Perte, acquisition, transformations

Simultaneous acquisition of multiple auditory-motor transformations in speech.

The brain easily generates the movement that is needed in a given situation. Yet surprisingly, the results of experimental studies suggest that it is difficult to acquire more than one skill at a time. To do so, it has generally been necessary to link the required movement to arbitrary cues. In the present study, we show that speech motor learning provides an informative model for the acquisiti...

Lossless and nearly-lossless image compression based on combinatorial transforms. (Compression d'images sans perte ou quasi sans perte basée sur des transformées combinatoires)

Common image compression standards are usually based on frequency transform such as Discrete Cosine Transform or Wavelets. We present a different approach for lossless image compression, it is based on combinatorial transform. The main transform is Burrows Wheeler Transform (BWT) which tends to reorder symbols according to their following context. It becomes a promising compression approach bas...

On p-semilinear transformations

In this paper, we introduce $p$-semilinear transformations for linear algebras over a field ${bf F}$ of positive characteristic $p$, discuss initially the elementary properties of $p$-semilinear transformations, make use of it to give some characterizations of linear algebras over a field ${bf F}$ of positive characteristic $p$. Moreover, we find a one-to-one correspondence between $p$-semiline...

Transformations Debugging Transformations

Practical model transformation (MT) frameworks are usually composed of multiple execution contexts, building an overall workflow by abstracting different aspects of execution. This heterogeneity brings additional challenges to debugging, which must address a combination of quite different graphical and textual formalisms. In this work we describe a layered approach to debugging, mapping familia...
