Detection Method for Non-Stationary Oscillations in Process Plants
Persistent oscillations are a common problem in process plants since they cause excessive variation in process variables and may compromise the product quality. This paper proposes a method for detecting oscillations in non-stationary time series. The method is based on the statistical properties of zero-crossings and it removes the non-stationary trend component from a signal before applying a...
متن کاملA new adaptive exponential smoothing method for non-stationary time series with level shifts
Simple exponential smoothing (SES) methods are the most commonly used methods in forecasting and time series analysis. However, they are generally insensitive to non-stationary structural events such as level shifts, ramp shifts, and spikes or impulses. Similar to that of outliers in stationary time series, these non-stationary events will lead to increased level of errors in the forecasting pr...
متن کاملDetecting Correlations between Non-stationary Brain Signals
A new approach is proposed to detect instantaneous correlations between neural activity in different parts of the brain measured with extracellular multi-site recordings. With this method one can also study how the coupling between different areas changes while the animal is performing certain tasks. We illustrate this method by investigating the coupling between the two mushroom bodies of the ...
متن کاملDetecting Switches Against Non-Stationary Opponents
Interactions in multiagent systems are generally more complicated than single agent ones. Game theory provides solutions on how to act in multiple agent scenarios; however, it assumes that all agents will act rationally. Moreover, some works also assume the opponent will use a stationary strategy. These assumptions usually do not hold in real world scenarios where agents have limited capacities...
متن کاملNumerical algorithm for discrete barrier option pricing in a Black-Scholes model with stationary process
In this article, we propose a numerical algorithm for computing price of discrete single and double barrier option under the emph{Black-Scholes} model. In virtue of some general transformations, the partial differential equations of option pricing in different monitoring dates are converted into simple diffusion equations. The present method is fast compared to alterna...
