Design and Control of Sensorless, Brushless, Linear Permanent Magnet Motors for Fluid Pumping. Many machines require reciprocating motion and achieve it by mechanical conversion of rotary motion. In particular, pistons for liquid pumping and gas compression are usually driven by a crank on a rotary electric motor. Driving the piston directly by a linear motor eliminates the cost, weight, inefficiency and wear of the mechanical conversion. This project will design, construct and test high efficie ....Design and Control of Sensorless, Brushless, Linear Permanent Magnet Motors for Fluid Pumping. Many machines require reciprocating motion and achieve it by mechanical conversion of rotary motion. In particular, pistons for liquid pumping and gas compression are usually driven by a crank on a rotary electric motor. Driving the piston directly by a linear motor eliminates the cost, weight, inefficiency and wear of the mechanical conversion. This project will design, construct and test high efficiency, tubular, linear permanent magnet motors for fluid pumping. Further, an intelligent electronic controller will be developed to control the motor speed and reversals without sensors in the motor. Initial applications will be solar powered water pumping and purification.Read moreRead less

Hardware Acceleration for Neural Systems. To really understand how brains work, we need to simulate neural networks of a size similar to that of the human brain (100 billion neurons, 100 trillion connections). Simulating such a network on standard computers in not possible because of its sheer size. Several groups are currently building very expensive and proprietary hardware to solve this, but the output from these projects will not be accessible to other researchers.

To really understand how brains work, we need to simulate neural networks of a size similar to that of the human brain (100 billion neurons, 100 trillion connections). Simulating such a network on standard computers in not possible because of its sheer size. Several groups are currently building very expensive and proprietary hardware to solve this, but the output from these projects will not be accessible to other researchers. In order to make real progress in neuroscience, many more researchers need to be enabled to participate. To do this, the project will build a system from commercial hardware (FPGAs) that will cost only a few ten thousand dollars and it will make this design and software available for free.

We will develop electronic building blocks to investigate biological signal processing. In particular, we will investigate the auditory pathway and develop the most accurate electronic model of the biological cochlea and auditory nerve. These will be followed by electronic circuits that model the processing of sensory signals in the brain. Processing signals with neural spikes offers distinct advantages over current analogue and digital signal processing techniques in terms of noise, energy consumption and extraction of temporal information. We will implement the first spike-based models of pitch and timbre perception, and a neural model of speech recognition in noisy environments.Read moreRead less
