As the size and complexity of software systems increases, the design and speci cation of overall system structure|or software architecture|emerges as a central concern. Architectural issues include the gross organization of the system, protocols for communication and data access, assignment of functionality to design elements, and selection among design alternatives. Currently system designers ...

Models are gaining importance in software development, for instance in the MDD field, as well as in other disciplines such as biology and physics. Hence, tool support is needed to manage these models and metadata about the models. Model repositories support this trend by managing these model artifacts. While setting up model and metadata repositories, architects have to make several fundamental...

Service-oriented architectures have become prevalent in enterprise information systems. The underlying infrastructure is typically architected with multiple tiers in order to separate the different concerns such as interface, business logic and data. Modern information systems have strict availability and scalability requirements. The main technique to attain these properties is replication. Ho...

Software architectural design has an enormous effect on downstream software artifacts. Decomposition of function for the final system is one of the critical steps in software architectural design. The process of decomposition is typically conducted by designers based on their intuition and past experiences, which may not be robust sometimes. This paper presents a study of applying the clusterin...

The PSL (Process Specification Language) project is creating a standard language for process specification to serve as an interlingua to integrate multiple process−related applications throughout the manufacturing life cycle. This interchange language is unique due to the formal semantic definitions (the ontology) that underlie the language. The PSL ontology is organized modularly with a small ...

The cities, environments and buildings we live in have been the result of change since old times. In the course of time, together with the changes in the socio-culture and value judgments, all of the economic and technological changes have reflected into architecture. As a result, in the urban environment and architectural residences, the contemporary solutions have been provided. Yet, these so...

Emotion mechanisms are often used to perform roles in artificial agents with the aim of improving task performance. A basis for making comparisons between these agents is proposed, in the form of a framework constructed from an analysis of architectural qualities (the agent architecture, the action selection mechanism, and the emotion mechanism along with the emotion model it was based on). Thi...

Chromosomes of metazoan organisms are partitioned in the interphase nucleus into discrete topologically associating domains (TADs). Borders between TADs are formed in regions containing active genes and clusters of architectural protein binding sites. The transcription of most genes is repressed after temperature stress in Drosophila. Here we show that temperature stress induces relocalization ...

| A method is presented for the stepwise reene-ment of an abstract architecture into a relatively correct lower-level architecture that is intended to implement it. A reenement step involves the application of a predeened re-nement pattern that provides a routine solution to a standard architectural design problem. A pattern contains an abstract architecture schema and a more detailed schema in...
