Methodology for Refinement and Optimization of Dynamic Memory Management for Embedded Systems in Multimedia Applications

David Atienza Alonso

In multimedia applications, run-time memory management support has to allow real-time memory de/allocation, retrieving and processing of data. Thus, its implementation must be designed to combine high speed, low power, large data storage capacity and a hig ...

Storage density of shift-multiplexed holographic memory

Demetri Psaltis

The storage density of shift-multiplexed holographic memory is calculated and compared with experimentally achieved densities by use of photorefractive and write-once materials. We consider holographic selectivity as well as the recording material's dynami ...

Agrandissement du musée suisse de l'agriculture, Burgrain (Alberswil, LU)

Le pret d'agrandissement du musée Suisse de l'agriculture s'inscrit dans le réseau existant et tente de le compléter. La proposition de trois volumes (place de parc, centre de rencontre, et nouveau musée) implantés de manière décalée, est une réponse au pr ...

On Persistent and Reliable Streaming in Ada

Jörg Kienzle

Saving internal program data for further use is one of the most useful ideas in programming. Developing general features to provide such data saving/restoring is a very active research area. There are two application areas for such features we believe to b ...

Method and apparatus for a parallel data storage and processing server

Roger Hersch

The present invention concerns a parallel multiprocessor-multidisk storage server which offers low delays and high throughputs when accessing and processing one-dimensional and multi-dimensional file data such as pixmap images, text, sound or graphics. The ...

Non-volatile hologrphic storage in doubly doped lithium niobate crystals

Demetri Psaltis

Photorefractive materials are being widely investigated for applications in holographic data storage. Inhomogenous illumination of these materials with an optical interference pattern redistributes charge, builds up internal electric fields and so changes ...

Holographic data storage

Demetri Psaltis

Research into and the development of data storage devices is a race to keep up with the continuing demand for more capacity, more density, and faster readout rates. Improvements in conventional memory technologies-magnetic hard disk drives, optical disks, ...

Effect of the sheath resistivity and tape geometry on eddy current loss in Bi(2223) tapes

Bertrand Dutoit

We have made a software electromagnetic simulation of eddy current effects in Bi(2223)Ag sheathed tapes with applied AC transport current in a broad frequency range. We have used simple models of monocore and multicore tapes. Calculated is the power distri ...

SVP: a flexible micropayment scheme

Serge Vaudenay, Jacques Stern

We propose a cheap micropayment scheme based on reasonable requirements. It can be used for any payment which is online between the customer and the vendor and offline with the broker. It is flexible in the sense that many security options are possible, de ...

Performance of a Multiprocessor Multidisk CD-ROM Image Server

Roger Hersch

Professionals in various fields such as medical imaging, biology, and civil engineering require rapid access to huge amounts of image data. Multimedia interfaces further increase the demand for high-performance image and media servers. We consider a parall ...
