With complex pathogenesis, Chronic Obstructive Pulmonary Disease (COPD) is difficult to treat. Traditional Chinese Medicine (TCM) showed obvious effect in treating COPD. However, invaluable TCM experience lacks of systematic summarization and study. Association rule is used to discover the relationships among data items in a large amount of data. Because of clear and useful results, association rule...
Ontologies are the knowledge repositories that enable meaningful inter-agent communication in semantic web frameworks. To support the huge number of services that will be developed in the semantic web, ontologies are growing larger and larger to accommodate as much knowledge as possible. Accordingly, the process of maintenance, reuse, reasoning and integration of ontology becomes very computationally...
Enterprises today rely on workflow more and more to accomplish business goals. A well designed process can contribute to better business operation and working efficiency. In practice, however, most organizations have no efficient workflow, either there is not at all from the very beginning, or lack domain experts who equip with the comprehensive landscape about the business. In order to conduct business...
Dynamic invocation has always been a hot issue in Web services in order to take full advantage of the flexibility of services computing. One key underlying enabling technology is a self-descriptive contact between the service consumer and provider. In the SOAP-based environment, WSDL has been proven a successful description language which is widely accepted. But for many years, we cannot get the equivalent...
Any effective CRM will be based on solid customer segmentation. This paper puts forward a new segmentation measure involving profitability, profit growth rate and relationship reliability. This paper also describes in detail how to calculate these dimensions.
With the resurgence of virtualization technologies and the development of multi-core technologies, the combination of the two becomes a trend. Therefore, inter-VM communication becomes a key part in how to improve the performance of virtual machines (VMs) basing on multi-core platform. In this paper, we first analyze the characteristics of multi-core tasks and the properties of virtual machine environment,...
Project risk element transmission theory puts forward a new idea of research on project risk management. This paper combined with state transfer diagram, analysed enterprise multi-project management, made concrete exposition on the thought of project chain with different risk element kinds. A tetrahedral structure model of enterprise project chain risk element transmission and controlling mechanism...
The layout problem of weighted circles is a class of layout optimization problems with behavior constraints. Aiming at this NP-hard problem, this paper puts forward a fast heuristic ant colony approach(FHACA). This approach obtains the heuristic information from weighted matrix and uses it to construct the better ants and design parameters of ant colony optimization. The layout schemes of some ants...
In this paper, we propose a channel adaptive multi-sources transmission (CA-MST) scheme in wireless sensor networks (WSNs). To minimize the frame-error-ratio (FER), the proposed scheme switch between the distributed space-time block code (D-STBC) scheme and cooperative network-assisted diversity multiple access (C-NDMA) scheme according to the channel quality. Under the given system model, we analyze...
The accuracy of magnitude prediction is crucial for steganalysis schemes that use high order statistics in wavelet domain. The steganalysis performance can be improved by avoiding large prediction errors. In this paper, a statistical steganalysis algorithm is proposed based on predictability analysis and magnitude prediction of wavelet coefficients, which improves the steganalysis sensitivity by identifying...
We propose a scheme of multiple 16QAM signals generation at 40 Gbit/s using a novel transmitter. The scheme is based on a dual-parallel Mach-Zehnder modulator (DPMZM) and a following phase modulator (PM). We demonstrate the proposed transmitter by VPI simulation and three types of 16QAM signals are obtained, which shows the feasibility of the transmitter. In order to further investigate the transmission...
In this paper, we evaluate the performance of anti-collision algorithm of RFID system. We research dynamic framed slotted algorithm (DFSA) based on EPC Gen2 protocol based on this we studied a kind of framed time slot improvement algorithm (EDFSA) this algorithm absorb the merit of dynamic framed time slot algorithm , this algorithm solve the problem. When huge number of label quantity need to be...
Motion estimation is being utilized more and more in video post-production and display for a wide range of applications. These applications require accurate motion trajectories at low computational cost. This paper presents a novel motion estimation algorithm that combines the accuracy of MAP estimation with the speed of hierarchical block-matching algorithm (BMA). This MAP estimation uses three consecutive...
In semantic Web, ontology mapping is the basis of the interoperation of heterogeneous ontologies. Ontologies are usually distributed and heterogeneous and thus it is necessary to find the mapping between them before processing across them. The current ontology mapping methods merely use massive Web pages in the Internet and they are unpractical to subsequent interoperation and integration of heterogeneous...
Maximizing the operational lifetime of a sensor network is a critical problem in practice. Many prior works define the network's lifetime as the time before the first sensor in the network runs out of energy. However, when one sensor dies, the rest of the network can still work, as long as useful data generated by other sensors can reach the sink. More appropriately, we should maximize the lifetime...
Mining of confident patterns from the datasets with skewed support distributions is a very important problem in the pattern discovery field. A hyperclique pattern is presented as a new type of association pattern for mining such datasets, in which items are highly affiliated with each other. The maximal hyperclique pattern is a more compact representation of a group of hyperclique patterns. In this...
Digital works are considered as research focus in most existing digital copyright protection schemes. But the customers not the digital works have active aggressiveness. That is to say the customers are the fundamental reason of copyright protection problem. So customers should be monitored moreover. The existing identity authentication could verify the legitimacy of customers. But it can not distinguish...
A micro-mixer for mixing digital droplets fabricated on 128degY cut X LiNbO3 is reported, which is composed of one interdigital transducers and one reflector for generating unidirectional acoustic field. After a RF signal amplified by a power amplifier was added on an interdigital transducer, surface acoustic wave was excided by the interdigital transducer, and was conversed into longitudinal acoustic...
With the development of GIS (geography information system), gradually GIS technic is applied in more and more fields from decision-making of government to every aspect of modern society. On the other hand software of today is becoming larger and more complex, component technic has played a very important part in development of software. Especially when you develop B/S (browser/server) software, you...
A novel personalized instructing recommendation system (PIRS) is designed for Web-based learning. This system recognizes different patterns of learning style and Web using habits through testing the learning styles of students and mining their Web browsing logs. Firstly, it processes the sparse data by item-based top-N recommendation algorithm in the course of testing the learning styles. Then it...
