Abstract: The time series data were experimented for Unit-Root. This test normally conducted to ascertain the time series stationarity and to agree on the array of assimilation of the variables. It is obligatory to conduct the Unit-Root test for the rationale that the trouble of variables with non-stationary producing spurious or meaningless effects due to the occurrence of trend in the data series. This testing procedure is completed by means of the Unit-Root testing methodology. In this paper stationarity assessed for the data collected for the purpose of studying the impact of exchange rate

Abstract:
The stationarity test of vibration signals is critical for the extraction of the signal features. In this article, the surrogate data with various time–frequency analysis methods are proposed for stationary test of vibration signals. The surrogate data are first generated from the Fourier spectrum of the original signal with keeping the magnitude of the spectrum unchanged and replacing its phase by a random sequence. The local and global spectra of the original signal and the surrogate data are then estimated by four time–frequency analysis methods, which are short-time Fourier transform, mult

Abstract:
We investigate the stationarity property of the accumulated Ethernet traffic series. We applied several widely used stationarity and unit root tests, such as Dickey-Fuller test and its augmented version, Phillips-Perron test, as well as the Kwiatkowski-Phillips-Schmidt-Shin test and some of its generalizations, to the assessment of the stationarity of the traffic traces at the different time scales. The quantitative results in this research provide evidence that when the time scale increases, the accumulated traffic series are more stationary.

With the continuous accumulation of theoretical knowledge and progressive applied research, analyzing financial time series data gradually becomes everlasting research in modern days. The simpler Dickey-Fuller originally is a test commonly used in econo-metrics and finance to test the stationarity of financial time series data. Thereafter, simpler Dickey-Fuller is eventually extended to the augmented Dickey-Fuller test to examine the stationarity of financial time series data such as stock prices, returns, and so on.

We propose a method to identify stationary phases in time series. Stationarity is a necessary condition for many concepts in dynamical systems theory, e.g. deterministic chaos. Therefore, testing for stationarity should necessarily be the first step in any data analysis. Above all, this testing is highly important whenever one deals with systems for which stationarity is not guaranteed by the data acquisition procedure: if only short and unique time series are accessible and if the experimental situation is not or only restrictedly controllable, as for instance in astronomy, economy, or medici

Abstract:
Traditionally, stationarity refers to shift invariance of the distribution of a stochastic process. In this paper, we rediscover stationarity as a path property instead of a distributional property. More precisely, we characterize a set of paths, denoted by A, which corresponds to the notion of stationarity. On one hand, the set A is shown to be large enough, so that for any stationary process, almost all of its paths are in A. On the other hand, we prove that any path in A will behave in the optimal way under any stationarity test satisfying some mild conditions.

This note analyzes the empirical size of the augmented Dickey and Fuller (ADF) statistic proposedby Perron and Rodríguez (2003) when the errors are fractional. This ADF is based on a searching procedure for additive outliers based on first-differences of the data named td. Simulations show that empirical size of the ADF is not affected by fractional errors confirming the claim of Perron and Rodríguez (2003) that the procedure td is robust to departures of the unit root framework. In particular the results show low sensitivity of the size of the ADF statistic respect to the fractional parameter

Abstract:
New keynesian Phillips curve (NKPC) has become a central model to study the relation between inflation and real economic activity, notably in the framework of optimal monetary policy design. However, some recent evidence suggests that empirical data are usually at odds with the underlying theory. The model due to its inherent structure represents a statistical challenge in its own right. Since Galí and Gertler (1999) published their seminal paper introducing estimation via GMM techniques, they have triggered a heated debate on its empirical relevance. Their approach has been heavily criticised

We are interested in the stochastic properties, individual and joint, of mis- specification testing when the data are generated by an autoregressive process. Good mis-specification tests are invariant to the dynamic properties of the pro- cess summarized by its characteristic roots, and to irrelevant misspecifications. Invariance in parameter space obviates inference prior to mis-specification test- ing. This is important as the latter is used to validate the former. Mutual independence of the tests allows calibration of the overall significance level. Es- tablishing such results requires work

Abstract:
This seminar provides a hands-on exploration of time-series methods useful for econometrics as well as social and health science research. Any modelling exercise involving time series data depends crucially on the correct treatment of any non-stationarity which may be present in the data. The seminar explores the developments in dynamic modelling and non-stationarity which have taken place over the last 50 years in Econometrics, including in-depth coverage types of non-stationarity and tests for them, including cointegrated relationships (shared trends) among multiple variables.

Abstract:
A unified theory of estimation and inference is developed for an autoregressive process with root in (-∞, ∞) that includes the stationary, local-to-unity, explosive and all intermediate regions. The discontinuity of the limit distribution of the t-statistic outside the stationary region and its dependence on the distribution of the innovations in the explosive regions (-∞, -1) ∪ (1, ∞) are addressed simultaneously. A novel estimation procedure, based on a data-driven combination of a near-stationary and a mildly explosive artificially constructed instrument, delivers mixed-Gaussian limit theor

Full text
Abstract:
Liquid contamination in dry gas seals (DGS) can come from a variety of sources, including lube oil carryover and liquid dropout, due to the Joule-Thompson effect across the seal faces, which can cause DGS failure. The physical effect of liquids on DGS performance is a topic of limited understanding, and conflicting theories exist regarding liquid-induced failure mechanisms. While tests have been performed on DGS test rigs (primarily by seal OEMs), very little testing or analysis has been specifically aimed at studying the heat generation behind DGS behavior following liquid injection, and test

Abstract:
In 1972, PRCI Project PR-15-61 was initiated to measure exhaust emissions from stationary reciprocating gas engines and gas turbines used in natural gas compressor stations. Emission rates of oxides of nitrogen (NOx), hydrocarbons (HC), and carbon monoxide (CO) were measured from 59 reciprocating gas engines and nine gas turbines. During and subsequent to 1972, the PRCI laboratories and various PRCI member companies conducted emissions measurements. In 1978, PRCI Project PR-15-92 was initiated to conduct additional emissions measurements. That project involved 55 reciprocating gas engines and

Full text
Abstract:
To maintain measurement accuracy, stationary volume provers must be re-proved periodically. The most direct method of determining a provers volume is through a process known as water drawing where water is circulated through the prover and swept into certified measurement volumes. Since the can volumes can be directly calibrated by national metrology agencies, the traceability chain is short. However, proving with water requires that the prover be first cleaned of any hydrocarbon product that may alter the working volume of the prover and create waste products that must be handled properly.

Abstract:
The project objective was to demonstrate the feasibility of a pipeline right-of-way defense system based on a suite of stationary sensors mounted on, and adjacent to, the pipeline. The sensor data from multiple locations along the pipe are wirelessly forwarded to a central location for further analysis. Analytics residing at a central location correlate the data from multiple sensors to alert operators to events of interest occurring in the ROW with minimal latency. The purpose of this project is to design, test, and demonstrate in the field a system that automatically monitors the right-of-wa
