Conventional iris recognition using a full frontal iris image has reached a very high accuracy rate. In this paper, we focus on processing off-angle iris images. Previous research has shown that it is possible to correct off-angle iris images, but knowledge of the angle was needed. Very little work has focused on iris angle estimation which can be used for angle correction. In this paper, we describe...
We consider two synchronization problems, namely, state synchronization for networks of identical linear agents, and regulated output synchronization for networks of non-identical linear agents, under a time-varying topology. Agents are assumed to be multiple-input multiple-output (MIMO), minimum-phase, right invertible and non-introspective (i.e., they only receive relative output information from...
Objective: To establish a syndrome differentiation model and program of Traditional Chinese Medicine (TCM) based on fuzzy recognition. Method: According to the syndrome differentiation system of five zang-organs, combined with approaching principle in the fuzzy mathematics, the fuzzy recognition model of heart system basic syndrome was established first, and then the program was designed based on...
In this paper, computational verb correlation (verb correlation, for short) is applied to stock market in order to find the correlation between different stock indexes. In previous works, computational verb similarities are used to provide the measurement for selecting the attributes in order to train decision trees. In this paper, a training method of decision tree is constructed based on verb correlation...
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...
Self/Non-self discrimination is the basic mission of the artificial immune systems (AIS). In traditional AIS, detectors discriminate non-self elements based on the Minkowski distance between detectors and antigens. However, in high dimensional feature space the distances between elements converge to a similar value, so the data discrimination will become much difficult. In this article, the relationship...
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 networksthen 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...
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...
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...
With the society's advocacy of "low-carbon energy-saving" way of life, saving energy has been a heated topic. Although the street lamp is an indispensable part of the basic facilities of a city, its large energy consumption at present has wasted a lot of natural resources. In order to solve this problem, many scientific researchers provide many solutions by using software or hardware methods...
A new phase measurement based on the six-port technology is introduced in this paper and compared with the conventional superheterodyne phase detector. The six-port architecture adopting zero-intermediate frequency architecture, consisting of the six-port junction, detectors, video amplifiers and other devices. It has been proven to reduce the difficulty of the system-design and have vast value for...
A C-band (5.5GHz) six-port junction is proposed. The six-port junction, composed of one power divider and three 90° hybrid couplers, is the key of the new direct digital receiver which will satisfy the mass-market wireless communication systems and radar requirements. This kind of receiver consists of a six-port junction, RF detectors which run in the square-law characteristics, video amplifiers and...
Image segmentation is one of the classic problems in the computer vision field. Although a lot of successful operators and algorithms have been proposed, fuzzy image segmentation does not always achieve satisfactory results. This paper is inspired by Positive Selection Algorithm and Negative Selection Algorithm and, is based on the mechanism and process where T-cell is activated by the MHC molecule...
This essay discusses about the numerous problems existing today in relation to the education of basis of computer engineering in university, based on the investigation and analysis of the level of basic computer knowledge of freshman during their first semester from 2008–2009 in Shenyang Agriculture University. It proposes practical methodology of education and teaching reform against these conflicts...
Compared with logistics of ordinary things, Chemical Logistics is flammable, explosive, toxic and corrosive and other characteristics. Storage and transport of specialty chemicals has inevitably brought a series of serious problems and potential problems because of its particularity, so the safety of chemical logistics management is very important. How can the implementation of the chemical products...
Private attributes of Online Social Network (OSN) users can be inferred from other information (which is usually from users' friends and group information). To address this, social networking sites allow users to hide their friend lists and group lists, so that general public cannot see them. However, if a user doesn't make his friend list public, but his friends have public friend list where we can...
This paper attempts to establish the synthetic evaluation index model, utilizes fuzzy analysis to analyze Entrepreneurship environment of Heilongjiang Province, and draws the conclusions that Entrepreneurship environment in Heilongjiang Province needs to improve. Considering the problems in the development of entrepreneurship environment, this paper puts forward some suggestion and countermeasures...
A new method based on coupling with shock filters and anisotropic diffusion is presented for image enhancement and denoising in this work. A new improved shock filters term and a new fidelity term, which are produced adaptive magnitude from image structural information, are proposed for the image enhancement and denoising. The method can not only well restrain noise but also enhance edge and keep...
