In this paper we present an initial performance evaluation of the 3GPP UTRA Long Term Evolution (UTRA LTE) uplink with baseline settings. The performance results are obtained from a detailed UTRA LTE uplink link level simulator supporting OFDMA and SC-FDMA schemes. The basic transmission scheme for uplink direction is based on singlecarrier transmission in(More)
Vehicular Ad-hoc Networks (VANETs) have been mainly motivated for safety applications, but non-safety applications can also be very helpful to impulse vehicular networks. Among non-safety applications, video streaming services can provide attractive features to many applications and can attract a great number of users. However, VANETs high mobility(More)
PURPOSE To study the nature and frequency of bacterial contamination during cataract surgery. METHODS The preoperative smears from the conjunctiva and anterior chamber (AC) fluid aspirates during extra-capsular cataract surgery (ECCE) with posterior chamber intraocular lens (PCIOL) implantation in 40 eyes were analysed for aerobic and anaerobic bacteria.(More)
The advent and wide adoption of smartphones in the second half of '00s has completely changed our everyday mobile computing experience. Tens of applications are being introduced every day in the application markets. Given the technology progress and the fact that mobile devices are becoming strong computing devices, mobile <i>applications</i> are expected(More)
Mobile devices are often presented with multiple connectivity options usually making a selection either randomly or based on load/wireless conditions metrics, as is the case of current offloading schemes. In this paper we claim that link-layer connectivity can be associated with informationavailability and in this respect connectivity decisions should be(More)
The vast majority of mobile data transfers today follow the traditional client-server model. Although in the fixed network P2P approaches have been exploited and shown to be very efficient, in the mobile domain there has been limited attempt to leverage on P2P (D2D) for large-scale content distribution (i.e., not DTN-like, point-to-point message transfers).(More)
