Set-membership Estimation for Event-triggered 2-D Systems Based on Zonotopes
Xudong Wang,Guoqi Wang,Liu Yang,Jitao Li 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.3
This article discusses the interval estimation for 2-D systems in Roesser model with amplitude-boundedenvironmental disturbance and measurement noise. To save the limited capacity of communication network, anevent-triggered communication strategy is adopted to reduce the amount of packets transmitted through the network. Considering the amplitude-bounded uncertainties, an observer design criterion with peak-to-peak norm boundis deduced to suppress the influence of uncertainties on estimation error. A zonotope-based interval estimation approach is derived such that the actual state of 2-D Roesser system is enclosed within the estimated intervals on thebasis of the obtained observer. Finally, a numerical example is presented to verify the effectiveness of the proposedalgorithm
Pedestrian Detection Algorithm Combining HOG and SLBP
Aili Wang,Mingxiao Wang,Jitao Zhang,Yuji Iwahori,Bo Wang 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.10
In order to solve the problem of pedestrian detection performance, the described operator was improved. In this paper, semantic local binary pattern (SLBP) and histogram of oriented gradient (HOG) are combined as new feature operator. This feature method would enrich the information and enhance the detection performance. And then histogram intersection kernel support vector machine (HIKSVM) classifier is trained by the augment feature. Because the time cost is too large by the conventional SVM. HIKSVM could make up this drawback, and significantly reduce the training time. The experiments on the INRIA pedestrian dataset show that the method obtained significant improvement in accuracy comparing to HOG descriptors.

Jitao Li,Zhenhua Wang,Yi Shen,Yipeng Liu 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.1
This paper studies unknown input observer design for discrete-time Takagi-Sugeno fuzzy systems. Theproposed unknown input observer has a new structure that can be applied to Takagi-Sugeno fuzzy systems withnonlinear output equation. We derive the design conditions of the proposed unknown input observer based onLyapunov function and convert them into a set of linear matrix inequalities. Numerical simulations of a vehiclelateral dynamics are given to illustrate the effectiveness of the proposed method.

Jitao Zhang,Aili Wang,Jiaying Zhao 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.10
Image fusion is an important branch of information fusion, which is widely used in various fields. At present, the image fusion method is mainly aimed at the different frequency information of the images, the images are fused in transform domain. But in practical application, image fusion is used to improve the credibility of the target information and the demand of background information of is not high. Therefore, this paper puts forward an image fusion method combining with image classification. Firstly, the NSCT transform is used to transform the source images, and the K-Means method is used to realize the classification of the target and the background, and the different fusion criteria are used to get the target and the background. The experimental results show that the image fusion based classification method has a better effect on the subjective visual effect and objective evaluation index.
A Review of Advances in Triaxial Tests: Instruments, Test Techniques and Prospects
Jitao Bai,Yu Diao,Chenhang Jia,Chongyang Liu,Menghan Zhang,Chu Wang 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.8
Triaxial test is approved to be the most suitable method for studying the mechanical properties of rocks and soils in lab. Through conventional triaxial tests, parameters like the strength of rocks and soils can be obtained, thus providing guidance for the design and construction of geotechnical engineering. With the development of geotechnical engineering, more and more new problems that can hardly be solved by conventional triaxial tests have arisen, which can be classified into two categories: one is the mechanical properties of special soils (rocks), and the other is the mechanical properties of the soils (rocks) under special conditions like geologic hazards and multi-field coupling. The paper introduced several new types of triaxial instruments and test techniques developed in response to the problems, and prospects have been made for further study of triaxial tests, which may provide reference for the optimization of triaxial tests.

The ridgetail white prawn Exopalaemon carinicauda is one of the major commercial mariculture species in eastern China. However, only limited molecular markers are currently available due to the lack of genome information, which hinders its genetic and breeding studies. In this study, we identified new simple sequence repeats from transcriptome sequences by Illumina Hiseq 2500 platform. A total of 14273 SSR loci were identified from 130,082 assembled transcripts, with 6590 pairs of PCR primers designed. A total of 12,155 sequences containing SSR were predicted; and 2764 (22.74%) transcripts had significant matches to the NCBI non redundant protein (Nr) database. 11,563 transcripts were assigned into gene ontology (GO) categories. A set of 200 primers selected randomly were synthesized, of which 152 (76.0%) were successfully amplified. Further test with 60 pairs of polymorphic SSR primers to evaluate the genetic diversity of 30 wild populations and 43 loci were polymorphic, which had a polymorphic information content between 0.204 and 0.911. The results enriched genomic resources of E. carinicauda and provided powerful information for future conservation and breeding researches.

Clostridium perfringens epsilon toxin (Etx) is an extremely potent toxin, causing fatal enterotoxaemia in many animals. Several amino acids in domains I and II have been proposed to be critical for Etx to interact with MDCK cells. However, the critical amino acids in domain III remain undefined. Therefore, we assessed the effects of aromatic amino acids in domain III on Etx activity in this study. All of the results indicated that Y71 was critical for the cytotoxic activity ofEtx towards MDCK cells, and this activity was dependent on the existence of an aromatic ring residue in position 71. Additionally, mutations in Y71 did not affect the binding of Etx to MDCK cells, indicating that Y71 is not a receptor binding site for Etx. In summary, we identified an amino acid in domain III that is important for the cytotoxic activity of Etx, thereby providing information on the structure-function relationship of Etx.

At present, almost all hybrid excitation machines (HEMs) apply DC field current to control the air-gap flux. However, the DC field control mode results in a problem that the capability of field-weakening is not equal to that of field-strengthening. This paper briefly explains the mechanism of asymmetric bidirectional field control capability in present HEMs, proposes a consequent pole hybrid excitation synchronous (CPHES) machine with AC field control mode to solve the asymmetric problem. The structure and principles of CPHES machine are presented. Additionally, the equivalent magnetic circuit model of CPHES machine is derived to reduce the computational complexity of analyzing CPHES structure by using three-dimensional finite element analysis (3DFEA). The proposed equivalent model and 3D-FEA are compared, the results verify the proposed model is basically consistent with the 3D-FEA, and the proposed model is able to reduce the computational complexity greatly.

Jing Wu,Yang Tang,Zengliang Shi,Zhengshan Tian,Junhua Wang,Chi Yang,Jitao Li,Zhongdang Xiao,Chunxiang Xu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.7
Viability of cancer cell is an important indicator of physiological state and function of cells, which can be effected by the change of pH in the medium solution, due to the increase of carbon oxide and lactic acid caused by respiration. Although many methods have been developed to detect the viability of cells, mostly based on cytochemical staining and polymerase chain reaction (PCR) technology are time consuming. In this paper, an electronic device was made by thermal reduced graphene oxide (RGO) for detection of cancer cell viability in real-time. This electronic device could be used to monitor the metabolic activity and viability of cancer cells based on the change in pH value. As the pH decreases, colon cancer cells loose viability and the current decreases. This RGO device is simple, sensitive and label-free and could serve as a platform for detection of cells and drug testing.
