Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is ...
We show that network coding allows to realize significant energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus ...
Afin de concevoir et développer un ensemble d’instruments chirurgicaux ultrasoniques permettant de découper ou enlever du tissu humain, du cartilage, des os et surtout, des disques intervertébraux, plusieurs méthodes de transmission et amplification du mou ...
We develop channel estimation techniques for multiple-input multiple-output (MIMO) channels that employ space-time block-coded (STBC) transmissions. We derive the MMSE channel estimator for multi-user Alamouti STBC transmissions over both flat fading and f ...

We compare the system performances of two holographic recording geometries using iron-doped lithium niobate: the 90-degree and transmission geometry. We find that transmission geometry is better because the attainable dynamic range (M/#) is much higher. Th ...
We consider the transmission of variable bit rate (VBR) video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming wit ...
Accumulative indirect evidence of the epidemiology of Mycobacterium ulcerans infections causing chronic skin ulcers (i.e., Buruli ulcer disease) suggests that the development of this pathogen and its transmission to humans are related predominantly to aqua ...
Investigates the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure. Due to the nature of a stress concentration (i.e., the strong nonuniformity of the strain field), the assumption that the ...
An application of the multiple models adaptive control based on switching and tuning to a flexible transmission system is presented. This approach has been considered in order to assure high control performance in the presence of large load variation on th ...
