonstrate the effectiveness of the approach for early congestion detection, opening opportunities for dynamic traffic management and adaptive routing protocol optimization in NoC systems.

Three kinds of methods for processing the data of the multi-wavelength pyrometer are presented in this paper and are named curve auto-search method, curve auto-regression method and neural network method. Tbe experimental results indicate that the calculated temperature and the spectral emissivity compared with the true target temperature and spectral emissivity have significant deviation using the curve auto-search and the curve auto-regression methods. However, the calculated temperature and the spectral emissivity with higher accuracy can be obtained using the neural network method.

Permanent magnet synchronous motors (PMSMs) are widely used in industry due to their high torque per volume ratio, low noise, efficiency and wide stable operation region. Especially in home appliance applications, obtaining high torque using small motors and low audible noise has crucial importance. Therefore, conventional DC motors have been replaced by the permanent magnet synchronous motors in the modern applications. In this study, field oriented sensorless control over wide speed range is carried out under parametric uncertainties. The pole coloring concept is used for the control of a PMSM in an industrial setup for the first time. The design method and experimental results are presented. © 2017

Error compensation on precision machine tool servo control system based on digital concave filter

引用

Journal of Harbin Institute of Technology(New Series) 2001年第4期8卷 389-393页

作者：王立松苏宝库张晶董申 Dept. of Control Theory and Engineering Harbin Institute of Technology Dept. of Computer Science and Engineering Harbin Institute of Technology Dept. of Mechanical Engineering and Automation Harbin Institute of Technology

It is concluded from the results of testing the frequency characteristics of the sub micron precision machine tool servo control system, that the existence of several oscillating modalities is the main factor that affects the performance of the control system. To compensate for this effect,several concave filters are utilized in the system to improve the control accuracy. The feasibility of compensating for several oscillating modalities with a single concave filter is also studied. By applying a modified Butterworth concave filter to the practical system, the maximum stable state output error remains under ±10 nm in the closed loop positioning system.

Scheduling a three-machine no-wait flowshop with separated setup time

In many practical flowshop production environments, there is no intermediate storage space available to keep partially completed jobs between any two machines. The workflow has to be continuous, implying that the no-wait conditions must be abided, which is typical in steel and plastic production. We discuss the three-machine no-wait flowshop scheduling problem where the setup times are considered as separated from processing times and sequence independent. The scheduling goal is to minimize the total flowtime. An optimal property and two heuristic algorithms for this problem are proposed. Evaluated over a large number of problems, the proposed heuristics are found that they can yield good solutions effectively with low computational complexity, and have more obvious advantage for the large size problem compared with the existing one.

Path planning of free-floating robot in cartesian space using direct kinematics

International Journal of Advanced Robotic Systems 2007年第1期4卷 17-26页

Dynamic singularities make it difficult to plan the Cartesian path of free-floating robot. In order to avoid its effect, the direct kinematic equations are used for path planning in the paper. Here, the joint position, rate and acceleration are bounded. Firstly, the joint trajectories are parameterized by polynomial or sinusoidal functions. And the two parametric functions are compared in details. It is the first contribution of the paper that polynomial functions can be used when the joint angles are limited (In the similar work of other researchers, only sinusoidla functions could be used). Secondly, the joint functions are normalized and the system of equations about the parameters is established by integrating the differential kinematics equations. Normalization is another contribution of the paper. After normalization, the boundary of the parameters is determined beforehand, and the general criterion to assign the initial guess of the unknown parameters is supplied. The criterion is independent on the planning conditions such as the total time tf. Finally, the parametes are solved by the iterative Newtonian method. Modification of tf may not result in the recalculation of the parameters. Simulation results verify the path planning method.

In the process industry, engineering functions for the administration and optimization of devices are gaining importance in comparison with process control functions. Thus, the term 'asset optimization' is often used to describe techniques that exploit the full potential of plant assets. This applies in particular to field devices used in production processes. This paper presents the asset management box (AMBOX) which is an open, configuration-free and manufacturer-independent access to field device functionality for the Profibus-PA Fieldbus, creating an additional information channel between field and plant control level.

The degree of machine automation is continuously increasing, because computer technology, control software, telecommunication technology and visualization systems are also continuously improved. This makes the use of new multimedia techniques for reading, communication and presentation of machine or process data possible, even over far distances. Multimedia communication is becoming a technology of growing importance for user interfaces in automation and process control. Think of acoustic and visual data obtained from microphones or cameras applied to a certain automated system. They can be simply used and understood as a new brand of sensors or actuators that are part of a process control unit. Supervising and monitoring of certain process states is simplified, if the operator can "see" and "hear" the real process. Technical aspects concerning types, quality and speed of multimedia data communication will be discussed and especially viewed for an implementation in automated systems. © 2002 IEEE.
