Energy flow in light-coupling masks for lensless optical lithography

We illustrate the propagation of light in a new type of coupling mask for lensless optical lithography. Our investigation shows how the different elements comprising such masks contribute to the definition of an optical path that allows the exposure of fea ...

A Contribution to 3D Digital Lines

We propose in this paper a new approach to three-dimensional digital lines (3DDLs) based on the study of the integer lattice generated by the projection of Z3 onto an euclidean plane which reduces the problem to dimension 2. The many properties of this lat ...

Implementing Associations with Ada

Object-oriented programming is a mechanism used to construct modular systems made of reusable components. These systems would be of little use if the objects were all unrelated. This is the reason why the relationships between the objects are one of the ma ...

Heterojunction Band Discontinuities - a Fundamental Problem in Solid-State Science

Giorgio Margaritondo

Heterojunction band lineups have been investigated for over 40 years, and still are one of the most difficult open problems in condensed matter research-with an immediate impact on heterojunction devices. Steady progress has been made at least in understan ...

On the average length of lexicographic paths

Thomas Liebling

A bound is given for the average length of a "lexicographic path", a definition that is motivated by degeneracies encountered when using the randomized simplex method. ...
