    • Many actual data 30, each consisting of a set of an actual water distribution amount obtained in advance from a water management system 10 and a variable needed for prediction, are loaded and retained as history data 52, an input space of a case base 54 is quantized according to a desired output allowance error, each history data 52 is set in the quantized input space, and a case representing at least one history data is prepared to generate a case base 52. Then a similar case corresponding to a newly input prediction condition 40 is retrieved from the case base 54, and a water distribution amount corresponding to the prediction condition 40 is estimated from the retrieved similar case.

    • In a DCFL circuit, a high-speed operation is conducted in a stable state regardless of its load capacitance. The circuit includes a buffer circuit. Added to the buffer circuit is a pull-up circuit conducting a pull-up operation for a predetermined period of time when an output potential of the circuit changes from a low level to a high level. A first EFET of the pull-up circuit includes a gate electrode connected to an output terminal of a logic stage, a drain electrode coupled with a positive power source, and a source electrode linked with a drain of a second EFET. The second EFET includes a gate electrode connected to a node linked in series to a resistor element. The resistor is coupled with an input terminal. The second EFET includes the drain electrode connected to a source electrode of the first EFET and a source electrode linked with an output terminal. Due to the operation of the pull-up circuit for a fixed period of time, the propagation delay time can be minimized without increasing the steady state current when the output potential changes from a low level to a high level.
    • 在DCFL电路中,无论负载电容如何,高速运行均处于稳定状态。 该电路包括缓冲电路。 向缓冲器电路添加的是当电路的输出电位从低电平变化到高电平的预定时间段时进行上拉操作的上拉电路。 上拉电路的第一EFET包括连接到逻辑级的输出端的栅电极,与正电源耦合的漏电极和与第二EFET的漏极连接的源电极。 第二EFET包括连接到与电阻器元件串联连接的节点的栅电极。 电阻器与输入端子耦合。 第二EFET包括连接到第一EFET的源电极的漏电极和与输出端连接的源电极。 由于上拉电路的操作一段固定的时间,传输延迟时间可以最小化,而不会在输出电位从低电平变化到高电平时增加稳态电流。

    • In a state estimating apparatus, an input space quantization section quantizes an input space according to a required precision of output data. A storage section calculates and stores the number of times of occurrence of output data corresponding to each input event in the quantized input space, the mean values of the output data, and the change amounts of the output data. A neighborhood definition section calculates an input space neighborhood satisfying the required precision of the output. A similar case extraction section zooms up the predetermined neighborhood of the input space to the predetermined degree and extracts input case similar to the neighborhood from input case in the input space. A similarity determination section determines the similarity between the new input event and the extracted similar input cases on the basis of the degree of zooming. An estimating section selects input cases corresponding to the similarity from the similar input case, and estimates a value of output data corresponding to the new input event on the basis of the mean value of output data and the mean value of change amounts of the output data.
    • 在状态估计装置中,输入空间量化部根据输出数据的要求精度量化输入空间。 存储部分计算并存储与量化输入空间中的每个输入事件相对应的输出数据的出现次数,输出数据的平均值和输出数据的变化量。 邻域定义部分计算满足输出所需精度的输入空间邻域。 类似的情况提取部分将输入空间的预定邻域放大到预定的程度,并从输入空间中的输入情况提取与邻域相似的输入情况。 相似度确定部分基于缩放程度来确定新输入事件和提取的类似输入情况之间的相似性。 估计部根据类似的输入情况选择与相似度相对应的输入情况,并基于输出数据的平均值和输出数据的变化量的平均值来推定与新输入事件对应的输出数据的值 。
