The complexity of pollutant-mixing mechanism in open channels generates large uncertainty estimation longitudinal and lateral dispersion coefficients (Kx Ky). Therefore, Kx Ky rivers should be accompanied by an analysis, a subject mainly ignored previous studies. We introduce method based on thorough analysis different calibration datasets, resampled from global database tracer studies, to dete...

Credit scoring has become a very important task as the credit industry has been experiencing severe competition during the past few years. The artificial neural network is becoming a very popular alternative in credit scoring models due to its associated memory characteristic and generalization capability. However, the relative importance of potential input variables, long training process and ...

The demand for Wireless Sensor Networks is increasing day by because of their diverse nature. Due to the limited energy, it a complex task retract sensor node after deployment. So, there requirement network maintainability before deployment phase its smooth working. It achieved in three phases: hardware node, communication and external environmental phase. This paper focuses on A novel framewor...

Machine learning methods can offer a practical alternative to deterministic and statistical methods for predicting air pollution concentrations. However, for a given data set, it is often not clear beforehand which machine learning method will yield the best prediction performance. This study compares the variable selection and prediction performance of four machine-learning methods of differen...

The monitoring of soil salinity levels is necessary for the prevention and mitigation of land degradation in arid environments. To assess the potential of remote sensing in estimating and mapping soil salinity in the El-Tina Plain, Sinai, Egypt, two predictive models were constructed based on the measured soil electrical conductivity (ECe) and laboratory soil reflectance spectra resampled to La...

The number of emergency (or unplanned) readmissions in the United Kingdom National Health Service (NHS) has been rising for many years. This trend, which is possibly related to poor patient care, places financial pressures on hospitals and on national healthcare budgets. As a result, clinicians and key decision makers (e.g. managers and commissioners) are interested in predicting patients at hi...

The aim of this study was to obtain a predictive model able to perform an early detection of central segregation severity in continuous cast steel slabs. Segregation in steel cast products is an internal defect that can be very harmful when slabs are rolled in heavy plate mills. In this research work, the central segregation was studied with success using the data mining methodology based on mu...
