This paper investigates emotion recognition from breath gas information. A breath gas sensing system is designed by using a quartz crystal resonator with a plasma-polymer film as a sensor. For computational experiment of emotion recognition, the machine learning-based approach, such as artificial neural network and support vector machine, is investigated.(More)
This paper proposes a smart gas sensing system to achieve emotion recognition using breath gas information. A breath gas sensing system is designed by using a quartz crystal resonator with a plasma-polymer film as a sensor. To collect breath gas data under emotional state, psychological experiments are carried out using a dental rise to excite emotions. In(More)
Parametric relationships between the genotype x environment interaction and the genetic correlation of the same attribute measured in two different environments are derived. It is shown that the criticism by Fernando et al. (1984) of Yamada's method (1962) in the case of unbalanced data is irrelevant.
Thin layers of pyroglutamic acid (Pygl) have been deposited by thermal evaporation of the molten L-glutamic acid (L-Glu) through intramolecular lactamization. This deposition was carried out with the versatile handmade low-vacuum coater, which was simply composed of a soldering iron placed in a vacuum degassing resin chamber evacuated by an oil-free(More)
This paper proposes a mathematical model of a mass-sensitive chemical sensor with a PPF-coated quartz crystal resonator (QCR) to enable its use for the signal processing of gas sensing systems that are operated under ambient conditions. To approximate the pulse-like responses of the PPF-coated QCR sensor to the sample gas and adsorbed water, a mathematical(More)
This study investigates a method for recognition of tea aroma using a multilayer neural network. A gas-sensing system utilising an array of quartz crystal resonators coated with plasma-organic-polymer-films is designed. Three teas, oolong, jasmine and puerh, are used as the sources of sample gas. Wavelet transform frequency analysis is applied to the(More)
