In this work, we present an improved version of an ASIC implementation of the adaptive arithmetic coding algorithm which uses a two-level memory hierarchy. We propose algorithmic modifications and a special hardware structure to speed-up the design without ...

Service robotics, as it has been intended so far, views the accomplishment of a service mission mainly as the result of the action of a single robot. Swarm robotics tackles the very same problem from a different stance, \ie as the result of a team effort ...
In this paper, we present an improved version of microcavity light-emitting diodes, relying on the use of a low-index material, aluminum oxide. Our work addresses in particular the injection scheme required by the insulating nature of this oxide. The devic ...
The cold-neutron triple-axis spectrometer RITA-I at Rise has been operational for about three years, and in the near future an improved version, RITA-2 will replace the existing triple-axis instrument TAS7. We review the performance of RITA-1 and the opera ...
We develop a spline calculus for dealing with fractional derivatives. After a brief review of fractional splines, we present the main formulas for computing the fractional derivatives of the underlying basis functions. In particular, we show that the $ γ ...
In a highly innovative market, wireless systems nowadays undergo very short production cycles. Due to these tough timing constraints, the time-consuming process of prototyping is often neglected, jeopardizing the entire product becoming successful. Heavy a ...

Considerable efforts are presently being made in the fabrication of miniaturized optical devices. An automated assembly technique for small optical components based on standardized holders and on-line alignment of the optical elements has been developed. T ...
Linux offers a rich set of traffic control functions. This document gives an overview of the design of the respective kernel code, describes its structure, and illustrates the addition of new elements by describing a new queuing discipline. ...
Dynamic content Web sites consist of a front-end Web server, an application server and a back-end database. In this paper we introduce distributed versioning, a new method for scaling the back-end database through replication. Distributed versioning provid ...
