We study signal processing tasks in which the is mapped via some generalized time-frequency transform to a higher dimensional space, processed there, and synthesized an output signal. show how approximate such methods using quasi-Monte Carlo (QMC) approach. consider cases where representation redundant, having feature axes addition time frequency axes. The proposed QMC method allows sampling bo...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

Biodiesel is an attractive renewable energy source, which is suitable as a substitute to the non-renewable petroleum diesel. However, it is plagued by its relatively bad cold flow behaviour. In this review, the factors affecting the cold flow of biodiesel, vis-à-vis the contradicting requirement of good cold flow and good ignition properties, are discussed. Fuel filter plugging, and crystalliza...

Concatenative synthesis is currently the favoured approach to text-to-speech synthesis, yet it has fundamental limitations. In the longer-term, articulatory synthesis has much greater potential. Different approaches to articulatory synthesis are discussed in terms of the choices made concerning the articulatory processes modelled, the simplifying assumptions, and the data collected.

nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. importance of the magnetic nanomaterials in biomedical science cannot be overlooked. the most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. however monodispersion, selection of an appropriate coati...

We describe the attempt to synthesize emotional speech with a concatenative speech synthesizer using a parameter space covering not only f0, duration and amplitude, but also voice quality parameters, spectral energy distribution, harmonics-to-noise ratio, and articulatory precision. The application of these extended parameter set offers the possibility to combine the high segmental quality of c...

A simple quantitative approach to enable chemists to compare alternative chemical syntheses on the lab bench with respect to their resource usage and their potential environmental impact is proposed; this may be useful for the systematic design of more sustainable processes. We consider as metrics the mass index S(-1) and the environmental factor E to characterize quantitatively the reaction in...
