Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency comparison with conventional tumbling mills. In this context, agitator liner wear plays an important role maintenance planning and operational costs. paper, we use discrete element method (DEM) simulation evaluate screw wear. Three different mill rotational velocities are evaluated simulation...

conceptualization The observations and reflections were distilled into 'abstract concepts' that produced plans for action which could be 'actively experimented' with during the second night Knowledge Management and IT 605 of study. Plans at the operational, project, organizational and research levels were distinguished: Operational level (asphalt team)  The asphalt temperature throughout the w...

BACKGROUND Nordic combined (NC) is an Olympic winter-sport performed as a ski jumping (SJ) event followed by a cross-country (XC) pursuit race employing the skating style. PURPOSE To elucidate the associations between sport-specific laboratory capacities and SJ, XC skiing, and overall NC performance in a world-cup NC event. METHODS Twelve international world-cup NC athletes from 8 nations p...

1 I n t r o d u c t i o n In food industry, we can find many manipulative operations that deal with deformable rheologic materials such as dough, paste, jelly, and meat. Most these operations are done by humans. Especially, operations with large deformation of rheologic objects depend upon humans. For example, forming of pizza dough to a thin circular shape is performed by humans while extensio...

This paper describes the ROLLENT system submitted to the Eight International Planning Competition, Learning Track. ROLLENT combines two machine learning techniques: generation of entanglements and decision tree learning by ROLLER. Entanglements capture causal relationships for a class of problems while ROLLER learns relational decision trees useful to sort the applicable operators at a given st...

This paper is concerned with optimization of process parameters for a roller leveller that is an indispensable equipment to eliminate the undesirable curvature of a thin-walled aluminum pipe. Optimization of process parameters has been carried out for a multistaggered-type 14-roller leveller. A finite element model of a multi-staggered 14-roller leveller was constructed for analysis whose resul...

[Purpose] This study aims to examined the effect of the self-myofascial release induced with a foam roller on the reduction of stress by measuring the serum concentration of cortisol. [Subjects and Methods] The subjects of this study were healthy females in their 20s. They were divided into the experimental and control groups. Both groups, each consisting of 12 subjects, were directed to walk f...

This paper concerns the tension control of roll-to-roll systems. In such systems, each driven roller speed is controlled separatly. The impact of the master roller position on tension control performances is studied using optimized web tension control synthesis. The tension disturbance rejection property and the system robustness regarding web elasticity variations are analysed for each configu...
