  Development of Attenuation Relationships for Underground Blasts: Different Equations

  By Saha Dauji

  Abstract: Blasting operation becomes essential for excavation in weathered and hard rock strata for construction and mining activities. The Indian Standard and industrial practice of establishing the site specific attenuation relationship recommend Power form of relationship between the PPV the scaled distance with an exponent of 2/3 (IS) and 1/2 (industrial practice). In this paper, three different equation forms and five different exponents were explored for modelling the aforementioned relationship for …

  Prediction of Compressive Strength of Concrete with Decision Trees

  By Saha Dauji

  Abstract: In the past few researchers predicted the compressive strength of concrete from its ingredients employing data driven technique like artificial neural network (ANN) and Decision Tree (DT). For Indian concrete records, only one study was available which had employed ANN for prediction. Evaluation of different performance metrics indicated that there was scope of improvement in the prediction performance. In this paper experimental data from the literature was utilized for development …
