Abstract-This paper presents the various methods for the spectral analysis of signals for the stationary as well as non-stationary signals. Due to non-stationary characteristics of the signals, it has been always a challenge to achieve time frequency distribution of such signals. Between the various techniques of signal analysis, this paper uses Fourier transform, Short time Fourier transform, ...

the prime objective of the study is to identify the long-run and short-run relationship between indian stock price viz., bse sensex (hereafter named as bse) and gold price (gold) in india. the daily closing price data were collected for the period of ten years ranging from 1st april 2004 to 31st march 2014 with 2490 observations. the study employed two models: model one used gold as dependent v...

The early cytokines production in response to live logarithmic and stationary phase promastigotes of Leishmania major was examined on the peripheral blood cells of the healthy individuals. Whole blood cultures were stimulated by either logarithmic or stationary phase promastigotes. IFN- and IL-10 productions were assessed by specific sandwich ELISA. The results showed that the logarithmic prom...

Model specification of short–range dependent stationary time series has become a very active research field in both econometrics and statistics since about two decades ago. In the meantime, estimation of long–range dependent stationary time series models has also been quite active. To the best of our knowledge, however, model specification of stationary time series with long–range dependence (L...

[Purpose] The objective of this study was to investigate the effects of stationary cycling exercise on the balance and gait abilities of chronic stroke patients. [Subjects] Thirty-two chronic stroke patients were randomly assigned to an experimental group (n=16) or a control group (n=16). [Methods] All of the subjects received the standard rehabilitation program for 30 minutes, while the experi...

This paper describes a new test designed in subcritical fluid chromatography (SFC) to compare the commercial C18 stationary phase properties. This test provides, from a single analysis of carotenoid pigments, the absolute hydrophobicity, the silanol activity and the steric separation factor of the ODS stationary phases. Both the choice of the analytical conditions and the validation of the info...

This paper proposes a simple testing procedure to detect the presence of nonlinear but global stationary logistic smooth transition autoregressive processes. This testing procedure nests the one developed by Kapetanios et al. (2003) that accommodates specifically the alternative of a global stationary ESTAR process. The present work makes a threefold contribution to the literature. First, it de...
