Vehicular ad-hoc networks (VANETs) that enable communication among vehicles have recently attracted significant interest from researchers, due to the range of practical applications they can facilitate, particularly related to road safety. Despite the stringent performance requirements for such applications, the IEEE 802.11p standard still uses the carrier sensing medium access/collision avoidance...
Vehicular ad-hoc networks (VANETs) that enable communication among vehicles and between vehicles and un- manned aerial vehicles (UAVs) and cellular base stations have re- cently attracted significant interest from the research community, due to the wide range of practical applications they can facilitate (e.g. road safety, traffic management, pollution monitoring and rescue missions). Despite this...
Vehicular ad-hoc networks (VANETs) have received a lot of research and industrial attention, including the approval of the IEEE 802.11p standard. However, resource allocation in the standard still makes use of the traditional mechanisms (e.g., carrier sensing) without exploiting the unique characteristics of VANETs. This provides the motivation for this work. As a first step toward the goal and by...
Synthetic aperture radar (SAR) is one of the most promising remote sensor to map forest carbon. The unique spaceborne and long-wavelength SAR data currently available are L-band data, but their relationship with forest biomass is still under controversy, particularly for high biomass values. While many studies assume a complete loss of sensitivity above a saturation point, typically around 100 t.ha...
Topology control for ad-hoc networks is crucial due to the absence of a fixed infrastructure that can guarantee satisfactory connectivity among communication nodes. In this paper, we study the impacts of adjustment of transmission power as a means to control the network topology (connectivity) to the signal-to-interference-plus-noise (SINR) ratio and the number of hops between two nodes, where the...
a) Pre-commercial phase for cables and FCL only b) If available in long length: YBCO better than BSCCO better than MgB2 c) HTS: the only way for applications in the electric power sector d) Cooling costs (capital, running and maintenance costs) ≫ than HTS material costs e) Cost-effective cooling systems, Cryodielectrics for HV and new testing guidelines/codes f) Application research first, but material...
Recent advances in computing technology has brought massively parallel computing power to desktop PCs. As multi-core processor technology becomes mature, a new front in parallel technology based on graphics processors has emerged. A massively parallel 2D-TLM algorithm for NVIDIA advanced graphics processors has been developed. The proposed parallel computing paradigm can be adopted straightforwardly...
The state-space modeling of partially observed dynamic systems generally requires estimates of unknown parameters. From a practical point of view, it is relevant in such filtering contexts to simultaneously estimate the unknown states and parameters. Efficient simulation-based methods using convolution particle filters are proposed. The regularization properties of these filters is well suited, given...
