Performance Criterion of Phasor Measurement Units for Distribution System State Estimation
IEEE Access, 2019 A phasor measurement unit (PMU) is a device that can directly measure the phase angles of voltages and currents, with high accuracy, using accurate time signals.

State estimation: direct state measurement vs. tomography
, 2013 We compare direct state measurement (DST or weak state tomography) to conventional state reconstruction (tomography) through accurate Monte-Carlo simulations. We show that DST is surprisingly robust to its inherent bias.

State Variable Implications on Hydraulic State Estimation
Water Resources Management, 2022 AbstractHydraulic State Estimation allows to estimate the most likely state of a water supply network considering multiple sources of information and their associated uncertainty. It is set out as an optimization problem, often addressed according to the Weighted Least Squares criterion. It can be formulated differently depending on the selected set of

Temporal Segmentation of Surgical Sub-tasks through Deep Learning with Multiple Data Sources [PDF]
, 2020 Many tasks in robot-assisted surgeries (RAS) can be represented by finite-state machines (FSMs), where each state represents either an action (such as picking up a needle) or an observation (such as bleeding).

A Statistical Approach for Distribution System State Estimation
Turkish Journal of Electrical Power and Energy SystemsPower system state estimation is a useful technique that enables the system to be monitored when sufficient measurements are not available. Although it has been practiced for a long time, distribution system state estimation (DSSE) is still challenging ...

Estimating State‐Contingent Production Frontiers [PDF]
American Journal of Agricultural Economics, 2006 Chambers and Quiggin (2000) use state‐contingent representations of risky production technologies to establish important theoretical results concerning producer behavior under uncertainty. Unfortunately, perceived problems in the estimation of state‐contingent models have limited the usefulness of the approach in policy formulation.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.
