Respiratory patterns present great variability, both in healthy subjects and in patients with different diseases and forms of nasal, oral, superficial or deep breathing. The analysis of this variability depends, among others, on the device used to record the signals that describe these patterns. In this study, we propose multivariable regression models to estimate tidal volume (V T ) considering different breathing patterns. Twenty-three healthy volunteers underwent continuous multisensor recordings considering different modes of breathing. Respiratory flow and volume signals were recorded with a pneumotachograph and thoracic and abdominal respiratory inductive plethysmographic bands. Several respiratory parameters were extracted from the volume signals, such as inspiratory and expiratory areas (Area ins , Area exp ), maximum volume relative to the cycle start and end (VT ins , VT exp ), inspiratory and expiratory time (T ins , T exp ), cycle duration (T tot ), and normalized parameters of clinical interest. The parameters with the greatest individual predictive power were combined using multivariable models to estimate V T . Their performance were quantified in terms of determination coefficient (R 2 ), relative error (E R ) and interquartile range (IQR). Using only three parameters, the results obtained for the thoracic band (VT exp , T tot , Area exp ) were better than those obtained from the abdominal band (VT exp , T ins , Area ins ) with R 2 = 0.94 (IQR: 0.07); E R = 6.99 (IQR: 6.12) vs R 2 = 0.91 (IQR: 0.09), E R = 8.70 (IQR: 4.62). Overall performance increased to R 2 = 0.97 (IQR: 0.02) and E R = 4.60 (IQR: 3.68) when parameters from the different bands were combined, further improving when was applied to segments with different inspiration–expiration patterns. In particular, the nose-nose E R = 1.39 (IQR: 0.73), nose-mouth E R = 2.11 (IQR: 1.23) and mouth-mouth E R = 2.29 (IQR: 1.44) patterns showed the best results compared to those obtained for b

Accurate monitoring of respiratory activity can lead to early identification and treatment of possible respiratory failure. However, spontaneous breathing can vary considerably. To quantify this variability, this study aimed at comparing the breathing pattern characteristics obtained from several recording sensors during different breathing types. Respiratory activity was recorded with a pneumotachograph and two inductive plethysmographic bands, thoracic and abdominal, in 23 healthy volunteers (age 21.5±1.2 years, 13 females). The subjects were asked to breathe at their natural rate, in successive stages: first freely, then through their nose, nose and mouth, mouth alone, and finally deep and shallow. Both band signals were compared to the pneumotach-derived (gold standard) volume signal. The time series of inspiratory and expiratory duration, total cycle duration and tidal volume were estimated from each of these signals, and also from the sum of the thoracic and abdominal bands. This composite signal showed the highest correlation with the volume signal for almost all subjects, and also had a significantly higher correlation with those obtained from the gold standard volume, compared to either band. In general, breathing parameters increased from basal to nose-mouth breathing, had a minimum in shallow breathing and a maximum in deep breathing. Women exhibited a significantly longer exhalation phase than men during deep breathing, in the combined bands and the gold standard volume. In conclusion, variations in respiratory cycle morphology in different breathing types can be well captured by the simple addition of abdominal and thoracic band *** Relevance— Breathing pattern variability can be identified by the combination of abdominal and thoracic bands.

Vortex motions are frequently observed on the solar photosphere. These motions may play a key role in the transport of energy and momentum from the lower atmosphere into the upper solar atmosphere, contributing to coronal heating. The lower solar atmosphere also consists of complex networks of ux tubes that expand and merge throughout the chromosphere and upper atmosphere. We perform numerical simulations to investigate the behaviour of vortex driven waves propagating in a pair of such ux tubes in a non-force-free equilibrium with a realistically modelled solar atmosphere. The two ux tubes are independently perturbed at their footpoints by counter-rotating vortex motions. When the ux tubes merge, the vortex motions interact both linearly and nonlinearly. The linear interactions generate many small-scale transient magnetic substructures due to the magnetic stress imposed by the vortex motions. Thus, an initially monolithic tube is separated into a complex multi-threaded tube due to the photospheric vortex motions. The wave interactions also drive a superposition that increases in amplitude until it exceeds the local Mach number and produces shocks that propagate upwards with speeds of approximately 50 km s1. The shocks act as conduits transporting momentum and energy upwards, and heating the local plasma by more than an order of magnitude, with peak temperature approximately 60;000 K. Therefore, we present a new mechanism for the generation of magnetic waveguides from the lower solar atmosphere to the solar corona. This wave guide appears as the result of interacting perturbations in neighbouring ux tubes. Thus, the interactions of photospheric vortex motions is a potentially significant mechanism for energy transfer from the lower to upper solar atmosphere. Copyright © 2018, The Authors.

We present in this paper the general characteristics of a Radio and Plasma Wave experiment that we wish to submit in response to a possible Announcement of Opportunity for the Solar Orbiter payload. This experiment will provide measurements of both electrostatic and electromagnetic fields and waves in a broad frequency band, typically from a fraction of a Hertz up to a few tens of MHz, covering therefore all the scientific objectives described in the Solar Orbiter science requirements document.

Since IEC 61499 has reached the state of an international standard and a substantial body of research results exists the question of the authors as main intention for this paper was: Do the models of IEC 61499 solve all problems when thinking of usability and interoperability in heterogeneous system environments? The main problems discussed within the paper concern to the execution model defined for basic function blocks and the scheduling of events within function block networks.

For patient well-being and also for cost efficiency, constantly improving the medical act is essential. All patients undergo a set of medical tests before going into surgery. In some cases, these tests have to be repeated in different hospitals due to the lack of a system that facilitates presenting and sharing patient's data. We present two e-Health solutions for hospitals and clinics in the medical data field. Our aim was to design and implement a unique system for medical data management. This system allows easy data transfer between medical facilities. It also improves the medical diagnostic and treatment process and it increases the quality of medical care. Also, it improves the communication between patients and physicians, decreases the duration and costs of hospitalization and improves the patient's quality of life. The second medical solution presented in this paper present the results of the medical tests directly to a screen in the operating room, further reducing the time a patient has to wait before going into surgery and also improving the medical act. Both medical solutions were tested in real-world scenarios with promising results.

The goal to control the dynamics of high-rise buildings either to ameliorate the damage or prevent their destruction when subject to an earthquake excitation has been subject of extensive research. All known control designs have advantages and disadvantages as well as operating limits. The application of sliding-mode control to controlling earthquake induced vibrations of a multi-story structural system as an active seismic compensation plus base isolation has been investigated. The performance has been compared to the one of traditional industrial controls, and relevant conclusions drawn. Simulation results, carried out using El Centro earthquake acceleration, have shown that the sliding mode control can decrease significantly displacements of the floors.
