â  using of prediction models is one of the methods of financial performance prediction. financial ratios are employed as predictive variable in prediction models. the main purpose of this study is to compare the incremental information content of accrual and cash ratios for prediction and evaluation of the financial performance of business entities by data mining models. in align with research...

Abstract. A field study was undertaken to investigate the accuracy of two micrometeorological flux footprint models for calculating gas emission rate from a synthetic 10 × m surface area source, based on vertical measured at fetches 15 50 downwind source. Calculations were made with an easy-to-use tool Kormann–Meixner analytical model and more sophisticated Lagrangian stochastic dispersion mode...

In this chapter a general model for the two-phase fluid flow in porous media is presented, together with its simplified form, known as the Richards equation, which is applicable (under specific assumptions) to describe water flow in the vadose zone. In each case the governing equations are formulated at the Darcy scale, using the capillary pressure–saturation relationship and an empirical exten...
