Research Works In Progress (WIP)
This page describes research works (projects) in progress for Professor Jonathan Scott.
The aim is to impart some idea of how I spread my time.
Linear HBT amplifiers and the Cascomp configuration
This is a project to look at increasing the TOI (3rd Order Intercept Point, a measure of circuit distortion) of GaAs HBT amplifiers using the Cascomp configuration. Project is supported by Agilent HFTC and EEsof divisions.
Microwave impulse applications
The aim is to develop applications for U9391C impulse (comb) generators.
Impulse TDR (iTDR) is being explored, especially applied to antenna characterisation without need for
an anechoic chamber. The project is also looking applying iTDR to pasture analysis. The project enjoys support from Agilent's test accessories R&D group in Penang.
The project centers around building an instrument that looks like a Vector Network Analyzer (VNA) but with sound in pipes rather than EM waves. The hardware is based on a commercial, 500MHz Agilent VNA. The project is funded through a collaboration with Gallagher.
Automation of Coffee roasting
This work revolves around the recebnt trends for coffee to be roasted closer to point of use. Heuristic and innovative control of the
roasting process aims at endpoint determination without human help.
Bacteria detection by RF/microwave dielectric measurement
The project, based in Agresearch, seeks to use high-frequency dielectric measurement to sense bacteria in biofilm or similar medium. We are looking for a bacterial dielectric fingerprint, or a dielectric betrayal of binding with a specific antigen.
Harvesting water meter
This project looks at the design and power budget for remote sensors, especially water meters, based on recent ultra-low power microcontrollers. It addresses separately the power requirements for logging and wireless reporting, especially of water usage in domestic setting, the prospects for extraction of power (harvesting) in the same situation particularly without moving parts, and hardware and software protocols appropriate for reporting usage to a host.
Practical battery gauge
Sergej S, but unstaffed after February 2011.
A lead-acid state-of-charge meter has been developed that is simple to install and use. How to prove that it is robust, satisfactory, and superior?
iDCC Not staffed after February 2011.
This project concerns user interface, and ways of dealing with bus-system address concerns without the interaction of a person aware of the technical issues at work. A design is proposed that could do for model trains what the Mac did for the personal computer. The hardware has yet to be refined, and the UI superiority proven.
A tap timer that adjusts its action in response to environmental conditions without human input could save water and simultaneously log that saving, without the user even being aware that the system is present or operating. This has significant commercial possibilities, but the design has to be robust, and its value must be proven for it to be accepted or legislated.
SOS power harvester ICs
Not yet staffed.
A collaboration with Silanna Semiconductor in Australia using SOS CMOS to develop an IC that will achieve record-breaking harvester power supply efficiency. In collaboration with Bill Redman-White from Southampton University in the UK.
Ultramicro Programming book
Jim R and Jonathan S .
A book on the thoery and techniques specific to programming 8-but SoC ultra-microcontrollers. Theoretical and heretical. Proposed for Wiley.
Ann, Bronwen, Jonathan, et al
A research project to examing the pedagogical potential of Threshold Concepts. Marsden and TLRI applications proposed.
Involved with ENEL111 and other EE undergraduate courses. A longitudinal study is the aim.
Videorecording of all my ENEL111 lectures
Panopto will capture electronic whiteboard, PC, webcam, document camera and scope screen simultaneously.
The course has Threshold-Concept emphasis, and plans to introduce some peer-teaching in lectures.
For 6 weeks starting Feb 2011.
A project to develop a battery-powered 7.25" locomotive as an Open Day demonstration and a vehicle for testing
batteries in a non-road environment.
