M. Szega, W. Stanek Silesian University of Technology, Gliwice, Poland L. Blacha Silesian University of Technology, Katowice, Poland The reduction of energy consumption in the blast furnace is still the subject of investigations using mathematical modelling of a blast furnace plant. Theoretical-empirical hybrid models of a blast furnace and its equipment have been presented. This model is built...

In this work, a Genetic Algorithm boosted Least Square Support Vector Machine model by a set of linear equations instead of a quadratic program, which is improved version of Support Vector Machine model, was used for estimation of 98 pure compounds second virial coefficient. Compounds were classified to the different groups. Finest parameters were obtained by Genetic Algorithm method ...

Support vector machine (SVM) has been successfully applied for cancer tumor classification based on thousands of gene expression measurements. A modification of SVM known as hybrid Huberized support vector machine (HHSVM) has been developed for the same purpose along with an in built gene selection mechanism with the help of elastic-net penalty. In this paper we develop a Bayesian formulation o...

Most models used in land surface hydrology, vadose zone hydrology, and hydro-climatology require an accurate representation of soil thermal properties (soil thermal conductivity and volumetric heat capacity). Various empirical relations have been suggested to estimate soil thermal properties. However, they require many input parameters such as soil texture, mineralogical composition, porosity a...

This research applied Fuzzy Delphi Analytic Hierarchy Process (FDAHP) to evaluate the critical success factors for New Product Development (NPD) by using a hybrid vehicle as an example. Grey Relational Analysis (GRA) is used to assess the level of gray relation among these factors, followed by empirical analysis to construct the NPD strategy. The empirical result illustrates that the indicators...

shear wave velocity is a basic engineering tool required to define dynamic properties of soils. in many instances it may be preferable to determine vs indirectly by common in-situ tests, such as the standard penetration test. many empirical correlations based on the standard penetration test are broadly classified as regression techniques. however, no rigorous procedure has been published for c...

there are different studies in urban literature on the determinants of urban growth, from the theoretical and empirical points of view. the most completed theoretical model is henderson model (1988, 1997, and 1999), which is tested by some empirical studies. as henderson model shows, the set of national product, specialization and technological progress are the determinants of urban growth. usi...
