This paper analyzes several mitigation strategies and techniques that could enable delay sensitive applications to work properly over satellite IP networks. A study is conducted on different satellite classes (GEO, MEO and LEO) and the analysis of the curr ...
We present the first CMOS-only receiver chip for NMR-applications at 300 MHz. The system consists of an on-chip reception coil, a tuning-capacitor, a downconversion-mixer and a low-frequency gain-stage as well as biasing and offset-compensation circuitry. ...

Dematerialized music and MP3 players offer to the user the possibility of carrying his musical content everywhere. However, at home, the music collection is generally not centralized, split between different rooms and audio supports (CDs, MP3s, etc). In th ...
As with a growing number of athletes, competitive skiers are looking to GNSS technology to help evaluate and improve their performance. Positions logged during practice runs or races can be transformed into 3-D models of the exact trajectories skied to mea ...
The database of satellite images covering the earth is growing extremely quickly and represents an important amount of data. The extension of this huge amount of data with images from very different sources and time of acquisition can provide a wide range ...
This communication presents a review of the developments carried out towards the electromagnetic modeling, design and practical implementation of the basic building block of a planar antenna for the reception of Ku-band satellite broadcasting services from ...
The charge-flipping algorithm in its band-flipping variant is capable of ab initio reconstructions of scattering densities with positive and negative values. It is shown that the method can be applied to reconstructions of difference electron densities of ...
For the universities of the emergent countries, and those of Cameroon in particular, the fight to reach a durable development requires to know the needed scientific and technical information for their development, how to get it and to spread it out among p ...
An artificial transmission line unit cell is presented based on the so-called composite right/left handed transmission line. It is implemented on a microelectromechanical system process on glass, and is suitable for applications such as reconfigurable leak ...
Aperture coupled microstrip patch antennas (ACMPA) are very convenient array elements for designing high directivity planar antennas. Dual polarization ACMPA arrays for Direct Broadcasting Services (DBS) have the problems of low cross-polar discrimination ...
