High-Frequency Ventilation [PDF]
Anaesthesia and Intensive Care, 1986 Over the last six years high-frequency ventilation has been extensively evaluated both in the clinical and laboratory settings. It is now no longer the great mystery it once was, and it is now no longer believed (as many had hoped), that it will solve all the problems associated with mechanical pulmonary ventilation.

Non-Invasive Determination of the Mass Flow Rate for Particulate Solids Using Microwaves
Sensors, 2023 This paper presents a novel technique for the mass flow rate determination of particulate solids called the “Sliding Mass Technique”. The mass flow rate is a measure of the mass of a substance that passes through a given cross-sectional area per unit ...

A Wide Frequency Scanning Printed Bruce Array Antenna with Bowtie and Semi-Circular Elements
Sensors, 2020 A printed edge-fed counterpart of the wire Bruce array antenna, for frequency scanning applications, is presented in this paper. The unit-cell of the proposed antenna consists of bowtie and semi-circular elements to achieve wide bandwidth from below 22 ...

SSRN Electronic Journal, 2019 This paper studies the behaviour of Bitcoin returns at different sample frequencies. We consider high frequency returns starting from tick-by-tick price changes traded at the Bitstamp and Coinbase exchanges. We find evidence of a smooth intra-daily seasonality pattern, and an abnormal trade- and volatility intensity at Thursdays and Fridays. We find no

Current Opinion in Anaesthesiology, 1988 The need to maintain adequate gas exchange in patients with respiratory insufficiency led already in the early beginning of the 20th century to the development of certain methods which can be apostrophized as the basis of the today techniques of the so called “High Frequency Ventilation” (HFV).

Seeding-Layer-Free Deposition of High-k Dielectric on CVD Graphene for Enhanced Gate Control Ability
Crystals, 2022 The gate insulator is one of the most crucial factors determining the performance of a graphene field effect transistor (GFET). Good electrostatic control of the conduction channel by gate voltage requires thin gate oxides.

Comparison of non-convex cost functionals for the consideration of phase differences in phaseless near-field far-field transformations of measured antenna fields [PDF]
Advances in Radio Science, 2017 This work introduces two methods which extend the non-convex minimization problem arising in phaseless (NF) far-field (FF) transformations. With the new extensions, knowledge about phase differences between measurement points can be incorporated into ...
