Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
(IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
Restoration of the electrocardiogram during mechanical cardiopulmonary resuscitation
(IOP, 2020-04-04)
Objective: An artefact-free electrocardiogram (ECG) is essential during cardiac arrest to decide therapy such as defibrillation. Mechanical cardiopulmonary resuscitation (CPR) devices cause movement artefacts that alter ...
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 ...
Evaluation of chest compression artefact removal based on rhythm assessments made by clinicians
(Elsevier, 2018-01-31)
Aim
To evaluate the performance of a state-of-the-art cardiopulmonary resuscitation (CPR) artefact suppression method by assessing to what extent the filtered electrocardiogram (ECG) can be correctly diagnosed by emergency ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
Solving math and science problems in the real world with a computational mind
(NAER, 2014)
This article presents a new paradigm for the study of Math and
Sciences curriculum during primary and secondary education. A
workshop for Education undergraduates at four different
campuses (n=242) was designed to ...
Computational Thinking in pre-university Blended Learning classrooms
(Elsevier, 2017-05-01)
This article describes the implementation of various core
elements of Computational Thinking in the classrooms of schools of Latin
America and USA in two specific courses: PC-01 and ECE130. These courses
were designed ...
Spanish vs USA cohort comparison of prehospital trauma scores to predict short-term mortality
(Elsevier, 2024-05)
Background
This study aimed to evaluate three prehospital early warning scores (EWSs): RTS, MGAP and MREMS, to predict short-term mortality in acute life-threatening trauma and injury/illness by comparing United States ...
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 ...
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
(Elsevier, 2021-07)
The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ...
