SCCP Sake - an Image Processing Application
The project ``Sake'' is a joint effort of the Image Processing and Computer Industry Laboratories of the University of Aizu together with the industrial partner Aiko Engineering, Inc. Hanaharu is one of the famous sake companies in the Fukushima Prefecture. The production process is widely automated. The step of quality control/insurance, however, has not yet been computerized. Workers are sitting in front of the line, looking at the bottles and picking out the bad ones. The speed of the line is very high and the work very tiresome. They have to change the workers at these positions every 10 to 20 minutes. The goal of our University is to Advanced Knowledge for Humanity. With image processing technology, the procedure for quality insurance can be automated. The production process will then be less tiresome for the human workers. For developing the TIP image processing system, Parsytec, Inc. is used which has in the basic configuration 3 transputers, framegrabber, and CCD.
Intelligent Dental Care System
The Intelligent Dental Care System (IDCS) is a joint effort with several laboratories of the university and some consulting dentists under the leadership of Prof. T. L. Kunii. The research is focused on computer-aided production of ceramic dental restorations, diagnosis for occlusal therapy and treatment and protocoling with the use of a database. The IDCS project is funded by the Fukushima Prefectural Education Development Foundation.
The main task is to develop a CAD/CAM system for design and fabrication of teeth restorations which is preserving occlusal contacts.
The user interface - emphasis of the Computer Industry laboratory - exploits metaphors that are familiar to dentists from everyday practice. A new input technique designed specifically for use with articulation simulation is under development.
A computer articulation simulation checks the designed restoration following fast automatic adjustment. Another goal is articulation problem diagnosis. The idea is to detect articulation problems in more detail than is possible using traditional approaches, such as use of mechanical articulators and tapping paper. The system is also used for planning treatment, evaluating automatically the results of various versions of virtual treatment. Objectives are speedup of restoration design and manufacturing (ideally a single visit to the clinic should be sufficient to complete treatment) and reduction of human labor (possibly eliminating dental technicians all together). It is achieved by:
Unrefereed Papers
Others
A regular seminar of the `Multimedia Communication and Quality of Service' (MM&QOS) research group has been established in the Computer Industry Laboratory. Quality of Service can be defined as a description of the level of application, network, and hardware. These definitions can be used for exception handling on the application site, specification of requirements to the system and automated requirement verification. The research group will focus mainly on the expression of the relationship between time and the semantics of the application.
A model describing convergence of genetic algorithms has been developed on the basis of homomorphisms of fuzzy sets. Compare H.H. Schaefer, Banach Lattices and Positive Operators, Springer Verlag, Chapter I.
A semiclassical theory of interband tunneling in semiconductor heterostructures was given by V. Ryzhii and A. Zhakharova in Semicond. Sci. Technol. 8 (1993), 377-382. We use this theory to give a study of the solutions to the associated Schroedinger equation for multi layer heterostructures by means of computer algebra. This yields a method to obtain an error estimate for the approximate solution of the Schroedinger equation and gives new insight into interband tunneling in semiconductor heterostructures.
