Abstract Data-driven, model-free analytics are natural choices for discovery and forecasting of complex, nonlinear systems. Methods that operate in the system state-space require either an explicit multidimensional state-space, or, one approximated from available observations. Since observational data frequently sampled with noise, it is possible noise can corrupt representation degrading analy...

the critical properties of a solute are required for modeling of the solubility by the equation of state. for many compounds, the critical properties are not available. so, group contribution method is utilized as a common method to estimate these properties. but, it leads to the consecutive errors in calculations of the solubility modeling. in this study, soave-redlish-kowang (srk) and peng-ro...

The expansion of the settlement trough is an important factor in the risk assessment of the tunneling induced settlement. The increase of settlement trough requires buildings to be included in the impact zone, which causes damages. This paper conducts estimation of the settlement trough width (STW) using empirical approaches, field measurement data and numerical solutions. The credibility of th...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

In this article, the accuracy of empirical and numerical methods in prediction of wind wave characteristics in AmirAbad and Bushehr Ports have been studied, evaluated and compared. First, the wave characteristics have been calculated using Babolsar and Bushehr synoptic stations and employing empirical methods including SMB, SPM and CEM. Moreover the errors of empirical methods have been determi...

in this work the kinetic data demanded for kinetic modeling were obtained in temperatures 350, 400, 450 and 500 oc by conducting experimentations on a fe-cr nanocatalyst prepared from a novel method and a commercial fe-cr-cu one. the collected data were subjected to kinetic modeling by using two models derived from redox and associative mechanisms as well as an empirical one. the coefficients o...
