Wireless Inertial Measurement Units (WIMUs) combine motion sensing, processing & communications functionsin a single device. Data gathered using these sensors has the potential to be converted into high quality motion data. By outfitting a subject with multiple WIMUs full motion data can begathered. With a potential cost of ownership several orders of magnitude less than traditional camera based motion capture, WIMU systems have potential to be crucially important in supplementing or replacing traditional motion capture and opening up entirely new application areas and potential markets particularly in the rehabilitative, sports & at-home healthcarespaces. Currently WIMUs are underutilized in these areas. A major barrier to adoption is perceived complexity. Sample rates, sensor types & dynamic sensor ranges may need to be adjusted on multiple axes for each device depending on the scenario. As such we present an advanced WIMU in conjunction with a Smart WIMU system to simplify this aspect with 3 usage modes: Manual, Intelligent and Autonomous. Attendees will be able to compare the 3 different modes and see the effects of good andbad set-ups on the quality of data gathered in real time.

The contribution of buildings towards total worldwide energy consumption in developed countries is between 20% and 40%. Heating Ventilation and Air Conditioning (HVAC), and more specifically Air Handling Units (AHUs) energy consumption accounts on average for 40% of a typical medical device manufacturing or pharmaceutical facility’s energy consumption. Studies have indicated that 20 – 30% energy savings are achievable by recommissioning HVAC systems, and more specifically AHU operations, to rectify faulty operation. Automated Fault Detection and Diagnosis (AFDD) is a process concerned with potentially partially or fully automating the commissioning process through the detection of faults. An expert system is a knowledge-based system, which employs Artificial Intelligence (AI) methods to replicate the knowledge of a human subject matter expert, in a particular field, such as engineering, medicine, finance and marketing, to name a few. This thesis details the research and development work undertaken in the development and testing of a new AFDD expert system for AHUs which can be installed in minimal set up time on a large cross section of AHU types in a building management system vendor neutral manner. Both simulated and extensive field testing was undertaken against a widely available and industry known expert set of rules known as the Air Handling Unit Performance Assessment Rules (APAR) (and a later more developed version known as APAR_extended) in order to prove its effectiveness. Specifically, in tests against a dataset of 52 simulated faults, this new AFDD expert system identified all 52 derived issues whereas the APAR ruleset identified just 10. In tests using actual field data from 5 operating AHUs in 4 manufacturing facilities, the newly developed AFDD expert system for AHUs was shown to identify four individual fault case categories that the APAR method did not, as well as showing improvements made in the area of fault diagnosis.

This dissertation carries out a dialogue between Maurice Merleau-Ponty and Nishida Kitarō concerning their theories of artistic expression and faith. Both philosophers go through remarkably similar trajectories in their philosophic projects: In their early works they focus on the motor-perceptual body of the artist, and as they move towards the mature articulation of their ontologies, the concept of faith becomes central. I propose the term “motor-perceptual faith” to bring these seemingly diverse sets of concerns into a conceptual continuity. My study explores this connection, and argues that the artist’s motor-perceptual expressive body, as colourfully and sometimes poetically articulated in their early works, enacts the form of faith developed more abstractly in their later writings. Exploring these relations fosters a mutual expansion of the early by the later works, thus thickening the concept of faith by seeing it as enacted by the artist, while enlarging the concept of artistic expression by understanding it as a practice of motor‐perceptual faith. Framing these philosophers as putting forth a traditionally religious concept as illustrated by way of artistic expression, offers a new articulation of both of their writings, an important conceptual bridge between the two, while challenging un-ambiguous distinctions between art, philosophy and religion, and ultimately philosophy East and West.
