Single-slit digital radiography: some practical considerations

Off-axis digital hologram reconstruction: some practical considerations.

Holographic rendering of off-axis intensity digital holograms is discussed. A review of some of the main numerical processing methods, based either on the Fourier transform interpretation of the propagation integral or on its linear system counterpart, is reported. Less common methods such as adjustable magnification reconstruction schemes and Fresnelet decomposition are presented and applied t...

Some Considerations on Digital Reading

This paper discusses some changes in the context of reading brought about by new forms of text publishing and reading, such as PDF files, websites and eBooks. In order to do so, the paper starts with some discussion on the importance of such devices. Then explores some of the main their characteristics, as well as some consequences it might bring to the behaviour of readers. It ends with some o...

Lecture : Some Practical Considerations ( 4 of 4 )

Today, we will continue talking about the connection between non-linear dimensionality reduction methods and diffusions and random walks. We will also describe several methods for constructing graphs that are “semi-supervised,” in the sense that that there are labels associated with some of the data points, and we will use these labels in the process of constructing the graph. These will give r...

The Shrinking Generator: Some Practical Considerations

The Shrinking Generator, presented at Crypto'93, is a LFSR-based pseudorandom generator suitable for the implementation of additive stream ciphers. It is particularly simple and has attractive security properties. (The reader is referred to [1] for the definition of the generator and its properties). Although the algorithm was originally intended for hardware implementation, here we will focus ...
