In this talk, we present results on nonlinear system identification of the inpedance matching system for the plasma chamber in the semi-conductor production.We apply the mimimum norm method (which is abbreviated as MN) that is appropriate for identification of the system described by the series of linear dynamical and nonlinear static parts.

This paper reports a Java-based operation support system integrated with a "Large scale database Online Modeling (LOM)" and a blast furnace simulator. The system predicts blast furnace operation by combining the partial unsteady simulator of the physical modeling method and LOM of the local modeling method and supports the operation. To construct the system, the Java-based partial unsteady blast furnace simulator is developed.

In this paper, a driver model which can evaluate performance of obstacle avoidance algorithm is developed. The driving data is collected by a small-scale traffic stream simulator using CarSim. Hybrid modeling is applied to construct the drive model. It is shown that the developed driver model can simulate driver's avoidance behavior through numerical simulations.

A power assist system for an omni-directional wheelchair is developed considering operability. Operability is improved by using fuzzy rules that must be tuned in order to respond to each attendant's characteristics. A neuro-fuzzy system (ANFIS) in which membership functions are tuned by using input data of attendants, is applied.

The public pension system in Japan is bringing about intergenerational inequity in contribution / benefit ratio. In this paper, we propose a optimal planing of public pension systems under Generation-based Operation (GO) model and simulate a financial process in proposed method. Proposed method is robust for various disturbances. In society with a decreasing population, the robustness to changes in population is especially useful.

In this paper, we propose a new decision support system for dealing stocks which improves the traditional technical analysis by using neural networks. In the proposed system, neural networks are utilized in order to predict the "Golden Cross"("Dead Cross")several weeks before it occurs. Several computer simulation results confirm the effectiveness of the proposed DSS.

We study about the speech visualization system "KanNon" which supports deaf people's life. To realize speech visualization, the real-time phoneme and syllable level speech recognition system is needed. So we developed the speech recognition systems for speech/silence, voiced/unvoiced and Japanese 5 vowels recognition using neural networks. Finally we show experimental results of our proposed system.

This presentation describes a structure of a robotic program to apply acquired regularities in a sequence. The regularities are acquired by the program, and represented in segments consisting of sensor values and motion instructions. The program, given inputs, uses regularities and calculates where a target is possibly moving before it reaches there.

This paper proposes a control method for a 2-soft-fingered robot hand to grasp and manipulate objects stably and presents experimental results to show the validity of the proposed method. The method not only keeps positional stability of manipulation using a position based control but also controls fingertip contact force with reasonable accuracy taking the elasticity of the soft skin of the fingers into consideration.

We propose an incremental learning model for boosting classifier system whose composite classifier can learn incrementally without serious forgetting. In this system, a designated number of composite classifiers are constructed in advance, and then every classifier is sequentially trained every time when a new training sample is given.

In order to integrate business processes among organizations, this paper presents a case study on university processes and student processes. The university processes extracting from Osaka Prefecture University's Website are organized as Process Handbook proposed by MIT and student processes are organized as work list. Then this paper shows how inter-workflow management tool contributes to synthesizing organization processes.

In order to find out the trend in technical papers, this paper proposes a text mining method. The proposed method is based on the cross tabulation and pattern analysis of LA(Last Appearance) with the conventional TF-DF. Applying the presented method to the transaction papers on quality control, we have found the trend of research topics and its transition.

In this paper, we are concerned with optimization of the observations for the discrete-time Kalman filter. That is, we consider the problem of determining the observation gain matrix in such a way that the esimation error is minimized. Based on a generailzed Water Filling Theorem which was shown recently, we formulate and solve the problem as a local optimization in time.

The methods for plant CG representation are classified roughly intotwo categories, modeling from simulation and from pointrendering. This paper proposes a hybrid method for plant renderingusing both 3D measurement and image-based representation.The proposed approach provides photorealistic appearance with 3D depth effects for the viewer'sperspectives.

Currently, examining staffs manually inspect the eggs for influenza and other vaccine production. However, if demands of sperm egg for manufacture increase such as influenza virus vaccines, it is expected that correspondence becomes difficult. Therefore, the automatic inspection of fertilized egg for vaccine manufacture is necessary. In this paper, we propose a machine vision based fertilized egg inspection system for vaccine production.

In this paper we propose a scheme of digital watermarking based on multi-pulse coding model. First we formulate the multi-pulse coding model. Next we describe two kinds of methods for embedding watermark information into multi-pulse positions. Finally by means of computer simulation, we confirm the effectiveness of our scheme.
