On-line robust control based on a stability index for time-delay systems has been developed. The purpose of the proposed design algorithm is to on-line tune a filter in the control loop. The problem of robust control with an incorrect given bound on the modeling error is investigated. Illustrative examples are presented to show the promise of the proposed method.

The aim of this study is to evaluate the public preference to the breakwaters of fishing harbors in Taiwan, so that the results could be applied to the successive study of breakwater landscape improvement. Among the breakwaters' photographs those took on the fishing harbors, this study picked up 4 photos for demonstration and 60 for questionnaire according to their spatial types configured with crest of breakwater, crown wall, and armoring blocks) and other landscape factors. The preference evaluation was conducted by questionnaire to the public, 385 effective questionnaires were taken into analysis. Results reveals: (1) the open, colorful, recreational and water-intimate breakwaters are preferred. (2) The combination types and visual elements (shapes, colors, textures, lines and scales) of breakwaters are also influence the public preference.
