A simple method has been employed to synthesize Copper and Copper oxide nanoparticles from Copper (II) succinate precursor by thermal decomposition method using oleylamine as a capping agent. The particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from X-ray Diffraction (XRD). The Synthesized copper nanoparticles were characterized by UV-Visib...

Suppose a discrete-time signal ( ), 0 , is a superposition of atoms taken from a combined time–frequency dictionary made of spike sequences 1 = and sinusoids exp 2 ) . Can one recover, from knowledge of alone, the precise collection of atoms going to make up ? Because every discrete-time signal can be represented as a superposition of spikes alone, or as a superposition of sinusoids alone, ther...

The Atomic Decomposition (AD) of an ontology O is a compact representation of all the modules of O. Besides its theoretical value, it has some practical applications, which include optimised reasoning techniques. In this paper we describe the existing programming APIs that allow for the use of the AD of an ontology in Java and C++ programs.

A new four-parameter atomic decomposition of chirplets is developed for compact representation of signals with chirp components. The four-parameter atom is obtained by scaling the Gaussian function, and then applying the fractional Fourier transform (FRFT), timeshift and frequency-shift operators to the scaled Gaussian. The decomposition is realized by extending the matching pursuit algorithm t...
