Time Series Analysis of Fine Particulates Matter (PM2.5) in Chaoyang District of Beijing
… the Box-Jenkins method to build a SARIMA model (Seasonal Autoregressive Integrated Moving Average). The results showed the PM2.5 concentration decreased from 2010 to 2012. The 24-hour PM2.5 concentration was 294μg/m³, ranged from 265.2μg/m³ to 318.5μg/m³. And the annual PM2.5 concentration was …

Preemptive variation reduction in biologic drug substance manufacturing
… this hypothesis, a digital twin for a generic Integrated Continuous Bioreactor (ICB) operation was developed based on first principles. Additionally, soft sensors were used for the real-time estimation of biomass concentration (a critical parameter in mammalian cell culture). Combining …

Responding to traveling patients' seasonal demands for health care services in the Veterans Health Administration
… Health care providers within VHA report large seasonal variation in the demand for services, especially in healthcare systems located in the southern U.S. that experience a large influx of "snowbirds" during the winter. Since the majority of resource allocation activities are carried out …

Detecting Irregular Energy Consumption Through Analytical Techniques
… heavily influenced by the presence of multiple seasonalities and heteroskedasticity. Most established time series methods were developed on the assumption that the errors are<br/>homoskedastic, hence the prediction limits that are created from such established method will often fail in detecting …
