Research ArticleOpen accessEvery word in the titleContribution of Remote Sensing in the Estimation of the Populations Living in Areas with Risk of Gully Erosion in Kinshasa (D.R. Congo). Case of Selembao TownshipKayembe wa Kayembe Matthieu, Ngoy Ndombe Alain, Makanzu Imwangana Fils et al.This paper proposes a methodology combining very high spatial resolution satellite image, GIS and field surveys to estimate the number of people living in areas at (high) risk of landslides or gully erosion in Selembao (Kinshasa). It also gives their socio-economic characteristics. Results show that 185,000 out of the 314,699 inhabitants estimated in Selembao (58.3% of the population) live in … …Current Research in Geoscience, Vol. 6, Issue 1 · 6 Jun 2016 · 8,618 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleBER Performance and Data Throughput of Sinusoidal Template-Based Impulse-Radio Ultra Wideband Receivers for Wireless Body Area NetworksMohamad Abou El-Nasr, Heba ShabanWindowed sinusoidal template-based correlator receivers are good candidates for high-data rate low-power Ultra Wideband (UWB) systems. Their performance approaches the performance of optimal detectors and provides low-power consumption. However, the ultra short pulses of UWB technology makes it sensitive to timing-errors. In this paper, the Bit-Error-Rate (BER) performance and maximum allowable data throughput of Equally-Correlated Pulse Position Modulation (EC-PPM) modulation … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 30 May 2013 · 6,507 accessesView PDFCite
