Rockburst is a complex mining-induced phenomenon that remains difficult to be quantified.In particular, geological conditions contributing to rockbursts are more variable than those in many conventional engineering approaches.Faults, intact rock properties, and other rock mass conditions vary, sometimes, within small distance.Stress levels that sto
A novel feature reconstruction method, referred to as interval feature transformation (IFT), is proposed for time series classification.The IFT uses perceptually important points to segment the series dynamically into subsequences of unequal length, and then extract interval features from each time series subsequence as a feature vector.The IFT dis
Introduction.Indirect pulp capping is a therapeutic intervention in the treatment of deep carious lesion in order to stimulate odontoblasts to produce tertiary dentin using different biomaterials based mainly on calcium hydroxide.The aim of this study was to assess the effect of hard-setting (Dycal) and a suspension of Body Scrub calcium hydroxide
