A Modular Approach for The Diagnostic Analysis of Dynamic Systems Using Time Series Models

IFAC Proceedings Volumes, 1982
Abstract In many dynamic systems such as aircrafts, space vehicles, nuclear power plants and magnetohydrodynamic generators, it is often necessary to determine the cause of fluctuations in a primary variable as a function of dynamic inputs to the system and other process variables. The timely detection of the source of anomaly in the system is useful

Analytical Sensitivities of Principal Components in Time-Series Analysis of Dynamical Systems

AIAA Journal, 2010
original method for calculating the analytical sensitivities of the principal components of dynamical systems is developed. Methods for analytical sensitivity calculations are developed for both the singular-value decomposition and eigenanalysis-based approaches for principal component calculation. Sensitivities with respect to state initial conditions

Applications of Neural-Network Algorithms to Nonlinear Time Series Analysis of Dynamical Optical Systems

Nonlinear Dynamics in Optical Systems, 1990
The techniques of prediction and modeling using a neural network algorithm, preceded by application of noise reduction methods, are shown to be applicable to time series associated with nonlinear dynamical optical systems. The time series generated from a generic dynamical model is used to train a backpropagation, feed forward neural network which is ...

Hegemony, Long Waves, and Major Wars: A Time Series Analysis of Systemic Dynamics, 1496-1967

International Studies Quarterly, 1991
In both systemic and realist theories, hegemons are expected to deter major intra-core wars that would upset their favored position in the status quo. Yet the conceptions, measures, and units of analysis for hegemony differ within and between the theoretical perspectives.

Prediction system of economic crisis in Indonesia using time series analysis and system dynamic optimized by genetic algorithm

2012 International Conference on System Engineering and Technology (ICSET), 2012
Economic crisis that had happened at 1997–1998 in Indonesia has stimulated researchers to study it further by utilizing economic indicators. The economic indicators, GDP (Gross Domestic Product) and inflation per year from 1980–2011, will be tested using time series analysis and system dynamic optimized by genetic algorithm.

Coupling analysis in time series using information theory and dynamical systems theory

2017
Inferring causality from observations of different entities is central to science. Time series is an important form of observations in subjects ranging from physics, geology and medicine to finance. Although non-experimental observations such as time series measured from geological entities and financial markets are in general never sufficient for ...

Dynamic systems analysis for better hospital bed operation: using time series model.

Medinfo. MEDINFO, 1996
Achieving high efficiency in hospital bed operations becomes an important aim of hospital management, as managerial environment of hospitals has been increasingly competitive in Korea. Many authors have made studies on higher occupancies, but very few about systems characteristics of the time serial data as well as decision behavior on bed operations ...
