Planning the Emergency Collision Avoidance Strategy Based on Personal Zones for Safe Human‐Machine Interaction in Smart Cyber‐Physical System
Complexity - Tập 2022 Số 1 - 2022
Thanh Phương Nguyễn, Hung T. Nguyen, Ha Quang Thinh Ngo
Human contact is a key issue in social interactions for autonomous systems since robots are increasingly appearing everywhere, which has led to a higher risk of conflict. Particularly in the real world, collisions between humans and machines may result in catastrophic accidents or damaged goods. In this paper, a novel stop strategy related to autonomous systems is proposed. This control me...... hiện toàn bộ
Lập kế hoạch chiến lược tránh va chạm khẩn cấp dựa trên vùng cá nhân cho tương tác an toàn giữa người và máy trong hệ thống vật lý ảo thông minh Dịch bởi AI
Complexity - - 2022
Nguyen, Thanh Phuong, Nguyen, Hung, Thinh Ngo, Ha Quang
Sự tiếp xúc giữa con người là một vấn đề chính trong các tương tác xã hội đối với các hệ thống tự động, bởi vì robot đang ngày càng xuất hiện ở khắp nơi, điều này dẫn đến nguy cơ xung đột cao hơn. Đặc biệt trong thế giới thực, các va chạm giữa con người và máy móc có thể dẫn đến các tai nạn thảm khốc hoặc hàng hóa bị hư hại. Bài báo này đề xuất một chiến lược dừng mới liên quan đến các hệ thống tự...... hiện toàn bộ

China’s New Environmental Protection Law and Green Innovation: Evidence from Prefecture‐Level Cities
Complexity - Tập 2021 Số 1 - 2021
Wen Chen, Ying Wu
This paper examines the impact of China’s new environmental protection law on green innovation. Using a large sample of Chinese prefecture‐level cities for the 2010–2016 period and the difference‐in‐differences (DID) methodology, we provide strong evidence that the new environmental protection law promotes green innovation. This finding is robust to a battery of sensitivity tests. The micr...... hiện toàn bộ
Global chaos synchronization of new chaotic system using linear active control
Complexity - Tập 21 Số 1 - Trang 379-386 - 2015
Israr Ahmad, Azizan Saaban, Adyda Ibrahim, Mohammad Shahzad
Chaos synchronization is a procedure where one chaotic oscillator is forced to adjust the properties of another chaotic oscillator for all future states. This research paper studies and investigates the global chaos synchronization problem of two identical chaotic systems and two non‐identical chaotic systems using the linear active control technique. Based on the Lyapunov stability theory...... hiện toàn bộ
Biotic complexity of population dynamics
Complexity - Tập 13 Số 4 - Trang 47-55 - 2008
Héctor Sabelli, Lazar Kovacevic
AbstractChanges in population size of animal species (lynx, muskrat, beaver, salmon, and fox), show diversification, episodic patterns in recurrence plots, novelty, nonrandom complexity, and asymmetric statistical distribution. These features of creativity characterize bios, a nonstationary pattern generated by bipolar feedback and multi‐agent predator–prey simulat...... hiện toàn bộ
Learning Force‐Relevant Skills from Human Demonstration
Complexity - Tập 2019 Số 1 - 2019
Xiao Gao, Jie Ling, Xiaohui Xiao, Miao Li
Many human manipulation skills are force relevant, such as opening a bottle cap and assembling furniture. However, it is still a difficult task to endow a robot with these skills, which largely is due to the complexity of the representation and planning of these skills. This paper presents a learning‐based approach of transferring force‐relevant skills from human demonstration to a robot. ...... hiện toàn bộ
Compound Autoregressive Network for Prediction of Multivariate Time Series
Complexity - Tập 2019 Số 1 - 2019
Yuting Bai, Xue‐Bo Jin, Xiaoyi Wang, Tingli Su, Jianlei Kong, Yutian Lu
The prediction information has effects on the emergency prevention and advanced control in various complex systems. There are obvious nonlinear, nonstationary, and complicated characteristics in the time series. Moreover, multiple variables in the time‐series impact on each other to make the prediction more difficult. Then, a solution of time‐series prediction for the multivariate was expl...... hiện toàn bộ
A new hybrid algorithm based on optimal fuzzy controller in multimachine power system
Complexity - Tập 21 Số 1 - Trang 78-93 - 2015
Noradin Ghadimi
In this article, a new methodology based on fuzzy proportional‐integral‐derivative (PID) controller is proposed to damp low frequency oscillation in multimachine power system where the parameters of proposed controller are optimized offline automatically by hybrid genetic algorithm (GA) and particle swarm optimization (PSO) techniques. This newly proposed method is more efficient because i...... hiện toàn bộ
Optimal preventive maintenance policy for electric power distribution systems based on the fuzzy AHP methods
Complexity - Tập 21 Số 6 - Trang 70-88 - 2016
Mansour Hosseini Firouz, Noradin Ghadimi
In power distribution systems, with their great vastness and various outage causes, one of the most important problems of power distribution companies is to select a suitable maintenance strategy of system elements and method of financial planning for the maintenance of system elements with the two objectives of decrease in outage costs and improvement of system reliability. In this articl...... hiện toàn bộ
A new method for probabilistic assessments in power systems, combining monte carlo and stochastic‐algebraic methods
Complexity - Tập 21 Số 2 - Trang 100-110 - 2015
Alireza Noruzi, Tohid Banki, Oveis Abedinia, Noradin Ghadimi
This article discusses a new methodology, which combines two efficient methods known as Monte Carlo (MC) and Stochastic‐algebraic (SA) methods for stochastic analyses and probabilistic assessments in electric power systems. The main idea is to use the advantages of each former method to cover the blind spots of the other. This new method is more efficient and more accurate than SA method a...... hiện toàn bộ
