Esquisse D'une Synthèse
question of the nature of space and time has occupied scientists and philosophers [1]-[5]. In the four-dimensional space-time of Einstein's wonderful theory of gravity, the squared interval, in units such that the speed of light is unity, is the difference between a squared time increment and the sum of three squares representing the three dimensions of spatial change. More recently higher dime...
متن کاملIntégration de la synthèse mémoire dans l'outil de synthèse d'architecture GAUT Low Power
The systems supporting signal and image applications process large amount of data. That involves an intensive use of the memory which becomes the bottleneck of systems. Memory limits performances and represents a significant proportion of total consumption. In the development high level synthesis tool called GAUT Low Power, we are interested in the synthesis of the memory unit. In this work, we...
متن کاملSimulation Photoréaliste de l'éclairage en Synthèse d'Images
Wavelet radiosity is, by its nature, restricted to parallelograms or triangles. This paper presents an innovative technique enabling wavelet radiosity computations on planar surfaces of arbitrary shape, including concave contours or contours with holes. This technique replaces the need for triangulating such complicated shapes, greatly reducing the complexity of the wavelet radiosity algorithm ...

متن کاملde synthèse commémoratif du centenaire de l ’
When a powerful femtosecond laser pulse propagates in an optical medium, self-focusing occurs. Normally, it is the most powerful part (slice) of the pulse that selffocuses first during its propagation. Self-focusing is balanced by the creation of plasma in the self-focal volume, which defocuses the pulse. This balance leads to a limitation of the peak intensity (intensity clamping). The series ...
