Internet-based computing is booming. This has brought positive effects on education and engineering design practice. This paper introduces the development details on a web-based symbolic circuit simulation tool AICE (Analog IC Explorer). Unlike SPICE simulators, symbolic tools are small and compact. Making a symbolic tool available online as a web service has many benefits: 1) cross-platform, 2) wide...
Cloud resource management research and techniques have received relevant attention in the last years. In particular, recently numerous studies have focused on determining the relationship between server-side system information and performance experience for reducing resource wastage. However, the genuine experiences of clients cannot be readily understood only by using the collected server-side information...
In this paper we present our ongoing study and deployment efforts for enabling FPGAs in datacenters. An important focus is to provide a quantitative evaluation of a wide range of heterogeneous system designs and integration options, from low-power field-programmable SoCs to server-class computer nodes plus high-capacity FPGAs, with real system prototyping and implementation on real-life applications...
With the cloud storage of booming development in recent years, the synchronization technology between smartphones and servers will get more attention and better development. In this paper analyzes the data synchronization library libsyncml overall framework, and identifies potential performance bottlenecks in the framework, and then uses the thread pool and other ways to improve the synchronization...
In this paper we propose an efficient Large-scale terrain visualization system in a cluster environment. Firstly, we implement level-of-detail (LOD) building in parallel, with an obvious time saving compared with a single-machine environment. The LODs are then stored in the server. While rendering, clients get LODs on demand. LODs are organized with a scene graph structure, thus view frustum culling...
With the high frequent occurrence of large scale of blackouts and the development of smart grids, wide-area protection and control system (WPCS) with synchrophasors becomes the research focus. Since the performance and the reliability of WPCS are crucial for the security of the system, it is of great importance to test the system carefully before its commission. However, it is hard to solve this problem...
This paper novel proposes a flexible RFID based production process management system architecture with the service oriented architecture technology. The system managers can add a new function or a new production process by the visual interface of our architecture. This architecture is used to construct a visualization system prototype which can be used to manage laundry process effectively by using...
For TCP/IP Agreement has certain security bugs, the hacker catches the opportunity to attack the Network. On the basis of the analysis of the TCP/IP Agreement's vulnerability, the article has further analyzed the vulnerability of the Transport Layer Agreement, and discussed the security and the promotion method of TCP/IP Agreement's transport layer.
As a part of Cloud computing, Software as a Service (SaaS) enables users to cut their costs by outsourcing software as a service on-demand, in which both computation and storage are handled on server-side. However, data must be decrypted into memory when performing the computation, even though they can be encrypted during storage and transmission. In this case, the privileged administrators of SaaS...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
To prevent file transmission in the electronic military affair system from being damaged. Methods: security mechanisms of Web service based on J2EE platform, system security based on RSA algorithm, and the basic principle of digital signature. Procedure: to explain definition, characteristics and structure of the electronic military affair system, and to analyze its design process and security. Conclusion:...
This paper introduces a neural network training tool through computer networks. The following algorithms, such as neuron by neuron (NBN) , error back propagation (EBP), Levenberg Marquardt (LM) and its improved versions are implemented in two different computing methods, traditional forward-backward computation and newly developed forward-only computation. The training tool can handle not only conventional...
Scale-out approach, in contrast to scale-up approach (exploring increasing performance by utilizing more powerful shared-memory servers), refers to deployment of applications on a large number of small, inexpensive, but tightly packaged and tightly interconnected servers. The purpose of this study is to understand the performance of scale-out architectures with a typical enterprise workload, IBM Trade...
