A local enhancement method to distinguish target direction

Zheng Zhang Zhipeng Liu

In order to solve the problem that the peak of the weak target in the azimuthal energy spectrum is lower than the background when using the passive sonar systems to detect targets, and it is unable to identify the target azimuth visually and quickly, a post-processing method that can identify the target azimuth and perform local enhancement is proposed in this paper. This method uses background equalization technology to compress the dynamic range of the energy spectrum. The background threshold of energy spectrum after normalization processing is estimated, and target azimuth is extracted. Combined with the background threshold, the correction coefficient is constructed in segments to achieve the local enhancement at the target azimuth. This method is able to distinguish targets and background visually and quickly, has the function of highlighting and identifying the azimuth of the target based on simulation and measured data.

Trial Teaching of Communicative Approach for Nurses

Overseas English (2010)

Zheng Zhang

The main requirement of English teaching for nursing is to train students' synthetic standard and ability of communicating with patients in English.Communicative approach in English teaching can improve students' interest and motivation of learning English.Practical games and harmonious atmosphere in English class will lead students to learn throw use.And it can improve students' English level and ability to communicate with foreigners also.

Experimental Evaluation of a Tele-Operated Robot System in Traversing a Narrow Path

2022 IEEE International Conference on Mechatronics and Automation (ICMA) (2018)

Zhefu Du Zheng Zhang Yuta Naito Satoru Miki Nobuto Matsuhira

Tele-operated robot systems are expected to greatly assist humans in dangerous environments, such as natural disaster sites. Thus, we have developed a mobile robot system that is tele-operated via the Internet from any location and is capable of traversing narrow paths. Herein, we developed a control algorithm for traversing a narrow path and experimentally verified the ability of the robot iws09 which was 370 mm in diameter, to automatically pass through a narrow path having a clearance of 40 mm on both sides without collisions. Furthermore, the wheel-driving characteristics of the robot were verified. The function of traversing a narrow path will be helpful to support an operator remotely controlling the robot. Next, we will develop a mobile robot control system to cope with other situations.

Improvement in diversify active defense for web application by using language and database heterogeneity

Weichao Li Zheng Zhang Liqun Wang

According to OWASP selected web application Top 10 vulnerabilities in 2013 and 2017, structured query language (SQL) injection is consistently ranked the 1st. Therefore, the protection of SQL injection, which is one of the most prevalent and pernicious security issues, requires strengthening. Furthermore, there are numerous unknown vulnerabilities and potential threats in cyber-space. In this case, the active defense based on structural diversity can play an effective role to prevent the hacker from exploiting known or unknown vulnerabilities. And on the basis of structural diversity, we propose a modified method, heterogeneous language, combined with heterogeneous database in data storage layer, to establish an active defense model for data security. We empirically assess the impact of the vulnerability and conclude by testing the accuracy and performance, showing that our security model can not suffer from the same vulnerability as the unprotected one. Finally, the future work and research direction are discussed.

Construction of Curriculum System for Automation Based on Complicated Project Problems

Wei-Hua Huang Bin Liu Zheng Zhang

Cultivating students with the ability to solve complicated engineering problems isn't only important for engineering education professional certification (EDPC), but also for higher engineering education in China. Taken the major of automation in Wuhan University of Science and Technology as an example, a curriculum system is implemented on the basis of ideas and requirements of EDPC. And then a quality process management system with feedback control theory is proposed to ensure the training quality of students. Finally, the impacts of training on the students ' ability of solving complicated engineering problems are illustrated which enhance the students' learning outcomes and provide a reference of engineering education professional certification for relevant specialties.

Phage protein receptors have multiple interaction partners and high expressions

Bioinformatics (2020)

Zheng Zhang Fen Yu Yuanqiang Zou Ye Qiu Aiping Wu

Receptors on host cells play a critical role in viral infection. How phages select receptors is still unknown.Here, we manually curated a high-quality database named phageReceptor, including 427 pairs of phage-host receptor interactions, 341 unique viral species or sub-species and 69 bacterial species. Sugars and proteins were most widely used by phages as receptors. The receptor usage of phages in Gram-positive bacteria was different from that in Gram-negative bacteria. Most protein receptors were located on the outer membrane. The phage protein receptors (PPRs) were highly diverse in their structures, and had little sequence identity and no common protein domain with mammalian virus receptors. Further functional characterization of PPRs in Escherichia coli showed that they had larger node degrees and betweennesses in the protein-protein interaction network, and higher expression levels, than other outer membrane proteins, plasma membrane proteins or other intracellular proteins. These findings were consistent with what observed for mammalian virus receptors reported in previous studies, suggesting that viral protein receptors tend to have multiple interaction partners and high expressions. The study deepens our understanding of virus-host interactions.phageReceptor is publicly available from: http://www.computationalbiology.cn/phageReceptor/index.html.Supplementary data are available at Bioinformatics online.

Succeed and Develop Luying's Aesthetic Thought

Zheng Zhang

Luying's aesthetic thought possesses great importance.To further develop Luying's aesthetic thought,you should set to work from the following: Ⅰ.To make sure the aesthetic value from the actual connection of the objective object and human,get the reflected contents of aesthetics to fall to the ground. Ⅱ. Make the problem of aesthetic value get the scientific concrte comprehension through making sure the entitative connection from the practice and human. Ⅲ.The foundation of aesthetic enjoyment is aesthetic value.Know aesthetic enjoyment with the dialectic unification relationship between human's aesthetic experience and human's aesthetic evaluation. Ⅳ.With the aesthetic value as the logic starting point,estabilsh the philosophizing system of the Chinese modern aesthetics.

Top-k Keyword Query on Uncertain Database

Zheng Zhang

The problems of keyword search on relational databases and uncertain data management have been considered extensively,however addressed in isolation in the past.This paper introduces a novel method that combines IR-style keyword query with uncertain relational databases,and defines an uncertain model and its query semantics.The paper also shows a top-k algorithm to perform keyword search query on the attribute level,and return k query results which have maximum rank scores.Rank score of a query result is well-defined,depending on its correlation with query Keywords and its possibility under the possible world.An optimized algorithm is introduced to reduce the complexity of the top-k query.The experimental results demonstrate the practicality and efficiency of these methods.
