The design of complex Digital Signal Processing systems implies to minimize architectural cost and to maximize timing performances while taking into account communication and memory accesses constraints for the integration of dedicated hardware accelerator. Unfortunately, the traditional Matlab/ Simulink design flows gather not very flexible hardware blocs. In this paper, we present a methodolo...

The present paper proposes a new algorithm for pitch modification which is convenient for changing the fundamental frequency of speech with so fine resolution that is at least comparable with human pitch perception. Using the proposed method, measurements of just noticeable changes on speech prosody becomes possible. High resolution F0 manipulation is completed without explicit over-sampling of...

Phased logic is a synthesis/mapping methodology that allows a standard clocked netlist (combinational gates + DFFs) to be automatically mapped to a non-clocked netlist that uses special gates called phased logic gates. The new netlist has no clock networks and the only required global signal is a power-on reset. We demonstrate the viability of the phased logic approach via the synthesis and sim...

The synthesis rates of different myosin isoenzymes in a single muscle, and of the same isoenzymes in different muscles (soleus, masseter and plantaris), were measured. The rate of total protein synthesis was significantly higher in the soleus [greater than 95% slow myosin (SM)] than in the plantaris [greater than 95% fast myosin (FM)]. Two fast isoenzymes, FM2 and FM3, were synthesized at diffe...

Myosin light chain synthesis has been analyzed in cultures of fast and slow muscles from chicken and quail embryos. Synthesis was assayed by [35S]methionine incorporation and two-dimensional electrophoresis of total cell extracts. Our results show that differentiated cultures of embryonic anterior latissimus dorsi and pectoral muscles synthesize proteins that comigrate on two-dimensional gels w...

Texture synthesis and morphing are important techniques for efficiently creating realistic textures used in scientific and entertainment applications. In this paper we present a novel fast algorithm for multi-dimensional texture synthesis and morphing that is especially suitable for parallel architectures such as GPUs or direct volume rendering (DVR) hardware. Our proposed solution generalizes ...

Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...

silica sulfuric acid is found to catalyze efficiently the condensation of o-phenylenediamines with various linear and cyclic ketones to afford the corresponding 1,5-benzodiazepines in quantitative yields under solvent-free conditions at room temperature
