An OSCA™ architecture characterization of network functionality and data

This article demonstrates that the Bellcore OSCA architecture can serve as a basis for the metaarchitecture for software architectures that must support interoperability among functionality that traditionally has resided in operation systems and functionality that traditionally has resided in network elements (NE) (i.e., interoperability among operations functionality and network functionality). The need for this interoperability is driven by such telephone company business needs, as the need for customers to access operations capabilities spanning operations systems and NEs, the need for new service offerings to span operations systems and NEs, the need for a flexible environment for service development, and the need to manage all corporate data as a company resource. As a result, it is becoming beneficial to apply interoperability requirements to the network functionality that interfaces with operations systems. Therefore, it is reasonable to apply the OSCA architecture to network functionality. This article applies the OSCA architecture interoperability principles of separation of concerns to current and emerging network functionality. It demonstrates that this functionality can be partitioned among the three OSCA architecture layers of corporate data, processing, and user, and that there are a number of benefits to applying the OSCA interoperability principles to network functionality.     

Functionality Evaluation Model for Machine Translation Systems

The principal concepts, models and methods for software quality evaluation are presented. Since the definitions of functionality in the existing standards for software quality evaluation are inconsistent, this concept here is defined as a particular case of the concept of quality in qualimetry as applied to software quality evaluation. A generalized model for software functionality evaluation is proposed. A functionality evaluation model for machine translation systems that was developed based on it and can be a prototype for more detailed models is given. Some ways to use such models to evaluate the functionality of machine translation systems numerically are considered.     

Functionality Representations and Applications for Shape Analysis

A central goal of computer graphics is to provide tools for designing and simulating real or imagined artifacts. An understanding of functionality is important in enabling such modeling tools. Given that the majority of man‐made artifacts are designed to serve a certain function, the functionality of objects is often reflected by their geometry, the way that they are organized in an environment, and their interaction with other objects or agents. Thus, in recent years, a variety of methods in shape analysis have been developed to extract functional information about objects and scenes from these different types of cues. In this report, we discuss recent developments that incorporate functionality aspects into the analysis of 3D shapes and scenes. We provide a summary of the state‐of‐the‐art in this area, including a discussion of key ideas and an organized review of the relevant literature. More specifically, the report is structured around a general definition of functionality from which we derive criteria for classifying the body of prior work. This definition also facilitates a comparative view of methods for functionality analysis. We focus on studying the inference of functionality from a geometric perspective, and pose functionality analysis as a process involving both the geometry and interactions of a functional entity. In addition, we discuss a variety of applications that benefit from an analysis of functionality, and conclude the report with a discussion of current challenges and potential future works.     

On integrating confidentiality and functionality in a formal method

This paper proposes a formal method, based on Circus, for developing software systems that respect a joint specification of functionality and confidentiality attributes. We extend the semantics of Circus to capture the information that users can infer about a system’s behaviour, enabling confidentiality and functionality attributes of a system to be specified together. We represent inconsistencies between functionality and confidentiality properties as miracles, rendering insecure functionality infeasible. We present techniques for verifying that a system design’s functionality and confidentiality attributes are mutually consistent, and for ensuring that consistency is maintained by refinement steps.     

A middleware‐transparent approach to developing distributed applications

An innovative middleware‐transparent approach to developing distributed applications is presented. The approach uses an aspect‐oriented software development technique to separate an application's middleware‐independent functionality from its middleware‐specific functionality. Application elements that are specific to the middleware are localized in aspects that can be seamlessly integrated into middleware‐independent application designs. The middleware‐transparent approach is used to decouple business functionality from middleware‐specific functionality. The decoupling allows developers to change middleware application elements without significantly modifying business functionality. Middleware technologies such as Java Remote Method Invocation (RMI), Jini, Simple Object Access Protocol (SOAP) remote procedure call (RPC) and .Net are used as examples to illustrate the approach.

Electro-optic investigations of holographically formed PDLCs: The effect of monomer functionality on display performance

Abstract— We investigated the effect of monomer functionality on the electro-optic performance of holographically formed polymer-dispersed liquid crystals. Oligomers of functionality 2, 3, and 6 are mixed to yield oligomers of intermediate functionality. Reflection efficiency and critical field peaks are reported for an effective functionality of ～4.5 SEM studies, allowing us to correlate these results to polymer morphology.
