Application of Machine Learning to Optimize Management of Children in Hospital with Lower Respiratory Tract Infection.

Effective triage can help optimize the use of limited healthcare resources for managing paediatric patients with lower respiratory tract infection (LRTI), the primary cause of death worldwide for under 5 years old children. However, triage decisions do not consider medium to long term needs of hospitalized children. In this study, we aim to leverage data-driven methods using objective measures to predict the type of hospital stay (short or long).

Supervised learning strategy for classification and regression tasks applied to aeronautical structural health monitoring problems.

This paper presents the use of a kernel-based machine learning strategy targeting classification and regression tasks in view of automatic flaw(s) detection, localization and characterization. The studied use-case is a structural health monitoring configuration with an array of piezoelectric sensors integrated on aluminium panels affected by flaws of various positions and dimensions. The measured guided wave signals are post processed with a guided wave imaging algorithm in order to obtain an image representing the health of each specimen.

Guided wave imaging of composite plates using passive acquisitions by fiber Bragg gratings.

In this paper, imaging results of defects in composite plates using guided wave-based algorithms, such as delay and sum and Excitelet, are presented. Those algorithms are applied to passive data for which the signal corresponding to each emitter-receiver couple is recovered as a result of the cross correlation of the ambient noise measured simultaneously by the two sensors. The transition to passive imaging allows the use of lighter sensors that are unable to emit ultrasonic waves, such as fiber Bragg gratings (FBGs) sensors on optical fibers, which are used in this study.

Selective abolition of Mayer waves in conscious endotoxemic rats.

The relation between vascular sympathetic tone and the amplitude of arterial pressure (AP) Mayer waves was examined by analyzing 60-min recordings of AP and renal sympathetic nerve activity (RSNA) obtained in conscious rats before and after lipopolysaccharide administration, which results in strong sympathoexcitation. Mayer waves completely disappeared together with accompanying oscillations of RSNA. Meanwhile, the gain of the sympathetic baroreceptor reflex was increased, thus suggesting that abolition of Mayer waves resulted from the previously reported reduction of vascular reactivity to α-adrenoceptor stimulation.

Passive guided wave tomography for structural health monitoring.

In this paper the authors present a baseline-free quantitative method for imaging corrosion flaws in thin plates. It only requires an embedded guided wave sensor network used in a fully passive way, i.e.
