Entropy-Based Pattern Learning Based on Singular Spectrum Analysis Components for Assessment of Physiological Signals
Complexity - Tập 2020 - Trang 1-17 - 2020
Measures of predictability in physiological signals based on entropy metrics
have been widely used in the application domain of medical assessment and
clinical diagnosis. In this paper, we propose a new entropy-based pattern
learning by a combination of singular spectrum analysis (SSA) and entropy
measures for assessment of physiological signals. Physiological signals are
first represented as a se...
BRWSP: Predicting circRNA‐Disease Associations Based on Biased Random Walk to Search Paths on a Multiple Heterogeneous Network
Complexity - Tập 2019 Số 1 - 2019
The circular RNAs (circRNAs) have significant effects on a variety of biological
processes, the dysfunction of which is closely related to the emergence and
development of diseases. Therefore, identification of circRNA‐disease
associations will contribute to analysing the pathogenesis of diseases. Here, we
present a computational model called BRWSP to predict circRNA‐disease
associations, which se...
Compound Autoregressive Network for Prediction of Multivariate Time Series
Complexity - Tập 2019 Số 1 - 2019
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 explored in
...
The virtues and vices of equilibrium and the future of financial economics
Complexity - Tập 14 Số 3 - Trang 11-38 - 2009
AbstractThe use of equilibrium models in economics springs from the desire for
parsimonious models of economic phenomena that take human reasoning into
account. This approach has been the cornerstone of modern economic theory. We
explain why this is so, extolling the virtues of equilibrium theory; then we
present a critique and describe why this approach is inherently limited, and why
economics ne...
Global chaos synchronization of new chaotic system using linear active control
Complexity - Tập 21 Số 1 - Trang 379-386 - 2015
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 and
usi...
China’s New Environmental Protection Law and Green Innovation: Evidence from Prefecture‐Level Cities
Complexity - Tập 2021 Số 1 - 2021
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
micromechani...
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
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...

A new hybrid algorithm based on optimal fuzzy controller in multimachine power system
Complexity - Tập 21 Số 1 - Trang 78-93 - 2015
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 it cope w...
Optimal preventive maintenance policy for electric power distribution systems based on the fuzzy AHP methods
Complexity - Tập 21 Số 6 - Trang 70-88 - 2016
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 article, a pra...
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
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 and
also ...
