Smartphone indoor positioning based on enhanced BLE beacon multi-lateration
In this paper, we introduce a smartphone indoor positioning method using bluetooth
low energy (BLE) beacon multilateration. At first, based on signal strength analysis,
we construct a distance calculation model for BLE beacons. Then, with the aims…

Performance of multi-hop cognitive MIMO relaying networks
with joint constraint of intercept probability and limited interference
In this paper, we propose a multi-hop multiple input multiple output (MIMO)
decode-and-forward relaying protocol in cognitive radio networks. In this
protocol, a multi-antenna secondary source attempts to send its data to a multi-
antenna…

Lower and upper bound form for outage probability analysis in two-way of half-duplex relaying network under impact of direct link
In this paper, the system performance of the two-way of half-duplex (HD)
relaying network under the impact of the direct link is studied. The model
system has two sources (S) and one destination (D) communicate by direct link
and via relay (R).…

Coronal slice segmentation using a watershed method for early identification of people with Alzheimer's
One physical sign of a person who has Alzheimer's is the diminution of the
area of the hippocampus and ventricles. A good quality magnetic resonance
imaging (MRI) will provide a high-quality image so that the doctor will
quickly analyze the…
