Accurate modeling of co-articulation, the context-sensitive merging of the boundaries between allo-phones in continuous speech, is vital for natural sounding speech synthesis. This paper describes initial research investigating the use of Bézier Curves to form models of co-articulation in human speech. A 12th order, pitch synchronous line spectral pair(More)
Regardless of its lethal effects upon Escherichia coli (E. coli) cultures trough the production of free radicals (FR), stannous chloride (SnCl2) remains to be the most used reducing agent on the production of technetium-99m radiopharmaceuticals, to obtain images on nuclear medicine. Moreover, authors have reported that vegetal extracts are able to protect(More)
One of the primary motivations of BPMN is to provide an easy to understand standard way to define and visualize business process models. This goal is addressed with respect to the control flow perspective. However, the support it provides to the resource perspective is poor. This work presents an extension to the BPMN 2.0 metamodel and notation to support(More)
Since ancient times propolis has been employed for many human purposes because to their favourable properties. Blood constituents labeled with technetium-99m (99mTc) have been used in nuclear medicine procedures. Some authors have reported that synthetic or natural drugs can interfere with the labeling of blood constituents with 99mTc. The aim of this work(More)
