A heptagonal PCF-based oil sensor to detect fuel adulteration using terahertz spectrum

Sensing and Bio-Sensing Research, 2022
A heptagonal photonic crystal fiber-based oil sensor is proposed and numerically investigated in this paper in order to detect the adulteration of petrol with kerosene using terahertz (THz) signal.

The relative sensitivity of barium swallow examination

Indian Journal of Otolaryngology and Head and Neck Surgery, 2002
In all the cases of P.V Syndrome, it is better to find out by endoscopy even if barium swallow is normal. Thus in P. V. syndrome, the accuracy of barium swallow is only 19% and 81% are reported as false negative.In strictures and malignancies, the level of lesion reported by barium swallow should not be relied upon in all the cases, and they should be ...

On the relative sensitivity of mass-sensitive chemical microsensors

2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011
In this work, the chemical sensitivity of mass-sensitive chemical microsensors with a uniform layer sandwich structure vibrating in their lateral or in-plane flexural modes is investigated. It is experimentally verified that the relative chemical sensitivity of such resonant microsensors is -to a first order- independent of the microstructure's in ...

Proposal for a Quad-Elliptical Photonic Crystal Fiber for Terahertz Wave Guidance and Sensing Chemical Warfare Liquids

Photonics, 2019
A porous-core photonic crystal fiber based on a cyclic olefin homopolymer (Zeonex) is proposed; it shows high birefringence, high core power fraction, low losses, and near-zero flat dispersion. The fiber’s core was designed with quad-elliptical (QE)

Benzene Shape Photonic Crystal Fiber Based Plasma Sensor: Design and Analysis

Photonic Sensors, 2018
A novel benzene core photonic crystal fiber (BC-PCF) is proposed for plasma sensing applications. The proposed BC-PCF parameters have been tuned to gain high sensitivity, high numerical aperture (NA), and low confinement loss, and modality over the ...

A Class of Proximity-Sensitive Measures of Relative Deprivation [PDF]

SSRN Electronic Journal, 2017
We introduce a new class of generalized measures of relative deprivation. The class takes the form of a power mean of order p. A characteristic of the class is that depending on the value of the proximity-sensitive parameter p, the class is capable of accommodating both a decreasing weight (the case of p > 1), and an increasing weight (the case of p

Room temperature sensing of alcohol vapours using novel radially aligned nanorutile titania

Sensors and Actuators Reports, 2023
1D nanostructures of TiO2 have been extensively researched in chemical sensing. The need for deployment of 3D nanostructures such as flower-like and urchin-like morphology for chemical sensing is very essential.

The relative sensitivity to vibration of muscle receptors of the cat [PDF]

The Journal of Physiology, 1967
1. Longitudinal vibration was applied to the de‐efferented soleus muscle of anaesthetized cats while recording the discharge of single afferent fibres from the proprioceptors within the muscle. Conditions were defined under which vibration can be used to excite selectively the primary endings of muscle spindles without exciting the secondary endings of
