With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...

Drum shell bearing edges dictate the boundary conditions and point of contact between drum heads and drum shells. Properties of single 45o, single 45o with slight round-over, and double 45o bearing edges have been studied. It has been found that the double 45o drum allows for the best head/shell energy transfer. I. Background Tom drums are typically composed of a wooden drum shell, a head that ...

In partially wet granular beds, liquid migrates between particles due to collisions and contacts. This, in turn, influences the flow behaviour of bed. We investigate redistribution moving monodisperse a rotating drum using Discrete Element Method (DEM) simulations. For weak capillary forces, re-distribution, induced by continuous particles, leads concentration core bed, where is quasi-static. H...

Wet washing is the most common method for biodiesel purification, but higher water consumption, longer purification time, and high expenses bring limitations on use of this process. One suitable methods to remove such new techniques purification. In study, was evaluated in a novel continuous centrifugal contactor separator (CCCS) at 0.5:1, 1:1, 1.5:1 (V/V%)water ratio; 10 Hz, 20 30 Hz device wo...

We present a live drum separation system for a specific target drumset to be used as a front end in a complete live drum understanding system. Our system decomposes drum note onsets onto spectral drum templates by adapting techniques from non-negative matrix factorization. Multiple templates per drum are computed using a new Gamma mixture model clustering procedure to account for the variety of...

THE Energy Buncher at the low energy beamline of the superconducting fragment separator (Super-FRS) (Figure 1) at FAIR is a valuable and attractive experimental device for particle identification after secondary reactions. This device will be at the heart of the experimental facility for nuclear and reaction (NuSTAR) studies using radioactive ion beams at FAIR. The dipole, quadrupole and sextup...
