In this paper, a concept of individuality and sociality is introduced as a method to avoid conflicts of individual interests in multi-agent systems. It is considered that each agent has its individuality when the conflicts are resolved by making its own mapping from the sensory input to the action output. On the other hand, each agent has sociality when the conflicts are avoided by some common input-output mapping, which is commonly called rules. A conflict avoidance task in which passengers are getting on and off a train are taken as an example, and the emergence processes of both behavioral characters are explained. Furthermore, it is shown that the differentiation of the agent into one of them is adaptively realized by reinforcement learning based on local rewards according to the asymmetry of environment, number of agents, identification of the other agents, or physical ability of agents.

An imaging tactile sensor for the measurement of pressure distributions and a real-time tactile image processing system using the sensor are described.The sensor has a 64×64 array of sensitive sites using pressure-conductive rubber and electrodes on PC board. The scanning circuit of the sensor realizes precise and high speed scanning, 16.7ms per one frame, using a FET at every site for switching. As the output of this sensor is a video signal, pressure distributions can be visualized by a monitor TV and can be recorded by a video tape recorder.By connecting the sensor with a high speed image processor, tactile image processing has been realized. In this paper, showing some examples such as smoothing, contour, trace, and adaptation of tactile images, features of tactile image processing are definitely shown by comparing with visual image processing. This system is used as a developing system of tactile processing algorisms as well as for the measurement of pressure distributions of human body with beds or chairs in the field of human engineering.In this paper, the structure of the sensor and the architacture of the system are described and experimantal results are shown.

Non-restricted estimate of three-dimensional (3D) walk trajectory during indoor locomotion is discussed. The walk trajectory is derived by the integration of the 3D acceleration of subject's foot. A sensor system is composed of an 3D accelerometer, three gyroscops, and one geomagnetic sensor and is attached on the tiptoe. Integral errors of the acceleration and the angular velocity are modified to keep the continuity of the velocity and the posture of the sensor system between the swing phase and the stance phase. Six subjects performed walk experiments including level walk, ascending, and descending in an office building to verify the proposed method. The experimental results show that the estimation error of 3D location to the actual walk distance is less than 10 [%] and the application of the proposed method improves the precise measurement of 3D walk trajectory.

There exist many learning algorithms for finding the synaptic weights of a layered neural network so as to minimize the output errors in response to the plural training data. The most well-known learning algorithms are the backpropagation procedures, in which there are two manners of minimizing the plural error functions in practice. One is minimizing the sum of all error functions totally, and the other is making a reduction of only one error function chosen temporarily and cyclically at each iteration. The former does not always keep the balance and the efficiency in reduction of the plural output errors, and the latter does not guarantee the convergence from the standpoint of numerical analysis.In this paper, we then adopt the learning manner of minimizing the maximum valued function among the all error functions in order to reduce the output errors based on all training data uniformly, and propose a learning algorithm using a non-differentiable optimization method with the generalized gradient in order to guarantee the convergence. An application to the simple recognition problem with plural training patterns and its simulation results show efficiency of our learning manner and algorithm.

The possibilities for the measurements of the blood flow and water contents in the human body by NMR techniques have been analyzed during the last four years. A new technique for this purpose is proposed as one of the new approaches.This paper will deal with the following four topics connected with our past studies for noninvasive testing of biological materials.(1) Proposal of magnetic focusing techniques and generation of the focusing field.(2) Deterioration of the signal level originating frcm the loose coupling between the measuring target and the detector, and minimum limit for measurements of the stationary body fluid utilizing steady NMR.(3) Improvement on the blood flowmeter utilizing pulse NMR.(4) Measurement of the stationary body fluid utilizing pulse NMR.For non-invasive measurements of the nuclear magnetic substances distributed in the human body, a new approach is proposed by utilizing the magnetic focusing technique on the measuring target. And several methods for generating this magnetic focus are discussed theoretically. Moreover, the degree of inevitable deterioration of the signal from the focus induced by a loose coupling between the target in the body and the detector on its surface is calculated theoretically.Theoretical estimations of a new blood flowmeter are shown by taking advantages of the tag effect by radio frequency pulse on the blood flow.For this improvement of the blood flowmeter, the techniques are explained to estimate the pseudo-signal intensity originating from the neighbouring tissues around the blood vessel. A method similar to blood flowmetry can also be applicable to detect the stationary body fluids with some modifications.And some simple assumptions of the minimum limit of detectability are summarized from the view point of bio-medical applications.In conclusion, the authors are able to explain a few considerations and theoretical prospects on these applications of NMR.

Many classes of non-linear systems can be represented by Volterra kernels. In order to obtain the Volterra kernels, one of the authors has proposed a new method by use of M-sequences and correlation function.In this paper, the authors propose a new method for polynomial approximation of non-linear system using the Volterra kernels measured by the M-sequence method. The non-linear system can be approximated as a combination of a linear system and its squared portion. The parameters, which represent the relative magnitude of the squared part, is calculated by use of the Volterra kernels.The proposed method is applied to a non-linear chemical process. From the results of simulations, it is shown that the output signals of the non-linear system calculated by the proposed method agree well with the theoretical outputs.
