Performance of Soil Moisture Sensors at Different Salinity Levels: Comparative Analysis and Calibration

open access: yesSensors
Soil dielectric sensors have been widely used to obtain real-time soil moisture data, which are important for water resource management. However, soluble salts in the soil significantly affect the accuracy of these sensor measurements.

CUDAS: Distortion-Aware Saliency Benchmark

open access: yesIEEE Access, 2023
Visual saliency prediction remains an academic challenge due to the diversity and complexity of natural scenes as well as the scarcity of eye movement data on where people look in images.

Body Image Distortion and Dissatisfaction in a Mexican sample [PDF]

open access: yesRevista de Psicología y Ciencias del Comportamiento de la Unidad Académica de Ciencias Jurídicas y Sociales, 2018
The present study analyzes the relationship between body image satisfaction and distortion with the body mass index (BMI). Participants were 540 students from different schools of middle and higher level from Monterrey, Mexico; age ranked from 16 to 25 ...

Combination of Thermal and Mechanical Strategies to Compensate for Distortion Effects during Profile Grinding

open access: yesMachines, 2022
This paper describes the investigations and the results of an analysis of distortion compensation processes for profile grinding. Steel workpieces often change their residual stress state due to machining in a seemingly uncontrolled matter.

Distortions of the helicoid

open access: yesGeometriae Dedicata, 2008
Colding and Minicozzi have shown that an embedded minimal disk $0\inΣ\subset B_R$ in $\Real^3$ with large curvature at 0 looks like a helicoid on the scale of $R$. Near 0, this can be sharpened: on the scale of $|A|^{-1}(0)$, $Σ$ is close, in a Lipschitz sense, to a piece of a helicoid.

A perspective on distortions [PDF]

open access: yes2003 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003. Proceedings., 2003
A framework for analyzing distortions in non-single viewpoint imaging systems is presented. Such systems possess loci of viewpoints called caustics. In general, perspective (or undistorted) views cannot be computed from images acquired with such systems without knowing scene structure.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Research progress in regulation of residual stress and distortion in wire arc additive manufacturing

open access: yesCailiao gongcheng
Wire arc additive manufacturing (WAAM) employs an arc as the energy source to melt metal wire layer by layer, making it suitable for the rapid fabrication of medium to large-sized complex metal components.
