Performance Study of Layered Division Multiplexing Based on SDR Platform
(IEEE, 2015-06-05)
[EN] Two of the main drawbacks of the current broadcasting services are, on the one hand, the lack of flexibility to adapt to the new generation systems requirements, and on the other hand, the incapability of taking a ...
RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band
(Wiley, 2019-11-19)
Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were ...
Measurement Methodology for Determining the Optimal Frequency Domain Configuration to Accurately Record WiFi Exposure Levels
(IEEE, 2018-07-04)
[EN] Radiofrequency fields are usually measured in order to be compared with electromagnetic exposure limits defined by international standardization organizations with the aim of preserving the human health. However, in ...
Cardiac output estimation using ballistocardiography: a feasibility study in healthy subjects
(Nature, 2024)
There is no reliable automated non-invasive solution for monitoring circulation and guiding treatment in prehospital emergency medicine. Cardiac output (CO) monitoring might provide a solution, but CO monitors are not ...
Metrics of impulsiveness of manual chest compressions for out-of-hospital cardiopulmonary resuscitation
(Elsevier, 2024-04)
Aim
Propose new metrics of impulsiveness of manual chest compressions (CCs) that account for shape and duration, separate the characteristics of the compressive part of the CC cycle from those of the recoil part, and ...
Yoghurt standardization using real-time NIR prediction of milk fat and protein content
(Elsevier, 2024-04)
A system based on near-infrared (NIR) spectroscopy has been developed for the in-line control of the composition of the milk used as raw material for yoghurt production to control the content of protein and fat in the final ...
