Calibration and test of DIFAR sonobuoys
2011 IEEE International Symposium on Industrial Electronics, 2011 In this paper, a method for calibrating and testing DIFAR sonobuoy multiplexer without sea or water is proposed. For this purpose; the architecture of DIFAR sonobuoy is introduced, calibration factors are expressed, calibration and test environment in terms of hardware and software are described, calibration and test procedure is explained, and finally,

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

An Improved Calibration Method to Determine the Strain Coefficient for Optical Fibre Sensing Cables
Photonics, 2021 The strain coefficient of an optical fibre sensing cable is a critical parameter for a distributed optical fibre sensing system. The conventional tensile load test method tends to underestimate the strain coefficient of sensing cables due to slippage or ...

Statistical Calibration of Psychometric Tests
, 2004 La psicometria e quella branca della psicologia che si occupa di tradurre in termini numerici le caratteristiche psicologiche della persona o dei suoi comportamenti. Questo approccio ha portato a sviluppare strumenti di misura con l'obiettivo di rendere condivisibili le entita di caratteristiche che altrimenti sarebbero valutabili in un'ottica ...

Antenna Calibration for EMC Tests and Measurements
IEEE Antennas and Propagation Magazine, 2008 An antenna is calibrated in an open-field test site (OFTS) and/or an anechoic chamber, which facilities themselves need calibration. The procedures for calibrated test sites (CALTS) are given in the CISPR and ANSI/IEEE standards. The characteristic parameter for calibrated test sites is the normalized site attenuation (NSA).

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
