The paper provides an overview of the basic concepts of OMG CORBA. It summarizes the main ideas behind the OMG Reference Model Architecture and the components it defines. Particular attention is paid to the Object Request Broker and Object Services. An evolving example is used to illustrate the CORBA philosophy. The authors draw on their long-term practical experience with CORBA, particularly w...

The objective of this work is to assess the qualities of the MOFScript language, which has recently been submitted to the OMG as a proposed model to text transformation language. This is done by identifying requirements for this type of language and evaluating the MOFScript language with regard to these. The language is presented along with a tool implementation and compared with the alternativ...

OMG (Object Management Group) DDS (Data Distribution Service for Real-time Systems) is an open international communication middleware standard for real-time and embedded systems. In this paper, a communication middleware model based on OMG DDS for multi-robot environments is presented. With the help of DDS QoS mechanism and Publish/Subscribe paradigm, proposed communication middleware abstracts...

Hexokinase-deficient mutants and wild-type Chinese-hamster ovary cells have been used to investigate the role of hexokinase in uptake and accumulation of 2-D-deoxyglucose (2-dGlc). The evidence for a specific sugar transport system in both types of cells is that there is similar saturable phloretin-sensitive uptake of 2-dGlc and 3-O-methyl-D-glucose (3-OMG) in both types of cell. In wild-type c...

This document is in response to the OMG Real-Time technologies RFI (ORBOS/9609-02). It is intended to provide responses to Requirements, Approach, Categories, Architecture and Technology aspects for integrating real-time technologies into OMG’s CORBA. This response is based on work done in the ReTINA ACTS project (project AC048) which purpose is to develop a flexible, real-time ORB, and on the ...

Because of their unique physical properties, three-dimensional (3D) graphene has attracted enormous attention over the past years. However, it is still a challenge to precisely control the layer thickness of 3D graphene. Here, we report a novel strategy to rationally adjust the wall thickness of ordered mesoporous graphene (OMG). By taking advantage of ligand exchange capability of colloidal Fe...

Modern Web-based Information Systems (WIS) are becoming increasingly necessary to provide support for users who are in different places with different types of information, by facilitating their access to the information, decision making, workgroups, and so forth. Design of these systems requires the use of standardized methods and techniques that enable a common vocabulary to be defined to rep...

The objective of the paper is to present an innovative environment (Application Construction Environment ACE) for the specification, the development and the generation of Telecommunication applications according to the TINA and OMG standards. The functionalities offered by the environment are outlined in the following sections, in addition to experiences of usage of ACE for specification activi...

While the current OMG standards such as the Meta Object Facility (MOF) [MOF] and the UML [UML] provide a well-established foundation for defining PIMs and PSMs, no such wellestablished foundation exists for transforming PIMs into PSMs [GLR+02]. In 2002, in its effort to change this situation, the OMG initiated a standardization process by issuing a Request for Proposal (RFP) on Query / Views / ...

OMG is mainly famous for its CORBA and IDL activities. In the various working groups of this organization, many different themes are however studied, with the same industrial consensus process that has made the success of CORBA, IDL, IIOP and many other middleware recommendations. Some of the outcomes of these efforts have already gained an important notoriety, like the Unified Modeling Languag...
