Layered Components
نویسنده
چکیده
We describe a generic software environment intended to assist the construction of applications by the composition of reusable components. Two classes of components (and their related systems) are clearly distinguished: operational components (or components in the ’classical’, technological sense) and descriptive components, encapsulating meta-data about, amongst others, their operational counterparts. Components are viewed as actors in a communicating entities system. Communications capabilities and needs are abstracted as a set of layers, each layer denoting a delimited conventions set and satisfying or dictating functional requirements. A case study describes how we are using or intend to use our models in real life applications. The selected case consists in the interconnection of two, otherwise incompatible, CASE tools.

Analyzing and explaining the dimensions and components of the layered curriculum in line with the student-centered approach
To create a learner-centered learning environment, teacher and students must add new dimensions to their traditional roles. This research was conducted qualitatively and with thematic analysis approach. To achieve the set goal, a structured interview was conducted with curriculum experts. The samples were selected in a purposeful manner based on specific criteria. Data analysis started from the...
متن کاملLayered Connectors - Revisiting the Formal Basis of Architectural Connection for Complex Distributed Systems
The complex distributed systems of nowadays require the dynamic composition of multiple components, which are autonomous and so complex that they can be considered as systems in themselves. These components often use different application protocols and are implemented on top of heterogeneous middleware, which hamper their successful interaction. The explicit and rigorous description and analysi...
متن کاملThermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure
The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...
متن کاملComposite piled raft foundation with intermediate cushion in layered soil under seismic forces
In order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. In the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...
متن کاملATLAS: A generic software platform for speech technology based applications
ATLAS is a Java software library that provides a framework for building multilingual and multi-modal applications, especially dialogue systems, on top of speech technology components. The design is based on a layered system model, where ATLAS sits as a middleware between an application-dependent layer and the speech technology components and implements much of application-independent functional...
متن کاملSIGGRAPH Asia 2009 Course Exploring the Potential of Layered BRDF Models
This course serves as a guide on the considerable potential of layered surface models. The key advantage of using such layered BRDFs over traditional, more general shading language constructs is that the end result is automatically highly physically plausible. In particular, we demonstrate on a simple layered surface model that combines several traditional BRDF components how a surprisingly lar...
