Orientation Control System: Enhancing Aerial Maneuvers for Quadruped Robots

open access: yesSensors, 2023
For legged robots, aerial motions are the only option to overpass obstacles that cannot be circumvented with standard locomotion gaits. In these cases, the robot must perform a leap to either jump onto the obstacle or fly over it.

Laplacian spectral determination of path-friendship graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
A graph G is said to be determined by the spectrum of its Laplacian matrix (DLS) if every graph with the same spectrum is isomorphic to G. In some recent papers it is proved that the friendship graphs and starlike trees are DLS. If a friendship graph and

Study of in vitro poorly soluble drug solubility into fasted state simulated intestinal fluid reflective of in vivo gastrointestinal variability

open access: yesBritish Journal of Pharmacy, 2023
Solubility and dynamic light scattering (DLS) studies of three poorly soluble drugs(naproxen, indomethacin and phenytoin) in simulated intestinal fluid (SIF) were carried out in order to calculate the number of drug molecules per micelle based on the ...

Development of a downstream process for purification and purity analysis of glutaminase free L-asparaginase using UPLC, DLS-ZP and DSC-TGA

open access: yesJournal of Taibah University for Science, 2021
Several bacterial strains were isolated from soil and water in the current work and screened for glutaminase-free L-asparaginase activity. The selected strain was subjected to the production of glutaminase-free L-asparaginase and thereby purification ...
