Outline of Final Research Achievements

The noise which caused by electronic devices degrade the accuracy and uncertainty of the measurements. For example, the fuluctuation of the voltage reference causes error at the process of analog to digital signal conversion.
Therefore it's useful for measurement and control that voltage reference has stabilized and been lower noise. A elastic scattering model that consists from potato starch and grain of rice set on a sieve is proposed. The possibility of the noise reduction would be considered from the angle how a movement of a floury particle changed according to the vibration.
