14. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

15. Indicator kriging applied to RMR geomechanical modelling in a Pb-Zn deposit case study
Abstract The opening of a mining enterprise requires knowledge of the geomechanical characteristics of the mineral deposit, which will be worked according to the use of parameters of stability and/or resistance of the material, as well as the discontinuities present in the rock. In this study, the Rock Mass Rating methodology was used to propose a geomechani

17. Effect of a boomerang-shaped Conchal cartilage graft for Type three Tympanoplasty on Hearing
Abstract Introduction Chronic suppurative otitis media atticoantral disease (CSOM-AAD) is often associated with ossicular erosion resulting in significant hearing loss. Absence of the stapes suprastructure is a poor prognostic indicator of hearing outcome, which necessitates an effective reconstruction technique for ossicular continuity and restoration of m

20. MONITORING TRACTOR PERFORMANCE USING SHEWHART AND EXPONENTIALLY WEIGHTED MOVING AVERAGE CHARTS
ABSTRACT Statistical process control has been widely used in agricultural operations for monitoring and improving process quality. This study aims to evaluate the Shewhart and exponentially weighted moving average (EWMA) control charts to monitor the performance of an agricultural tractor–planter set. The design is completely randomized based on the assump
