This paper presents a novel drone system used for in-situ measurement of carbon dioxide (CO2), which is one of greenhouse gases. To obtain a vertical profile of atmospheric CO2 concentration, a Non-Dispersive Infrared (NDIR) analyzer was equipped on an off-the-shelf industrial drone. We designed and assembled an original mount which consists of carbon plates, hollow aluminum pipes, and resinous adapters created using a 3D printer. We obtained vertical CO2 profiles up to the 500m level through a flight test of five different dates after getting the flight permissions at an altitude of more than 150m above the ground and Beyond Visual Line of Sight (BVLOS) from the Ministry of Land, Infrastructure and Transport. It is shown that CO2 concentration generally increases with altitude, though the feature of CO2 profiles varies with observation dates. Based on the five profiles from September 2017 to January 2018, we revealed a seasonality of CO2 concentration over Akita. We suggest that this system is useful for in-situ CO2 measurement and enables to conduct frequent and easy observations.

In this paper, we propose a filter to satisfy velocity and acceleration limits for arbitrary input signals. The shapes of input signals are sometimes converted into trapezoidal wave in order to prevent an overload on the robot in FA field. Generally, physical protection of equipments, safety and ride quality are achieved with limitations for input signals about some properties. For achieving such limitation, the filters which limit some signal properties are widely used. A filter structure to satisfy velocity and acceleration limits was designed only simple feedback control with the saturation function. However, this structure had a problem that time-lag between the input signal and modified signal is occurred. To solve this problem, we propose a filter structure which is based on the model error compensator. Modified signal which is generated by the proposed filter satisfies the desired signal constraints for any input signals. By the proposed structure, time-lag can be smaller than the signals obtained by the previous method. The effectiveness of the proposed filter is shown by the numerical examples.

The appearance of the symptoms of excess cancer incidence and non-carcinogenic by pollutant is found in many people by a wide variety of degree. This reason is the difference of per day of pollutant exposure to risk indicators and sensitivity by age and sex. In particular, infants and school children in a growth phase, is called “the environment weakness”. In this study, we analysis exposure assessment representing the individual's lifestyle with different life action in every generation. Among them, we construct “lifestyle exposure model”. And this study focus Benzene and PM2.5 in specific area. Then we are explicit about exposure by breathing in generation and lifestyle.
