Radius blends, very important in geometric and solid modeling, can be seen as the trimmed envelope of a rolling sphere or a sweeping circle with a constant or variable radius that centers on a spine curve and touches the surfaces to be blended along the linkage curves. Usually, in variable-radius blending, the radius is difficult to specify, and the spine curve is hard to trace. We propose several geometric constraints to specify the variable radius, which we then translate to a nonlinear system to represent the spine curve exactly. This is finally traced numerically in a high-dimensional space. We also propose a paradigm that implements the constraints while tracing along the spine curve in 3D space. We represent the result in parametric form.
A fault tolerant shared memory ATM switch

In this paper, we present a fault tolerant ATM switch based on the shared memory architecture [6]. We study first the effect of a single fault to an ATM switch. Basically, a single fault in an ATM switch results in cell mis-delivery, out-of-sequence, corruption, and/or loss. We propose to add output port address, sequence number, and CRC checking to each cell for on-line fault detection. Some single faults which cause cell loss cannot be detected without wing multiple switch copies. Therefore, we propose to we a duplex system for detecting these faults and also for fault tolerant. We then design a fault tolerant switch based on the shared memory architecture [6]. Our proposed implementation can tolerate a single fault without losing cells in most cases.

交大名義發表
In real applications, data provided to a learning system usually contain linguistic information which greatly influences concept descriptions derived by conventional inductive learning methods. The design of learning methods to learn concept descriptions in linguistic environments is thus very important. In this paper, we apply fuzzy set concepts to machine learning to solve this problem. A fuzzy learning algorithm based on the maximum information gain is proposed to manage linguistic information. Experiments on the sport classification problem are to demonstrate the effectiveness of the proposed algorithm. Experimental results show that the rules derived from our approach are simpler and yields high accuracy.

Dynamical analysis of survival of Kosterlitz-Thouless pairs due to pinning

We investigate the process of annihilation between vortices of opposite flux in superconducting thin films in the presence of randomly distributed pinning centers. The number and distribution of pairs of vortex-antivortex that avoid annihilation due to pinning on two pinning centers is estimated analytically and compared with numerical simulations. The situation can be realized, for example, when the system is quenched from high temperature (above or below the Kosterlitz-Thouless temperature) or when the current is reduced abruptly. Qualitatively two different cases can be distinguished. The simpler one is when the pairs are well separated. In this case, the problem under mild assumptions can be solved analytically. When the vortex pairs are not very rare, the situation is much more complicated because a great variety of processes become significant. We isolate the important ones and construct an iterative (real-space renormalization-group) scheme to describe the behavior of the interacting multivortex system. Some dynamical aspects of pinning and vortex motion are discussed.
Plane wave scattering by crossed metal-strip gratings

The plane-wave scattering by two crossed metal-strip gratings is formulated as a three-dimensional boundary-value problem, taking into account the polarization couplings. It is found that a large range of crossing angle between the two gratings will meet the shielding requirement in practice, regardless of the incident conditions.

Thiobacillus novellus, like other facultative chemoautotrophs, possesses the unique ability to grow autotrophically as well as heterotrophically. Since in nature the bacteria are likely to encounter different environments, i.e., autotrophic, heterotrophic, or mixotrophic conditions, it is of considerable interest to determine the removal characteristics of H2S in different environments. Thiobacillus novellus CH 3 was isolated from piggery wastewater and used to remove H2S gas from air in this study. The results indicated that the Thiobacillus novellus biofilter under mixotrophic conditions possessed broad adaptability of pH (5 - 10) compared to the one under autotrophic conditions. In a batch experiment high H2S concentration (>140 ppm) inhibited the enzymatic activity, thus the H2S removal was limited by the reaction rate rather than the diffusion rate at diluted H2S concentration. During the environmental shock experiment, 99.5% of the H2S content from the inlet was eliminated in a misotrophic environment, but only 97.5% was eliminated in an autotrophic environment. Moreover, the misotrophic biofilter possessed higher removal capacity than the autotrophic biofilter. Thus, the results suggest that the potential of Thiobacillus novellus CH 3 in the mixotrophic environment should be of selective advantage over the cells in the autotrophic environment.

In group technology, workpieces are categorised into families according to their similarity in design or manufacturing, attributes. This categorisation can eliminate design duplication and facilitate the production of workpieces. Much effort has been focused on the development of automated workpiece classification systems. However it is difficult to evaluate the utility of such systems. The objective of this study was to develop a benchmark classification system based on global shape information for. use in evaluating the utility of workpiece classification systems. A classification system has a high level of utility if its classification scheme is consistent with users perceptual judgement of the similarity between workpiece shapes. Hence, in the proposed method, the consistency between a classification system and users' perceptual judgements is used as an index of the utility of the system. The proposed benchmark classification has two salient characteristics: 1. It is user-oriented, because it is based or? users' judgements concerning the similarity of the global shape of workpieces. 2. It is flexible, allowing users to adjust the criteria of similarity applied in the automated workpiece classification. The development of this classification consisted of three steps. 1. Gathering row data on global shape similarity from a group of representative users and modelling the data by fuzzy numbers. 2. Developing benchmark classification for various similarity criteria by rising fuzzy, clustering analysis. 3. Developing indices for evaluating the appropriate number of workpiece categories and homogeneity within each group. The applicability of the benchmark classification system in evaluating the utility of automated workpiece classification systems was examined.
