In this paper, we consider a terminal, linear control system with delay, subject to unknown but bounded disturbances. For this system, we consider the problem of constructing a worst-case optimal feedback control policy, which can be corrected at fixed, intermediate time instants. The policy should guarantee that for all admissible uncertainties the system states are in prescribed neighborhoods of predefined system states, at all fixed, intermediate time instants, and in the neighborhood of a given state at a terminal time instant, and the value of the cost function is the best guaranteed value. Simple explicit rules(which can be easily implemented on-line) for constructing the optimal control policy in the original control problem are derived.

Recently, constructing and complementing the road network database are a main key in all social operation in our life. However it needs high expenses for constructing and complementing the data, and relies on many people for finishing the tasks. This study propose a novel method to extract urban road networks from 3-D LiDAR data automatically. This method integrates height, reflectance, and clustered road point information. Geometric information of general roads is also applied to cluster road points group correctly. The proposed method has been tested on various urban areas which contain complicated road networks. The results conclude that the integration of height, reflectance, and geometric information worked reliably to cluster road points.

The purpose of this paper is to provide an algorithm in which the procedure of constructing a superstate transition matrix for trellis codes is reduced and, as a result, make it easier to evaluate the performance of a TCM scheme when the generalized transfer function method is used. In this paper, an algorithm for constructing a superstate transition matrix and an algorithm for reducing the matrix easily are addressed and applied to an MTCM scheme as an example. It is shown that the algorithm is very useflul for trellis codes with a large number of states and/or parallel transitions.
