The informs suppliers total order quantity, namely Q, based demand forecast ahead selling season. manufacture products according to predicted quantity. When actual has been observed, conducts learning determines Under assumption that are one-way substitutable, an...

The 2021 fire season in Greece was the worst of past 13 years, resulting more than 130,000 ha burnt area, with about 70% consumed by five wildfires that ignited and spread early August. Common to these occurrence violent pyroconvection. This work presents a meteorological analysis this outbreak extreme pyroconvective wildfires. Our shows dry warm antecedent weather preconditioned fuels fire-aff...

BACKGROUND Annual influenza epidemics significantly burden health care. Anticipating them allows for timely preparation. The Scientific Institute of Public Health in Belgium (WIV-ISP) monitors the incidence of influenza and influenza-like illnesses (ILIs) and reports on a weekly basis. General practitioners working in out-of-hour cooperatives (OOH GPCs) register diagnoses of ILIs in an instantl...

[1] A quantitative definition of and ability to predict the onset and duration of the dominant rainfall season in a region are important for agricultural and natural resources management. In this paper, a methodology based on an analysis of daily rainfall occurrence is proposed and applied to define the onset and end of the rainfall season in northeast Brazil. Multiple rainfall gauges are consi...

Nonparametric time-varying regression methods were developed to forecast daily ragweed pollen concentration, and the probability of the exceedance of a given concentration threshold 1 day ahead. Five-day and 10-day predictions of the start and end of the pollen season were also addressed with a nonparametric regression technique combining regression analysis with the method of temperature sum. ...

The article, using the each ten day’s data of NOAA/AVHRR from 1981 to 2000 and adopting the Maximum-Slope Method and Curve-Fitting Method, analyzes the beginning and ending of the growth season of the vegetations in the Huanghe-Huaihe-Haihe (HHH) zone. Meanwhile, the pixel by pixel NDVI map is worked out with typical bands as the sample. The article, through researching on the change of green w...

Abstract Integrated atmospheric water vapor transport (IVT) is a determinant of global precipitation. In this paper, using the CERA-20C climate reanalysis dataset, we explore three questions in Northern Hemisphere precipitation for four seasons: 1) What covariability between leading spatiotemporal modes seasonal sea surface temperature (SST), IVT, and Hemisphere? 2) How well can spatial be reco...
