ANALYSIS OF THE VARIATION OF VIBRATIONS THAT APPEAR DURING TURNING WORKS WITH TRANSVERSE FEED DUE TO THE MODIFICATION OF THE FUNCTIONAL GEOMETRY OF THE CUTTING TOOL [PDF]
Fiabilitate şi Durabilitate, 2023 The paper aims to analyze the way in which the variation of the vibrations that appear during the machining processes by chipping during the transverse turning operation evolves due to the variation of the functional geometry of the chipping tool.

Exploring the Optimal 4D-SfM Photogrammetric Models at Plot Scale
Remote Sensing, 2023 Structure from Motion (4D-SfM) photogrammetry can capture the changes in surface processes with high spatial and temporal resolution, which is widely used to quantify the dynamic change process of the ground surface.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Geometry-based mass grading of mango fruits using image processing
Information Processing in Agriculture, 2017 Mango (Mangifera indica) is an important, and popular fruit in Bangladesh. However, the post-harvest processing of it is still mostly performed manually, a situation far from satisfactory, in terms of accuracy and throughput.

Unsupervised deep homography with multi‐scale global attention
IET Image Processing, 2023 Homography estimation serves an important role in many computer vision tasks. Depending heavily on hand‐craft feature quality, traditional methods degenerate sharply in scenes with low texture.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Development of a deep learning platform for optimising sheet stamping geometries subject to manufacturing constraints [PDF]
arXiv, 2022 The latest sheet stamping processes enable efficient manufacturing of complex shape structural components that have high stiffness to weight ratios, but these processes can introduce defects. To assist component design for stamping processes, this paper presents a novel deep-learning-based platform for optimising 3D component geometries.

Modular discretization of the AdS2/CFT1 Holography [PDF]
, 2013 We propose a finite discretization for the black hole geometry and dynamics. We realize our proposal, in the case of extremal black holes, for which the radial and temporal near horizon geometry is known to be AdS$_2=SL(2,\mathbb{R})/SO(1,1,\mathbb{R})$.
