Recent advances in technology have led to development of low-cost, low-power, and multifunctional sensor nodes capable of sensing, computation and short-range wireless communications. The deployment of large colonies of sensor nodes coordinating among themselves to achieve a more complex sensing task, or simply sensor networks, promises sheer numbers of(More)
Dysfunction of venous valves can lead to hemodynamic disorders causing venous stasis, which would favour the occurrence of equine laminitis. However, very few studies have investigated venous valves in the horse digit. The purpose of this study was to compare valvular density between thoracic and pelvic limbs and to study the relationship between valvular(More)
INTERESTS My main research interest is to develop end-to-end network diagnosis techniques to uncover dynamic network properties (e.g. congestion information, bottleneck equivalence, loss rates, topology, etc.) in a near real-time fashion. This information can be used to characterize the Internet dynamics and to dynamically adapt the control strategies of(More)
The most widely deployed wireless networking (WLAN) standard, 802.11, grants access of the wireless channel to contending stations (STAs) through the Carrier Sense Multiple Access/Collision avoidance (CSMA/CA) mechanism. This approach in general is not scalable, is biased against the network's Access Point (AP), and does not satisfy the Quality-of-Service(More)
This work was designed to investigate (i) the effect of superoxide dismutase (SOD) inhibition on endothelial function and (ii) the free radical-induced endothelial dysfunction in equine digital veins (EDVs) and equine digital arteries (EDAs) isolated from healthy horses. EDV and EDA rings were suspended in a 5 ml organ bath containing Krebs solution. After(More)
