Research in time-series remote sensing data is receiving increasing attention. With the availability of relatively short repeat cycle and high spatial resolution satellite data, the construction and application of high spatiotemporal remote sensing time-series data is promising. In this paper, we proposed a method to construct complete spatial time series data, with Savitzky-Golay filter for sm...

Leddar® optical time-of-flight sensing technology, originally discovered by the National Optics Institute (INO) in Quebec City and developed and commercialized by LeddarTech, is a unique technology in the field of optical sensing. Combining fast, high-resolution analog-to-digital conversion and innovative signal processing, Leddar light processing brings the benefits of timedomain processing to...

In this work, cooperative spectrum sensing technology is applied to optimize the outage probability of cognitive relay networks. The outage performance optimization problem of cognitive relay networks is resolved by designing the sensing time and fusion rule threshold appropriately. The outage probability by high signal to noise ratio (SNR) approximation under Rayleigh fading channels is derive...

The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a ch...

With the development of modern remote sensing technology, a variety of earth observation satellites could continue to tremendously provide image data of different spatial resolution, time resolution, spectral resolution remote sensing, and the remote sensing data obtained is increasing with great capacity, which forms multi-source image pyramid in the same area. To play the advantages of a vari...

we give some new results on sparse signal recovery in the presence of noise, forweighted spaces. traditionally, were used dictionaries that have the norm equal to 1, but, forrandom dictionaries this condition is rarely satised. moreover, we give better estimationsthen the ones given recently by cai, wang and xu.

Multiple secondary users can cooperate to increase the reliability of spectrum sensing in cognitive radio (CR) networks. However, the total transmission power grows approximately linearly with the number of cooperative secondary users. This study proposes a new approach to optimise the trade-off between sensing reliability and power efficiency in cooperative CR networks over fading channels. Th...

Participation of people is the most important factor in providing high quality of service in participatory sensing applications. In this paper we study monetary incentives in order to stimulate user’s participation, especially in applications that rely on real-time data. Providing such incentives is hard because the service provider cannot determine the price at which each user would be willing...

The Institute of Food Technologists has issued this Scientific Status Summary to provide readers with a tutorial on biofilms, their purposeful mechanism of interaction (quorum sensing), and recent findings on how to inhibit their formation.
