On the relation between underwater acoustic and optical channels. Cruise ALOMEX’15 – Sea Trial.

Speaker: Filippo Campagnaro and Roberto Francescon, Date: 20th of November 2015, Time: 13:30, Room: 201 (DEI/A)

Traditionally, underwater communication employs acoustic modems in order to achieve long transmission range at low bitrate. However, recent studies demonstrate that optical transmissions are most suitable for underwater short range and high bitrate communication. Continue Reading…

Biomedical signal compression with time- and subject-adaptive dictionary for wearable devices

Speaker: Valentina Vadori, Date: 13th of November 2015, Time: 13:30, Room: 201 (DEI/A)

Abstract. Recent advances in wearable devices hold the promise to enhance the efficiency and applicability of telemedicine solutions. These devices allow seamless, non-invasive and inexpensive gathering of biomedical signals such as electrocardiogram (ECG), photoplethysmogram (PPG), heart rate, blood pressure, blood oxygen saturation, and respiration (RESP).

Caching Strategies in Heterogeneous Networks with D2D, small BS and macro BS communications

Speaker: Irene Pappalardo, Date: 6th of November 2015, Time: 13:30, Room: 201 (DEI/A)
Abstract. The increase  in wireless data traffic is encouraging a shift from standard cellular networks, with one base station providing wireless connection to all the users in the cell, to heterogeneous networks, where several small base stations can assist the macro base station in providing connection to all the users.
