An improved technique for the design synthesis of a spring-actuated, cam-follower system is described. Long-hand calculations and a simple graphical technique suffice to design a system to meet prescribed dynamic performance characteristics. By analysis of a simplified model, the response of the system to the impact accompanying take-up of clearance is related to four dimensionless parameters. A comparison of theory and tests on one design substantiate the utility of the synthesis technique and also provide additional insights into the dynamic behavior of such systems.

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.

An approach to an ontology-based information system design theory for spatial information system development is presented. This approach addresses the dynamic nature of information system development at the beginning of the 21st century and addresses the question of how to establish relationships between the various design components of a spatial information system. It should also help to automate and guide the design process while at the same time improve the quality of the process along with its outputs. An example of this approach is presented, along with examples of the various ontologies utilized in the design of this particular spatial information system. Finally, a method to mitigate the issues regarding the organization and management of a growing library of ontologies is discussed.

As one of the workload characteristics, the anomaly behaviors in real workload have been recognized as a critical requirement for file system design. In this paper, a set of traces collected from typically realistic file system have been analyzed. The correlation study of I/O request inter-arrival times shows that it is necessary to examine the self-similarity in file system workload. Then the phenomenon of self-similarity which had been initially observed in network and disk I/O workload has also been visually and statistically observed in file system workload. In addition, we implement an I/O series generator in which the inputs are the measured properties of the available trace data. Experimental results show that this model can accurately emulate the complex access arrival behaviors of real file systems, particularly the heavy-tail characteristics.
