Adult worker ants responded the same way to both recordings, such as walking over to the speaker, rubbing their antennae against it, and guarding it.
Radomes not only protect enclosed antennas against wind, rain, ice, snow and solar radiation, but also reduce the manufacturing cost and extend the service time of enclosed antennas [1, 2].
We did not see the rubbing of antennae against the sides of the tank described by Barr and colleagues [20] in any condition.
Finally, the paper compares the distributed antenna system against a MIMO system with co-located antennas based on a 3GPP LTE compliant system-level simulator.
Panel b Positioning of the RF transmission antenna (TX) against the side of the objective lens with TX center point directly below the lens.
Figure 4d shows the GPS distance of the UAV from the radar antenna plotted against time (red line) at a time resolution of 1 s and the corresponding positions of the Capon peaks manually selected from Fig. 4c.
Through the broad windows of the low, nondescript building in which we stood, we could see massive white radio antennas outside against the Martian-red soil of the desolate Chajnantor Plateau, their dishes thrust towards a pure blue sky.
Countermeasures include narrowing the desired channel, thus losing some information but preventing overlap, and using a directional antenna to discriminate against the undesired transmission.
The spokesman, Ilias Kasidiaris, filed lawsuits against Liana Kanelli, a Communist Party candidate, and Rena Dourou, a Syriza party member, accusing them of making unprovoked insults, and against Antenna television for what he claimed was illegal detention.
