Ultrasound image segmentation has strong pertinence, all kinds of algorithms are usually based on a particular area, specific imaging mode, and interested particular object. These problems make the ultrasonic image segmentation has no unified standard and common rules. Based on characteristics of C-V model and graph cut model, C-V model is discretized and combined with graph cut model to form new...
In recent years, the researches on primitive exponent of two-colored digraph have gained some achievements. This paper studies a kind of two-colored digraph, matrix theory and graph theory are used to research a two-colored digraph, which indicates color-patch map has only two circles, respectively n-cycle and (mn-1)-cycle, and these two cycles only have two public arcs. It gives the primitive condition...
This paper proposes a mathematical model of residential community opening up strategy for smart city. The model is an improved U. S. Bureau of Public Roads (BPR) model which additional considers the factors: pedestrian, bicycle and non-motorized vehicle. The model evaluates the traffic time after communities' opening up. Finally, this paper gives some instances and analysis of four different kind...
According to the possible question of the defects behind shield tunnel s and its consequences in the water-soaked sand and pebble stratum, Chinese first full-sized test platform of shield tunnel s with Ground Penetrating Radar (GPR) detection were already established. On the basis of the difference of electrical parameters between segments, grouting layer and surrounding rock, the platform has been...
Constant expansion of construction land leads to occupation of massive cultivated land and increasingly prominent contradiction between human and land. Scientific prediction and reasonable planning utilization of construction land have great importance. In the paper, statistical data of Kunming from 2002 to 2011 is selected. Influence factors undergo correlation analysis and grey correlation degree...
By means of the regional differentiation method and on the basis of spatial measurement, this paper conducts the qualitative and quantitative analysis of land resources of the urban agglomeration in Yunnan with the general regression model of panel data. After utilizing the indexes of land resources and economic development between 2003 and 2012, this paper calculates the coefficient of land resource...
This paper makes use of the big data of urban development via the application of the diversification index and fragmentation index of land use to analyze the urban land use structure of Kunming and evaluate the urban land use efficiency of Kunming based on the indexes of the GDP per unit area of land and population capacity, targeting the existing problems in the urban land use structure of Kunming,...
Port, as the intensive transportation hub and core platform of modern trade and logistics, is connecting two markets at home and abroad. It is the most active market to realize the reconfiguration of global resources, and it is now developing gradually into the most important logistics information center. The construction of the "smart port" of Huizhou Port is to meet the need to advance...
In modern architecture, advanced building automation system is widely used for automatic monitoring and control of all kinds of building systems, but the actual operation data of the building which is stored in the system is not fully utilized. Firstly, this paper analyzed the characteristics of data mining technology and its application in the field of architecture, and then according to the selection...
In the distributed database system, the data is stored in the different nodes of the same network. In order to achieve synchronization update of the database information, problem of data consistency and integrity turns up. Under this background, the data synchronization research on distributed database system is a hot topic. The proposed synchronization mechanism based on ETL and XML is mainly proposed...
In this thesis, jumping out of the traditional data statistic analysis method, the author constructs smart campus data platform and uses Apriori algorithm to make the association analysis on the learning and living data of students in campus in order to excavate their marks, basic information, attendance and states of internet use. In this way, the university can better guide the students to study...
To study and pose an modified discovery method for campus hot topics. The method is to extract word segmentation and keywords from the campus news collected on information big data platform through ICTCLAS word segmentation system, construct the text knowledge representation model based on vector space modal and finally add up the word frequency of headlines to determine k initial clustering centers...
In this paper, established a statistical model of multi level group decision making to study the development status of Tangshan city college students' leisure sports, analyze the basic situation and influence factors of college students participating in leisure sports activities, and put forward the corresponding development countermeasures to solve the existing problems. This paper mainly uses literature...
The motivation of students' learning motivation is the focus of the current campus teachers should pay attention to. With the development of computer technology, the introduction of multimedia technology into the daily teaching process has been very popular, and has been widely used. In accordance with their aptitude, based on this platform, to solve the incentive strategy of intelligent decision...
Along with the pace of China's reform and opening up, rapid economic development, our country the proportion of investment in education is also increasing day by day, tend to improve our country's education and teaching facilities, teachers level increased year by year, especially English teaching ability and quality improvement is particularly outstanding. In recent years, the education system of...
With the development of modern network technology and the increasing information, society begins to gradually into the era of big data. Under the environment of Big data, the campuses how to implement the management strategy with the help of big data, and how to strengthen the utilization of big data to make construction of "digital campus" and "smart campus" become the focus of...
The evaluation of teaching quality is a typical problem of uncertainty. In order to scientifically and reasonably test education quality in universities with teaching evaluation index system of current school, according to supervising experts' knowledge and experience in teaching field, this paper puts forward design scheme in teaching quality evaluation system based on FAHP. First, this paper applies...
Based on the big data of migrant population and the basic data of population census, this paper applies the method of weighted average for modulus coefficient to conduct calculation and analysis on the educational level of the migrant population in Lincang and the differences in the level among the counties. According to the research result based on big data analysis, the educational level of the...
In accordance with the model of mobile learning based on Android platform, from three aspects of the server, the network environment and the client, we investigate the server deployment design, communication protocol selection, voice recording and playback and other issues. Then interactive English grammar learning system is established. In the system implementation phase, the data transmission based...
Dynamic symbolic execution is an important automated testing technique. Firstly, we introduce the traditional symbolic execution and dynamic symbolic execution technology, and then review the research status of Python application testing with dynamic symbolic execution technology. Then we compare and analyze the dynamic symbolic execution tools with the existing Python programs and Architectures,...
