Architectural design rewriting as an architecture description language

Architectural Design Rewriting (ADR) is a declarative rule-based approach for the design of dynamic software architectures. The key features that make ADR a suitable and expressive framework are the algebraic presentation of graph-based structures and the use of conditional rewrite rules. These features enable the modelling of, e.g. hierarchical design, inductively defined reconfigurations and ordinary computation. Here, we promote ADR as an Architectural Description Language

A generic formalism for the semantic modeling and representation of architectural elements

This article presents a methodological approach to the semantic description of architectural elements based both on theoretical reflections and research experiences. To develop this approach, a first process of extraction and formalization of architectural knowledge on the basis of the analysis of architectural treaties is proposed. Then, the identified features are used to produce a template shape library dedicated to buildings surveying. Finally, the problem of the overall model structuring and organization using semantic information is addressed for user handling purposes

Architecturally Artistic Metal of City Ivano-frankivsk(stanislaviv), End of 19th-beginning of 20th Century

In this article we consider a theme concerning the evolution of metal decoration in architecture of the town Ivano-Frankivsk (Stanislaviv), dated XIX - early XX century, this question was analyzed in line with European architectural and artistic trends of that time. Style trends and compositional features were detected through the example of certain types of metal-plastic in the architecture of the town. Special attention was paid to finding ways to preserve valuable historical examples of architectural-artistic metal, which are exposed to destruction. Ancient metal-plastic, which impresses us by the mastery of far-back blacksmiths, adorns most historic buildings in Ivano-Frankivsk (Stanislaviv). It was formed, at each stage of its development, in line with European architectural-artistic trends and reproduces the content of these processes by typological, compositional, stylistic, iconographic, formal features, together with production technique and manufacturing technology. The metal-plastic being a valuable architectural-artistic heritage of XIX - early XX century, which defines the direction of urban modern forging art development, nowadays is exposed to destruction. Undervaluation and low level of research work, concerning Ivano-Frankivsk historic metal-plastic as a cultural heritage object, become one of the reasons that community and some experts do not consider it as an object that influenced the formation of the architectural urban space image and still continues to influence its evolution

Better abstractions for reusable components & architectures

Software architecture (SA) is a crucial component of Model Driven Engineering (MDE), since it eases the communication and reuse of designs and components. However, existing languages (e.g., UML, AADL, SysML) are lacking many needed features. In particular, they provide rudimentary support for connectors, a first-class element in the components and connectors (C&C) architectural view and one of the most reusable architectural elements. This is unfortunate, since the difficult properties that need to be guaranteed for complex systems are mainly the non-functional properties, like throughput, security and dependability, which are greatly influenced by the employed connectors. This work reviews the basic abstractions of the C&C view of SA and examines extra architectural elements which can support the detailed, explicit and separate description of behaviour, interaction and control logic

Reverse-engineering of architectural buildings based on an hybrid modeling approach

We thank MENSI and REALVIZ companies for their helpful comments and the following people for providing us images from their works: Francesca De Domenico (Fig. 1), Kyung-Tae Kim (Fig. 9). The CMN (French national center of patrimony buildings) is also acknowledged for the opportunity given to demonstrate our approach on the Hotel de Sully in Paris. We thank Tudor Driscu for his help on the English translation.This article presents a set of theoretical reflections and technical demonstrations that constitute a new methodological base for the architectural surveying and representation using computer graphics techniques. The problem we treated relates to three distinct concerns: the surveying of architectural objects, the construction and the semantic enrichment of their geometrical models, and their handling for the extraction of dimensional information. A hybrid approach to 3D reconstruction is described. This new approach combines range-based modeling and image-based modeling techniques; it integrates the concept of architectural feature-based modeling. To develop this concept set up a first process of extraction and formalization of architectural knowledge based on the analysis of architectural treaties is carried on. Then, the identified features are used to produce a template shape library. Finally the problem of the overall model structure and organization is addressed

An Architectural Foundation for Relating Features

Consideration of services in the Intelligent Network and telecommunications leads to the definition of ANISE (Architectural Notions In Service Engineering). This is a rigorous language for defining services systematically using a hierarchy of constituent features. The basic telephone call is used as an illustrative example, supplemented by a number of variations that show how ANISE can easily cope with changes to the basic call. An indication is given of how this might be used to detect problem areas that may lead to feature interaction

Style-Based architectural reconfigurations

We introduce Architectural Design Rewriting (ADR), an approach to the design of reconfigurable software architectures whose key features are: (i) rule-based approach (over graphs); (ii) hierarchical design; (iii) algebraic presentation; and (iv) inductively-defined reconfigurations. Architectures are modelled by graphs whose edges and nodes represent components and connection ports. Architectures are designed hierarchically by a set of edge replacement rules that fix the architectural style. Depending on their reading, productions allow: (i) top-down design by refinement, (ii) bottom-up typing of actual architectures, and (iii) well-formed composition of architectures. The key idea is to encode style proofs as terms and to exploit such information at run-time for guiding reconfigurations. The main advantages of ADR are that: (i) instead of reasoning on flat architectures, ADR specifications provide a convenient hierarchical structure, by exploiting the architectural classes introduced by the style, (ii) complex reconfiguration schemes can be defined inductively, and (iii) style-preservation is guaranteed

The el-Atan Tomb: an Early Bronze IVB female burial in the heart of Bethlehem

An Early Bronze IVB tomb was discovered by the MOTA-DACH on June 2009 in the city of Bethlehem, nearby the Milk Grotto. Its architectural features, burials and associated funerary equipment are here considered and compared with those of other Early Bronze IV cemeteries and necropoleis of Southern Levant to grasp the historical-archaeological meaning of this discovery

Element-by-element factorization algorithms for heat conduction

Element-by-element solution strategies are developed for transient heat conduction problems. Results of numerical tests indicate the effectiveness of the procedures proposed. The small database requirements and attractive architectural features of the algorithms suggest considerable potential for solving large scale problems
