Per-Core DVFS with Switched-Capacitor Converters for Energy Efficiency in Manycore Processors [PDF]

, 2015
Integrating multiple power converters on-chip improves energy efficiency of manycore architectures. Switched-capacitor (SC) dc-dc converters are compatible with conventional CMOS processes, but traditional implementations suffer from limited conversion ...

Efficiency of Magnetic to Kinetic Energy Conversion in a Monopole Magnetosphere [PDF]

, 2009
Unconfined relativistic outflows from rotating, magnetized compact objects are often well-modeled by assuming the field geometry is approximately a split-monopole at large radii.

Electrokinetic Energy Conversion Efficiency in Nanofluidic Channels

Nano Letters, 2006
We theoretically evaluate the prospect of using electrokinetic phenomena to convert hydrostatic energy to electrical power. An expression is derived for the energy conversion efficiency of a two-terminal fluidic device in terms of its linear electrokinetic response properties.
