Changes in snow’s influence on surface ground temperature (SGT) could create a bias
in the borehole temperature record of climate change. Using a snow-ground thermal model
which predicts changes in the mean annual offset between SGT and surface air
temperature (SAT), we calculate the response of SGT to changes in...
Digital phase-locked loops (PLLs) have been receiving increasing attention recently due to their ease of integration, scalability and performance comparable to their analog counterparts. In digital PLLs, increased resolution in time-to-digital conversion is desirable for improved noise performance. This work describes the design and simulation of a stochastic time-to-digital converter...
The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected.
Current signature...
