Optimization of an industrial scale open circuit three-compartment cement grinding ball mill with the aid of simulation
(Elsevier Science Bv, 2016)
An industrial scale FLSmidth (R) three-compartment cement grinding ball mill operating in open circuit was sampled at the steady state conditions. The three-compartment ball mill was modelled by using the perfect mixing ...
Forming Behaviour at Elevated Temperature of a Laser Heat-Treated AZ31 Magnesium Alloy Sheet
(Trans Tech Publications Ltd, 2018)
The tailoring of mechanical and technological properties of the initial material in sheet metal forming has been widely investigated and successfully applied. The benefits of such an approach can be found in the improvement ...
Response of the barrier island coastal region of southwestern Nigeria to climate and non-climate forcing
(Natl Inquiry Services Centre Pty Ltd, 2020)
Despite threats emanating from the influence of climate and non-climate forcing on the barrier island coastal region of southwestern Nigeria, the extent of the coastal erosion is poorly understood. We report evidence of ...
Coastal Erosion Threat on the Kizkumu Spit Geotourism Site (SW Turkey): Natural and Anthropogenic Factors
(Springer Heidelberg, 2020)
The uniqueness of the spits comes from their special coastal geomorphology. Spit's evolution is controlled by the fragile environmental conditions, the sediment input, long shore currents, wave, wind and river processes. ...
Prediction of cementitious grout take for a mine shaft permeation by adaptive neuro-fuzzy inference system and multiple regression
(Elsevier Science Bv, 2017)
Cement grouting is a common technique implemented for permeation and ground improvement in civil and mining engineering projects. Basically, it is the injection of cement and water mixture into a fractured rock mass. Due ...
A Novel Model Predictive Runge-Kutta Neural Network Controller for Nonlinear MIMO Systems
(Springer, 2020)
In this paper, a novel model predictive Runge-Kutta neural network (RK-NN) controller based on Runge-Kutta model is proposed for nonlinear MIMO systems. The proposed adaptive controller structure incorporates system model ...
Relating rock mass properties with Lugeon value using multiple regression and nonlinear tools in an underground mine site
(Springer Heidelberg, 2019)
The Lugeon test is one of the commonly applied field methods for measuring hydraulic conductivity of a rock mass. Understanding hydraulic conductivity is especially necessary when groundwater is present, as it has a direct ...
X-ray CT monitoring of macro void development in mortars exposed to sulfate attack
(Techno-Press, 2018)
This study reports the results of nondestructive monitoring of macro void developments in mortars manufactured with both ordinary Portland cement and sulfate resistant cement. Two types of curing were utilized; tap water ...
Nature of excitons bound to inversion domain boundaries: Origin of the 3.45-eV luminescence lines in spontaneously formed GaN nanowires on Si(111)
(Amer Physical Soc, 2016)
We investigate the 3.45-eV luminescence band of spontaneously formed GaN nanowires on Si(111) by photoluminescence and cathodoluminescence spectroscopy. This band is found to be particularly prominent for samples synthesized ...
A selective approach to index term weighting for robust information retrieval based on the frequency distributions of query terms
(Springer, 2019)
A typical information retrieval (IR) system applies a single retrieval strategy to every information need of users. However, the results of the past IR experiments show that a particular retrieval strategy is in general ...
