Allan Deviation Plot as a Tool for Quartz-Enhanced Photoacoustic Sensors Noise Analysis
We report here on the use of the Allan deviation plot to analyze the long-term stability of a quartz-enhanced photoacoustic (QEPAS) gas sensor. The Allan plot provides information about the optimum averaging time for the QEPAS signal and allows the prediction of its ultimate detection limit.

Measurement and instrument noise as proposed in ISO 25178-600 and defined in ISO 25178-700 are assumed to be both stationary and randomly distributed. This paper presents the temporal and lateral Allan deviation as useful tools for deeper noise analysis in surface topography measurements. The temporal Allan deviation may be used to identify and qualify

A flexible device to produce a gas stream with a precisely controlled water vapour mixing ratio and isotope composition based on microdrop dispensing technology [PDF]
Here we describe a versatile device to produce a gas stream with a precisely controlled water vapour mixing ratio and stable water isotope composition based on microdrop dispensing technology. To produce a moist airstream, the microdrop dispensing

Random error identification for MEMS gyro in coal mine underground
Aiming at problems of unrevealing potential error source, hardly separating specific random error and long data collection time of common random error identification methods, Allan variance analysis method was used to identify random error of MEMS gyro ...

Characterization and Benchmark of a Novel Capacitive and Fluidic Inclination Sensor
In this paper, a fluidic capacitive inclination sensor is presented and compared to three types of silicon-based microelectromechanical system (MEMS) accelerometers. MEMS accelerometers are commonly used for tilt measurement.

Evaluation of the ultimate performances of a Ca+ single-ion frequency standard [PDF]
We numerically evaluate the expected performances of an optical frequency standard at 729 nm based on a single calcium ion. The frequency stability is studied through the Allan deviation and its dependence on the excitation method (single Rabi pulse or ...

Extending Non-Ambiguity Range of Dual-Comb Ranging for a Mobile Target Based on FPGA
Dual-comb ranging (DCR) is an important method in absolute distance ranging because of its high precision, fast acquisition rate, and large measuring range. DCR needs to obtain precise results during distance measurements for a mobile target.

Allan variances and its related methods are commonly used to analyse a sequence of data in the time domain to measure frequency stability of oscillators. It allows for a determination of noise type as a function of the averaging time.

About the stochastic features during intracranial pressure transients – the Allan deviation
Objective: The Allan deviation (AD) has not been generally used as a tool to determine the statistical properties of intracranial pressure (ICP) up to now. This fact is remarkable because concordance to modern analytic methods applied to ICP (i.e., the wavelet variance) exists. AD becomes important [for full text, please go to the a.m. URL]

Micro and nano electromechanical resonators have been widely used as single or multiple-mass detection sensors. Smaller devices with higher resonance frequencies and lower masses offer higher mass responsivities but suffer from lower frequency stability.
