Prosthetic Architecture: Enabling Connection, Movement, and Empowerment

This thesis explores the relationship between body and architecture through a metaphorical and literal analysis of prosthetic devices. The thesis questions how the relationship between prosthetics and architecture can inform the design of a building that enables connection, movement and empowerment for its occupants. Driving questions of investigation include: How can a building enable growth, healing and wellbeing? , How can a building embody and reflect human growth and transformation? , and, How can a building enable equivalence between its users? The program of an inpatient prosthetic rehabilitation facility allows for the exploration of these questions and a study for how we can create spaces that influence rehabilitation and growth. Through body and prosthetics analysis the thesis explores what spaces are best for one to grow and develop in and study how concepts, such as connection, movement and empowerment can enable one and enhance one’s quality of life.

Communication Architecture Design for Real-Time Networked Control Systems

Networked control over data networks has received increasing attention in recent years. Among many problems in networked control systems (NCSs) is the need to reduce control latency and jitter and to deal with packet dropouts. This paper introduces our recent progress on a queuing communication architecture for real-time NCS applications, and simple strategies for dealing with packet dropouts. Case studies for a middle-scale process or multiple small-scale processes are presented for TCP/IP based real-time NCSs. Variations of network architecture design are modelled, simulated, and analysed for evaluation of control latency and jitter performance. It is shown that a simple bandwidth upgrade or adding hierarchy does not necessarily bring benefits for performance improvement of control latency and jitter. A co-design of network and control is necessary to maximise the real-time control performance of NCSs

SKMA - A Key Management Architecture for SCADA Systems

Supervisory Control And Data Acquisition (SCADA) systems are widely used in the management of critical infrastructure such as electricity and water distrubution systems. Currently there is little understanding of how to best protect SCADA systems from malicious attacks. We review the constraints and requirements for SCADA security and propose a suitable architecture (SKMA) for secure SCADA communications. The architecture includes a proposed key management protocol (SKMP). We compare the architecture with a previous proposal from Sandia Labs.
