Interaction Mechanism and Strategy of Brand Relationship and Brand Extension  [PDF]
He Liu, Lili Fan
Open Journal of Business and Management (OJBM) , 2013, DOI: 10.4236/ojbm.2013.13008
Abstract: As new products are generally difficult to be accepted by consumers, and the cost of initial market introduction is high, enterprises often choose to do market extension of an existing brand. Simultaneously, a successful brand extension can enhance the reputation of the original brand, and expand the brand value. But how can enterprise take a good brand extension? Through establishment of a dynamic model of brand extension under the brand relationship context, investigating the interaction mechanism between brand relationship and extension, and base on that, we developed a strategy model of interaction and improvement of brand relationship and brand extension.
Performance Evaluation of a New Type of Polymer Profile Control Agent  [PDF]
Qingwang Liu, Zhe Zhang, Zhenzhong Fan, Zhenzhong Fan, Jigang Wang
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.65040
Abstract: The low-permeability oil and gas resources of our country are quite common and abundant. Their reserve has accounted for one-fifth of total oil reserves of our country, and their yield has constituted the important part of national petroleum annual yield, but its development is very difficult. Polymer gel technology is a technical method of improving sweep efficiency in recent years which substantially increases the viscosity of the polymer solution by adding a crosslinking agent to the polymer produced by intramolecular or intermolecular crosslinking.

Practice has proved that we can obtain a significant effect by a variety of ways practice teaching methods such as formation of interest groups, the use of race to promote education, race and promote, to point to an area of practice teaching model, learning by doing.

Research on Motion Attention Fusion Model-Based Video Target Detection and Extraction of Global Motion Scene  [PDF]
Long Liu, Boyang Fan, Jing Zhao
Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.43B006
Abstract:

For target detection algorithm under global motion scene, this paper suggests a target detection algorithm based on motion attention fusion model. Firstly, the motion vector field is pre-processed by accumulation and median filter; Then, according to the temporal and spatial character of motion vector, the attention fusion model is defined, which is used to detect moving target; Lastly, the edge of video moving target is made exactly by morphologic operation and edge tracking algorithm. The experimental results of different global motion video sequences show the proposed algorithm has a better veracity and speedup than other algorithm.

Error Searching System with Keyword Extraction and Keyword Fuzzy Matching  [PDF]
Fan Yang, Zhenghong Dong, Lihao Liu
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2017, DOI: 10.4236/ijcns.2017.105B022
Abstract:
This paper has proposed an error searching method to search the solutions of errors that occurred in the unified commanding platform mix-deployed software (UCPMD). Because those errors belong to different stages or may be happened in different services, applications, IP ports, system software, or different versions of software, and those errors are also can be classified into different types. It is necessary to locate accurate reason that cause an error as well as find out its solution. The proposed error searching system applies Chinese keyword extraction and Chinese fuzzy matching between keywords, which considers the processed keywords as the index to find out the solutions of errors. Besides, the error searching system had made correspondence among errors, reasons, and solutions, and put them to different categories in terms of their characteristics, such that it is easy to manage, search, and use. Among others, we have added specialized thesaurus as the index of keywords, which enriches and completes the searching results. Because of the proposed error searching system evolves keyword extraction and keyword fuzzy matching technologies; it is more accurate to find out user-interested solutions.

Optimal Deployment with Self-Healing Movement Algo-rithm for Particular Region in Wireless Sensor Network  [PDF]
Fan ZHU, Hongli LIU, Shugang LIU, Jie ZHAN
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.13028
Abstract: Optimizing deployment of sensors with self-healing ability is an efficient way to solve the problems of cov-erage, connectivity and the dead nodes in WSNs. This work discusses the particular relationship between the monitoring range and the communication range, and proposes an optimal deployment with self-healing movement algorithm for closed or semi-closed area with irregular shape, which can not only satisfy both coverage and connectivity by using as few nodes as possible, but also compensate the failure of nodes by mobility in WSNs. We compute the maximum efficient range of several neighbor sensors based on the dif-ferent relationships between monitoring range and communication range with consideration of the complex boundary or obstacles in the region, and combine it with the Euclidean Minimum Spanning Tree (EMST) algorithm to ensure the coverage and communication of Region of Interest (ROI). Besides, we calculate the location of dead nodes by Geometry Algorithm, and move the higher priority nodes to replace them by an-other Improved Virtual Force Algorithm (IVFA). Eventually, simulation results based-on MATLAB are presented, which do show that this optimal deployment with self-healing movement algorithm can ensure the coverage and communication of an entire region by requiring the least number of nodes and effectively compensate the loss of the networks.
Sodium resonance lidar observations during 2001 Leonid meteor shower over Wuhan
Jinbo Liu,Fan Yi
Chinese Science Bulletin , 2004, DOI: 10.1007/BF03182816
Abstract: Here is the first report on the observation of meteor ablation trails with lidar in China. Four long-lived Na ablation trails were observed during the 18/19 Nov. 2001 Leonid meteor shower with a sodium resonance lidar over Wuhan. The mean altitude of the 4 trails is 97.95 km, consistent with Leonid high entry velocity (~72 km/s). The peak density averages about 3380±3633 cm 3, and the abundance is (2.33 ±1.49) ×108 cm 2, both of which are higher than those previously observed for sporadic meteor trails. The RMS width is 359 m and the meteor’s age is 81 min, indicating that they are long duration meteor trails. These observation results are quite different from those of sporadic meteor trails, but comparable to the 1998 and 1999 Leonid report. Five night observations from 17 Nov. to 23 Nov. suggest that the 2001 Leonid meteor shower does not have a significant impact on the abundance of the background Na layer.
