Wavelets are used in the analysis of sounds and images, as well as in many other applications. The wavelet transform provides a mathematical analog to a music score: just as the score tells a musician which notes to play when, the wavelet analysis of a sound takes things apart into elementary units with a well defined frequency (which note?) and...

Discussing current trends in silicon technology influencing image sensor design - stacking silicon is a way to mitigate moving technology to a next silicon node while maintaining the trend of density increase in integrated circuits. Several examples of stacked image sensors will be discussed. Stacking image sensors with computational elements ca...

Seifert fibered spaces are 3-dimensional manifolds with a 2-dimensional quotient space. Surfaces in Seifert fibered spaces fall into two categories: Compressible and incompressible. The structure of Seifert fibered spaces allows for a complete description of essential surfaces in Seifert fibered spaces in terms of a simplicial complex derived fr...

Surfaces appear naturally in low dimensional topology and its applications. They can be described in several different ways, each with advantages and disadvantages. A complete classification can be given. Several structures, including geometric structures and curve complexes provide information on surfaces and higher dimensional manifolds.

We present a strategy for the simulation of nonadiabatic excited statedynamics by surface hopping, with direct calculation of the electronicwavefunctions and energies. The electronic problem is solved by asemiempirical NDO method, especially modified to deal with excitedstates, bond breaking and orbital degeneracies. A reparameterization ofthe s...
