The Encapsulation of Finite Element Analysis Process about Bogie’s Side Frame Based on EASA

Taking into account the problem of plenty repeated works during the operation of engineering application software, the integrated solution of engineering application software based on EASA (the encapsulate tools of software) was proposed for improving the analysis efficiency and ensuring the analysis accuracy of software purpose. Then taking the strength analysis of bogie’s side frame as an example, the integrated analysis interface of strength analysis about side frame was established, realized the remote invocation based on Web, and the efficiency of engineering analysis was improved.

Facilitating Preemptive Hardware System Design Using Partial Reconfiguration Techniques

In FPGA-based control system design, partial reconfiguration is especially well suited to implement preemptive systems. In real-time systems, the deadline for critical task can compel the preemption of noncritical one. Besides, an asynchronous event can demand immediate attention and, then, force launching a reconfiguration process for high-priority task implementation. If the asynchronous event is previously scheduled, an explicit activation of the reconfiguration process is performed. If the event cannot be previously programmed, such as in dynamically scheduled systems, an implicit activation to the reconfiguration process is demanded. This paper provides a hardware-based approach to explicit and implicit activation of the partial reconfiguration process in dynamically reconfigurable SoCs and includes all the necessary tasks to cope with this issue. Furthermore, the reconfiguration service introduced in this work allows remote invocation of the reconfiguration process and then the remote integration of off-chip components. A model that offers component location transparency is also presented to enhance and facilitate system integration.

SAMEVED

Cloud computing is an emerging computing paradigm that provides all kinds of services through the Internet. Existing elastic computing approaches are popular in cloud computing. They can fulfill the requirements of some cloud applications, but usually fail to provide an isolated computing environment consisting of connected virtual machines over a user-defined network topology. This paper presents a system architecture, namely SAMEVED, which exposes a cloud service that can allocate and manage a private, virtual elastic datacenter by integrating VPN and virtual routers into existing virtualization technologies. Authentication is required by user login while using SAMEVED. A user-friendly web interface and remote invocation interface are provided to support different operations for different users with different privileges.

Enterprise Integration Technical Foundation

In an organization, its business changes in a variety of ways over time, and so do its underlying supportive IT systems. For example, the changes required at Malvern iStore were clearly shown in last chapter; one positive change that would make a significant impact on the growth of business at Malvern iStore is to conduct effective enterprise integration. Note that the underlying distributed applications and the corresponding business and operational needs vary from organization to organization, and there is surely no one-size-fits-all solution to integrating distributed applications to meet a variety of needs across organizations. As discussed in last chapter, a solution might be technically optimal, but it might not be viable financially or due to other restrictions like human capitals and time constraints. However, for organizations, no matter which approach and technology will be applied in conducting enterprise integration, in a small or large scale fashion, the ultimate goal should be the same – improving the business’s competitiveness. This chapter starts with the discussion of the foundation of enterprise integration, focusing on the basic integration mechanisms, patterns, and technologies that have been applied in integrating distributed applications over the years. Different methods of sharing data and functionality between applications will be first introduced. Certain explorations on the differences between sharing data and functionality will be presented. As socket communications, remote procedure calls, and remote invocation methods are the foundation of the middleware technology and state-of-the-art service computing, numerous relevant examples are provided.

The Research of OSGi Remote Invocation Based on Agent

D-OSGi call on the remote service by Webservice ,which accessing through the SOAP based-on HTTP and publishing the service By WSDL .But when publishing the service ,we need configuring the XML file, facing so many documents ,the System will delay than before, and influences the performance. Every Service registered by UDDI has no safety policy. Therefore, it propose Agent when invoking the remote service on this paper, we can publish the service By Agent and no long use the configuration document. by this way, we can guarantee the safety of revoking service.

INTEGRATING REMOTE INVOCATIONS WITH ASYNCHRONISM AND COOPERATIVE MULTITASKING

In this paper we argue that it is possible to couple the advantages of programming with the well-known abstraction of RPC with asynchronous programming models adequate for wide-area programming environments such as grids. We discuss how some programming language features can help create different programming abstractions over a basic asynchronous invocation primitive. The paper also discusses how coroutines (cooperative multitasking) can be used to allow computation to proceed while a client is waiting for the result of a remote invocation, avoiding the pitfalls of programming with threads.
