One of the most significant issues in any analytical practice is optimization. Optimization and calibration are key factors in quantitation. In matrix-assisted...
Tilt is the slope in waveform values that occurs before and/or after a waveform transition. Tilt causes a bias in the computed values of waveform state levels...
The Energy Conservation in Building and Community Systems program of the International Energy Agency has set up Annex 40, a research working group on...
