Probabilistic design: The future of rock engineering

A brief background to the development of the rock engineering design process is given, showing that since the development of the science of mathematics, deterministic methods have been used to perform various calculations. The variability of rock properties and support characteristics have always been known. However, they were not explicitly used in design but compensated for by the use of a sa...

Recent topics in NMR imaging and MRI.

NMR and NMR imaging (MRI) are finding increasing use not only in the clinical and medical fields, but also in material, physicochemical, biological, geological, industrial and environmental applications. This short review is limited to two topics: (i) new techniques and pulse sequences and their application to non-clinical fields that may have clinical application; and (ii) new trends in MR con...

Recent Topics in Power Management Circuits

This paper summarizes recent research at the author’s laboratory into power management circuitry, including: (1) Envelope-tracking power supplies for base station power amplifiers, (2) Digital PWM generator circuitry, (3) Spreadspectrum clocking for EMI reduction in digitally-controlled power supplies, (4) High-efficiency coupled-inductor DC-DC converters with fast response and low ripple, and ...

The "Soft" Topics in Software Engineering Education

Engineering educators struggle with “soft” topics – topics which include a social element. Soft engineering topics are distinct from the scientific and mathematical underpinnings of engineering. Students frequently complain when these topics are integrated into engineering curricula. Engineering educators also express concerns that they lack both preparation and ability to teach these topics. S...
