Weak observability estimates for 1-D wave equations with rough coefficients [PDF]
, 2013 In this paper we prove observability estimates for 1-dimensional wave equations with non-Lipschitz coefficients. For coefficients in the Zygmund class we prove a "classical" observability estimate, which extends the well-known observability results in ...

Geometric control condition for the wave equation with a time-dependent observation domain [PDF]
, 2016 We characterize the observability property (and, by duality, the controllability and the stabilization) of the wave equation on a Riemannian manifold $\Omega,$ with or without boundary, where the observation (or control) domain is time-varying.

Enhancing Observability in Distribution Grids Using Smart Meter Data [PDF]
IEEE Transactions on Smart Grid, 2016 Due to limited instrumentation, distribution grids are currently challenged by observability issues. On the other hand, smart meter data are communicated to utility operators from nodes with renewable generation and elastic demand.

Low Regularity Ray Tracing for Wave Equations with Gaussian beams [PDF]
, 2018 We prove observability estimates for oscillatory Cauchy data modulo a small kernel for $n$-dimensional wave equations with space and time dependent $C^2$ and $C^{1,1}$ coefficients using Gaussian beams. We assume the domains and observability regions are

The Oracle Problem When Testing from MSCs [PDF]
, 2013 Message Sequence Charts (MSCs) form a popular language in which scenario-based specifications and models can be written. There has been significant interest in automating aspects of testing from MSCs.

Observability of nonlinear systems with unmeasured inputs
Mechanical systems and signal processing, 2019 This paper presents a geometric algorithm to investigate the theoretical observability of nonlinear systems with partially measured inputs and outputs. The algorithm is based on Lie algebra and applies to systems whose state and measurement equations are

Observability Through a Matrix-Weighted Graph [PDF]
IEEE Transactions on Automatic Control, 2016 Observability of an array of identical linear time-invariant systems with incommensurable output matrices is studied, where an array is called observable when identically zero relative outputs imply synchronized solutions for the individual systems.
