Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

The Unified Modeling Language (UML) is a collection of techniques intended to document design decisions about software. This contrasts with systems engineering approaches such as for example Statemate and the Yourdon Systems Method (YSM), in which the design of an entire system consisting of software and hardware can be documented. The difference between the systemand the software level is refl...

Given a set of requirements structured as design problems, we can apply design patterns to solve each problem individually. Much of the published literature on design patterns addresses this problem—pattern association; however, there is no systematic and practical way that shows how to integrate those individual solutions together. We propose a compositional model based on design patterns by a...

Functional design is a process includes function understanding, function recognition, function representation, function modeling and functionto-structure mapping. The effect in TRIZ is extended by multi-pole effect model and effect chain modes, and then the functions and flows in TRIZ are reclassified. The combinative relationships among functions are discussed, and the function modeling based ...

A key element in supporting the development of Web systems is suitable Web modelling languages. Most existing work on Web modelling (such as WebML [1]) has focussed on understanding the structure of the information space and how this relates to the underlying content.These approaches however have rarely addressed the connection between detailed design aspects and the broader information environ...

This article discusses a research/teaching collaboration between Perkins+Will and the University of Cincinnati and a unique design studio that was initiated as part of this collaboration. The studio investigated the relationships between performance-driven design, computational design techniques, integration of analysis tools with the design process and digital fabrication for a building facade...

Computational design is a powerful tool for conceiving and constructing physical artifacts. As researchers invested in making design tools for young people, we believe that the combination of computational design and craft can be highly relevant for young designers interested in aesthetics and making. Youth engagement in these endeavors requires the development of accessible computational tools...

In this paper we present our design tool GUIDE, which allows the user to explore a design in UML interactively by playing a game. The game incorporates both the design model and a specification of what it means for the design to be correct. The central idea of this approach is that the designer can increment the game during a play and gradually add more detail to it. Specification and design ar...

Goal decomposition structures lie at the heart of goal modeling languages such as i*. High-level goals of stakeholders are recursively decomposed into lower level ones and eventually into leaf level tasks to be performed by agents. The decomposition structure can also develop through a bottom up approach whereby higher-level goals are introduced as justifications for existing low-level ones. Th...
