There must be no chemical reaction between the sensor material and the sample. Use a sensor with a low cell constant (0.01 to 0.1 cm-1) for low conductivity measurements and a sensor with a higher ...

The electrocardiogram (ECG) signals P-wave, QRS wave and T-wave all reflect the activity of the heart, and the analysis of ECG signals can provide basic information for the diagnosis and prevention of ...

The problem of choosing the best subset of sensors that guarantees a certain estimation performance is referred to as sensor selection. In this paper, we focus on observations that are related to a ...
