It's becoming more and more difficult to get enough failure data sample during life test of modern integrated circuit(IC). However traditional reliability assessment methods need a large number of failure data sets. In order to resolve this contradiction, this paper proposed a life prediction method of IC with small sample based on least squares support vector machine (LSSVM). This method can predict...
In this paper we propose an ontology model to describe the domain of searching over multiple data sources (SND). The ultimate goal of the model is to bridge the heterogeneity and to solve the distribution of the multiple networked data sources. Based on the model a query reconstruction algorithm is proposed to translate the initial query into different local queries suitable for individual data sources...
In the era of continuously enlarging mass customization based on customer requirements, a Classification method called MP-NB (i.e. Map Reduce-based Naive Bayes) is proposed to process CRIA(i.e. Customer Requirement Information Acquisition) classifications on large-scale mobile data. It utilizes Hadoop2.X-based system to store CRIA on HDFS. Combination with the standardization theory of CRIA, It utilizes...
In this article, we expanded analysis for the constructing of data convergence protocol through ant colony optimization. First, we introduced the ant colony optimization, the basic structure of wireless sensor network and data gathering process. Secondly, in the experimental simulation part, ACO system model was constructed on this structure based on the structure of wireless sensor network. Finally...
An approach of mode analysis and excitation for slot antennas has been presented, which is based on a concept of impedance matching between the source and the slot modes. Wideband and multiband features of the slot antenna have been achieved by adjusting the frequency ratio between the slot modes. Several examples have been examined to demonstrate the effectiveness of the proposed approach.
This paper describes an optimization scheme of 3-dimensional wireless sensor networks for topology control. Motivated by the optimal rigid graph, we propose a 3-dimensional optimally rigid topology (3DORT) to reduce the average node degree and lower the energy consumption. In the paper, we analytically prove several important properties for 3DORT: 1)the topology built by 3DORT is 3-connected; 2)the...
Since the energy constraint is a fundamental issue for wireless sensor networks (WSNs), the expectation of network lifetime has become a critical performance index. In actual applications, due to the data traffics may fluctuate randomly, there is a compelling need for a routing strategy that is robust to the variation amplitude of time varied data traffics. In this paper, we jointly consider the lifetime...
A novel multi-agent particle swarm optimization algorithm (MAPSO) is proposed for power load control system in this paper, which regards the large number of highly decentralized regional power load as the rotating adjustable energy power resource to reduce peak or fill valley. The algorithm doesn't only have the advantage of agent to self-government to update its own state, but also has the advantage...
Aiming at the problem of index to evaluate the capability of regional technological innovation in a large quantity and the problem of the impact on assessment results caused by the correlation among the indicators, the paper creates the evaluation indicator system from the input, supporting, and the output three aspects based on the analysis of the components of system. Combined with the economic...
In some specific applications such as industrial control, emergency response, to guarantee the quality of network, some other requirements such as real-time and reliability of transportation, beside the energy consumption, should be considered. In this paper, a novel routing protocol named DETR (delay-energy tradeoff with reliable communication) for Wireless Sensor Networks is proposed, which considers...
In wireless sensor networks, how to efficiently use the energy of the nodes while assigning global unique ID to each node is a challenging problem. By analyzing the communication cost of the clustering and topological features of a sensor network, we present a distributed scheme of Energy Efficient Clustering with Self-organized ID Assignment (EECSIA). In the context of EECSIA, a network first selects...
Heavy truck and bus manufactures in automotive applications extensively use the SAE J1939 protocol definition. In this paper, the SAE J1939 protocol base on CAN bus was discussed. The real-time parameter is a key point of protocol's performance evaluation. The most important thing is to give an effective and reasonable method to simulation. Based on the analysis of the Data Link layer of CAN bus protocol,...

In this paper, we introduce Service Storm, a novel self-service telecommunication Service Delivery Platform with Platform-as-a-Service technologies...
Business agility is of vital importance to chemical and petroleum industry, especially in rapid response to diagnose and exchange of real-time information and other relevant data sources. From IT perspective, emerging delivery models such as cloud computing offer the possibility to build the elastic infrastructure and flexible computing platform, thus enable enterprises to focus on their core competences...
With the popularity of cloud computing, Platform-as-a Service (PaaS) becomes one of the core technical enablers by enterprise to change the services to both customers and internal organizations. An application in an enterprise needs to take into account various specific requirements for hosting in private and hybrid cloud, with unique requirements on rapid development, simplicity for deployment and...
With the popularity of SOA, SOA policy becomes one of the core technical enablers for SOA governance and management. Different in several aspects from traditional policy for distributed system management, policy applied in SOA solutions needs to take into account various policy types and enforcement points in different layers of SOA solution stack and different phases of SOA lifecycle. As well, it...
