In today's datacenters, resource requests from tenants are increasingly transforming into hybrid requests that may simultaneously demand IaaS, Paas, and SaaS resources. This paper tackles the challenge of modeling and deploying hybrid tenant requests in datacenters, for which we coin "networklet" to represent a set of VMs that collaboratively provide a PaaS or SaaS service. Through extracting...
In order to improve the operational safety and equipment management of nuclear power plants, combined with domestic and foreign nuclear power plants reliability data of actual demands, development of equipment reliability data collection and analysis application platform research work have been performed. This paper presents the research technique and research ideas, establishes the reliability of...
Location tracking for vehicle plays a key role in increasing road safety and transportation efficiency. In this paper, a Wi-Fi based real-time tracking system which can work in both indoor and outdoor environments is presented. The proposed system estimates the location of vehicle using the Received Signal Strength (RSS) fingerprints of transmitted Wi-Fi Access Points (APs) and Particle Filter (PF)...
Providing an anytime, ubiquitous and reliable vehicular positioning system plays a key role in increasing road safety and transportation efficiency. Although the Global Positioning System (GPS) has been widely used in vehicle navigation, urban vehicle positioning is still a challenge because of the unavailability of GPS in dense metropolitan areas. To solve this problem, an advanced integration of...
In this study, the SNPs located in the chicken pre-microRNAs were performed a genome-wide analysis. The result showed that pre-microRNA SNPs are negatively selected in respect to SNPs distribution between the pre-microRNA and their flanking regions. Interestingly, the seed regions show a higher SNP density than both the MIR and the other MIR regions excluding seed regions. Furthermore, the SNPs in...
The domestic commercial banks build a new generation of business system by the introduction of the overseas core business system. It has become a trend over the next few years that integrating various business channels by centralizing business platforms and altering the business model based on accounting treatment into the operation model of customer-oriented. This paper reports the key technology...
As an example of SIMS (student information management system) developed independently by School of Information Science & Engineering of Shandong Normal University, this paper introduces database design, specific realization of each function module and key technologies used in the system. In the .NET environment, using ASP.NET technology, Visual C# and JavaScript as programming language, this system...
This paper firstly introduces the forming and development of decision support systems, then analyzes problems of decision support systems development, and points out technology problem in designing human-computer dialogue system, data extracting from decision support systems database, inquiry speed problem of decision support systems database. Lastly it expounds the trends of decision support systems...
Recovery from information attacks is difficult because DBMS is not designed to deal with malicious committed transactions. A few existing methods developed for this purpose rely on operation logs, which can't express the dependency between different transactions directly. These methods usually use rollback mechanism and abandon results of innocent transactions to maintain correctness, which may indeed...
