Tight Bounds on the Simultaneous Estimation of Incompatible Parameters

open access: yesPhysical Review X, 2021
The estimation of multiple parameters in quantum metrology is important for a vast array of applications in quantum information processing. However, the unattainability of fundamental precision bounds for incompatible observables greatly diminishes the ...

An Efficient Stochastic Linearisation Procedure for the Seismic Optimal Design of Passive Control Devices

open access: yesFrontiers in Built Environment, 2020
The seismic response of structures is often enhanced by introducing passive control devices that can operate through the dissipation of the input energy or by modifying the dynamic characteristics of the main structure.

Aeroacoustic analysis based on FW–H analogy to predict low-frequency in-plane harmonic noise of a helicopter rotor in hover

open access: yesArchives of Mechanics, 2022
The integral formulation of the Ffowcs-Williams and Hawkings (FW–H) analogy, developed by Farassat (known as Farassat’s formulation 1A), is implemented to study the sound generation and propagation of rotating slender bodies.

MAS: a versatile Landau-fluid eigenvalue code for plasma stability analysis in general geometry

open access: yesNuclear Fusion, 2023
We have developed a new global eigenvalue code, multiscale analysis for plasma stabilities (MAS), for studying plasma problems with wave toroidal mode number ( n ) and frequency ( ω ) in a broad range of interest in general tokamak geometry, based on a ...

Absolute Position Coding Method for Angular Sensor—Single-Track Gray Codes

open access: yesSensors, 2018
Single-track Gray codes (STGCs) is a type of absolute position coding method for novel angular sensors, because it has single-track property over traditional Gray codes and mono-difference over linear feedback shift register codes.

Generic constructions of PoRs from codes and instantiations

open access: yesJournal of Mathematical Cryptology, 2019
In this paper, we show how to construct – from any linear code – a Proof of Retrievability (𝖯𝗈𝖱{\mathsf{PoR}}) which features very low computation complexity on both the client (𝖵𝖾𝗋𝗂𝖿𝗂𝖾𝗋{\mathsf{Verifier}}) and the server (𝖯𝗋𝗈𝗏𝖾𝗋{\mathsf{Prover}}) sides,

DIFFERENTIATION OF POLYNOMIALS IN SEVERAL VARIABLES OVER GALOIS FIELDS OF FUZZY CARDINALITY AND APPLICATIONS TO REED-MULLER CODES

open access: yesAdvanced Engineering Research, 2018
Introduction. Polynomials in several variables over Galois fields provide the basis for the Reed-Muller coding theory, and are also used  in a number of cryptographic problems.

The SMEFTsim package, theory and tools

open access: yesJournal of High Energy Physics, 2017
We report codes for the Standard Model Effective Field Theory (SMEFT) in FeynRules — the SMEFTsim package. The codes enable theoretical predictions for dimension six operator corrections to the Standard Model using numerical tools, where predictions can ...

Symmetry, Outer Bounds, and Code Constructions: A Computer-Aided Investigation on the Fundamental Limits of Caching

open access: yesEntropy, 2018
We illustrate how computer-aided methods can be used to investigate the fundamental limits of the caching systems, which are significantly different from the conventional analytical approach usually seen in the information theory literature.
