To compare energy expenditure during and after active and handheld video game drumming compared to walking and sitting. Ten experienced, college-aged men performed four protocols (one per week): no-exercise seated control (CTRL), virtual drumming on a handheld gaming device (HANDHELD), active drumming on drum pads (DRUM), and walking on a treadmill at ~30% of VO2max (WALK). Protocols were perfo...

The motion of binary particles in three horizontal rotating drums with continuous rotational speed changes was studied based on the Discrete Element Method (DEM). Different simulation conditions were compared between two circular and an elliptical drum using same number physical properties for drums, at a series from 0.01 to 21.9 rad/s. By varying speed, four flow regimes produced simulation. F...

The mixing of granular materials in an agitated drum can be characterized by the dimensionless power equation. equation was created dimensional analysis, for which parameters affecting requirement were collected based on literature. most important these are rotational speed, loading factor, geometric and physical properties materials. is used to estimate with reasonable accuracy Power number wi...

Aiming to solve the problem that internal resistance of dynamometer is regarded as a constant force by traditional test method, which causes measurement precision vehicle driving wheel instantaneous output power be insufficient, system for drum movement was constructed, method put forward, and mathematical model established. Model analysis experimental results showed actual reflected more accur...

This paper investigates the mechanical properties of oriented polyvinyl chloride (PVC) nanofiber mats, which, were obtained by electrospinning a PVC solution. was dissolved in solvent mixture tetrahydrofuran/dimethylformamide. Electrospinning parameters used our work were, voltage 20 kV; flow rate 0.5 mL/h; distance between syringe tip and collector 15 cm. The rotating speed drum varied from 50...

Two exposure sessions consisted of 5 minutes in the optokinetic drum rotating clockwise at 35 degrees per second (slightly greater than the 5 r.p.m. used in previous experiments). Subjects viewed the drum with their spectacles or contact lenses on for one session, followed by a 20 minute rest period, then viewed the same optokinetic stimulation without their spectacles or contact lenses. Six su...
