The zero crossings of the wavelet transform are used to extract the unique features obtained from the grey level profiles of the iris. The recognition process is performed in two stages. The first stage consists of building a one dimensional representation of the grey level profiles of the iris followed by obtaining the wavelet transform zero crossings of the resulting representation. The second stage is the matching procedure for iris recognition. The proposed approach uses only a few selected intermediate resolution levels for matching, thus making it computationally efficient as well as less sensitive to noise and quantisation errors. A normalisation process is implemented to compensate for size variations due to the possible changes in the camera to face distance. The technique has been tested on real images in both noise free and noisy conditions. The technique is being investigated for real time implementation, as a standalone system, for access control to high security areas.","PeriodicalId":166931,"journal":{"name":"Proceedings of 1st International Conference on Conventional and Knowledge Based Intelligent Electronic Systems.

By using the optimization in dimensioning, it is possible to replace the heuristic optimization process of a design engineer in an automated offer calculation system or alternatively to help the engineer in design work. The role of the optimization is to vary a part of the design parameters of a design tool. Heuristic design knowledge and knowledge of the specifications of the machines are utilized. Also, the production tools can be taken into account in the optimization process. The objectives of optimization are described by fuzzy tolerances. In this paper the descriptions of the experiments are explained and the effectiveness of optimization algorithms with different parameters and encoding techniques are studied.","PeriodicalId":166931,"journal":{"name":"Proceedings of 1st International Conference on Conventional and Knowledge Based Intelligent Electronic Systems.

Nguyen","doi":"10.1109/KES.1997.619421","DOIUrl":"https://doi.org/10.1109/KES.1997.619421","url":null,"abstract":"In compliant motion, the task to be performed is usually not well structured and uncertainty exists. The operational environment is either partially known or unpredictable. In applications such as the manipulation of flexible materials, the characteristics of the plant changes during operation. Conventional control methods, therefore, do not provide an appropriate solution for such problems. Intelligent control (IC), in which neural networks and fuzzy control are key components, is employed to produce a self-learning compliant motion. The neuro-fuzzy model of the compliant motion is obtained through Adaptive Spline Modelling of Observation Data (ASMOD) algorithm. This is used as the initial model of the process. An adaptive indirect fuzzy controller is then designed to control and adapt the system parameters on-line. The results are compared with previous work which employed static fuzzy control.","PeriodicalId":166931,"journal":{"name":"Proceedings of 1st International Conference on Conventional and Knowledge Based Intelligent Electronic Systems.

Also, a new adaptive fuzzy controller is presented to overcome the time consuming process of fine-tuning the membership functions.

Application of fuzzy logic and approximate reasoning in process automation 模糊逻辑和近似推理在过程自动化中的应用

D. de Silva","doi":"10.1109/KES.1997.616847","DOIUrl":"https://doi.org/10.1109/KES.1997.616847","url":null,"abstract":"Intelligence encompasses abilities to perceive, reason, learn, and infer from incomplete information. The capability of approximation for the purpose of comparison, pattern recognition, reasoning and decision making, is also manifestation of intelligence. There are many concepts of approximation, examples of which include imprecision, uncertainty, fuzziness, and belief. These concepts are not identical even though the associated methods of information representation and processing may display similarities. The presentation will explore several concepts of approximation, in this context. Advanced automation of industrial processes may require \"intelligent\" monitoring, quality assessment, self-tuning, and supervisory control. The presentation describes several industrial applications where fuzzy logic has been employed in the representation and processing of knowledge for the purpose of \"intelligent\" decision making that is associated with such tasks.","PeriodicalId":166931,"journal":{"name":"Proceedings of 1st International Conference on Conventional and Knowledge Based Intelligent Electronic Systems.
