A "slicing structure" or a hierarchical partition of the display space is an efficient way to present photo collections. However, with different aspect ratios or areas of basic blocks, the prevalent framework creates a number of irregular dead spaces that remain unfilled. In this paper, an efficient solution to reduce or completely eliminate these dead spaces is developed by globally adjusting...
In this paper, we propose a method of non-factoid Web question-answering that can uniformly deal with any class of Japanese non-factoid question by using a large number of example Q&A pairs. Instead of preparing classes of questions beforehand, the method retrieves already asked question examples similar to a submitted question from a set of Q&A pairs. Then, instead of preparing clue expressions...
An equivalence class, called the T-equivalence class in this study, is introduced for discrete time models of a continuous time system such that any member of this class has the same input-output characteristics when the discrete time interval approaches zero. This concept provides a systematic way of viewing the various discrete time models including those already proposed in the literature.
Kharitonov's Theorem, shown first in a Russian literature only within this decade, gives an exact stability condition for polynomials with perturbed coefficients. This theorem seems to have enormous potentialities in the analysis and design of robust control systems. In this paper, an attempt is made to extend the theorem to cover a class of time-delay systems. The results obtained are applied to...
