Low-Rate Non-Intrusive Load Disaggregation with Graph Shift Quadratic Form Constraint
Applied Sciences, 2018 Non-intrusive load monitoring (NILM) is a cost-effective technique for extracting device-level energy consumption information by monitoring the aggregated signal at the entrance of the electric power.

Normal modes for two-dimensional gravitating kinks
Physics Letters B, 2022 We study small perturbations around an arbitrary static kink solution of a two-dimensional (2D) gravity-scalar system, where the gravity part is described by a subclass of 2D dilaton gravity theory, and the scalar matter field has generalized dynamics ...

Period Change of W UMa Type Contact Binary AB And [PDF]
Journal of Astronomy and Space Sciences, 1997 The CCD photometric observations of W UMa-type eclipsing binary AB And were made from September 1994 to October 1996. New four primary minimum times were obtained form these observations.

Estimating quadratic variation using realized variance [PDF]
Journal of Applied Econometrics, 2002 AbstractThis paper looks at some recent work on estimating quadratic variation using realized variance (RV)—that is, sums ofMsquared returns. This econometrics has been motivated by the advent of the common availability of high‐frequency financial return data. When the underlying process is a semimartingale we recall the fundamental result that RV is a

Monte Carlo burnup and its uncertainty propagation analyses for VERA depletion benchmarks by McCARD
Nuclear Engineering and Technology, 2018 For an efficient Monte Carlo (MC) burnup analysis, an accurate high-order depletion scheme to consider the nonlinear flux variation in a coarse burnup-step interval is crucial accompanied with an accurate depletion equation solver.

Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis
Arthritis Care &Research, EarlyView.Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.
