Abstract: A radio communication apparatus includes a plurality of antennas, a radio transmission unit configured to execute radio transmission processing on data to be transmitted from the plurality of antennas, and a processor connected to the radio transmission unit. The processor executes a process including acquiring beam group specification information that specifies a beam group that is capable of being formed when the data to be transmitted is transmitted, forming at least one beam included in the beam group, and correcting an envelope of a beam group using correction factors, the beam group including the at least one beam formed, the correction factors corresponding to the beam group specification information.

Abstract: A system for correctly evaluating a price distribution and a risk distribution for a financial product or its derivatives introduces a probability density function generated with a Boltzmann model at a higher accuracy than the Gaussian distribution for a probability density. The system has an initial value setup unit and an evaluation condition setup unit. Initial values include at least one of price, price change rate, and the price change direction of a financial product. The evaluation conditions include at least time steps and the number of trials. The Boltzmann model analysis unit receives the initial values and the evaluation conditions, and repeats simulations of price fluctuation, based on the Boltzmann model using a Monte Carlo method. A velocity/direction distribution setup unit supplies the probability distributions of the price, price change rate, and the price change direction for the financial product to the Boltzmann model analysis unit.

Abstract: A method embodying this invention for controlling the deceleration of a reversing mill comprises a first step of defining a kickout distance in consideration of the bite speed at which a piece is caught by the main mill roll unit during every return roll pass of a piece-reciprocating operation and the kind of work carried out while the piece is made to rest during an interval between the respective roll passes; a second step of calculating the kickout speed to define the kickout distance; a third step of selecting that one of a plurality of piece position sensors arranged on the bite side of a main mill roll unit which takes the nearest upstream position relative to a mill deceleration-starting point in order to realize the calculated kickout speed; and a fourth step of figuring out a length of time required for the piece to move from the selected piece position sensor to the mill deceleration-starting point, thereby controlling the reversing mill so as to start the deceleration of the piece after lapse of sa
