Abstract: The present invention applies a particle filter method to the PUCK model for calculating a true market price. First, a probability density function of a parameter is obtained by generating a group of particles having parameters representing the state of the PUCK model each having different values. Then, the degree of conformity of each of the particles is evaluated and the particles are resampled as follows in accordance with the degree of conformity. A random number is compared with a predetermined value, where particles are regenerated in accordance with probability density function such as a normal distribution for making a parameter value of the model at time (t) into a mean value when the random number is greater than the predetermined value, and where the particles are regenerated taking a uniform distribution as the probability density function when the random number is less than the predetermined value.

Abstract: A camber line in a radial section of a runner vane has a curved part extending near the tip of the runner vane is convex toward the front surface of the runner vane. The runner vane is formed in a shape meeting a condition expressed by: ?s<?p, where ?s is the radius of curvature of the back surface of the runner vane and ?p is the radius of curvature of the front surface of the runner vane. The runner vane of this shape suppresses flows toward the tip thereof to moderate the variation of flow velocity in the turning direction. Consequently, loss can be reduced without impeding the recover of pressure in a draft tube.
