Fixed-wing aircraft are viewed as no longer satisfying our needs today. In the past ten years, fuel efficiency and noise reduction have become the two biggest challenges for aircraft manufacturers. The recognition spurred aerospace engineers and system architects to come up with the Blended Wing Body (BWB), a new design for next generation aircraft. In this paper, we discuss the development of ...

Requirements validation is a crucial process to determine whether client-stakeholders’ needs and expectations of a product are sufficiently correct and complete. Various requirements validation techniques have been used to evaluate the correctness and quality of requirements, but most of these techniques are tedious, expensive and time consuming. Accordingly, most project memb...

The engineers who analyze traac on high band-width networks must lter and aggregate either recorded traces of network packets or live traac from the network itself. These engineers perform operations similar to database queries, but cannot use conventional data managers because of performance concerns and a semantic mismatch between the analysis operations and the operations supported by commer...

Computational grid portals are becoming essential tools in automotive companies world-wide for managing compute resources for virtual engineering and design. Many automotive and associated manufacturing industries are taking initiatives for making the computing resources transparent from the integrated design environment. This paper illustrates how the grid portal technologies can fulfil these ...

Rather than designing engineering systems from the ground up, engineers often redesign strategic portions of existing systems to accommodate emerging needs. In the redesign of mechatronic systems, engineers typically seek to meet the requirements of a new application via control redesign only, but this is often insufficient and physical system (plant) design changes must be explored. Here, an i...

Software evolution is a natural phenomenon. As the software undergoes changes, it needs to be tested for the changes made along with the unchanged parts for consistency. This activity gradually increases the size of the test suite and becomes a challenging task for a software engineer to perform regression testing in a constrained environment of limited time. The activities of test case selecti...

This paper seeks to address a problem ubiquitous in many software development environments today, namely, building software from requirements that are incomplete and not fully understood, thereby creating products that are either faulty or ultimately not being used at all. This gap that exists between software engineers and clients is highlighted in this paper and suggestions on how to overcome...

Dust explosions always claim lives and cause huge financial losses. Dust explosion risk can be prevented by inherently safer design or mitigated by engineering protective system. Design of explosion prevention and protection needs comprehensive knowledge and data on the process, workshop, equipment, and combustible materials. The knowledge includes standards, expertise of experts, and practical...

The day-to-day experiences of aging citizens differ significantly from young, technologically savvy engineers. Yet, well-meaning engineers continue to design technologies for aging citizens, informed by skewed stereotypes of aging without deep engagements from these users. This paper describes a co-design project based on the principles of Participatory Design that sought to provide aging peopl...

Technical systems are becoming increasingly integrated, e.g. because of the intensive use of software due to demands on energy efficiency, performance and customisability. This means that there are a lot of interactions among the sub systems during operation. The dynamical behaviour of such a system is hard to predict since every sub system needs to be taken into account. Also, often the sub sy...
