Signal and data processing are essential elements in electronic noses as well as in most
chemical sensing instruments. The multivariate responses obtained by chemical sensor …

Desired properties of a chemical sensor include high sensitivity, a large dynamic range, high
selectivity or specificity to a target analyte, related low cross-sensitivity to interferents, perfect …

Abstract The Self-Organizing Map (SOM) algorithm has attracted a great deal of interest
among researches and practitioners in a wide variety of fields. The SOM has been analyzed …

To implement Prognostics Health Management (PHM) for hydraulic pumps, it is very
important to study the faults of hydraulic pumps to ensure the stability and reliability of the …

Gas detection and discrimination have been, until recently, sensors-specific, with different
sensors and techniques used for each of the gases. In this work, we describe a novel …

In recent years, engineered nanostructure assemblies such as nanowire arrays have
attracted much research attention due to their unique chemical and functional characteristics …

The gas sensing behavior of a single SnO2 gas sensor was investigated based on a
dynamic measurement method in which temperature was modulated by heating waveform …

Methane (CH 4) gas sensing properties of novel vanadium dioxide (VO 2) nanostructured
films is reported for the first time. The single phase nanostructures are synthesized by pulsed …

Metal oxide (MOX) has been used as resistive gas sensors for a long time. The gas sensitive
response under constant temperature measurement is a broad-spectrum response, resulting …

We propose a low-voltage (±1V) low-power (3mW) lock-in amplifier, fabricated in a standard
CMOS technology (AMS 0.35 μm) with analog features and utilized for low-frequency gas …
