We present a novel specification language called JDC to be used at design phase of distributed components. The extensive seek for asynchrony in distributed components demands new techniques for its specification that have not been addressed before. We propose to focus the specification on its data-flow; this allows to reason about inter-component synchronisations produced by a data-driven synch...

This paper deals with 3D modeling of complex architectural elements for virtual 3D scene reconstruction based on images or point clouds. It presents a new method at the opposite of classical photogrammetry and lasergrammetry techniques: parametric components are created and then adapted to the measured data. We have conceived and developed a parametric shape generator tool for virtual 3D recons...

Many computer programs cannot be easily integrated because their components arc distributed and heterogeneous, i.e.. they are implemented in diverse programming languages, use different data representation formats, or their runtime environments are incompatible. In many cases, programs are integrated by modifying their components or interposing mechanisms that handle communication and conversio...

A major cause of many complications in the field of software architectures is the lack of appropriate abstractions for separating, combining and encapsulating concerns of various kinds in architectural descriptions. Architectures of most complex software-intensive systems involve concerns that inherently crosscut the natural boundaries of the elements composing the architecture descriptions. Cr...

In this paper we show how software architectural styles can be used to guide object-oriented design. Design guidance is important as the initial phases of software design signiicantly impact software quality. We use two diierent architectural styles to guide the design process from a formal speciication to a design. Software architectural styles assist by providing a diierent level of reuse tha...

Eukaryotic cells use multiple routes for receptor internalization. Here, we examine the topographical relationships of clathrin-dependent and clathrin-independent endocytic structures on the plasma membranes of leukemia-derived mast cells. The high affinity IgE receptor (FcεRI) utilizes both pathways, whereas transferrin receptor serves as a marker for the classical clathrin-mediated endocytosi...

Commercial off-the-shelf (COTS) software components are built to be used as black boxes that cannot be modified. The specific context in which these COTS components are employed is not known to their developers. When integrating such COTS components into systems, which have high dependability requirements, there may be mismatches between the failure assumptions of these components and the rest ...

A rigorous paradigm coordinating components is important in the design stage of large-scale software engineering. In this paper we propose a new Architecture Description Language, called ACDL, to represent the centralizedmode architectural connection in which all components are linked by a single connector. Following one usual approach to architectural description, in which component types and ...

Software development is a costly process for all but the most trivial systems. One of the commonly known ways of minimizing development costs is to re-use previously built software components. However, a significant problem that source-code re-users encounter is the difficulty of finding components that not only provide the functionality they need but also conform to the architecture of the sys...
