The study aims to research the effecting factors of the level of independent innovation ability in China, constructing innovation environment by the grey clustering model and build the national innovation capability evaluation index system, including the innovation input, innovation output and innovation potential of 4 indexes and 17 level two indexes. The related data of 26 countries was collected...
Fine-grained object recognition is more challenging than generic categorization due to the subtle difference between subcategories under the large intra-class pose change and appearance variations. The state-of-the-art fine-grained recognition methods usually utilize part detection or pose alignment to alleviate the pose variation, and then use convolutional neural networks (CNNs) to extract local...
Optical switches are widely considered the most promising candidate to provide ultra-high speed interconnections for future communication and computing systems. Due to the difficulty in implementing an all-optical buffer, optical switches with electronic buffers have been proposed recently. Among these switches, the optical cut-through (OpCut) switch has the capability to achieve low latency and minimize...
The well-known feature transformation model of Fisher linear discriminant analysis (FDA) can be decomposed into an equivalent two-step approach: whitening followed by principal component analysis (PCA) in the whitened space. By proving that whitening is the optimal linear transformation to the Euclidean space in the sense of minimum log-determinant divergence, we propose a transformation model called...
For text-query-based keyword spotting from handwritten Chinese documents, the index is usually organized as a candidate lattice to overcome the ambiguity of character segmentation. Each edge in the lattice denotes a candidate character associated with a candidate class. Character similarity (between character and class) scores are calculated on each edge, and the similarity between a query word and...
A deep study is given to smart grid comprehensive evaluation system. According to the smart grid characteristics and basic properties in China, a smart gird index system is built from the aspects of strongness, reliability, efficiency, economics, environment and interaction. Based on the calculation of Entropy-ANP combined weighting and improvement on two evaluation methods, a new method of comprehensive...
This paper proposes a lattice-based method for keyword spotting in online Chinese handwriting to improve the trade-off between accuracy and speed, and to overcome the out-of-vocabulary (OOV) problem of lexicon-driven approach. Using a character string recognition algorithm, the lattice-based method generates a candidate lattice of N-best list. We observe that search multiple candidate strings reduces...
In the field of software developing, project is almost the most common organizational form. But with the enhancement of software products' complexity and the constant change of customers' demand, the importance of communication in software development projects is increasingly prominent.Based on literature review about communication management and software development life cycle, the paper identified...
Traditional method of storing and querying XML documents is in single processor environment. The system performance deteriorates when the size of XML data sets increased. Parallel processing technology based on multi-processor is proposed in this paper. The key issues such as XML data model, storage model, data placement strategy, paralleling query, indexing etc. are also discussed.
This paper studies the methods and strategies of the network update of the land survey spatial data based on embedded terminal equipment and server and application of multi-level distributed heterogeneous land spatial database.Web services network model has been used to do the design and implementation work of embedded system of land survey data update. The main procedure of spatial data real-time...
Effective power supplying service management is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we analysis the characteristics of power supply enterprises, follow the thought of "Identifying problems - Finding problems - Solving problems", that is identifying problems based on the theory of Gaps model, establishing a service quality evaluating...
Effective customer satisfaction evaluation is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we establish the power customer satisfaction evaluation index system based on previous studies. Then we prove the validity of this method through field investigations by using SAS. Finally, path coefficient analysis is conducted to get key factors to improve...
The vehicle distribution problem has been a NP problem for a long time; it can not reach a most optimized state. Because of the multi-factors that should be considered about the vehicle distribution problem such as the loading capacity, sources , the cargo categories and so on. So it can not to describe it with one or a set of math expressions. This article based on the Genetic Algorithm takes each...
In the context of China economy's booming up and the dominant place in the world shipping market share, the efficiency of container terminals has become an important factor to the interaction between China and the world. The paper uses DEA models and Malmquist TFP approach to measure the efficiency of container terminals in mainland China. Our data, which is from China's port yearbook (2004 ~ 2006),...
In order to ensure the healthy development of distribution center (DC), it is necessary to constitute the evaluation method. This paper deals with establishing the evaluation method of DC by grey reltional analysis (GRA). Firstly, the parameters of the indices system were selected, such as the rationality of location, the efficiency of space utilization and the level of information et al.. Secondly,...
