In order to enhance prediction precision of online public opinion, it put forward a kind of online public opinion prediction model (PSR-SVR) with the combination of chaos theory and support vector regression. First of all, the original data of online public opinion were obtained throughout topic segmentation, hotspot extraction, and data aggregate....

In order to effectively solve the problems of global discrete grid in spatial data management and operations, a novel equal area quad-tree global discrete grid subdivision model based on latitude and longitude lines is proposed in this paper. Coding rules of grid cells, and geometric distortion calculation and analysis of the grid model are also gi...
Article
Recently, scheduling algorithm which is related to computing tasks and communication transactions is widely studied. In multi-core systems, adopting certain scheduling algorithm to execute schedule can decrease scheduling length effectively after eliminating intra-iteration dependency of the computing tasks. In this case, regulating execution order...

Spectrum allocation is one of the key issues to improve spectrum efficiency and has become the hot topic in the research of cognitive wireless network. This paper discusses the real-time feature and efficiency of dynamic spectrum allocation and presents a new spectrum allocation algorithm based on the master-slave parallel immune optimization model...
Article
Mineral resource prediction is the basis for many spatial operations in digital mine. Thus, there is a growing interest in constructing effective prediction algorithm, both in applications and in science. In this study, a new nonlinear combination forecasting algorithm based on adaptive neural network, support vector machine and relevance vector ma...
Article
After a detailed analysis of the characteristics of mixed traffic flow, the methods of Cellular Automata theory and rule description are used to build the pedestrian model, motor vehicle model and non-motor vehicle model. And then, the avoidance strategy is provided for motor vehicle as well as non-motor vehicle to avoid pedestrian. Finally, the si...

Zero knowledge proof system is an important branch of cryptography and computational complexity theory which has received concern since it was first conceived. Among them, non-interactive zero-knowledge proof system containing only one message from the prover to the verifier has been widely used in the construction of cryptographic protocols and cr...
Article
On the basis of an in-depth analysis about the characteristics of the commonly used 3D entity model, a new integration model based on octree and TIN-CSG is put forward for the applications in digital mine. In this model, we use octree data structure to represent the underground entities and CSG model to represent the overground entities. And then w...

With the increasing demand for the application of future simulation technology and virtual reality, the virtual environment modeling techniques will become increasingly important. Three dimensional terrain is one of important factors of the natural scenes in virtual environment and it is also a significant composition of view system in virtual simu...
Conference Paper
In order to represent 3D spatial entity effectively in geological engineering, a new method of geological information forecast and D reconstruction is put forward based on support vector machine (SVM). Firstly, for the given geological drill hole data, SVM is adopted to forecast ore grade of information unknown areas within the geological sections...
Article
The current urban transportations are mostly mixed traffic, consisting of three kinds of microscopic traffic objects: motor vehicles, non-motor vehicles and pedestrian traffic. In this paper, based on the analysis of traffic characteristics of the above objects, we construct the simulation model for motor vehicles and the cellular automata-based si...

... It also could forecast the tendency of Micro-blog public opinion. SVM model [14,15] is always used to forecast public opinions. The model could cluster the text, extract the hotspots, aggregate the data and implement other pretreatments of the network data, all of these built the forecast model. ...
... In order to reduce cross tier and co-tier interferences in femtocells a clustered approach for resource allocation is adopted in [29]. The [30] compares DSA serial algorithms with master slave parallel immune optimization analytically and with the help of simulations. The authors in [31] provides channel allocation using the colour graph theory which improves utilization of resources with fairness. ...
... A simulação de sistemas de transporte pode ser classificada de acordo com o seu nível de observação dos componentes em três categorias: microscópica [Klügl and Rindsfüser 2007, Usher et al. 2010, Kretz et al. 2011, Xiaobei et al. 2009, Pan et al. 2010, Ma et al. 2008, Ma and Yang 2009, Gao et al. 2009], macroscópica [Xue et al. 2009] A simulação microscópicaé baseada na descrição de movimento de cada componente do fluxo de tráfego, onde cada qual possui um comportamento próprio definido em função do ambiente e de outros componentes do sistema. Para a simulação de veículos, um dos modelos mais popularesé o Car-Following [Huixin andWenhong 2010, Wang et al. 2009], para a simulação de diversas faixas de rolagem em rodovias, por exemplo, onde o comportamento do carroé determinado pelo do veículo imediatamente a sua frente, e cada qual possui informações como aceleração, frenagem e perfil de tomada de decisão próprios. ...
