• Off-centre load-insensitive digital quartz resonator force sensor

Publication Year: 2001, Page(s):215 - 220
Cited by:  Papers (1)
| | PDF (600 KB)

A digital output force sensor has been developed utilising a unique elastic structure and an AT-cut quartz crystal resonator (QXR) based on an energy trapping effect as sensing element. The force-sensitive QXR is preloaded into the elastic structure, through which a force proportional to the applied force is exerted on the QXR, and the force measurement is accomplished by measuring frequency chang...

• Online validation of the measurement uncertainty of a sensor using wavelet transforms

Publication Year: 2001, Page(s):210 - 214
| | PDF (520 KB)

The measurement uncertainty of a sensor as a measure of its accuracy is normally derived through static analysis. Conventionally, uncertainty analysis is conducted during the design and development stage of a sensor to select appropriate components and measurement techniques, as well as interpreting its experimental data. The demand for quality assurance by measurement is now increasing. It is the... View full abstract»

• Ultrasonic fault detection by processing of signals from fixed transceiver system

Publication Year: 2001, Page(s):204 - 209

| | PDF (536 KB)

An ultrasonic nonscanning method of flaw detection employing coded excitation with a new approach to the signal processing is investigated. An ultrasonic M-sequence signal is transmitted through the medium under investigation and reflections from faults are received by plural receivers at different positions. The cross correlation function between the original M-sequence and the reflected signal i... View full abstract»

• CMOS compatible fabrication methods for submicron Josephson junction qubits

Publication Year: 2001, Page(s):225 - 228

| | PDF (552 KB)

The authors have developed two distinct processes for the fabrication of mesoscopic Josephson junction qubits that are compatible with conventional CMOS processing. These devices, based on superconducting Al/Al2O3/Al tunnel junctions, are fabricated by electron beam lithography using single-layer and multilayer resists. The new single-layer resist process is found to have sig... View full abstract»

• Quantum states of small superconductors

Publication Year: 2001, Page(s):233 - 236
| | PDF (608 KB)

After a brief review of recent proposals for using small superconductors whose charging energy is comparable to their superconducting gap as physical qubits in quantum computation, the Cooper-pair box' experiments of Y. Nakamura et al. (1999, 2000) are analysed. In these, the gate voltage on a small superconducting island is perturbed by a pulse of height δV and duration Δt and cohere... View full abstract»

• Electricity generation in the home: modelling of single-house domestic combined heat and power

Publication Year: 2001, Page(s):197 - 203
Cited by:  Papers (1)
| | PDF (608 KB)

Two models for predicting potential savings from a domestic combined heat and power unit are developed and compared. The first, a simple spreadsheet calculation based on heating times and energy bills, gives a basic indication of the benefits of domestic combined heat and power. The second predicts the electricity and heat demand profiles of homes based on building structure, weather information a... View full abstract»

• Mesoscopic Josephson arrays interacting with non-classical electromagnetic fields and their applications

Publication Year: 2001, Page(s):229 - 232
| | PDF (360 KB)

A ring made from a Josephson array in the insulating phase is considered. The ring contains a dual Josephson junction' (Josephson junction for vortices). External non-classical electromagnetic fields are coupled to the device and interact with the vortices that circulate the ring. The time evolution of this two-mode fully quantum mechanical system is studied. The effect of the quantum statistics ... View full abstract»
