Abstract(in English) | Five years have passed since the Fukushima nuclear power plant accident, and the decontamination project in disaster areas led by related ministries and agencies achieved certain results mainly in the residential area. Meanwhile, in radiation measurement after decontamination in nuclear disaster areas affected by nuclear power plants, it is known that the local high dose sites called hot spots are scattered. The measurement method of efficient and simple and also different from conventional method is required in order to search for local hot spot factors. In study, this paper proposes the method of using inference model possessed nonlinearity as the way to minimize the influence of both mechanical and stochastic noise included in the sensors and data regarding time-series data monitored by using external sensors. Furthermore, we apply this method to data monitored while moving at a constant speed in order to realize more efficient radiation measurement this time. There are many methods including the Newton method for numerical analysis in nonlinear characteristics, which are generally represented as multidimensional nonlinear function models. And also determining the specified model from the time series data is to determine the parameters of its model. In this paper, we presume the parameters of the model with repeating the least squares method computation steps multiple times on the n-number of transition from the starting point of searching in time series data based on a function model. |
