This paper proposes a new feedback picture sequence control (FPSC) for providing better QOS and more effective usage of network resource in ATM networks. The FPSC utilizes the feedback mechanism of the ABR service and the flexibility of MPEG video coding in order to resolve the collision of I-pictures at switches. The FPSC requires only a very little modification of usage of RM cell in the ABR service. We also describe the MPEG encoder which can change the number of pictures in a GOP. Simulation results show that the FPSC can improve the QOS such as the cell loss ratio and mean buffering delay in the cell buffer of the switch.

This paper presents a new kind of cellular neural network (CNN) called multi-objective cellular neural network (MCNN). Like CNN, it is a large-scale nonlinear analog circuit which processes signals in real time, and it is made of a massive aggregate of regularly spaced circuit clones, called cells, which communicate with each other directly only through their nearest neighbors. Unlike CNN, each cell of MCNN has multiple vectors denoting different cell feature, and one vector will represent the meaning of that cell against other vectors when the network reaches the equilibrium state. Multi-objective cellular neural networks have some characteristics of CNN like: its continuous time feature allows real-time signal processing found wanting in the digital domain, its local interconnection feature makes it ideal for VLSI implementation and its multiple vector characteristic makes it applicable in many fields like image processing.

This paper deals with a problem to coordinate objects according to their impressions. First, the authors propose and define a KANSEI coordination problem, especially the color harmonization and arrangement for color combinations, and then formulate this problem. They simplify the practical complicated problem of arranging and coordinating colors for interior coordinates. This simplification enables one to formulate and finally resolve the problem into an optimization of the evaluation function under some constraint formulas. Therefore, it is expected that many kinds of constraint satisfaction methods can be used. The authors also point out that the evaluation function can be considered as a KANSEI model which can represent the relationship between subjectivity (the degrees of color harmony) and coloring styles.

This paper describes a model-based grasp planner for an articulated multi-fingered robotic hand. The planner searches for an initial grasp from which a required continuous motion of an object is achieved using fingertips alone while keeping rolling contact with the object. An adaptive search strategy has been developed and implemented: the error analysis of the failed grasp is made to find the most promising search direction. A quality measure of manipulation is newly introduced and evaluated to select a better grasp among possible candidates. Simulation results are demonstrated.

A future system for flexible manufacturing must be a sensor-complex for multi-modality with high intelligence, since such a system should work with a human who has a variety of expression methods and acceptance channels. The paper describes three topics from our researches on gesture and haptic interfaces which can be introduced for a human-friendly interface in a designer-consumer cooperative production system. The first one is a gesture information acquisition method using an image processing technique. The second one is another gesture recognition system by employing accelerometers to measure the forces applied to the body. A haptic-communication device is introduced as the third topic of the paper. It is able not only to detect grasping force and the device orientation, but also to display the tactile sensation using the vibration motors to realize human-machine and human-human haptic communications.

This paper proposes a novel phase assignment algorithm "silent wave algorithm (SWA)" for periodic VBR traffic in ATM networks. Our algorithm decides when a new periodic VBR connection should begin to transmit based on its notification parameters and traffic measurement of going connections. Simulation results showed that it is difficult to accommodate pseudo periodic VBR traffic effectively without any phase allocation but the SWA can provide better QOS and improve the network utilization.

We have developed a new parallel processor system specific for the MC analysis, to dramatically reduce the calculation time. Our parallel processor system is based on ring bus architecture. The RISC micro processor chip, which contains a ring bus interface unit (RBIU), a floating point arithmetic unit (FAU) and so on, was also developed for our system. Speed up ratio compared with a single processor reached to 13.5 at 23 PEs.
