A TMA-FDA Approach for Two-Beam Steering
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: Frequency diverse arrays (FDAs) allow the synthesis of dot-shaped radiated patterns in the range-angle space by applying frequency offsets to the antenna elements. Conventional FDAs are usually implemented with ...
Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: The application of frequency offsets to the elements of a conventional phased array with variable phase shifters (VPSs) leads to frequency diverse arrays (FDAs) with the ability to provide range-angle spatial ...
Reply to “Comments on ‘Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns”’
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: It is noted that the main innovation contained lies in the consideration of frequency diverse arrays (FDAs) feeding networks made up of time-modulating switches (hence, the term TMA-FDA) instead of phase shifters. ...
Utilization of a Mobile Application for Motor Skill Evaluation in Children
(MDPI AG, 2021-01-12)
[Abstract]
The detection of needs in educational reinforcement must be done in the early stages of childhood during primary education to improve the acquisition of motor skills. An adequate early intervention can solve ...
Development of dual activities with Micro:Bit for interventions in people with cerebral palsy
(MDPI, 2021-10-12)
[Abstract] Several studies have shown that video games help to motivate users in different kinds of therapies. Therefore, in this work we developed a tool that includes dual activities for therapy, as well as a data system ...
