Real Time audio conferencing in IP based packet network is one of the popular applications in these days. There are some serious synchronization problems in this technology, some of them are inter stream, intra stream and group synchronization. This paper deals with the problem of audio group synchronization in distributed multiparty group conferencing. When more than one participant in an audi...

In multilingual countries text-to-speech synthesis systems often have to deal with sentences containing inclusions of multiple other languages in form of phrases, words or even parts of words. Such sentences can only be correctly processed using a system that incorporates a mixed-lingual morphological and syntactic analyzer. A prerequisite for such an analyzer is the correct identification of w...

ZnO nanowires with both good crystallinity and oxygen vacancies defects were synthesized by thermal oxidation of Zn substrate pretreated in concentrated sulfuric acid under the air atmosphere, Ar- and air-mixed gas stream. The photoluminescence spectra reveal that only near-band-edge (NBE) emission peak was observed for the sample grown in the air atmosphere; the broad blue-green and the red-sh...

Microclimate variables such as air temperature and relative humidity influence habitat conditions and ecological processes in riparian forests. The increased relative humidity levels within riparian areas are essential for many plant and wildlife species. Information about relative humidity patterns within riparian areas and adjacent uplands are necessary for the prescription of effective buffe...

We consider a finite element method based on biorthogonal or quasi-biorthogonal systems for the biharmonic problem. The method is based on the primal mixed finite element method due to Ciarlet and Raviart for the biharmonic equation. Using different finite element spaces for the stream function and vorticity, this approach leads to a formulation only based on the stream function. We prove optim...

Estimating stream temperatures across broad spatial extents is important for regional conservation of running waters. Although statistical models can be useful in this endeavor, little information exists to aid in the selection of a particular statistical approach. Our objective was to compare the accuracy of ordinary least-squares multiple linear regression, generalized additive modeling, ordi...
