    ABSTRACT: In this paper an improved algorithm of computational verb PID controller is proposed. In the original design of verb PID controller, the modification of integral gain is coupled with that of the derivative gain. In this paper, the integral gain is modified independently by using a separated set of computational verb rules. The comparisons of tracking performance and robustness among conventional PID controllers, fuzzy PID controllers, verb PID controllers and the proposed verb PID controllers are presented. The simulation results show that the improved verb PID controller is better than other three kinds of PID controller with respect to tracking performances.

    ABSTRACT: Different with traditional way to detect the barcode with laser scanner, another cheaper and portable method is using the camera with the image processing algorithm. It is convenient today to use the camera of cellphones to detect the barcode. With digital image processing techniques based on computational verb theory was proposed before, in this paper, a barcode localization algorithm based on verb image processing is introduced. It combines traditional image processing techniques with computational verb image processing for object detection. The proposed algorithm shows a robust performance in the experiment, which uses a database containing over 1,000 barcode images under different environmental conditions.

    ABSTRACT: Gas recognition techniques are important for metal oxide sensors in practical applications because of their poor selectivities. The conventional solution is using sensor arrays instead of single sensors for pattern recognition. But this solution is expensive and the accuracy is affected by every single sensor in it. So developing recognition techniques based on single sensors is strongly needed. In this paper, a new method based on computational verb theory was developed by employing verb similarities as decision features and a clear linear decision boundary was found. Precise recognition between ethanol and acetone was conducted by using a single sensor. Compared with the conventional gas recognition approach, this method is more cost effective and programmable which shows promising applications in future smart gas detecting systems.

    ABSTRACT: Computational verb cellular networks (CVCNs) are a new kind of cellular computational platform where the cellular rules are computational verb rules. Since the richness of computational verb rules, CVCNs are of many kinds. In the previous works, the categorizations of patterns formed in two-dimensional computational verb networks (2D CVCNs) with Moore-neighborhood were studied. In this paper, we use T-neighborhood, in which we just need to consider the center cell and three neighbor cells directly upon it. In T-neighborhood we observed many dynamic transmitting patterns and some special patterns that seem to be unchangeable and static of 2D CVCNs.

    ABSTRACT: There are many algorithms for association rule mining, but in practice we usually face raw data that is inappropriate for these algorithms because of lacking a unified preprocessing framework. In this paper, a general framework for dynamic data processing is presented, which is based on computational verb theory (CVT). Linear standard computational verbs are used and computational verb similarities are employed to process raw data, such that the association rules of trends can be found. One example of time series of an Internet shop is studied to show the usefulness of the association rule mining algorithm proposed in this paper.

    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: In this paper, on the basis of the computational verb theory, we set special local verb rules and specific initial conditions to try to simulate some phenomena in two dimensional computational verb cellular networks then we get some diffusion and wave propagation patterns. We pick up three typical types to be shown in this paper, that is, ripple propagation patterns, target wave propagation patterns and diamond propagation patterns. And we use ripple propagation patterns to model raindrops ripple. Compared to the traditional physical methods of water wave modeling, the 2D CVCNs could model the phenomena by an easier way. The models which are based on the 2D CVCN reveal that computational verb cellular networks have good capabilities for physical modeling.

    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: 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: In this paper, computational verb theory (CVT) is applied to the analysis of stock market data. By using CVT, stock market data are clustered into different categories and represented by typical curves for each category. In this paper, researches on the market data samples from Shanghai Stock Exchange in March 2010 are reported. Firstly, MATLAB programs are used to preprocess the stock data. The preprocess consists of curve smoothing, which is achieved by low-pass filtering, and normalization. Secondly, computational verb similarities are used to process the smoothed time series by comparing them with standard computational verbs. Thirdly, Kmeans clustering algorithm is used to cluster the stock data and yields the most representative curves in the stock market.

    ABSTRACT: The development and evolution of vocabulary is a very complex and dynamic process. The development of Chinese vocabulary is mainly that the monosyllabic words in ancient Chinese gradually evolved into disyllabic and polysyllabic words in modern Chinese. This paper attempts to analyze the evolving mechanism of computational verbs in Chinese, including merge of verbs, split of verbs. Furthermore, computational verb theory was used to build the mathematic models of new Chinese verbs. The experiments were constructed to help analyze the changes in semantic meaning when Chinese verbs merge or split. Based on these experiments, the interactions among Chinese verbs and their consequences were studied mathematically.

    ABSTRACT: Computational verb numbers, as a special kind of computational verb, play an important role in designing computational verb gain-scheduling PID controllers. In this paper, computational verb numbers in the form of “computational verb + real number” are used to construct control rules of PID controllers, and a composed computational verb similarity is designed for computational verb reasoning. Simulation results are shown to compare with conventional PID controllers and fuzzy gain-scheduling PID controllers, demonstrating that the new type of computational verb PID controller has satisfactory tracking performance.
