The abstract of Fiber Optics and Holography:

Most of the fiber optics applications are centered at the TEMPORAL domain application, as applied to communication and sensing, and they are rarely exploiting the SPATIAL content for signal transmission and detection. We shall in this talk to show by the application of holographic technique, the spatial domain of an optical fiber can be utilized for information transmission and for sensing.  Sample examples such as; spatial information transmission through fiber using holographic phase-conjugator, fiber specklegram sensor, tunable filter,  true-time delay lines, and application to phase array antennas will be described.

 

The abstract of Neural Networks and Education:

To cope with the current rapid advances of science and Technology, we may have to educate our students differently than ever before. The fact is that, the brain (or neural net) that we have inherited is not designed to behave like a computer; otherwise we won’t develop the computer. As we have experienced, the more we try to remember the more we cannot remember. Therefore one should not encourage remembering too much, otherwise one would waste one’s effort.  In order to achieve the quality of education, we need to exploit the natural ability of our neural net. Quality of education comes from two major aspects: namely, teaching and learning effectiveness. To achieve these goals, we should use more and more the innovative teaching & learning process. For example, we should provide the learners with simple but significant concepts. And the learners should prepare to accept them using their associative & cognitive learning ability. In this talk, profound relationships between education and neural networks will be discussed and demonstrated.
