To fulfill the requirements of complex analyzing of drilling analysis system, aim at the inability of analysis power which exists in traditional information system by database technology, a data-warehouse-based OLAP system has been analyzed and studied within this paper. In accordance with the characteristics of users (which are wild spread at international(More)
For the sake of complex analysis requirements of drilling fluid analysis system, this paper proposes a multidimensional data model and implement the solution of data mart due to the analyzing weaknesses of conventional information system. Since the database system is only applied to undertake the daily manipulating application of raw data, and supports(More)
This paper discusses the single-machine rescheduling problem with efficiency and stability as criteria, where more than one disruption arises in large-scale dynamic circumstances. Partial rescheduling (PR) strategy is adopted after each disruption and a rolling mechanism is driven by events in response to disruptions. Two kinds of objective functions are(More)
A hybrid decomposition method for molecular dynamics simulations was presented, using simultaneously spatial decomposition and force decomposition to fit the architecture of a cluster of symmetric multi-processor (SMP) nodes. The method distributes particles between nodes based on the spatial decomposition strategy to reduce inter-node communication costs.(More)
For firms, entering industrial cluster means obtaining more opportunities for tacit knowledge transfer and informal communication, while forming strategic alliances can get a wider range of technical cooperation and strategic resources. Using innovation networks in the communication equipment industry of China, based on the impact of network density on(More)
This paper investigates the problem of H∞ synchronizations of multi-agent system with random time-delay. It is assumed that the topology of the system is fixed directed and connected. Considering that there are random communication time delays between the agents and additive perturbations, a consensus protocol is forwarded based on the consistence(More)
High-resolution satellite remote sensing brings new ideas to urban traffic information collection, which is a good source of traffic flow data. According to the characteristics of shadow area in remote sensing image, this paper studies the technology and the key method of the vehicle information extraction of the shaded area from high-resolution remote(More)
The diversity and complexity of sediment particle images, has become a constraint major bottleneck problem of establishing the river sediment image segmentation, using sediment particle images with similar particle images in other areas can take advantage of same-sex classes of image processing to propose a morphology-based Otsu binarization algorithm, the(More)
As many parameters change frequently in network, the robustness is particularly important for a congestion control system. A new Fractional Order Proportional Integral (FOPI) controller is proposed based on the TCP/AQM model, which has better control performance and stronger robustness. The simulation results show the advantages of the FOPI algorithm(More)
