Novel Tag Anti-Collision Algorithm with Adaptive Grouping  [PDF]
Jun DING, Falin LIU
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.15057
Abstract: For RFID tags, a Novel Tag Anti-collision Algorithm with Grouping (TAAG) is proposed. It divides tags into groups and adopts a deterministic method to identify tags within group. TAAG estimates the total number of tags in systems from group identifying result and then adjusts the grouping method accordingly. The performance of the proposed TAAG algorithm is compared with the conventional tag anti-collision algorithms by simulation experiments. According to both the analysis and simulation result, the proposed algorithm shows better performance in terms of throughput, total slots used to identify and total cycles.
A Social Network Theory of Stakeholders in China’s Project Governance  [PDF]
Ronggui Ding, Fang Liu
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.32017
Abstract: A project, especially for one in China, usually involves many organizations and each organization may have multiple projects. There is a clear social network relationship between these stakeholders in a project and the stakeholders’ behaviors are also subject to the structure of the social network. Based on an analysis of the social network, as a methodology that can be used to explain the relationships among project organizations, as well as an example of large-scale information system project in China, we construct in this article a way to establish the social network of governance structure, study network configurations and analyze some representative governance strategies adopted by stakeholders in China. By examining the network of project governance, we can predict the trend of the project governance structure and study the risk based on the structure.
Experimental Study on Fly Ash for Conditioning of Specific Resistance of Sludge Water  [PDF]
Bingtao Liu, Pengju Ding
Journal of Geoscience and Environment Protection (GEP) , 2013, DOI: 10.4236/gep.2013.12005
Abstract:

Discharge of sludge from water works into waters will result in the increased deterioration of water environment. Therefore, an experimental study was conducted on the addition of conditioning agent to improve sludge dewatering performance. The result shows that coagulation is inadaptable to the treatment of sludge from water works and use of powdered coal ash from power plant as conditioning agent can greatly reduce the specific resistance of sludge and the dewatering performance can be improved. The optimal dosage of fine powdered coal is 20g/100mL and coarse powdered coal is 30g/100mL. Powdered coal is mixed with sludge to form filter cake, which is blended with coal in certain proportion to make into fuel. So that incineration of sludge from water works can be realized.

Numerical Simulation of Emission Characteristics for Single-Cylinder Diesel Engine  [PDF]
Changwei Ding, Weijun Liu
Energy and Power Engineering (EPE) , 2016, DOI: 10.4236/epe.2016.82008
Abstract: First, the geometry model and the calculation mesh of single-cylinder direct injection diesel engine are built, using ESE module of the 3D simulation software AVL FIRE v2014 [1]. Then, by setting appropriate boundary condition, initial condition and calculating step length, and selecting spray, the burning emissions on model and on the basis of adjusting the parameters, a scientific and reasonable simulation platform is built. Emission characteristics of single-cylinder diesel engines in oxygen-enriched, oxygen-enriched + EGR (inlet adding CO2), and separately using EGR would be studied. It is concluded that EGR synergy oxygen-enriched combustion is beneficial to exhaust treatment and 21% CO2 + 23% oxygen content is the optimal matching to improve diesel engine exhaust emissions.
Delay and Its Time-Derivative Dependent Stable Criterion for Differential-Algebraic Systems  [PDF]
Hui Liu, Yucai Ding
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.710100
Abstract:
In this paper, the stable problem for differential-algebraic systems is investigated by a convex op-timization approach. Based on the Lyapunov functional method and the delay partitioning approach, some delay and its time-derivative dependent stable criteria are obtained and formulated in the form of simple linear matrix inequalities (LMIs). The obtained criteria are dependent on the sizes of delay and its time-derivative and are less conservative than those produced by previous approaches.
Volatility Analysis of Web News and Public Attitude by GARCH Model  [PDF]
Pinrui Yu, Tianzhen Liu, Qian Ding
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.38092
Abstract: GARCH (Generalized Auto-Regressive Conditional Heteroskedasticity) model proposed by Professor Engle is successful to analyze the volatility of stock price. In this paper GARCH model is used to analyze the volatility of web news events and public attitudes by the data coming from typical news events in famous web. The results show that the volatility of web news events and public attitudes are suitable to GARCH model by some adjusting and test of parameters.
Nonsurgical orthodontic treatment for an adult with skeletal open bite, class III malocclusion and posterior crossbite: A case report  [PDF]
Yongming Li, Jiaqiang Liu, Yin Ding
Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.33042
Abstract:

Class III malocclusion associated with skeletal anterior open bite pattern in adults can be a challenging orthodontic problem, especially for the nonsurgical treatment. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical correction. Although correction with surgery may be the most effective and stable way, many patients refused surgical treatment plan because of the costs and traumas it may bring. We reported a nonsurgical orthopedic treatment of 22-year-old male with severe skeletal anterior open bite, dental Class III malocclusion, posterior crossbite and a high mandibular plane angle. The patient refused surgery and extraction. So we formulated a treatment plan consisting of using rapid palatal expansion appliance to expand the maxilla, standard edgewise brackets to align the teeth, Class III elastics to correct the canines, premolars, and molars relationship, reverse curve of the nickel-titanium wire combined with anterior vertical elastics to intrude molars and correct open bite. In this case, without suffering of surgery, the posterior crossbite was ideally corrected, and ideal overjet and overbite relationships and functional occlusion were all achieved. The patient obtained satisfactory occlusal as well as functional and stable results.

Ming Ding, Yaozhong Liu, Qinghua Li
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.94051
Abstract: As a concept and phenomenon with strong interpersonal attributes, social comparison shouldn’t be ignored its role in human interaction. This article outlines the interpersonal impact of social comparison, including pro-social behavior, conspicuous consumption, deception, and schadenfreude etc. According to the summary analysis, the upward comparison will bring more negative effects, and the downward comparison will bring more positive impacts. There have been some studies that have explored the psychological mechanisms of this process. Future research can make more exploration on the application scenes and psychological mechanisms.
The Effect of Drama Types and Brand Familiarity on Brand Attitude in Brand Placement  [PDF]
Ziying Liu, Ding Pan, Ya Xu
American Journal of Industrial and Business Management (AJIBM) , 2019, DOI: 10.4236/ajibm.2019.93033
Abstract:
Recent years, with the popularity of the costume drama, brand placement began to appear in the costume drama, such as “vip.com” in drama “Fighter of the Destiny”, and “Unifon” in the drama “Princess Agents”. This phenomenon is very controversial while attracting eyeballs. The large amount of audience can bring exposure to the brand, but many views complain about its rigid, and reducing the brand attitude. Based on the above phenomena, this article builds up a theoretical model including drama types, brand familiarity and consumers’ attitude toward implanted brand. We validate it through two empirical studies, and the results show that, for high-familiar brands, placement into modern dramas will result in more active brand attitudes than places into costume dramas; for low-familiar brands, there is no significant difference between the two. The research results enrich the existing theories of advertising implants. Besides, it also provides references for the exposure of brands in different brand cycles in television programs, in order to obtain the best publicity and economic benefits.
