With the continuous development of Vehicular Ad-hoc Network and Cloud Computing, the concept of Autonomous Vehicular Cloud has emerged. In the highway scenario, Autonomous Vehicular Cloud has high dynamic and mobility and the node resources can be used for a short time, which brings great challenges to the use of resources. In order to improve the efficiency of computing resources, the introduction...
Large-scale complex avionics software system developed by multiple teams may lead to inconsistency issues of different architectures and various standards. The generic open software architecture for avionics system similar to Future Airborne Capability Environment (FACE) is therefore proposed. In this architecture, the portability of components is allowed through standardized interfaces between components...
With the deployment of ultra-dense HetNets, the inter-cell resource allocation requires new network solutions to handle differentiated user demands, while software defined network (SDN) has emerged as a solution to it for imbalanced user needs, as well as enabling efficient resource utilization and QoE. Under such motivations, we employ a QoE assessment model over SDN to analyze the impact factors...
In a component-based system, both the reliability and topological location of each component contribute to the software architecture reliability. Due to the limited resources, it is very crucial to identify the key set of components such that we will be able to devote our resources to those components in order to improve the system availability and reliability most effectively. Unfortunately, few...
In the beamformers of modern digital ultrasound imaging system, to avoid storing amount of precalculated parameters, real time delay calculation has to be used. This paper describes the design and implementation of a calculator of beamforming delay parameters, which based on pipelined Coordinate Rotation Digital Computer (CORDIC) architecture and 2-level carry look ahead (CLA) adder. High computational...
A novel coordinated scheduling algorithm for OFDM-based systems in multi-cell scenario is proposed in this paper. The studied algorithm based on the utility function is general for the downlink of networks. The algorithm coordinates the subcarrier assignment over the BS cluster. We first establish the framework for this inter-cell coordinated optimization problem through utility-based method. The...
As a typical form of Cloud service, Software as a Service(SaaS) has been leading the adoption of Cloud to enable e-Business by the industries. There are growing number of SaaS services which could provide different aspects of capability enabling business to leverage Cloud platform to run and manage business processes, such as customer relationship management, supply chain management, finance and accounting...
With the developing of spatial information and Internet technology, marine management departments begin to design and develop information systems on the basis of GIS technology. It helps government to improve their work efficiency. However different departments use different technologies, different data formats and different work flows, and one department can not access other departments' data or...
Architecture design is an essential phase in software engineering. To effectively re-use pre-verified knowledge is critical for design high-quality architecture. Among several different approaches, architectural patterns are widely investigated as they capture the fundamental structural and behavioral principles of architecture design. Although a lot of patterns have already been defined, the application...
As a macro complex systematic engineering, the Digital Ocean project is an ongoing task in china. The mission of the Digital Ocean is to build an interactive network information system based on a three-dimensional globe. The Digital Ocean can help provide integrated information on historical, current and future states of ocean and coastal zone. This paper addresses the architecture of Digital Ocean,...
