    ABSTRACT: This paper presents a dynamic range enhanced visual sensor circuit and its application for multi-object detection based on LGMD (Lobula Giant Movement Detection) method. The proposed visual sensor incorporates a DR (Dynamic Range) extension circuit with the general pipeline AD Converter. Therefore little changes are needed to achieve the DR extension. Together with the modified LGMD model, our system would effectively enhance the reliability of motion detection compared with traditional motion detecting system.

    ABSTRACT: Computational verb cellular network (CVCN) is a new kind of cellular computational platform where the local rules are computational verb rules. In this paper, the mechanism of forming checkerboard patterns in one-dimensional CVCN (1D CVCN) is studied mathematically. Three conditions of generating checkerboard patterns are proved mathematically based on the decomposition of global evolving patterns.

    ABSTRACT: In computational verb(CV) image processing, the evolving function of a spatial verb denotes the changes of gray- values along spatial coordinates. The spatial configurations and the changes of the brightness function as two kinds of the evolving functions of spatial verbs. In our previous work, gray level profiles and contour shapes were used to construct edge models for describing edges of image, and then, achieved the CV interpolation algorithm by using computational verb similarities. In this paper, CV interpolation will be extended to color images, make up the current lack of effective edge detection algorithm and interpolation algorithm for color images. Experiments show that, CV interpolation algorithm has good performance for color images, in the case of a fixed magnification, high resolution image quality is better than other algorithms.

    ABSTRACT: In this paper, a new image interpolation algorithm is proposed due to the inspiration of knowledge-based learning and dynamical control strategy which are based on computational verb theory. This algorithm takes gray level profiles and contour shapes as two processing factors. Experiments show that, with respect to the performance near edges of digital images, our algorithm is better than nearest neighbor interpolation algorithm; with respect to the performance in regions of images, our method is better than bilinear interpolation and bicubic interpolation.

    ABSTRACT: Computational verb cellular network(CVCN) is a new kind of cellular computational platform where the cellular rules are computational verb rule. CVCNs are good models for modeling human social interactions with high-level modeling of human rational and irrational behaviors. Since the richness of patterns formed in 2D CVCNs, the mechanism of forming patterns is difficult to study mathematically. In this paper, the circumgyration patterns formed in 2D CVCN are studied. Based on computational verb local rules, mathematical equations are constructed to define the circumgyration solutions of 2D CVCN. The solution is calculated numerically using Matlab to verify the usefulness of the theoretical predictions.

    ABSTRACT: Computational verb clustering algorithms (shortly, CV clustering) classify historical data by mapping dynamic processes evolving along spatial or temporal axis to the three-dimensional attribute space. This kind of processes exactly meets the character of latent faults emergence evolution. In this paper, template computational verbs are clustered based on sampled CO concentration data, characteristic gas monitored in oil-immersed transformers, in which evolving data of latent fault are utilized fully. And a decision tree is established innovatively according to the corresponding relation between the similarities of each clustered category and detection rates. Simple fault diagnosis is realized preliminarily. Copyright c ⃝ 2010 Yang's Scientific Research Institute, LLC. All rights reserved.

    ABSTRACT: In this paper, a new method for analog design reuse during technology migration is proposed. Previous works ignore the variance of technology parameters. Accordingly, bases on gm/id methodology and ACM model, our methodology adopts an extra pre-extraction step for parameters deciding. This enables a practical description of MOS transistor working state and is therefore more precisely in deciding the design freedoms of two typical strategies. The methodology is validated and results are compared with a common-source amplifier from 0.6um to 0.35um technology.

    ABSTRACT: The probability of a conventional event that consists of a static verb such as be, stay, remain and its contexts can be easily found. However, to derive the probability of a verb event stated by a non-static verb is not as simple as conventional events. In the paper, we introduce a type of evolving function called observation function and address a measure to attain the probability of the verb event via observation functions.

    ABSTRACT: PID controllers were widely used in real-life applications due to their advantages over other kinds of controllers. At the same time, fuzzy controllers have been developed as an important branch of intelligent controllers recently. They also gain good performances in general. However, they can not meet the demands as the system becomes more and more complex. In this paper, computational verb theory is used to improve fuzzy PID controllers. As examples, the control performances of both fuzzy and computational verb PID controllers for controlling fuel annealers are studied.

    ABSTRACT: In this paper, an auto-focusing system of microscope for integrated circuits (IC) analysis is presented. In this system, the Laplacian algorithm is used as the evaluation function, which provides a reference to the degree of defocus. The auto-focusing controlling algorithm based on computational verb theory consists of two controllers designed: the moving-speed controller and the moving-direction controller. Both controllers work well under the verb-control rules designed in this paper. It has shown that the system can focus accurately and quickly, and it can adjust itself when it is out of focus.
