Robust versions of the exponential and Holt–Winters smoothing method for forecasting are presented. They are suitable for forecasting univariate time series in the presence of outliers. The robust exponential and Holt–Winters smoothing methods are presented as recursive updating schemes that apply the standard technique to pre-cleaned data. Both the update equation and the selection of the smoo...

For robust detection performance, traditional control chart monitoring for biosurveillance is based on input data free of trends, day-of-week effects, and other systematic behaviour. Time series forecasting methods may be used to remove this behaviour by subtracting forecasts from observations to form residuals for algorithmic input. We describe three forecast methods and compare their predicti...

This paper considers univariate online electricity demand forecasting for lead times from a half-hour-ahead to a day-ahead. A time series of demand recorded at half-hourly intervals contains more than one seasonal pattern. A within-day seasonal cycle is apparent from the similarity of the demand profile from one day to the next, and a within-week seasonal cycle is evident when one compares the ...

The article describes the method of forecasting time series of cash withdrawals in ATMs. The hybrid model is based on two methods: Holt-Winters additive method and Markov chainbased model. The combination occurs with the help of weight coefficients which are calculated on the basis of work of each model. Holt-Winters method forecasts time series with trend and seasonal variations. Markov chain ...

Prediction of incoming calls can be useful in many applications such as social networks, (personal, business) calendar and avoiding voice spam. Predicting incoming calls using just the context is a challenging task. We believe that this is a new area of research in context-aware ambient intelligence. In this paper, we propose a call prediction scheme and investigate prediction based on callers’...

A waste stabilization pond was suspected of causing fecal contamination to Holt Branch, a tributary of Juniper Creek, near Byron, Georgia. We used ribotyping, a genotypic (DNA-based) bacterial source tracking (BST) method, to match Enterococcus faecalis isolates from Holt Branch and the waste stabilization pond. Fecal enterococci in the effluent from the waste stabilization pond averaged 13,863...

Bringing to light the difference between birth and nation, the refugee causes the secret presupposition of the political domain—bare life—to appear for an instant within that domain. In this sense, the refugee is truly ‘the man of rights,’ as Arendt suggests, the first and only real appearance of rights outside the fiction of the citizen that always covers them over. Yet this is precisely what ...
