Multi-Channel Assessment Policies for Energy-Efficient Data Transmission in Wireless Underground Sensor Networks

open access: yesEnergies, 2023
Wireless Underground Sensor Networks (WUGSNs) transmit data collected from underground objects such as water substances, oil substances, soil contents, and others. In addition, the underground sensor nodes transmit the data to the surface nodes regarding

Lattice distortion in a strong and ductile refractory high-entropy alloy

open access: yesActa Materialia, 2018
The maximization of the mixing entropy with the optimal range of enthalpy in high-entropy alloys (HEAs) can promote the formation of a stable single solid-solution phase with the absence of competing intermetallic compounds.

Measurements and Modeling of the Nonlinear Behavior of a Guitar Pickup at Low Frequencies †

open access: yesApplied Sciences, 2017
Description of the physical behavior of electric guitars is still not very widespread in the scientific literature. In particular, the physical models describing a nonlinear behavior of pickups still requires some refinements. The study presented in this

Distortion Varieties

open access: yesFoundations of Computational Mathematics, 2017
The distortion varieties of a given projective variety are parametrized by duplicating coordinates and multiplying them with monomials. We study their degrees and defining equations. Exact formulas are obtained for the case of one-parameter distortions. These are based on Chow polytopes and Gröbner bases.

Ultrastrong Medium‐Entropy Single‐Phase Alloys Designed via Severe Lattice Distortion

open access: yesAdvances in Materials, 2018
Severe lattice distortion is a core effect in the design of multiprincipal element alloys with the aim to enhance yield strength, a key indicator in structural engineering. Yet, the yield strength values of medium‐ and high‐entropy alloys investigated so

Video Compression With Rate-Distortion Autoencoders [PDF]

open access: yesIEEE International Conference on Computer Vision, 2019
In this paper we present a a deep generative model for lossy video compression. We employ a model that consists of a 3D autoencoder with a discrete latent space and an autoregressive prior used for entropy coding.

On Optimum End-to-End Distortion in MIMO Systems [PDF]

open access: yes, 2010
This paper presents the joint impact of the numbers of antennas, source-to-channel bandwidth ratio and spatial correlation on the optimum expected end-to-end distortion in an outage-free MIMO system. In particular, based on an analytical expression valid
