Preliminary Research

Architectural complexity management of engineering systems is becoming a major issue as systems built nowadays implement more complex technologies and innovations. In this paper, we present a preliminary research finding where quantitative values for an engineering system's architectural complexity are mapped with design effort for individual subsystems that are part of the system architecture. This was done to establish relationships between abstract architectural complexity of engineering systems and metrics that can directly be applied to system design and development. A railroad train driving bogie was used for the case study.

A seven-step framework for sorting proposed concepts of system changes / reconfigurations is presented that seeks to characterize the overall ramifications on system architecture. This framework is intended for use immediately following a concept generation phase. The framework uses three simple questions: “What level of the system design does this concept apply to?” “What levels of the system design does the concept impact?” and “What is the severity of this impact?” A flowchart leads the designer through these questions and assigns each concept a classification from one to five based on the answers. Class one concepts have little to no impact on the rest of the system architecture. They can be included with little fear of massive change propagation and system redesign. Class five concepts carry large changes to system architecture and therefore should be included only if they can be shown to be highly beneficial, or if there remains enough design freedom such that the cost of changing the system architecture is minimal. Meanwhile, class five concepts are likely to have much higher potential to create revolutionary design. A case study is used to demonstrate the application of the sorting framework in the context of a Mars rover mission. Several example concepts are provided to illustrate key insights from the case study. Convergence of the framework is explored by comparing the authors’ results to a second test done by a new design team.

In contrast with low end microprocessor, ARM9 core is quite a sophisticated processor. The Evaluation kit plays an important role in the prototype development and verification of the system design before taking to its actual system development hence it’s provide better confidence to the designer. In this paper a project for the Evaluation kit has been designed for embedded system engineer to implement and confirm the functionality of their operating systems which could lead to a comfortable deployment. The independent modules for the interfaces of the ARM9 processor have been designed and the schematics have been developed using OrCAD. From the tested schematics designed in OrCAD, the related PCB is designed using CADSTAR. An eight-layer board is designed for its signal integrity and complexity of the schematic designed. The designed PCB layer is then calibrated and Gerber files are then made and passed on the PCB board manufacturer for PCB fabrication. The PCB board made is then tested for interconnection continuity using multi-meter as the components are loaded on to the board.

Automation Framework

Cyberphysical system design automation utilizing knowledge based engineering techniques with globally networked knowledge bases can tremendously improve the design process for emerging systems. Our goal is to develop a comprehensive architectural framework to improve the design process for cyberphysical systems (CPS) and implement a case study with Axiomatic Design Solutions Inc. to develop next generation toolsets utilizing knowledge-based engineering (KBE) systems adapted to multiple domains in the field of CPS design automation. The Cyberphysical System Design Automation Framework (CPSDAF) will be based on advances in CPS design theory based on current research and knowledge collected from global sources automatically via Semantic Web Services. A case study utilizing STEM students is discussed.

AbstractThis paper discusses the uses and applications of the Pedagogy of Experience Complexity for Smart Learning (PECSL), a four-tier model of considerations for the design and development of smart learning activities. Using existing mobile apps and relevant activities as illustrative examples, the PECSL is applied to indicate concepts and mechanisms by which useful pedagogical considerations can work alongside user-centred design principles for the design and development of smart learning in urban hyper-localities. Practical application of the model is discussed using real world examples of activities as a basis to demonstrate the potential for manifold opportunities to learn, and plan for experience complexity in a smart learning activity. Case study approaches reflect on aspects of the PECSL in how it might be a useful and pragmatic guide to some of the issues faced when designing digital citizen learning activities in complex urban environments.
