Research ArticleOpen accessIn the abstractA NOVEL SPEECH ENHANCEMENT APPROACH BASED ON MODIFIED DCT AND IMPROVED PITCH SYNCHRONOUS ANALYSISV. R. Balaji, S. SubramanianSpeech enhancement has become an essential issue within the field of speech and signal processing, because of the necessity to enhance the performance of voice communication systems in noisy environment. There has been a number of research works being carried out in speech processing but still there is always room for improvement. The main aim is to enhance the apparent … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 21 Nov 2013 · 6,796 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Plant Species Suitability for a Substrate-Free Tropical Green RoofBruno R. Silva, André Mantovani, Dulce G. Mantuano et al.Greenroofs reduce building exterior-interior thermal flux and mitigate high internal air temperatures, especially in tropical climates. Tropical greenroofs are given little attention and their use remains restricted to a very low percentage of roofs due to high costs compared to traditional roofs, weight overload (mainly due to the chosen substrate) and potential waterproofing problems. We here present an alternative greenroof … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 11 Oct 2018 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of Organelle Genomes of Extra Nuclear Sunflower Mutants with Variegated PhenotypeIrina Dremuk, Nikolay Kozel, Mariya Logacheva et al.The comparative analysis of complete chloroplast and mitochondrial DNA sequences of the original inbred line 3629 and three extra nuclear mutant lines variegated-1, variegated-15, variegated-17, obtained by the N-nitroso-N-methylurea induced mutagenesis, was done. The studied mutant lines were presented two different phenotypes with diverse chlorophyll content: Pale/green mutant line variegated-17 with 1.8% relative (to 3629 line) chlorophyll content in mutant … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,633 accessesView PDFCite
