A method and system for data modeling that incorporates the advantages of both traditional response surface methodology (RSM) and neural networks is disclosed. The invention partitions the parameters into a first set of s simple parameters, where observable data are expressible as low order polynomials, and c complex parameters that reflect more complicated variation of the observed data. Variation of the data with the simple parameters is modeled using polynomials; and variation of the data with the complex parameters at each vertex is analyzed using a neural network. Variations with the simple parameters and with the complex parameters are expressed using a first sequence of shape functions and a second sequence of neural network functions. The first and second sequences are multiplicatively combined to form a composite response surface, dependent upon the parameter values, that can be used to identify an accurate model.

A wagering method is provided that allows players or gaming establishments to specify conditions which when satisfied, reconfigure the gaming device to change game play from a first game to a second game.

The second game may be selected from a game on the same gaming device, from a game on a different gaming device, or a game played by a specific player.

A method of automatically controlling a respiration system for proportional assist ventilation with a control device and with a ventilator. An electrical signal is recorded by electromyography with electrodes on the chest in order to obtain a signal uemg(t) representing the breathing activity. The respiratory muscle pressure pmus(t) is determined by calculating it in the control unit from measured values for the airway pressure and the volume flow Flow(t) as well as the patient's lung mechanical parameters. The breathing activity signal uemg(t) is transformed by means of a preset transformation rule into a pressure signal pemg(uemg)(t)) such that the mean deviation of the resulting transformed pressure signal pemg(t) from the respiratory muscle pressure pmus(t) is minimized. The respiratory effort pressure ppat(t) is determined as a weighted mean according to ppat(t)=a·pmus(t)+(1−a)·pemg(t), where a is a parameter selected under the boundary condition 0≦a≦1. The airway pressure paw(t) to be delivered is calculated as a function of preselected degrees of assist VA (Volume Assist) and FA (Flow Assist) by sliding adaptation aspaw(ti)=k0+∑j=1nkj·paw(ti-j)+∑j=0nhj·ppat(ti-j)wherein ti is a current point in time and ti−j, wherein j=1, . . . , n, are previous points in time of a periodical time-discrete sampling, and kj and hj, wherein j=1, . . . , n are parameters dependent on resistance (R), elastance (E), positive end-expiratory pressure (PEEP), intrinsic PEEP (iPEEP), Volume Assist (VA) and Flow Assist (FA) and the sampling time Δt, and the ventilator is set by the control unit so as to provide this airway pressure paw(ti)

In an isolation width depending parameter correcting means 4 of the present invention, an approximate expression of a parameter having an element isolating-purpose insulating film width depending characteristic is formed, and a value of a corrected parameter obtained by employing the formed approximate expression is replaced by a value of an original parameter, so that a transistor model of such a transistor is formed in which element isolating-purpose insulating film widths are different from each other. As a consequence, circuit simulation can be carried out in high precision by considering a change in transistor characteristics caused by a stress, which are approximated to actually measured data.

A method is disclosed for evaluating the physical properties of a sample, for example, the grain size in a polycrystalline material. An ultrasound field is generated in a local region of the sample with a non-contact source, such as a pulsed laser, such that the generated ultrasound diffuses away from said local region. After waiting until the generated ultrasound field has reached a diffusion regime, the resulting ultrasound field is measured with a non-contact detector. Parameters are adjusted in a mathematical model describing the predicted behaviour of the ultrasound field in the diffusion regime to fit the detected ultrasound field to the mathematical model. In this way, parameters dependent on the physical properties of the sample, such as the diffusion coefficient and absorption coefficient, can be derived. The grain size, for example, can be estimated from these parameters preferably by calibrating the diffusion coefficient to grain size.
