Linear Cutting Blocking Sets and Minimal Codes in the Rank Metric [PDF]

open access: yesJournal of Combinatorial Theory, 2021
This work investigates the structure of rank-metric codes in connection with concepts from finite geometry, most notably the $q$-analogues of projective systems and blocking sets.

Near-Capacity Irregular Precoded Linear Dispersion Codes [PDF]

open access: yes, 2008
In this treatise, we propose a novel serial concatenated RSC-coded Irregular Precoded Linear Dispersion Codes (IR-PLDC), which is capable of operating near MIMO channel’s capacity.

Full Characterization of Minimal Linear Codes as Cutting Blocking Sets [PDF]

open access: yesIEEE Transactions on Information Theory, 2019
In this paper, we first study in detail the relationship between minimal linear codes and cutting blocking sets, recently introduced by Bonini and Borello, and then completely characterize minimal linear codes as cutting blocking sets. As a direct result,

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 ...

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.

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.

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.
