long time series
To reveal the sector structure, an algorithm for estimating trends of long time series is proposed.
      
Linear drift and periodic variations observed in long time series of polar motion
      
Two long time series were analysed: the C01 series of the International Earth Rotation Service and the pole series obtained by re-analysis of the classical astronomical observations using the HIPPARCOS reference frame.
      
Since the works by the business cycle theorists in the 1930s, no attempts have been made to study empirically the long term evolution paths of individual technologies starting with long time series.
      
Results of a long time series of nonmethane hydrocarbons and halogenated hydrocarbons measurements at three differently polluted sites in the FRG are presented.
      
A long time series of bi-weekly samples at 0.5?mab, lasting 1.5?years, indicated a doubling of the biomass during the night with no apparent seasonality.
      
The procedure is rapid, and can be continued across the boundary of the domain, for example, when the data is a long time series which must be artificially broken into "image" blocks for computer processing.
      
Segmentation algorithm for long time series analysis
      
Long time series of ground-based plant phenology, as well as more than two decades of satellite-derived phenological metrics, are currently available to assess the impacts of climate variability and trends on terrestrial vegetation.
      
To look at the ocean's response to orbital forcing we take the long time series generated from our paleoclimatic proxies and calculate their spectrum over a fixed, but sliding, time window.
      
Annual cycles in long time series of precipitation from sixteen southwest European observatories have been analysed using complex demodulation.
      
Many wildlife-monitoring programmes have long time series of species abundance that cannot be summarized adequately by linear trend lines.
      
To describe long time series better, generalized additive models may be used to obtain a smooth trend line through abundance data.
      
Dynamic Detection of Change Points in Long Time Series
      
The evaluation of the photodiode records in the form of long time series was founded upon the fast Fourier transform, especially on the analysis of phase angle shifts between signals coming from photodiode pairs situated along the plasma flow.

They demonstrate the necessity for using long time series monitoring results to assess change and evaluate the effects of climate change on the North Sea coastal ecosystems, using ecosystem models on decadal time scales.
      
At each site, we collected several, weeks-long time series of hydrography, current velocity, and acoustic backscatter due to mesozooplankton.
      
A year-long time series of dissolved oxygen data indicated a negative relationship between hyacinth abundance and dissolved oxygen concentrations.
      
While these procedures are well suited for very long time series, it is difficult to adopt the rules for time series of special observation periods with higher resolution in time.
