Management of overflows caused by stochastic traffic arrivals is one of most important consideration for traffic signal control of isolated intersection because overflows of one cycle can results in not only extra delay in following cycles but also blocking of upstream intersections. Although the stochastic arrivals problem has been studied either by simulation based methods or analytical models,...
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...
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...
Based on the research on the related techniques, English teaching platform under network environment based on J2EE is proposed in this paper. The overall system architecture is presented and function of each module is analyzed in detail. In order to improve the access efficiency of database, we use the database connection pool technology. Under environment of network education, the teaching resources...
A district of some city of Shandong Province is taken as an example to discuss the key technology of 3D digital community modeling. We investigate the characteristics of spatial data, spatial data model classification and research status. We also give process of 3D visualization. At last, 3DMax software is used to set up a residential building model in some city, and OpenGL software is used for visualization...
The traditional frame differential method in football detection is still not satisfactory, so the traditional frame differential method is improved. In this paper, we use the Gaussian image pyramid in down sample processing. The processing pixel points are a quarter of the original, so that system has a higher speed. We propose a kind of football detection scheme based on automatic threshold segmentation...
With the cloud computing development, elastic scaling capability is an important factor to ensure the quality of cloud services. In this paper, the author designed resource requirement model about web system based on neural network under the certain quality of service on cloud platforms. According to the model, the method and mechanism for elastic scaling is realized by BP algorithm on cloud platforms.
Due to the application requirement of single source tracking in dynamic background, it is difficult to get accurate pedestrian target detection. Through comparing performance quality of pedestrian describing operator between CENTRIST and HOG, we adopt CENTRIST feature extraction to combine with SVM off-line classifier and to train off-line model for target detection. Furthermore, we propose the importance...
This paper takes advantage of AHP-PCA so as to make a primary selection, which contains the datas of water quality, sediment and biological index. To analyze the eco-environmental quality driving force weight of ecological potential risk index has been confirmed, the pollutants of heavy metals and petroleum hydrocarbon in sediment turns viewed as the principle potential ecological risk evaluated factors...
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 this paper, the quadratic regression general combinational design was used to ensure the color quality of fresh potato after hot air drying and to optimize of hot air drying process based on a single factor test. Considering the temperature of hot air, the velocity of wind and he length of chop, the brightness degree value L, red degree value a, yellow degree value b and drying time t of the product...
"Internet +" era for college students to a broader entrepreneurial market, in the context of the O2O model has a strong adaptability, can effectively help for college students. Analysis of operation status indicators of this university campus business platform based on O2O mode, from platform construction, operation management, profit model, marketing strategy, payment and logistics has...
Credit risk evaluation is the basic work of commercial bank's credit risk management, which goal is to analyze the credit risk of the bank. Support vector machines ensemble has been proposed to improve classification performance recently. However, currently used fusion strategies do not evaluate the importance degree of the output of individual component SVM classifier when combining the component...
The comprehensive quality of the accounting profession not only shows the enterprise's ability to work, but also shows the social value. Based on this, the objective evaluation of the accounting professionals is particularly important. There are many factors restricting the comprehensive quality of accounting professionals, in order to eliminate useless factors or other factors which have high correlation,...
With the development of technologies of cloud computing and distributed cluster, the concept of big data was extended widely and deeply in volume and value, and data mining that plays an important role in exploring big data was attracted unprecedented attention in recent years. Traditional data mining algorithms is incapable to deal with massive dataset. MapReduce has been successfully applied in...
China's traditional sports has a long history, profound content, is the main content of college martial arts and national traditional sports professional teaching. Along with the arrival of the era of network information, martial arts and traditional ethnic sports teaching also break through the limitations of previous "words and deeds", and computer information technology combined martial...
By adding a binary relation and a number of assessment factors into an approximation space, a rough assess-ment system was obtained. Based on the assessment factors, the concepts of the weight and comprehensive weight were defined, which leaded to the comprehensive lower value of an edge set, so, a path could be optimized by making use of the comprehensive lower value, also an algorithm called path...
The greenhouse is designed to recreate an environment wherein the temperature, humidity and light are monitored and adjusted to optimize the conditions of plant cultivation. Based on monitoring platform of crop growth environment and information management need of the control agriculture greenhouse, an precision agriculture greenhouse based on IoT and fuzzy was designed. The system uses a fuzzy control...
Data warehouse is structured data environment of decision support system and online analytical processing data source, The data warehouse's concept and its characteristic are expatiated. Describes the characteristics and design method of data model in the data warehouse, then it introduce the decision support system based on data warehouse, taking the establishment of sale decision analysis system...
With the development of Internet of Things (IOT), the idea of intelligent college becomes a hot topic. However, there are few researches for intelligent college design. An Intelligent College Network Design (ICNS) is proposed. ICNS aims to utilize IOT and cloud computing for intelligent college construction. It contains four sub-systems for different computing and monitoring requirements. Tests show...
