Producing caption for the deaf and hearing impaired is a labor intensive task. We implemented a software tool, named SmartCaption, for assisting the caption production process using automatic visual detection techniques aimed at reducing the production workload. This paper presents the results of an eye-tracking analysis made on facial regions of interest to understand the nature of the task, n...

A computational market is any collection of software agents interacting through a price system. Markets can provide eeective allocation of resources for a variety of distributed environments, and economic analysis a powerful design tool for interaction mechanisms. The spread of computational markets puts a premium on market-aware agents, and presents a case for market awareness on the part of a...

In this paper we explain our vision for a new generation of software design environments. We aim to generalize existing software development tools in several key ways – which include: integration of rigorous and informal notations, and support for multiple modes of interaction. We describe how we can consolidate the environment by integrating it with other software engineering tools. Furthermor...

The newly developed Yeh-Stratton (Y-S) Strength Criterion was used to study the failure of composite materials with central holes and normal cracks. To evaluate the interaction parameters for the Y-S failure theory, it is necessary to perform several biaxial loading tests. However, it is indisputable that the inhomogeneous and anisotropic nature of composite materials have made their own contri...

In this paper, we analyse the authentication protocol that has been proposed for the so called global mobility network in the October issue of the IEEE Journal on Selected Areas in Communications. Using a simple logic of authentication, we show that the protocol has aws, and we present three diierent attacks that exploit these. We correct the protocol using a simple design tool that we have dev...

Workflow management systems as modelling technique for monitoring, support and control of business processes are under consideration. Problems, related to the assessment of software products, used for the design and exploitation of workflow management systems are presented. The attention is drawn towards the comparison and assessment of such software tools. The results of this assessment are pr...

The cost of knowledge characteristic function was introduced by Card, Pirolli and Mackinlay in 1994 as a design tool. This paper explores the value of deriving the function from system specifications. Automating the process enables technical designers (programmers) to see usability issues.

Software design is a challenging task. Nowadays, no single designer is able to developer a software alone due to the complexity of the current applications. This suggests that software development is a cooperative activity. As cooperative, software development tools need support awareness in order for usable and useful applications to be developed. This paper describes a set of requirements bas...

Run-time reconfigurable approaches for FPGAs are gaining interest as they enlarge the design space for system implementation by sequential execution of temporally exclusive system parts on one or several FPGA resources. In [7], we introduced a novel methodology and a design tool for communication synthesis in reconfigurable embedded systems. In [5], this work was extended by a hierarchical reco...
