Design equations were developedfor two auger configurations that for practical purposes generate uniform vertical flow of granular material through containers or boxes having a rectangular cross-section. Both configurations have uniform outside diameters so the simple geometry of the conventional U-trough housings could be used with these augers. One configuration had a uniform pitch for the au...

Geometric imperfections such as radial imperfection, diamond shape, and local dimples could affect the buckling mode and load carrying capacity of axially compressed steel tubular columns. This paper experimentally investigates the effect of radial imperfection on the load carrying capacity of tubular columns. Test samples include 100 specimens with different values for diameter, length, thickn...

Carbon-coated silicon nanoparticles (40 nm diameter) were used to prepare pitch-based Si/C composites with different Si contents and a pitch graphite-based Si/C/Gr composite. These prepared by pyrolysis at 900 °C of pitch/Si mixture obtained from the dispersion particles in solution THF. The as-prepared delivered high coulombic efficiencies first cycle (83–86%) stable reversible capacities (560...

The evolution of co-rotating streamwise vortices in a canonical flat plate turbulent boundary layer ~thickness of the boundary layer d0.99525 mm) is studied. The vortices are produced by an array of inclined jets ~diameter D514 mm) with the same orientation ~skew angle b and pitch angle a of 45°!. The focus of the investigation is on the immediate vicinity of the jet exit and downstream locatio...

Objective. It is generally accepted that crackles are due to sudden opening of airways and that larger airways produce crackles of lower pitch than smaller airways do. As larger airways are likely to open earlier in inspiration than smaller airways and the reverse is likely to be true in expiration, we studied crackle pitch as a function of crackle timing in inspiration and expiration. Our goal...

Temporal codes and neural temporal processing architectures (neural timing nets) that potentially subserve perception of pitch and rhythm are discussed. We address 1) properties of neural interspike interval representations that may underlie basic aspects of musical tonality (e.g. octave similarities), 2) implementation of pattern-similarity comparisons between interval representations using fe...
