In this paper we describe a system that allows a power wheelchair user to drive through a virtual architectural environment. The system allows architects and designers to visualize an environment, test the environment for handicapped accessibility, and determine whether the environment meets design standards such as the Americans with Disabilities Act of 1990. First we describe the system itsel...

Cable-stayed bridges are extremely elegant and very effective structures and they are also architectural landmarks. The combination of multiple simple systems allows for a structure where the role of each of its components is well defined. When a cable-stayed bridge is chosen, the initial design phase is of utmost importance. The characteristics of the structure and whether if it is mainly cons...

In a component-based software system the different components communicate with each other through their interfaces, possibly using adapters. Whenever the requirements or the environment change, the component-based software system must be adapted accordingly. We present a method that supports a systematic evolution of component-based software at the architectural level. It is based on operators ...

We present a design flow for the generation of application-specific multiprocessor architectures. In the flow, architectural parameters are first extracted from a high-level system specification. Parameters are used to instantiate architectural components, such as processors, memory modules and communication networks. The flow includes the automatic generation of communication coprocessor that ...

The design model helps to translate the architectural model into suitable logical abstractions that could be used to semantically represent the architectural components and explicate their intricacies in the design domain. The implementation model is the next step towards physically realizing the architecture and design by helping to map the logical abstractions into high-level language entitie...

In this paper, we leverage software architecture analysis techniques to codify change management properties and to examine their affect on the functional integration of software components. Software architecture provides a means to predict and analyze the potential for interoperability problems among interacting components. However, the properties addressed in traditional software architecture ...

Large scale Open Systems are built from reusable components in such a way that enhanced system functionality can be deployed, quickly and effectively, simply by plugging in a few new or revised components. At the architectural level, when new variations of a system are being planned by (re)configuring reusable components, the architecture description can itself become very large and complex. Co...

We describe High-level Library Mapping (HLLM), a technique that permits reuse of complex RT-level databook components (speciically ALUs). HLLM can be used to couple existing databook libraries, module generators and custom-designed components with the output of architectural or behavioral synthesis. In this paper, we deene the problem of high-level library mapping, present some algorithmic form...

In the context of the authors’ research on architectural features recovery, abstract data type (ADT) and abstract state encapsulation (ASE, also called abstract object) have been identified as two of the smallest components which are useful to build a significant architectural overview of the system. The authors have named these the atomic components of an architecture. This paper compares five...
