Performance evaluation of chain saw machines for dimensional stones using feasibility of neural network models
Prediction of the production rate of the cutting dimensional stone process is crucial, especially when chain saw machines are used. The cutting dimensional rock process is generally a complex issue with numerous effective factors including variable and unreliable conditions of the rocks and cutting machines. The Group Method of Data Handling (GMDH) type of neural network and Radial Basis Functi...
متن کاملMesonorms of granitic rock analyses
SINCE Cross, Iddings, Pirsson, and Washington 09o3) first published their system of deriving normative minerals from chemical analyses, the CIPW norm has been successfully used to identify, compare, and classify trends in igneous rocks with similar or differing mineral compositions. The norm has been used for metamorphic rocks and rocks of somewhat uncertain mode of origin (Bowes, ~967). Variou...
متن کاملTwo-dimensional measurement of natural radioactivity of granitic rocks by photostimulated luminescence technique
Two-dimensional measurement of radiation produced by natural irradiation of granitic rocks was performed by the use of an imaging plate, which is a storage film coated with photostimulated phosphor (BaFBr:Eu2+). Radiation images of small volume specimens, such as thin sections were obtained with the imaging plate. Irradiation images of granitic rocks are inhomogeneous and the intensity of photo...
متن کاملThree-dimensional fracture and fragmentation of artificial kidney stones
The brittle fracture of a gypsum cylinder, which is used as an artificial kidney stone in lithotripsy research, is simulated by the use of the finite element method. The cylinder is submerged in water and is subjected to a pressure front parallel to one of its planar faces. The stresses induced by the pressure wave lead to fracture in the interior of the cylinder, with the formation of a spall ...
متن کاملThe interpretation of granitic textures serial thin sectioning, image analysis three-dimensional reconstruction
Textural development of the felsic phases in two granodioritic rocks from the zoned Linga superunit of the Peruvian Coastal Batholith has been characterized using serial thin sectioning, image analysis and threedimensional reconstruction. The study has shown how each mineral phase contributed to the texture during the formation and development of a contiguous crystal framework and during subseq...
