Real-Time Kinematic Imagery-Based Automated Levelness Assessment System for Land Leveling

open access: yesAgriculture, 2023
Many cropping systems, notably for rice or soybean production, rely largely on arable land levelness. In this study, an automated levelness assessment system (ALAS) for evaluating lowland levelness is proposed.

Rotation and pseudo-rotation [PDF]

open access: yesGeneral Relativity and Gravitation, 2005
Eigenvectors of stress-energy tensor (the source in Einstein's equations) form privileged bases in description of the corresponding space-times. When one or more of these vector fields are rotating (the property well determined in differential geometry), one says that the space-time executes this rotation.

Effect of Black Garlic Extract on Blood Glucose, Lipid Profile, and SGPT-SGOT of Wistar Rats Diabetes Mellitus Model

open access: yesMajalah Kedokteran Bandung, 2019
Dyslipidemia is one of the complications of diabetes mellitus (DM) that can lead to elevated total cholesterol, TG, and LDL. Increased SGOT-SGPT indicates damage of hepatic cells.

Rotating rotated branes [PDF]

open access: yesJournal of High Energy Physics, 1999
We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry.
