Concrete Undiffused Diffused

This work is motivated by the fact that basestation receiver performance degrades significantly in spatially diffused multipath channels. Herein, this problem is addressed for array DS-CDMA systems in spatially diffused vector channels. Firstly, multipath spatial diffusion is cast as a signal model perturbation problem and then two subspace based receiver techniques are proposed that effectivel...

Predicting the diffusion of information on social networks is a key problem for applications like Opinion Leader Detection, Buzz Detection or Viral Marketing. Many recent diffusion models are direct extensions of the Cascade and Threshold models, initially proposed for epidemiology and social studies. In such models, the diffusion process is based on the dynamics of interactions between neighbo...

A 12-year-old girl presented with a swollen right eye with three days of pain and a diffused swollen frontal region and head lasting for one day. On the computed tomography with contrast, diffused collection was detected in the subgaleal regions and subperiosteal of the right orbita. It was observed that she had bilateral maxillary, ethmoidal, and frontal sinusitis and an infected bilateral mid...

Diffusion of tellurium in undoped p-GaSb has been carried out. Using the cathodoluminescence and photoluminescence techniques, the luminescence centers in Te-diffused samples have been identified and compared with the Te-doped bulk GaSb. Fundamental differences in the radiative levels are observed between the diffused and the as-grown doped samples. Evidence for self-compensating acceptor compl...

VIIRS (Visible Infrared Imaging Radiometer Suite), onboard the Suomi NPP (National Polar-orbiting Partnership) satellite, has an improved resolution of 750 m with respect to the 1000 m of the Moderate Resolution Imaging Spectroradiometer for the channels that allow retrieving cloud microphysical parameters such as cloud drop effective radius (re). VIIRS also has an imager with five channels of ...

Skyrocketing prices of fuel and increasing concerns towards achieving lower carbon footprints favor any improvements a greener transportation ecosystem. In this work we focus on missed approaches, which are forced maneuvers at the end regular flights that generate significant noise pollution levels near airports. previous introduced reinjection technique for maneuver able to substantially mitig...

Multi-Carrier Code Division Multiple Access (MCCDMA) is a modulation scheme that combines the advantages of OFDM and CDMA to provide robustness against frequency selectivity in wireless channels. Arrayed MC-CDMA systems combine MC-CDMA and antenna array technology to harness the spatial and temporal ’signatures’ of received signals, thus making it possible to realize high transmission rates env...
