In this work, an illumination interference reduction technique for visible light communications (VLC) is presented. In this kind of systems an optical wireless communication is established using visible light wavelength, therefore optical filtering for interference rejection can not be employed. Instead of the optical filtering a signal processing based(More)
The adw4 subtype of hepatitis B virus (HBV) belongs to a unique genomic group (genotype F) representing the original HBV strains from the New World. Data regarding the prevalence of this subtype among HBV carriers in South America are, however, scarce, and those concerning HBV genotype F are based on only a few samples from Latin America.

Distance estimation plays an important role in location-based services, which has become very popular in recent years. In this paper, a new short range cricket sensor-based approach is proposed for indoor location applications. This solution uses Time Difference of Arrival (TDoA) between an optical and an ultrasound signal which are transmitted(More)
