evaluation of stochastic simulation method for generating meteorological data
abstract long-term historical weather data are needed to conduct crop simulation analysis. simulated climatic data may be used when long series of historic data are not available or convenient or when future data are needed. the aim of this study was to generate daily weather values for maximum and minimum air temperatures. a number of weather generators are compared here. data from ten station...
متن کاملForecasting Natural Gas Demand Using Meteorological Data: Neural Network Method
The need for prediction and patterns of gas consumption especially in the cold seasons is essential for consumption management and policy planning decision making. In residential and commercial uses which account for the bulk of gas consumption in the country the effects of meteorological variables have the highest impact on consumption. In the present research four variables include daily ave...
متن کاملData Mining with Meteorological Data
Prediction of the future values by analysing meteorological data is one of the important parts which can be helpful to the society as well as to the economy. Estimates of these values at a specific time of day, from daytime and daily profiles, are needed for a number of environmental, ecological, agricultural and technical applications, ranging from natural hazards assessments, crop growth fore...
متن کاملAn Efficient Sparse Data Filtering Method for Image Histogram Comparison
The traditional method for creating a color histogram is to equally subdivide a certain color space into a given number of bins and then count the number of pixels each bin contains. Using such a histogram, the performance of almost all methods of histogram comparison are highly sensitive to the localization of the bin boundaries. In order to alleviate this sensitivity a new method of histogram...
متن کاملModified Beamspace Method for the Spatial Filtering of Magnetoencephalographic Data
IntroductIon Magnetoencephalography (MEG) and electroencepha-lography (EEG) are noninvasive measurement tools that provide high temporal resolution on the units of milliseconds to investigate neuronal activity in the brain. MEG and EEG measure the magnetic fields and the scalp electrical potentials produced by the current sources, respectively. MEG systems utilize gradiometer and/or magnetomete...
