Ingham type approach for uniform observability inequality of the semi-discrete coupled wave equations

open access: yesElectronic Journal of Differential Equations, 2020
This article concerns an observability inequality for a system of coupled wave equations for the continuous models as well as for the space semi-discrete finite difference approximations.

Boosting the Energy Density of “Anode‐Free” Lithium Metal Batteries via Electrospun Polymeric Scaffolds

open access: yesAdvanced Functional Materials, EarlyView.
While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

Observing the Observers

open access: yes, 2020
In this chapter, I reflect on the origins of the Observing Teachers project. I make links to two facets of observer dependence: the dependence of the origins and conduct of the project on the researchers who originated and conducted it; and the methods we adopted and adapted to allow us to position the teachers as observers in the research.

Observability-Based Gaussian Sum Cubature Kalman Filter for Three-Dimensional Target Tracking Using a Single Two-Dimensional Radar

open access: yesRemote Sensing
This paper considers the problem of tracking a three-dimensional target under the condition that only a single two-dimensional radar is available. Since a two-dimensional radar can only measure the slant range and azimuth information relative to the ...

Defect‐Mediated Scintillation in Fully Inorganic Perovskites via Water‐Induced 0D/3D Phase Modulation

open access: yesAdvanced Functional Materials, EarlyView.
A reproducible synthesis to control 3D/0D phase ratios via water‐tuned solvent–antisolvent methods is presented. Enhanced scintillation yield and ultrafast decay are achieved. Defect‐driven emission mechanisms are revealed through cathodoluminescence and radioluminescence, shedding light on the underexplored role of the 0D Cs4PbBr6 and mixed 0D/3D ...

Power System Topological Observability Analysis Using Improved Hopfield Neural Network [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2016
This paper solves the Topological Observability (TO) problem of a power system using the new methodology based on Improved Hopfield Neural Network (IHNN). This IHNN can solve the combinatorial optimization problem with inequality constraints.

Photoluminescent UV Light Modulation via Anisometric Carbon Nanodots for UV–Visible Shutter and UV Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Measurement configuration for integrated electric–gas systems via observability analysis considering gas flow dynamics

open access: yesIET Energy Systems Integration
State estimation plays an important role in the monitoring and control of integrated electric–gas systems (IEGSs), but it faces limitations due to insufficient measurement configurations and low data redundancy in these systems; additional measurement ...

When and why does observability increase honesty? The role of gossip and reputational concern

open access: yesJudgment and Decision Making
People frequently engage in dishonest behavior, which entails costs to society. A common advice to increase honesty is to enhance observability. However, previous research produced conflicting findings, making it unclear when and why observability ...
