Analysis of the steps of thermal decomposition of oxo-compounds of the dsp block elements

Analysis of thermal decomposition of manganates(VII) and chromates(VI) in terms of the Górski's morphological classification was used to distinguish typical steps of decomposition of oxides and oxo-salts of dsp block elements and to determine the effect of cationic counterions on decomposition of chromates(VI).

Design of Silicon IP Cores for Biorthogonal Wavelet Transforms

A methodology for rapid silicon design of biorthogonal wavelet transform systems has been developed. This is based on generic, scalable architectures for the forward and inverse wavelet filters. These architectures offer efficient hardware utilisation by combining the linear phase property of biorthogonal filters with decimation and interpolation. The resulting designs have been parameterised in terms of types of wavelet and wordlengths for data and coefficients. Control circuitry is embedded within these cores that allows them to be cascaded for any desired level of decomposition without any interface logic. The time to produce silicon designs for a biorthogonal wavelet system is only the time required to run synthesis and layout tools with no further design effort required. The resulting silicon cores produced are comparable in area and performance to hand-crafted designs. These designs are also portable across a range of foundries and are suitable for FPGA and PLD implementations.
