The authors present an approximate analysis of an asymmetric token ring network with nonpreemptive priority under a new discipline named the go-back-to-higher-priority discipline. This discipline is described and the token ring network is analysed on the basis of the independent hypothesis for the distribution of the cycle time. Then, probabilities for the number of messages at the token's arrival, a mean cycle time, a mean intervisit time of the token and a mean waiting time of messages for each priority level are obtained. To calculate the mean waiting time for a lower priority level, a root of the denominator of the generating function plays an important role. In some numerical examples with simulation results, the mean waiting time for the go-back-to-higher-priority discipline is compared with that for an asymmetric token ring network with nonpreemptive priority under a one-limited discipline.< >

A simple approach is presented for simultaneous on-line identification of the time delay and the system parameters of continuous-time systems based on discrete-time measurements. The linear integral filter is used both to construct the derivatives of input-output signals and to avoid estimating the unknown initial conditions. The time delay and the system parameters are directly estimated by an on-line algorithm which is derived using Newton’s method. Severed identification methods such as the bias-compensating method and the instrumental variable methods are applied for eliminating the asymptotic bias of the parameter estimates in noisy situations. The present algorithm is applicable to the case when the time delay is not an integral multiple of the sampling interval, and can also be used for model reduction.

The technique of adaptive linear filtering is improved. An adaptive filtering procedure that could be used in the application of the neural network techniques is considered and a control system which adjusts parameters of the adaptive filter by means of a multilayered neural network is designed. The neural network can be trained to adaptively produce the parameters by minimizing the error between the desired output and the output signal of the adaptive filter. After training, the neural network's weights are fixed. Experimental results confirm that the proposed technique has significant effects on the smoothing problem.< >

An advanced mathematical model of a shape memory alloy (SMA) useful for designing SMA micro-devices is proposed and applied to coil spring theory to analyze the appropriate mechanical and electrical characteristics. This model can handle three phases of the SMA: the parent phase, the martensitic phase, and the R-phase. of three steps. First, the mechanical properties of the three phases are modeled at the solid mechanics level. Second, a model of thermoelectric transformation is obtained at the thermodynamic level. Finally, the first and second steps are combined. The model was applied to coil spring theory and was verified successfully by experiments under general conditions.< >
