摘要： A network management apparatus in a mobile communication network holds a communication quality index in a normal operation and periodically receives input of a communication quality measurement result from a radio base station control apparatus. When a connection failure count f with respect to a connection request count a of each radio cell is obtained as a measurement result, letting p0 be the call loss rate in the normal operation, an upper probability B of a binomial distribution representing the connection failure count becomes larger than f is obtained (step 524). The negative logarithm of the upper probability B is obtained as the score of the degree of abnormality (step 525). Anomaly of communication is detected when the score of the degree of abnormality exceeds a predetermined threshold value (steps 526 and 527). After that, maintenance control is executed in accordance with the calculated score of the degree of abnormality, thereby appropriately avoiding a fault of the communication system. This allows to calculate the degree of abnormality from the measurement result of the communication quality index in the mobile communication network in consideration of the statistical reliability and execute maintenance corresponding to the degree of abnormality.

摘要： Disclosed is a travel-time prediction apparatus that is capable of making a mid-term prediction of travel time accurately by combining present conditions and statistical information. The apparatus includes a travel-time transition pattern database storing travel-time transition patterns obtained by statistically processing past time-series data of each road link according to type of data. Upon accepting a travel-time transition pattern corresponding to a specified link and day type from the database, the apparatus calculates conversion parameters of a travel-time transition pattern for which an error between the travel-time transition pattern and a sequentially input travel-time time-series data will be reduced, and then makes a prediction using a prediction function obtained by converting the travel-time transition pattern by the calculated conversion parameters. The calculated predicted value and the conversion parameters are distributed as traffic information.

摘要： A time series analysis system can perform computation with a less amount of computation than before when a long-term trend component and a long-term cyclic component are handled, or when a plurality of cyclic components is handled. From input time series data including a plurality of cyclic components, long-term time series data of a different series using a plurality of time spans is prepared for each of the time spans. Then, the long-term time series data for each of the time spans is removed from the original time series data, thereby preparing short-term time series data. Then, by learning through probability statistic processing that uses the long-term time series data and the short-term time series data, a model having a time span optimal for prediction of the time series data is selected as an optimal model, and is used for prediction of the time series data.

摘要： The present invention provides the photocatalyst sheet and the methods of welding and manufacturing the same, by which the substrate and resin of the photocatalyst-containing layer are not decomposed by photocatalyst particles, mutual welding of sheets is easy, and the photo-redox effect of a photocatalyst can be obtained. A photocatalyst sheet (1b) comprises a substrate (2) such as fiber and coated layers (3) on both sides of the substrate (2), and the coated layer (3) constitutes the photocatalyst-containing layer in which apatite-coated photocatalyst particles (4) are dispersed and fixed with resin. Here, the coated photocatalyst particles (4) on the surface of the photocatalyst-containing layer are so fixed as to have the parts exposed from the surface of the photocatalyst-containing layer. In case that photocatalyst sheets (1b) are mutually welded, the photocatalyst-containing layer of each photocatalyst sheet (1b) is not removed, and its surface is mutually held, and welded together by thermal welding or others.
