The design of radar waveforms needs to deal with ambiguity resolution both in range and Doppler. Particularly, the waveforms of Pulse Doppler (PD) radars using low pulse repetition frequency(PRF) waveforms are unambiguous in range but ambiguous in Doppler. To solve the problem, the existing detection algorithms are mostly based on the Chinese Remainder Theorem (CRT), but these algorithms do not have...
AGV path planning problems play an extremely important role in navigations of AGV. Intelligence algorithms provide an effective way to solve such complicated problems. Artificial fish swarm algorithm (AFSA) is a newly proposed promising swarm intelligence optimization algorithm, yet there still exist some disadvantages of it, such as low optimization precision and convergence rate. Aiming at these...
MapReduce is a popular programming model widely used in distributed systems. With regard to large-scale applications, e.g. home energy management in a city, online social community etc., load-balancing becomes critical affecting the performance of distributed computing. Present proposed load-balancing approaches in MapReduce aim at optimizing task execution time, whereas disk space is not considered...
It is well known that the application of Spatial Information Service has a problem of computation intensive. In traditional solution, it is almost impossible to estimate the computing resources of the application and thus either waste or shortage of resources will appear at last. Aimed at it, this paper combines the cloud computing features and presents an algorithm called PSA (Prediction Scheduling...
Location-Based Service (LBS) has become more and more important with the rapid development of mobile internet, it as an information service mainly make use of geographic position of mobile phone to provide accurate services for consumers. LBS involves a mass of longitude-latitude data and mainly involves three problems: Point Query, Range Query, and K-Nearest Neighbors. The object of this paper is...
According to the distribution network with wind power formulated offline island plan and implementation with online island search. In the formulation of offline island plan only to ensure that important load power supply, alternative power supply path; when online search according to the real-time output power of wind turbines , under the premise of the power constraints, with the new online search...
To save energy, solar vehicle have come into being. Therefore, the study of photovoltaic maximum power point tracking is necessary. Traditional photovoltaic maximum power point tracking (MPPT) algorithm such as constant voltage algorithm can not track the maximum power point quickly and accurately. Operation voltage can not be adjusted rapidly with environmental changes when using conductance adding...
Extensible Markup Language (XML) is fast emerging as the dominant standard for representing data on the Internet. Faced with growing knowledge management needs, enterprises are increasingly realizing the importance of interlinking critical business information distributed across structured data and XML documents. We bring up an algorithm link a given XML document with relevant structured data.
Apriori algorithm is a classical mining algorithm uses the association rules. After analyzing the Apriori algorithm, this algorithm is inefficient due to it scans the database many times. Based on the strategy of accessing to database once, a new improved algorithm founded on the Apriori is put forward in this paper. Experiments show that it can significantly improve computation efficiency, i e reduce...
This paper bring forward based on immune genetic algorithm to solve man on board automated storage and retrieval system optimized problem, immune genetic algorithm remains the characteristic which is not easy to plunge into local optimization and merge into the basic life immune theory, enhance overall searching efficiency, immune genetic algorithm has faster convergence velocity than traditional...
Most of attacks in video digital watermarking are synchronization attacks. They can be classified as temporal and spacial synchronization attacks after characteristics of video digital watermarking are analyzed. Then synchronization robustness can be divided into inter-frame robustness and intra-frame robustness according to classifications of synchronization attacks in video digital watermarking,...
In this paper a Hopfield neural network (HNN) based parallel algorithm is presented for predicting the secondary structure of ribonucleic acids (RNA). The HNN here is used to find the near-maximum independent set of an adjacent graph made of RNA base pairs and then compute the stable secondary structure of RNA. We modified the motion equation proposed in paper to reflect more biological essence of...
