The number of small-and mid-cap companies increases in recent decades due to the change on technologies. A considerable number of information systems are thus built for efficient production and management. As a result, a large number of operations and data are generated. The internal IT unit must have the ability to process the large amount of data, provide different services for each kinds of users,...
Big data as another revolution of information technology is happening and has a huge impact on many fields of the society. In the military communication field, massive and multi-source data with explosive growth of operational command, operation and maintenance, meteorological environment provides the information source for data analysis in "information war" era. In order to improve the...
Testbed plays an invaluable role in facilitating research and development of wireless sensor networks (WSNs). A WSN testbed involves three fundamental tasks, which are reprogramming the WSN nodes, debugging the WSN applications and observing the status of the WSN nodes. In this paper, we propose a testbed with parallel reprogramming and multi-channel debugging capabilities (PARED) to meet the challenge...
With the interdependencies that exist between data in a scientific processing pipeline, the ability to track the provenance of the scientific process through multiple stages is necessary to determining the usability of the resulting data product. In this paper, we study the capture of provenance from an existing NASA instrument ingest pipeline. Since instrumenting the scientific code for a production...
First, this paper introduces the four tiers architecture of Team center, the integration framework for CAD/CAPP/PDM, and gives the integrated method of each system based on Team center. Second, this paper concretely analyzes the technological design process based on the PDM. Then based on a bearing company's normalization project, we introduce the enterprise's business data model, the establishment...
A typical cloud platform provides capability of scalability, elasticity and fault tolerance. Moreover, it is designed to deal with high volumes of data on nearly unlimited number of machines. On-Line Analytical Processing (OLAP), a kernel part of modern decision support systems, allows interactive analysis of multidimensional data of varied granularity. A combination of the Cloud Computing and OLAP...
The ultimate goal of both game developers and network engineers is to provide a satisfactory quality of experience (QoE) for players. Most past works resort the subjective approaches to assess QoE which have serious limitations. But because of the interdependency of the quality metrics on game playability and the involvement of many players' subjective factors, defining an objective evaluation methodology...
To meet the requirements of some intelligent vehicle monitoring system, the software integrates Global Position System (GPS), Geographic Information System (GIS) and Global System for Mobile communications (GSM) in the whole. The structure, network topology, functions, main technical features and their implementation principles of the system are introduced. Then hardware design of the vehicle terminal...
Data acquisition technology based on long distance wireless network is one of the hot research problems of data acquisition technology at the present time. This paper applies data acquisition technology based on GPRS to automatic collection of noise data, designs encapsulation format of data. Data collection terminal accesses to network through GPRS to upload noise data to database of remote server...
In recent years, the travel time predictions have become a popular research topic. In this paper, we present a new algorithm of the travel time predictions based on the idea of using the shared traveler's positions to collect traffic conditions. Several experiments show that our algorithm has a broader applied area than existing algorithms and can provide real-time and the accurate predictions for...
Design patterns provide an efficient way to create more flexible, elegant and ultimately reusable object-oriented software. Thus their correct application in a system's design will significantly influence its reusability, flexibility, extensibility and maintainability. In this paper, we explain how design patterns are selected and implemented in a Java enterprise application naming Piloting management...
For the management of urban land resources and real estate development, periodic updating of information is crucial, particularly in some cities where exist serious problems of land resources shortage. However, collecting information related real estate development through full ground surveys would be very costly and time-consuming. On the basis of related technologies of Mobile Geographic Information...
SOA has become more and more popular, but fault tolerance is not fully supported in most existing SOA frameworks and solutions provided by various major software companies. SOA implementations with large number of users, services, or traffic, maintaining the necessary performance levels of applications integrated using an ESB presents a substantial challenge, both to the architects who design the...
