Temperature-Compensated Clock Skew Adjustment [PDF]

Sensors, 2013
This work analyzes several drift compensation mechanisms in wireless sensor networks (WSN). Temperature is an environmental factor that greatly affects oscillators shipped in every WSN mote. This behavior creates the need of improving drift compensation mechanisms in synchronization protocols.

Balance equations can buffer noisy and sustained environmental perturbations of circadian clocks [PDF]

, 2010
We present a new approach to understanding how regulatory networks such as circadian clocks might evolve robustness to environmental fluctuations. The approach is in terms of new balance equations that we derive.

An Improved Matching Pursuit-Based Temperature and Load Compensation Method for Ultrasonic Guided Wave Signals

IEEE Access, 2020
Temperature and load variations significantly affect ultrasonic guided wave propagation and therefore lead to the increasing of diagnostic uncertainty of the guided wave-based structural health monitoring system, which may cause false reports and false ...

Static temperature analysis and compensation of MEMS gyroscopes

International Journal of Metrology and Quality Engineering, 2013
MEMS gyroscopes as a kind of angular rate sensor have been widely used, but their accuracy tends to be low in practical applications, especially under temperature influence, and they generally require error compensation.
