We present a method for the separation and resynthesis of drum sources from single channel polyphonic mixtures. The frequency domain technique involves identifying the presence of a drum using a novel percussive feature detection function, after which the short-time magnitude spectrum is estimated and scaled according to an estimated time-amplitude function derived from the percussive measure. ...

Separators are used to protect cathodes from biofouling and to avoid electrode short-circuiting, but they can adversely affect microbial fuel cell (MFC) performance. A spray method was used to apply a polyvinyl alcohol (PVA) separator to the cathode. Power densities were unaffected by the PVA separator (339±29mW/m(2)), compared to a control lacking a separator in a low conductivity solution (1m...

This study is motivated by the development of a blood cell filtration device for removal of malaria-infected, parasitized red blood cells (pRBCs). The blood was modeled as a multi-component fluid using the computational fluid dynamics discrete element method (CFD-DEM), wherein plasma was treated as a Newtonian fluid and the red blood cells (RBCs) were modeled as soft-sphere solid particles whic...

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fi...

This publication presents a method for the automatic detection and classification of three distinct drum instruments in real world musical signals. The regarded instruments are kick, snare and hi-hat as agreed by the participants of the contest category Audio Drum Detection within the 2nd Annual Music Information Retrieval Evaluation eXchange (MIREX 2005). There are two challenging issues inher...

Metal-doped boron clusters provide new opportunities to design nanoclusters with interesting structures and bonding. A cobalt-doped boron cluster, CoB18-, has been observed recently to be planar and can be viewed as a motif for metallo-borophenes, whereas the D9d drum isomer as a motif for metallo-boronanotubes is found to be much higher in energy. Hence, whether larger doped boron drums are po...

PURPOSE Phosphorus (31 P) metabolites are emerging liver disease biomarkers. Of particular interest are phosphomonoester and phosphodiester (PDE) "peaks" that comprise multiple overlapping resonances in 31 P spectra. This study investigates the effect of improved spectral resolution at 7 Tesla (T) on quantifying hepatic metabolites in cirrhosis. METHODS Five volunteers were scanned to determi...

Drum kits consist of various kinds of percussion instruments. As all percussion instruments are large and heavy, they are inconvenient for drummers to carry and set up. Virtual drums, which include motion sensors and enable drummers to imitate playing drums by stroking a virtual drum, are highly portable. However, drummers, who are used to playing real drums, have difficulty in demonstrating th...

Given a plane graph G and two vertices s and t in G, an s-t surface separator is a closed curve C such that s belongs to the other region of R \C than t. A cycle C is called a cyclic surface separator if C is an s-t surface separator, and an odd cyclic surface separator if C is an odd cycle. We consider the problem of finding odd cyclic surface separators in planar graphs and show that the prob...
