During the past 45 years there has been a recurrence of interest on supporting sketching at electronic devices and interactive surfaces, and despite being sketching recognition fairly well addressed on the literature, the adoption of electronic sketching as a design tool is still a challenge. The current popularization of touch screen devices allows designers to sketch using their device of pre...

This paper presents a method for assisting the optimal selection of topologies for the minimum-weight design of continuum structures subject to stress constraints by using the performance index (PI ). A performance index is developed for evaluating the efficiency of structural topologies based on the scaling design approach. This performance index is incorporated in the evolutionary structural ...

The fashion industry is one of the most flourishing fields for visual applications of IT. Due to the importance of the concept of look in fashion, the most advanced applications of computer graphics and sensing may fruitfully be exploited. The existence of low cost solutions in similar fields, such as the ones that empower the domestic video games market, suggest that analogous low cost solutio...

This paper presents a novel narrowband microstrip patch antenna for radar application. The proposed antenna consists of rectangular radiating patch which provides a narrowband behavior and relatively good impedance matching working in the band of 3-12 GHz. A parametric study is performed on three different antenna structures. The measured results give three narrow band stable signal transmissio...

This paper describes how the Prometheus Design Tool (PDT) is used to support the Prometheus methodology for designing agent systems. This is done by using an exemplar system that has been used previously in the literature, and is briefly described earlier in this volume. This paper presents the development of a design for this system using PDT. By using different tools and methodologies to desi...

We use metamodeling for Object Oriented database design and management. First, in the context of the UMLbased metamodeling, we provide an overview of what is achievable, e.g., more exhaustive descriptions of classes (their behaviors and their dependencies), validation of external schemas of a database, as well as determination of requirements for software tools to enhance system security. Secon...

This is an instruction manual for the aerodynamic lens design tool: the “Aerodynamic Lens Calculator”. We explain how to install and use this software. Examples are provided to use this tool to design or test a lens system. The structures of the source code programming are also provided in this manual. The design tool and its manual mentioned in this article are available in the publisher’s onl...

This paper presents a survey of products of real-time software framework which is composed of software modules for building distributed control systems. This survey mainly deals with the architecture and the design tool of real-time software framework. In addition, it describes the commercial and the academic products of real-time software framework. Finally, this paper compares various product...

The ability to simulate at the microscopic level all terminal transport processes is of paramount importance to ports and terminals, to the industry, to a wide range of multidisciplinary researchers, and to many other stakeholders. In a microscopic simulation, every significant piece of equipment is modeled and tracked. Terminal operators report that such detailed modeling capabilities do not e...

The Network Modeling Tool (NetMod) uses simple analytical models to provide the designers of large interconnected local area networks with an in-depth analysis of the potential performance of these systems. This tool can be used in either a university, industrial, or governmental campus networking environment consisting of thousands of computer sites. NetMod is implemented with a combination of...
