Compensation of Distribution System Voltage using DVR [PDF]
, 2002 A dynamic voltage restorer (DVR) is a power-electronic controller that can protect sensitive loads from disturbances in the supply system. In this paper, it is demonstrated that this device can tightly regulate the voltage at the load terminal against ...

Finite elements and the discrete variable representation in nonequilibrium Green's function calculations. Atomic and molecular models [PDF]
, 2009 In this contribution, we discuss the finite-element discrete variable representation (FE-DVR) of the nonequilibrium Green's function and its implications on the description of strongly inhomogeneous quantum systems.

Bökstedt periodicity and quotients of DVRs
Compositio Mathematica, 2022 In this paper we compute the topological Hochschild homology of quotients of discrete valuation rings (DVRs). Along the way we give a short argument for Bökstedt periodicity and generalizations over various other bases. Our strategy also gives a very efficient way to redo the computations of $\operatorname {THH}$ (respectively, logarithmic ...

Renal pericytes: regulators of medullary blood flow [PDF]
, 2012 Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.
