Predictions in ungauged basins: an approach for

Nov 30, 2015 regionalization of model parameters by developing appropriate functional relationship between the parameters and basin characteristics is one of the potential approaches to employ hydrological models in ungauged basins. while this is a widely accepted procedure, the uniqueness of the watersheds and the equifinality of parameters bring lot of uncertainty in the simulations in

sep 01, 2016 sep 01, 2016 comparison of existing and proposed and ultrasonic testing machine results. in this section, casting yield was improved from 73.15% to 83.96%, feeding yield improved from 79.68% to 85.62% and gating yield improved from 83.46% to 96.34%.

these models represent a consolidation of the scientifi c understanding of the range of physical processes driving the earth system, that predict and relate knowledge useful in the policy and management decision-making processes of federal agencies and international organizations. to advance global and regional models at various scales

aug 24, 2018 aug 24, 2018 furthermore, the impacts of the predictors on the pm2.5 were assessed which the chemical precursors’ influences indicated more in comparison with meteorological parameters. capabilities of the models were compared to each other and the support vector machine was found to be the best performing, based on evaluation criteria.

additive manufacture of sand molds via binder jetting enables the casting of complex metal geometries. various material systems have been created for 3d printing of sand molds; however, a formal study of the materials’ effects on cast products has not yet been conducted. in

The models and parameters of cone crusher | hxjq

When choosing crusher machines, a comparison should be conducted according to different situations. generally, jaw crusher is used for primary crushing, and for second crushing or fine crushing, a large ore-dressing plant always chooses the cone crusher, and a medium or

sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. the sand casting process involves the use of a furnace

dec 21, 2018 dec 21, 2018 at present, the models for predicting cutting forces mainly include empirical model, numerical model, artificial intelligence model and analytical model. the empirical model is expressed as an exponential function of cutting force and process parameters, based on the statistical and regression analysis of orthogonal experimental results [ 3 ].

nov 10, 2020 nov 10, 2020 author summary identifying dengue cases early is crucial but challenging for healthcare professionals. this challenge is increased during large epidemics and is a particular problem in non-endemic areas with limited experienced staff. to improve dengue diagnosis, we investigated how to exploit machine learning (ml)-based prediction models and identified four key
