To explore the relationship between the prices of shipping market and China's economy, this paper analyzes the data of BDI and China's GDP from 2000 to 2015. By stabilizing the BDI and GDP data, this paper identifies the one-way causal relationship between the BDI and China's GDP via the granger causality test. The conclusion shows that BDI effects China's GDP positively at rate of 22% by using...

In this paper, the required measurement time to measure a transfer function with a specified accuracy is analyzed. The waiting time that is needed to balance the transient induced errors against the noise errors is calculated. This allows one to decide under what conditions broad-band measurements are faster than stepped sine measurements.

Introduction: The central-governor model explains the mechanism of endurance exercise-induced central fatigue, but high-intensity exercise-induced central fatigue has not been investigated yet. This study aimed to research how central fatigue during high-intensity intermittent pedaling alters the neural response, which results in electroencephalography (EEG) recordings. Methods: We assessed ne...

In Technical Report EE98024, the authors present a closed-form expression for the quan-tiication of model error in transfer function estimation by characterising undermodelling by a random walk process in the frequency domain. The present note shows that, for systems with resonant modes, less conservative model error quantiications may be obtained by alternatively characterising undermodelling ...

Results of transfer function analysis for a class of distributed parameter systems described by dissipative hyperbolic partial differential equations defined on a one-dimensional spatial domain are presented. For the case of two boundary inputs, the closed-form expressions for the individual elements of the 2×2 transfer function matrix are derived both in the exponential and in the hyperbolic f...

in this paper we present a method to perform flood frequency analysis (ffa) when the assumption of stationary is not important (or not valid). a wavelet transform model is developed to ffa. a full series is applied to ffa using two different wavelet functions, and then a combined method is investigated. in the combined method, all discharge data which were less than the lowest value of annual m...

the present study was conducted in the rangeland of glandrood watershed in the province of mazandaran. the objective of this study was to compare between the ecological amplitude of festuca ovina l., and poa bulbosa l., using the function hof along the gradient of the environmental variables. for this purpose 150 plots of 1m2 were established along the altitude gradient. the sampling method was...
