In order to process real-time phased array ultrasound imaging, to improve imaging resolution, and achieve on-line defect detection, total focusing method (TFM) imaging algorithm is used for the complete data, thrust reversers the focus and algorithm in different positions, the computational problems of large data can be solved by the FPGA parallel algorithms. After that, the total focusing method...
Service Composition provides a flexible framework for new service construction by integrating atomic services developed independently. Algorithms are needed to select atomic service and service instances with various QoS levels according to some application-dependent performance requirements. Our objective of service selection is to maximize a QoS function under the end-to-end QoS constraints, as...
In order to improve the IT services and make them more accessible, a lot of service supporting platforms are adopted the framework of ITIL. The service desks as the connector between the customers and platforms play a very essential role in the process of Service Support. Incident management is started from the service desh directly or indirectly. Incident management can help the customers to solve...
With the maturity of SO A and rapid development of Internet, more and more enterprises will open their resources to public using SOAP-based web service. Because SOAP protocol is based on XML-format data, parsing and generating SOAP message spends much time and consumes a vast of resources. Moreover, complex network environment poses challenge of extreme concurrent, dynamic contents, continuous high...
In this paper, a service routing method is proposed to support the pervasive E-commerce. To offer flexible routing control across multiple service domains, a customized route computation should be offered. In our method, a QoS-routing protocol is designed to select end-to-end paths that satisfy user requirements. And global QoS is guaranteed by the runtime QoS monitoring and dynamic adjustment.
With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster,...
In this paper, a E-Commerce service composition platform is proposed to support the pervasive E-commerce. The platform consists of an Orchestration Component and several Atomic Service Components. The platform is based on atomic reusable and sharable service components. And it employs efficient P2P interaction between two components. In our method, global QoS is guaranteed by the runtime QoS monitoring...
Mashups is an emerging technology that enables users to create a new application based on a composition of contents retrieved from external services or applications. Mashup Platform allows non-programmer end-users to mash-up information sources and services to meet their information needs. However, with the increasing number of services, information sources and complex operations like filtering and...
Service composition is becoming a hot research point in recent years, especially in distributed peer-to-peer (P2P) network. However, how to guarantee the high-quality composition service performance becomes the key technology and difficulty in P2P network, which draws lots of attention in computer research field. According to the characteristics of distributed network, an adaptive service composition...
Analyzing the network coding and its application in mobile P2P network, a novel network coding dynamic node selection method in mobile peer-to-peer (P2P) network is proposed, which the hierarchical network structure divides the nodes into super node (SN) and ordinary node (ON). Considering the heterogeneous and dynamic characteristics, part coding node (CN) selection program is adopted, which overcomes...
The problem, such as low efficiency in discovering resource, high usage of network bandwidth, is caused by the frequent mobility of nodes in peer-to-peer network. A self-organizing routing model in mobile peer-to-peer base on dynamic region management is proposed by dint of our improved Meridian model. According to the mobility strength of nodes and introduction of dynamic management, the proposed...
With the popularity of Web2.0, web has become to be a application programming platform where third parties can create new applications (mash-ups) mixing the functionality offered by others. Now this trend has extended to the domain of mobile networks. The combination of mashup and mobile networks would make the mashup more powerful and provide additional user value. This paper explores how to realize...

A novel algorithm for the direction of arrival (DOA) estimation based on the fractional Fourier transform (FRFT) is proposed. Multi-component LFM signals are filtered and demodulated into a number of stationary single frequency signals. Then the direction estimation of LFM signals can be achieved by combining with the traditional MUSIC method in the fractional Fourier (FRF) domain. The statistical...
With the emergence of new business and the change of customers' needs, the traditional OSS gradually can't response to all of these. It cost much to develop a new business, and can't quickly adjust the existing business to meet the change of the market's needs. So how to change this situation? Now, SOA became more and more popular with system designers and integration staff, and BPM breaks the limits...
Low efficiency occurs just because physical topology isn't considered when Mobile Peer-to-Peer (MP2P) constructs overlay network; this paper will propose a novel vector location-based algorithm based on Distributed Hash Tables (DHT) algorithm. Using pole coordinates to divide physical network into different zones, constructing new routing protocol based on the location vector information; thus, nodes...
Service oriented architecture became more and more popular with system designers and integration staff. Enterprise service bus is the basic infrastructure in implementing service oriented architecture. Java business integration specification provides a standard mechanism for enterprise service bus. This paper proposed a Java business integration based solution for service bus platform. It was designed...
Next generation networks (NGN) are the basis of converged IT and telecom services and OSS is a crucial, mission critical area in the Telecommunications domain, in particular in a period of economic recession and heavy cost savings. There is a trend to adopt Service Oriented Architecture (SOA) to rationalize OSS infrastructure in NGN. In this Paper, we present an innovative OSS solution based on SOA...
