Application of statistical process control for coal particle size
(Taylor and Francis, 2013)
In this article, variations in particle sizes (F50 and P 50) obtained from feeding and ground coals in a vertical roller mill of AS Cement Factory (Turkey) were investigated using control charts and process capability ...
Evaluation of the effects of surface treatments on different dental ceramic structures
(2013)
The surface treatments applied to porcelain materials can be different overglaze methods, chemical interactions and polishing techniques. The aims of these methods are the most durable restoration and the smoothest surface. ...
Rollover crashworthiness analysis of a railroad passenger car
(2013)
Rollover of railroad passenger cars is one of the most serious accidents having high rates of injuries and fatalities. Therefore, the railroad passenger car structures should satisfy the rollover crashworthiness requirements ...
AC chopper application and benefits of auxiliary windings for PSC motors
(2013)
In this work, a novel driver circuit is designed for permanent split capacitor motors (PSC). With this driver circuit, semi-conductive technology is used in place of cumulative winding for this type of motors that are ...
Saturation operation on the direct current motor that is used for manipulator control
(2013)
In this study, the saturation operation on the motor armature current has been carried out with a manipulator control algorithm. Manipulator system is controlled by state feedback plus integral error control strategy. ...
An evaluation of a modified product size distribution model based on t-family curves for three different crushers
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2013)
Crushing is a process which is widely used in mineral processing plants, cement factories, aggregates plants and some other industrial plants. Specific fracture energy of the particles is not the only fundamental property ...
Effects of mill speed on kinetic breakage parameters of four different particulate pumices
(Taylor and Francis, 2013)
In this study, the effect of mill speed was investigated on different particulate pumice samples at batch grinding conditions based on a kinetic model. For this purpose, S i and B i,j equations were determined from the ...
N-O tethered carbenoid cyclopropanation facilitates the synthesis of a functionalized cyclopropyl-fused pyrrolidine
(2013)
We report a facile approach to a cyclopropyl-fused pyrrolidine, which contains four stereogenic centers, by employing the N-O tethered carbenoid methodology. The synthesis was facilitated by the development of a direct ...
Role of NaCl in NaBH4 production and its hydrolysis
(2013)
This study explains completely feasible route to synthesize NaBH 4 by means of mechano-chemical reaction, in which NaCl, B 2O3 and MgH2 were utilized. Optimum reaction conditions were investigated by different values of ...
Integrated definition modeling and Taguchi analysis of flexible manufacturing systems: Aircraft industry application
(2013)
In this paper, flexible manufacturing systems (FMS) are studied. Firstly, an FMS design approach is proposed using integrated definition for function methodology. A systematic layout design and performance evaluation scheme ...
